Free-riding is a major problem in peer to networks. One of the ways resolve this by using reputation management system. Each node provides resources nodes with higher reputation, as he himself gains proportion receiver’s reputation. So, free-riding becomes non-optimal strategy there no resulting gain, and hence available over time. An efficient accurate trust estimation method system needed for...

We present a new mechanism for encouraging risk taking within organizations that relies on the provision of decision insurance to managers. Since insurance increases the likelihood of free riding, we also introduce a technique that mitigates this moral hazard by automatically identifying the social network around the manager and using it as a monitoring group. We show that three possible regime...

The use of business insurance has been traditionally studied in a single-firm setting. But in reality preventing operational accidents involves the (unobservable) efforts of multiple firms. We show that, in a multi-firm setting, insurance can be used strategically as a commitment mechanism to prevent excessive free-riding by other firms. In the presence of wealth imbalances, contracts alone lea...

We consider popular file-sharing systems such as Kazaa from a game theoretic perspective. Such systems are inherently vulnerable to free-riding, that is, to users who download files but do not contribute in return. The result is that these systems do not maximize the number of files exchanged; in the parlance of mechanism design, these mechanisms do not implement the desired social choice funct...

We investigate the implications of collective and individual producer responsibility (CPR and IPR, respectively) models of product take-back laws for e-waste on manufacturers’ design for product recovery (DfR) choices and profits, and on consumer surplus in the presence of product competition. We show that IPR offers superior DfR incentives as compared to CPR, and provides a level competitive g...

This paper develops a non-Schumpeterian endogenous growth model of R&D in which the firm’s free-riding behavior, reinforced by a lack of appropriability in its industry, constitutes a major source of growth in the economy. While models analyzing the interaction between either imitation and innovation or spillovers and innovation have already appeared in the literature, we show how imitation via...

Recent research efforts have shown that the popular BitTorrent protocol does not strictly enforce fairness and allows free-riding, mainly via optimistic unchokes. This paper proposes a BitTorrent-like protocol, that encourages peers of similar upload bandwidth to be buddies— peers collaborating for mutual benefit. Buddy peers mostly satisfy their download needs through their buddies and perform...

ion—Solving free riding and selecting a reliable service provider in P2P networks has been separately investigated in last few years. Using trust has shown to be one of the best ways of solving these problems. But using this approach to simultaneously deal with both problems makes it impossible for newcomers to join the network and the expansion of network is prevented. In this paper we used th...
