We examine how self-selection of workers into firms depends on the power of the firms' incentive schemes and how it affects the performance of firms that increase the power of the incentive schemes. In a laboratory experiment, we let subjects choose between (low-powered) team incentives and...

This paper investigates the effectiveness of an intervention that was targeted at a specific group of Dutch Social Assistance (SA) recipients with debt problems. With a large share of the income gains of work resumption were transferred to the creditors, these individuals experienced a strong a...

We specify a model for the lifetimes of spouses and the dynamic evolution of health, allowing spousal death to have causal effects on the health and mortality of the survivor. We estimate the model using a longitudinal survey that traces many health status aspects over time, and that is linked...

We provide evidence from a large-scale field experiment on the causal effects of audit rules on compliance in a market for long-term care. In this setting care should be provided quickly and, therefore, the gatekeeper introduced ex-post auditing. Our results do not show significant effects of...

This paper focuses on the relation between the onset of disability and employment outcomes. We develop an event history model that includes unscheduled hospitalizations as a measure for unanticipated health shocks and estimate the model on data from the British National Child Development Study...

We analyze the effect of economic conditions early in life on individual mortality rate later in life, using business cycle conditions early in life as an exogenous indicator. Individual records from Dutch registers of birth, marriage, and death, covering a window of unprecedented size...

This paper aims to assess the relative importance of differences in behaviouralresponses to financial incentives in explaining the observed variation in retirement behaviour across different types of households. We specify and estimate models for singles and married couples and estimate these on...
