This paper considers the effects of trade policy-tariffs and quotas-when importing is done by competitive traders who are identical ex ante but differ ex post. We show that the standard equivalence results no longer hold and the conventional ranking of tariffs and quotas is turned on its head:...

This paper provides a framework for understanding trade patterns in the Mashreq. An augmented gravity model is used to compare actual with expected levels of trade. Trade barriers, political uncertainty, and over-appreciation of domestic currencies seem to explain low levels of international...

Using firm-level data for Estonia for the years 1997-2005, we analyze the impact of international competition on firm dynamics, considering both firm closedown and product switching. We contribute to the literature in two important ways: (1) this is the first paper to study the determinants of...

While global rebalancing will mainly involve structural realignment among major advanced and emerging market economies, it could have significant impact on low-income countries (LICs). Simulations using a global general equilibrium model show that a more balanced global economy would tend to...

In most macroeconomic models, the substitutability between domestic and foreign goods is calibrated using aggregated data. This imposes homogeneous elasticities across goods, and the calibration is only valid under this assumption. If elasticities are heterogeneous, the aggregate...

Index number theory informs us that if data on matched prices and quantities are available, a superlative index number formula is best to aggregate heterogeneous items, and a unit value index to aggregate homogeneous ones. The formulas can give very different results. Neglected is the practical...

We examine the effect of tariff policies on evasion of customs duties, in the context of the trade reform in India of the 1990s. We exploit the variation in tariff rates across time and products to identify the evasion elasticity, namely, the effect of tariffs on evasion, and relate this...

This Working Paper brings together three papers prepared as background for discussions at the Second High-Level Conference on Asian Integration cohosted by the Monetary Authority of Singapore and the IMF on May 25, 2006. The first documents recent trends in the intraregional flow of goods and...

Despite the appreciation of the exchange rate, the eight Central and Eastern European countries (the CEE-8) that entered the European Union in May 2004 have achieved a decade of impressive export growth, expanding significantly their shares of world markets. Does this mean that the real exchange...

This paper finds that the estimates of Armington elasticities (the elasticity of substitution between groups of products identified by country of origin) obtained from multilateral trade data can differ from those obtained from bilateral trade data. In particular, the former tends to be higher...
