A Survey of Experimental Research on Contests, All-Pay Auctions and Tournaments

Many economic, political and social environments can be described as contests in which agents exert costly efforts while competing over the distribution of a scarce resource. These environments have been studied using Tullock contests, all-pay auctions and rankorder tournaments. This survey provides a review of experimental research on these three canonical contests. First, we review studies investigating the basic structure of contests, including the contest success function, number of players and prizes, spillovers and externalities, heterogeneity, and incomplete information. Second, we discuss dynamic contests and multi-battle contests. Then we review research on sabotage, feedback, bias, collusion, alliances, and contests between groups, as well as real-effort and field experiments. Finally, we discuss applications of contests to the study of legal systems, political competition, war, conflict avoidance, sales, and charities, and suggest directions for future research.

“Individuals voting choice and cooperation in repeated social dilemma games”

In this paper we explore the relationship between the individual’s preference for cooperation and the establishment of cooperative norms. Our aim is to provide an experimental test of the evolutionary hypothesis (see Carpenter, 2004, Fehr and Gachter 2002; Gintis 2000; Boyd, Bowles, Gintis and Richerson 2003; Bowles and Gintis 2004), according to which individuals are prepared to punish defectors in experimental social dilemma games because they want to enforce a social (“altruistic”) norm which may conduce to increasing their future payoffs, as in the case of sanctions against free riding behaviour. According to this line of research , the high levels of cooperation we observe in our societies can, therefore, be strictly related to the establishment of social norms which are able to enforce and maintain cooperation in the long run. We study the results of two experiments in which the individuals decided both whether to participate in a common project and the institutional rule according to which the profits of the project had to be shared among each of the participants in the group

Recent Development in the Theory of Innovation and Technical Change

This paper surveys the contribution that recent developments in theory and empirical research in technical change have made to the understanding of the problem. In particular, the paper surveys the contributions in the microeconomics of technical change. It is argued that this area has been strongly influenced by J. Schumpeter and his theory of innovation
