We propose a simple model of a mating economy in both monogamous and polygynous cultures, and derive implications for how polygyny affects individual and aggregate fertility. We find that an attractive woman is more likely to find a high-status husband. However, when polygyny is allowed,...

The paper presents empirical evidence of AIDS epidemic effects on demography variables and accumulable factors. Using a panel of 47 Sub-Saharan African countries, we show that AIDS has negative and significant effect on life expectancy and fertility rate. Thus, a one percent increase in AIDS...

This paper presents a simulation framework developed to assess the impact of ageing on the financial sustainability of the Czech pension system. It accompanies the publication OECD Reviews of Pension Systems: Czech Republic. The framework has two components: a macroeconomic model to project...

In this paper, we first, perform a quantitative assessment of the impact of the HIV/AIDS epidemic on growth. Second, we precisely account for the effects of the epidemic on income per capita through human and physical capital accumulations, population and labor force. That is, we disentangle the...

This paper aims at quantifying the macroeconomic and distributional impacts of product market reforms and additional public investment using a DSGE model. The model reflects specific features of the South African economy. Tradable and non-tradable product markets are modelled separately, and a...

Productivity growth has been falling for a decade, hindering improvements in living standards. Low productivity reflects, firstly, poor infrastructure in telecommunications and transport. Secondly, the regulatory environment is not always business-friendly and often raises obstacles to firm...

We analyze the implications of communitarianism-the tendency of people to organize into separate culturally homogeneous groups-for individual and group inequality in human capital accumulation. We propose a non-cooperative social interactions model where each individual decides how much time to...

More than half of the HIV/AIDS-infected population today are women. We study a dynamic model of (in)fidelity, which explains the HIV/AIDS gender gap by the configuration of sexual networks. Each individual desires sexual relationships with opposite sex individuals. Two Markov matching processes...
