We consider trade liberalization in a multilateral trade model, where countries have identical homothetic tastes but may have different constant returns to scale technologies that produce at least two goods from at least two factors. In this model, we derive the world prices after trade...

Amid a general rise in protectionism and a trade war between the world's two largest economies, this paper analyzes changes in gains from trade for the world over a decade marked by rapid global economic integration preceding the global financial crisis of 2007-08. It employs state-of-the-art...

We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. We highlight how various economic...

This study considers endogenous determination of domestic standards on products that cause negative consumption externalities in the presence of a preferential trade agreement (PTA) in a three-country world. In particular, we examine how a PTA affects the optimal levels of external tariffs and...

The emergence of the People's Republic of China (PRC) as a great economic power has stimulated an epochal shift in patterns of world trade, accompanied by a remarkable level of internal migration within the country. Hundreds of millions of Chinese workers have moved from inland areas to coastal...

The present study develops an equilibrium displacement model (EDM) to evaluate the impacts of a free trade agreement (FTA) on the profits of individual farmers. The parameters representing the share of profit within revenue and the elasticity of cost with respect to quantity in the cost function...

We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...

Welfare with the maximum-revenue tariff is compared to free-trade welfare under perfect competition in the case of a large country able to affect its terms of trade; under Cournot duopoly with differentiated products; and under Bertrand duopoly with differentiated products. Under perfect...

This paper introduces a model of limited consumer attention into an otherwise standard new trade theory model with love-of-variety preferences and heterogeneous firms. In this setting, we show that trade liberalization needs not be welfare enhancing if the consumers' capacity to gather and...
