Matching has become a popular approach to estimate average treatment effects. It is based on the conditional independence or unconfoundedness assumption. Checking the sensitivity of the estimated results with respect to deviations from this identifying assumption has become an increasingly important topic in the applied evaluation literature. If there are unobserved variables which affect assignment ...

We evaluate three policy reforms targeted at older unemployed people: (i) an hourly wage subsidy, (ii) an in-work credit, and (iii) a subsidy of social security contributions on low wages. The work incentive, labour supply and welfare effects of these hypothetical reforms are analysed on the basis of a detailed micro-simulation model for Germany which includes a structural household labour supply model. ...

Germany is known to have one of the lowest fertility rates among Western European countries and also relatively low employment rates of mothers with young children. Although these trends have been observed during the last decades, the German public has only recently begun discussing these issues. In order to reverse these trends, the German government recently passed a reform of the parental leave ...

We present a method for taking advantage of labour market transitions to identify effects of financial incentives on employment decisions. The framework we use is very flexible and by imposing few theoretical assumptions allows extending the modelled sample relative to struc-tural models. We take advantage of this flexibility to include disabled people in the model and to analyse behaviour of disabled ...

We analyze the effects of three alternative proposals to reform the taxation of families relative to the current German system of joint taxation of couples and child allowances: a French-type family splitting and two full family splitting proposals. The empirical analysis of the effects of these proposals on the income distribution and on work incentives is based on a behavioral micro-simulation model ...

In diesem Beitrag wird auf der Basis von Paneldaten für die westdeutschen Bundesländer untersucht, ob und in welchem Maße der demographische Wandel sowie die unterschiedlichen politischen Parteienkonstellationen die Hochschulausgaben auf Länderebene beeinflussen. Wir finden empirische Evidenz für die Hypothese, dass die Hochschulausgaben negativ von der Bevölkerungsalterung abhängen, allerdings hängt ...

The influence of risk aversion on the decision to become self-employed is a much discussed topic in the entrepreneurial literature. Conventional wisdom asserts that the role model of an entrepreneur requires to make risky decisions in uncertain environments and hence that more risk-averse individuals are less likely to become an entrepreneur. Empirical tests of this assumption are scarce however, mainly ...

In this paper we investigate how the expulsion of a player influences the out-come of a football match. Common sense implies a negative impact for the affected team. However, an old football myth suggests that such an expulsion might also be beneficial since it increases the team spirit as well as the efforts of the affected team. We make use of a unique dataset containing all games played in a World ...

Entrepreneurial activity is often regarded as an engine for economic growth and job creation. Through tax policy, governments possess a potential lever to influence the decisions of economic agents to start and close small businesses. In Germany, the top marginal income tax rates were reduced exclusively for entrepreneurs in 1994 and 1999/2000. These tax reforms provided two naturally defined control ...

In this paper we suggest a Stata routine for multinomial logit models with unobserved heterogeneity using maximum simulated likelihood based on Halton sequences. The purpose of this paper is twofold: First, we provide a description of the technical implementation of the estimation routine and discuss its properties. Further, we compare our estimation routine to the Stata program gllamm which solves ...
