In summary, substance abuse is a serious problem in America. In fact, a Gallup poll ranked drug use as the Nation's number one problem. As a rapidly accelerating component of health care costs, charges for alcohol and drug abuse treatment are helping to drive up medical care expenses. The substance abuse crisis is also affecting employers, both public and private, who are struggling to provide needed health benefits while controlling spiraling plan costs. Despite the upward pressure on health costs, the problem is so serious that there has been a steady increase in the incidence of coverage for substance abuse treatment in employer-provided medical care plans, to the point that virtually all plans now provide some benefits. Nevertheless, health plans typically cover substance abuse treatment on a more restrictive basis than other illnesses. This may change, however, as the interest in, and the need for, comprehensive substance abuse treatment benefits grows. 相似文献

Team up to meet child-care needs 总被引:1,自引:0,他引:1
Thaler-Carter RE 《HRMagazine : on human resource management》1990,35(3):44, 46, 48
Recognizing the importance of child care is not the same as providing it. The options for many employees are limited, but some employers are trying to assist employees with their child-care needs. One option that benefits many small to medium-sized companies is a child-care consortium. 相似文献

Recent theoretical developments have incorporated endogenous multinational firms into the general–equilibrium model of trade. One simple taxonomy separates the theory into "vertical" models, in which firms geographically separate activities by stages of production, and "horizontal" models, in which multiplant firms duplicate roughly the same activities in many countries. The authors nest a horizontal and a vertical model within a hybrid (unrestricted) "knowledge–capital model" and estimate the specifications with data on US foreign direct investment activity. In the nested econometric tests, the data sample cannot distinguish statistically between the unrestricted model and the restricted horizontal model, indicating that the latter captures virtually all of the determinants of FDI. The tests overwhelmingly reject the vertical model. 相似文献
