We consider a modi¯ed pure public good game characterized by a pre-play negotiation stage, onwhich pairs of players can form binding cooperation commitments. As the introduced mecha-nism only supports pairwise rather than more inclusive commitments, it does not implement thee±cient outcome. We...

Ordinarily, the process of decision making by a committee through voting is mod-elled by a monotonic game the range of whose characteristic function is restricted tof0; 1g: The decision rule that governs the collective action of a voting body induces ahierarchy in the set of players in terms of...

The Shapley value of a cooperative transferable utility game distributes the dividendof each coalition in the game equally among its members. Given exogenous weightsfor all players, the corresponding weighted Shapley value distributes the dividendsproportionally to their weights. In this...

We study a particular class of cost sharing games – "data games" – covering situations wheresome players own data which are useful for a project pursued by the set of all players. Theproblem is to set up compensations between players. Data games are subadditive butgenerally not concave, and...

This paper examines the puzzlingly high unexploited momentum returns from a new perspective.We analyze characteristics of momentum traders in a sample of 692 fund managers. Wefind that momentum traders are “defined” by their short-term horizon, by a behavioural viewon the market and by a...

When workers send applications to vacancies they create a network. Frictions arise becauseworkers typically do not know where other workers apply to and firms do not know whichcandidates other firms consider. The first coordination friction affects network formation, whilethe second coordination...

This paper analyses the effects of innovation networks on product and pro-cess innovation and sales growth of high technology SMEs. Innovation net-works are positively related to both product and process innovation, i.e. know-ledge creation. One exception is the negative effect of innovation...

This paper experimentally investigates the interdependence between market competition and endogenously emerging inter-firm collaboration. We restrict attention to arrangements resulting from bilateral collaboration agreements that typically characterize real world applications in which the...

Many social networks have the following properties: (i) a short average distancebetween any two individuals; (ii) a high clustering coe±cient; (iii) segregation pat-terns; the presence of (iv) brokers and (v) hubs. (i) and (ii) de¯ne a small worldnetwork. This paper develops a strategic...

This paper analyses the process of knowledge growth in a branch of medical science. Our study of scientific advances in glaucoma research is organized in two parts. In the first we present a qualitative overview of the problem sequences that have characterized 150 years of medical research in...
