The exogenous manipulation of choice architectures to achieve social ends ('social nudges') can raise problems of effectiveness and ethicality because it favors group outcomes over individual outcomes. One answer is to give individuals control over their nudge ('self-nudge'), but the trade-offs...

Like many common-pool resources, the Lake Victoria fisheries are characterized by poor compliance with production input regulations that are intended to reduce overexploitation. To explore the use of input subsidies to increase compliance, we determine the subsidy level required to induce demand...

We contribute to the literature on how program design affects program performance among vulnerable groups by studying the effects of varying the subsidy level and program procedures in an energy efficiency assistance program targeting low-income households in Germany. Eligible households...

An influential result in the literature on charitable giving is that matching subsidies dominate rebate subsidies in raising funds. We investigate whether this result extends to 'unit donation' schemes, a popular alternative form of soliciting donations. There, the donors' choices are about the...

We provide causal evidence on how date marking policies influence consumers' valuation of perishable food products through three consecutive research steps. In a preparatory in-store survey (n = 100), we identify perishable food items that can be experimentally manipulated to overcome core...

Charities frequently deviate from the standard donation scheme in which potential donors are asked how much money they are willing to give. Instead, they ask donors to choose how many units of a charitable good (e.g. meals, bed nets, or trees) to fund at a given unit price. In an online donation...

Anticipating "social risk", or risk caused by humans, affects decision-making differently from anticipating natural risk. Drawing upon a large sample of the US population (n=3,982), we show that the phenomenon generalizes to risk experience. Experiencing adverse outcomes caused by another human...

In a simplifying analytical framework with endogenous levels of actual and self-reported emissions, we consolidate the existing literature into three main hypotheses about the relative merits, for a resource-constrained regulator, of random (RAM) and competitive (CAM) audit mechanisms in the...

Can Attribution Science, a method for quantifying - ex post - humanity's contribution to adverse climatic events, induce pro-environmental behavioral change? We conduct a conceptual test of this question by studying, in an online experiment with 3,031 participants, whether backwards-looking...

Manipulating choice architectures to achieve social ends ('social nudges') raises problems of ethicality. Giving individuals control over their default choice ('selfnudges') is a possible remedy, but the trade-offs with efficiency are poorly understood. We examine under four different...
