Does the pattern of social connections between individuals matter for macroeconomic outcomes? If so, where do these differences come from and how large are their effects? Using network analysis tools, we explore how different social network structures affect technology diffusion and thereby a...

We develop a tractable general theory for the study of the economic and demographic impact of epidemics. In particular, we analytically characterise the short and medium term consequences of epidemics for population size, age pyramid, economic performance and income distribution. To this end, we...

Food-for-work (FFW) programs are commonly used both for short-term relief and long-term development purposes. In the latter capacity, they are increasingly used for natural resources management projects. Barrett, Holden and Clay (forthcoming) assess the suitability of FFW programs as insurance...

In this world of plenty, almost half of the world's six billion people live on two dollars a day or less and the number living on less than one dollar a day has increased over the past fifteen years (World Bank 2000). Between one third and one half suffer undernutrition due to insufficient...

Using a simple theoretical model we conjecture that dual practice may increase the number of patients seen but reduce hours spent at public facilities, if public physicians lack motivation and/or if their opportunity costs are very large. Using data from Indonesia, we then test these theoretical...

Social institutions undoubtedly affect a country's economy. But how does this effect operate and how much does it matter for economic development? Using network analysis tools, we explore how different social structures might affect a country's rate of technological progress. The network model...

Many developing countries are plagued by persistent inequality in income distribution. While a growing body of economic-demographic literature emphasizes differential fertility channel, this paper investigates differential child mortality - differences in child mortality across income groups -...

Many doctors in developing countries provide considerably lower levels of quality to their patients than they have been trained to provide. The gap between best practice and actual performance is difficult to measure for individual doctors who differ in levels of training and experience and who...

We study the impact a redistribution of income has on the decisions of a health care innovator and the utility of consumers. We find that income redistribution from rich to poor increases the quality of the medical innovation, reduces its price and increases the utility of some of the consumers...

In many Western countries, the relative weight of people - measured by the Body Mass Index (BMI) - has increased substantially in recent years, leading to an increasing incidence of overweight and related health problems. As with many forms of risky behavior, it is plausible that overweight is...
