The European Union Statistics on Income and Living Conditions (EU-SILC) is a rotational panel provided by Eurostat that covers important variables over all EU Member States. Unfortunately, Eurostat provides separate data sets which do not cover all waves. Furthermore, information on monthly...

Today 2.6 billion people in developing countries rely on biomass as primary cooking fuel, with profound negative implications for their well-being. Improved biomass cooking stoves are alleged to counteract these adverse effects. This paper evaluates take-up and impacts of low-cost improved...

Today more than 2.7 billion people rely on biomass as their primary cooking fuel, with profound implications for the environment and people’s well-being. Wood provision is often time-consuming and the emitted smoke has severe health effects – both burdens that afflict women in particular....

In the public promotion of R&D cluster and network formation, the following situation typically arises: An initial network structure has developed over a long time span and policy measures affect the structure of links between the actors. This new network structure influences the effectiveness...

The classical Heckman (1976, 1979) selection correction estimator (heckit) is misspecified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specification problem, a full information maximum likelihood estimator and a...

In a randomized controlled trial involving 700 obese persons assigned to three experimental groups, we test whether financial incentives have heterogeneous effects on weight reduction. While two treatment groups obtain EUR 150 and EUR 300, respectively, for achieving an individually-assigned...

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 Euro150 and Euro300, respectively, for achieving an individually assigned target weight...

We complement the empirical evidence on the sustainability of weight loss achieved through cash rewards and, for the first time, rigorously examine the potential of cash rewards to prevent weight cycling. In a three period randomized controlled trial, about 700 obese persons were first assigned...

We document an increase in the scoring probability from penalties in soccer, which separates the time period before 1974 significantly from that after 1976: the scoring probability increased by 11%.We explain this finding by arguing that the institution of penalty-shooting before 1974 is best...
