We consider a simple contest game with draws where with some probability none of the contestants is selected as winner. If such an outcome occurs, then the contest is repeated in the next period unless either one of the contestants wins the prize or until a final last period is reached. Allowing...

In subtractive manufacturing, differences in machinability among batches of the same material can be observed. Ignoring these deviations can potentially reduce product quality and increase manufacturing costs. To consider the influence of the material batch in process optimization models, the...

Even though global supply chains are (usually unintentionally) tied to slave labor, research and practice have largely ignored the issue. This is expected to change as civil society activism and new legislation increase the risk of litigation and reputational damage to supply chain partners. To...

Conflict parties are frequently involved into more than one conflict at a given time. In this paper the interrelated structure of conflictive relations is modeled as a conflict network where opponents are embedded in a local structure of bilateral conflicts. Conflict parties invest in specific...

This paper provides existence and characterization of the optimal contest success function under the condition that the objective of the contest designer is total effort maximization among n heterogeneous players. Heterogeneity of players makes active participation of a player in equilibrium...

This paper analyzes the incentive effects of affirmative action in competitive environments modeled as contest games. Competition is between heterogeneous players where heterogeneity might be due to past discrimination. Two policy options are analyzed that tackle the underlying asymmetry: Either...

This paper provides existence and characterization of the optimal contest success function under the condition that the objective of the contest designer is total effort maximization among n heterogeneous players. Heterogeneity of players makes active participation of a player in equilibrium...

We allow a contest organizer to bias a contest in a discriminatory way; i.e., she can favor specific contestants by designing the contest rule in order to maximize total equilibrium effort (resp. revenue). The two predominant contest regimes are considered, all-pay auctions and lottery contests....

Our study analyzes the consequences of workers' participation in the wage setting process on effort exertion. The experimental design is based on a modified giftexchange game where the degree of workers' involvement in the wage setting process is systematically varied among the workers. The...

We characterize revenue maximizing head starts for all-pay auctions and lottery contests with many heterogeneous players. We show that under optimal head starts all-pay auctions revenue-dominate lottery contests for any degree of heterogeneity among players. Moreover, all-pay auctions with...
