In games with strategic complementarities, public information about the state of the world has a larger impact on equilibrium actions than private information of the same precision, because the former is more informative about the likely behavior of others. This may lead to welfare-reducing...

Who does, and who should initiate costly certification by a third party under asymmetric quality information, the buyer or the seller? Our answer - the seller - follows from a nontrivial analysis revealing a clear intuition. Buyer-induced certification acts as an inspection device,...

Decisions to donate time or money for charitable purposes are typically seen as make-or-buy decisions, implying that there should be a clear distinction between individuals engaging in one of these two forms of giving and that this distinction should be somehow linked to opportunity costs. But...

Consider a two-product firm that decides on the quality of each product. Product quality is unknown to consumers. If the firm sells both products under the same brand name, consumers adjust their beliefs about quality subject to the performance of both products. We show that if the probability...

Unfavorable news are often delivered under the disguise of vagueness. But are people sufficiently naive to be fooled by such positive spin? We use a theoretical model and a laboratory experiment to study the strategic use of vagueness in a voluntary disclosure game. Consider a sender who aims at...

Before embarking on a project, a principal must often rely on an agent to learn about its profitability. We model this learning as a two-armed bandit problem and highlight the interaction between learning (experimentation) and production. We derive the optimal contract for both experimentation...

Recent literature has shown that lying behavior in the laboratory can well be explained by a combination of lying costs and reputation concerns. We extend the literature on lying behavior to strategic interactions. As reciprocal behavior is important in many interactions, we study a theoretical...

Credence goods markets are characterized by pronounced informational asymmetries between consumers and expert sellers. As a consequence, consumers are often exploited and market efficiency is threatened. However, in the digital age, it has become easy and cheap for consumers to self-diagnose...

We analyze optimal redistribution in the presence of labor market signaling where innate productive ability is not only unobserved by the government, but also by prospective employers. Signaling in both one and two dimensions is considered, where in the latter case firms have an informational...

Reporting private information is a key part of economic decision making. A recent literature has found that many people have a preference for honest reporting, contrary to usual economic assumptions. In this paper, we investigate whether preferences for honesty are malleable and what determines...
