Two recently improved sets of cross-country panel data are combined in order to re-examine the effects of population growth and fertility on economic growth. Using a 107 country panel data set covering 1960-85, we find that high birth rates appear to reduce economic growth through investment...

This paper examines theory and evidence from recent studies into the contributions to economic growth of expenditure on education and on research and development. Investment in human capital has fundamentally different economic attributes to physical investment - exhibiting complementarity,...

Popularity is self reinforcing. The attention garnered by popular options propels further interest in them. Yet rather than blindly follow the crowd, most pay attention to how well these items match their tastes. We model this role of social learning in guiding selective attention and market...

We develop an analytically tractable Phillips curve based on state-dependent pricing. We differ from the existing literature by considering a local approximation around a zero inflation steady state and introducing idiosyncratic shocks. The resulting Phillips curve is a simple variation of the...

How significant are individual differences in self-control? Do these differences impact wealth accumulation? From where do they derive? Our survey-based measure of self-control provides insights into all three questions: 1.There are individual differences in self-control not only of a...

We present a model of the market for used cars in which agents face a fixed cost of adjustment, the magnitude of which depend on the degree of adverse selection in the secondary market. We find that, unlike typical models, the sS bands in our model contract as the variance of the shock process...

Prior research has established that consumption falls significantly at retirement. What is not known is the extent to which this fall is anticipated during the working years. Do working households expect such a large fall in consumption upon retirement, or are they taken by surprise? Using data...

In welfare theory it is standard to pick the consumption stream that maximizes the welfare of the representative agent. We argue against this position, and show that a benevolent social planner will generally place a greater weight on future consumption than does the representative agent. Our...

The theoretical relationship between investment and uncertainty is ambiguous. This paper briefly surveys the insights that theory has to offer and then runs a series of simple tests aimed at evaluating the empirical significance of various theoretical effects. Our results from a panel of U.S....

We show that a straight forward approximation of the distribution of durable goods holdings gives rise to a tractable equilibrium (S,s) model of durable demand. We analyze both competitive and monopoly supply. We show that equilibrium interactions lead to elongated impulse responses in demand,...
