"Do Trade Agreements Actually Reduce Trade Volatility?" with Josh Ederington and Yoonseon Han (July 2021 version)
ABSTRACT: A frequently stated objective of regional and multilateral trade agreements is to stabilize trade and reduce volatility in trade flows. We examine whether trade agreements accomplish this goal. Using a structural gravity approach we identify two potential channels through which international trade institutions may influence the volatility of bilateral trade flows: by affecting the variance of trade barriers and by affecting the covariance of economic outcomes between the trading partners. We then use a panel of bilateral industry-level trade data to empirically examine the effects of regional trade agreements and GATT/WTO membership on export earnings volatility. We find some evidence that joining a multilateral trade agreement such as the GATT does make export earnings less volatile. However, we find that signing a regional trade agreement actually increases measured volatility in bilateral exports and that this increase in volatility increases as the trading partners become more integrated.
