We analyze delegation of a set of decisions over time by an informed principal to a potentially biased agent. Each period the principal observes a state of the world and sends a “cheap-talk” message to the agent, who is privately informed about her bias. We focus on principal-optimal...

In this paper, we consider a dynamic signaling model of an R&D market in which a researcher can choose either a safe project (exploitation) or a risky project (exploration) at each instance. We argue that there are substantial efficiency gains from rewarding minor innovations above their social...

Interactions between players with private information and opposed interests are often prone to bad advice and inefficient outcomes, e.g. markets for financial or health care services. In a deception game we investigate experimentally which factors could improve advice quality. Besides advisor...

This paper examines the interplay between career concerns and market structure. Ability and effort are complements: effort increases the probability that a skilled agent achieves a one-time breakthrough. Wages are based on assessed ability and on expected output. Effort levels at different times...

We analyze the costs and benefits of using social image to foster virtuous behavior. A Principal seeks to motivate reputation-conscious agents to supply a public good. Each agent chooses how much to contribute based on his own mix of public-spiritedness, private signal about the value of the...

Two experimental treatments are used to study the effects of auction risk across five mechanisms. The first canonical, baseline treatment features only strategic risk and replicates the standard results that overbidding relative to the risk neutral Nash equilibrium is prevalent in all common...

Utilizing data for comparable BSc graduates in economics who have studied in different universities that had set the same entry standards, we compare job seekers' employment prospects when they search by themselves for jobs by submitting CVs to the same firms. The outcomes suggest that graduates...

This paper analyzes a mechanism through which a supplier of unknown quality can overcome its asymmetric information problem by selling via a reputable downstream rm. The supplier’s adverse-selection problem can be solved if the downstream rm has established a reputation for delivering high...

This paper studies a repeated-game model in which firms can build a reputation for rewarding innovative employees. In any Pareto efficient equilibrium, low-value innovations get developed in established firms, while high-value innovations get developed in startups. The threshold level can be...

We develop and estimate a general equilibrium model to quantitatively assess the effects and welfare implications of central bank transparency. Monetary policy can deviate from active inflation stabilization and agents conduct Bayesian learning about the nature of these deviations. Under...

Die vorliegende Dissertation umfasst drei Arbeiten zu unterschiedlichen Aspekten der Monitoring-Funktion von Kreditratings im Sekundärmarkt für Kreditrisiken. Basierend auf einem umfassenden Datensatz über den Ratingverlauf aller von Standard & Poor's, Moody's und Fitch zwischen 1985 und 2012...

Interactions between players with private information and opposed interests are often prone to bad advice and inefficient outcomes, e.g. markets for financial or health care services. In a deception game we investigate experimentally which factors could improve advice quality. Besides advisor...

In credence goods markets, experts have better information about the appropriate quality of treatment than their customers. As experts provide both diagnosis and treatment, this leaves scope for fraud. We experimentally investigate how intensity of price competition and the level of customer...

It is known that there are uncoupled learning heuristics leading to Nash equilibrium in all finite games. Why should players use such learning heuristics and where could they come from? We show that there is no uncoupled learning heuristic leading to Nash equilibrium in all finite games that a...

We experimentally examine the effects of price competition in markets for expe-rience goods where sellers can build up reputations for quality. We compare price competition to monopolistic markets and markets where prices are exogenously fixed (somewhere between the endogenous oligopoly and...

We study reputational herding in financial markets in a laboratory experiment. In the spirit of Dasgupta and Prat (2008), career concerns are introduced in a sequential asset market, where wages for investors are set by subjects in the role of employers. Employers can observe investment...

The link between Corporate Social Responsibility (CSR) activities and financial performance of firms has been intensively examined and debated in academics and politics, but the connection to innovation has so far lacked research attention. This paper investigates whether CSR is complementary to...

Die Unternehmensreputation hat sich im Zeitalter der Globalisierung und Digitalisierung zu einem der wichtigsten Erfolgsfaktoren entwickelt. Die Wissenschaft begleitet diese Entwicklung durch intensive theoretische und empirische Forschungsarbeiten. Trotz unzureichender Datensätze besteht...
