This dissertation was prepared as a collection of 4 research articles in the field of international trade with a focus on gravity modeling and estimation for international trade and migration and on domestic firm-level labor market effects of internationalization. Chapter 2 structurally...

Although economists have long been interested in the implications of Marshallian externalities (i.e., industry-level external economies of scale) for trading economies, the large number of equilibria that they typically imply has kept such externalities out of the recent quantitative trade...

This paper studies linearized spatial structural gravity models of bilateral trade à la Behrens, Ertur and Koch (2012). We show that these models do in fact not require spatial econometric methods for estimation. This result follows from the nature of the specific spatial weights matrix, and...
