Does Economic Policy Uncertainty Predict Exchange Rate Returns and Volatility? Evidence from a Nonparametric Causality-in-Quantiles Test

Recent studies have analysed the ability of measures of uncertainty to predict movements in macroeconomic and financial variables. The objective of this paper is to employ the recently proposed nonparametric causality-in-quantiles test to analyse the predictability of returns and volatility of sixteen U.S. dollar-based exchange rates (for both developed and developing countries) over the monthly period of 1999:01–2012:03, based on information provided by a news-based measure of relative uncertainty, i.e., the differential between domestic and U.S. uncertainties. The causality-in-quantile approach allows us to test for not only causality-in-mean (1st moment), but also causality that may exist in the tails of the joint distribution of the variables. In addition, we are also able to investigate causality-in-variance (volatility spillovers) when causality in the conditional-mean may not exist, yet higher order interdependencies might emerge. We motivate our analysis by employing tests for nonlinearity. These tests detect nonlinearity, as well as the existence of structural breaks in the exchange rate returns, and in its relationship with the EPU differential, implying that the Granger causality tests based on a linear framework is likely to suffer from misspecification. The results of our nonparametric causality-in-quantiles test indicate that for seven exchange rates EPU differentials have a causal impact on the variance of exchange rate returns but not on the returns themselves at all parts of the conditional distribution. We also find that EPU differentials have predictive ability for both exchange rate returns as well as the return variance over the entire conditional distribution for four exchange rates.     

Capital flows and real exchange rates in emerging Asian countries

This paper examines the impact of capital flows on real exchange rates in emerging Asian countries during 2000–2009 using a dynamic panel-data model. The estimation results show that the composition of capital flow matters in determining the impact of the flows on real exchange rates. Other forms of capital flow, especially portfolio investment, bring in a faster speed of real exchange rate appreciation than foreign direct investment (FDI). However, the magnitude of appreciation among capital flows is close to each other. The increasing importance of merger and acquisition (M&A) activities in FDI in the region makes these flows behave closer to other forms of capital flow. The estimation results also show that during the estimation period, capital outflows bring about a greater degree of exchange rate adjustment than capital inflows. This evidence is found for all types of capital flow. All in all, the results indicate that the swift rebound of capital inflows into the region could result in excessive appreciation of (real) currencies, especially when capital inflows are in the form of portfolio investment.     

Explaining Heterogeneity in the Effect of the Exchange Rate and Exchange Rate Volatility on Foreign Direct Investment: A Meta‐Analysis Approach

This study examines the effect of exchange rate and exchange rate volatility on foreign direct investment (FDI) by using a meta‐analysis. We filter out publication bias within the 1,329 estimates, pooled from 101 studies and employ Bayesian Model Averaging to reduce model uncertainty and explain the existing heterogeneity. The results reveal that the exchange rate system, estimation characteristics, and the modeling approach have an important and noticeable influence on the statistical significance and direction of the estimates. On one hand, the impact of exchange rate volatility is relatively lower in countries with higher trade openness, human capital and better protection of intellectual property rights. On the other hand, greater geographical distance and technology gap between the host and the home economy are associated with greater uncertainty and thus accentuate the negative causality between exchange rate volatility and FDI. Such sensitivities suggest that greater emphasis should be placed on reporting estimates of the impact of the exchange rate and its volatility on FDI across a variety of methodological characteristics and specification and estimation choices.     

China's economic development: does exchange rate and FDI nexus matter?

This study aims to investigate the relationship between China's exchange rate, foreign direct investment (FDI) inflows, and economic development. We applied the bound testing approach on aggregate level data from 1981 to 2013. The results showed that the Chinese economy benefitted from a lower exchange rate over this period, and that there was a direct link between FDI inflows and economic development on an aggregate level both in the long and short run. The results of the Granger causality test identified a long‐ and short‐run association among these variables. The GMM estimations with dummies for financial crises and RMB exchange rate policy fluctuations also confirmed the growth enhancing impact of the exchange rate and FDI inflows. To promote sustainable economic development in the future, China should focus on improving the levels of domestic investment and human capital, as well as supervising the level of openness and capital controls.     

The effect of North Korean threats on financial markets in South Korea and Japan

This paper examines the effects of North Korean threats, as measured by the proprietary North Korean Threat Index (NKTI), on financial markets in South Korea and Japan. We examine the effects of the threats on stock markets, foreign exchange markets, and overnight interest rates. We consider causality in mean and variance tests to determine any link between the NKTI and financial variables. The causality-in-mean test results indicate the presence of a causal link running from North Korean threats to stock returns and exchange rate returns in both countries, but no significant link to the overnight interest rate in either country. The causality-in-variance test results indicate no significant impact emanating from North Korean threats. Integrating the North Korean economy into the global economy stands to eliminate these threats and thus to contribute to regional financial stability.     

Does inflation lower productivity? Time series evidence on the impact of inflation on labor productivity in 12 OECD nations

According to proponents of zero-inflation policies, even low rates of inflation create distortions in capital allocation and in price signals, which result in lower rates of productivity growth. This paper tests the hypothesis that inflation has a causal impact (in the Granger sense) on labor productivity growth in manufacturing for 12 countries of the Organization for Economic Cooperation and Development (OECD). In bivariate tests of inflation and productivity and in multivariate tests using controls for cyclical effects, there is no evidence of a consistent relationship between inflation and productivity growth with regard to either sign or magnitude. Therefore, the present analysis does not support the view that further reductions in inflation from already low single-digit levels would have a positive impact on labor productivity growth for major industrial countries.     

Inflation and inflation uncertainty in the ASEAN-5 economies

This study explores the linkage between inflation and inflation uncertainty in the ASEAN-5 countries over the period 1970:01–2007:12. Inflation uncertainty is estimated as a conditional variance in an AR(p)-EGARCH(1,1) model. Granger causality tests show that rising inflation increases inflation uncertainty and that rising inflation uncertainty increases inflation in all five countries. The ASEAN-5 have had low inflation rates relative to other emerging markets. Thus, our study shows that even in low inflation emerging markets inflation can lead to inflation uncertainty and uncertainty can lead to inflation. Given current inflationary pressures in these countries, our results warn of possible costs of not keeping inflation in check.     

Financial market integration, stock markets and exchange rate dynamics in Eastern Europe

International capital flows in a system of flexible exchange rates will affect stock market dynamics and stock market developments should affect capital flows and the exchange rate respectively. In this analysis, four accession countries have been considered in order to examine any potential links between nominal stock market index and nominal exchange rate. For this purpose, monthly data were used. The cointegration concept was employed for testing long-term links and the VAR approach for short-term links. Finally, Granger causality tests were employed for the determination of the exogenous and endogenous variables. The results show that significant links exist between the stock market index and the foreign exchange rate for three countries, where for Poland, both long-term and short-term links exist. The other key aspect considered in this analysis is the stock market integration in Eastern European countries. Our analysis shows that the integration of the stock markets in Eastern European countries seems to be rather week except for the Hungarian stock market. This means that only the Hungarian stock market is integrated. A standard regression analysis reveals that the Hungarian market exhibits a strong co-movement with the benchmark market, i.e. the German stock market. Furthermore, there is a clear-cut result with respect to the dynamic of stock market synchronization. The degree of synchronization increased particularly in the period 2005–2008.     

Private capital flows,stock market and economic growth in developed and developing countries: A comparative analysis

Empirically we investigate how three types of private capital flows could promote economic growth in recipient developed and developing countries. Our focus is on the role of stock markets as a channel through which foreign capital flows could promote growth. The findings reveal that FDI exhibits a positive impact on growth, while both foreign debt and portfolio investment have a negative impact on growth in all sample countries. However, our results indicate that stock markets might be a significant channel or leading institutional factor through which capital flows affect economic growth. The findings provide clear implications that the negative impact of private capital flows can be transformed into a positive one if the stock market development has attained a certain threshold level, regardless of whether it is in developed or developing countries.     

Determinants of Real Chinese GDP 1978–2014

In 2014, the IMF reported that China became the largest economy in the world according to Purchasing Power Parity rates. This study aims to explain the Chinese economic miracle. It focuses on frequently suggested factors influencing China’s real gross domestic product (GDP), such as export promotion, exchange rate policy, and foreign direct investment (FDI). The paper employs the Bounds test of the autoregressive distributed lag (ARDL) model to test for cointegration. Once cointegration is established, Granger Causality is investigated using the vector autoregressive model and the Toda and Yamamoto (1995) method. Two different combinations of the real macroeconomic variables exports, exchange rate, imports, and FDI were employed to examine Granger causal relationships. All explanatory variables, except for the exchange rate, were found to have plausible relationships with GDP. The exchange rate and GDP relationship was unexpected; a Renminbi appreciation was associated with an increase in GDP. To investigate this paradox, a third ARDL model was estimated with exports as the dependent variable and the exchange rate, world GDP, and FDI as the independent variables. In this model, we found evidence of cointegration and a plausible relationship between real exports and the real exchange rate. Exchange rate devaluation increased exports and thus indirectly increased GDP. Such findings help to resolve the unexpected results. Nonetheless, according to the Granger causality tests the established statistical evidence is rather weak. We found that both the exchange rate and FDI are no longer strong drivers of economic growth in China.     

Human Capital and FDI Inflows to Developing Countries: New Empirical Evidence

Despite the dramatic increase in total foreign direct investment (FDI) flows to developing countries in the last few years, the bulk of the inflows has been directed to only a limited number of countries. It has been argued that developing countries might enhance their attractiveness as locations for FDI by pursuing policies that raise the level of local skills and build up human resource capabilities. Nevertheless, the empirical evidence in the literature in support of this recommendation for a large sample of developing countries is scant. This paper evaluates this argument in the light of the evolution in the structural characteristics of FDI and empirically tests the hypothesis that the level of human capital in host countries may affect the geographical distribution of FDI. The empirical findings are: (a) human capital is a statistically significant determinant of FDI inflows; (b) human capital is one of the most important determinants; and (c) its importance has become increasingly greater through time.     

The Impact of Inflation Uncertainty on Output Growth and Inflation in Thailand*

We explore the impact of inflation uncertainty on output growth in Thailand, an emerging market economy with moderate inflation. Inflation and output uncertainty are modeled in a bivariate constant conditional correlation generalized autoregressive conditional heteroskedastic (AR(p)‐cccGARCH(1,1)) specification. We include the exchange rate in the mean equations, and use the headline and core inflation rates and industrial production to generate inflation and output uncertainty series. These series are then used in Granger causality tests to make inferences about the effect of monetary policy‐induced inflation uncertainty. Causality tests show a positive relation from inflation to inflation uncertainty. Additionally, increased inflation uncertainty decreases output. These results are consistent with real costs associated with moderate inflation. Finally, we find no evidence that monetary policy reduced these costs.     

Foreign Direct Investment and Trade Openness in Sub‐Saharan Economies: A Panel Data Granger Causality Analysis

This study uses annual balanced panel data for 25 sub‐Saharan African economies over the period 1977‐2009 to investigate the Granger causality relationship between trade openness and foreign direct investment (FDI) for the region. We took advantage of recent developments in econometric testing techniques for Granger noncausality heterogeneous panels that takes into consideration the effects of cross section dependence across the units of the panel data set to analyse the trade–FDI nexus in the region. The empirical result of this study reveals a bidirectional causal relationship between trade openness and foreign direct investment in sub‐Saharan economies. Concurrently, African countries should devote more emphasis for the promotion and attraction of FDI in order to expand their productive capacity to produce and export; in this way, by addressing supply‐side constraints, FDI will have positive multiplier effects on trade.     

The Effect of Inflation Targeting on Foreign Direct Investment Flows to Developing Countries

Due to the many benefits that come with foreign direct investment (FDI), such as greater economic growth and technology spillovers, developing countries strive to attract this type of investment. Although the amount of FDI in developing countries has increased greatly over the past several years, not all developing countries have been successful at attracting it. A credible monetary policy, such as inflation targeting (IT), might make countries that implement it more attractive destinations for FDI flows due to the reliable macroeconomic environment created. This paper estimates the effect of IT on FDI flows to developing countries using a difference-in-differences approach and panel data for 71 countries for the period 1985 to 2013. This paper also looks at the difference between targeting and non-targeting countries in terms of FDI inflows during times of high instability. The results indicate that the adoption of IT leads to increased FDI flows to developing countries overall and, most importantly, during times of distress.

     

Relationship between foreign capital flows,domestic investment and savings in the SADC region

The importance of foreign capital in the domestic economy cannot be underestimated as it bridges the gap between domestic capital demand and supply. Given this background the paper studies the relationship between the different types of foreign capital flows in the Southern Africa Development Region (SADC) region – foreign direct investment (FDI), remittances, cross border bank flows (CBF), overseas development assistance (ODA) – and domestic savings and investment, employing the panel cointegration test and the dynamic ordinary least squares method (DOLS). The empirical results reveal that there is a strong positive relationship between domestic investment and domestic savings, FDI and remittances. These findings indicate that FDI remittances help in overcoming the limits on the domestic capital formation in the SADC region through permitting a rate of investment which is in excess of that which can be generated by domestic savings. Important policy implications on attracting foreign capital flows are discussed in the paper.     

Capital flows and exchange rates: recent Korean and Taiwanese experience and challenges

We first study the characteristics of the financial crisis and its impacts on Taiwanese and Korean economies. We have examined 22 macroeconomic fundamentals, such as GDP, inflation rates, government budget, trade balance, external debt, money supply, and ratios of average monthly imports and cumulative inward portfolio investment to international reserves, and compared with an extensive data set of the two countries. The comparisons point out that the macrofundamentals of both countries are basically the same, except the international finance sector. After defining currency crisis and banking crisis, the causes of crises are identified as the nominal exchange rates and the short-term external debt-to-international reserves ratios. In view of this, we use cointegration and causality tests to examine the relationship between these two time series. We have found a unidirectional causality from the short-term debt ratio to the exchange rate for Korea, but no causality between the two for Taiwan. The paper ends with some discussions on the lessons and challenges from the experience of the two countries.     

The Impact of Corruption on the Black Market Premium

Recently the impact of institutional factors on macro variables has been gaining momentum. Researchers have investigated the impact of corruption, law and order, and bureaucracy on economic growth, inflation, investment, productivity, and the real exchange rate. In this article, we investigate empirically the impact of institutional factors on the black market premium. In many developing nations, because of government restrictions on capital and trade flows, there exists a black market for foreign exchange. By using data from 60 developing countries over the 1982-1995 period, we show that the black market premium is higher in countries that are plagued by more corruption. This finding seems to be insensitive to five different measures of corruption as well as whether cross-section or panel data are used.     

Do contagion effects exist in capital flow volatility?

The cross-border transmission of a financial shock has been a subject of rich literature. While a large number of studies have focused on the phenomenon of strong co-movements of asset prices and capital flows in the event of financial stress, very few discussed the contagion or spillover effects in terms of capital flow volatility. This paper is one of the first attempts to assess, empirically, whether or not there is a global and regional spillover effect in the volatility of capital flows to emerging and developing countries. Based on the sample of 49 emerging and developing countries for the period 1980–2009, the empirical results suggest strong and significant contagion effects in the volatility of capital flows to individual economies. The magnitudes of contagion vary depending on the type of capital flows, whether it is foreign direct investment (FDI) or portfolio and other investment (mostly bank lending). The findings also suggest the volatility dynamics of gross flows is different from that of net flows. The volatility of net inflows is more exposed to intra-regional contagion compared to that of gross inflows.     

The Interactions of Stock Prices and Exchange Rates in the ASEAN-5 Countries: New Evidence Using a Bootstrap Panel Granger Causality Approach

Abstract

Using a data-set from the ASEAN-5 countries over the January 2000–August 2013 period, this paper revisits the Granger causal nexus between the equity and foreign exchange markets by employing the bootstrap panel Granger causality approach developed by Kònya, which allows for both cross-sectional dependency and heterogeneity across countries. The results indicate a unidirectional causality from stock prices to exchange rates in Malaysia, the Philippines and Thailand and from exchange rates to stock prices in Indonesia. These findings have important implications for policy-makers and institutional investors who should rigidly monitor the dynamic linkages between stock price and exchange rate movements across the ASEAN-5 financial markets when making policy decisions and investing in these countries.     

Foreign Direct Investment and Trade: A Causality Analysis

In this article, we analyze the relationship between outward foreign direct investment (FDI) and exports, using Spanish quarterly data for the period 1977–1998, by means of Granger causality tests in a cointegration framework. Our results point to the existence of a relationship of complementarity between both variables, with Granger causality running in the short run from outward FDI to exports, and bilateral Granger causality in the long run.
