This book formulates the situation under which differential migration waves
of the genders to cities, coupled with potential wealth imbalances, can create an environment
that is conducive to the spread of HIV. The model of the marital market and the extra-marital
market presented in Chapter 2, which builds on this assumption and the fact that the
migration waves that are increasingly male-dominated create an excess demand for the
extra-marital market. In the model presented in this paper, homogenous agents make three
choices: choice of location, the decision to marry, and whether and how much they will
participate in the extra-marital market. In addition to showing the macro effects, the book
differentiates between the different agents to show the differential risk faced by the two
genders and agents which face different outcomes in the marital market.
