Information–driven trading at the Prague Stock Exchange: Evidence from Intra–Day Data

Many observers argue that informed and insider trading is widespread in the emerging financial markets of transition countries, yet rigorous treatment of this issue has been virtually non–existent. The current paper estimates the extent of informed trading on the Prague Stock Exchange (PSE) using intra–day transaction data. Our estimates confirm that the average share of informed trading is equal to 0.32, which is high relative to developed markets and varies considerably among stocks. Using the Easley et al. (1996) approach on the very best segment of the PSE we obtained a high average probability of informed trading. Since data used in this study cover the period after the major attempts to improve market regulations, our results indicate that the PSE needs further strengthening to recover credibility and to become a real source of corporate financing.

Public and Private Education in an Integrated Europe: Studying to Migrate and Teaching to Stay?

This paper investigates public and private choices between internationally applicable and country‐specific education when graduates are mobile. Human capital depends on innate skills and study effort with either type of education. It is shown that national governments provide too few students with internationally applicable education, and too many with country‐specific education. This effect is mitigated, but not entirely eliminated, by the introduction of a graduate tax, according to which graduates are required to pay part of their taxes to the country where they received their education, regardless of residence. However, private educational choices are socially optimal with suitably differentiated tuition fees.     

FDI对我国劳动力市场均衡发展的积极效应

FDI投资规模的扩大缓解了我国劳动力市场供大于求的非均衡状态,同时,FDI通过扩大对熟练劳动力的需求以及对员工的培训和外资企业的技术扩散效应提高了我国的劳动力素质.外资企业市场化、法制化的劳动力资源配置机制和管理手段也对我国的企业起到了积极的示范作用,促进了劳动力的自由流动和劳动力薪酬制度的合理化,健全了我国的劳动力市场制度建设.FDI从这三个方面对我国的劳动力市场均衡发展产生了积极的效应.     

户籍歧视对劳动报酬差异的影响

在我国，户籍歧视是形成劳动力市场分割的重要原因，它不但通过阻碍劳动力流动造成城乡收入差异，也会促成农民工和城镇工人之间劳动报酬的差异。本文利用中国健康与营养调查（CHNS）多年的数据，对我国户籍歧视影响劳动报酬差异的程度进行计算和分析。结论表明，近几年户籍歧视现象并没有明显改观，政府在制定相应政策时，仍需关注这方面的问题。     

Extending working hours: why not work 42 h rather than 38?—a CGE analysis for Germany

Faced with a record level of unemployment, the present debate in Germany is to extend the weekly hours of work. In this paper the employment effects of an economy-wide increase in weekly hours are quantified on the basis of a computable general equilibrium model for different specifications of the wage setting rule and the use of additional policy-induced public income. The simulation results back the argument of the opponents of longer working time that not more jobs will be created. However, when the higher tax revenues from GDP growth are used to reduce social security contributions, then the claim of the proponents that more jobs will be created can be supported.     

公允价值的引入对投资性房地产核算的税务影响

新会计准则对企业的税务影响主要是相对影响,着重表现在对企业所得税费用的影响,但也有绝对影响,即对应纳所得税额的影响。本文结合实例分析新会计准则在投资性房地产等业务处理上适度引入"公允价值"作为会计核算计量模式后的税务影响。

The Random Walk Hypothesis in the Emerging Indian Stock Market

This paper examines the random walk hypothesis in the emerging Indian stock market using daily data on individual stocks. The statistical evidence in this paper rejects the random walk hypothesis. The results suggest that daily returns earned by individual stocks and by an equally weighted portfolio show significant non–linear dependence and persistent volatility effects. The non–linear dependence takes the form of ARCH–type conditional heteroskedasticity and does not appear to be caused by nonstationarity of underlying economic variables. Though conditional volatility is time varying, it does not explain expected returns.
