Gold,liquidity and secured loans in a multistage economy

A multistage economy with durables with finite and with unbounded lives is considered. The importance of the existence of both asset and rental markets is considered. It is shown that without rental markets efficiency may not be achieved and a stationary state that might exist with rental markets need not exist. The meaning of the existence of a 100% backed loan is considered. The roles of gold and land as stores of value and money are considered.Research supported in part by ONR Grant N00014-86-K-0220 and by NSF Grant No. SES-8812051.     

岩溶山地土地整理模式研究

西南岩溶山地是典型的脆弱生态环境,与经济发达地区相比,有其自身的土地资源特点、生态特点和社会特点。文章以此为基础,提出岩溶山地土地整理的原则、思路,认为岩溶山地的土地整理应从高标准基本农田建设、阶梯式还林退耕和辐射式生态重建、实行土地双轨制、直接对农户投资着手等,提出不同空间尺度如县市、乡镇、村组、农户土地整理的具体模式。非耕地资源开发是岩溶山地土地整理的重点。     

增长失衡与政府责任——基于社会性支出角度的分析

当前中国的发展出现了以国富与民生关系失衡为本质特征的增长失衡。本文从教育、医疗和社会保障等与民生有关的政府责任切入,指出当前中国与民生状况直接相关的政府社会性支出的不足,是导致增长失衡的重要原因。为此,政府应在提供教育、医疗和社会保障等方面承担起基本的责任,加快财政支出结构转型,增加社会性支出的比重,改善民生状况,纠正增长失衡;并通过社会性支出的增加,促进人力资本积累,推动增长路径的转变,实现经济长期健康发展。

On the theory of cost sharing

This paper investigates efficiency and equitability issues given a cost sharing method in an economy with a public commodity. We study the concept of a -cost share equilibrium and examine the set of all equilibrium allocations. Finally, we devise a mechanism to implement -cost share equilibria as strong equilibria of an associated non-cooperative game.This paper was written while Shlomo Weber was visiting the University of Bonn.

Assessing the impact of patent infringement on new product sales

In order to assess the impact of patent infringement on the growth of a new product, a model is developed through the intervention model development processes of Box-Jenkins and Box-Tiao. Physical interpretations of model parameters and determination of associated damages suggest that the model can provide a sound basis for analyzing patent infringement disputes.
