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....

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...

The median landlocked country has only 30 percent of the trade volume of the median coastal economy. Halving transport costs increases that trade volume by a factor of five. Improving the standard of infrastructure from that of the bottom quarter of countries to that of the median country...

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

We estimate the uncertainty effects of preferential trade disagreements. Increases in the probability of Britain's exit from the European Union (Brexit) reduce bilateral export values and trade participation. These effects are increasing in trade policy risk across products and asymmetric for UK...

We examine the role of trade policy uncertainty in shaping the import decisions of firms. If the adoption of a new input requires a sunk cost investment, then the prospect of price increases in that input, e.g. due to trade barriers, reduces the adoption of that input (a substitution effect) and...

We estimate the impact of increased policy uncertainty from Brexit on UK trade in services. We apply an uncertainty-augmented gravity equation to UK services trade with the European Union at the industry level from 2016Q1 to 2018Q4. By exploiting the variation in the probability of Brexit from...

Why do governments employ inefficient policies to redistribute income towards special interest groups (SIGs) when more efficient ones are available? To address this puzzle we derive and test predictions for a set of policies where detailed data is available and an efficiency ranking is feasible:...

The theoretical debate over whether countries can and should set tariffs in response to the foreign export elasticities they face goes back to Edgeworth (1894). Despite the centrality of the optimal tariff argument in trade policy, there exists no evidence about whether countries actually...
