Our purpose in this paper is to present a class of convex endogenous growth models, and to analyze their performance in terms of both growth and business cycle criteria. The models we study have close analogs in the real business cycle literature. In fact, we interpret the exogenous growth rate...

Our aim in this paper is to exposit a convex model of equilibrium growth. The model is strictly in the Solow tradition. The model has two features which distinguish it from most other work on the subject. These are, first, that the model is convex on the technological side and, eecond, that...

The most recent addition to the economics of gloom concerns the interplay between income and environmental degradation. The main question raised is whether or not continued environmental degradation is a necessary part of the process of industrialization. Will pollution continue to increase...

The recent literature an endogenous growth models has emphasized the effect that the rate of return has an the capital accumulation decisions and, consequently, on the growth rate of the economy. In most cases the basic model is a variant of the representative agent growth model. The key feature...

In this paper we study how volatility in monetary policy affects economic performance in the presence of endogenously chosen information structures. To isolate the effects produced by the interaction of uncertainty in monetary policy and (possibly) asymmetric information, we consider a model in...

In this chapter we revisit the relationship between income and fertility. There is overwhelming empirical evidence that fertility is negatively related to income in most countries at most times. Several theories have been proposed in the literature to explain this somewhat puzzling fact. The...

This paper develops a model of HIV diffusion among heterosexual individuals who choose (i) whether to engage in sex, i.e. the source of potential infection, (ii) the nature of their relationship as measured by the endogenous rate of partnership destruction, (iii) the presence of extra-marital...

We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in...

We develop a model that accounts for several stylized facts about immigrant earnings. First, it implies that new immigrants learn less than natives with the same level of schooling. Second, depending on the age of immigration, it implies that initially, immigrant earnings need not grow faster...
