A trade union whose purpose is to raise wages above the competitive level may foster economic growth if it succeeds in shifting income away from the owners of capital to the workers and if the workers' marginal propensity to save exceeds that of capitalists. We make this point in an overlapping...

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor...

The paper surveys and extends recent results on the effect of changes in government fiscal and financial policy, and in private savings behaviour, on economic growth. Private saving behaviour is represented by an overlapping generations (OLG) model. The supply side of the model permits...

We develop a simple growth model with imperfect competition in which demand conditions can affect the dynamics of capital accumulation, hindering or enhancing growth. In our model the elasticity of the demand schedule faced by a typical firm depends on the aggregate savings rate. The latter...

This paper employs cohort technique and Consumer Expenditure Survey data to construct average age-profiles of consumption and income over the working lives of typical households across different education and occupation groups. Using these profiles, we estimate a structural model of optimal...

One of the basic motives for saving is the accumulation of wealth to insure future welfare. Both introspection and extant research on consumption insurance find that people face substantial risks that they do not fairly pool. In theory, the consumption and wealth accumulation of price-taking...

This Paper introduces state dependent utility into the standard Mehra and Prescott (1985) economy by allowing the representative agent’s coefficient of relative risk aversion to vary with the underlying economy’s growth rate. Existence of equilibrium is proved and its asymptotic properties...

This Paper analyses dynamic equilibrium risk sharing contracts between profit-maximizing intermediaries and a large pool of ex-ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex-post. In any given period, after having observed their income, the...

Government spending at the zero lower bound (ZLB) is not necessarily welfare enhancing, even when its output multiplier is large. When government spending provides direct utility to the household, its optimal level is at most 0.5-1 percent of GDP for recessions of -4 percent; the numbers are...

Almost half of American families did not adjust their consumption following receipt of the 2001 or 2008 tax rebates. Another 20%, with low income and more likely to rent, spent a small but significant amount. Households with large spending propensity held high mortgage debt. The heterogeneity is...
