Abstract
The pattern of capital inflows in developed and developing economies are different because of dissimilar economic and political structures. From the point of view of host country, especially the developing countries, portfolio flows are considered to play a pivotal role in bridging the saving investment gap and providing foreign exchange to finance current account deficit. While the investors of developed country invest in portfolios of different countries to diversify the risk and earn more returns, foreign portfolio investors generally go for short-term investment to reap the benefits of good economic conditions and they tend to withdraw their investments during the period of recession. This article identifies the determinants of foreign portfolio investment (FPI) in developed and developing economies. Though the movement of capital among different countries is researched in depth by existing literature, the present study adds to literature by identifying the institutional factor involving freedom index. The institutional factors aid in identifying the determinants of FPI among select developed and developing countries. This study seeks to answer, where the funds of foreign portfolio investors are headed. And also the reasons of attractiveness for FPI among different sets of countries. The sample of the study is limited to a set of 19 developed and developing counties for the period of 10 years (2004–2013). We study the determinants of FPI for a group of developed and developing countries using fixed and random effects. Additionally, we use panel generalized method of moments (GMM) suggested by Arellano and Bond (1991, The Review of Economic Studies, 58(2), 277–297). This methodology is suitable to remove the problem of endogeneity which static model is not able to capture. The results of model also incorporates persistence effect considering lagged value of dependent variable. The study empirically tests the various factors that determine the inflows of FPI and analyses their performance during different stages of the economic cycle in the last 10 years. Implicitly, in case of developed countries, it was observed that interest rate differential, trade openness, host country stock market performance and US stock market returns are significant trendsetter, while in developing countries, freedom index, interest rate differential, host country stock market performance, trade openness, US stock market returns and crisis period (2006–2008) significantly influence the inflow of FPIs. Dynamic model supports that as a group of 19 countries, portfolio investments are significantly influenced by interest rate differentials, freedom index, US stock market and host country stock market returns.
Introduction
The growing removal of restrictions on trading of international financial assets has led to surge in the flow of capital across the world. The two forces, globalization and liberalization are the roots of extraordinary foreign capital inflows and have become the engines of economic development. The process of globalization increases competitiveness in environment, leading to higher efficiency in the system. Implicitly, all economies are initiating major reforms so as to make their countries more vibrant and strategically competitive. The economies are making conscious efforts to attract foreign financial capital to achieve the objective of higher economic development. Most developing countries are achieving the twin goals of macroeconomic stabilization and structural adjustments to reduce the country’s borrowing fiscal imbalances. The main focus of these policies are formulated to balance external debt and trade deficits coupled by the process of fiscal, monetary and industrial reforms being set with great zeal. Globalization leads to integration of home economy with the world by forming global financial relationship. The dimensions of financial globalization include abolishing credit controls, deregulation of interest rates and finally allowing foreign direct investment (FDI) and foreign institutional investment (FII) in multiple sectors of economy in the form of capital flows. Foreign capital inflows have significant role in the developmental process of all countries. Developed countries require foreign capital inflows for sustainable development, substantially developing countries need it for higher economic growth and augmenting domestic investment critical for improving the quality of life of majority of people. It is a channel through which developed as well as developing countries have access to foreign capital, which basically comes in two forms: (a) FDI and (b) foreign portfolio investment (FPI). FDI and FPI are similar as they both originate from foreign investors, but fundamental difference exists which is the degree of control. FDI investors exercise controlling position in domestic firms and actively getting involved in management, while FPI investors are passive investors not actively involved in day-to-day operations and strategic plans of domestic companies. Foreign investment has emerged as the engine of economic growth in a globalized world and is considered as one of the important areas in the study of international business. Research in this area has been found to be very extensive, but few deficiencies are observed in literature. First, the most of the research on foreign investment are focused on FDI, whereas the topic of foreign indirect investment or foreign portfolio investment (FPI) has received less attention (Li & Filer, 2007). Second limitation highlights that the effect of governance environment has been left out while considering the determinants of FPI. Later on, Wu, Li and Selover (2012) has taken into account government environment to determine the inflow of foreign portfolio investment. The prior literature suggests that economic development level, financial markets, geographical or cultural factors are important for foreign capital inflow. On the one hand, these are certainly the factors that determine the inflow of foreign capital, and on the other hand, literature is silent about institutional factors and freedom index. How does freedom index play a role? If it really plays a role, how and why does it play a role? In this study, we try to fill the gap taking into consideration freedom index (as a measure of institutional factors) of the countries as one of the important determinant in performance of foreign capital inflows.
The study deals with foreign portfolio investment which refers to investment made by residents of a country in financial assets and production process of another country, including FII, American depository receipts (ADR) and global depository receipts (GDR). The effects of foreign investment varies from country to country. It can affect the balance of payment, productivity, financial markets and stock market performance. Foreign portfolio investment is a short-term investment, mostly invested in financial markets of the host countries. Here in this article, we focus on two questions: first is that how relevant macroeconomic variables (including institutional/freedom index) are in affecting FPI inflows and second one is that how important common and global shocks have been for the inflow of foreign capital.
Global Trends in FPI (Foreign Portfolio Investment) Inflows
The decade (1998–2008) immediately preceding the global financial crisis observed an exponential surge in worldwide capital inflows and outflows, especially in emerging markets. The favourable trend towards emerging market is because of encouraging demographic characteristics, potential growth and scope of diversification and economic policies, which lead to inflow of high foreign portfolio investment in BRICS countries (Garg & Dua, 2014; Ghosh & Herwadkar, 2009; Srinivasan & Kalaivani, 2015). Global quarterly foreign portfolio index 1 highlights the trend and performance of foreign portfolio investment. Due to global slowdown in 2008, trends of foreign capital inflows drastically decreased all over the world, but capital tend to increase in later years after recovery in the global slowdown due to Asian Financial Crisis. Despite the global slowdown both types of foreign capital inflows (FDI and FPI) showed deterioration trends. Foreign portfolio investment (FPI) declined during the third quarter of 2008 because of global financial crisis, and again due to double-dip recession during the second quarter of 2011, it comes to its inferior level.
Theoretical Background
Foreign investment includes two categories: direct investment and portfolio investment. In direct investment, investors invest in a firm with an intention to have the right to participate in the management of the firm, whereas in case of portfolio investment, investors purchase the securities of firm to earn short-term returns foregoing the interest of ownership. The present study is considering the determinants of FPI and theoretical base for the same is listed:
Portfolio balanced framework: Under this model, foreign investors exploit all the possibilities of arbitrage process present in home and host countries. The empirical model of the present study is motivated by factors suggested in theoretical model of balanced framework. This framework analyses the effects of domestic and global factors on capital flows. Balanced portfolio framework studied pull and push factors that attract foreign portfolio investments. The pull factor represents the domestic country-specific investment risk and returns which attracts foreign investment, and push factors represents global liquidity and other factors that push investments to emerging economies (Mody, Taylor, & Kim, 2001). International finance theory: According to this theory, FPI are foreseeable outcome of investors, those who wish to invest across the countries. Investment in different portfolio leads to diversification of risk and higher returns can be achieved. There are several studies made which documented
the benefits of diversification on portfolio, international funds which bridges the gap of saving and investment across the countries, and reviewed the benefits of capital flows from host country perspective (Dell’Ariccia et al., 2008; Obstfeld, 2009). Capital allocation theory: To follow diversification, foreign investors can invest in either emerging markets or in financial markets of industrialized countries. As per Buckberg (1996), foreign investors monitor two-step process in determining the capital allotment. In the first step, they identify the amount of investment to be allocated; then in the next phase, they allocate the capital in each emerging market on the basis of earnings. This simply indicates that emerging market with high inflow of capital points out the high potential of a country in terms of investment. In other words, this theoretical model proposed to take the industrial and economic growth of a set of emerging markets to identify the potential among them. This simply directs to incorporate stock market returns to catch FIIs. In this way, emerging stock market returns are also included in the proposed empirical model.
In an attempt to fill the gaps in literature, the article is organized as follows: The previous section covered an overview of global trends of foreign portfolio investment and theoretical framework. The next section presents the literature review on determinants of foreign portfolio investment in developed and developing countries. The third section describes research design, including time period, data sources and the econometric methodology employed. The fourth section presents the empirical results and findings of the study. The fifth section concludes the article and the final section covers managerial and policy implications.
Literature Review
Foreign capital inflows have been studied extensively and its importance is widely established in empirical literature. Theories suggest determinants of potential capital inflows are likely to fall in three categories: country-level, industry-level and firm-level determinants. We focus on country-level determinants, including economic and political factors that measure the trends of capital inflows. A snapshot of literature review is given in Figure 1.

Inflow of FPI has been gaining importance as it increases the financial strength of the host country. Contrary to that, capital flight may cause vulnerability in host country. To increase the financial strength of the country, continuous inflow of FPI is required, which is supported by various lightening factors. Researchers stressed on pull and push factors that affect the trends of portfolio investments. Many studies enlist global factors such as interest rates, growth of industrialized countries and many more that have pushed inflow of FPI to developing countries (Byrne & Fiess, 2011; Calvo, Leiderman, & Reinhart, 1993, 1996; Felices & Orskaug, 2008; Kim, 2000; Mody et al., 2001; World Bank Report, 1997). Another set of studies consider domestic as well as external factor influencing FPI in developed and developing countries (Chuhan, Claessens, & Mamingi, 1998; De Vita & Kyaw, 2007).
Many studies support foreign capital inflows and their benefits to economy through the process of diversification (Dell’Ariccia et al., 2008; Grubel, 1968; Harvey, 1991; Obstfeld, 2009). The constant removal of restrictions on trading of international financial assets has led to surge of capital across the world during last two decades, and the investment is geared fast towards the developing countries, including BRICS, ASEAN and developing Asia (Garg & Dua, 2014). Developing countries, especially BRICS, attracted considerable amount of foreign capital in terms of direct and portfolio investment wherein China is the highest recipient. Holtbrügge and Kreppel (2012), Morck, Yeung and Zhao (2008) and Mostafa and Mahmood (2015) studied BRICS and G7 countries in terms of development, productivity, markets, consumptions, saving, investments, human capital, innovations, potential and challenges, and predicted that BRICS has the prospects to challenge G7 countries in the coming decades in terms of inflows of foreign capital. The detailed chronological analysis of literature is presented in Table 1.
Research Design
Objective
The objective is to investigate the influence of institutional context of a country in determining the FPI inflows. There is a long tradition of research in international business based on determinants of FPI inflows. The literature has identified multiple factors ranging from macroeconomic to political variables. We propose to identify various economic, political and institutional factors ranging from host country stock market returns to US stock market returns, interest rate differentials to credit worthiness of the country, institutional variables to exchange rates, affecting FPI inflows.
Rationale of the Study
This article makes an important contribution to the existing literature by adding an empirical analysis based on determinants in select developed and developing countries using static and dynamic panel data approach. Most of the studies earlier done in the area of foreign portfolio investment are based on time series data, specific to a country, but the present study tried to incorporate 19 countries in the form of panel data. The study will consider many macroeconomic variables, including pull and push factors such as interest rate differential, freedom index, stock market performance of host country along with US stock market returns with special consideration to crisis period that determine the performance of portfolio investment in host countries among developed and developing countries. Without doubt, many researches have analysed this propaganda, but there are little documented evidences of the existing literature on factors influencing FPI in developed and developing countries. Therefore, the proposed article aims to identify the factors that affects the inflow of FPI in developed and developing countries.
Sample Countries and Period of Data
To analyse the determinants of FPI, 19 countries, including 11 developed and 8 developing countries (enlisted as top 22 recipients of foreign capital inflows prescribed by World Bank report 2012 and 2013), have been selected and presented in Table 2.
Chronological Analysis of Literature Review on Determinants of FPI
This study is limited to 19 countries having data period of 10 years from year 2004–2013, which has been collected form Bloomberg database. Bloomberg is world-renounced database in accuracy and availability of variables used in study, except for freedom index which is extracted from heritage foundations. 2 Variables have been identified as per extensive literature review tabulated in Table 3.
List of Sample Developed and Developing Countries
Choice of Variables
The selected variables enlisted in Table 3 have been captured as per major research studies undertaken across the globe.
Research Methodology
As per the literature review, it was found that OLS, Granger causality, VAR, ARDL, multiple regression, panel OLS, fixed effects and random effects are the methods which have been extensively used in earlier studies. In this study, we have used two research methods, one is static and other is dynamic panel data modelling.
Considering static panel data modelling, the first method employed was pooled OLS estimation. Breusch–Pegan multiplier test rejects the null hypothesis of using pooled OLS estimation over random effects. The next step is to check the applicability of fixed effect or random effect in static model approach. Fixed effect panel are likely to be superior on theoretical grounds, as they control for time variant heterogeneity across the countries and provide relatively robust results. Hausman (1978) test indicates the choice between fixed and random effect specifications.
In general, the models for determinants of FPIs can be studied using following specifications:
where, X, Y and Z are the different vectors of pull and push determinants. This equation represents the static nature of model. The article adopts several approaches to model the determinants of FPI flows.
Description of Sample Variables
Based on theoretical framework and literature review, variables have been identified. We enlist four models with combinations of different pull and push factors. As specified by portfolio balanced framework, the study tried to determine the significance of variables such as credit worthiness of host country, stock markets return of host country, interest rate differentials and many others.
The estimated coefficients and their corresponding significant results for static models are shown in Table 4.
Another methodology applied here is dynamic panel data modelling. Majumder and Nag (2014) specified that total capital inflows are more voluminous, more volatile and more persistent than net inflows. FPIs being the part of foreign capital inflows are also considered to be volatile and is affected by its own lagged values (measuring the presence of persistence effect). Therefore, the use of lagged independent variable adds dynamic nature to analysis. Now the model can be prescribed as follows, considering lagged value of dependent variable.
FPI denotes foreign portfolio investment of country i and time t with i = 1…..N, and t = i…T. c is the constant term,
In static panel data modelling, estimation is done using fixed and random effects. Using lagged dependent variable yield, the model dynamic in nature and least square estimation in this case provide bias and inconsistent results (Baltagi, 2008). To overcome this situation, Arellano and Bond (1991) suggested the usage of instrumental variables by including lag of dependent and independent variables. The inclusion of dependent lagged variable as regressor in Equations (2) and (3) makes the model dynamic and the problem of endogeneity arises. To account endogeneity problem, following García-Herrero, Gavilá and Santabárbara (2009) and Athanasoglou, Brissimis and Delis (2008), we use differenced generalized method of moments (GMM) proposed by Arellano and Bond (1991).
Results Static Model of Developed Countries
Analysis and Findings
Tables 7A and 7B in the Appendices depict descriptive statistics of developed and developing counties. FPI as percentage GDP is quite higher in developing countries than developed countries. In terms of creditworthiness, developed nations are capable to pay off their debts. This is a positive sign for short-run investors, if host country have sufficient reserves in their hand. Developed countries are ahead in interest rate differentials, trade openness and GDP growth, which simply means developing countries are capable enough to mould their macroeconomic policies in favourable to foreign institutional investors.
Tables 8A and 8B in the Appendices showcase the correlation matrix for all listed variables in developed as well as developing countries. Implicitly, the absence of high correlation is observed among the variables. To run regression on data, it must be ensured that data sets should be free from the problems of multicollinearity, hetroscedasticity, autocorrelation and stationarity. By applying few specification tests, we found the eligibility of data sets to run regression-based static and dynamic approach.
To select fixed and random effect approach, we estimate Equation (1) with proposed models as explained earlier and perform Hausman specification test. The null hypothesis of the test signifies the applicability of random effects. Results of each model with Hausman test are marked in Tables 4 and 5 for developed and developing countries, respectively.
In case of developed countries, all models failed to accept the applicability of fixed effect as Hausman test confirms the applicability of random effect model. As per the specifications of the aforesaid econometric models, all four models accept the significant effects of domestic stock market performance and trade on foreign portfolio in investment with addition to interest rate differentials in Models 1 and 2, respectively. Models 3 and 4 demonstrate the significant effect of US stock market performance on capital inflows summarized in Table 4.
In developing countries, all models are having the specifications of fixed effects. The estimation of the model starts with Hausman test, which examine the hypothesis that random effect model is applicable to panel data analysis. Here freedom index, interest rate differential, trade, domestic stock market returns affects the inflows of foreign portfolio investments. Entrant of crisis dummy in Model 4, negatively but significantly affects the foreign portfolio investment. As explained, earlier portfolio investments are like flight investments which comes when economy is in upswing and flies away in case of turmoil. Due to global financial crisis in the year 2008, there is intense decline in inflows of FPI in developing countries. Normally investors lose the confidence of investing in the countries where they had invested previously at a very high rate. After global financial crisis, when economy stabilizes, the portfolio investors regained the confidence in investing in these countries, looking at the potential recovery and institutional factors. The results of static models are outlined in Table 4 for developed countries and Table 5 for developing countries.
Results of Static Model of Developing Countries
This motivates the foreign portfolio investors to participate in such countries where stock market returns are quite high. These results of stock market returns on inflows of foreign portfolio investors are consistence with the findings of Bohn and Tesar (1996), Clark and Berko (1996), Brennan and Cao (1997), Kim and Wei (2000) and Richards (2005). The other variable is trade openness which clearly indicates the openness of economy with the whole world. This is again positive and significant, indicating that trade openness increases the confidence of foreign portfolio investors towards the open policies of the country.
As mentioned earlier, least square estimation leads to inconsistent and bias results taking lagged values of dependent variable as regressor. Therefore, we use GMM to account the problem of endogeneity, heteroskedasticity and consistency. Sargan and Wald test statistics are the test for over-identifying restrictions in the model and goodness of fit, respectively.
Lagged dependent variable of FPI comes out to be highly significant, which confirms the dynamic specifications for the model and justified the usage of GMM methodology. The coefficient of lagged dependent variable as regressor is 0.292, which specifies the moderate degree of persistence of FPI flows, and positive value signifies that countries are able to retain foreign portfolio investment from one year to another. Freedom index, trade openness, GDP growth, interest rate differential, home country stock market and crisis dummy are found to be significant determinants of foreign portfolio investment. GDP growth rate is found to be negatively significant, which supports the argument of arbitrage process. However, the first lag is positively significant to FPI inflows, which specifies the attractiveness to foreign investors to grab higher profits in light of good economic conditions. Considering post estimation tests namely AR (1) and AR(2), coefficients are found to be insignificant which implies the absence of first and second order autocorrelation in data. This does not yield to inconsistency in results. Inconsistency will imply, if second order autocorrelation is present (Arellano & Bond, 1991). Wald test statistics gives chi-square value as 2,254.10 at 15 degree of freedom, rejecting the null hypothesis that estimated coefficient are jointly significantly different from zero, meaning that model is having predictive power (see Table 6).

Conclusion
The study is related to a panel of 19 countries, 11 developed countries and 8 developing countries, and adopted several approaches to model FII inflows. The first method employed is the pooled OLS estimation, then fixed effect model. And the result of Hausman (1978) tests indicates the applicability of fixed effect or random effect model. Finally, we use GMM suggested by Arellano and Bond (1991) to overcome the issues of endogeneity and unobserved heterogeneity.
The findings of the study are based on Gourinchas and Jeanne (2006) and Herrmann and Kleinert (2014). The last decade had experienced the collapse and surge in global FPI, and this study tried to analyse the driving force towards the vulnerabilities of portfolio investment. The study focuses on the debate whether it is the push or pull factor that determines capital inflows. It is found that both pull and push factors determine the inflow of foreign capital in developed and developing countries. The author observed that foreign portfolio investors have watch on interest rate differentials, policy framework of a country reflected in trade openness, performance of home country stock market and US stock market returns as these variables played significant role. In case of developing countries, it is found that freedom index, trade openness, interest rate differential, stock market performance and US stock market performance had a significant impact over foreign portfolio investment, explicitly in developed countries, interest rate differential, host country stock market performance and US stock market significantly played important role in determining the trends of foreign portfolio investment using static modelling. In the final step of analysis, the study tried to capture the economic relevance of dynamic panel specifications with different determinants associated with pull and push factors in explaining foreign capital inflows considering lagged value. And the conclusion is drawn that foreign portfolio investors are quite volatile as they look for short-term gains, and they are persistent in their investment. Majumder and Nag (2015) highlight the presence of persistence in capital flows. And persistence of capital flows measures the degree of predictability. The results of GMM are consistent with the results of static modelling in terms of determining factors that influence inflow of portfolio investment in host country.
This study is considering very important aspect related to growth and development of economies because capital flows are expected to augment growth of developing countries. Once capital flow moves from rich economies (economies with lower interest rates due to capital abundance) to poor economies (economies with higher interest rates due to capital scarcity), it will escalate the path of economic development in emerging and developing countries. Tong and Wei (2009) suggested that emerging and developing economies should reap out the benefits of foreign capital inflows, when the foreign capital is steady, less volatile in nature and will not disrupt the financial stability of the economy. The present study adds the importance of institutional factors considered in freedom index, along with other variables as important determinants FPI. Freedom index, exchange rate, home country stock market, interest rate differential, US stock market returns, crisis period and many more are analysed and found significant in attracting foreign capital, which in turn need to be captured diligently for policy framework and stabilizing the economy. FPI inflows are having moderate persistency which means its past behaviour affects the current inflows. Policies in past affects the current inflows, and it continues until foreign investors can reap out the benefit out of it. The growing importance of foreign capital flows in emerging and developing countries leads the involvement of government in providing a common platform to raise information flows and better coordination in negotiations and executions of projects (Rasiah, Gammeltoft, & Jiang, 2010).
Managerial and Policy Implications
The pattern of capital inflows in developed and developing economies are different because of dissimilar economic and political structures. From the point of view of host country, especially the developing countries, portfolio flows considered to play pivotal role in bridging the saving investment gap and provide foreign exchange to finance current account deficit. The investors finance in portfolios of different countries to diversify the risk and earn more returns. The market participants may consider this study to predict the future movement of FPI in a country/company based on volatility of stock market returns, exchange rate, interest rate differential, economic environment, trade openness and GDP growth. Various multinational companies are interested in forecasting and managing their portfolios to increase their wealth. They consider that the movement of FPI inflows are predicted by its natural determinants. In other words, portfolio managers are also able to identify the spillover effects of FPIs on various determinants. Hence, they can make out the policies considering attractiveness of firms for FPI by adopting good governance. Regarding the policy framework, policies should be addressed in such a way to attract more capital for long-term perspective rather than for short term. No doubt, foreign capital inflows provide financial stability in host country, so stability in capital inflows should be maintained by attracting more of capital inflows by providing them long-term benefits. Many developing countries such as China and India are having superior track record in attracting FPI inflows. Business friendly environment, strategic policy initiatives for providing economic freedom, and flexible laws can be identified as major forces to attract FPI. Policymakers need to ensure economic & political stability, good law and order mechanism, good governance and also suitable fiscal and monetary policies for higher order capital movement among different countries to attain the objective of economic development.
Limitations
There are inherent limitations in data used in this research. Despite the popularity of economic freedom index and other indices published by Heritage Foundation, these have attracted considerable criticism as well. Scott (1997) argued that this database has missed out some important aspects of regulation. The publisher of the database has adopted causal relationship between economic freedom and economic growth rather than the index itself. However, by using foreign capital inflows, this criticism has been addressed. The study is limited to the period of 10 years. The study is also covering the limitations of statistical tools used and economic environment indicators.
Scope of Further Research
The greater validity of results can be attained using economic freedom with location-specific advantage that a country possesses is likely to influence FPI inflows. However, it is important to replicate the study for additional period of time and additional countries to test whether the relationships uncovered by the present study hold true across the different economic cycles and may provide more viable results. The article has not considered governance index and tax regimes of the countries. These variables can be further studied as the future scope of research.
