INTRODUCTION Since becoming an independent state Ukraine has experienced high levels of both inflation and budget deficit, making itself an interesting case study of the relationship between the two fundamental indicators. In early 90-s consumer price inflation reached a 10000% a year, the highest level among transition economies not at war. Budget deficits exceeded 10% of GDP. As economic policy become more constructive, the budget deficit level diminished. The rate of inflation declined even more sharply to moderate levels. This can be clearly seen as a proof of the deficitinduced hyperinflation. The major source of deficit financing had been National bank credits. However, as government became able to use other sources of financing of a much smaller deficit, the link and causality between budget deficit and inflation turned to be less evident. Though it is widely acknowledged that fiscal imbalances were by far a major determinant of inflation, there exists no comprehensive study of the impact of the budget deficit on inflation in Ukraine. De Menil (1997) and Banaian et al. (1998) analyzed the issue for the first half of the 1990s. The main finding was that fiscal deficit did matter, but only to the extent it contributed to the money growth. As most of the budget imbalance was being monetized during that period, it is of no surprise that independent influence of the deficit not found. Later on, as more possibilities emerged to finance the deficit — through newly created T-bills market or from external sources — the link between deficit, money and inflation seems to become much more complicated. The goal of this research is to analyze the dynamics of the Ukrainian budget deficit and inflation, try to reveal their mutual impacts, and summarize the lessons from the second half of the 1990s’ experience. The main hypothesis for empirical testing is whether fiscal imbalance itself helps to explain the inflation dynamics after the hyperinflation period. Based on the monthly data from 1995 to mid-2000 our major finding in VAR specification is the implicit conclusion, that fiscal imbalance, apart from other, purely monetary factors, does play a role in the inflation determination. A monthly 1%GDP decrease in budget deficit, all of which was previously monetized, subtracts from annual inflation 0.8%. If a non-monetized part of the deficit is cut, then annual inflation is lowered by 0.4%. Among the monetary factors, the most inflationary seems to be the monetization of the deficit. The dynamics of the National Bank’s claims to government (monetization) appear to be more tightly linked to the inflation than the monetary base and the exchange rate. The research team of this project consists of Alex Bakun, Maxym Kryshko, Ruslan Piontkivsky (team leader), and Tetiana Sytnyk. The remainder of the report is organized as follows. Section 2 presents a theoretical framework for the analysis. Section 3 describes the historical developments of the budget balance, sources and costs of its financing, and inflation dynamics. In section 4 we explore the relationship empirically and discuss some policy implications. Finally, section 5 is a conclusion. 4 2. THEORETICAL LINKS Generally, budget deficit per se does not cause inflationary pressures, but rather affects price level through the impact on money aggregates and public expectations, which in turn trigger movements in prices. Δ Budget Deficit Δ Monetary Aggregates, Δ Expectations Inflation Money supply link of causality rests on Milton Friedman’s famous thesis that “inflation is always and everywhere a monetary phenomenon”. This thesis means that continuing and persistent growth of prices is necessarily preceded or accompanied by a sustained increase in money supply. The expectations link of causality works through the intertemporal budget constraint, which implies that a government with a deficit must run, in present value-terms, future budget surpluses1. One possible way to generate surpluses is to increase the revenues from seigniorage, so the public might expect future money growth. 2.1 Aggregate Supply and Aggregate Demand Analysis In the monetarist perspective this link looks as follows (see Figure 1). Suppose, money supply is continually increasing, whereas, at the outset, economy is in equilibrium (point A) at full employment and with output at the natural level. If monetary policy is accommodative to budget deficit, money supply continues to rise for a long time, the aggregate demand schedule will shift to the right (AD1 => AD2), thereby causing output to increase above natural level (point A’). However, growing labor demand then pushes wages up, which in turn leads to the shift in aggregate supply leftwards until it reaches AS2 position (AS1 => AS2). In point B the economy has returned to the natural level of output, however, at the higher price level (P2 instead of P1). Figure 1. Aggregate supply and aggregate demand analysis AS3 Price Level P3 P2 P1 AS1 C B’ B A’ A AD3 AD1 Ynat 1 AS2 AD2 Output See, for instance, Walsh (1998, 138-157). 5 If the money supply keeps on growing the next period, aggregate demand will again shift to the right (AD2 => AD3). Then after a while, the AS schedule will move to the left up to the AS3 position. At the same time, the economy has passed the way from point B to point B’, and then to point C. Output has temporarily increased above the natural level, but eventually has declined, while the price level has climbed up to the new height (from P2 to P3)2. Keynesian analysis of the situation predicts the same movements in aggregate demand and aggregate supply curves. The only difference lies in the timing: monetarists stress that the reaction of AS would be quick so that output would not remain above its natural level for a long time, while Keynesians believe this adjustment to be much slower. Fiscal policy or supply-side shocks per se cannot produce consecutive increases in price level. If changes in government expenditures are one-shot and not ever-increasing, then such a policy can generate only a temporary increase in the inflation rate. Moreover, negative aggregate supply shocks cannot produce continually increasing price levels, provided that money supply, and thus aggregate demand, remain unchanged. Basically, these negative supply shocks will bring the economy below the natural level of output and employment and at a higher price level only temporarily. Soon, however, with labor market adjustment the process will go backwards, so that the economy will end up sliding along aggregate demand curve to the initial price level and natural level of output and employment. Thus, we seem to have established that high inflation can only take place along with a high growth of money supply. 2.2 Sources of Financing and Money Decomposition Approaching the first part of the link we try to explain, and ask the question: how it may happen that budget deficits generate movements in money. If the public sector spends more than it receives, such a deficit must somehow be financed in order for the government to pay its bills. The budget constraint of the government can be expressed as follows3: DEF D g Dg1 P (G I g T ) i Dg1 (1) where D g Dg1 is the change in government debt between the current and the previous period, P is the price level, G I g government expenditur es,T taxes, i Dg1 interest payments on previously issued debt. Government debt, in the form of either bonds or credits, can be held by the public (domestic and foreign) and by the central bank. Let’s assume for the purposes of the present report that the central bank’s credit to banking system doesn’t alter over time. Then the change in monetary base (Mh Mh1 ) equals the change in the stock of government debt held by central bank ( Dcg Dcg1 ) plus the change in foreign exchange reserves E ( Bc* Bc*1 ) , where E stands for the nominal exchange rate, we obtain: ( D g Dg1 ) (Mh Mh1 ) ( D pg D pg1 ) E ( Bc* Bc*1 ) (2) Equation tells us that in essence, there are three ways to cover a budget deficit: 2 We may have the same insight into why growth of money supply drives inflation, if we turn to quantity theory of money that relates nominal income, velocity of money and the money supply: P Y M V where PY stands for nominal GDP (price level times real GDP), V denotes velocity of money, and M is the stock of money. If we assume that V and Y changes are relatively small over time, then proportionality between money and prices implies that persistent growth of money supply leads to a proportional rise in price level, i.e. to inflation. 3 Following Sachs and Larrain (1993). 6 by “monetization” of the deficit (i.e. by increasing monetary base or by so called “printing” money); by increase in the public’s (foreign and domestic) holdings of debt; by running down foreign exchange reserves at the central bank. According to Ouanes and Thakur (1997), there exist five different ways of financing budget deficit, closely corresponding to the above version: (i) borrowing from the central bank (or “monetization” of the deficit); (ii) borrowing from the rest of the banking system; (iii) borrowing from the domestic non-bank sector; (iv) borrowing from abroad, or running down foreign exchange reserves; (v) accumulation of arrears. 2.2.1 Borrowing From the Central Bank In other words borrowing from the central bank is called “monetizing” the deficit. Because this method always leads to the growth of monetary base and of money supply, it is often referred to as just “printing money”. As can readily be seen from equation (2), here increase in the high-powered money is the source of financing budget deficit. Monetization occurs (i) when the central bank directly finances budget deficit by lending funds needed to pay government bills; or (ii) when the central bank purchases government debt at the time of issuance or later in the course of open market operations. DEF ( D g Dg1 ) (Mh Mh1 ) ( D pg D pg1 ) E ( Bc* Bc*1 ) If the central bank just lends funds or purchases newly issued government debt, it simply pushes up the stock of high-powered money. It may also be the case that the government first borrows from public or from commercial banking system. However, if the central bank then intervenes and either buys out the debt from the public by means of open market operations or accommodates additional demand for liquidity from banking system, the equivalent amount of reserves gets injected into the economy as if the government originally borrowed from the central bank. In either case budget deficit (DEF) is financed, as can be seen from equation above, by increases in high-powered money. Let us now assume that the government for some reasons can borrow only from the central bank (it has lost the public’s confidence and foreign exchange reserves are near the critical level). Then our budget deficit financing equation will look like: DEF (Mh Mh1 ) E ( Bc* Bc*1 ) (3) If we follow the assumptions of Sachs and Larrain (1993) that Purchasing Power Parity (PPP), as well as quantity theory of money hold, then, under a fixed exchange rate regime, one reaches the following conclusion: even if government tries to borrow from the central bank, and it starts printing money, the bank in effect is running down already depleted foreign exchange reserves, because it has to intervene in foreign exchange market to maintain the fixed exchange rate. This in turn will lead to a reversal of the money supply increase, i.e. ultimately DEF E ( Bc* Bc*1 ) will hold. Although the money supply seems not to have grown much, the resulting upward pressure on exchange rate, stemming from persistent need of financing and entire foreign exchange reserves exhaustion, may end up in currency devaluation, which would then greatly increase inflation. Under a floating exchange rate regime the outcome is different. Let’s now distinguish the nominal (DEF) from real (DEFr) value of budget deficit so that DEF DEFr P . We also assume that the government cannot borrow from public and foreign exchange reserves are zero. For simplicity of presentation, we may approximate the change in high-powered money 7 by the change in money supply (because we know the rapid change in the former necessarily causes the change in latter). Consequently, our equation (3) becomes DEFr P M M 1 or if we rearrange terms DEFr M M 1 . P In other words, the real value of the deficit is now equal to the real value of the change in money supply. The budget deficit in such a situation is said to be financed by collecting seigniorage. In Dornbusch and Fischer’s words (1998), seigniorage refers to “the government’s ability to raise revenue through its right to create money”. The amount of M M 1 . If we rearrange components P M M 1 in this formula and introduce percentage growth in nominal money supply M M and real money balances m , then we obtain that S m . P seigniorage (S) is then given by the expression: S Interestingly, the amount of seigniorage can usefully be decomposed into the “pure seigniorage” and “inflation tax” part. It can be shown4 that: P P1 P1 P P1 , then we )( ) m1 . If we denote the inflation rate as P1 P P1 ) m1 . The first term is referred to as “pure seigniorage” and would have: S m ( 1 S m ( represents the change in real balances. The second term is called “inflation tax” with ( ) being a tax rate and m1 being a tax base. 1 In the words of Dornbusch and Fischer (1998), “inflation acts just like a tax because people are forced to spend less than their income and pay the difference to the government in exchange for extra money. The government thus can spend more resources, and the public less, just as if the government had raised taxes to finance extra spending”. When government finances a deficit by printing money, there are good reasons to believe that the public seeks to maintain real balances so as to offset the effects of inflation. The public therefore chooses to hold more and more nominal money from period to period, so as to keep real balances and thus purchasing power constant in the long run. If this is the case, then m 0 , i.e. the government collects no pure seigniorage, but rather finances the budget deficit entirely through the inflation tax. Thus, we may conclude that under a pure floating exchange rate regime, budget deficit ends up in inflation and, as shown above, the size of the deficit and inflation rate are very closely connected. According to the formula, higher deficits entail higher inflation rates (Sachs and Larrain, 1993). In passing we should note the implication that macroeconomic theory derives about financing a budget deficit through inflation tax: a sustained increase in money growth and in inflation ultimately leads to a reduction in the real money stock (Dornbusch and Fischer 1998). With respect to transition economies, the rationale behind such an implication may be that public S 4 M M 1 M M P P1 M M ( 1 ) 1 1 m M 1 ( ) P P P1 P1 P P P1 m M 1 P P1 P P1 P ( ) m ( ) ( 1 ) m1 P1 P P1 P 8 adjusts to the higher inflation by switching from heavily taxed domestic currency to a different hard and stable currency (e.g. U.S. dollar). So far we have basically considered the most essential mechanisms of financing a budget deficit. However, one additional strong statement that seems appropriate and relevant here should be made. A sustained inflation may stem only from a persistent rather than a temporary budget deficit that is eventually financed by printing money rather than by borrowing from public (Mishkin, 2000). 2.2.2 Borrowing From the Public Borrowing from the public can be exercised either domestically or internationally. The ultimate domestic purchasers of government debt, as pointed out by Ouanes and Thakur (1997), could be: (i) non-bank public; or (ii) banks. The essential difference comes from the likely impact of the operation on money supply and inflation. If the government debt is acquired by non-bank domestic public and then the government immediately spends the proceeds by paying its bills, then monetary base remains unchanged, there is no influence on money supply and therefore no room for inflation. Still, borrowing from public by issuing debt might cause certain inconveniences for policymakers. For example, bond finance of budget deficit may push up interest rates thereby putting pressure on private sector finance and on economic growth. Additionally, the cost of borrowing at such high rates surely increases debt service payments thus adding to future budget expenditures5. If banks acquire the government debt, the consequences with respect to monetary base and money supply may differ. No doubt, government borrowing puts additional pressure on banks' reserves and banks may demand more liquidity from the central bank. If such an extra demand for credit from banks is accommodated and the central bank supplies banks with additional reserves, then in fact monetary base increases, thereby causing a rise in money supply through deposit multiplication and thus fueling inflation. However, if the central bank does not accommodate the extra demand, banks will be forced to reduce credit to the private sector in order to meet the higher demand for government credit by purchasing debt (Ouanes and Thakur, 1997). This reduction is often referred to as crowding out of private spending. The impact of budget deficit on money supply when government borrows from foreign public crucially depends on the exchange rate regime. If the central bank adheres to a fixed exchange regime, then any foreign borrowing must be sterilized in foreign exchange market so as to maintain the exchange rate at the prescribed level. But this means that the central bank has to increase the monetary base by buying up the excess supply of foreign exchange in return for additional reserves that are injected into the system. Yet, when floating exchange rate regime dominates in the economy, external borrowing to finance budget deficit allows the government to avoid the increase in monetary base and money supply and thus prevent inflationary developments. Among consequences of such policy are the appreciation of exchange rate and negative pressures on tradable goods sector due to deterioration of its competitiveness in international markets. 5 However, there exists an alternative view on the problem. Ricardian Equivalence Hypothesis stresses that the borrowing is just deferred taxation. Reduction in taxes is surely to increase current fiscal deficit and therefore requires borrowing. But economic agents are rational and they anticipate future tax increases that the government would need to pay off its debts. That is why they in fact increase current private savings in order to compensate fully for additional future tax burden. In pure formulation, as advocated by Robert Barro (1989), a given tax cut and a fall in government saving will be exactly offset by growth of private savings so that all these pressures allegedly stemming from bond financing of budget deficit simply will not happen: interest rates won’t rise, private sector won’t crowd out etc. It should be noted that empirical evidence doesn’t support the presence of Ricardian Equivalence in developing world and is rather inconclusive as far as developed countries are concerned. 9 2.2.3 Running Down Foreign Exchange Reserves Financing of budget deficit by running down foreign exchange reserves occurs when the central bank first purchases government debt on primary or secondary market (or simply grants a loan to the government) thereby injecting additional reserves to the economy and then trades available foreign exchange reserves for domestic currency to offset the increase of monetary base and money supply. As long as the foreign exchange reserves are available, government can confidently finance the deficit. However, when foreign exchange reserves dry up and approach the level that the private sector believes to be critical, the result can be capital flight and the exchange rate depreciation that adds to inflationary pressures (Ouanes and Thakur, 1997). 2.2.4 Accumulation of Arrears Many contemporary researchers argue that there exists a special form of dealing with budget deficit that in essence aims to hide it. In practice, the part of government spending gets deferred through the accumulation of arrears and is supposed to be disbursed later in coming fiscal years. Government expenditure arrears, which indicate delays in government payments to suppliers or creditors, have become an important fiscal issue in many transition economies. Arrears can lead to underestimates of spending and of the size of the fiscal problem facing a country. Since arrears are a form of forced deficit financing, the government’s borrowing requirement is also understated, which leads to a distorted picture of the sources of credit expansion in the economy. While deficit financing can allow the government to absorb more of the economy’s resources than would otherwise be possible, this initial effect is offset as the rest of the economy responds by raising suppliers’ prices or holding back payments for taxes and fees. Unfortunately, expenditure arrears raise the cost of providing government services (Chu and Hemming, 1991). Arrears may also adversely affect the private sector’s expectations about the future development of the economy. Economic agents may thus anticipate an increase in tax pressure, higher inflation, as well as overall deterioration of financial conditions. These negative expectations are likely to amplify the conventional “deficit-money-inflation” effects that we have already reviewed. Furthermore, the arrears accumulated in previous periods may pose a threat to be carried over to the future periods thus only postponing inflationary pressure. 2.3 Specific Theoretical Hypotheses 2.3.1 Olivera-Tanzi Effect It appears that the “budget deficit-inflation” link in fact exhibits a two-way interaction, i.e. not only budget deficit through its impact on money and expectations produces inflationary pressure, but also high inflation then has a feedback effect pushing up budget deficit. Basically, this process works through significant lags in tax collection. The problem lies in the fact that the time of tax obligations’ accrual and the time of actual payment do not coincide, with payment usually made at a later date. In view of this, high inflation during such a time lag reduces the real tax burden. We may therefore have the following self-strengthening phenomenon: persistence of budget deficit props up inflation, which in turn lowers real tax revenues; a fall in the real tax revenues then necessitates further increase in budget deficit and so on. In economic literature this is usually referred to as the Olivera-Tanzi effect6. 6 This phenomenon was observed and documented for many Latin America countries. 10 As Sachs and Larain (1993) show, the evidence from developing world in the 1980s supports the conclusion that this self-strengthening process may well destabilize an economy and lead to a very high inflation. 2.3.2 Deferred Inflation Effect Some researchers also argue that budget deficit financing by means of accumulating domestic debt seems to just postpone the inflation tax. If government finances its deficit by printing money now, then in the future the burden of servicing existing stock of government debt will be easier. Interest payments that otherwise add to the next periods’ government expenditures will not exert additional pressure on fiscal authority and the deficit will not increase over time. As Sachs and Larrain (1993) put it, “borrowing today might postpone inflation, but at the risk of even higher inflation in the future”. Sargent and Wallace (1981) observed, that when fiscal authority sets the budget independently, the monetary authority could only control the timing of inflation. Let’s assume that initially there is no public debt yet and government budget is balanced. Then, however, for some reasons (tax legislation or increasing expenditures) the government starts running a deficit. If it is financed by selling domestic debt to the public, then, provided that primary deficit remains unchanged, the overall deficit will grow because of the mounting interest burden on the debt. Later, as Sargent and Wallace (1981) stress, it may well be the case that public will be reluctant to acquire more government debt, because they will doubt the government’s ability to service it. They refer to this phenomenon as an assumption of an upper limit on the real stock of debt relative to the size of economy. Then the only option is to use money printing and to collect seigniorage. Provided that fiscal policy determines constraints for monetary policy (i.e. both policies are coordinated so as to finance the budget deficit), the monetary authority will be unable to control money supply and therefore inflation forever. In other words, taking into account the extensive bond financing of the deficit that preceded the critical moment (stock of debt has reached upper limit), “sooner or later, in a monetarist economy, the result is additional inflation” (Sargent and Wallace, 1981). It is so because the principal and interest on the debt accumulated up to now and issued to fight inflation must be financed, at least partially, by seigniorage. However, it seems noteworthy that public-debt-financed deficits do not necessitate a future increase in inflation. The reason is that the government may temporarily defer inflationary pressure so as to implement some sort of restructuring (expenditure cuts or tax increases) before the economy closely approaches the upper limit on public debt. 2.3.3 New Fiscal Theory of Price Level Recently a new direction of theory has emerged, which may also be seen as an extension of the deferred inflation hypothesis. According to the new fiscal theory of the price level (see Komulainen and Pirttila, 2000, Carzoneri, Cumby and Diba, 1998, Woodford, 1994) there can be two regimes for price determination. Under so called “monetary dominant” regime, monetary policy determines the price level, and fiscal policy remains reactive. The government balances its intertemporal constraint taking the inflation as given. In the “fiscal dominant” regime, in contrast, the price level is determined by the intertemporal budget constraint. If the future surpluses fall short of financing the deficit, the price level must adjust — increase, reducing the real value of the government debt. Monetary policy is reactive in “fiscal dominant” regime: money supply just reacts to price level changes to bring the money demand equation in balance. 2.4 Closing Remarks Taking into account the above-mentioned theories, we settle on the following distinction: 11 Short-term inflationary effects can be generated by Central bank (NBU) financing (comprising direct NBU credits, and financing through T-Bill (OVDP) purchases on the primary and secondary markets. This way of financing is directly related to monetary growth; Borrowing from domestic private markets, from international markets, or financing through accumulation of arrears does not necessary imply immediate emission. It may lead, however, to inflationary pressures in the future, or even immediately through expectations formation, if government lacks credibility. Therefore, if empirical analysis finds, that overall fiscal imbalance is more important determinant of the inflation, than its direct monetary growth component, we would be inclined to conclude on fiscal dominancy of the economic policy options. In such a case, the scope for the monetary policy is limited. 12 3. DEVELOPMENTS 3.1 Definitions There exist different versions of the definition of the budget deficit that may be appropriate for our study. A first distinction is that between the consolidated balance and separate balances of Central and Local governments (in the following we refer to the consolidated version if the other is not indicated). It seems logical to refer to a negative value of General Government balance (i.e. to -(Government revenues - Government expenditures) as a deficit. By the Budget law, local budgets are to have zero balances. However, in Ukrainian practice, extra revenues of the local budgets are retained on special accounts and are not incorporated into consolidated deficit after end of reporting period. Therefore, General Government balance series seems to show periodic discrepancies with the Central government deficit financing, because of changes in government accounts balances and nonzero local budget balances. So, for some periods, GDEF-GBAL. A second distinction is between the National (Ministry of Finance of Ukraine) definition and the International (International Monetary Fund) definition of the deficit. The national definition of the budget deficit financing7 includes both internal and external financing as well as changes in government accounts balances. It is worth stressing that privatisation revenues are not considered a component of the financing of the deficit. From the national methodology viewpoint privatisation receipts are a Revenues side item. IMF definition covers external financing, financing via T-bills, changes in direct Central Bank credit to government, changes in government accounts balances. The set of government accounts differs from those included in the national definition. IMF considers changes of the balances of all extra budgetary funds incorporated in monetary statistics as part of the deficit definition8. National definition accounts only for income balances of budget entities while calculating the balance. A third distinction lies between accrual basis deficit (including arrears in payables to government entities of different levels) and cash basis data. The latter variant is adopted in our paper. Extra budgetary funds operations also might be taken into account, but due to legislative changes, it appears difficult to find reliable series. For example the State’s Pension Fund was possessing permanent deficits since 1994, but this quasi-fiscal balance was not incorporated into the consolidated budget, except in the year 1996. 7 See Act of Verkhovna Rada (Ukrainian Parliament) “On Structure of the Budget Classification”, July, 12, 1996, # 327 8 According to the IMF (1999) deficit consist of the following items: (1) total net treasury bill sales (total funds raised net of total interest repayment); (2) other net banking system credit to government (all non-treasury-bill financing extended to the budget by banks less all government deposits in the banking system); (3) receipts from privatisation; (4) all credit guaranteed by the government; (5) net proceeds from bonds issued by local authorities for the purpose of financing deficits of the consolidated budget; (6) net proceeds from bonds issued by the government to non-residents for deficit financing: (7) the difference between disbursements of foreign credits to the consolidated budget and the amortization of foreign credits by the consolidated budget; (8) the decline in government deposits in non-resident banks. 13 3.2 Dynamics The annual budget deficit to GDP ratio has been steadily declining (with the exception of 1997). It started in 1995 from the highly unbalanced point of 13,2% GDP and improved to less then 1,5% GDP in 1999. For the first 3 quarters of 2000 a budget surplus of 1% GDP was observed. Figure 2.

Calculations: ICPS Key determinants of the high level of budget deficit during 1993-1995 were extensive social security obligations, over-optimistic forecasts of both budget revenues and the macro environment. Though all these features did not cease to exist, the period of hyperinflation and high macroeconomic instability, unrealistic social security spending level were partly terminated in 1995. However, new possibilities for deficit financing, and unwillingness to cut public spending yielded a fallback to a 6,6% deficit in 1997. The political attempt to introduce an “Economic Growth” program, featuring tax reform, failed in late 1996, consequently producing a return to distorted public outlays, including subsidies to inefficient producers and social security overspending9. The average consolidated deficit level fall from 8,6% in the 1992-1995 to 3,8% of GDP in the stabilization episode of 1996-1998. The introduction of the new currency along with more tight monetary and foreign exchange policy lowered CPI inflation to 10,5% average in 1998. The financial crisis of 1998 influenced heavily the macroeconomic performance, creating macroeconomic instability. Forced rescheduling of government securities caused a final drying up of borrowing possibilities on private markets, both domestic and foreign. The suspension of external financing left the government no choice but to cut expenditures. The impounding of funds was used several times to meet current budget constraints. This "stabilizer" helped push the budget deficit towards 1,5 % GDP in 1999. More careful planning and pro-reform government seems to be taking the budget balance turn positive in the year 2000. 9 See HIID (1999). 14 Figure 3.

Calculations: ICPS 3.3 Financing The structure of the budget deficit financing was determined by different mechanisms available to authorities: external borrowing, direct financing by NBU credits, financing through T-bills market by private borrowing and by NBU purchases, then via secondary TBills market. 15 3.3.1 Direct NBU financing Unrealistic planning of budget revenues and significant government interference into the economy resulted in huge deficits of 1992-1995. The only source of financing was NBU credit to Ministry of Finance. For instance, external government borrowing in 1994 was covering less than 1% of the total. 3.3.2 External Financing The rehabilitation loan in the amount of 398 mln USD and EU bilateral agreement credit of 100 mln USD formed the major sources of external financing in 1995. Meanwhile we see gradual growth of external financing share, mainly by the World Bank (roughly 56%), EU and Japan in 1996. Table 1.

To compensate for a negative net disbursement of Tbills in the Fall of 1997, government was forced to search for funds on private markets. Two tranches of hryvnia denominated hedged securities were issued in December 1997 and August 1998. The December issue raised 750M UAH through Merrill Lynch and the August issue, roughly 330M UAH through ING Barings bank. Figure 5.

Calculations: ICPS To improve the situation further, the Finance Ministry has issued three groups of eurobonds. First, Ukraine received ECU 488M from Euro-denominated Eurobonds floated in ECU in March, 1998. In May of the same year a second tranche of deutsche mark-denominated threeyear Eurobonds generated DEM 259.35M. 16 External borrowing from official creditors has substantially contributed to financing in 1997, bringing to budget gross 600 mln USD, from the conditional World Bank loans, EU and other official creditors. The following year this borrowing decreased, resulting in a decline of the external financing share. Figure 6.

Calculations: ICPS 3.3.3 T-bills (OVDP) Financing The consequences of NBU direct financing had proved that the elimination of this mechanism was required to provide a sound commitment to lowering inflation. Ukraine’s T-bill market was created in the second quarter of 1995. The terms of circulation were 1-, 2-, 3-, 6-, 9-, 12and 18-months. The new bonds had fixed redemption date, and were structured as short-term and long-term securities. Most of the long-term securities have been purchased by the NBU. Figure 7.

Calculations: ICPS 17 In 1996 T-bills financing had reached the level of some 23% of the total. The discount version of T-bills was introduced in May, 1996. Also the secondary market was established. Access to Tbills was secured for foreign investors in the fall of 1996. Strong inflow of funds started. Figure 8.

Calculations: ICPS The performance of T-bills markett was relatively positive till mid-1997. After the Fall of 1997, foreigners began to withdraw their funds from this market and NBU purchases grew to be the majority share. In 1999, the current deficit was financed by means of domestic loans. Until the beginning of December 1999 the government issued OVDP (T-bills) totalling to 2048 mln Hrn. The growing volume of domestic financing is to a large extent being caused by the shortage of external sources of funds. Because of the crash of the domestic borrowing market in August 1998, the NBU had remained the major buyer. After the approval of law giving the National Bank a new status, direct purchases of T-bIlls for budget financing was legally prohibited, thus forcing NBU to transfer T-bills through the secondary market using Oschadbank as a primary buyer. 3.4 Inflation Performance As we have shown earlier, different types of financing affect prices in different ways. The direct financing mechanism theoretically influences the inflation rate via monetary base expansion. Tbills (domestic borrowing) financing induces effects by crowding out for Investment and Net Exports i.e. indirectly. The result may vary with the exchange rate policy. There is a choice of inflation indicators among consumer, producer prices or GDP deflator. CPI should react fast enough to changes in monetary policy. However, PPI seems to capture more of the exogenous shocks and imported inflation. The GDP deflator would be a good choice. Unfortunately, the latter is hard to estimate correctly, given the current availability of Ukrainian Statistics. 18 Figure 9.

Calculations: ICPS In evaluating the influence of deficit financing on inflation, the problem arises as to how to eliminate administrative and other exogenous shocks like the increases in household utilities in 1995-1998 and imported price shock of August 1998. The utility shock could be clearly seen from the utilities prices graph that shows kinks in January 1996, April 1996, July 1996 due to administrative tariff adjustments to eliminate subsidies to households. There was also an adjustment in April 1999. Figure 10.

Calculations: ICPS Until the begining of the crisis in August 1998, the central bank was able to neutralize the results of expansionary fiscal policy. Nevertheless the central bank's participation at the primary OVDPs auctions has changed its role from passive agent of the Ministry of Finance into active participant of the T-bills market. As we have mentioned in the theoretical section, the NBU sometimes is able to increase it’s T-bills holdings without holding a large effect on money aggregates.The growth of budgetary liabilities at the central bank has not had a direct inflationary consequences due to the negative sterilization policy followed by NBU until the middle of 1998. The central bank was channeling money to government (by new TBills purchases) and simultaneously made the conversion for that part of Tbills withdrawn by non-residents from the market, decreasing the level of foreign reserves and keeping the monetary base rather stable. 20 4. EMPIRICAL ANALYSIS 4.1 Methodology The purpose of this section is to empirically examine inflationary response to budget deficits, if any, when related variables, such as base money growth, exchange rate, domestic budget financing by NBU are taken into account. We test whether the price level is fiscal-dominantly determined10. We are also going to explore which part of the inflation variability is explained mostly by budget financing needs and which is influenced by other factors. Rejection of the fiscal-dominancy hypothesis may be only implicit, because of possible crossrelationships that neutralize the direct effect of budget financing through monetary measures. Similarly, finding that the government balance affects prices itself does not directly imply that the impact of the monetary factors is lower or absent. We chose the class of non-structural Vector Auto Regression (VAR) models for this analysis. Attempts to identify the components separately either in AR or structural specifications have failed in the sense that we obtain both poor econometric properties and weak economic inference. So we have tried to capture the mutual effect of variables associated with inflation to determine their net effect. It may be interesting to impose additional restrictions and consider structural VAR, but it is hard to identify whether fiscal or monetary disturbances in the Blanchard-Quah (1989) decomposition should be considered permanent11. Another candidate for the model specification, Vector Error Correction (VEC) model, was not supported by the cointegration tests12. Table 2. Data Used for the Estimation Mnemonics13 Description Unit Source CPI Consumer Price Index MBASE Monetary Base Mln UAH National Bank of Ukraine EXRATE Official Exchange Rate, period average UAH/ USD National Bank of Ukraine MA_CLG Net claims on Government Mln. UAH International Financial Statistics GBAL General Government Balance Mln UAH State Treasury State Statistics Committee We have examined specifications with the following features: The price level tends to be the most endogenous variable while the others are considered more exogenous. The last exogenous, and hopefully the most powerful, is the fiscal deficit series or its transformations; The specification includes 5 variables: consumer prices (CPI), exchange rate (EXRATE), monetary base (MBASE), NBU net credit to government (MA_CLG), and budget balance 10 In contrast, the money-dominant regime would show that the inflation depends only on money supply, so it is the monetary phenomena only. 11 In other words, it is near impossible to find out which shocks are permanent, and which are temporary. 12 We still expect some long-run relationship between money and prices to hold. This is to be the subject for a closer examination, but is beyond the scope of this paper. 13 In addition, the following mnemonics are used: LOG denotes logarithm of the variable, HF denotes HPF filter, SA denotes Seasonally Adjusted by X-11.2 series, D denotes the first different, D(X,2) denotes the first difference. 21 itself (GBAL). The ordering of the variables is important in VAR analysis, so we sort out variables as follows: CPI, MBASE, EXRATE, MA_CLG, GBAL; The general VAR specification is: n pt t Ai pt i BX t t i 1 where pt is the transformed variables vector , pt-i , are the lagged variables vectors, Xt are the explanatory variables, matrices Ai, B to be estimated. We have examined the sample of monthly data for 1995:1- 2000:6. The results of quarterly regressions have shown significant loss in explanatory power, so we remained with the volatile but more responsive monthly frequency. Table 2 reports the sources of the data, whereas summary statistics of the original and transformed VAR series are presented in Appendix 1. Government balance is the general government balance, using national definition, and is negative for a deficit. 4.2 Regression Results According to the Augmented Dickey-Fuller test results (Appendix 2), prices, monetary aggregates, credit to government and exchange rate appear to be I(1) processes with trend and drift, though the government balance seems to be I(0) i.e. stationary in levels. Thus we differentiated once all series except GBAL, which is left in levels. Pairwise Granger causality tests (Granger, 1969) are shown in Appendix 3. It becomes clear NBU financing may directly affect the prices. However, we have not enough evidence to reject the null hypothesis of no causality from budget balance to prices. The regression results are shown in Appendix 4, whereas Appendix 7 covers the impulse response functions (IRF), a short-run dynamic one and a cumulative one for the steady state14, and the variance decomposition. Appendix 5 assures that stability of the underlying AR scheme in VAR holds. All roots lie inside the unit circle that guarantees the lag polynomial stability. We chose the lag length of 2 after the concurrent testing and examination of various cross-correlation relationships (see Appendix 6). The discovered VAR scheme is dynamically stable and rapidly converge to steady state. The GBAL equation is the weakest part of the model, however not weak enough to ignore GBAL effect. Some of the regressors are correlated, so it’s hard to analyze the corresponding tstatistics. Nevertheless, the estimation method generates consistent unbiased estimates for the model coefficients. Chow forecast test couldn’t reject the hypothesis of no structural break for financial crisis 1998. The largest cumulative effect on inflation rate has the inflation itself. A 1% increase in inflation generates 2.5% more inflation over the next year (2% over the 6 months). Inflationary impacts of the monetization of the budget deficit and the budget deficit itself are of same magnitude. Dynamic cumulative elasticity15 of the price level to the NBU claims to government equals 0.4. A 1% increase in the stock of the credit to government leads to 0.4% of inflation over the year. The biggest impact is on 3-5 month after the shock. 14 The interpretation of the impulse response functions (IRF) graphs is that they demonstrate dynamic responses of the inflation change to innovations in other variables. 15 The dynamic semi-log elasticity (Pindyk and Rubienfeld, 1998) is calculated following the formula EYX ( ) X t Yt Yt Yt X t . 22 On average, an increase in the deficit of 1% GDP16 leads to 0.38% inflation over the next year. As the average monthly GDP and the stock of NBU credit to government are very close amounts, same percentage change in both leads to roughly equal inflationary response. Somewhat surprisingly, regression results show exchange rate and monetary base dynamics have very low, if any, influence on prices17. We tend to explain this finding by supposedly the same monetary nature of the monetary base, the claims to government, and the exchange rate. Thus, the model finds the most linked variable, diminishing the marginal contribution of the others. Forecast-error decomposition illustrates that steady state configuration of CPI inflation variance is distributed 10% due to growth of the NBU credit. Exchange rate and budget balance variations yield approximately 3% explanation to inflation each. The monetary base growth explains less than 1% of the inflation variability. 4.3 Policy Implications The empirical estimation demonstrates the existence of complicated links between fiscal deficits, money, and inflation in Ukraine. We could hardly expect to find clear and linear structural coefficients that would provide policymakers with clear-cut recipes in the economy undergoing structural changes. At the same time, the VAR analysis leads us to the tentative economic policy implications: although more possibilities, not just monetization, emerged to finance fiscal deficit in the second half of the 1990s (through T-bills market and from external sources), the fiscal imbalance still has a substantial inflationary impact. In our opinion, it suggests a lack of credibility in government debt management. Even if the government managed to attract funds from the public, economic agents do not trust the government would not be forced to reverse to monetization. Therefore the price level starts to grow in expectation of later monetization not far away. Financial crisis of 1998, when T-bills market fell, is the strongest example. It is crucial now to restore credibility to the government securities, for deficit to be less inflationary; cutting budget deficit is disinflationary, even more so when monetization share is falling. In the extreme case, a monthly 1% GDP decrease in budget deficit, all of which was previously monetized, subtracts 0.8% from annual inflation. If a non-monetized share of the deficit is eliminated, annual inflation is lowered by 0.4%; the monetary policy conduct in Ukraine largely depends a lot on a stance of the fiscal policy. The model suggests that in order to neutralize the inflationary effect of the fiscal expansion, the NBU need to decrease its credit to the government. However, previous experience shows, that it is hardly possible. inflationary inertia has a strong disinflationary potential. Once authorities manage to cut a monthly inflation rate by one 1%, the benefit is tripled over the year. Finally, a note of caution should be made. The model we examined in this paper is not universal. For example, it fails to incorporate possible influence of real sector of the economy. Various exogenous shocks, like discrete administrative price increases certainly lower the explanatory power of the model. Therefore, as a forecasting tool the model might be used very cautiously. 16 To get the dynamic impact multiplier in terms of GDP, we multiplied the coefficient from the model by an average monthly GDP. The average monthly GDP over the period 1995:1-2000:6 was 8545 mln UAH. The coefficient, obtained directly from the model, answers the question: how disinflationary is a 1 mln UAH cut of the deficit? 17 The exchange rate change seems to be highly inflationary during the first 3 months after the shock, but later on it is being compensated. 23 5. CONCLUSIONS The purpose of this paper was to evaluate the importance of budget deficit for inflation in Ukraine in the second half of the 1990s. We find that fiscal imbalance, apart from other, purely monetary factors, does affect the level of inflation determination. A monthly decrease of budget deficit by 1%GDP, all of which was previously monetized, leads to decrease of annual inflation by 0.8%. If a non-monetized part of the deficit is eliminated, annual inflation is lowered by 0.4%. Among the monetary factors, the monetization of the deficit seems to be the most inflationary. The dynamics of the National Bank’s claims to government (monetization) appear to be more tightly linked to the inflation than the monetary base and the exchange rate. Since the budget policy remains an important inflationary factor, the room for an independent monetary policy remains limited. 24 6.
