Recent academic research suggests that the effects of inward foreign direct investment for productivity and employment may vary across foreign investors with different characteristics. Using a newly created dataset that integrates micro-level information from The Netherlands Foreign Investment Agency and Statistics Netherlands, this paper explores the role of several of these characteristics, including e.g. the country of origin, activities and tasks, age and strategic role of foreign affiliates in The Netherlands in the 2000–2007 period. Our analysis shows that important employment and productivity differences exist for nearly all these dimensions.  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
