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.     

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.
