We argue that geographical clustering helps the weakest firms to survive. We model this neglected negative externality by adapting the heterogeneous firms model of Melitz (2003) to include firms that invest in R&D and firms that do not. Separating the chance of post-entry market exit into a...

This paper examines the interactive effect of distance and trade on international conflict and cooperation. The effect of geographic distance depends on trade, while the effect of trade varies with geographic distance. Trade reduces conflict to a greater extent when dyads are geographically...

We develop a multicountry model in which governments aim at excessive spending in order to serve the narrow interests of the group in power. This puts pressure on the monetary authorities to extract seigniorage, and thus affects the incentives countries would have to participate in a monetary...

This paper examines the potential advantages and disadvantages of adopting a common currency arrangement among the six IMF member Pacific island countries that have their own national currency. These countries are Fiji, Papua New Guinea, Samoa, Solomon Islands, Tonga, and Vanuatu. The study...

This Selected Issues paper analyzes the income dispersion and comovement in the Eastern Caribbean Currency Union region. It finds that incomes are diverging, with the Leeward Islands converging to a higher income level than the Windward Islands. The paper examines the macroeconomic impact of...

This paper discusses key findings of the Cluster Report on German-Central European Supply Chain (GCESC). Since the 1990s, a GCESC has evolved, manufacturing goods for export to the rest of the world. Reflecting this, bilateral trade linkages between Germany and the Czech Republic, Hungary,...

This study considers the role of export diversification in determining trade outcomes during the global financial crisis. The impact of export diversification (or concentration) is measured by assessing three different dimensions of specialization. First, concentration by geographic destination...

Using US firm level panel data we simultaneously assess the contributions to productivity of three potential sources of research and development spillovers: geographic, technological, and product market ("horizontal"). To do so, we construct new measures of geographic proximity based on the...

We investigate whether the supply of venture capital (VC) is driven by spatial proximity between a VC company and the portfolio firm. Our analysis is based on information about VC investments in Germany between 2004 and 2009. We find that possible problems caused by the geographic distance to a...

The objective of this article is to examine the diffusion of spillovers within technological cooperation. More precisely, we shall ask to what extent permanent geographic proximity, defined, as co-location by the geography of innovation, is really necessary to benefit from spillovers when agents...
