Social norms involve observation by others and external sanctions for violations,while moral norms involve introspection and internal sanctions. We develop a simple model ofindividual preferences that incorporates moral and social norms. We then examine dictatorchoices, where we create a shared understanding by providing advice from peers with nofinancial payoff at stake. We vary whether advice is given, as well as whether choices are madepublic. This design allows us to explicitly separate the effects of moral and social norms. Wefind that choices are in fact affected by a combination of observability and the sharedunderstanding.

Credit default swaps (CDS) played an important role in the financial crisis of 2008 leading to calls for regulation. Here, we seek to understand the impact of a CDS regulation that restricts the possibility to hold naked CDS. We use a controlled laboratory experiment analyzing CDS pricing in a bond market subject to default risk. Our results show that the regulation achieves the goal of increasing the use of CDS for hedging purposes while reducing the use of CDS for speculation. This success does not come at the expense of lower initial public offering (IPO) prices for the bonds or worse pricing of bonds or CDS in the secondary market.

An important feature of bond markets is the relationship between the initial public offering (IPO) price and the probability that the issuer defaults. On the one hand, the default probability affects the IPO price; on the other hand, the IPO price affects the default probability. It is a priori unclear whether agents can competitively price such assets. Our paper is the first to explore this question. To do so, we use laboratory experiments. We develop two flexible bond market models that are easily implemented in the laboratory. We find that subjects learn to price the bonds well after only a few repetitions.
