We conduct a laboratory experiment with agents working on and principals benefiting from a real effort task in which the agents’ effort/performance can only be evaluated subjectively. Principals give subjective performance feedback to agents and agents have an opportunity to sanction...

We estimate structural models of guilt aversion to measure the population level of willingness to pay (WTP) to avoid feeling guilt by letting down another player. We compare estimates of WTP under the assumption that higher-order beliefs are in equilibrium (i.e. consistent with the choice...

Building on Battigalli and Dufwenberg (2009)'s framework of dynamic psychological games and the recent progress in the modeling of dynamic unawareness, we provide a general framework that allows for `unawareness' in the strategic interaction of players motivated by belief-dependent psychological...

What are the welfare effects of a policy that facilitates for insurance customers to privately and covertly learn about their accident risks? We endogenize the information structure in Stiglitz's classic monopoly insurance model. We first show that his results are robust: For a small information...

In a laboratory experiment designed to capture key aspects of the interaction between physicians and patients in a stylized way, we study the effects of medical insurance and competition in the guise of free choice of physician. Medical treatment is an example of a credence good: only the...

This paper addresses two issues. It documents the changes in the publication strategy of the members of the Department of Economics, University of Copenhagen over the last 50 years, away from a broad domestic audience to the international community of peers and scholars. From having been only...

Consumers have bounded perception and treat similar goods as homogeneous. The interaction between this bias and the structure of firms is studied in a vertically differentiated duopoly with market entry. With fixed costs of quality, natural monopoly and entry deterrence occurs at lower entry...

We derive the optimal hedging ratios for a portfolio of assets driven by a Cointegrated Vector Autoregressive model (CVAR) with general cointegration rank. Our hedge is optimal in the sense of minimum variance portfolio. We consider a model that allows for the hedges to be cointegrated with the...

We review recent asymptotic results on some robust methods for multiple regression. The regressors include stationary and non-stationary time series as well as polynomial terms. The methods include the Huber-skip M-estimator, 1-step Huber-skip M-estimators, in particular the Impulse Indicator...

I show that conventional estimators based on the consumption Euler equation, intensively used in studies of intertemporal consumption behavior, produce biased estimates of the effect of children on consumption if potentially binding credit constraints are ignored. As a more constructive...
