A number of states have adopted laws that require employers to use the federal government's E‐Verify program to check workers' eligibility to work legally in the United States. Using data from the Current Population Survey, this study examines whether such laws affect labor market outcomes among Mexican immigrants who are likely to be unauthorized. We find evidence that E‐Verify mandates reduce average hourly earnings among likely unauthorized male Mexican immigrants while increasing labor force participation among likely unauthorized female Mexican immigrants. Furthermore, the mandates appear to lead to better labor market outcomes among workers likely to compete with unauthorized immigrants. Employment rises among male Mexican immigrants who are naturalized citizens in states that adopt E‐Verify mandates, and earnings rise among U.S.‐born Hispanic men. There is no evidence of significant effects among U.S.‐born non‐Hispanic whites. 相似文献

Using a sample of large US firms, this study shows that blockholders in combination with liquidity can contribute positively to innovation (R&D investments). We contribute to the literature on managerial myopia that has focused mainly on large owners and their type (short-term/long-term). Our results are in line with recent theoretical studies arguing that blockholders in combination with market liquidity can mitigate managerial myopia, as suggested by the exit model of governance. The results indicate that blockholders can be efficient in resolving agency problems and that they can enhance long-term prosperity, even when the individual blockholder investment horizon may not be long. 相似文献

The effect of the minimum wage on employment and hours 总被引:1,自引:0,他引:1
This study examines the effect of minimum wage increases on teen hours of work and employment using both state- and individual-level panel data in the US. The state-level results indicate that minimum wage increases may lower employment rates but do not adversely affect hours among either working teens or all teens. The individual-level results do not indicate that minimum wage increases have a significant negative effect on hours worked by low-wage teens who are likely to be affected by a minimum wage increase. The results suggest that low-wage teens are less likely to remain employed, relative to high-wage teens, when the minimum wage is raised. However, this adverse effect disappears when these low-wage teens are compared to other low-wage teens during periods when the minimum wage did not increase. 相似文献

This paper explores the psychological phenomena of sex stereotypes and their consequences for the occurrence of sex discrimination in work settings. Differential conceptions of the attributes of women and men are shown to extend to women and men managers, and the lack of fit model is used to explain how stereotypes about women can detrimentally affect their career progress. Commonly-occurring organizational conditions which facilitate the use of stereotypes in personnel decision making are identified and, lastly, data are provided demonstrating the way in which affirmative action programs and practices can act to promote the stereotyping of women suggesting, that rather than being a remedy for sex discrimination, such programs might in fact be another contributor to the problem. Conclusions focus on the importance of attending to the role sex stereotypes play in hindering women's career progress when procedures to combat sex discrimination in organizations are designed and implemented. 相似文献

Previous authors have documented reviews for design projects prior to construction [1,2]. Very little has been written about research reviews and systems to adequately review new projects. Within the Dow Chemical U.S.A. Research community, a different set of procedures have been developed at each site. The process discussed in this report is the most documented review system of any site within Dow Chemcial U.S.A. Research. 相似文献

AbstractAims: To evaluate the cost-effectiveness of adjuvant pembrolizumab relative to observation alone following complete resection of high-risk stage III melanoma with lymph node involvement, from a US health system perspective.Materials and methods: A Markov cohort model with four health states (recurrence-free, locoregional recurrence, distant metastases, and death) was developed to estimate costs, life-years, and quality-adjusted life-years (QALYs) associated with pembrolizumab vs observation over a lifetime (46-year) horizon. Using a parametric multi-state modeling approach, transition probabilities starting from recurrence-free were estimated based on patient-level data from KEYNOTE-054 (NCT02362594), a direct head-to-head phase 3 trial. Post-recurrence transition probabilities were informed by real-world retrospective data and clinical trials in advanced melanoma. Health state utilities and adverse event-related disutility were derived from KEYNOTE-054 trial data and published literature. Costs of drug acquisition and administration, adverse events, disease management, and terminal care were estimated in 2018?US dollars. Deterministic and probabilistic sensitivity analyses were conducted to assess robustness.Results: Over a lifetime horizon, adjuvant pembrolizumab and observation were associated with total QALYs of 9.24 and 5.95, total life-years of 10.54 and 7.15, and total costs of $489,820 and $440,431, respectively. The resulting incremental cost-effectiveness ratios (ICERs) for pembrolizumab vs observation were $15,009/QALY and $14,550/life-year. Across the range of input values and assumptions tested in deterministic sensitivity analyses, pembrolizumab ranged from being a dominant strategy to having an ICER of $57,449/QALY vs observation. The ICER was below a willingness-to-pay threshold of $100,000/QALY in 90.2% of probabilistic simulations.Limitations: Long-term extrapolation of outcomes was based on interim results from KEYNOTE-054, with a median follow-up of 15?months.Conclusions: Based on common willingness-to-pay benchmarks, pembrolizumab is highly cost-effective compared with observation alone for the adjuvant treatment of completely resected stage III melanoma in the US. 相似文献

In the debate over immigration reform, a common assertion is that immigrants take jobs that U.S. natives do not want. Using data from the 2000 Census merged with O*NET data on occupation characteristics, I show that the jobs held by immigrants are more physically arduous than the jobs held by U.S. natives. However, data from the California Work and Health Survey on self‐reported physical job demands indicate that immigrants do not perceive their jobs as requiring more physical effort than U.S. natives. Immigrants thus have worse jobs than natives but do not view them as such. 相似文献
