We study the effect of repeated opportunities to behave pro-socially on aggregate pro-social behavior in two laboratory experiments and in field data on charitable giving. In the first experiment we show that two consecutive pro-social decisions (implemented as donations to a charity) lead to...

Carbon taxes are a prominent policy instrument for decreasing the consumption of CO2-intensive goods in order to reduce the negative external effects involved in the production or consumption of such goods. A tax leads to higher consumer prices, which typically lowers consumption. However, in...

Policy makers increasingly use choice defaults to promote `good' causes by influencing socially relevant decisions in desirable ways, e.g., to increase pro-environmental choices or pro-social behavior in general. Such default nudges are remarkably successful when judged by their effects on the...

This paper reports evidence from a field experiment investigating households' electricity saving behavior. We motivated households' efforts to save electricity via pro-environmental incentives that did not affect people's monetary utility but targeted their environmental preferences. The results...

Environmental activities, for instance actions against climate change, are an important part of Corporate Social Responsibility (CSR). This paper studies how a employer's environmental CSR activities affect the pro-environmental behavior of its employees. To do so, we conducted a large-scale...

Small and Medium-sized Enterprises (SMEs) make up the largest share of companies in most economies. They are major users of resources and cause a large share of environmental pollution, which makes them relevant targets for public policy programs aiming to increase their sustainability. We study...

Small and medium-sized enterprises (SMEs) often lack the knowledge and the resources necessary to implement best practices in environmental management. This makes them a relevant target for public policy measures trying to enhance sustainable decision making in the economy. This paper reports...

Choice defaults are an increasingly popular public policy tool. Yet there is little knowledge of the distributional consequences of such nudges for different groups in society. We report results from an elicitation study in the residential electricity market in Switzerland in which we contrast...

Many countries have liberalized their residential electricity markets or are considering to do so. Liberalization provides consumers with more freedom of choice but also leads to higher choice complexity as consumers face a much larger number of different electricity contracts to choose from. We...
