Can groups solve the problem of over-bidding in contests?

This study reports an experiment that examines whether groups can better comply with theoretical predictions than individuals in contests. Our experiment replicates previous findings that individual players significantly overbid relative to theoretical predictions, incurring substantial losses. There is high variance in individual bids and strong heterogeneity across individual...

The spatial range of public goods revealed through referendum voting

Billions of dollars are now spent annually in the United States and Europe for spatially delineated environmental services such as agricultural landscape management and river restoration programs, yet little is known about the spatial distribution of the benefits from these policies. This paper develops a framework for recovering information on this question from the spatial pattern...

The leaky pipeline in the Swiss university system : Identifying gender barriers in postgraduate education and networks using longitudinal data

Recent empirical studies provide evidence in favour of an equalization of male and female educational chances on the Master's level. This paper tackles the question whether gender inequalities develop after the completion of a Master's degree while starting an academic career. Using individual data from the Swiss Higher Education Information System we find that over the...

Risikoselektion in der sozialen Krankenversicherung der Schweiz: Überlebensstrategie in einem schlecht regulierten Markt

Kernstück des 2009 eingeführten Gesundheitsfonds ist die Einführung des morbiditätsorientierten Risikostrukturausgleichs. Die Einführung des so genannten Morbi-RSA hatte erhebliche Auswirkungen auf die Wettbewerbsposition der Krankenkassen und die finanziellen Anreize zur Weiterentwicklung von Versorgungsstrukturen. In diesem Band des Jahrbuch liegt der Schwerpunkt auf der...

An experimental study of auctions versus grandfathering to assign pollution permits

We experimentally study auctions versus grandfathering in the initial assignment of pollution permits that can be traded in a secondary spot market. Low and high emitters compete for permits in the auction, while permits are assigned for free under grandfathering. In theory, trading in the spot market should erase inefficiencies due to initial mis-allocations. In the experiment, high...

An experimental test of flexible combinatorial spectrum auction formats

This paper reports laboratory experiments that evaluate the performance of a flexible packagebidding format developed by the FCC, in comparison with other combinatorial formats. In general, the interest of policy makers in combinatorial auctions is justified by the laboratory data; when value complementarities are present, package bidding yields improved performance. We find clear...

Hierarchical package bidding: a paper & pencil combinatorial auction

We introduce a new combinatorial auction format based on a simple, transparent pricing mechanism tailored for the hierarchical package structure proposed by Rothkopf, Peke~c, and Harstad (1998) to avoid computational complexity. This combination provides the feedback necessary for bidders in multi-round auctions to discern winning bidding strategies for subsequent rounds and to...

An experimental analysis of auctioning emissions allowances under a loose cap

The direct sale of emissions allowances by auction is an emerging characteristic of cap-and-trade programs. This study is motivated by the observation that all of the major implementations of cap-andtrade regulations for the control of air pollution have started with a generous allocation of allowances relative to recent emissions history, a situation we refer to as a “loose cap.”...

An adverse selection model of optimal unemployment insurance

We ask whether offering a menu of unemployment insurance contracts is welfare-improving in a heterogeneous population. We adopt a repeated moral hazard framework as in Shavell and Weiss(1979), supplemented by unobserved heterogeneity about agents’ job opportunities. Our main theoretical contribution is a quasi-recursive formulation of our adverse selection problem, including a...

The effects of increasing financial incentives for firms to promote employment of disabled workers

I study the effect of an increase in financial incentives for firms to hire disabled workers in the context of an employment quota. My results suggest that this increase had a positive impact on firms' demand for disabled workers.

Distinguishing trust from risk: an anatomy of the investment game

The role of trust in promoting economic activity and societal development has received considerable academic attention by social scientists. A popular way to measure trust at the individual level is the so-called “investment game” (Berg, Dickhaut, and McCabe, 1995). It has been widely noted, however, that risk attitudes can also affect decisions in this game, and thus in principle...

The Swiss franc exchange rate and deviations from uncovered interest parity: global vs domestic factors

We examine the role of global and country-specific factors for the Swiss franc exchange rate in the period 1990–2009. Simple asset pricing theory would predict that exchange rates reflect relative movements in national discount factors and that systematic departures from uncovered interest parity can only be explained by international differences in the exposure to the common (global...

The economic consequences of foreigner rules in national sports leagues

Profitable and balanced domestic league sports are among the central prerequisites for attracting the right to host a mega-event like the soccer world cup as well as for the overall economic success of such events. This paper pro-vides a contest model of a professional team sports league and analyzes the impact of a restriction on foreign players. It shows that a league with binding...

Equity fund ownership and the cross-regional diversification of household risk

We explore the link between portfolio home bias and consumption risk sharing among Italian regions using household-level information on consumption, income and portfolio holdings. Since equity funds are typically diversified at the national or international level, we use data on equity fund ownership to proxy for regional home bias. Cross-regional patterns of equity fund ownership...
