To investigate how fertility rates interrelate with the modern economy, we construct a simple model in which variety expansion of consumption goods reduces fertility rates. In our model, variety expansion reduces the relative price of a composite of di?erentiated goods compared to child- rearing...

In this paper, we present a model in which agents choose voice, exit, or stay options when their marital condition becomes bad. The "voice" option can be interpreted as a spouse's effort or "investment" in the household to resolve his/her dissatisfaction and improve the marital condition. If a...

This article focuses on two distinct faces of globalization: the decrease in trade costs of goods and the decline of affiliation costs of joint ventures by foreign firms with local firms. The decrease of affiliation costs drives relocation of firms from the North to the South. When the market...

In this paper, we construct an interregional trade model that has en- dogenous fertility rates in the manner of Helpman and Krugman (1985). The presented model shows that fertility rates in a large region become lower than those in a small region because of the agglomeration of man- ufacturing...

This paper develops an overlapping generations model with technology choice and imperfect credit market, in order to investigate a possible source of underdevelopment. Consistent with empirical observations in the literature, the model shows that better financial institutions that provide...

This paper examines the movement of an individuals reservation level over time in a two-sided search model with two-sided imperfect self-knowledge, where agents are vertically heterogeneous and do not know their own types. Agents who do not know their own types update their beliefs about their...

This paper studies the problem of the long-run preferences distribution in a large population using an evolutionary approach. Special attention is given to the investigation of the property of the mixed population equilibria, in which materialists and reciprocators coexist. Some of the players...
