Fixed Exchange Rates and Disinflation in Emerging Markets: How Large Is the Effect?

We examine developing countries which have institutional quality ratings for the effects of exchange rate rigidity on inflation. The level of institutional development exerts no effect on the impact of currency regimes. However, the interaction of institutional quality and exchange rates has, in the most plausible specifications, a negative impact on inflation. This suggests that fixed exchange rates exert at most a contingent effect on inflation, and indicates that countries in Eastern Europe and Latin America contemplating currency pegs would be better off improving institutional quality prior to adopting the euro or dollar and expecting a large subsequent disinflationary effect.

中间选民理论在农民工市民化政策制定中的运用——基武汉市436位农民工的实证研究

The Median Voter Theory is an important theory in the neo-political economics. It can be applied to solve the collective choice paradox and analyze the policy making for the citizenization of peasant workers. Adopting the method of factor analysis, this paper makes an empirical study on peasant workers’ preference for citizenization. We find that there is a paradox of future residence preference and self-identification in peasant workers. On this basis, peasant workers are divided into 5 subgroups, and it is found that the median undecided peasant workers are the median voters. Based on the analysis of the median undecided peasant worker’s complaints and appeals, it is proposed that the country should strengthen the vocational training system, establish a social security system, expand the agricultural reform and promote educational reform to facilitate the citizenization of peasant workers. __________ Translated from Guanli Shijie 맜理世界 (Management World), 2007, (4): 40–67

Towards a complete real-time electricity market design

The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices, if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission. The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.

中国改革开放以后地方税制度的改革

改革开放以前，中国实行高度集中的经济、财政、税收管理体制，税收的归属随着财政、税收管理体制的变化频繁调整，没有形成完整的地方税制度。改革开放以后，中国开始解决经济、财政、税收管理体制过于集中的问题，逐步调整中央与地方的财政、税收分配关系，并从1994年起将上述分配关系初步纳入分税制的轨道，建立了由中央税、地方税、中央与地方共享税构成的分税制财政管理体制，比较完整的地方税制度由此初步形成。     

A generalization of Condorcet’s Jury Theorem to weighted voting games with many small voters

We extend Condorcet’s Jury Theorem (Essai sur l’application de l’analyse à la probabilité des décisions rendues à la pluralité des voix. De l’imprimerie royale, 1785) to weighted voting games with voters of two kinds: a fixed (possibly empty) set of ‘major’ voters with fixed weights, and an ever-increasing number of ‘minor’ voters, whose total weight is also fixed, but where each individual’s weight becomes negligible. As our main result, we obtain the limiting probability that the jury will arrive at the correct decision as a function of the competence of the few major players. As in Condorcet’s result the quota q = 1/2 is found to play a prominent role. I wish to thank Maurice Koster, Moshé Machover, Guillermo Owen and two anonymous referees for helpful comments.
