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...

In this model of education, where individuals are exposed both to educational risk and to wage risk within the skilled sector, successful graduation depends both on individual effort to study and on public resources. We show that insuring the present risks is a dichotomic task: Wage risk is...

This paper analyzes the welfare effects of the Italian social security system in an economy with uncertainty on wages, financial market returns and life expectancy. The introduction of a pension system reproducing the Italian statutory scheme turns out to decrease ex-ante individual welfare,...

This paper analyzes the optimal response of the social insurance system to a rise in labor market risk. To this end, we develop a tractable macroeconomic model with risk-free physical capital, risky human capital (labor market risk) and unobservable effort choice affecting the distribution of...

Courts typically base compensation for loss of income in personal injury cases on either mean or median work income. Yet, quantatively, mean and median incomes are typically very different. For example, in the US median income is 65 percent of mean income. In this paper we use economic theory to...

This paper shows that job mobility is a valuable channel which employed workers use to mitigate bad labor market shocks. I construct and estimate a model of wage dynamics jointly with a dynamic model of job mobility. The key feature of the model is the specification of wage shocks at the worker-...

Microeconomic theory predicts that under certain regularity conditions higher idiosyncratic risk increases the propensity to insure against independent marketable risks. We apply these predictions to the specific case of labor income risk and car insurance using data from the UK. The main...

We study workers' idiosyncratic earnings risk over the life-cycle using a German administrative data set. Positive and negative earnings shocks both contain a highly persistent component. The variance and average size of positive persistent shocks is decreasing over the life-cycle. The...
