The constraints that external linkages impose on domestic policy choices in Saudi Arabia have continuously evolved over the past four decades. This paper argues that two major ongoing developments in particular have affected and will continue to affect policy trade-offs. First, growing oil needs...

In this paper we estimate gravity models to see whether trade volumes of countries in the MENA region are significantly lower than what would be expected given their economic, cultural and geographical characteristics. Our empirical results show that the variables used in standard gravity models...

This paper develops a full-fledged cost-benefit analysis of monetary integration, and applies it to the currency unions actively pursued in Africa. The benefits of monetary union come from a more credible monetary policy, while the costs derive from real shock asymmetries and fiscal disparities....

In most macroeconomic models, the substitutability between domestic and foreign goods is calibrated using aggregated data. This imposes homogeneous elasticities across goods, and the calibration is only valid under this assumption. If elasticities are heterogeneous, the aggregate...

The paper develops a tractable way to incorporate the micro structure of dual models of international trade into a standard class of dynamic open-economy macro models. In the process, it develops the concept of a dynamic factor price equalization set and an integrated intertemporal equilibrium....

This paper examines the structural competitiveness of oil-rich economies in sub-Saharan Africa relative to other major oil-exporting developing countries, and investigates reasons for systematic differences in the non-oil export performance across these economies. The analysis reveals that...
