Is there a way of matching donations that avoids crowding out? And, more generally, what is the best way to utilize a bigger lead gift for raising smaller contribu-tions in a fundraising campaign? To answer these questions, we present a novel matching method, some simple theoretical...

When asking for donations, charitable organizations often use suggestions concerning the amount of potential contributions. However, the evidence concerning the effects of such suggestions is scarce and inconsistent. Unlike the majority of existing studies concerned with small-money...

We analyse a stylized model of the world grain market characterized by a small oligopoly of traders with market power on both the supply and demand side. Crops are stochastic and exporting countries can impose export tariffs to protect domestic food prices. Our first result is that export...

In this note we shall discuss a concept that - despite its prominence in both Hume (1739) and Smith (1759), its obvious relevance for social behavior, and its not so infrequent use in colloquial language - has never gained a foothold in economic theory: the concept of empathy. Specifically, we...

We explore the stability of imitation in a 1,200-period experimental Cournot game where subjects do not know the payoff function but see the output quantities and payoffs of each oligopolist after every period. In line with theoretical predictions and previous experimental findings, our...

Is there a way of matching donations that avoids crowding out? We introduce a novel matching method where the matched amount is allocated to a different project, present some simple theoretical considerations that predict reduced crowding out or more crowding in (depending on the degree of...

Some companies engage in mass fundraising in addition to their core business. Via a corporate social responsibility (CSR) channel this may increase sales. However, ask avoidance, if present, could imply that fundraising activities may harm a company's core business. We examine how asking for...

We study a form of threshold matching in fundraising where donations above a certain threshold are topped up with a fixed amount. We show theoretically that threshold matching can induce crowding in if appropriately personalized. In a field experiment, we explore how thresholds should be chosen...

We study the causal relationship between moral values ("ought" statements) and factual beliefs ("is" statements) and show that, contrary to predictions of orthodox Bayesian models, values exert an influence on beliefs. This effect is mediated by prior political leanings and, thus, contributes to...
