I model life expectancy in terms of physical and human capital and technology, the fundamental economic variables described by economic growth theories. For concreteness, the Solow model and a convergence club growth model by Howitt and Mayer (2001) are used as examples. I discuss how a multiple...

Globalization has drastically improved access of technological latecomers to advanced technologies and provides a unique opportunity for low-income countries to raise per capita income. This paper shows that low-income countries as a group have in fact substantially increased the GDP-ratio of...

The paper analyses credibility and reputation in the context of peace negotiations. Where war provides economic gains to one side, peace is not incentive compatible, and peace agreements will necessarily degenerate, as they become time inconsistent. Levels of conflict are an increasing function...

The standard method of testing for efficient risk-sharing in village economies does not allow one to identify vulnerable households, only to make statements about the average risk in the village, or of sub-groups identifiable on the basis of observables. Here, by working directly with...
