Key risks and threats of the long-term development of the Russian economy, originating from the social sphere, are revealed and analyzed. The article focuses on human capital development and replenishment problems, as well as on the social effects of these problems on education, health conditions, labor migration, and pension provision.  相似文献

December 1, 1996 a new law was implemented in Portugal to gradually reduce the standard workweek from 44 to 40 h. We study how this mandatory reduction affected employment through job creation and job destruction. There was considerable regional, sectoral and firm-size variation in the share of workers who were affected by the working hours reduction. We exploit this variation to assess the impact of the workweek reduction. We find evidence that the working hours reduction had a positive effect on employment through a fall in job destruction.  相似文献

In this study, we investigate the effects of stock short-sale constraints on options trading by exploiting two US Securities and Exchange Commission rule changes under Regulation SHO: Rule 203 (locate and close-out requirements) and Rule 202T (temporary removal of short-sale price tests). We find that stock short selling activities decrease (increase) significantly after Rule 203 (Rule 202T) implementation, supporting the validity of Rule 203 (Rule 202T) as an exogenous increase (decrease) in short-sale constraints. Options volume increases significantly after Rule 203 went into effect and the result is more pronounced among firms with lower levels of institutional ownership and smaller options bid-ask spreads. Therefore, the evidence from Rule 203 suggests that investors may use options as substitutes for stock short sales when short selling is less feasible or more costly due to the locate and delivery requirements. In contrast, we find no significant change in the options trading volume of pilot stocks during the pilot program of Rule 202T. Overall, our results indicate that the impact of short-sale constraints on options trading varies with the types of constraints affected.  相似文献

Transparency research related to the regulatory process would benefit most from two types of empirical studies. One batch of studies, described in the fifth section of this essay, would focus on the American states and the member states of the European Union to identify the factors that determine whether regulatory processes are more transparent and whether transparency is successful in improving regulations and the regulatory process. In other words, we need comparative state (for the US) and member state (for the EU) studies to develop metrics for the quality of regulations and the role of transparency is advancing or weakening the quality of regulations at the state (for the US) and member state (for the EU) level. The second batch of studies, described in the sixth section of this essay, would explore who uses the information currently provided at the levels of transparency currently available in regulatory processes at the European Union and federal government of the United States. Who benefits from transparency and how are they using the available transparency mechanisms?  相似文献
