Many studies have found that international borders represent large barriers to trade. But how do international borders compare to domestic border barriers? We investigate international and domestic border barriers in a unified framework. We consider a unique data set of exports from individual...

Das ifo Institut hat im Auftrag des Bundesministeriums für Wirtschaft und Technologie die vorliegende Evaluierungsstudie zu den Dimensionen und Auswirkungen eines Freihandelsabkommen zwischen der EU und den USA durchgeführt. Die Studie zeigt, dass ein tiefgreifendes...

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. However, these models tend to rely heavily on symmetry assumptions and assume melting iceberg transport costs as the only form of trade restrictions. Moreover, a standard...

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers. However, it is typical in many of these...

Trade data are typically reported at the level of regions or countries and are therefore aggregates across space. In this paper, we investigate the sensitivity of standard gravity estimation to spatial aggregation. We build a model in which initially symmetric micro regions are combined to form...

Sectoral concentration of exports has been a longstanding matter of concern for policymakers in developing countries. According to the economic theory and recent empirical evidence, improved market access through trade arrangements is likely to favor export diversification. In this paper, we...

Borders have a sizable negative impact on trade flows. Given the vast number of individual goods potentially traded, this "border effect" could have two possible explanations: (1) less international than domestic trade in the goods that are actually traded between countries ("flow"), or (2)...
