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...

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...

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.

Economic pluralism proposes that economists and social planners should consider alternative theories to establish a range of policy actions. Neoclassical, Feminist and Marxian theories evaluate well-grounded causes of wage discrimination. Racist attitudes, uncertainties regarding minority...

We measure a specific form of other-regarding behavior, costly cooperation with an anonymous other, among 645 subjects at a trucker training program in the Midwestern US. Using subjects' second-mover strategy in a sequential form of the Prisoners' Dilemma, we categorize subjects as: Free Rider,...

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 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...
