The literature on household asset accumulation draws a sharp distinction between "short-run" precautionary motives to buffer consumption from annual income shocks, and "long-run" life cycle considerations under income certainty. However, estimates of shock persistence imply considerable career...

Recent empirical studies suggest that the average marginal propensity to consume (MPC) has declined. This paper explains the declining trend of the MPC with a standard representative consumer model where borrowing constraints become more relaxed as suggested by data. With an increase in...

This paper examines aggregate savings in a general equilibrium model where infinitely lived households face volatile (and possibly uncertain) income paths, hold a risk-free asset, and face a borrowing constraint. I first show that the equilibrium capital stock in an economy without uncertainty,...

The well-documented positive correlation between income risk and wealth was interpreted as evidence for high amounts of precautionary wealth in various studies. However, the large estimates emerged from pooling non-entrepreneurs and entrepreneurs without controlling for heterogeneity. This paper...

Uncertainty concerning future income lowers consumption. This is often called the precautionary demand for savings. In this paper the existence of precautionary saving is investigated using Swedish data for the years 1973-1992. As there are no variables for consumers' uncertainty we use proxies....

In 1997 Chancellor Kohl proposed a major pension reform and pushed the law through Parliament explaining that the German PAYG system had become unsustainable. One limitation of the new law---one that is crucial for our identification strategy---is that it left the generous pension entitlements...

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 uses the British Household Panel Survey for the years 1996 to 2000 to investigate whether individuals in the UK save for precautionary motives against uncertain medical costs. In particular, we test the hypothesis that those individuals who are not covered by private medical...

This paper investigates if labour income uncertainty, particularly as related to the development and diffusion of fixed and short-term work contracts, may have played a role in determining the recent decline of the marginal propensity to consume of Italian households. We analyse this issue in...

How does risk affect saving? Empirical work typically examines the effects of detectible differences in risk within the data. How these differences affect saving in theoretical models depends on the metric one uses for risk. For labor-income risk, second-degree increases in risk require prudence...
