-Maximilians-Universität München. It includes six self-contained chapters which deal with the following topics in empirical international trade and …, trade, and informal employment as illustrated by the maquiladora industry in Mexico (chapter 4), the interaction between … migration and trade and their effects on unemployment (chapter 5), and the dynamics of democracy and income chapter 6). …

Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on … international trade flows, and the well-known - and traditionally presumed exogenous – “trade-cost elasticity” plays a central role … in computing general equilibrium trade-flow and welfare effects of trade-cost changes. This paper addresses theoretically …

trade and derives implications for the gravity equation. The model predicts that the effect of fixed costs on exports and on … aggregate trade data and firm-level data to estimate gravity equations and find strong evidence for a dampening effect of … vertical differentiation on the fixed costs elasticity in international trade. Moreover, we estimate the parameters of our …

, interconnections among countries can no longer be adequately assessed through standard bilateral gross trade flows and new methods of … analysis are needed. In this paper, we compute measures of network analysis and apply visualisation tools to value added trade … (value added flows). The analysis is extended beyond total trade flows to discuss the distinct roles of goods and services in …

Building on a heterogeneous-firm model à la Melitz (2003), we propose a theory of intermediaries in international trade … result, validated on Italian firm-level trade data, is consistent with productivity sorting in the export mode and with the …

costs indicate that a large share of the simulated increase in trade is attributable to declines in the firm's entry cost …

We study how financial frictions affect firm-level heterogeneity and trade. We build a model where productivity …

a trade model with heterogeneous exporters and endogenous quality choice. The model predicts that financial development …

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments … turn, lower emissions per output. We show that the overall effect of trade is to reduce emissions. Trade weeds out some of … to more productive and cleaner exporters. The overall effect of trade is therefore to reduce emissions. We test empirical …
