Hotelling’s famous Principle of Minimum Differentiation suggests that two firms engaging in spatial competition will decide to locate at the same place. Interpreting spatial competition as modeling product differentiation, firms will thus offer products that are not differentiated and equally...

We combine two extensions of the differentiated duopoly model of Dixit (1979), namely Caminal and Vives (1996) and Brander and Spencer (2015a,b), to analyze the effect of consumer learning on firms' incentives to differentiate their products in models of Cournot and Bertrand competition....

The seminal studies by Allcott and Mullainathan (2010), Allcott (2011), and Allcott and Rogers (2014) suggest that social comparison-based home energy reports (HER) are a cost-effective non-price intervention to stimulate energy conservation. The present paper demonstrates the context-dependency...

This paper evaluates an intervention that randomized information letters about energy efficient investments and behaviors among 120,000 customers of two utilities in Germany. We find that conservation effects differ considerably between both utilities, ranging from a precisely estimated zero...

The use of well-designed improved cookstoves (ICS) in regions devoid of modern energy yields high private and social returns, mostly related to considerable woodfuel savings. Take-up rates are nonetheless often very low when people have to pay costcovering prices. This paper presents main...

Energy labels have been introduced in many countries to increase consumers' attention to energy use in purchase decisions of durables. In a discrete-choice experiment among about 5,000 households, we implement randomized information treatments to explore how energy labels influence purchasing...

Germany has implemented a range of measures to mitigate climate change. The implementation of such measures results in the imposition of financial burdens and restrictions on residents. Consequently, individual attitudes toward the fairness and effectiveness of such measures are a critical...

This data report describes the first wave of the RWI Climate-Mobility Panel, a recurring household survey that aims in particular to investigate individual mobility behavior and preferences with regard to mobility-related policies. It further includes information on attitudes towards...

This paper proposes a model for a certification market with an imperfect testing technology. Such a technology only assures that whenever two products are tested the higher quality product is more likely to pass than the lower quality one. When only one certifier with such testing technology is...
