We study equilibrium reporting behavior in cheating games when agents have a fixed cost of lying and image concerns not to be perceived as a liar. We show that equilibria naturally arise in which agents with low costs of lying randomize among a set of the highest potential reports. Such equilibria induce a distribution of reports in line with observed experimental patterns. We also find that higher image concerns lead to an increase in the range of reported lies, while the effect of the fixed cost of lying is the opposite. (JEL C72, D82, Z13)

In a theoretical and an experimental analysis of a sender-receiver game we investigate whether sanctions for lying induce more truthtelling. The novel aspect in our model is that senders may not only choose between truth-telling and (explicit) lying, but may also engage in evasive lying by credibly pretending not to know. While we find that sanctions promote truth-telling when senders cannot engage in evasive lying, this is no longer true when evasive lying is possible. Then, explicit lying is largely substituted by evasive lying, which completely eliminates the otherwise positive effect of sanctions on the rate of truthtelling. As outlined in our model, the necessary prerequisite for such an 'erosion' effect is that evasive lying is perceived as sufficiently less psychologically costly than direct lying. Our results clearly demonstrate the limitations of sanctioning lying to counteract the exploitation of informational asymmetries and may explain the empirical evidence from the finance industry that sanctions for financial misconduct eventually appear to be not very efficient.

We study strategic communication between a customer and an advisor who is privately informed about the best suitable choice for the customer, but whose preferences are misaligned with the customer's preferences. The advisor sends a message to the customer who, in turn, can secure herself from bad advice by acquiring costly information on her own. We find that making the customer's information acquisition less costly, e.g., through consumer protection regulation or digital information aggregation and dissemination, leads to less prosocial behavior of the advisor. This can be explained by a model of shared guilt, which predicts a shift in causal attribution of guilt from the advisor to the customer if the latter could have avoided her ex post disappointment.
