Regional financial integration in the GCC

We investigate the extent of regional financial integration in the member countries of the Gulf Cooperation Council. Interest rate data show that convergence exists and that interest rate differentials are relatively short-lived—especially relative to other unified currency area and comparable to those of the Euro Area post 1999. Equity data using cross-listed stocks confirm that stock markets are fairly integrated compared to other emerging market regions, although price equalization is hampered by market illiquidity. The limited volume data available suggests that intra-GCC capital flows are sizeable.     

Foreign equity flows and the “Size Bias”: Evidence from an emerging stock market

This paper examines foreign investors' equity-level transactions in an emerging stock market, the Istanbul Stock Exchange, for the period 1997–2008 to derive insights into the debate on information asymmetries between domestic and foreign investors and the home bias puzzle. The analysis suggests two important findings. First, foreign investors do not consider the market portfolio of domestic securities as predicted by standard theories of international portfolio diversification. Second, the firm's size and the expected return are central to explain foreign investors' equity trades. The results are consistent with models based upon the hypothesis of differential information between foreign and domestic investors.     

Valuation effects with transitory and trend productivity shocks

Changes in asset prices of a country's foreign assets and liabilities (“valuation effects”) are commonly thought of as stabilizing: they counteract current account movements and mitigate the impact of the current account on the country's net foreign asset (NFA) position. This paper shows that whether valuation effects are stabilizing or not depends critically on the nature of the underlying productivity shocks. In response to transitory shocks, valuation effects are stabilizing; but in response to trend shocks, such effects amplify the impact of the current account on NFA position. These contrasting effects arise because optimally smoothing consumers respond differently to a transitory shock than to a trend shock to income. This theoretical result finds empirical support with G7 countries' data, and is illustrated by the pattern of external imbalances between the U.S. and other G7 countries since the 1990s.     

International capital flows

The surge in international asset trade since the early 1990s has lead to renewed interest in models with international portfolio choice. We develop the implications of portfolio choice for both gross and net international capital flows in the context of a simple two-country dynamic stochastic general equilibrium (DSGE) model. We focus on the time-variation in portfolio allocation following shocks, and resulting capital flows. Endogenous time-variation in expected returns and risk, which are the key determinants of portfolio choice, affect capital flows in often subtle ways. The model is consistent with a broad range of empirical evidence. An additional contribution of the paper is to overcome the technical difficulty of solving DSGE models with portfolio choice by developing a broadly applicable solution method.     

Tariff wars in the Ricardian Model with a continuum of goods

This paper describes strategic tariff choices within the Ricardian framework of Dornbusch, Fischer, and Samuelson (1977) using CES preferences. The optimum tariff schedule is uniform across goods and inversely related to the import demand elasticity of the other country. In the Nash equilibrium of tariffs, larger economies apply higher tariff rates. Productivity adjusted relative size (≈ GDP ratio) is a sufficient statistic for absolute productivity advantage and the size of the labor force. Both countries apply higher tariff rates if specialization gains from comparative advantage are high and transportation cost is low. A sufficiently large economy prefers the inefficient Nash equilibrium in tariffs over free trade due to its quasi-monopolistic power on world markets. The required threshold size is increasing in comparative advantage and decreasing in transportation cost. I discuss the implications of the static Nash-equilibrium analysis for the sustainability and structure of trade agreements.     

Stock market correlations between China and its emerging market neighbors

We examine interlinkages of stock return behavior for China and three emerging market neighbors from the Asia Pacific region from November 1993 to July 2008. Results are based on a VAR model. Impulse responses and vector decomposition of VAR are also utilized. Evidence suggests that the aggregate markets are mostly not interrelated. However, we observe relations between China and the other markets when foreign investor returns are specifically accounted for. In addition, a shock originating in China is significantly felt in the other equity markets. Stock market characteristics and macroeconomic conditions of these countries may help explain the observed relations.     

Exporting out of poverty: Provincial poverty in Vietnam and U.S. market access

Can a developing country reduce poverty by gaining increased market access to a large, rich country? The 2001 U.S.–Vietnam Bilateral Trade Agreement (BTA) provides an excellent opportunity to examine this question as, unlike other bilateral trade agreements, the U.S. tariff cuts were not influenced by Vietnamese industries. Using variation in the structure of the labor force across provinces prior to the trade agreement, I construct provincial measures of U.S. tariffs. To address concerns over confounding trends between changes in provincial poverty and changes in provincial tariffs I follow two approaches: controlling for trends based on observable initial conditions and differencing away time invariant trends using pre-BTA data. I find that provinces that were more exposed to the U.S. tariff cuts experienced faster decreases in poverty between 2002 and 2004. Additionally, I document that the movement of workers across provinces is limited in scale, particularly for those with low levels of education. Finally, I show that the most exposed provinces experienced faster wage growth for workers with low levels of education, but not for highly educated workers.     

Gravity, trade integration, and heterogeneity across industries

We derive a micro-founded measure of bilateral trade integration that is consistent with a broad range of leading gravity models. This measure accounts for cross-industry heterogeneity by incorporating substitution elasticities estimated at the industry level. We then use it to provide a theory-based ranking of trade integration across manufacturing industries in European Union countries. In addition, we explore the determinants of trade integration, finding that substantial Technical Barriers to Trade in certain industries as well as high transportation costs associated with heavy-weight goods are the most notable trade barriers.     

Relationship between portfolio diversification and value at risk: Empirical evidence

This research explores the risk associated with the stocks prices in the seventeen selected companies that are listed in Indian BSE (100) National as well as portfolios of investment that are constructed from these seventeen companies employed. Additionally, for considering the possibility of international diversification, construction of portfolios of investment form stock price indexes in various emerging markets and developed countries of the world is considered. Correlations for domestically as well as internationally diversified portfolios are computed to unveil the relationship between stock prices of various firms as well as domestic and internationally diversified portfolios of investments. Further, to understand the effect of diversification on the risk associated with each of the portfolios of investments employed, value at risk analysis (VaR) is undertaken for studying the benefits associated with domestic as well as international diversification (if any).The study results show that domestic diversification lowers the expected losses associated with each of the domestic portfolios of investment employed where the international diversification substantially mitigates the portfolio risks. Results from VaR analysis reveal that diversification lowers the portfolio risks and additional reduction in portfolio risks is realized by international diversification.     

Estimating vertical spillovers from FDI: Why results vary and what the true effect is

In the last decade, more than 100 researchers have examined productivity spillovers from foreign affiliates to local firms in upstream or downstream sectors. Yet results vary broadly across methods and countries. To examine these vertical spillovers in a systematic way, we collected 3626 estimates of spillovers and reviewed the literature quantitatively. Our meta-analysis indicates that model misspecifications reduce the reported estimates and journals select relatively large estimates for publication. No selection, however, was found for working papers. Taking these biases into consideration, the average spillover to suppliers is economically significant, whereas the spillover to buyers is statistically significant but small. Greater spillovers are received by countries that have underdeveloped financial systems and are open to international trade. Greater spillovers are generated by investors who come from distant countries and have only a slight technological edge over local firms.     

Does corporate governance risk at home affect investment choices abroad?

Disparity between control and ownership rights gives rise to the risk of tunneling by the controlling shareholder, and is prevalent in many emerging market economies and present in some developed countries. At the same time, international investors come from different countries whose home markets are characterized by varying degrees of control–ownership disparity. This paper studies whether this difference in investors' home countries affects their portfolio choice in an emerging market. It combines two unique data sets on ownership and control in business groups, and investor-stock level foreign investment in Korea. A key finding is that investors from low-disparity countries disfavor high-disparity stocks in Korea, but investors from high-disparity countries are indifferent. Moreover, investors from low-disparity countries became averse to disparity only after the Asian financial crisis. These results suggest that the nature of corporate governance in international investors' home countries affects their portfolio choice abroad, and therefore these investors should not be lumped together in the analyses of their portfolio choice.     

Geographical focus in emerging markets and hedge fund performance

Emerging market hedge funds are an asset class which does not seem to outperform the market benchmarks. We hypothesize that the poor aggregate performance may be due to lack of focus of these funds. Our results suggest that a portfolio of emerging market hedge funds, which have geographical focuses, outperform their underlying stock markets. Hedge funds which focus on Eastern Europe appear to have the best outperformance. However, we also find that the performance of all emerging market hedge funds has reduced after the start of the 2008 Crisis.     

The impact of trade liberalization on productivity: Evidence from India's formal and informal manufacturing sectors

Despite a large literature investigating the impacts of trade on firm productivity, there is almost no evidence on how small firms react to trade liberalization. Using a unique dataset of firm-level surveys that are representative of the entire Indian manufacturing industry, I show that India's unilateral reduction in final goods tariffs increased the average productivity of small, informal firms, which account for 80% of Indian manufacturing employment but have been excluded from previous studies. In contrast, the increase in productivity among larger, formal firms was driven primarily by the concurrent reduction in input tariffs. By examining the effect of the tariff liberalization on the distributions of productivity and firm size, I find evidence consistent with the exit of the smallest, least productive firms from the informal sector. In addition, I find that although the decline in final goods tariffs did not significantly impact average formal sector productivity, it did increase productivity among the top quantiles of the distribution.     

Plant-level responses to antidumping duties: Evidence from U.S. manufacturers

This paper describes the effects of a temporary increase in tariffs on the performance and behavior of U.S. manufacturers. Using a dataset that includes the full population of U.S. manufacturing plants, I show that an apparent positive correlation between antidumping duties and traditional revenue productivity is likely misleading. For the subset of plants reporting quantity-based output data, increases in prices and markups artificially inflate the effect of antidumping duties on revenue productivity, while physical productivity actually falls. Moreover, antidumping duties allow low-productivity plants to continue producing protected products, slowing the reallocation of resources from less productive to more productive uses.     

Financial liberalization, structural change, and real exchange rate appreciations

The last twenty years have witnessed periods of sustained appreciations of the real exchange rate in emerging economies. The case of Mexico between 1988 and 2002 is representative of several episodes in Latin America and Central and Eastern Europe in which countries opening to capital flows experienced large appreciations accompanied by a significant reallocation of workers towards the non-tradable sector. We account for these facts using a two sector dynamic general equilibrium model of a small open economy with frictions to labor reallocation and two driving forces: (i) A decline in the cost of borrowing in foreign markets, and (ii) differential productivity growth across sectors. These two mechanisms account together for 60% of the decline in the domestic relative price of tradables in Mexico and for a large fraction of the observed reallocation of labor across sectors. The decline in the interest rate faced by Mexico in international markets is quantitatively the most important channel. Our results are robust to the inclusion of terms of trade into the model.     

Treasury Bond risk and return, the implications for the hedging of consumption and lessons for asset pricing

All consumption-based models of asset pricing imply that the relation between the conditional mean and conditional volatility of any asset reflects the effectiveness of holding that asset as a hedge against intertemporal variation in the marginal utility of consumption. For Treasury Bonds of various maturities, we find significant positive relations. Our empirical findings support the conclusion that investors must sell bonds short to hedge shocks to marginal utility, because realized bond returns tend to be high (low) when investors least (most) desire an additional dollar of consumption. Implications for special cases of the general consumption-based model are also discussed.     

Political cycles under external economic constraints: Evidence from Cyprus

This paper examines the presence of political cycles in a small open economy using data from Cyprus over the period 1978–2006, and explores their conditionality upon external economic constraints, such as globalization and European integration. Two basic results emerge. First, we find evidence of partisan shifts in economic policies and outcomes, although these effects seem to decrease as globalization progresses, and to disappear in the run-up to EMU. This implies that, while partisan cycles can emerge under a certain domestic political setting, the sensitivity of an economy to globalization pressures and the challenges resulting from EU/EMU membership can lead to their weakening. Second, we find evidence of electoral shifts in certain, more visible, subcomponents of the fiscal balance. However, in contrast to partisan distinctions, these opportunistic effects become more pronounced as globalization proceeds. It seems that constraints imposed on the ability of politicians to ingratiate themselves with partisans, may actually strengthen their incentives to engage in electioneering.     

The specific factors continuum model, with implications for globalization and income risk

This paper embeds the specific factors model in the goods continuum approach of Dornbusch et al. (1977, 1980) and applies it to analyze the effect of globalization on income risk. Globalization amplifies sector specific income risk induced by idiosyncratic sectoral technology shocks, but tends to reduce income risk to both mobile and immobile factors induced by aggregate technology shocks that differ by country. Aggregate risk bears most heavily on the poorest specific factors.     

Exposure to foreign media and changes in cultural traits: Evidence from naming patterns in France

Free trade in audio-visual services has faced opposition on the grounds that foreign media undermine domestic culture, and ultimately, global diversity. Using a long panel of French birth registries, we assess the media–culture link using name frequencies as a measure of tastes. Controlling for the number of people who currently have a name and unobserved name effects, our regressions show that media influences choices via selective imitation. Parents are much more likely to adopt media names that they associate with youth. Using estimated parameters, we simulate our model of name choice to reveal that, absent foreign media, fewer than 5% of French babies would have been named differently. Our simulations also suggest a positive effect of foreign media on the welfare of parents.     

Currency crises with the threat of an interest rate defence

While virtually all currency crisis models recognise that the decision to abandon a peg depends on how tenaciously policy makers defend it, this is seldom modelled explicitly. We add the threat of an interest rate defence to the global game model of Morris and Shin (American Economic Review 88, 1998). With an endogenous defence, actions of speculators may become strategic substitutes instead of the usual complements. Nevertheless, our generalised model remains tractable and has a unique threshold equilibrium. It provides additional insights. For instance, the threat of an interest rate defence makes speculation riskier and this may be sufficient to keep speculators out when fundamentals are still relatively strong.
