Institutional Quality and Economic Growth : The Case of Emerging Economies

The roles of institutional quality on economic growth are still heavily debated in the literature. This paper investigates the impacts of institutional quality on economic growth for 29 emerging economies over the 2002-2015 period by employing System Generalized Method of Moments (SGMM) estimators. We find the significant positive impacts of institutional quality on economic growth. The institutional quality impedes the positive effects of foreign direct investments (FDIs) and trade openness on economic growth. However, institutional quality improvement can mitigate the competition brought by trade openness in the areas FDIs operate to optimize their spill-over effect.


Introduction
An important issue for both academic and pratical studies is the extent to which determinants of economic growth play in different countries [1], meanwhile the economic grow this essential to maintain and improve the international competiveness of a country [2] [3].Although economic growth has been widely researched, the traditional economic theories lack a framework explaining the differences in economic systems between countries beyond human capital, physical capital, labor, technology, and natural resources (e.g., see [4] [5]).Recent research in institutional economics has arisen as an attempt to provide a framework investigating those residual differences ( [6] [7]).High institutional quality has been argued as an economic growth momentum by incentivizing economic activities such as consumption and investment [8] [9], improving effi- 1944 Theoretical Economics Letters ciency [10], allocating resources more efficiently [11] [12], protecting property rights and supporting freedom of choice [13].
The literature also argues the indirect impact of institutional quality on Gross Domestic Product (GDP) via the growth effect of trade openness [14] and the growth effect of Foreign Direct Investment (FDI) [15].Institutional quality has been found to strengthen the economic growth effect of trade openness as better institutional quality tends to accelerate the advantages from trade such as specialization and economies of scale in advanced economies [14].Nevertheless, emerging economies are less comparative and trade advantages may take time to materialize [16].This raises the concern on the impact of institutional quality improvement on the economic growth effect of trade openness in emerging economies.In addition, the literature largely supports that good institutional quality can escalate the economic growth effect of FDI by better facilitating the technology transfer and knowledge spill-over processes [17].However, the literature largely ignores the impact of institutional quality on the economic growth effects of both trade openness and FDI simultaneously.This study is the first attempt examining the role of institutional quality in moderating the impacts of the nexus of trade openness and FDI on economic growth in emerging economies.This is imperative as emerging economies are increasingly opening to trade and foreign investment which may mutually affect economic growth.
This study contributes to the literature on two fronts.First, the study provides new arguments on the impact of institutional quality on the economic growth effect of trade openness in the short run for emerging economies.In contrast to the evidence documented for developed countries, institutional quality improvement tends to impede the economic growth effect of trade openness and FDI in emerging countries in the short run.Second, the study extends the economic growth theories to incorporate the role of institutional quality on the mutual effects of trade and FDI on economic growth in emerging economies.
The study finds that better institutional quality can mitigate the competition brought by trade openness in the areas that FDIs operate to optimize their spillover effect.The remaining of the study is organized as followings.Section two reviews the literature and develops hypotheses.Section three discusses data and methodology.Section four presents the data analysis.Section five concludes the study.

Institutional Quality and Growth Effect of Trade Openness
The impact of trade openness on economic growth has been well studied following endogenous growth model (see [18] [19]).This strand of literature argues that trade openness tends to enhance economic growth by improving domestic productivity and taking advantage of economies of scale which encourages specialization.This is because trade openness stimulates competition which pres-Theoretical Economics Letters sures domestic firms to innovate for higher production efficiency (see [14]).Competition also serves as the channel to eliminate uncompetitive firms, so that resources will be allocated to more competitive firms which further improve economic growth [14].The empirical studies largely support the positive effect of trade openness to economic growth (for example, [20]).The literature also argues the important role of institutional quality on the growth effect of trade openness (see [14] for the review).The literature points out that better institutional quality could accelerate the growth effect of trade openness by better facilitating efficiency improvement process and strengthening the advantages of economies of scale [14] [16].Our study argues that, in the short run, better institutional quality may impede the growth effect of trade openness.We argue that better institutional quality reduces uncertainties related to international trade activities such as imperfect contract enforcement [21], and protection of intellectual property rights [22], competition brought by foreign firms becomes fiercer.While it takes time for domestic firms to promote efficiency, fierce competition may force domestic firms to reduce their production as the market is shared to foreign counterparts.If the domestic market share shrink is not compensated by exporting expansion, better institutional quality reduces the growth effect of trade openness.In addition, it has been documented that emerging economies are not as efficient as advanced economies [23], hence, better institutional quality may facilitate import more than export for emerging economies, leading to slower economic growth in the short run.For this reason, we hypothesize that the interaction of institutional quality and trade openness has a negative impact on economic growth in emerging economies (Hypothesis 1).

Institutional Quality and Growth Effect of FDI
Endogenous growth theory posits that the FDI spillover effect (i.e.technology transfer and knowledge spillover) can be transformed into productivity improvement and consequently economic growth [24] [25].In addition, FDI also complements to domestic investment by relaxing the liquidity constraint, therefore, escalating economic growth [26].[17] reviews the empirical studies on the impact of FDI on economic growth and points out that the mixed evidence is conditional on the institutional quality.[17] argues that poor institutional quality is associated with high transaction costs, increased risk for long term commitment, loosening the linkages between foreign affiliates and domestic firms, and hence, limits the spillover effect.In addition, better institutional quality is also argued to mitigate the crowding out effect of FDI by encouraging foreign investment into pioneering industries and lessening competition with domestic firms, so that the growth effect of FDI will be further strengthened.In line with this argument, we posit that the positive effect of FDI on economic growth will be stronger in countries with relatively high institutional quality.We further examine the impact of the nexus of institutional quality, FDI and trade openness on economic growth.

Methodologies and Data
The study investigates both the direct effects of institutional quality on economic growth and the indirect effects of institutional quality on economic growth through the interactions with the international trade and capital flows in emerging markets.Following [27], the impact of institutional quality is estimated in the model as below:

Results and Discussions
The model is estimated with SGMM estimator to control for potential endonegeity ( [32] [33]).This estimator is also argued to be efficient for unbalanced data with relatively small time period and large cross-section groups (countries) Table 2 and Table 3 present the baseline results without institutions for GDP per capita growth and GDP growth, respectively.The error terms are free of unit root and serial correlation.Population growth is included in GDP growth regression only.Capital growth, technology, population growth, FDI and trade openness significantly improve economic growth.The positive impact of human capital is only statistically significant in GDP per capita growth, but not in GDP growth.Economic growth tends to slow down at higher GDP per capita levels.
This confirms the converging trend in economic growth among emerging markets, and this is consistent with the converging theory in economic growth field [34] [35].
The impacts of institutional quality on GDP per capita and GDP growth are presented in Table 4 and Table 5, where the role of each institutional quality component is examined alternatively.The results in Table 4 show that control of corruption, government effectiveness, rule of law, and voice and accountability significant improve GDP per capita growth.These results are in line with theories and previous studies on the effects of institutional quality on economic growth [36] [37].Although political stability and regulatory quality have expected positive impacts on GDP per capita growth, they are not statistically significant.All six elements of institutional quality do not show any significant impacts on GDP growth in Table 5.The increasing trade openness of emerging markets invites competition from foreign firms especially from developed countries, and institutional quality improvement will further strengthen the competition, leading to economic slowdown in the short run.This result is in line with findings from African countries Theoretical Economics Letters [38] but contradicts the findings from developed economies [14].This can be explained by the fact that the competitive capability of emerging markets are low so that foreign firms have more advantages in competing with the domestic firms when the institutional quality is improved thus the economic growth is lower.
The coefficient of the interaction between institutions and FDI is negative.This does not support hypothesis 2 and contradicts the findings of [17] that better institutional quality can promote the growth effect of FDI.Our results show that the growth effect of FDI is stronger in countries with lower institutional quality.This controversial result can be explained that FDI may provide greater incentive for institutions improvement in countries with low institutional quality, which in turn positively supports economic growth.
Interestingly, we find that the interaction between FDI and Trade has a negative impact on economic growth.We posit that trade openness brings fierce international competition to emerging markets [14], faces domestic firms to unfavorable environment, and hence, impedes the FDI spillover effect in the short run.However, the negative effect of trade in association with FDI is lessened in the countries with high institutional quality.This is reflected in the significant positive coefficient of the nexus of institutional quality, trade openness and FDI.This novel result indicates that institutional quality improvement can mitigate the competition brought by trade openness in the areas that FDIs operate to optimize their spillover effect.

Conclusion
Institutional quality has an important role in stimulating economic activities and accelerating economic growth especially in emerging markets where great efforts have been put to improve institutional quality.In this paper, we collect data in the period of 2002-2015 for 29 emerging markets to examine the impacts of institutional quality on economic growth.By conducting the system-GMM estimators, we find that the institutional quality has positive impacts on economic growth in emerging markets.In addition, institutional quality improvement has negative impacts on the economic growth effect of trade openness and FDI.The findings also demonstrate that the competition brought by trade openness may impede the spill-over effect of FDI.However, better institutional can mitigate the competition brought by trade openness in the areas that FDIs operate to optimize their spill-over effect.Policy makers in emerging economies should improve institutional quality and competitive capacity of domestic firms before promoting trade openness and FDI.This also provides implication to trade policies for the period 2015-2018 that emerging economies should focus on improving their capability in absorbing the benefits from economic integration with stronger institutional reforms.
