Despite recent interest in how psychiatric disorders affect work outcomes, little is known about the role of personality disorders (PDs), which are poorly understood yet prevalent (15%) and impairing. We used nationally representative data for 12,457 men and 16,061 women to examine associations of PDs with any employment, full-time employment, chronic unemployment, being fired or laid off, and having trouble with a boss or co-worker. Antisocial, paranoid, and obsessive-compulsive PDs demonstrated the broadest patterns of associations with adverse outcomes. Findings suggest that PDs may have implications for the productivity of co-workers as well as that of the disordered employees themselves.  相似文献

Dual sourcing strategies supplement inflexible, low-cost country sourcing with quick response manufacturing. Due to short product life cycles, combined with uncertain demand, dual sourcing strategies are very common in several industries, in particular in the sporting goods or fashion industries.Even though scholars have given some attention to the analysis of dual sourcing strategies, the importance of the decision-maker’s risk preferences has not been covered yet.In this paper we analyse dual sourcing strategies using an extended single-product newsvendor model with two order points. Different risk preferences will be modelled using an exponential utility function. Within realistic parameter ranges, the optimal order quantities can only be numerically computed. The findings of this paper show that dual sourcing strategies are always preferable to an exclusive offshore approach, as long as the onshore ordering costs are smaller than the selling price of the considered product. The more risk-averse the decision-maker, the smaller the offshore order quantity will be.  相似文献

The turbulent real estate market during the early 1990s coincided with the implementation of risk-based capital standards for commercial banks. In this study we use non-parametric linear programming techniques to identify the lost real estate lending due to bank inefficiency. Inefficiency may arise from one of three sources: risk-based capital standards which constrain bank real estate lending, inefficiency stemming from managerial oversight of real estate lending, and scale inefficiency which arises from banks not operating at constant returns to scale. The results indicate that the lost real estate lending associated with risk-based capital standards averaged 2.7% of total bank assets. However, banks could compensate by exercising better managerial oversight of real estate lending and by operating at constant returns to scale.  相似文献

Companies that seek to exploit the cost advantages of business-to-business (B2B) e-Commerce face a variety of strategic options. By analyzing the demand and cost functions for sellers, intermediaries, and buyers, this research develops an economic framework that clarifies the relative advantages of four common B2B e-Commerce channels: private exchange, web-based procurement, public aggregation, and public exchange. This research focuses on addressing two important questions: (1) How does a buyer select a suitable B2B e-Commerce channel (or an e-Marketplace structure) given a variety of market conditions, different levels of product substitution, and a range of purchasing patterns? (2) How does a buyer successfully manage a B2B e-Commerce channel for gaining the highest transaction-level buyer surplus? The analytic and numeric results of our study show that a company's product offerings, the market conditions it faces, and the purchase patterns it implements are all important determinants in the selection of B2B e-Commerce setting. For custom products, private networks (such as the private exchange or web-based procurement models) are more attractive than the public aggregation or exchange models. However, taking market conditions and purchasing behavior into consideration, the web-based procurement model is more suitable for spot purchasing, while the public exchange model is more suitable for systematic purchasing and fragmented markets. On the other hand, the aggregation model is preferable in concentrated markets while the exchange model is more suitable in fragmented markets. These results provide important implications for industrial development of B2B e-Commerce.  相似文献

Our paper provides a brief review and summary of issues and advances in the use of latent structure and other finite mixture models in the analysis of choice data. Focus is directed to three primary areas: (1) estimation and computational issues, (2) specification and interpretation issues, and (3) future research issues. We comment on what latent structure models have promised, what has been, to date, delivered, and what we should look forward to in the future.  相似文献

We argue that the stakeholder perspective on corporate social responsibility is in the process of being enlarged. Due to the process of institutional isomorphism, corporations are increasingly adopting organizational features designed to promote proactivity over mere reactivity in their stakeholder relationships. We identify two sources of pressure promoting the emergence of the proactive corporation -- stakeholder activism and the recognition of the social embeddedness of the economy. The final section describes four organizational design dimensions being installed by the more proactive corporations today -- cooperation, participation, negotiation, and direct anticipation.  相似文献
