Casual empiricism suggests that additive trade costs, such as quotas, per-unit tariffs, and, in part, transportation costs, are prevalent. In spite of this, we have no broad and systematic evidence of the magnitude of these costs. We develop a new empirical framework for estimating additive...

This paper estimates the effect of trade policy during the Great Liberalization of the 1990s on innovation in over 60 countries using international firm-level patent data. The empirical strategy exploits ex-ante differences in firms' exposure to countries and industries, allowing us to construct...
