The Impact of Free Trade Agreements on Foreign Direct Investment Yong Joon Jang Indiana University Department of Economics Apr 6, 2007 1 Abstract 2 I. Introduction The first Regional Trade Agreement (RTA), EC (Treaty of Rome) came into being in 1958. Ever since then about 220 RTAs have been signed. The year of 1992 witnessed a sharp increase in the growth rate in the number of RTAs. After that RTAs have kept increasing at a steady rate of 16%. (See Figure 1). According to WTO, RTA can be classified into the following four kinds of treaties. The first one is Free Trade Agreement (FTA), which is the lowest level of RTA. With FTA, a country should reduce or eliminate a tariff for member countries but impose a different tariff on non-member countries. The typical example is North American Free Trade Agreement (NAFTA). Under NAFTA, there are no tariffs for trades among Canada, Mexico and U.S., but each country imposes different tariffs on non-member countries. The second one is Customs Union (CU). Under CU, there is no tariff between member countries, but each member country imposes a common tariff on non-member countries. Mercado Comun del Cono Sur (MERCOSUR) is one example. The third one is Common Market. Under Common Market, member countries carry out common monetary and fiscal policies. One example is European Community (EC). The last one is Single Market, which achieves a political and economic unity with common currency and common assembly. One example is Europe Union (EU). I will focus on the lowest level of RTA, FTA in this paper. As the other three RTAs involve much more restrictions, it would be rather complicated to analyze their impact on economic activities. Foreign Direct Investment (FDI) has also increased over the past two decades. The total amount of FDI increased from 7.4% of the world GDP in 1982 to 22.1% in 3 2002 (See Figure 2). (I will compare the FDI growth between developed-developing countries and between developed-developed with the figure in my future draft) Obviously descriptive data shows that both the number of FTA and amount of FDI increased in the past twenty years. How does FTA affect the economic activities in the member countries? In particular, what effects does FTA have on foreign direct investment (FDI)? Previous research has found a positive effect of FTA on FDI between developed countries and less developed countries. But is this effect always positive between different country-pairs? What will happen when host and parent countries are both developed? Unfortunately no research has ever addressed this question. The objective of this paper is to fill in this blank in research. I attempt to empirically analyze the impact of FTA on FDI among 23 OECD countries from 1982 to 2004 using the Knowledge-Capital model as my theoretical framework. II. Relationship between FTA and FDI Recently many theoretical and empirical works in International trade have focused on motives for FDI of Multinational enterprises (MNEs). These works are divided into three main categories: the horizontal motivations (Markusen, 1984; Markusen & Venables, 1998), the vertical motivations (Helpman, 1984; Helpman & Krugman, 1985) and the Knowledge-Capital model (Markusen & Maskus, 2001) that combines both the horizontal and vertical models. Horizontal FDI & Vertical FDI Horizontal FDI is designed to place production close to consumers and thereby avoid trade costs. Multinationals have a plant and a headquarters in a home country (or 4 source country) and other plants in each host country. So each production facility supplies each individual market. However, there exists a trade-off between realizing economies of scale at the firm level and using tariff-jumping strategies. The main factors which affect the incentives for horizontal FDI are trade cost and market size of host country. When trade costs in host country rise, exporters to this country would encounter a higher marginal cost. Hence, they have higher incentive to build a plant in the host country and sell their products directly. If the market size of the host country expands, firms would have more incentives to build production facility there because the associated fixed cost would be covered by the revenue generated. Consequently horizontal FDI will increase as trade cost and market size in host country increase. However, if trade costs decreases, then multinationals with higher fixed costs may concentrate their activity in one country and develop trade flows with host countries rather than open plants in each country (Yeyati, Stein and Daude, 2003 and Lesher and Miroudot, 2006) On the other hand, vertical FDI is driven by the desire to carry out unskilled-labor intensive production activities in locations with relatively abundant unskilled labor. Multinationals have a headquarters in a home country and a plant in a host country. In this case, a home country is relatively abundant in skilled labor and a host country is relatively abundant in unskilled labor. After producing goods in a host country, firms with vertical FDI should import them to the home country to supply their home consumers. 5 The main factors which affect the intensives for vertical FDI are trade costs and skill difference between home and host countries. As trade cost increases in host country, firms with vertical FDI will have to import goods from the host country at a higher cost. However, as the skill difference between home and host countries increases, relative wage for low skilled labor will decrease. So firms would have more incentives to produce their goods with lower production costs in the host country. Consequently, vertical FDI will increase as trade costs decrease and skill difference increases (Yeyati, Stein and Daude, 2003 and Lesher and Miroudot, 2006) Knowledge-Capital model Markusen et al. (1996) and Markusen (1997) built the Knowledge-Capital model with two countries, two factors, and two goods. In this setup, they compare the incentives for three different types of firms: horizontal firms with a plant in each country and a headquarters in the home country, vertical firms with a plant in the host country and a headquarters in the home country; and national firms with a plant and a headquarters in the home country. Markusen et al. (1996) analyzed various factors that affect FDI, including market size, skill difference, distance between two countries, trade cost and their intersections. I will pay more attention to the relationship between trade costs and FDI in my paper (I will fully explain this model in my future draft). FTA & FDI 6 Carr et al. (2001) empirically test the Knowledge-Capital model. Their results show that trade costs have positive effects on FDI when there exists a small skill difference between parent and host countries but negative effects when the difference is large. Since they use affiliates’ sales in host country to proxy FDI, insufficient information exists to distinguish vertical FDI from horizontal FDI. However, their results seem to show that in the case of small skill difference between parent and host countries, when trade cost rises, the increase in horizontal FDI will dominate the decrease in vertical FDI and vice versa when the skills difference is big. Also, this may imply that the decrease in horizontal FDI will dominate the increase in vertical FDI in case of small skill difference between parent and host countries when trade cost falls and vice versa when the skills difference is big. This is my hypothesis for the effects of decreased trade costs on FDI in an OECD - OECD countrypair and an OECD - non-OECD country-pair. In this paper, I want to test these relationships by defining decreased trade costs as FTA. As is well known, FTA is made to reduce trade cost. That is, when two countries agree to form FTA, trade cost would fall or diminish between them. As a result, firms with vertical FDI will benefit from this and hence have more incentive to increase vertical FDI. On the other hand, there will be less tariff-jumping incentive for horizontal FDI. Vertical FDI dominates horizontal FDI in countries where skill difference is large. Hence FTA should have a positive effect on FDI where member countries have large different skill levels. 7 However, the reduced trade cost will discourage firms from building plants with high sunk cost in host country. In other words, firms with horizontal FDI will have more benefit from economic of scales rather than tariff-jumping strategies. This leads to a decrease in horizontal FDI. Since horizontal FDI dominates vertical FDI in countries where skill difference is small, FTA should have a negative effect on FDI with similar skill levels. This is exactly my hypothesis – When the skill difference between parent and host countries is small, FTA is going to have a negative impact on FDI and vice versa1. III. Literature Review All the previous empirical works on the relationship between FTA and FDI are summarized and compared in Table 1. They all find RTA to have positive effects on FDI 2 . Most authors use the gravity model. (I will expand this Table 1 into a detailed literature review later). I will follow the previous scholars and use the Knowledge-Capital model. By considering trade costs and skill difference between member countries at the same time, the Knowledge-Capital model provides a good framework to analyze the effects of FTA on separated FDI: Horizontal FDI and vertical FDI. My paper differs from the previous works in the following important ways: First, unlike the previous empirical works, I will consider not only the impact of FTA on FDI among member countries, but also the impact of FTA on FDI from non-member countries to member countries. The first effect is called “intra- regional effect”. I expect 1 In this paper, I analyze the effect of FTA only on the intra-regional FDI. In other words, I exclude the effects of FTA on FDI from non-member countries in the main regression. Yeyati et al. (2003) define the changes of FDI from non-member countries as redistributive effects, FDI diversion and FDI dilution. In sensitivity analysis, I will control for this effect. 2 Some authors defined RTA as Regional Integration (RI) or (multilateral) FTA. 8 FTA to affect horizontal FDI negatively and vertical FDI positively among member countries. The second is called “extra-regional effect”. I will consider the second one after the first draft of the third-year paper. I want to examine if this “extra-effect” is positive or negative. Second, all the previous works use “multilateral” RTA as a key independent variable, while the dependent variable is “bilateral” FDI. This would be problematic because there exists redistributive effects among member countries and the bilateral FDI cannot control for this effect. In this paper, I consider only the bilateral FTA between 1982 and 2004. There is no bilateral FTA before 1982. Third, previous studies dealing with the relationship between FDI and FTA usually assume all independent variables to be exogenous and neglect the possible endogeneity problem. For example, a higher FDI between two countries can affect their economic growth positively. So I introduce GMM to this area to solve the endogeneity problem. Finally, I consider the dynamic specifications of FTA on FDI. In the previous study, only Velde and Bezemer (2004) conducted time series analysis. They studied the effects of specific investment-related provisions in RTAs on FDI from US and UK to developing countries from 1980 to 2001. But since many gaps exist in their data, they confined their analysis to including time dummies and using “error correction form”. In my paper, I will use First Difference estimator, ECM estimator, and DID (Difference-indifference) estimator. IV. Model Specification and Econometric Methodology 9 To analyze the impact of bilateral FTA on bilateral FDI, I followed Carr et al. (2001) and Egger and Pfaffermayr (2004) in setting up my key regression models, which are fixed-effects OLS. Carr et al. (2001) empirically tested the Knowledge-Capital model by estimating how FDI is influenced by country characteristics including economic sizes, relative endowment differences, trade and investment costs, and certain interaction among these variables. Egger & Pfaffermayr (2004) added Bilateral Investment Treaties (BIT) to Carr et al. (2001)’s regression model and changed the dependent variable into bilateral FDI. They found a significant positive relationship between BIT and FDI, because BITs would reduce the costs of investing abroad, including risk premium. Equation (1) shows my major regression model. I use outward FDI of each OECD country to another country ( Fijt ) as the dependent variable. For the independent variables, I basically follow what Carr et al (2001) and Egger & Pfaffermayr (2004) used. I replace BIT with RTA and tertiary school enrollment share in Egger & Pfaffermayr (2004) with per capita GDP (“Percapita GDP”) for relative endowment differences. I add a new variable trade openness (“OPEN”) to control for the effects of trade on FDI. Please see table 2 for a detailed explanation of the dependent and independent variables in my model. Fijt 1 GDPijt 2 SIMI ijt 3 SK ijt 4 DISTij SK ijt 5 GDPijt SK ijt 6 FTAijt 7 FTAijt DISTij ij t ijt Table 3 summarizes the expected signs of the variables on horizontal FDI in this paper. Below is a rationale for my expectations. (1) 10 First, I expect FTAijt to have a negative effect on Fijt in OECD – OECD country pairs (intra OECD) and a positive effect in OECD – non-OECD country pair (extra OECD). Carr et al.(2001) shows that as trade costs in host country increase, horizontal FDI tends to increase whereas vertical FDI tends to decrease. To avoid increased trade cost in host country, exporters from parent country are likely to build plant in host country and sell their goods there. Thus Horizontal FDI increases. However, vertical FDI tends to decrease as parent country has to encounter an increased cost when importing from host country. Carr et al. (2001) show that horizontal FDI dominates vertical FDI when skill difference between home and host countries is small. Egger & pfaffermayr (2004) show that skill difference between OECD countries is relatively much smaller than other countries3. Hence, I expect horizontal FDI to dominate vertical FDI in the intra OECD dataset and vertical FDI to dominate horizontal FDI in the extra OECD dataset. As FTA eliminates various trade barriers such as tariff, and horizontal FDI dominates vertical FDI among developed countries, the coefficient sign of FTAijt should be negative in the intra OECD dataset. However, as vertical FDI dominates horizontal FDI among developed-undeveloped county-pair, the coefficient sign of FTAijt should be positive in the extra OECD dataset. As a result, the coefficient sign of FTAijt is ambiguous in the whole dataset. Second, according to Carr et al.(2001), as market size of host country increases, exporters to this country acquire more consumers but simultaneously face higher marginal trade costs. So they have more incentive to build a production plant in the host 3 In my dataset, skill difference in intra OECD is much smaller than in extra OECD. Please see Table 6 11 market, even though they have to pay the big fixed costs. Therefore, market sizes ( GDPijt ) have positive effects on horizontal FDI. I expect the coefficient of GDP ijt to be positive in intra OECD. However, vertical FDI is not related to market size. As there still exists horizontal FDI in extra OECD, the coefficient of Overall, I expect of the coefficient of GDP ijt GDP ijt would be also positive in extra OECD. to be positive in the all the country-pairs in the dataset. Third, by simulation of the Knowledge-Capital model, Carr et al. (2001) show that moderate difference in sizes of both parent and host countries encourage MNEs to run a plant in a host market. Therefore, similarity in market sizes of parent and host countries ( SIMI ijt ) have positive effects on horizontal FDI. Hence, I expect the coefficients of SIMI ijt to be positive in intra OECD. Again, as vertical FDI is not related to market size and horizontal FDI still exist in extra OECD, the coefficient of SIMI ijt would be also positive in extra OECD. Overall, the coefficient of SIMI ijt would be positive in all the country-pairs in the dataset. Fourth, as Markusen and Venables (2000) show that dissimilarity in relative endowments reduces horizontal FDI, SK ijt should be negatively related to FDI in intra OECD country. On the other hand, as vertical FDI is driven by the desire to carry out unskilled-labor intensive production activities in location with relatively abundant unskilled labor, the relative skilled-labor difference between parent and host countries ( SK ijt ) should affect vertical FDI positively. In other words, the coefficient of SK ijt 12 is positive in extra OECD as vertical FDI dominates horizontal FDI. As a result, the coefficient sign of SK ijt is ambiguous in all the country pairs in the dataset. Fifth, Egger et al.(2004) show that the difference in the skilled to unskilled labor endowment supports vertical FDI to a lesser extent if the bilateral distance is large. So DISTij SK ijt would be negative in extra OECD. However, the effect of this intersection term of the skilled-labor difference and the distance between two countries ( DISTij SK ijt ) is positive on horizontal FDI. As horizontal FDI is expected to dominate vertical FDI among OECD countries, the coefficient sign of DISTij SK ijt would be positive in intra OECD. Overall, the coefficient sign of DISTij SK ijt would be ambiguous in the whole country dataset. Sixth, the variable GDPijt SK ijt represents the simultaneous effects of skill difference and market size of both parent and host countries on FDI. Egger et al. (2004) shows that this affects horizontal FDI negatively and vertical FDI positively. So the coefficients of GDP ijt SK ijt would be negative in intra OECD and positive in extra OECD. Overall, the coefficient sign of GDP ijt SK ijt would be ambiguous in the whole OECD dataset. Finally, I obtain trade openness ( OPEN jt ) by dividing the sum of exports and imports by current GDP, i.e. the total trade as a percentage of GDP. As vertical FDI is positively related to the quantity of exports in host and imports in home countries, the effect of trade openness of host country is positive on vertical FDI. However, horizontal 13 FDI has little to do with the volume of trade and thereby is not affected by trade openness. Hence, I expect that the coefficient of OPEN jt is always positive. I use Pooled OLS, Between estimator, Within (fixed effect) estimator, Random effect-GLS estimator and Random effect-MLE estimator for the main regression. All regressions are based on country-fixed effect.4 V. Data Table 4 lists the variables and their respective sources. My database consists of 7053 observations of 23 OECD countries from 1982 to 2004. I dropped 7 countries from a total of 30 OECD countries because they do not have bilateral FDI data. In my sample there are 13 OECD home countries, 23 OECD host countries and 14 non-OECD host countries (See Table 5). So there exist 468 country-pairs from 286 intra OECD countrypairs and 182 extra OECD country-pairs. Table 6 shows the respective bilateral free trade agreements and the member countries between 1982 and 2004. Before 1982, only multilateral FTAs existed including EC, EU and EFTA. To avoid the problem of redistributive effect that I mentioned in Section 3, I include the bilateral FTAs between 1982 and 2004 in the dataset of RTA. But I also include FTAs between a single country and several other countries such as ECTurkey and EFTA-Mexico, because they have bilateral characteristics. In other words, the FTA between EC-Turkey functions like bilateral FTA between anyone of the EC countries and Turkey, for example, UK and Turkey. Table 7 reports summary statistics for the key variables. I found them similar to the values obtained by Egger et al. (2004). The mean value of skill difference ( SK ijt ) in 4 The results from year-fixed effect are that all the coefficients of FTA are insignificant. 14 intra OECD is 0.58 much lower than 2.01 in extra OECD. This is congruent to my expectation, which is that the skill difference among OECD countries should be relatively small. VI. Results Full Sample Table 8 reports the regression results for Pooled OLS, Between estimator, Within (fixed effect) estimator, Random effect-GLS estimator and Random effect-MLE estimator in the entire dataset. The coefficient estimates of GDP ijt , SIMI ijt and OPEN jt are statistically significant with expected signs in all regressions except for Between estimator. The coefficient estimates of FTAijt is negative and statistically significant in Within estimator, RE-GLS estimator and RE-MLE estimator regressions. This indicates a negative effect of FTAijt on FDI among all the country pairs from 1982 to 2004. The coefficient estimate of FTAijt is positive but statistically insignificant in Pooled OLS and Between estimator regressions. Since the dependent variable is logarithm and FTAijt is a dummy variable, I need recalculate the value of the coefficient to get the effect of implementing FTA. I can use the formula, 100 exp( 6 0.5 Var ( 6 ) 1) , proposed by Kenney (1981) and van Garderen and Shah (2002). As a result, the impact of RTA is -68.92% on FDI in all the country pairs between 1982 and 2004 on average using Within estimator, RE-GLS estimator and RE-MLE estimator. 15 Among all these estimates, I trust Within estimator most. First, all independent variables are time-varying. Second, R 2 is highest among all the models. Finally, I conducted the Hausman-test for whether Fixed or Random estimator is appropriate. The result shows that the null hypothesis was rejected at 1% significant level. So Fixed effects are present. Sub-Sample To analyze why bilateral FTA affects FDI negatively, I divide the whole sample into two sub-samples: intra OECD and extra OECD. I obtained Within estimator, REGLS estimator and RE-MLE for the two sub-samples. Pooled OLS is not appropriate here as the errors for a country-pair are almost positively correlated over the years. So the coefficient estimator in Pooled OLS would be inconsistent if Within estimator is appropriate. Moreover, the Between estimator is inconsistent as the independent variables are time-varying. Table 9 shows the regression results of Within estimator, RE-GLS and RE-MLE regressions in intra OECD and extra OECD sub-samples. The coefficient estimates of GDP ijt , SIMI ijt and OPEN jt are statistically significant with expected signs in all regressions for both intra OECD and extra OECD sub-samples. All values of GDP ijt and SIMI ijt in intra OECD sub-sample are much greater than those in extra OECD subsample, indicating the effect of market size is larger for intra OECD sub-sample than for extra OECD sub-sample. Since horizontal FDI has a positive relationship with market size while vertical FDI does not related to, I expect horizontal FDI among intra OECD countries to be greater than that among extra OECD countries. 16 The coefficient estimates of SK ijt has expected signs but insignificant in all regressions for both intra OECD and extra OECD sub-samples. This might lend some support to the assertion that horizontal FDI dominates vertical FDI in intra OECD countries where skill difference is relatively small and vice versa in extra OECD countries where skill difference is relatively big . The coefficient estimates of FTAijt and DISTij FTAijt are statistically significant with the expected negative signs in all three regressions for intra OECD. The coefficient estimate of FTAijt in extra OECD is statistically significant with the expected positive sign only in Within estimator regression. Actually the model of Within estimator has the highest R 2 among the three for both sub-samples, indicating this model is most appropriate to use in this study. Hence, the sub-sample regression results suggest that FTA affects FDI negatively in intra OECD county-pairs but positively in extra OECD country-pairs. The Within estimator of FTA is -3.451 for intra OECD country-pairs and 3.635 for extra OECD country-pair. As there are much more country pairs for intra OECD (4589) than those in extra OECD (2464), the Within estimator of FTA is negative (2.599) in the full sample. This shows that the negative effects of FTAijt comes mainly from intra OECD country-pairs where horizontal FDI dominates vertical FDI. (I am still looking for the reason why there is the negative effect of FTA on FDI in the full sample.) VII. Sensitivity analysis Endogeneity problem The fixed-effects estimators assume all the independent variables to be exogenous. 17 Our key variable FTA, however, may be endogenous. The more FDI, the more trade activities will result between the two countries. Consequently, this increased trade across the border may increase the demand to get rid of the existing trade barriers and to form FTA. Hence, FTA can be an endogenous variable. However, no one has considered the possibility of FDI to affect FTA. Meanwhile, all the other independent variables can be endogenous. Since they are measured in the same year as the dependent variable FDI, it is possible that they may either be correlated with the error term. Moreover, independent variables such as GDP and per-capita GDP may be affected by the dependent variable FDI. Therefore, endogeneity seems to be a serious problem that would make the fixedeffects estimators inconsistent. To solve the endogeneity problem, I set up two-step GMM models. ( I am still trying this estimation.) Time series analysis 1) Unit root test for panel data To test whether outward FDI is non-stationary, I first conducted two unit-root tests for outward FDI: LLC test (Levin, Lin and Chu, 2002) and IPS test (Im, Pesaran and Shin, 1995). Table-10 shows the results from the two tests. Although the results from LLC test show outward FDI is stationary for most country-pairs, we cannot determine whether non-stationarity exists from IPS test. The important assumption of the LLC test is the independence of individuals, that is, the independence of country-pairs in my case. So I checked if there is any 18 relationship across country-pairs in the same home country by analyzing the scatter plot of two coefficients on AR1 and AR2. The regression equation is as follows: Fijt 1ij Fijt1 2ij Fijt 2 ijt . The results from the scatter plot show that most of points on the plots are located near or just below the line 1 2 1 , which is the line corresponding to unit root AR(2) models. Given the well-established fact that standard unit root tests tend to be downward biased for small T, evidence in favor of unit roots in FDI is pretty strong. Hence, if I have to choose a single hypothesis that would provide a better description of outward FDI for the majority of country pairs, I will choose the unit root I(1) process. 2) First-difference estimator As outward FDI is non-stationary process, I estimate the first difference estimator as follows: dFijt 1d GDPijt 2 dSIMI ijt 3 d SK ijt 4 d ( DISTij SK ijt ) 5 d ( GDPijt SK ijt ) 6 dFTAijt 7 d ( FTAijt DISTij ) (t t 1 ) d ijt Table-11 shows the results from the first difference estimator with the full sample, intra OECD and extra OECD. The coefficient estimates of d GDPijt and dSIMI ijt are still positive and statistically significant in all the models. Meanwhile, the values of d GDPijt and dSIMI ijt in intra OECD are greater than those in in extra OECD, indicating the first differenced market size is larger for intra OECD sub-sample than for extra OECD subsample. Since horizontal FDI has a positive relationship with market size while vertical (2) 19 FDI does not related to, I expect horizontal FDI among intra OECD countries to be greater than that among extra OECD countries. The coefficient of dOPEN jt is positive and statistically significant for the full sample and the sub-sample of extra OECD. All the coefficient of dFTAijt is positive but statistically significant only in extra OECD at 10% significant level. (I am still looking for the appropriate first-difference estimator with a dummy variable. One candidate is ECM regression, which I will try later.) 3) Difference-in-differences estimator (DID estimator) I estimated the Difference-in-difference by regressing the following equation; F 1 Dt 2 fta 3 Dt fta t 1 if year t 1 if fta has been forced between two countries , where Dt & fta 0 otherwise 0 otherwise Thus, Dit ftai = 1 if FTA has been forced between countries in the post periods. (i.e. Dt represents whether F is in the post period.) The coefficient, 3 , on Dt fta is the Difference-in-difference estimator. (Trivedi (2004), p.891) Since the sample periods are from 1982 to 2004, I estimated the Difference-indifference by each year between 1983 and 2004. Table-12 shows the estimate results in the full sample. 20 The coefficient estimates for Dt fta are statistically significant only in 1983, 1998, 1999, 2000 and 2001. However, the DID estimator in 1983 is positive, while those in each period between 1998 and 2001 are negative. Among the significant values in Table 12, I do not trust the result in 1983 because R 2 is lowest among the coefficients and only one FTA was signed in this period (that is, CER, which is the treaty between Australia and New Zealand). The results in the Difference-in-difference for each period between 1998 and 2001 are consistent with those in the previous panel analysis. But the values in the Difference-in-difference are smaller than in the panel analysis. VIII. Limitations of Analysis VII. Conclusion 21 Reference Blonigen, A., Davies, Ronald B., and K. Head. 2003.

(2005) Leshier and Miroudot (2006) Methodology Explanatory Variables Gravity model, Panel fixed effect Multilateral FTA, GDP, Distance, Common border, Colonial, Common language RTA- Regional Investment Provision / Regional Trade Provision, GDP, Education enrolment, Inflation, Roads, Region Multilateral FTA, GDP, Distance, per Capita GDP, Openness, Common border, Colonial , Common language. Findings The regional integration, on average, contributes to attracting FDI but the benefits are unlikely to be distributed evenly. The type of region matters for attracting FDI. The position of countries within a region matters for attracting FDI. FTA increases FDI by 14-35% from member countries and by 28%-35% form non-member countries. Spatial GM methods Europe agreements between EU and CEE members, GDP, per capita GDP RTA increases FDI up to by 78% among European countries. Gravity model, Tobit regression, OLS, Time varying country fixed effects, Panel fixed effect. Poisson regression RTA, GDP, Distance, Tariff, per capita GDP, Exchange rate, Common Language, Common border, Colonial Investment provisions are positively associated with trade and, to an even greater extent, investment flows 24 Table 2- Variable Definitions Main variables Definition I J T FDI ijt Parent country Host country Year (1982-2004) Outward FDI stocks of i to j at t in US dollars Fijt ln FDI ijt GDPjt (GDPjt ) Current GDP of i (j) at t in 2000 US dollars GDPijt ln( GDPit GDPjt ) ln{1 [GDPit /(GDPit GDPjt )]2 [GDPjt /(GDPit GDPjt )]2 } SIMI ijt PercapitaGDPit Per capita GDP in i (j) in year t in 2000 US dollars ( PercapitaGDPjt ) SK ijt ln( percapitaGDPit ) ln( percapitaGDP. jt ) 5 DISTij ln(Bilateral distance (kilometers) between home country i and host country j) DISTij SK ijt [ln( Dist ij ) [ln( percapitaGDPit ) ln( percapitaGFDPjt )]] GDP [ln( GDPit ) ln( GDPjt )] [ln( percapitaGDPit ) ln( percapitaGFDPjt )] ijt SK ijt FTAijt 1 after the FTA has been signed between country i and j at t, 0 otherwise Fixed country-pair effects it Table 3- Signs of independent variables on horizontal FDI GDP Whole countries + Expected signs Intra-OECD + Extra-OECD + SIMI ijt + + + SK ijt +/− − + DISTij SK ijt +/− + − +/− − + FTAijt +/− − + FTAijt DISTij +/− + − OPEN jt + + + Independent variables ijt GDP ijt 5 SK ijt For the robust test, I used secondary school enrollment share and tertiary school enrollment share for the skill difference.
