Barriers to international trade are known to be large. But have they become smaller over time? Building on the gravity framework by Anderson and van Wincoop (2003), I derive an analytical solution for time-varying multilateral resistance variables that can be related to observable trade data....

International trade costs are of vital importance because they determine trade patterns and therefore economic performance. This paper develops a new micro-founded measure of international trade costs. It is based on a multi-country general equilibrium model of trade that incorporates bilateral...

Trade costs are known to be a major obstacle to international economic integration. Following the approach of New Open Economy Macroeconomics, this paper explores the effects of international trade costs in a micro-founded general equilibrium model that also allows for pricing to market. Trade...

This paper derives a micro-founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and rich substitution patterns across goods. In contrast to standard CES-based gravity equations, trade is more sensitive to trade costs if the...

Barriers to international trade are known to be large but due to data limitations it is hard to measure them directly for a large number of countries over many years. To address this problem I derive a micro-founded measure of bilateral trade costs that indirectly infers trade frictions from...
