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...

This note attempts to reconcile a range of primary methods for dealing with price asymmetry, such as the approaches proposed by Tweeten and Quance (1969), Wolffram (1971) and Houk(1977). Using Wolffram’s stylized example, we first illustrate that the notion of asymmetry can be captured in a...

The allure of an environmentally benign, abundant, and cost-effective energy source has led an increasing number of industrialized countries to back public financing of renewable energies. Germany's experience with renewable energy promotion is often cited as a model to be replicated elsewhere,...

We provide evidence that motorists respond to short-run fluctuations in fuel prices at the gas pump and not on the road. Employing variants of censored panel regression to control for unobserved heterogeneity and censoring of the dependent variable, we find that the fuel price has a large and...

This article revisits an analysis by Frondel, Ritter and Schmidt (2008) of Germany’s Renewable Energy Act, which legislates a system of feed-in tariff s to promote the use of renewable energies. As in the original article, we argue that Germany’s support scheme subsidizes renewable energy...
