Traditionally, giving in dictator games was assumed to signal preferences over others' payoffs. To date, several studies find that dictator game giving breaks down under conditions designed to increase dictators' anonymity or if an option to take money obscures the purpose of the task. Giving is...

This manual describes a z-Tree (Fischbacher, 2007) implementation of the paper-based Social Vaule Orientation (SVO) Slider Measure by Murphy et al. (2011). Using the paper-based version instead of the slider-based version (as implemented on the SVO-Website) avoids server-traffic related delays...

How malleable are people´s fairness ideals? Although fairness is an oft-invoked concept in allocation situations, it is still unclear whether and to what extent people´s allocations reflect their fairness ideals. We investigate in a laboratory experiment whether people´s fairness ideals vary...

Charitable donations are often made through intermediaries who can fund themselves from these same donations. Donors who purchase charitable output through an intermediary incur a principal-agent problem with unobservable prices. We compare charitable giving in an experiment with and without...

Do individuals prefer to compete fairly, or unfairly with an opponent? We study individuals who can choose how to compete for one ex-post nonzero payoff. They can either nudge themselves into a fair set of rules where they have the same information and actions as their opponent, or into unfair...

Relying on the specific example of ultimatum bargaining experiments this paper explores the possible role of empirical knowledge of behavioural norm(ative) facts" within the search for an inter-personal (W)RE - (Wide) Reflective Equilibrium on normative issues. Assuming that pro-social behaviour...

I conduct an experiment to assess whether majority voting on a nonbinding sharing norm affects subsequent behavior in a dictator game. In a baseline treatment, subjects play a one shot dictator game. In a voting treatment, subjects are first placed behind a 'veil of ignorance' and vote on the...

Bloggers devote significant time not only producing content for others to read, watch or listen to, but also paying attention to and engaging in interactions with other bloggers. We hope to throw light not only on the factors that gain bloggers significant readership and lively interactions with...

We conduct a natural field experiment on direct and indirect transfer mechanisms for small donations. Charitable contributions are significantly higher if made indirectly, i.e. if they are tied to the purchase of a good sold at a premium, than if they are made directly. Donations are...

Economists have been theorizing that other-regarding preferences influence decision making. Yet, what are the corresponding psychological mechanisms that inform these preferences in laboratory games? Empathy and Theory of Mind (ToM) are dispositions considered to be essential in social...
