Over the next 20 years, many organizations will experience significant shortages of skilled workers. At the same time, because of longer lifespans and a gradual rise in what society has considered the traditional retirement age of 65, older workers will represent a growing proportion of the American workforce. For a variety of reasons, many of these older workers desire to continue working and, if retained and engaged, they constitute a significant labor source for mitigating the emerging shortages of skilled workers. However, many organizations are not prepared to take advantage of this demographic shift; some even generate barriers that impede the retention and engagement of older workers. In this article, we identify a variety of ways in which organizations can retain and engage older workers to meet their staffing needs and enhance organizational performance. We also discuss the relationship of these proposals to prominent theories of motivation in management. 相似文献

In this paper, we argue that consideration of firm strategy can help illuminate the choices managers make between debt and equity financing. Within an industry, the form of competition that each firm chooses will determine the strategic value to the firm of maintaining financial slack. Our empirical analysis yields strong support for the proposition that financial slack should be a particularly critical strategic imperative for firms pursuing a competitive strategy premised on innovation. We also demonstrate that firms pursuing such a strategy that fail to recognize the value of financial slack are likely to perform poorly. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

Lead markets, innovation differentials and growth 总被引:1,自引:0,他引:1

This article suggests that the specialization of countries in international trade is determined by the lead-lag market pattern of national markets. Many internationally successful innovations have been adopted first in one country while other countries initially either preferred other designs or an established product. A model for the international diffusion of innovations is presented in which nationally preferred innovation designs compete to become a globally dominant design. In this model, there are country-specific market attributes that increase the likelihood that the choice a country makes among alternative technologies is followed around the world. It is argued that technological knowledge gaps are not the origin of an international competitive advantage. Instead, a country gains a competitive advantage because a specific innovation design was adopted earlier than in any other country. This gives local firms a head start in producing, gathering marketing intelligence and securing the property rights of a globally successful innovation. In countries with lag market characteristics, domestic innovations are less likely to get adopted worldwide. Lag markets often switch from a domestic innovation design to a foreign innovation design, which increases imports. The lead-lag market explanation of trade specialization has implications for national policies. In this model domestic innovations do not always foster exports; idiosyncratic innovations induced by lag market contexts can hamper the export chances of local firms and in the end lead to an increase in imports. It is suggested that in order to increase exports, national policies have to distinguish between a domestic lead and lag market context in each industry. While in a lead market context, traditional policy instruments that enhance the rate of innovations are effective, in a lag market situation national follower strategies are more appropriate. 相似文献
