The structure of strategy-proof random social choice functions over product domains and lexicographically separable preferences

We characterize the class of dominant-strategy incentive-compatible (or strategy-proof) random social choice functions in the standard multi-dimensional voting model where voter preferences over the various dimensions (or components) are lexicographically separable. We show that these social choice functions (which we call generalized random dictatorships) are induced by probability distributions on voter sequences of length equal to the number of components. They induce a fixed probability distribution on the product set of voter peaks. The marginal probability distribution over every component is a random dictatorship. Our results generalize the classic random dictatorship result in Gibbard (1977) and the decomposability results for strategy-proof deterministic social choice functions for multi-dimensional models with separable preferences obtained in LeBreton and Sen (1999).     

政府间事权划分思路的比较与综合:基于中国现实的分析

政府间事权划分的传统思路是基于政府是公共产品供给主体这一基本认识,在既定的层级制政府架构下完成公共产品供给事权划分,具体采用了按公共产品种类、受益范围、部门单位隶属关系以及按事权构成要素进行划分的方法,但都难以完全做到在体现公平和效率原则的前提下明晰划分政府间事权.本文基于公共产品多中心供给这一基本认识,引入"功能覆盖型竞争性辖区"理论,把从公共产品的具体性质分析入手,通过设计、选择合适的供给主体来完成公共产品供给事权划分的思路称之为新思路.通过比较,可发现两种思路各有得失.因此,优化政府间事权划分,应实现两种思路的结合,以传统思路为主,新思路为辅.对遵循传统思路难以在层级制政府间明晰划分事权的公共产品,可具体问题具体分析,考虑选择合适的非政府供给主体,实现公共产品的多中心供给,这有助于解决政府间事权划分的棘手难题.     

A dynamic mechanism and surplus extraction under ambiguity

We study the question of auction design in an IPV setting characterized by ambiguity. We assume that the preferences of agents exhibit ambiguity aversion; in particular, they are represented by the epsilon-contamination model. We show that a simple variation of a discrete Dutch auction can extract almost all surplus. This contrasts with optimal auctions under IPV without ambiguity as well as with optimal static auctions with ambiguity—in all of these, types other than the lowest participating type obtain a positive surplus. An important point of departure is that the modified Dutch mechanism is dynamic rather than static, establishing that under ambiguity aversion—even when the setting is IPV in all other respects—a dynamic mechanism can have additional bite over its static counterparts. A further general insight is that the standard revelation principle does not automatically extend to environments not characterized by subjective expected utility.     

Drastic innovations and multiplicity of optimal licensing policies

Considering the licensing of a drastic cost-reducing innovation by an outside innovator in an n-firm Cournot oligopoly, we show that when the innovator uses combinations of fees and royalties, there are either n − 1 or n optimal licensing policies.     

Strengthening Stakeholder–Company Relationships Through Mutually Beneficial Corporate Social Responsibility Initiatives

Corporate social responsibility (CSR) continues to gain attention atop the corporate agenda and is by now an important component of the dialogue between companies and their stakeholders. Nevertheless, there is still little guidance as to how companies can implement CSR activity in order to maximize returns to CSR investment. Theorists have identified many company-favoring outcomes of CSR; yet there is a dearth of research on the psychological mechanisms that drive stakeholder responses to CSR activity. Borrowing from the literatures on means-end chains and relationship marketing, we propose a conceptual model that explains how CSR provides individual stakeholders with numerous benefits (functional, psychosocial, and values) and how the type and extent to which a stakeholder derives these benefits from CSR initiatives influences the quality of the relationship between the stakeholder and the company. The paper discusses the implications of these␣insights and highlights a number of areas for future research.     

A New Approach to Gravity Anomaly Separation: Differential Markov Random Field (DMRF)

In this paper the authors introduce a novel approach to stochastic image processing, denoted as Differential Markov Random Field (DMRF), which has been applied to gravity anomaly separation problems. The advantages of the method are that it introduces only little distortion into the shape of the original image and that it is not affected significantly by factors such as the overlap power spectra of regional and residual fields. Testing of the proposed meth using synthetic examples gave excellent results.
