This paper contains a review of the early history of program evaluation research at the US Department of Labor. Some broad lessons for successful evaluation research are summarized.

Politikentscheidungen gestalten die Wohlfahrt von Nationen, aber ihre Praxis erfolgt komplexen Regeln. Evidenzbasierte Politikberatung durch Wissenschaftler will forschungsbasierten harten Fakten und Restriktionen Gewicht geben. Der Beitrag diskutiert Herausforderungen und Erfolgsbedingungen...

While policy measures affect the welfare of nations, the practice of policy advice is determined by complex rules. Evidence-based scientific policy advice gives weight to hard empirical facts and restrictions. The lecture discusses challenges and conditions for success and provides suggestions...

We build on Rosenzweig and Wolpin (2000) and Keane (2010) and show that in order to fulfill the Instrumental variable (IV) identifying moment condition, a policy must be designed so that compliers and non-compliers either have the same average error term, or have an error term ratio equal to...

We consider an artificial population of forward looking heterogeneous agents making decisions between schooling, employment, employment with training and household production, according to a behavioral model calibrated to a large set of stylized facts. Some of these agents are subject to policy...

This paper examines the role of other-regarding and time preferences for cooperation in the field. We study the preferences of fishermen whose main, and often only, source of income stems from using a common pool resource (CPR). The exploitation of a CPR involves a negative interpersonal and...

We investigate if, and under which conditions, the distinction between dictatorial and incentive-based policy interventions affects the capacity of Instrument Variable (IV) methods to estimate the relevant treatment effect parameter of an outcome equation. The analysis is set in a non-trivial...

Scientific rhetoric can have a profound impact on the perception of research; it can also drive and direct further research efforts. What determines whether results are discussed in a neutral or a judgmental way? How precise and convincing must results be so that authors call for significant...

Der Beitrag berichtet über persönliche Erfahrungen aus der Politikberatung in der Frühphase der Arbeitsmarktreformen zu Beginn der letzten Dekade vor dem Hintergrund der wissenschaftlichen Neuorientierung der Wirtschaftsforschungsinstitute aufgrund von Auflagen des Wissenschaftsrates. Der Rat...

We show that within a life-cycle skill accumulation model, IV identification of the return to schooling parameter is either achieved at any point in the life-cycle where the level of skills accumulated beyond school completion for compliers is exactly equal to the post-schooling skill level of...
