We provide theoretical and empirical evidence that policy uncertainty can significantly affect firm level investment and entry decisions in the context of international trade. When market entry costs are sunk, policy uncertainty can create a real option value of waiting to enter foreign markets...

We analyze the trade and production patterns of countries located at varying distances from an economic centre. Exports and imports of final and intermediate goods bear transport costs that increase with distance. We show how production and trade depend both on factor endowments and factor...

Most countries are members of preferential trade agreements (PTAs). The effect of these agreements has attracted much interest and raised the question of whether PTAs promote or slow down multilateral trade liberalization, i.e. whether they are a ‘building block’ or a ‘stumbling block’...

We assess the impact of U.S. trade policy uncertainty (TPU) toward China in a tractable general equilibrium framework with heterogeneous firms. We show that increased TPU reduces investment in export entry and technology upgrading, which in turn reduces trade flows and real income for consumers....

There has been an explosion in the number of preferential trade agreements (PTAs) in the last decade. PTAs are characterized by liberalization with respect to only a few partners and thus, they can potentially clash with and retard multilateral trade liberalization (MTL). Despite this important...

The theoretical debate over whether countries can and should set tariffs in response to export elasticities goes back over a century to the writings of Edgeworth (1894) and Bickerdike (1907). Despite the optimal tariff argument's centrality in debates over trade policy, there exists no evidence...

The proliferation of preferential trade liberalization over the last 20 years has raised the question of whether it slows down multilateral trade liberalization. Recent theoretical and empirical evidence indicates this is the case even for unilateral preferences that developed countries provide...
