Non-parametric gravity as defined in this paper encompasses previous parametric forms. The model generates non-parametric sufficient statistics for arbitrage gains from trade and terms of trade, and a non-parametric elasticity of terms of trade with respect to supply. For world manufacturing...

Nearly half of all transactions in the $5 trillion market for manufactured goods in the United States were intermediated by wholesalers in 2012, up from 32 percent in 1992. Seventy percent of this increase is due to the growth of "superstar" firms - the largest one percent of wholesalers....

This study empirically investigates how the invoice currency choice differs between intra-firm and arm's-length exports. We also examine whether other firm- and product-level characteristics affect the choice of invoice currency. This study is the first to be granted access to highly...

We build an equilibrium model of a small open economy with labor market frictions and imperfectly enforced regulations. Heterogeneous firms sort into the formal or informal sector. We estimate the model using data from Brazil, and use counterfactual simulations to understand how trade affects...

Building on Eaton and Kortum's (2002) model of Ricardian trade, Alvarez and Lucas (2005) calculate that a small country representing 1% of the world's GDP experiences a gain of 41% as it goes from autarky to frictionless trade with the rest of the world. But the gains from openness, which...

In a model where all factors of production are imperfectly mobile, we argue that the Dixit-Norman scheme of commodity taxes may not lead to strict Pareto gains from trade. Rather, this scheme must be augmented by policies which give factors an incentive to move: hence, the role for trade...

We challenge the conventional wisdom on the variety and productivity gains from trade liberalization which are commonly referred to as "new" gains from trade. In particular, we show that the import variety gains measured in studies such as Broda and Weinstein (2006) are counteracted by exactly...

We develop a general equilibrium model of monopolistic competition and trade based on indirectly additive preferences and heterogenous firms. It generates markups independent from destination population but increasing in destination per capita income, as documented empirically. Trade...

Uneven development within countries suggests that domestic trade frictions are important. Trade flows within a country, however, are rarely observed. We employ a new dataset on trade between fifteen Chinese treaty ports to examine the importance of domestic frictions around the year 1900. The...

In a standard multi-sector, heterogeneous-firm trade model the effect of tariffs on entry, especially in the presence of production linkages, can reverse the traditional positive optimal-tariff argument. We construct and employ a new, large, disaggregated tariff dataset and then apply a...
