INSTITUTE OF BANKERS IN MALAWI ECONOMIC ENVIRONMENT (DIPLOMA IN BANKING) MAY 2011 SOLUTIONS BY: KONDWANI MLILIMA MODEL ANSWERS SECTION A: QUESTION 1 (a) Motive 1 (transaction demand) 1 o Held as medium of exchange 1 o To facilitate payments o Demand depends on total value of transactions 1 o Demand depends on level of income Motive 2 (precautionary demand) 1 o Held as medium of exchange o Allows for unpredictable transactions 1 o A function of national income 1 Motive 3 (speculative demand) 1 o Related to the ‘store of value’ function of money 1 o Affected by interest rate, which is the opportunity cost of holding cash versus interestbearing assets 1 o The higher the interest rate the lower the demand (b) Labour is a homogenous factor of production The quantities of the other factors of production are held constant There is perfect competition in both the labour market and goods market 2 2 2 QUESTION 2 (3 marks each) (a) (i) R&D: issue of patents protects some firms 3 (ii) Tariffs: protect domestic firms 3 (iii) Inflation: differences in price increases over time matters 3 (iv) Exchange rate: the movements alter the price of either imports or exports and affects competitiveness 3 1 (i) Factor endowment: quantity and quality of inputs matter 3 QUESTION 3 a) (b) HDI stands for Human Development Index 1 HPI stands for Human Poverty Index HDI is based on the following development indicators: education, income and life expectancy 2 HPI is based on the following human life factors: longevity, knowledge, economic provisioning and social inclusion 2 GDP includes defensive expenditures e.g. those aimed at mitigating negative externalities GDP does not include non-marketed output e.g. housework GDP does not include illegal businesses or some transactions for the informal sector GDP does not account for externalities – positive or negative GDP does not measure economic inequality 2 2 2 2 2 QUESTION 4 (a) Consumption by one person does not reduce amount available to others Do not have opportunity cost 1 1 (b) a family member does not sell a service when working for his’er own household 1 the output is non-marketed; so, it does not form part of GDP 1 on the other hand, the gardener is formally employed and gets paid for working; so, his’er output is accounted for in GDP 1 (c) A command economy is where all key economic decisions are made by government while in a mixed economy both elements of free enterprise markets and command economy come into play 2 Government enterprises are privatised 2 Markets are deregulated to allow more competition 2 Production subsidies are phased out 2 The economy opens up to FDI 2 2 SECTION B QUESTION 5 (a) Raise government spending Cut taxes Cut interest rates Increase money supply 1 1 1 1 (b) Accommodation: central bank lending to commercial banks whereby the latter are short of liquidity 2 Open market operations: it is done via sale or purchase of financial securities (e.g. treasury bills) in order to reduce or raise money supply and influence interest rates 2 Reserve asset requirements: banks are required by central bank as a matter of policy to keep a certain proportion of its liabilities at the central bank (or on its own but in liquid assets) 2 Credit ceilings: a law is passed that prohibits banks from exceeding a certain level of outstanding loans to the public 2 Deposit rate control: here financial institutions are advised as to the rate they can pay on deposits 2 Moral suasion: central bank persuades commercial banks to behave in an expected manner to achieve policy objectives 2 (c) Classicals: government should be allowed to play only the wealth distribution role government should only deal with market failures government should not run businesses government businesses are really owned by nobody government businesses do not embrace competitiveness so, they support privatisation Socialists: Privatisation leads to profiteering This happens at the expense of workers, quality of service, and society as a whole National assets are controlled by foreigners 1 1 1 1 1 1 1 2 1 3 QUESTION 6 SRAS3 Price SRAS1 P3 10 P2 P1 AD1 Y1 Y3 Y2 AD2 Real output Multiplier effect explains how a change in AD will have far-reaching impact on equilibrium national income 2 When there is a trigger e.g. a cut in taxes or increased government expenditure, companies will need to increase production to meet the extra demand 2 On the graph, this is the movement from AD1 to AD2, which increases output from Y1 to Y2 and the price level from P1 to P2 2 But if supply is inelastic (SRAS3), output increase will not reach Y2 but Y3, thus only aggravate inflation (new price level will be P3) 2 Also with increased demand the central bank may raise interest rates, thus curtail borrowing by firms to expand or increase supply 2 QUESTION 7 (a) Transactions with foreign countries: Money supply increases with increases in foreign reserves 1 So, exports and capital inflows raise money supply 1 So, imports and capital outflows reduce money supply 1 Government transactions: Government deposits at the central bank or sale of Treasury bills for expenditure financing have the same impact of reducing money supply because liquidity is withdrawn from circulation 1 The converse is true with the purchase of Treasury bills 1 4 (b) LRAS Price P2 P1 6 AS2 AD AS1 Q2 Q1 Qf Income Cost-push inflation occurs when firms increase prices to protect margins after facing a rise in the cost of production 2 When production costs soar, the supply curve shifts inward from AS1 to AS2 and the price goes up to P2 from P1 2 This causes aggregate demand to fall to Q2 from Q1 2 Causes: o Rising cost of imports or imported inflation 1 o Rising labour costs 1 o Higher indirect taxes 1 QUESTION 8 (a) Narrow money or M1 The components are: currency in circulation and demand deposits 1 2 (b) Advantages: convenient and more liquid Disadvantage: loses purchasing power during high inflation periods 1 1 (c) Consumption Consumption 5 45 Real disposable Income 5 The standard Keynesian consumption function is presented as: C = a + cYd (where C is consumption and Yd is disposable income) 2 Consumer spending rises with income 2 Rise in spending is at a rate below that of income 2 ‘a’ is autonomous expenditure, where real disposable income is zero but one still consumes out of savings (i.e. dis-saving). It is the intercept. 2 ‘c’ is the marginal propensity to consume, which falls between 0 and 1. It is the slope of the consumption function 2 – THE END – 6
