This paper presents new estimates of the economic benefits from economic and political integration. Using the synthetic counterfactuals method, we estimate how GDP per capita and labour productivity would have behaved for the countries that joined the European Union (EU) in the 1973, 1980s, 1995...

We show that relaxing the assumption of CES preferences in monopolistic competition has surprising implications when trade is restricted. Integrated and segmented markets behave very differently, the latter typically implying a form of reciprocal dumping. Globalization and lower trade costs have...

This paper surveys the theoretical and empirical literature on the relationship between the spatial distribution of economic activity and transportation costs. We develop a multi-region model of economic geography that we use to understand the general equilibrium implications of transportation...

This article analyzes the stability of bimetallism for countries operating in integrated bullion markets who enact different legal ratios. I articulate a new theoretical framework to demonstrate that two countries can both be bimetallic only if they coordinate their legal ratios. The theoretical...

We characterize how firms select between alternative ways of serving a market. ``First-order" selection effects, whether firms enter or not, are extremely robust. "Second-order" ones, how firms serve a market conditional on entry, are less so: more efficient firms will select into the entry mode...

We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. We highlight how various economic...

This paper introduces scale economies or density economies in transportation in a trade and geography model with heterogeneous firms. This relatively small change to the standard model produces a new pattern of spatial sorting among firms. Contrary to the existing literature, our model produces...

We use a version of the Melitz (2003) model to calibrate the magnitude and impact of the border effect, the well-known empirical regularity that trade is much lower across a national border than would otherwise be expected. We calibrate total bilateral trade frictions as a parameter and show...

We quantify the causal effect of foreign investment on total factor productivity (tfp) using a new global firm-level database. Our identification strategy relies on exploiting the difference in the amount of foreign investment by financial and industrial investors and simultaneously controlling...

Rapid economic growth in some emerging economies in recent decades has significantly increased their global economic importance. If this rapid growth continues and is strongest in resource-poor Asian economies, the growth in global demand for imports of primary products also will continue, to...
