|About the Data|
|Data Description:||Online and pen/paper survey data gathered from 2533 individuals; sample reduced to 2068 after missing values were removed. Sample of 2068 individuals used for descriptive results and sample of 1063 individuals used for estimation results. The descriptive sample was composed of 81% males and 19% females and found that 48.6% of individuals did not participate in P2P networks, 28.82% were free-riders, and 22.58% contributed to P2P networks. The authors do not specify which industry the P2P file-sharing relates to, and they do not specify a funder for the research.|

In this paper, we examine the determinants of sharing behaviour by envisaging two types of behaviour, namely contribution against free riding. In doing so, we evaluate the theoretical predictions about reciprocity and altruism in the presence of non-rival goods and anonymity. We use a probit model and primary data from a survey that collects information about P2P sharing behaviour of more than 2000 individuals. Our econometric results suggest that the motivations for contributing are poorly determined by rational self-interested behaviour. We then envisage policy implications in terms of copyright enforcement and business.
Main Results of the Study
The main results reported by this study:
- The value of P2P networks is marginally significant. However, the marginal effect is negative and very low.
- The quest for cultural diversity makes individuals more likely to be a contributor than a free-rider in P2P networks.
- The perception of legal and technical risks associated with sharing behaviour has no significant effect on contribution.
- A moderate level of education is associated with a lower likelihood of being a contributor in P2P.
- Age, income and occupation do not have a significant impact on behaviour in P2P networks.
- Higher internet experience has significant positive impact on contribution behaviour.
- Findings suggest that contribution behaviour is not well explained by an utilitarian approach.
- Contribution behaviour can be motivated by social influence, and these practices are embedded in a social context.
- Further research can explore the mechanisms by which this social influence explains the behaviour of contributors over P2P networks.
Policy Implications as Stated By Author
Policy implications reported in the study:
- A major way to fight against P2P networks is to reduce their absolute utility by increasing the costs associated with contribution in order to dry up the supply of contents on P2P networks. However, the findings suggest copyright enforcement (in particular, increased sanctions, legal suits against individual copiers) has no impact on contribution behaviour. This might explain the failure of current enforcement strategies.
- The findings cast some doubts on the efficiency of ‘réponse graduée,’ or the use of warnings and cease and desist letters: at best, this new form of copyright enforcement could eliminate the current P2P technology used to share contents. Any new sharing technology that would replace current P2P technology might be fuelled by the ‘supply’ of content contributors.
- Another strategy is to decrease the relative utility of P2P networks by increasing the quality of services and diversity of contents available in the legal markets. Content industries should try to build innovative business models to compete efficiently with P2P content-sharing or even to extract the value from these sharing communities.
- Copyright law could stimulate innovation by implementing compulsory licences in order to facilitate the acquisition of copyrights and increase the size of catalogue supplied to consumers in legal markets.
