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.     

Price-wage dynamics in a transition economy: The case of Poland

In this paper we analyse the wage-price relationship of an economy in transition characterized by important structural changes. It is known (see Perron, 1989) that structural breaks in stationary time series can induce apparent unit roots. The stationarity analysis of the series employed in the present model is conducted jointly with the assumption that the breakpoint location is unknown. We follow a testing procedure recently proposed by Zivot and Andrews (1992). Cointegration analysis of wages and prices in the presence of structural breaks finds empirical evidence in favour of two cointegrating vectors involving prices and wages. Our analysis focuses on the different structural behaviour of the price-wage dynamic relationship in the short and long term; we also demonstrate the relative importance of import prices as a source of wage-price fluctuations.     

Pay determination in small firms in the UK: the case of the response to the National Minimum Wage

Pay determination in small firms is widely expected to follow the dictates of the market. Research on 81 firms in three competitive sectors finds, instead, loosely defined and variable pay structures. This variability is explained in terms of the interplay between labour and product markets, firms’ own choices, and ‘shocks’ such as the National Minimum Wage. This analysis thus contributes to developing institutional theories of labour markets and pay systems.     

Wage determination and sex discrimination in Japan

In spite of a significant contribution by female workers to the post-war economic expansion of Japan, the average female wage remains no more than half the average male wage. In his study, Nanshi Matsuura found that workers' wages are mostly determined by non-job-performance-related factors, some of which are based on discriminatory social elements.     

Wage determination in urban Russia: Underpayment and the gender differential

A stochastic frontier wage equation is employed to examine labor-market efficiency and estimate workers’ potential wages in Russia after a decade of economic reforms using a nationally representative household survey. Dynamic monopsony underpayment, defined as the differences between the highest wage a worker with given characteristics could earn and the worker's actual wage, is a significant factor lowering real wages. The estimated degree of underpayment differs significantly depending on gender and substantially exceeds the estimates for Western economies. Workers’ potential wages are elastic with respect to the local cost of living. Women's mean potential wage is only 58% of men's.     

Wage determination in the union and nonunion sectors.

This study contains estimates of wage equations for white male union and nonunion employees. The authors find that nonunion wages are generally more responsive than union wages to individuals' education and experience and to regional price-level variation. Despite those differences, however, estimates of union-nonunion wage differentials based on these separate equations do not differ greatly from a differential obtained from a union dummy variable in an equation based on combined union and nonunion observations. Union-nonunion differentials vary widely across occupational groups and are generally larger in the lower skilled and more highly unionized occupations. The results for manufacturing, for which additional industry data are available, indicate a negative impact of high concentration ratios on the wages of all workers and a greater impact of establishment size on nonunion than on union wages. Data were drawn from the May 1973 Current Population Survey.

The impact of changes in second pension pillars on public finances in Central and Eastern Europe: The case of Poland

This paper studies the impact of the recent weakening of Poland's fully funded defined contribution second pension pillar on (i) the long-term sustainability (the deficit and implicit debt) of the full pension system and (ii) the implications for pension benefits (gross replacement rates). Simulation results, based on a stylised version of the Polish pension system, show that, in the baseline scenario, the weakening of the second pillar would permanently lower future pension system debt, chiefly as a result of a cut in replacement rates. But using a combination of pessimistic assumptions including strong population ageing, low real wage growth and an indexation of existing pension benefits on nominal wage growth rather than inflation coupled with bringing in tax expenditures related to the third voluntary pension pillar and an increase in the share of minimum pensioners leads to higher pension system deficits and eventually more public debt at a very long horizon. The simulation results also suggest that if Poland had not transformed its pay-as-you-go first pension pillar into a defined contribution from a defined benefit system, the weakening of the second pillar would deteriorate fiscal sustainability relatively quickly in the baseline scenario. This result suggests that the Hungarian pension reversal would reduce deficit and debt only temporarily, mainly because of Hungary's costly defined benefit first pension pillar: the weakening of the second pillar is tantamount to swapping low current replacement rates (in the defined contribution second pillar) against high future replacement rates in the defined benefit first pension pillar.     

The Harvard Living Wage Campaign: Origins and Strategy

A member of the Harvard living wage campaign explains its internal development. Begun in 1998, the campaign drew inspiration from the global justice movement, organized labor’s reawakening, and the flowering of college anti-sweatshop groups. Locally, it responded to a decade of attacks on Harvard workers’ livelihoods and unions, as well as the enactment of a living wage ordinance by the city of Cambridge. The article recounts the campaign’s organizing strategy and tactics, its oppositional relationship to the Harvard administration, and the university’s response. Finally, it discusses the campaign’s limited victory on wages and contracting policies, as well as its significance for campus unions, students who participated, and student-labor mobilization beyond Harvard.     

The Price-Wage Mechanism in Poland: An Endogenous Switching Model

This paper proposes a two-equation price-wage model that enables to test whether the inflationary pressure on wage rate is only present when the rate of inflation is greater than some threshold value. Since the likelihood function for this model is very nonstandard, we develop a small-sample Bayesian approach to estimate its parameters. Our empirical results for Poland, 1962–1993, give support to the hypothesis of the price- wage spiral with a positive threshold value of inflation. This revised version was published online in July 2006 with corrections to the Cover Date.     

The price-wage inflationary spiral in Poland

In this paper the problem of price-wage relationship modelling in the case of a mixed economy is addressed. The empirical investigation was based on Polish annual data for the period of a centrally planned system (1964–1989) and on quarterly data for the period of transition towards a market economy (1990.1–1990.3). The traditional approach proved to be inappropriate because of the variables' nonstationarity. Identification of long-run behaviour was attempted by applying the two-step Engle-Granger's, or alternatively, Johansen's maximum likelihood (ML) procedures. The ML estimator provided better estimates of cointegration vectors and, even more important, allowed as many as three to be found.The main conclusion which can be drawn from the empirical findings is that three variables: price index, average wages and labour productivity, form a multi-dimensional equilibrium space. This property of the described phenomena needs to be taken into serious account when building macroeconometric models explaining the behaviour of the Polish economy.The existence of these three cointegration vectors is troublesome because of unusual problems of interpretation. However, if it is not as a result of misspecification and/or small sample bias, it proves that much remains to be learned about the price-wage mechanisms functioning in economies having a mixed character.

Housing differences in the late Soviet city: the case of Tartu,Estonia

Research on the residential and housing differences of urban populations in post‐second world war Central and Eastern Europe has a tradition extending back to the 1960s. Most studies have focused on the Polish, Czech and Hungarian (large) cities using aggregatelevel data and testing simultaneously the impact of a few factors on residential and housing differences. This research clarifies the housing differences in the late Soviet era of Tartu (the second largest city in Estonia). Using the individual‐level data of the 1989 Soviet census and multivariate methods, the article demonstrates that several factors (age, education, occupation, employment sector, ethnic origin, place of origin) shape the individual's housing and living conditions in the late Soviet period in Tartu. On the one hand, the results support the importance of the policy of different institutions (state, enterprises) in shaping people's living conditions; on the other hand, they also point to people's resources and desires as the cause.     

Exchange rate, inflation and unemployment in East European economies: the case of Poland and Hungary*

The aim of the paper is to model the impact of exchange rate on both inflation and unemployment variables in economies which are characterized by important structural changes, i.e. a transition phase moving from centralized economies towards market economies. This phenomenon, which is common to the East European countries, stressed different effects both for what concerns the behaviour of economic agents and for what concerns fiscal and monetary measures adopted by governments and aiming to keep under control the inflation–unemployment trade off. Time series relationships between these variables are investigated within an econometric model. Economic theory and the available data on the hypothetically relevant variables, along with the consideration of the main facts occurred in the period under study, characterize our information set. It is found that single equation analysis yields inefficient inference relative to the whole system analysis, and important structural changes are detected which reflect possible breaks in the structure of the economic system along with a change in economic policy.
