The paper addresses the issues of poverty and social security in a transitional environment on the basis of recent economic developments in Bulgaria. Special emphasis is placed on the need for a new type of social safety net stemming from the radical changes in the political and economic system. The evolution of the social security system in Bulgaria during the transition is analysed focusing on such elements as the pension system, unemployment benefits, child allowances, etc. The empirical analysis is based on extensive use of data from the Bulgarian Household Budget Surveys during the period 1992–1996. Poverty in Bulgaria is measured using different poverty measurements and some quantitative results showing the changing dimensions of poverty in the transition period are presented and discussed in the paper.EES or e-mail at Corresponding author.

Evaluating the British Model of Electricity Deregulation   总被引:3,自引:0,他引:3  
Abstract ** :  A key aspect of the 1990 reforms to the British electricity supply industry was the introduction of a formal system of regulation by an autonomous regulatory body. It was expected that replacement of monopolies in some areas by markets and price‐setting in monopoly areas using a simple incentive formula would mean that regulation of the industry would be 'light'. This article examines how regulation has turned out in practice. It concludes that the promise of 'light' regulation has not been fulfilled. Regulation of competitive markets is a major regulatory activity, incentive regulation has evolved into a complex and intrusive form of rate‐of‐return, while regulation of industry structure has allowed the industry to descend into a concentrated, vertically integrated structure, at odds with the aims of the reforms .  相似文献

Market power in the input purchase is becoming increasingly common because of growing consolidation and mergers and also due to multinational firms establishing a stronghold in buying inputs in the developing countries. In this study, we formulate a general equilibrium model consisting of a competitive sector and an oligopsony sector which exercises market power over inputs. Our results indicate that if the oligopsony sector incurs a higher marginal factor cost for the intensive factor, basic results of the standard two-sector model continue to hold. But if the marginal factor cost is higher for the non-intensive factor, then factor intensities in the physical and value sense differ and traditional trade propositions such as the Stolper–Samuelson theorem do not hold.  相似文献

The purpose of this study is to examine the effects of State regulation that determines the extent of professional independence of advanced practice nurses (APNs). We find that in States where APNs have acquired a substantial amount of professional independence, the earnings of APNs are substantially lower, and those of physicians assistants (PAs) are substantially higher, than in other States. These results are striking since PAs are in direct competition with APNs; the only real operational difference between these groups is that PAs are salaried employees who must work under the supervision of a physician. The implication is that physicians have responded to an increase in professional independence of APNs by hiring fewer APNs and more PAs. The finding that earnings of APNs decline when they attain more professional autonomy vis-à-vis physicians reinforces work by Sass and Nichols on physical therapists.The content is the responsibility of the authors and does not represent official positions of the Federal Reserve Bank of St. Louis or the Federal Reserve SystemJEL classification: I11, I18, J31, J44, L51  相似文献

This study brings together the predominantly qualitative approach of social forecasting—as manifested by Daniel Bell's concept of the post-industrial society—and the quantitative analysis of econometric forecasting. The econometric model used here is the candide model of the Canadian national economy. The author seeks to verify the compatibility of some hypotheses of the post-industrial concept by using candide to develop a post-industrial scenario; in doing so, he obtains quantitative estimates of many critical features of the concept within the framework of a structured and reasonably consistent model.  相似文献

Conditional and Unconditional Conservatism:Concepts and Modeling   总被引:15,自引:1,他引:15  
We develop a model that captures the distinct natures of and interactions between conditional and unconditional conservatism. Under unconditional conservatism, the book value of net assets is understated due to predetermined aspects of the accounting process. Under conditional conservatism, book value is written down under sufficiently adverse circumstances, but not up under favorable circumstances. The specification of earnings provided by the model yields hypotheses about how unconditional conservatism and other factors preempt conditional conservatism and so affect the asymmetric response of earnings to positive and negative share returns, both current and lagged, documented by Basu (1995, “Conservatism and the Asymmetric Timeliness of Earnings.” Ph.D. dissertation, University of Rochester’ 1997, “The Conservatism Principle and the Asymmetric Timeliness of Earnings.” Journal of Accounting and Economics 24, 3–37).This revised version was published online in August 2005 with a corrected cover date.  相似文献

We examine the number of external appointments held by corporate directors. Directors who serve larger firms and sit on larger boards are more likely to attract directorships. Consistent with Fama and Jensen (1983), we find that firm performance has a positive effect on the number of appointments held by a director. We find no evidence that multiple directors shirk their responsibilities to serve on board committees. We do not find that multiple directors are associated with a greater likelihood of securities fraud litigation. We conclude that the evidence does not support calls for limits on directorships held by an individual.  相似文献

High-Water Marks and Hedge Fund Management Contracts   总被引:1,自引:0,他引:1  
Incentive fees for money managers are frequently accompanied by high‐water mark provisions that condition the payment of the performance fee upon exceeding the previously achieved maximum share value. In this paper, we show that hedge fund performance fees are valuable to money managers, and conversely, represent a claim on a significant proportion of investor wealth. The high‐water mark provisions in these contracts limit the value of the performance fees. We provide a closed‐form solution to the cost of the high‐water mark contract under certain conditions. Our results provide a framework for valuation of a hedge fund management company.  相似文献
