Neyman and Scott (1948) define the incidental parameter problem. In panel data with T observations per individual and unobservable individual-specific effects, the maximum likelihood estimator of the common parameters is in general inconsistent. This paper develops the integrated moment...

This paper develops the minimal asymptotic distributions for estimators of panel data models with incidental parameters

This paper shows how the dynamic linear model with fixed regressors can be efficiently estimated. This dynamic model can be used to distinguish spurious correlation from state dependence and we show that the integrated likelihood estimator is adaptive for any asymptotics with T increasing where...

Job seekers can influence the arrival rate of job offers by the choice of search effort and the search methods they use. In this paper we empirically investigate the contribution of the use of different search methods on the outcome of search. Using unique data on the search behaviour of job...

We introduce two simple new variants of the Jackknife Instrumental Variables (JIVE) estimator for overidentified linear models and show that they are superior to the existing JIVE estimator, significantly improving on its small sample bias properties. We also compare our new estimators to...

This paper examines the empirical analysis of treatment effects on duration outcomes from data that contain instrumental variation. We focus on social experiments in which an intention to treat is randomized and compliance may be imperfect. We distinguish between cases where the treatment starts...

This paper analyzes the relationship between corporate taxation, firm age and debt. We adapt a standard model of capital structure choice under corporate taxation, focusing on the financing and investment decisions a firm is typically faced with. Our model suggests that the debt ratio is...

Die vorliegende Arbeit untersucht anhand von europäischen Firmendaten den Einfluss der Körperschaftsteuer auf die Unternehmensverschuldung. Dabei wird insbesondere auf Firmenheterogentität in Bezug auf Firmengröße und Gesellschaftsform fokussiert. Der verwendete Datensatz enthält...

This paper analyzes the relationship between capital structure, corporate taxation and firm age. We adapt a standard model of optimal capital structure choice under corporate taxation, focusing on the financing and investment decisions a young firm is typically faced with. Our model allows to...

Economists expect positive returns to investments in infrastructure. However a project with higher national returns might have less favourable effects on a regional level than the alternative. Therefore new infrastructure should also be assessed on a regional level, but econom(etr)ic evaluation...
