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. 相似文献

The work feasible portfolio is built into the work, that is, the k-dimensional Q column vector with components qi where qi 0 for i=1,...,k and q1+...+qk=1. We define i=1,...,k in the following way:

We generalize the concept of the natural rate of interest (Laubach and Williams, 2003; Woodford, 2003) by defining and estimating the natural yield curve (NYC) – the term structure of natural interest rates. Our motivation stems i.a. from the observation that at times when central banks attempt to directly affect long-term interest rates (e.g. via quantitative easing) the gap between the short-term real and natural rate is no more a good indicator of the monetary policy stance. We estimate the NYC on US data, document its main properties and show i.a. that in the period 2008 to 2011 the NYC allows to better capture the US monetary policy stance than the short-term natural rate. 相似文献

This article builds on the contingency approach to global leadership to examine empowerment in a cross-cultural context. Drawing upon ethnographic research on employees of a French NGO in Madagascar, our study demonstrates that effective empowerment is not dependent on the amount of delegation, but rather it is dependent on how delegation is performed. Understanding the cultural representations of formalization, skill development, collective work, and decision-making appeared to be crucial to effective delegation in Madagascar. This result suggests that managers should adapt the way that they empower their teams based on the conditions and forms of delegation prevailing in local cultures. 相似文献

The aim of this article is to evaluate the external and internal factors motivating the selection of business services to be outsourced by key meeting-industry (business tourism) players, with a particular focus on knowledge-intensive business services. The case-study method was adopted in the article to analyze the motivation behind outsourcing of knowledge-intensive business services by meeting venues and event companies in Krakow (Poland). The results confirm that event companies tend to subcontract out core services connected with the organization, promotion and/or management of events, event services, and technical support for events. 相似文献

Since the onset of the financial crisis significant interest rate spreads have arisen between euro area countries, both for public and private debt. We check whether these spreads could be made to work towards the goal of providing more stability to the euro area. In particular, we focus on reducing the imbalances that arose between the core and peripheral members of the euro area in the first decade of its existence. The idea is that stable positive spreads in peripheral countries could have decreased domestic demand, preventing the boom–bust cycles that plagued these economies. They could also prevent such developments in the future. We construct a panel model for euro area countries and estimate the relationship between real interest rates and the current account balance. Next, we use the estimated parameters to perform simulations. We find that spreads on real interest rates of 0.6–5.5 percentage points would have been necessary to stabilize external positions of the four peripheral euro area member countries. 相似文献

This study measures hypothetical bias in CVM-based estimates of willingness to support a forest protection and restoration program in Poland. It does so in two parallel ways: within- and between-subjects. To this end, participants are asked to vote in a referendum on an NGO-led reforestation project for various per-capita cost levels. They do so either directly or, as a surprise continuation, after a hypothetical analogue. Both methods deliver a similar (and substantial) level of hypothetical bias – it is slightly higher, but not significantly so, in the between-subject comparison. This suggests that hypothetical bias in this context is not primarily driven by such factors as consistency seeking or impression management. 相似文献

It is well known that central bank policies affect not only macroeconomic aggregates, but also their distribution across economic agents. Similarly, a number of papers demonstrated that heterogeneity of agents may matter for the transmission of monetary policy to macro variables. Despite this, the mainstream monetary economics literature has so far been dominated by dynamic stochastic general equilibrium models with representative agents. This paper aims to tilt this imbalance towards heterogeneous agents setups by surveying the main positive and normative findings of this line of the literature, and suggesting areas in which these models could be implemented. In particular, we review studies that analyse the heterogeneity of (i) households’ income, (ii) households’ preferences, (iii) consumers’ age, (iv) expectations and (v) firms’ productivity and financial position. We highlight the results on issues that, by construction, cannot be investigated in a representative agent framework and discuss important papers modifying the findings from the representative agent literature. 相似文献

The Department of Justice recent case against Microsoft is that it should not be allowed to aggressively maintain control over the internet browser market with the objective of preventing the internet from becoming the platform that could ultimately destroy Microsoft's operating system market. The aim of this paper is not to attack the Department of Justice case. Rather, it is to argue that for consumers one monopoly dominating both the operating system and applications is better than two separate monopolies. In our model we integrate Cournot's theory of two goods that are jointly used in the production of a third composite good with the fixed-proportion model. Utilizing our model we develop a possible explanation for Microsoft's actions – protection of its monopoly profits in the operating systems package market. Additionally we show that the price of the final product is lower if one firm monopolizes all markets. Consequently, the ordered split-up of Microsoft by Judge Thomas P. Jackson, aiming at creating two separate companies, one that will produce the windows and the other the operating systems, will harm consumers. 相似文献

In the present economic situation, business failures are a matter of major concern to government and business alike. The current period of slow growth in France, and the rigidity of its productive system make it more important than ever to act to insure the survival of its industrial fabric. This necessity has found recognition in the fact that the French Parliament is now discussing a Government bill designed to head off business failures by means of a series of early-warning signals. Under this bill, the company auditors' obligation is widened to include the duty to report to the company any factor liable to compromise the continued operation of that firm. The context within which the Banque de France's ‘Centrale de Bilans’1 is currently pursuing its work favors the development of a discriminant function capable of detecting symptoms of business failure at the earliest possible opportunity. This work has been facilitated, and usefully guided, by Altman's pioneering research in this field since 1968, as well as by the work of Blum, Deakin, Edmister and Taffler, to rite just a few names from the Anglo-Saxon world. In France, the most recent research has been initiated by the CESA [Altman et al. (1974)] and pursued by Collongues, Sulzer, Conan and Holder, as well as by certain banks. But in this last case applications have remained strictly limited. 相似文献
