We present an international trade model of multiproduct firms where firms differ in their endowment of managerial resources and in how effectively these resources can be used in making production more efficient. The model gives rise to a trade-off between conglomerate and specialization...

This paper calls into question the currently most influential model of international trade. An empirical finding by Trefler (2004, AER) and others that industrial productivity increases more strongly in liberalized industries than in non-liberalized industries has been widely accepted as...

We develop a theory of multiproduct firms to analyze the effects of globalization on the distributions of firm size, scope, and productivity. In the model, firms are heterogeneous in how well they cope with expanding their product range. The model generates a negative relationship between firm...

The aim of this paper is to study the spatial selection of firms once it is recognized that heterogeneous firms typically choose different locations in respond to market integration of regions having different sizes. Specifically, we show that decreasing trade costs leads to the gradual...

How does trade liberalization affect wages? This is the first paper to consider in theory and data how the impact of final and intermediate input tariff cuts on workers’ wages varies with the global engagement of their firm. Our model predicts that a fall in output tariffs lowers wages at...

Business cycle fluctuations in developed economies (N) tend to have large and persistent effects on developing countries (S). We study the transmission of business cycle fluctuations for developed to developing economies with a two-country asymmetric DSGE model with two features: (i) endogenous...

We use 6-digit bilateral trade data to document the effect of WTO/GATT membership on the extensive and intensive product margins of trade. We construct gravity equations for the two product margins where the specifications of these gravity equations are motivated by the model of Eaton and Kortum...

We study international trade in a model where consumers have non-homothetic preferences and where household income restricts the extensive margin of consumption. In equilibrium, monopolistic producers set high (low) prices in rich (poor) countries but a threat of parallel trade restricts the...

This paper documents that debt and equity issuance are procyclical for most size-sorted firm categories of listed U.S. firms. The procyclicality of equity issuance decreases monotonically with firm size. At the aggregate level, however, the results are not conclusive. The reason is that issuance...

We merge German balance-of-payments and foreign-affiliate-trade statistics to obtain data about trade in commercial services at the firm level. We use these data to study export market participation and the choice of export mode: cross-border versus foreign-affiliate sales. We find that for...
