International capital flows,returns and world financial integration

International capital flows have increased dramatically since the 1980s, with much of the increase being due to trade in equity and bond markets. Such developments are often attributed to the increased integration of world financial markets. We present a model that allows us to examine how greater integration in world financial markets affects the behavior of international capital flows and financial returns. Our model predicts that international capital flows are large (in absolute value) and very volatile during the early stages of financial integration when international asset trading is concentrated in bonds. As integration progresses and households gain access to world equity markets, the size and volatility of international bond flows decline. This is the natural outcome of greater risk sharing facilitated by increased integration. This pattern is consistent with declining volatility observed during 1975–2007 period in the G-7 countries. We also find that the equilibrium flows in bonds and stocks predicted by the model are larger than their empirical counterparts, and are largely driven by variations in equity risk premia. The model also predicts that volatility of equity and bond returns decline with integration, again consistent with the data for G-7 economies.     

Financial crises and contagion vulnerability of MENA stock markets

This paper examines contagion vulnerability and the international and regional financial linkages of the MENA stock markets. The degree of vulnerability of those markets to global and regional financial crises will have important bearings on the respective economies' growth rate, and on their ability to diversify international and regional portfolios. Granger causality tests and impulse response functions reveal that while the GCC equity markets still offer international investors portfolio diversification potentials, those markets are relatively less vulnerable to global and regional financial crises. Moreover, even though the remaining MENA stock markets of Egypt, Morocco, and Tunisia have matured and are now financially integrated with the world stock markets, they tend to exhibit more vulnerability to regional and international financial crises. Their vulnerability to international financial crises is due, on the one hand, to weak regional integration, and to greater economic and financial integration with the more advanced economies on the other.     

Global Volatility and Forex Returns in East Asia*

During 2001–2010, increases in mature market volatility were associated with declines in forex returns for East Asian economies, consistent with an overall ‘flight to safety’ effect. Estimates from GARCH models suggest that a 10 percentage point increase in mature market equity volatility generated an exchange rate depreciation of up to 3/4 percent. This sensitivity rose during a more tranquil subsample for some countries, reflecting their greater integration with global financial markets. Long‐run forex volatility increased in Asian economies after 2008, reflecting the global reach of the financial crisis in mature markets. Unconditional standard deviations estimated from these models provide operational measures of ‘long‐term’ and ‘excess’ volatility in forex markets.     

Exploring International Investment Through a Classroom Portfolio Simulation Project

A rapid integration of financial markets has prevailed during the last three decades. Investors are able to diversify investment beyond national markets to mitigate return volatility of a “pure domestic portfolio.” This article discusses a simulation project through which students learn the role of international investment by managing their own portfolios. The article explains the project's investment ground rule, trading requirement, and grading rubric. The students are required to examine many important factors in international business such as currency risks and regional policies. The structure of this project can also be applied to a course involving student-managed investment funds.     

Volatility,global information,and market conditions: a study in futures markets

This study examined the behavior of return volatility in relation to the timing of information flow under different market conditions influenced by trading volume and market depth. We emphasized information flow during trading and nontrading periods that may represent domestic and offshore information in the global trading of currencies. Test results show that volatility was negatively related to market depth; that is, deeper markets had relatively less return volatility. Additionally, the effect that market depth had on volatility was superseded by information within trading volume. Test results focusing on the timing of information flow reveal that in low‐volume markets, the volatility of nontrading‐period returns exceeded the volatility of trading‐period returns. However, when trading volume was high, this pattern was reversed and conformed to the observations of earlier articles. Our findings proved to be robust across time, different currency markets, and different measures of return volatility. We also observed a trend toward greater integration between foreign and U.S. financial markets; the U.S. market increasingly emphasized information from nontrading periods to supplement information arriving during trading periods. © 2001 John Wiley & Sons, Inc.

Aid,Aid Volatility and Sectoral Growth in Sub-Saharan Africa: Does Finance Matter?

This article examines the impact of aid and its volatility on sectoral growth by relying on panel dataset of 37 sub-Saharan African (SSA) countries for the period 1983–2014. Findings from the system-generalized methods of moments show that, while foreign aid significantly drives sectoral growth, aid volatility deteriorates sectoral value additions impacting heavily on non-tradable sectors with no apparent effect on the agricultural sector. The deleterious effect of aid volatility on sectoral value additions in SSA is weakened by a well-developed financial system with significant impact on the tradable sector. Evidently, development of domestic financial markets enhances aid effectiveness.     

Consumption smoothing,risk sharing and financial integration

Theories indicate that financial integration should allow economies to better share risk and thus improve consumption smoothing. We construct two widely used price‐based measures of financial integration (i.e., the standard correlation and the adjusted R‐squared) and test whether consumption volatility declines as international equity markets become more integrated. Pooled and panel estimates for three different groups of countries (i.e., G7, G20 and EU) provide no significant evidence of improved consumption smoothing as financial integration rises. This evidence is supported by a battery of robustness checks and holds over time. Taken together, our results suggest that convergence in international equity prices does not necessarily represent the channel through which risk‐sharing opportunities arise or consumption smoothing improves.     

Financial Integration in East Asia: An Empirical Investigation

The central objective of this paper is to empirically evaluate the degree of linkages among East Asian equity and bond markets. Using data from the IMF’s Coordinated Portfolio Investment Survey (CPIS), we find that intra‐East Asian financial asset holdings of four East Asian countries – Japan, Korea, Hong Kong and Singapore – are larger than the levels predicted by the financial gravity model. However, our analysis suggests that this result is likely to be driven by intra‐regional trade linkages and reflect those linkages. Therefore, the salient implication for regional policymakers is that they should continue to promote intra‐regional financial integration. This paper also aims to analyse the impact of three different types of country‐specific risks – political, economic and financial risks – on investment from the four countries. This analysis yields a clear positive relationship between destination‐country risk, in particular political risk, and capital inflows.     

How do trade and financial integration affect the relationship between growth and volatility?

The influential work of Ramey and Ramey [Ramey, G., Ramey, V.A., 1995. Cross-country evidence on the link between volatility and growth. American Economic Review 85, 1138-1151 (December).] highlighted an empirical relationship that has now come to be regarded as conventional wisdom—that output volatility and growth are negatively correlated. We reexamine this relationship in the context of globalization—a term typically used to describe the phenomenon of growing international trade and financial integration that has intensified since the mid-1980s. Using a comprehensive new data set, we document that, while the basic negative association between growth and volatility has been preserved during the 1990s, both trade and financial integration significantly weaken this negative relationship. Specifically, we find that, in a regression of growth on volatility and other controls, the estimated coefficient on the interaction between volatility and trade integration is significantly positive. We find a similar, although less robust, result for the interaction of financial integration with volatility.

Financial Globalisation and Emerging Markets Volatility

The volatility of capital flows to emerging market (EM) countries and frequency of financial crises have imposed high welfare costs on the countries involved. The empirical literature provides, at best, a mixed picture on the relationship between long‐run EM country growth and financial integration. Meanwhile, the prevailing policy discourse regarding reform of the international financial system remains incomplete: the focus has largely been on either institutional and policy measures required of EM countries or international crisis‐resolution procedures. The role played by private financial markets and institutions in the developed world has not received adequate attention. This paper describes some of the structural features inherent in today's financial markets that directly contribute to the instability in EM capital flows.     

Global and regional range-based volatility spillover effects

This study extends the univariate Weibull conditional autoregressive range (CARR) model to establish a bivariate Weibull CARR (BWCARR) model to investigate the range-based volatility spillover effect. The empirical results indicate that a conditional autoregressive range relationship exists on the US, Japan, mainland China, Hong Kong and Taiwan stock markets. The new BWCARR model is more credible and efficient than the CARR model. Moreover, the range-based volatility for the US and Japan has an impact on Taiwan, indicating that there exists a range-based global and regional stock market spillover effect that has an impact on the Taiwanese stock market.     

The Effect of 2008 Crisis on the Volatility Spillovers among Six Major Markets

The scope of this paper is to determine whether global stock markets function differently under conditions of economic crisis by measuring volatility spillovers between six major markets, namely the US, the UK, Germany, Spain, Turkey, and Greece. We examine the volatility spillover effects of the 2008 US financial crisis to these six major markets using daily stock returns from January 2003 to December 2014, before, during, and after the 2008 financial crisis. We combine the Diebold and Yilmaz methodology with the stochastic volatility model of Taylor implemented through the sequential Efficient Importance Sampling method of Richard and Zhang to obtain variance decompositions derived from an estimated vector autoregressive model. The empirical findings suggest that stock markets tend to show increased volatility spillovers during the crisis period, thus resulting in lesser diversification benefits for investors.     

Foreign investment,regulation and price volatility in South-east Asian stock markets

This paper examines the extent to which changes in the openness of three South-east Asian Stock Markets to foreign investors impact on the volatility of prices in those markets. Regulatory authorities have been cautious about the opening up of markets to foreign investors, fearing that increased liberalisation may lead to increased price volatility, which, in turn, may have a detrimental effect on the operation of the market and the wider economy. Using an asymmetric GARCH model, it is shown that while greater liberalisation has changed the nature of price volatility in the markets, there has not been a destabilising impact. Rather, asymmetric responses of volatility to news have reduced post-liberalisation, suggesting that informed traders are playing a greater role in the markets, with the impact of noise traders being reduced.     

Modelling spillovers between stock market and FX market: evidence for Nigeria

Abstract

The need to capture the foreign exchange (FX) and stock markets nexus in Nigeria is underscored by the rapidly expanding financial markets integration due to trade and financial liberalization policies which seem to have enhanced the inflow of capital as well as accelerated investment/business interactions. Using variants of the VARMA-AMGARCH model of McAleer, Hoti, and Chan (2009), we find that volatility persistence in the stock market is accentuated by bad news in the market and moderated by good news in the FX market. Finally, we establish that ignoring the asymmetric effects may exaggerate the spillover results.     

A tripartite inquiry into volatility-efficiency-integration nexus - case of emerging markets

The objective of this paper is to analyse the time-varying changes of the three parameters, volatility, efficiency and integration on stock markets across emerging markets. We do this using a four-step process with focus on Multifractal Detrended Fluctuation Analysis to measure its efficiency. Our analysis show that lower volatility was found in short-term for countries that experienced fast paced economic growth. This increase in volatility is supported by a decrease in efficiency for the short-term, while market integration rose during periods of crises, which represent higher volatility. Hence, a tripartite relationship between our parameters is observed.

What Drives European Football Clubs’ Stock Returns and Volatility?

The article studies the main determinants of European football clubs’ stock returns and volatility. A panel-data analysis of a sample of 24 European football clubs was conducted to test the influence of several variables, based on a matrix of internal/external and real/financial dimensions, on both stock returns and their volatility. The results show that clubs’ stock returns are influenced by the real and financial context and by a set of internal variables such as profit considered as a reflection of accounting discipline, capitalization as an indicator of size and stadium attendance as a proxy indicator of reputation. The volatility of stock returns seems particularly vulnerable to the overall instability on stock markets and dependent on clubs’ profit and net players’ transfers and, to a lesser extent, on sporting outcomes.     

Understanding bilateral exchange rate volatility

This paper develops an empirical model of bilateral exchange rate volatility. We conjecture that for developing economies, external financial liabilities have an important effect on desired bilateral exchange rate volatility, above and beyond the standard optimal currency area (OCA) factors. By contrast, industrial countries do not face the same set of constraints in international financial markets. In our theoretical model, external debt tightens financial constraints and reduces the efficiency of the exchange rate in responding to external shocks. We go on to explore the determinants of bilateral exchange rate volatility in a broad cross section of countries. For developing economies, bilateral exchange rate volatility (relative to creditor countries) is strongly negatively affected by the stock of external debt. For industrial countries however, OCA variables appear more important and external debt is generally not significant in explaining bilateral exchange rate volatility.     

Options on federal funds futures and interest rate volatility

This study examines the response of the spot and futures interest rates on the fed funds, Eurodollar, and Libor to the listing of CME fed funds options. With the exception of the Libor futures, the introduction of options is associated with a decrease in the conditional volatility of the interest rates in the sample. There is also evidence that the volume of options trading has a negative effect on the fed funds and the Eurodollar spot rates. In contrast, the fed funds and the Eurodollar futures rates respond positively to the volume of options trading. Overall, strong generalization of the effects of options listing and options trading across the markets is not possible. These results remain robust even after controlling for several exogenous variables including changes in the Fed's target for the fed funds rate, the TED spread, the 9/11 terrorist attacks, and day‐of‐the‐week effects.
