The five chapters of this dissertation deal with the topic of trade under different kinds of uncertainty. In the first chapter, the impact of exchange rate uncertainty on exports of European countries is investigated with a special focus on short-term effects, sectoral differences and the impact...

This paper uses an augmented gravity model of trade to investigate the link between German development aid and sectoral exports from Germany to the aid recipient countries. The findings indicate that in the long run each dollar of German aid is associated with an average increase of 0.83 US...

The main aim of this paper is to investigate the political determinants of international arms transfers. We distinguish between the decision to exports arms (extensive margin) and the value of the arms exported (intensive margin). A theoretically-justified gravity model of trade augmented with...

The objective of this paper is twofold. First, it examines the effects of the implementation of trade facilitation (TF) measures on international trade flows and on participation in global value chains (GVCs). Second, it provides policy recommendations for developing Asia and the Pacific derived...

This paper investigates to what extent international migration can be explained by climatic variations. A gravity model of migration augmented with average temperature and precipitation in the country of origin is estimated using a panel data set of 142 sending countries for the period 1995 to...
