Trade policy uncertainty (TPU) has become an important source of economic uncertainty and research. We review the main sources and measures of TPU. We then provide a conceptual framework for modeling TPU and methods for estimating and quantifying its effects. We analyze its role in trade...

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 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.

We estimate the impact of trade policy uncertainty (TPU) on CES import price indices, focusing on the implications of Britain's exit from the European Union (Brexit). Our analysis reveals that an increase in the probability of Brexit increases U.K. import price indices by raising the prices of...

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...
