    Choosing and Sharing

    Choosing a project for which benefits accrue to all involved agents but brings major costs or additional benefits to only one agent is often problematic. Siting a nationwide nuclear waste disposal or hosting a major sporting event are examples of such a problem: costs or benefits are tied to the identity of the host of the project. Our goals are twofold: to choose the efficient site (the host with the lowest cost or the highest localized surplus) and to share the cost, or surplus, in a predetermined way so as to achieve redistributive goals. We propose a simple mechanism to implement both objectives. The unique subgame-perfect Nash equilibrium of our mechanism coincides with truthtelling, is efficient, budget-balanced and immune to coalitional deviations.

    Implementing a project, like a nationwide nuclear waste disposal, which benefits all involved agents but brings major costs only to the host is often problematic. In practice, revelation issues and redistributional concerns are significant obstacles to achieving stable agreements. We address these issues by proposing the first mechanism to implement the efficient site (the host with the lowest cost) and share the exact cost while retaining total control over realized transfers. Our mechanism is simple and in the vein of the well-known Divide and Choose procedure. The unique Nash equilibrium outcome of our mechanism coincides with truthtelling, is budget-balanced, individually rational and immune to coalitional deviations. More generally, our mechanism can also handle the symmetric case of positive local externalities (e.g., Olympic Games) and even more complex situations where the usefulness of the project---regardless of its location---is not unanimous.Public goods; local externalities; NIMBY; implementation; mechanism design; VCG mechanisms

    Prize Sharing in Collective Contests

    The characteristics of endogenously determined sharing rules and the group-size paradox are studied in a model of group contest with the following features: (i) The prize has mixed private-public good characteristics. (ii) Groups can differ in marginal cost of effort and their membership size. (iii) In each group the members decide how much effort to put without observing the sharing rules of the other groups. It is shown that endogenous determination of group sharing rules completely eliminates the group-size paradox, i.e. a larger group always attains a higher winning probability than a smaller group, unless the prize is purely private. In addition, an interesting pattern of equilibrium group sharing rules is revealed: the group attaining the lower winning probability is the one choosing the rule giving higher incentives to the members.collective contest, mixed public-good prize, endogenous sharing rules, the group-size paradox

    Competitive Equilibria With Limited Enforcement

    This study demonstrates how constrained efficient allocations can arise endogenously as equilibria in an economy with a limited ability to enforce contracts and with private agents behaving competitively, taking a set of taxes as given. The taxes in this economy limit risk-sharing and arise in an equilibrium of a dynamic game between governments of sovereign nations. The equilibrium allocations depend on governments choosing to tax both the repayment of international debt and the income from capital investment in their countries.

    A Study of the Changing Process of Knowledge-Sharing Habits

    In this research, we explore the impacts encountered by teachers with respect to sharing their teaching material and knowledge as a college implements the “Faculty-Student Knowledge Sharing Platform (FSKSP).” In addition, we report the experience and progress they acquire when choosing to change their traditional, habitual teaching and sharing modes. The case study focuses on a college of technology well-renowned among universities in Taiwan for its total and integral electronization of teaching. The study shows that sharing knowledge with students through the FSKSP is very different in nature from the long-established verbal knowledge sharing in classroom lectures. In choosing to use the FSKSP and making changes to the interaction between faculty and students, the teachers go through the stages of: Protection of professional dignity and expertise, panic with regard to whether or not to make changes, compromise with respect to the trends in information technology, and hesitation about whether to march forward or turn back. The research findings serve as a good reference for college administrators as they advocate the introduction of information technology to construct the FSKSP
