This paper outlines why program evaluation should follow well-respected scientific standards and why it should be performed by independent researchers.

Recently, building on the highly polarizing Stiglitz report, a growing literature suggests that statistical offices and applied researchers explore other aspects of human welfare apart from material well-being, such as job security, crime, health, environmental factors and subjective...

Compulsory military service typically drafts young men when they are at the height of their learning ability. Thus, it can be expected to depress the demand for higher education since skill atrophy and the delayed entry into the civilian labor market reduce the returns to human-capital...

We test whether financial incentives have an effect on weight reduction in a randomized controlled trial involving 700 obese persons assigned to three experimental groups. While two treatment groups obtain €150 and €300, respectively, for achieving an individually assigned target weight...

Volunteering plays a prominent role in the charitable provision of goods and services, yet we know relatively little about why individuals spend time and money to the charity. Assuming that volunteering is a consumption good, we analyze the determinants of individuals' charitable cash donations...

We identify the causal effect of compulsory military service on conscripts' subsequent labor-market outcomes by exploiting the regression-discontinuity design of the military draft in Germany during the 1950s. Unbiased estimates of the effect of military service on lifetime earnings, wages, and...

This paper investigates whether and to what extent demographic change has an impact on human capital accumulation. The effect of the relative cohort size on educational attainment of young adults in Germany is analyzed utilizing data from the German Socio-Economic Panel for West-German...

Taking a European cross-country perspective, this paper addresses the most important issues in the nexus of population ageing and labor markets. We start from a descriptive overview of the demographic change currently shaping European societies. The subsequent section intensively discusses the...

Using the location of baroque opera houses as a natural experiment, Falck et al. (2011) claim to document a positive causal effect of the supply of cultural goods on today's regional distribution of talents. This paper raises serious doubts on the validity of the identification strategy...

Arguably, one of the most important developments in the field of applied economics during the last decades has been the emergence of systematic policy evaluation, with its distinct focus on the establishment of causality. By contrast to the natural sciences, the objects of our scientific...
