Motivated by recent research on survey data, we test the influence of the political regime on social norms under controlled laboratory conditions. Comparing solidarity behavior revealed by East and West Germans in 1995 and 2009, we find that East Germans persistently show much less solidarity...

We investigate experimentally on eBay how sellers set prices in "Buy-It-Now" (BIN) auctions. We find that the eBay format leads to prices substantially below those expected in second-price auctions. Moreover, our results reveal that the information available on eBay about buyer experience and...

We study if and how social preferences extend to risky environments. By providing experimental evidence on different versions of dictator games with risky outcomes, we establish that social preferences of players who give in standard dictator games are best described by concerns for the...

We experimentally investigate the relevance of (asymmetric) outside options in ultimatum bargaining. Building on the generalized equity principle formulated by Selten (1978) we derive three di erent equity rules. These equity rules can explain 43% of all o ers. Our within-subject design allows...

This paper theoretically and experimentally studies decision-making in risky and social environments. We explore the interdependence of individual risk attitudes and inequality aversion as two decisive behavioral determinants in such contexts. Our model and the data demonstrate that individual...

This paper examines how people redistribute income when there is uncertainty about the role luck plays in determining opportunities and outcomes. We introduce a portable experimental method that generates exogenous variation in the probability that real workers' earnings are due to luck, while...

People overestimate the probability that others share their values or preferences. I introduce type projection equilibrium (TPE) to capture such projection in Bayesian games. TPE allows each player to believe his opponents share his type with intermediate probability \rho. After establishing...
