This paper explores equivalent formulations of the polarization ordering first proposed by Foster and Wolfson. Motivated by the class of polarization indices proposed by Foster and Wolfson, we have developed a class of generalized Foster-Wolfson indices. In addition, a new class of polarization indices satisfying a set of desirable axioms is also derived. .hk!. We thank two anonymous referees for very helpful suggestions and comments.

A recent body of literature with the paradigm of market preserving federalism at its core contends that China is a de facto federalist state. With the autonomy and tax rights of local governments entrenched in the reform era, local governments have allegedly become decentralized engines of growth. Scrutinizing the underlying premises of the above paradigm, this article arrives at a picture of China's local governments as less autonomous and the system of vertical bureaucratic control as more potent than that painted by the above paradigm. Emerging from our findings is an alternative interpretation of China's central–local fiscal relations that may help us understand such recent phenomena as the proliferation of arbitrary charges.

This article develops a generic framework to explain the environment for public–private partnership (PPP) development in transitional economies. The framework stands on a tripod that includes the market, the operating environment, and the government, each containing several factors that support aspects of PPPs. The authors apply the framework to analyze the results of a multicountry survey in an effort to identify key factors that facilitate PPP development in transition countries. The identified factors are market potential, institutional guarantee, government credibility, financial accessibility, government capacity, consolidated management, and corruption control. The framework and identified factors may serve as effective tools to diagnose and monitor PPP development in a broader array of countries. The framework is applied in analyzing data from four transitional economies and several advanced economies. The efficacy of the framework is further justified by its explanatory power of PPPs’ practicality and is largely confirmed by results from a sensitivity test.
