Analyzing synthetic cohorts in the 1980 and 1990 Public Use Microdata Samples, we find that Mexican‐Americans and other Hispanics acquired English fluency at a faster pace than Puerto Ricans and Cuban‐Americans during the 1980s. Additional results indicate that English‐skill investments differently influenced the earnings distributions of these ethnic groups. 相似文献

Investment, uncertainty and irreversibility 总被引:1,自引:0,他引:1
This paper investigates the irreversibility of investments and the impact this has on the nature of the relationship between investment and uncertainty. The empirical analysis uses firm‐level data and is based on a survey of 210 rice‐milling firms in the Mekong River Delta in Vietnam, which was carried out during the year 2000. We show that uncertainty reduces investment of rice millers in the presence of irreversibility, as is predicted by the real options approach to investment. We do not find evidence that the negative association between uncertainty and investment is influenced by the degree of irreversibility. 相似文献

Several studies find that bond rating downgrades cause negative valuation effects. Other studies find that signals conveyed by earnings releases, earnings forecasts, bankruptcies, and stock offerings of individual firms can be transmitted to their corresponding industries. By combining the two sets of studies, we hypothesize that bond rating changes may contain relevant information not only about the firm, but also about the corresponding industry. We find significantly negative valuation effects for rating downgrades, which are transmitted throughout the industry. Furthermore, we find that intra-industry effects depend on particular characteristics of the bond downgrade, the downgraded firm, and industry rivals. Specifically, the negative intra-industry effects are more pronounced when (1) the downgraded firm experiences a more severe share price response to the bond rating downgrade, (2) the downgraded firm is dominant in the industry, (3) the downgraded firm is more closely related to its rivals in the industry, and (4) the downgrade is due to a deterioration in the firm's financial prospects. 相似文献

We examine the impact of the events leading up to and including the passage of the Financial Services Modernization Act (FSMA) of 1999 on the stock returns of banks, brokerage firms, and insurance companies. We find that the impact is positive for all institutions. Bank gains are positively related to size and capitalization. Brokerage firms gain regardless of size, but the gains are inversely related to capitalization and insurance companies gain regardless of size or capital position. The strong positive reaction suggests that the market expects the institutions to benefit from the new opportunities created by the FSMA's passage. 相似文献

The maritime industry provides an interesting case study of the design and implementation of drug-testing programs in the
transportation industry during the 1980s. It is clear that such programs were designed and implemented less because of empirical
evidence of safety problems than for political reasons. The results in the maritime industry are indicative of a program that
is expensive to operate, intrusive with regard to employee privacy, and which will have little or no impact on safety. Focusing
such programs on the issue of impairment rather than on the issue of drug usage per se is likely to improve the outcome of
the programs.
Although, despite common belief, there is little evidence that drug usage or the “drug problem” in U.S. society as a whole
had gotten worse in the preceding years (Schonsheck, 1989, 250–251). 相似文献

We examine the impact of initial public offerings (IPOs) on rival firms and find that the valuation effects are insignificant. This insignificant reaction can be explained by offsetting information and competitive effects. Significant positive information effects are associated with IPOs in regulated industries and the first IPO in an industry following a period of dormancy. Significant negative competitive effects are associated with larger IPOs in competitive industries, those in relatively risky industries, those in high‐performing industries, and those in the technology sector. IPO firms that use the proceeds for debt repayment appear to represent a more significant competitive threat to rival firms relative to IPO firms that use their proceeds for other purposes. 相似文献

Announcements of syndication loans increase borrowers' shareholder wealth if they are revolving credit agreements but not if they are term loans. Share price responses to revolving credit announcements are positive and significant, whereas the wealth effect for term loans is negative and significant. The results show that announcements from both the financial press and commercial information providers can affect borrower share price reaction. Overall, single syndication announcements appear to be more newsworthy than multiple announcements reported in the financial press, and we find evidence of information leakage, post‐announcement drift, or both. 相似文献
