We develop a new general equilibrium monopolistic competition model with variable demand elasticity, heterogeneous firms, and multiple asymmetric regions. Wages, productivity, consumption diversity, and markups across firms and markets are all endogenously determined and respond to trade...

The Trans-Pacific Partnership (TPP) agreement, now in negotiation among nine Asia-Pacific countries, could yield annual global income gains of $295 billion (including $78 billion for the United States) and offers a pathway to free trade in the Asia-Pacific with potential gains of $1.9 trillion....

We analyze the decline in the U.S. share of world merchandise exports against the backdrop of a model-based measure of competitiveness. We preliminarily use constant market share analysis and gravity estimations to show that the majority of the decline in export shares can be associated with a...

We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selection into trade, while accommodating asymmetries in trade flows. A new equation for the proportion of exporting firms takes a gravity form, such that the extensive margin is also affected by...

We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. First, we solve a stylized 2x2 trade model of a large open economy and show that (a) productivity gains via exports and imports both reduce the strategically optimal...

This Working Paper estimates the effects of the Trans-Pacific Partnership (TPP) using a comprehensive, quantitative trade model, updating results reported in Petri, Plummer, and Zhai (2012) with recent data and information from the agreement. The new estimates suggest that the TPP will increase...

The paper investigates the costs and benefits of 2004 EU enlargement from the standpoint of Ukraine - a country that has been left behind. This angle allows estimating the costs of non-integration that occurred due to trade diversion and forgone opportunity to carry our structural changes in the...

Abstract: This paper applies a two stage estimation procedure that accounts for a sample-selection bias and firm-level heterogeneity in order to estimate a gravity model of exports at industry level of aggregation for 119 exporting countries and 142 importing countries in 2002-2006. It further...

Mainstream economic wisdom favoring cooperative free trade is challenged by a wave of disruptive trade policies. In this paper, we provide quantitative evidence concerning the economic impacts of tariffs implemented by the United States in 2018 and the subsequent retaliations by partner...
