During World War I (1914–1918) the birth rates of countries such as France, Germany, the U.K., Belgium and Italy declined by almost 50 percent. The age structure of these countries’ populations were significantly affected for the duration of the 20th century. In France, where the population...

During World War I (1914–1918) the birth rate in France fell by 50%. The corresponding deficit of births is estimated at 1.4 million, while military losses are estimated at 1.4 million too. Thus, the fertility decline doubled the demographic impact of the war. I construct a model of fertility...

We study the optimal auditing of a taxpayer’s income in a dynamic principal-agent model of hidden income. Taxpayers in our model initially have low income and stochastically transit to high income that is an absorbing state. A low-income taxpayer who transits to high income can under-report...

This thesis applies mechanism design to explore the roles of outside and inside money in achieving optimal allocations. Two chapters use settings that are related to random-matching models. The third uses an overlapping generations setting. In all three, a critical role is played by assumptions...
