Trade Policy Uncertainty
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 of estimating and quantifying its effects. We analyze its role in trade agreements and discuss open questions for future research.
