我国房地产税制的现状及改革构想

房地产税制是维护房地产市场公平竞争，实现国家对房地产业宏观调控的有力杠杆。然而，我国现行的房地产税制却存在税费不分、税制不统一、税制结构不合理等诸多问题。严重影响了其对房地产业应有的宏观调控作用。因此，适时地推进房地产税制的改革应是当务之急，应统一内外税制，合理界定税费的范围，建立统一、规范、合理的房地产税收体系。     

The Change in Productive Efficiency in Telecommunications in the United States

The question addressed here is whether the adoption of incentive regulation, which has become an important regulatory tool in the telecommunications industry in the USA, has resulted in a change in the technical efficiency of local exchange carriers in the USA. After providing an overview of the nature of incentive regulation, a methodology for measuring technical efficiency and its change is introduced. This is a multiple-output/multiple-input distance function approach to measuring technical efficiency. The results of implementing this approach for 19 local exchange carriers for the 1988-2001 period indicate that in the production of local service, intrastate toll/access service, and interstate access to local loops, there was no change in technical efficiency between the 1988-1990 period and the 1991- 2001 period, something that incentive regulation was specifically designed to promote.

Age Discrimination in Employment in Canada

Issues pertaining to age discrimination in employment in Canada are analyzed with a view toward highlighting lessons that may be learned from the Canadian experience—an experience that is taking on increased policy importance. Reasons for the increased attention to age discrimination issues are outlined, followed by a portrayal of the age discrimination legislation and court interpretations in Canada, especially as they pertain to mandatory retirement. Enforcement aspects are discussed, as is the evidence on age discrimination in employment and the effectiveness of legislation with respect to age discrimination and mandatory retirement. The article concludes with a discussion of the lessons to be learned from the Canadian experience, especially with respect to the poorly understood but complicated relationship between age discrimination and mandatory retirement. Policy recommendations for strengthening age discrimination legislation are also outlined. (JEL J14 , J24 , J71 )     

Inequalities in Income Distribution in Slovenia

This article presents an empirical analysis of income distribution based on income tax data for Slovenia in 1991-2000. It presents evidence of rising inequalities in income distribution (gross income, gross wages and pensions). These results are supported by coefficients of variation, Gini coefficients and by the Lorenz curves. Inequalities increased rapidly in the 1991 to 1993 period. After a significant decrease in 1994 and a steady increase from 1995 to 2000, the peak value from 1993 was not surpassed. Atkinson's requirements for dominance comparisons are not violated. Inequalities are also present in the distribution of the benefits of economic growth among income groups.

Public participation in forestry in Turkey

Recently public participation in forestry has been seriously considered in Turkey. Participation is however quite a challenge for a country with a long tradition of top-down management and a strong bottom-up dependence on public provisioning. In such a setting, it may not be surprising that the experiences with public participation in forestry in Turkey are mixed. There are some positive initiatives like the creation of farmer's cooperatives and NGOs, but their role is quite limited and small of scale. This paper is bringing together different views based on existing studies in Turkish related to Turkey's experience with implementing public participation in forestry.     

Inter-enterprise arrears in economies in transition

In the context of economies in transition, the paper argues that an excessive liquidity squeeze could throw the economy into a persistent state of low economic activity. In such bad equilibrium, enterprise transactions become largely demonetized, with a chain of arrears, a form of involuntary credit, spreading over the entire system. The empirical analysis of the Romanian experience seems to support the view advanced in the paper.
