Commitment in R&D Tournaments via Strategic Delegation to Overoptimistic Managers

This paper shows that it is profitable for a firm to hire an overoptimistic manager to commit to a certain investment strategy in an R&D tournament situation. In the unique symmetric equilibrium, all firms delegate to overoptimistic managers, where the optimal degree of overoptimism depends on the riskiness of the tournament. In these situations a manager’s type may serve as a substitute for delegation via contracts. By delegating to overoptimistic managers, firms can escape the rat race nature of R&D tournaments.Strategic Delegation; Overoptimism; Tournaments

Information, Coordination, and the Industrialization of Countries

The industrialization process of a country is often plagued by a failure to coordinate investment decisions. Using the Global Games approach we can solve this coordination problem and eliminate the problem of multiple equilibria. We show how appropriate information provision enhances efficiency. We discuss extensions of the model and argue that subsidies may be a property of a signalling equilibrium to overcome credibility problems in information provision. In addition we point out possible problems with overreaction to public information. Furthermore, we suggest a new focus for development policy

Determinants and Effects of Reserve Prices in Hattrick Auctions

We use a unique hand collected data set of 6,258 auctions from the online football manager game Hattrick to study determinants and effects of reserve prices. We find that chosen reserve prices exhibit both very sophisticated and suboptimal behavior by the sellers. On the one hand, reserve prices are adjusted remarkably nuanced to the resulting sales price pattern. However, reserve prices are too clustered at zero and at multiples of e 50,000 as to be consistent with fully rational behavior. We recover the value distribution and simulate the loss in expected revenue from suboptimal reserve prices. Finally, we find evidence for the sunk cost fallacy as there is a substantial positive effect on the reserve price when the player has been acquired previously

Free Riding in the Lab and in the Field

We run a public good experiment in the field and in the lab with (partly) the same subjects. The field experiment is a true natural field experiment as subjects do not know that they are exposed to an experimental variation. We can show that subjects' behavior in the classic lab public good experiment correlates with their behavior in the structurally comparable public good treatment in the field but not with behavior in any of two control treatments we ran in the field. This effect is also economically significant. We conclude that a) the classic lab public good experiment captures important aspects of structurally equivalent real life situations and b) that behavior in lab and field at least in our setting is driven by the same underlying forces

A Model of Strategic Delegation in Contests between Groups

We analyze a contest between two groups where group members have differing valuations for the contested rent. Generically the pivotal group member with the median valuation of the rent will not act himself but will want to send a group member that has preferences different to her own into the contest. The delegation can be either to more or less 'radical' group members. The direction of delegation depends on the order of moves and the relative 'aggressiveness' of the group medians. We show that almost certainly very asymmetric equilibria arise, even if the median group members value the rent (almost) equally. Delegation can lead to a social improvement in terms of resources spent in the contest.strategic delegation, contests, rent seeking, political economy, arms races, distributional conflict

Free-Riding in the Lab and in the Field

To investigate the external validity of laboratory results, we combine a public good experiment with three treatments in a field experiment. One treatment offers the opportunity to free-ride, the other two are placebo treatments. We compare results within subjects. In the free-riding treatment, subjects who contribute little in the lab are less productive. This effect is quantitatively as important as the effect of ability. The correlation between lab and field disappears in the two placebo treatments. We conclude that we can use lab experiments to learn about behavior in situations that share the game form but not necessarily the frame.field and lab experiments, external validity, public goods, team production

Reserve Price Formation in Online Auctions

We use a unique hand collected data set of 6 258 auctions from the online football manager game Hattrick to study micro-patterns of reserve price formation. We find that chosen reserve prices exhibit both, very sophisticated and “irrational” behavior by the sellers. Reserve prices pick up the “birthday effect” in sales prices, documented in Englmaier and Schmöller (2008) and are adjusted remarkably nuanced to the resulting sales price pattern. Moreover, reserve prices are too clustered (around multiples of €50 000) as to be consistent with fully rational behavior. Furthermore, we find evidence for entitlement effects and the sunk cost fallacy as there is a huge positive effect on the reserve price when the player has been acquired previously.auctions, reserve price, bounded rationality, heuristics, entitlement effect

Contracts and Inequity Aversion

Using the concept of Inequity Aversion we derive in a Moral Hazard setting several results which differ from conventional contract theory. Our three key insights are: First, inequity aversion plays a crucial role in the design of optimal contracts. Second, there is a strong tendency towards linear sharing rules, giving a simple and plausible rationale for the prevalence of these schemes in the real world. Third, the Sufficient Statistics result no longer holds as optimal contracts may be ”too” complete. Along with these key insights we derive a couple of further results.contract theory, linear contracts, incentives, sufficient statistics result, inequity aversion, fairness
