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.     

Analysing interconnectivity among economies

As international financial integration gathers pace, interconnectivity has increased tremendously among financial institutions, financial markets and financial systems, a phenomenon to which the recent global financial crisis perhaps provided the best testimony. The interconnectivity among financial entities at various levels is multilateral in dimension and highly complicated with numerous feedback loops. To contribute to the understanding of the complexity of the global financial system, this study shows how the interconnected relationships can be disentangled into simple and quantifiable bilateral interdependence linkages, using 11 Asia-Pacific economies as an example. A major finding is that all these economies register a significantly higher sovereign risk once the condition that another economy is in distress is imposed.     

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.     

Monetary autonomy in emerging market economies: The role of foreign reserves

This paper examines trends in monetary autonomy and their interactions with financial integration, currency regimes and foreign reserves for recent decades in emerging Asian and Latin American economies. Our main findings are the following: First, most emerging Asian economies have increased monetary autonomy mainly due to changes in currency regimes toward floating regimes, while emerging Latin American economies have shown mixed results on monetary autonomy. Second, in all sample economies, the accumulation of foreign reserves has contributed to retaining monetary autonomy, probably implying the role of foreign reserves as an anchor for monetary autonomy in emerging market economies.     

Competition for firms in an oligopolistic industry: The impact of economic integration

We set up a model of generalised oligopoly where two countries of different size compete for an exogenous, but variable, number of identical firms. The model combines a desire by national governments to attract internationally mobile firms with the existence of location rents that arise even in a symmetric equilibrium where firms are dispersed. As economic integration proceeds, equilibrium taxes initially decline, but then rise again as trade costs fall even further. A range of trade costs is identified where economic integration raises the welfare of the small country, but lowers welfare in the large country.     

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.     

Housing wealth effect in emerging economies

In this paper I estimate the impact of changes in real and financial wealth on private consumption for a panel of 17 emerging economies from Asia and Central and Eastern Europe. Households' consumption, income and the two measures of real and financial wealth – proxied by house and stock market prices – are found to be difference-stationary and co-integrated; by means of recent econometric techniques for heterogeneous panels, i.e. the pooled mean group estimator, inference is drawn about the long- and short-run relationships between the variables of interest. The main result of the analysis shows that both real and financial wealth positively affect households' consumption in the long-run, with the elasticity of housing wealth being larger than that of stock market wealth. Moreover, there is also a significant short-run adjustment from income, stock prices and house prices on consumption, i.e. consumption adjusts to its long-run relationship with lags. When the model is run for the two groups of countries separately, the long-run impact of an increase (decrease) in house prices is generally higher in Central and Eastern European economies with respect to Asian ones, which make them more vulnerable to further adverse housing market developments.     

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.     

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.     

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.     

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 real effects of financial integration

This paper shows how correlations in GDP fluctuations rise with financial integration. Finance serves to increase international correlations in both consumption and GDP fluctuations, which explains the persistent gap between the two in the data, a “quantity puzzle”. The positive association between financial integration and GDP correlation constitutes a puzzle, as theory suggests a negative relation if anything. Nevertheless, it prevails in the data even after the effects of finance on trade and specialization are accounted for.     

The Competitiveness of European Financial Markets

The countries that together make up the euro area are undergoing a process of far-reaching change, with established national financial markets merging into one new European market accompanied by deregulation, cross-border consolidation, and increased competition within the euro area. These developments will help to increase longterm economic growth and will have a strong bearing on the international competitiveness of the European financial sector, leading to innovation and modernisation. This paper presents the underlying rationale of financial integration and increased competitiveness of European financial markets and provides a snapshot of where financial integration has been successful and where work is ongoing. It also notes important historical experiences of U.S. financial integration. It concludes by highlighting the role and recent activities of the European Central Bank and the Eurosystem in promoting and enhancing further financial integration. JEL Classification F15, G15     

Foreign exchange market liberalization and the international diversification of borrowing by Italian firms

In this article we try to assess the relative importance of real and financial determinants in firm's foreign currency borrowing by extending a model earlier developed by Kawai. We use this framework to examine the behavior of Italian firms during the 1980s. The financial components of firm's decisions are studied by means of a repeated mean-variance portfolio model based on ex ante expectation. We show that (a) the invoice currencies seem to be a good indicator of firm's real exchange risk; and (b) even at times of capital controls, corporate debt policy was affected by financial variables. The latter will become increasingly important as European financial integration moves on.     

Who's afraid of a globalized world? Foreign Direct Investments, local knowledge and allocation of talents

We study the distributional effects of globalization within a model of heterogeneous agents where both managerial talent and knowledge of the local economic environment are required in order to become a successful entrepreneur. Agents willing to set up a firm abroad incur a learning cost that depends on how different the foreign and domestic entrepreneurial environments are. In this context, we show that globalization fosters FDI and raises wages, output and productivity. However, not everybody wins. The steady state relationship between globalization and income is U-shaped: high- and low-income agents are better off in a globalized world, while middle-income agents (domestic entrepreneurs) are worse off. Thus, consistently with recent empirical evidence, the model predicts globalization to increase inequality at the top of the income distribution while decreasing it at the bottom.     

Testing for convergence in bank efficiency: a cross-country analysis

This paper empirically investigates a possible convergence among the operational efficiency of financial institutions across countries. We explore (i) the relative performance of banking industries in two samples (European and global) over time, and (ii) whether banking industries are likely to attain the same level of efficiency in the long run as implied by international financial integration. We find that convergence in bank efficiency is incomplete and limited to European banking industries. Differing level of bank efficiencies across the globe may offer opportunities for international investors who would like to capitalize on such market imperfections. Our findings also have implications for policy makers who are concerned with the full integration and the stability of the global financial system.     

Measuring financial market integration in the European Union: EU15 vs. New Member States

This paper quantifies financial market integration in the European Union, using a large array of credit and bond market indicators, stock market indicators, as well as indicators based on household and firm decisions. It focuses on comparing the evolution of the European Union before the Eastern enlargement (EU15) with that of the 12 New Member States (NMS) that joined after 2000. It documents improvements in the integration of the credit and bond markets as well as stock markets for both groups within the EU27, the heightened heterogeneity brought about by the NMS, but also a reversal of the integration process over the recent years (corresponding to the financial crisis), divergence disrupting both the EU15 core and the NMS. For all the decades of achievements within both the EU15 and NMS groups in terms of credit and stock market integration, the ultimate goals of financial market integration, perfect capital mobility and full international risk sharing remain out of reach.     

Foreign subsidization and excess capacity

The U.S. steel industry has long held that foreign subsidization and excess capacity has led to its long-run demise, yet no one has formally examined this hypothesis. In this paper, we incorporate foreign subsidization considerations into a model based on Staiger and Wolak's (1992) cyclical dumping framework and illustrate testable implications of both cyclical excess capacity and structural excess capacity stemming from foreign subsidization. We then use detailed product- and foreign country-level data on steel exports to the U.S. market to estimate these excess capacity effects. While the full sample results provide evidence of both cyclical and structural excess capacity effects for exports to the U.S. market, these effects are confined to such a narrow range of country–product combinations that it is unlikely that such effects were a significant factor in the fortunes of U.S. steel firms over the past decades.     

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.
