This paper analyses the impact of a change in Australia's immigration policy, introduced on 1st July 1999, on migrants' probability of being over-/under-educated or correctly matched. The policy change consists of stricter entry requirements about age, language ability, education, and work...

We study whether Australian employers recognise immigrants' education acquired abroad, and if so how. Using data from the Longitudinal Surveys of Immigrants in Australia, we apply interval regression to model migrant hourly earnings. We find substantially higher returns from human capital...

We study smoking persistence in ten countries using data from the European Community Household Panel. Such persistence may be due to true state dependence but may also reflect individual unobserved heterogeneity. We distinguish between the two by using semi-parametric dynamic panel data methods...

We investigate whether people enrolled into voluntary health insurance (VHI) substitute public consumption with private (opt out) or just enlarge their private consumption, without reducing reliance upon public provisions (top up). We study the case of Italy, where a mixed insurance system is in...

Shared-frailty survival models specify that systematic unobserved determinants of duration outcomes are identical within groups of individuals. We consider random-effects likelihood-based statistical inference if the duration data are subject to left-truncation. Such inference with...

This paper analyses the impact of a change in Australia's immigration policy, introduced in the mid-1990s, on migrants' probability of becoming entrepreneurs. The policy change consists of stricter entry requirements and restrictions to welfare entitlements. The results indicate that those who...

We estimate a double hurdle (DH) model of the Hungarian wage distribution assuming censoring at the minimum wage and wage under-reporting (i.e. compensation consisting of the minimum wage, subject to taxation, and an unreported cash supplement). We estimate the probability of under-reporting for...

We estimate the effect of a shortening of unemployment benefit entitlements on unemployment duration. Previous studies on the same or related problems have not taken into account that the competing risks duration model is not identified and we shed first light on the question whether the non...

The cause of immigrant education mismatch in the host country labour market might not necessarily be discrimination or imperfect transferability of human capital, as argued in previous studies. Immigrants who have gained professional experience in the home country in jobs below their education...

Bivariate duration data frequently arise in economics, biostatistics and other areas. In "bivariate frailty models", dependence between the frailties (i.e., unobserved determinants) induces dependence between the durations. Using notions of quadrant dependence, we study restrictions that this...
