This thesis examines the impact of institutions, especially the financial institutions, on international trade and foreign direct investments. The first four chapters study the financial institutions and their impact on trade and international specialization. Specifically, the first chapter...

This chapter focuses on the estimation and interpretation of gravity equations for bilateral trade. This necessarily involves a careful consideration of the theoretical underpinnings since it has become clear that naive approaches to estimation lead to biased and frequently misinterpreted...

We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...

This paper introduces quality innovations with endogenous sunk costs in a heterogeneous firm model of international trade and derives implications for the gravity equation. The model predicts that the effect of fixed costs on exports and on the share of exporters is lower in industries with a...

Activists denouncing firms for what they consider unethical conduct (e.g., poor treatment of labor or practices that are harmful to the environment) often pressure firms through consumer boycotts. This paper presents a model of international trade with heterogeneous firms and endogenous...

This paper develops a methodology for trade policy analysis of costs and benefits of alternative regional integration scenarios, based on the disaggregated gravity equation, and applies it to calculate the impact of the EU enlargement on integration strategies of non-member countries. In...

In this thesis, I dealt with the question if the so-called 'New New Trade Theory' can also be applied to the agricultural sector, and if so, which recommendations arise. The thesis consists of five discussion papers dealing with a special problem each. While the first two papers focus on...
