This paper develops a nonparametric methodology for treatment evaluation with multiple outcome periods under treatment endogeneity and missing outcomes. We use instrumental variables, pre-treatment characteristics, and short-term (or intermediate) outcomes to identify the average treatment...

Whenever the economic model of behaviour is to be applied, the utility function has – at least somewhat – to be specified. Buchanan generally prefers to apply a rather narrow version. However, he acknowledges that it is hardly possible to explain actual behaviour of individuals with such a...

Using data from the German Socio-Economic Panel, this paper analyses the effects of spending part of adolescents’ leisure time on playing music or doing sports, or both. We find that while playing music fosters educational outcomes compared to doing sports, particularly so for girls and...

If labour market policies aimed at people with disabilities are effective, we should observe no significant difference in labour market outcomes between disable and non-disable individuals. This paper examines the impact of disability status on labour market outcomes using matching methods...

Venture capitalists not only finance but also advise and thereby add value to young innovative firms. The prospects of venture capital backed firms thus depend on joint efforts of entrepreneurs and informed venture capitalists, and are subject to double moral hazard. In financing a portfolio of...

Easley / Kiefer / O'Hara / Paperman (1996) (EKOP) have proposed an empirical methodology that allows to estimate the probability of informed trading and that has subsequently been used to address a wide range of issues in market microstructure. The data needed for estimation is the number of...

Non-random item nonreponse makes identification if parameters problematic. Such nonresponse can occur with respect to both dependent and conditioning variables. A method often used to reduce nonresponse is that of adding unfolding brackets as follow up to open-ended questions. With these,...

In German literature, particularly in poetry, an amazing wealth of illustrations for economic contract theory can be found. Signaling, screening, incentive contracts, the winner's curse, and even the prisoner's dilemma within a team are treated by different writers. The respective examples are...

In the absence of financing frictions, profit taxes reduce investment by their effect on the user cost of capital. With finance constraints due to moral hazard, investment becomes sensitive to cash-flow and own equity of firms. The impact of taxes changes fundamentally. Taxes reduce investment...

Child-care subsidies are meant to facilitate work for mothers with small children. The paper demonstrates that the predominant current subsidy scheme in Switzerland, which ties the subsidies to realized income (but not to potential income), creates strongly negative work incentives especially...
