The matching method for treatment evaluation does not balance selective unobserved differences between treated and non-treated. We derive a simple correction term if there is an instrument that shifts the treatment probability to zero in specific cases. Policies with eligibility restrictions,...

Matching methods for treatment evaluation based on a conditional independence assumption do not balance selective unobserved differences between treated and nontreated. We derive a simple correction term if there is an instrument that shifts the treatment probability to zero in specific cases....

Causal effects of a policy change on hazard rates of a duration outcome variable are not identified from a comparison of spells before and after the policy change, if there is unobserved heterogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that...

We consider the impact of tax credits and income support programs on female education choice, employment,hours and human capital accumulation over the life-cycle. We analyze both the short run incentive effects and the longer run implications of such programs. By allowing for risk aversion and...

This Paper exploits area-based piloting and age-related eligibility rules to identify treatment effects of a labour market program – the New Deal for Young People in the UK. A central focus is on substitution/displacement effects and on equilibrium wage effects. The programme includes...

We consider the impact of tax credits and income support programs on female education choice, employment, hours and human capital accumulation over the life-cycle. We analyze both the short run incentive effects and the longer run implications of such programs. By allowing for risk aversion and...

This Paper examines changes in the distribution of wages using bounds to allow for the impact of non-random selection into work. We show that bounds constructed without any economic or statistical assumptions can be informative. Since employment rates in the UK are often low they are not...

Are all Japanese youth ready for the structural reforms proposed as a supply-side policy of Abenomics? To answer this question, we assess how well Japanese youth have coped with the labor market's long-term structural changes, induced primarily by deepening interdependence with emerging...

We consider the problem of choosing two bandwidths simultaneously for estimating the difference of two functions at given points. When the asymptotic approximation of the mean squared error (AMSE) criterion is used, we show that minimisation problem is not well-defined when the sign of the...
