We use individual and multi-level data from Zambia on child nutritional health to test the absolute income hypothesis (AIH), the relative income hypothesis (RIH) and the income inequality hypothesis (IIH). The results confirm a non-linear positive relation between economic resources and health,...

We show theoretically that the poor can benefit from price changes induced by higher income inequality. As the number of poor in a society increases, or when the income difference between rich and poor increases, the market for products aimed towards the poor grows and such products become more...

We use the Economic Freedom Index (Gwartney, Lawson and Norton 2008) to characterise the institutions of ancient Athens in the fourth century BCE. It has been shown that ancient Greece witness improved living conditions for an extended period of time. Athens in the classical period appears to...

Both institutional quality and institutional stability have been argued to stimulate economic growth. But to improve institutional quality, a country must endure a period of institutional change, which implies at least a little and possibly a lot of institutional instability. We investigate the...

This paper analyzes the relation between three dimensions of globalization (economic, social and political) and life expectancy using a panel of 92 countries over the period 1970-2005. Using different estimation techniques and sample groupings we find a very robust positive effect from economic...

The standard method when analyzing the problem of cooperation using evolutionary game theory is to assume that people are randomly matched against each other in repeated games. In this paper we discuss the implications of allowing agents to have preferences over possible opponents. We model...

Private universities, as opposed to publicly financed ones, are dominant in some countries and almost non-existent in others. We develop a dynamic model to demonstrate that private providers emerge as soon as they can profitably sell an elite signal to the most highly talented. As private...

We analyze a cooperation game and a coordination game in an evolutionary environment. Agents make noisy observations of opponent's propensity to play dove, called reputation, and form preferences over opponents based on their reputation. A game takes place when two agents agree to play. Socially...

Using the newly developed KOF-index of globalization, as well as the economic freedom index from the Fraser institute, we examine if globalization and economic liberalizations are linked to increases in income inequality within countries. Studying changes between 1980 and 2000, we find a...

We analyze a cooperation game in an evolutionary environment. Agents make noisy observations of opponents’ propensity to cooperate, called reputation, and form preferences over opponents based on their reputation. A game takes place when two agents agree to play. Pareto optimal cooperation is...
