In most studies on individual labor market transitions, the search process leading to job offers is a black box. In this paper we specify and estimate a search model that distinguishes between formal (applications) and informal (referrals) search methods. Job offers can be obtained by either...

We prove identification of dependent competing risks models in which each risk has a mixed proportional hazard specification with regressors, and the risks are dependent by way of the unobserved heterogeneity, or frailty, components. We show that the conditions for non-parametric identification...

The results of studies exploring the long-term consequences of famine during foetal or infant development are inconsistent. We tested the hypothesis that selection forces occurring during a famine change the distribution of frailty in the affected cohorts, possibly hiding negative long-term...

Consider a setting where a treatment that starts at some point during a spell (e.g. in unemployment) may impact on the hazard rate of the spell duration, and where the impact may be heterogeneous across subjects. We provide Monte Carlo evidence on the feasibility of estimating the distribution...

We analyze causal effects of conditions early in life on the individual mortality rate later in life. Conditions early in life are captured by transitory features of the macro-environment around birth, notably the state of the business cycle around birth, but also food price deviations, weather...

We provide an empirical analysis of job mobility with heterogeneous firms and employees. Inference is Bayesian. The results indicate an unobserved heterogeneity at the level of the individuals, and even more influential at the firm level. Furthermore, assortative employers? and employees?...

Cognitive functioning of elderly individuals may be affected by events such as the loss of a (grand)child or partner or the onset of a serious chronic condition, and by negative economic shocks such as job loss or the reduction of pension benefits. It is conceivable that the impact of such...

Serious life events, such as the loss of a relative or the onset of a chronic condition may influence cognitive functioning. We examine whether the cognitive impact of such events is stronger if conditions very early in life were adverse, using Dutch longitudinal data of older persons. We...

When treatments may occur at different points in time, most evaluation methods assume – implicitly or explicitly – that all the information used by subjects about the occurrence of a future treatment is available to the researcher. This is often called the “no anticipation” assumption....

Nutritional conditions in utero and during infancy may causally affect health and mortality during childhood, adulthood, and at old ages. This paper investigates whether exposure to a nutritional shock in early life negatively affects survival at older ages, using individual data. Nutritional...
