Current account dynamics and capital mobility in the newly industrialized countries

This paper examines the current account dynamics in a group of ten newly industrialized countries (NICs) during the period 1980–2012 using a panel error-correction model. The model is also used to empirically test whether the degree of capital mobility is positively related to financial openness. The Chin-Ito (2006, 2008) financial openness index is used to classify the countries into different groups, and we place the countries in one group that are similar to each other in terms of their financial openness. Furthermore, to evaluate the extent of capital mobility over the different period from 1980 to 2012, the total period under study is divided into three sub-periods. The estimation results indicate that there exist long-run equilibrium relationships between domestic saving, investment, and current account in all groups regardless of their degree of financial openness. We find that more openness in terms of the capital account is associated with a higher degree of capital mobility in the case of NICs. The empirical result also indicates that the degree of capital mobility is higher in the first and third sub-period.     

The Feldstein-Horioka puzzle in African countries: A panel cointegration analysis

This paper investigates the Feldstein-Horioka coefficients for 37 African countries using the recently developed Pooled Mean Group (PMG), Fully Modified OLS (FMOLS), and Dynamic OLS (DOLS) panel cointegration techniques. The empirical findings reported in this paper reveal that savings and investment are non-stationary and cointegrated series. The estimated coefficients using FMOLS, DOLS, and PMG are 0.38, 0.58, and 0.36, respectively, for the sample as a whole for the period from 1970 to 2006. These results confirm previous studies' findings that capital was relatively mobile in African countries compared to OECD countries. In addition, our study shows that there are marked differences in savings retention coefficients for different country groups in Africa (CFA franc zone and non-CFA franc zone countries, oil-producing and non-oil-producing countries, civil law and common law countries). These results have some policy implications.     

HAS INTERNATIONAL CAPITAL MOBILITY INCREASED IN ASIA? EVIDENCE FROM THE POST‐1997 FINANCIAL CRISIS PERIOD

This paper examines whether international capital mobility in Asia has increased after the 1997 Asian financial crisis by estimating the Feldstein‐Horioka (FH) coefficients using panel cointegration and dynamic OLS regressions. In the benchmark estimation, we find that the FH coefficients of ten Asian economies decrease significantly from 0.65 during the pre‐crisis period to 0.32 during the post‐crisis period. Furthermore, the coefficient for the post‐crisis period is less statistically significant than that for the pre‐crisis period. The extended model estimations with additional control variables controlling for the business cycle, different foreign exchange rate systems, and capital control also show the results which are consistent with the benchmark estimation results. Rolling regressions show a consistently declining trend of the FH coefficients in Asia during our sample period. These results provide consistent evidence, according to the FH proposition, of increasing international capital mobility in Asia during the post‐1997 Asian financial crisis period.

The Feldstein–Horioka puzzle revisited: Is the home-bias much less?

The large correlation between domestic savings and investment is well documented and is known as the Feldstein–Horioka puzzle. We demonstrate that estimates of the FH coefficients using the standard framework are biased upward in the presence of highly positively correlated inward and outward capital flows. Using data for the 14 OECD countries, the analysis shows that the significant home bias documented by FH and others is also consistent with much higher levels of capital mobility when capital outflows and inflows are highly positively correlated. Taking account for these correlations reduces the estimated home bias somewhere between 45% and 90%.     

资本流动性:基于中国及其他亚洲新兴国家的比较分析

衡量发展中国家资本流动性的方法有总量规模法、储蓄—投资相关法、Edwards模型以及货币自主性检验法等四种方法。本文主要运用前三种方法测度了中国改革开放以来资本的流动性,并用前两种方法比较了中国和其他亚洲新兴国家资本流动性的差异。实证结果表明,所有亚洲新兴国家金融市场处于一种开放状态,并且在所有亚洲新兴国家中,中国的资本流动性是最低的。通过运用Kalman滤波技术对中国的资本流动性进行动态分析,并没有发现1997年亚洲金融危机后中国采取更加严格的资本管制对资本流动性产生影响的证据。实证研究发现,在1997年亚洲金融危机爆发前,中国的资本流动性远低于其他亚洲新兴国家。对于发展中国家资本市场的开放来说,采取渐进式改革而不是激进式改革可能更为明智、更加合理。     

Saving–investment correlations, capital mobility and crowding out: some further results

This study attempts to reassess the evidence on the degree of capital mobility and crowding out by applying a varying coefficients model to data on 19 OECD countries over the 1971–1999 period. Our period-specific results strongly support the crowding-out effect as well as the low capital mobility argument for this group of countries as a whole. However, the strength of the crowding-out effect appears to weaken and the degree of capital mobility to increase in the 1990s as compared to the 1970s and 1980s. We also classify countries into five groups according to the relative size of the government sector. Our group-specific results indicate that the degree of capital mobility is generally lower and the crowding-out effect generally stronger, in country groups with smaller governments. The differences are especially evident when we compare the group with largest government size with all other groups, those differences between the latter being much more modest. However, significant differences in the country-specific results suggest that it is prudent to be cautious when we draw conclusions about crowding-out and capital mobility for specific countries from the period-wise or group-wise results. This is particularly important in drawing policy implications for specific countries.     

The ‘real’ explanation of the Feldstein–Horioka puzzle

This article shows that global capital markets cannot, by themselves, achieve net transfers of financial capital between countries and that both the integration of global financial markets and the integration of global goods markets are needed to achieve net transfers of capital between countries. Frictions (barriers to mobility) in one or both of these markets can impede net transfers of capital between countries, produce the Feldstein and Horioka (1980) results and prevent real interest rates from being equalized across countries. Moreover, there is empirical evidence that barriers to the mobility of goods and services are an important obstacle to international capital mobility.     

Testing for capital mobility: A random coefficients approach

This paper extends the Feldstein-Horioka (1980), Feldstein (1983) and subsequent studies on the degree of capital mobility, by adopting a random coefficients model. This approach is more general in that it permits inter-country variations in the degree of capital mobility to arise due to the differences in size as well as in other institutional or structural characteristics. In addition, it is a refinement of stochastic laws as defined by Pratt and Schlaifer (1984, 1988). Our results point to significant inter-country differences in the degree of capital mobility, thereby lending support to the random coefficients approach. In particular, our results indicate that, on average, the degree of capital mobility is much higher than implied by fixed coefficients approach. Finally, country size itself does not appear to bear a systematic relationship with the degree of capital mobility as suggested by Murphy (1984).We are grateful to two anonymous referees, and Baldev Raj, Editor of the journal for helpful comments and suggestions. The usual caveat applies.     

The Feldstein–Horioka puzzle in groupings of OECD members: A panel approach

This paper investigates the relationship between investment and savings in 26 OECD countries and demonstrates that the relationship changes when the countries under consideration in the selected panel vary. Accordingly, panel estimations using annual data for the period from 1970 to 2008 have been made for various groupings of developed countries, specifically the OECD as a whole, the EU15, NAFTA and the G7. Additionally, the paper examines changes in investment savings relationships when the presence of structural shifts in developed countries – where such exist – are taken into account. Recently developed panel techniques are employed to examine the investment savings relationship and estimate saving-retention coefficients. The empirical findings reveal that the Feldstein–Horioka puzzle exists only in the panel of G7 countries, wherein the saving-retention coefficient is estimated as 0.754 and 0.864 (for the full sample of G7 countries and for stable G7 countries, respectively). The estimated saving-retention coefficient for unstable G7 countries is 0.482, which indicates a higher level of capital mobility in unstable countries with respect to stable ones. This conclusion is further supported by the estimations for OECD countries and the EU15.     

Financial sector development and domestic savings in South Asia

Given the limited capital flows to developing countries in South Asia, domestic savings is the primary source of investment and growth. Financial sector development and access to financial institutions are important determinants of savings ratios in developing countries. In this context, we empirically examine the role of financial development on savings ratios of five South Asian countries after controlling for other relevant variables for the period 1975–2010 and also for two sub-periods—the pre-reforms period (1975–1991) and the post-reforms period (1992–2010). We find that financial sector development positively affects total and private savings in South Asia along with per capita income, share of agriculture and foreign savings. Results also support the humped-shaped relationship between financial development and savings. The causality results support that financial development leads to higher savings mobilisation in South Asia.     

“FH之谜”在省际的应用及其理论解释

用FH方程来解释省际的资本流动状况,通过面板时间序列方法检验发现储蓄率与投资率都是非平稳的,但它们存在协整关系;对FH系数进行估计,得出系数不是很显著,因此认为资本在我国省际具有很高的流动性。这种高流动性是地方政府干预的结果。一方面资本流动对长期经济发展是有利的;另一方面中央政府在晋升考核中对经济绩效非常偏好,使得地方政府倾向于基础设施投资以吸引资本流入。这些因素使得省际有很高的资本流动性。     

A Cross‐country Causal Panorama of Human Development and Sustainability

This paper conducts a multivariate causal analysis for: human development, demographic transition, urbanization, technology, sustainability, democracy/autocracy, good administration, and economic integration. A 15 × 18 causal coefficient matrix is estimated using a cross‐country panel for the 1985–2010 quinquennia. Each matrix entry is estimated using three types of instrumented regressions: (a) levels regressions; (b) growth regressions; (c) growth regressions also containing the contemporary growth of independent variables. The instruments are the 1970–1980 values of the variables. It is found that from 1980 to 2005 income and human development reacted relatively quickly and positively to globalization. However, institutions changed slowly, and the fundamental long‐term causes of divergence, namely demographic transition, urbanization, and technology, were weakly and even negatively affected by integration. The results also suggest human development and sustainability are complementary. Hence technology transfer to the poor and poor regions may provide a sustainable policy tool for development, promoting demographic transition, human development, and convergence.     

Impact of oil booms and busts on human capital investment in the USA

This paper uses Census IPUMS data from 1970 to 2000 and ACS data from 2010 to estimate the impact of oil booms and busts on wages and human capital formation in the USA. The paper finds that the oil boom between 1970 and 1980 was associated with a slower growth in the relative demand for skills in the oil and gas sector and regions where the sector had a large presence. The oil boom led to a sharp rise in real wages and a modest decline in college wage premium in oil-rich regions in the USA. Using a synthetic cohort approach, the paper finds that relative to cohorts who went to high school in the pre-oil boom period, the cohort reaching high school age during the oil boom was about 1–2% points less likely to have a college degree by 2000 and 2010.     

Cognitive skills,innovation and technology diffusion

This article presents new international estimates of human capital for the period 1970–2003. The new latent index is used to re-examine the Benhabib and Spiegel (2005) model of technology diffusion in a horse-race with the competing indicators of Barro and Lee (2010) and Hanushek and Wößmann (2009). Analysis employs cross-section and panel econometrics, extends beyond the Cobb–Douglas technology, and deals with endogeneity bias. Robust evidence confirms the significance of cognitive skills as a driver of innovation and diffusion. Although there is substantial diversity, the new human capital index has declined in many countries in Africa and the OECD.     

Saving–investment Association and Regional Capital Mobility in China: A Nonparametric Panel Approach

Using a nonparametric panel data model, this paper estimates the degree of time‐varying and province‐specific capital mobility in China during 1970–2006. We estimate the savings–investment association, that is, the savings retention rate à la Feldstein and Horioka, as a measure of capital mobility. We also split the total savings (investment) into private and government savings (investment) to explore the role of government in improving capital mobility. Over time, we find an improvement in capital mobility after the mid‐1990s. Across provinces, we observe higher capital mobility in eastern/coastal regions. From the 1990s, the government is found to play a less important role in promoting capital mobility. Across provinces, the government is found to be more important in either the municipalities (Shanghai and Beijing) or the less developed inland provinces.     

The precise form of uncovered interest parity: A heterogeneous panel application in ASEAN-5 countries

A notable feature of the empirical studies on uncovered interest parity (UIP) is that almost all published papers rely on the approximate form of UIP using substantially the same database of developed economies. It can, therefore, not be ruled out that the refusal of UIP condition is simply the outcome of a misspecification of a commonly used model and an elaborate data snooping process. In order to overcome this specification problem, this paper uses the precise form of UIP and examines its empirical validity based on a sample of ASEAN-5 member countries. Using the heterogeneous panel cointegration tests, our empirical results indicate that the gross domestic return and the uncovered gross foreign return are cointegrated in the long run. The long-run cointegrating coefficients are then estimated using the fully modified OLS (FMOLS) and the dynamic OLS (DOLS) proposed by Pedroni. The estimated long-run coefficients suggest that UIP only holds for Singapore. These results indicate that the Singapore financial market is highly integrated with the US market. As for the other four countries, the precise UIP hypothesis is strongly rejected suggesting that the financial markets in these emerging economies have not fully liberalized and, therefore, limited the international financial market integration. By examining international finance market linkages between ASEAN-5 and the US economy, we provide some policy implications that can be used as guiding tools for financing and investment decisions in ASEAN-5.     

A varying-parameter emprical model of balance of payments determination under fixed exchange rates: results for the UK and West Germany

The post-war period and particularly the 1960s witnessed a marked increase in the degree of international capital mobility due to various factors. Empirical studies of international financial flows during the 1960s generally balance model of the external account is developed which structural instability. A portfolio balance model of the external account is developed which allows a varying level of capital mobility and which nests the pure monetary model (perfect capital mobility). The upshot is a varying-parameter empirical specification. This is estimated for the UK and West Germany using Kalman filtering techniques. The model performs well and indicates an upward trend in capital mobility over the period, particularly after 1968.     

The role of international reserves holding in buffering external shocks

An extended literature analyses the accumulation foreign exchange holding observed in many developing and emerging countries since the 2000s. Empirical studies on the self-insurance motive suggest that high-reserves economies are more resilient to financial crises and to international capital inflows volatility. They show also that pre-crisis foreign reserve accumulation explains post-crisis growth. However, some papers suggest that the relationship between international reserves holding and reduced vulnerability is nonlinear, meaning that reserve holding is subject to diminishing returns. This article devotes more attention to the potential nonlinear relationship between the foreign reserves holding and macroeconomic resilience to shocks. For a sample of nine emerging economies, we assess to what extent the accumulation of international reserves allows to mitigate negative impacts of external shocks on the output gap. While a major part of the literature focuses on the global financial crisis, we investigate this question by considering two sub-periods: 1995–2003 and 2004–2013. We implement threshold VAR model in which the structure is allow to change if the threshold variable crosses a certain estimated threshold. We find that the effectiveness of reserve holding to improve the resilience of domestic economies to shocks has increased over time. Hence, the diminishing returns of foreign reserve holding stressed in the previous literature must be qualified.     

Does human capital constrain the impact of foreign direct investment and remittances on economic growth in Ghana?

This article empirically investigates whether human capital constrains the impact of Foreign Direct Investment (FDI) and remittances on economic growth in Ghana. An economic growth model for Ghana is specified and estimated using Fully Modified Ordinary Least Squares (FMOLS) estimator and employing annual data spanning the period 1965 to 2008. Empirical results indicate that FDI and remittances are key determinants of economic growth in Ghana. Results indicate that human capital enhances the impact of FDI and remittances on economic growth. Although both government expenditure and trade openness are growth-enhancing, government expenditure appears to crowd-out private investment. Empirical results also indicate that domestic inflationary pressures, unstable political environment and volatile global economy exert a negative impact on economic growth in Ghana.     

Twin Deficits in the European Countries

Public debt is a burden on future electors and taxpayers. In the absence of constitutional constraints, the incumbent government may show the cost of some public expenditures or tax reductions toward the future by financing them via new debt. However, according to the Ricardian theorem of public debt, the burden of debt is always anticipated via increased saving. If this theorem were true, a budget deficit would not affect the current account of the balance of payment. This paper analyzes the relationship between trade deficit and budget deficit. Using yearly data for the period between 1970 and 2010 in 33 European countries, we find evidence supporting the hypothesis that a chronic and robust budget deficit generates a trade deficit. The dynamic estimates show that a 1 % decrease in the government budget surplus/GDP ratio tends to deteriorate the current account/GDP ratio of 0.37 %, confirming previous studies with a different empirical basis. Dividing the sample period into two sub-periods (1970–1991 and 1992–2010), empirical findings show that current and past values of government budget influence trade balance in the first sub-period, whilst past values of government budget affect trade balance in the most recent years. Moreover, the estimated effect of government budget on current account balance is positive and equal to 0.48 and 0.30, respectively. For the high deficit countries, a long-run relationship between these variables has been found, showing that one percentage point increase in budget surplus/GDP ratio is associated with an improvement in the current account balance of roughly 0.15 percentage point. The estimated long-run government budget elasticity is negative and statistically significant, while the estimated speed of adjustment is equal to 0.33. Finally, Granger causality tests show mixed results.
