We develop a simple semiparametric framework for combining censored and uncensored samples so that the resulting estimators are consistent, asymptotically normal, and use all information optimally. No nonparametric smoothing is required to implement our estimators. To illustrate our results in...

I investigate the effects of population ageing on immigration policies. Voters' attitude towards immigrants depends on how the net gains from immigration are divided up in the society by the fiscal policy. In the theoretical literature this aspect is treated as exogenous to the political process...
