Banks should evaluate whether a borrower is likely to default. I apply several techniques in the extensive mathematical literature of stochastic optimal control/dynamic programming to derive an optimal debt in an environment where there are risks on both the asset and liabilities sides. The...

A healthy financial system encourages the efficient allocation of capital and risk. The collapse of the house price bubble led to the financial crisis that started in 2007. There is a large empirical literature concerning the relation between asset price bubbles and financial crises. I evaluate...

It has been argued that increased life expectancy raises the rate of return on education, causing a rise in the investment in education followed by an increase in lifetime labor supply. Empirical evidence of these relations is rather weak. Building on a lifecycle model with uncertain longevity,...

We provide a model with endogenous portfolios of secured and unsecured household debt. Secured debt is collateralized by owner-occupied housing whereas unsecured debt can be discharged according to bankruptcy regulations. We show that the calibrated model matches important quantitative...

Women born in 1935 went to college significantly less than their male counterparts and married women's labor force participation (LFP) averaged 40% between the ages of thirty and forty. The cohort born twenty years later behaved very differently. The education gender gap was eliminated and...

Over the last three decades, average income for the bottom half of the US distribution increased by 8% while their average saving rate decreased by eight percentage points. Over the same period the US experienced a substantial increase in inequality and a continuous decrease in the aggregate...

This paper shows that optimal unemployment insurance contracts are age-dependent. Older workers have only a few years left on the labor market prior to retirement. This short horizon implies a more digressive replacement ratio. However, there is a sufficiently short distance to retirement for...

The labor market effects of pension reform stem from retirement behavior and from job search and hours worked of prime age workers. This paper investigates the impact of four often proposed policy measures for sustainable pensions: strengthening the tax benefit link, moving from wage to price...

The Pessimists and the Optimists disagree whether the US external deficits and the associated buildup of US net foreign liabilities are problems that require urgent attention. A warning signal should be that the debt ratio deviates significantly from the optimal ratio. The optimal debt ratio or...
