Wage and Price Inflation in Poland in the Period of Transition: The Cointegration Analysis

The paper focuses on the long run relationships between wages, prices and labour productivity in the Polish economy by applying recent developments in the field of multivariate cointegration analysis. We followed modeling strategy which is suggested by Greenslade et al. (1999) and present all stages of the analysis which leads to the fully economically identified system of equations representing long run relationships. The investigation is based on the quarterly data from 1992.1 to 1999.2 which covers the period of transition of the Polish economy from the centrally planned system towards the market one. Basing on the empirical results we can argue that wages (costs) were one of the main forces driving inflation in Poland during that period. Also labor productivity proved to be stimulated by the increase of the real wages. On the other hand the hypothesis concerning the relationship between wages and unemployment was rejected by the data.     

公路建设中路线方案多属性决策方法的研究

路线方案的比选是公路建设项目前期的一项重要工作,直接影响着项目建设能否达到预期的目标以及项目投入运营中的使用效果,如行车的安全性、舒适性、快捷性等。进行路线方案比选时,要考虑路线的线形合理性、对周边地区环境影响,项目经济效益、施工难易等多种因素对影响。本文在分析路线方案比选复杂性的基础上,对多种决策方法进行对比,选择TOPSIS法作为路线方案的决策方法。算例的结果表明该方法应用的可行性和有效性。     

Optimal Patent Protection in a Two-Sector Economy

This article addresses the issue of optimal patent protection in an economy with a downstream and an upstream sector. The key insight is that higher patent protection in the downstream sector raises the incentives of agents to do R&D in that sector but discourages innovation in the upstream sector because of a market size effect. Hence, higher patent protection in the upstream sector accelerates growth whereas higher patent protection in the downstream sector slows it down. If some innovation is socially desirable, optimal patent protection is necessarily higher in the upstream than in the downstream sector.

反腐败之"高薪养廉"对策辨误

“高薪养廉”是很多人极力推崇的对策之一，无论是从理论上还是实践上看，“高薪养廉”都不适合中国国情，不能从根本上解决腐败问题。腐败问题的解决是一项系统工程。     

UNIT MANAGEMENT BUYOUTS, STOCKHOLDER WEALTH, AND SELLING FIRMS' CHARACTERISTICS

Previous research on unit management buyouts, UMBs, has shown that selling firms benefit from the selloff transaction. The current research demonstrates that when the selling firm has either poor liquidity or poor earnings, selling firm shareholders do not benefit as much. We hypothesize that the unit managers have knowledge about the selling firm's difficulties so they do not pay as large a premium for the assets. Since the unit managers technically are employed by the selling firm shareholders, their bargaining to achieve a better price is an agency cost. Finally, selloff frequency does not affect seller abnormal returns.
