This paper focuses on the analysis of wage-price relationships during the period 1980–1991 in Poland. The dynamics of wage and price series under radical structural changes are examined, as well as the impact of earlier sharp price increases. The process of wages-to-prices adjustment both in the long- and short-term is analysed. The hypothesis that the introduction of economic reform (at the beginning of 1990) would result in a tendency towards the stabilization of real wages is investigated. This is done through integration and cointegration analysis of wage and price series with special attention being paid to the problems arising from theI(2) character of the variables investigated. The concept of polynomial cointegration is applied to formulate error correction terms for the short-run model of wages. The computations have been made using quarterly data. The results reflect an inhomogeneity of the period investigated, especially the effects of the introduction of economic reform at the beginning of 1990. The nonstationarity of real wages is confirmed, but not their tendency towards stabilization. 相似文献

This paper describes Project SafeCare, an ecobehavioral research and treatment project with families reported or at risk for child abuse or neglect. Preliminary demographic data are reviewed along with indirect assessment data. Four case studies are described to exemplify the effects of training provided to families. The implications for the current assessment data, treatment, and outcome are discussed. 相似文献

On January 1, 1985, the mandatory seat belt law went into effect in New York State; violators were now subject to a fine of $50.00. Police officers issued nonpenalty-based warnings during the month prior to the law's imposition. The purpose of the present study was to compare the effects of the warning versus the fine and a fine-plus-prompt condition (the prompt delivered by the experimenters) on seat belt use on a university campus. Results indicated that significantly more drivers used their sear belts during the fine conditions as compared with the warning condition and that significantly more female drivers used their seat belt during all conditions. A significant difference was not found, however, between the fine and fine-plus-prompt conditions.We gratefully acknowledge the comments of Michael Leippe on an earlier draft of this manuseript. 相似文献

Not only a large number of developing countries but also transition economies have established free economic zones (FEZs) with the aim of attracting foreign capital by providing tax incentives, creating employment opportunities, and promoting exports and regional development. Tax investment promotion schemes include profit tax exemption, free or accelerated depreciation, investment tax allowance, subsidy for investment costs, etc., the effects of which on firms’ investment decisions can be compared based on the net present value model. This study suggests that even a low corporate tax rate combined with generous depreciation rules does not provide incentives for investors when the inflation rate is high. A case study on Najin–Sonbong FEZ in North Korea delivers a wide range of more crucial economic and political reasons why such a development project can fail, although tax concessions offered there are more favourable than those in China and other Asian nations. 相似文献

Past studies on the Racketeering Influenced and Corrupt Organizations Act (criminal RICO) are merged with research on organized crime and recently collected information on the presence of informants in appellate cases. After identifying problems associated with the statute since its enactment in 1970, attention is directed toward the place of informants within court proceedings applying criminal RICO. The central finding points to a relatively high presence of informants in such cases. The explanation that follows accounts for the prevalence of informants in RICO cases by combining: (1) the statutes liberal construction, (2) an increasing acceptance amongst government and law-enforcement officials that the use of informants is essential to the fight against the apparent organized crime threat, and (3) the rationalization that extends from the prosecutorial success that has been documented within the United States and in other countries that have adopted similar forms of legislation.We would like to thank Pierre Tremblay and Marie-Andrée Bertrand for their comments and suggestions on past versions of this paper. We also show our gratitude to Gerard Lynch for his help during early phases of this research. 相似文献

A 35-year-old man was found dead by his wife. He was reported to have had symptoms of a common cold the week preceding his death. The medicolegal autopsy yielded signs of central dysregulation (ectasia of the urinary bladder and rectum, dystelectasis of the lungs) together with marked brain edema and fresh bite marks on the tongue. The cause of death was presumed to be lethal epileptic seizure. Neuropathologic examination revealed neuronal nodular heterotopia as well as discrete lymphocytic meningitis (aseptic meningitis). The death was most probably caused by the combination of the meningitis with the occult malformation, leading to a lowered seizure threshold and subsequent lethal seizure. The morphologic findings of this case are presented, and the probable mechanisms of death are discussed. 相似文献
