Credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies, such as under- and overtreatment or market break-down. We study in a large experiment with 936 participants the determinants for efficiency in credence goods...

We focus on the role that the transmission of information between a multilateral (the IMF) and a country has for the optimal design of conditional reforms. Our model predicts that when agency problems are especially severe, and/or IMF information is valuable, a centralized control is indeed...

Credence goods markets with their asymmetric information between buyers and sellers are prone to large inefficiencies. In theory, poorly informed consumers can protect themselves from maltreatment through sellers by asking for second opinions from other sellers. Yet, empirical evidence whether...

We analyze a competitive labor market in which workers signal their productivities through education à la Spence (1973), and firms have the option of auditing to learn workers' productivities. Audits are costly and non–contractible. We characterize the trade–offs between signaling by...

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 study experimentally the effect of bargaining power in two sequential mechanisms that offer the possibility to trade at a fixed price before an auction. In the "Buy-It-Now" format, the seller has the bargaining power and offers a price prior to the auction; whereas in the "Sell-It-Now"...

Credence goods are characterized by informational asymmetries between sellers and consumers that invite fraudulent behavior by sellers. This paper presents the results of a natural field experiment on taxi rides in Athens, Greece, set up to measure different types of fraud and to examine the...

This paper explores the role of information transmission in explaining donors' choice between project aid and budget support. Budget support increases the involvement of recipient governments in the decision-making process and can thus be an example of a “delegation-scheme.” Conversely,...
