We use the theory of abstract convexity to study adverse-selection principal-agent problems and two-sided matching problems, departing from much of the literature by not requiring quasilinear utility. We formulate and characterize a basic underlying implementation duality. We show how this...

In contest models with symmetric valuations, equilibrium payoffs are positive shares of the value of the prize. In contrast to a bargaining situation, these shares sum to less than one because a share of the value is lost due to rent-dissipation. We ask: can every such division into payoff...

We present a bottom-up electricity market model for Switzerland called Swissmod. It includes a detailed electricity network and hydropower representation. Swissmod captures the features and restrictions of run-of-river, yearly storage and pumped-storage power plants and combines this with a...

Shill bidding is a fraudulent in-auction strategy where a seller participates as a bidder in his own auctions. This is the first paper on shill bidding that is based on a data set which includes personal details. Along with bidding histories, I can prove that on the investigated platform 0.3% of...

This paper extends the firm heterogeneity model of Melitz (2003) by introducing a new concept of endogenous investments in process R&D. The novelty is that if a firm invests more in R&D its expected innovation return hazard rate stochastically dominates the return of less R&D investments. Due to...

We study markets in which agents first make investments and are then matched into potentially productive partnerships. Equilibrium investments and the equilibrium matching will be efficient if agents can simultaneously negotiate investments and matches, but we focus on markets in which agents...

Natural gas plays an important role in the future development of electricity markets as it is the least emission intensive fossil generation option while additionally providing the needed flexibility in plant operation to deal with intermittent renewable generation. As both the electricity and...

This paper investigates the average effects of (firm-provided) workplace health promotion measures in form of the analysis of sickness absenteeism and health circles/courses on labour market out­comes of the firms' employees. Exploiting linked employer-employee panel data that consist of rich...

Am 1. Juni 2008 befürwortete das Stimmvolk der Stadt Luzern ein neues Reglement über die Videoüberwachung im öffentlichen Raum. Infolgedessen wurden Mitte Dezember 2008 sechs Überwachungskameras am Bahnhofplatz Luzern installiert und in Betrieb genommen. Der vorliegende Evaluationsbericht...
