Market clearing and derivative pricing

Summary. We develop a method of assigning unique prices to derivative securities, including options, in the continuous-time finance model developed in Raimondo (2001). In contrast with the martingale method of valuing options, which cannot distinguish among infinitely many possible option pricing processes for a given underlying securities price process when markets are dynamically incomplete, our option prices are uniquely determined in equilibrium in closed form as a function of the underlying economic data.Received: 14 April 2003, Revised: 7 January 2004, JEL Classification Numbers: G13, D52.This paper is dedicated to Birgit Grodal, whose strength and character we greatly admire.

Extensive-form games and strategic complementarities

I prove the subgame-perfect equivalent of the basic result for Nash equilibria in normal-form games of strategic complements: the set of subgame-perfect equilibria is a nonempty, complete lattice—in particular, subgame-perfect Nash equilibria exist. For this purpose I introduce a device that allows the study of the set of subgame-perfect equilibria as the set of fixed points of a correspondence. My results are limited because extensive-form games of strategic complementarities turn out—surprisingly—to be a very restrictive class of games.     

现代物流与经济增长的VAR模型分析

本文在建立VAR模型的基础上，运用脉冲响应函数和预测方差分解来刻画现代物流发展与经济增长关系的相关性。研究结果表明，我国的现代物流发展与经济增长之间存在着较强的正向相关性。因此，在当前条件下，加速推进现代物流发展是持续促进经济增长的重要路径选择。     

基于博弈理念构建和谐税收制度的基本思路

本文阐述了和谐税收制度对建设和谐社会的重要性,指出和谐的税收制度应是一种纳什均衡的制度.运用博弈理念,从税种结构博弈均衡、税收负担博弈均衡、税收征管博弈均衡及稽查监督博弈均衡四个方面给出构建和谐税收制度的基本思路.     

制度与经济增长

以诺斯为代表的新制度经济学把制度因素引入到经济增长理论之中,并认为制度是经济增长的决定因素,从而打破了新古典经济增长理论制度既定的假设条件,使经济增长理论更趋成熟和完善。但制度对经济增长起主要作用是有条件的,即在制度不均衡的条件下,制度对经济增长起主要作用,而在制度均衡的条件下,对经济增长起主要作用的是技术而不是制度。     

国有产权改制中政府与投资人的均衡策略研究

本文简要回顾了国有产权改制的研究背景与意义，利用动态博弈的思想构建了政策与投资者博弈的动态均衡模型，并对双方博弈均衡应采取的策略进行了分析，进而提出推进国有产权改制的相关政策建议。     

基于社会责任的企业环境信息披露博弈分析

企业的生产经营活动对人们赖以生存的环境产生着重大影响，所以企业应承担向社会公众披露有关环境信息的责任。目前,企业的环境信息披露情况不容乐观．为了促使经济健康发展．本文通过建立模型来分析企业与相关入之间的博弈关系，试图达到一种经济学上的“帕累托最优”状态。     

关税减让政策对我国进口的影响

中国加入WTO后,关税减让协议的逐步实行对我国进口贸易产生了极大影响.研究结果表明,关税与我国进口贸易额之间存在着高度的负相关关系,在影响我国进口效应的诸多因素中.关税起到了主要作用,但并非唯一因素.而关税减让在影响我国进口商品结构方面的作用不大.可见,在优化我国进口商品结构方面还需要其他政策措施的辅助与调整.     

Congestion effects in a public-good economy

This paper considers a public-good economy with congestion, where participants jointly produce a public good from input of a private good. This economic model gives rise to a transferable-utility game, the profit game, that depends on consumer preferences and a congestion parameter. The simplicity of the game allows the maximum level of congestion that guarantees the nonemptiness of the core of the economy to be determined. It is known that the sustainability of the Lindahl equilibrium in the core of the economy depends on the distribution of profits. In this paper two distributions of profits are compared: the Lindahl solution and the marginal-contribution solution. The latter is more often in the core than the Lindahl solution which in turn Lorenz-dominates the marginal-contribution solution.
