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 resume the search for a collusive focal-point effect of price ceilings in laboratory markets. We argue that market conditions in previous studies were unfavorable for collusion which may have been responsible for not finding such a focal-point effect. Our design aims at maximizing the...

We investigate the effects of alternative open access regimes on market performance. In particular, by means of an economic laboratory experiment we compare the market outcomes under unregulated wholesale competition, under a price-fixing rule (where firms must maintain their wholesale price for...

We analyze the provision of a step-level public good in an experiment. Specifically, we investigate how the order of moves and the introduction of a second step-level affects public-good provision. We find that the sequential-move game improves public-good provision and payoffs. An additional...

With the use of a laboratory experiment, we show the effects of co-investments on coverage, competition and price collusion in regulated network industries. On the one hand, co-investments turn out not to be a significant driver of new infrastructure investments beyond the level achieved by...

Labels signaling sustainable product attributes are gaining importance, although uncertainty concerning the environmental, micro- and macroeconomic benefits of such labels persist. One of the questions still incom-pletely answered is whether Willingness To Pay (WTP) varies with a gradually...

Informed decisions are the cornerstone of a functioning democracy. The goal of this paper is twofold. First, to explore who is good at distinguishing between true and false, and, second, to learn something about mechanisms to debunk false news stories. In an experimental study, subjects were...
