A bstract . Antidiscrimination laws are designed to prompt employers to stop excluding black workers from jobs they offer and from treating them unequally with respect to promotion and salaries once on the job. However, a moral hazard effect can arise if the existence of the laws leads black employees to bring unjustified claims of discrimination against employers. It has been argued that employers may become more reluctant to hire black workers for fear of being subjected to frivolous lawsuits.
Using the Multi-City Study of Urban Inequality (MCSUI), we find that male and female black workers are far more likely than whites to report racial discrimination at work. This is the case even when a host of human capital and labor market factors are controlled for. Further, nearly all black workers who report they have been discriminated against on the job in the MCSUI Surveys also show statistical evidence of wage discrimination. This is not the case for white males or females. We find little evidence to support a moral hazard effect. 相似文献

This paper reports the process used by a US manufacturing company to assess supply chain risks within the context of an offshore sourcing decision. The case study company was faced with the objective of finding a new supplier for two of its major product lines. Five alternatives were considered: (1) sourcing finished goods from Mexico; (2) sourcing finished goods from China; (3) sourcing parts from China and assembly in the US; (4) sourcing parts from China, assembly in a Maquiladora in Mexico with investment; and (5) sourcing parts from China, assembly in a Maquiladora in Mexico with no investment in the venture. To find the best solution, action research methodology was combined with the application of the analytic hierarchy process (AHP). Through iterative and structured discussions, 17 risk factors were identified, which were subsequently grouped into main and sub objectives. AHP was then used to evaluate the importance of each risk factor, and to determine the best alternative. This study makes several contributions to the field of purchasing and supply management. First, it provides a comprehensive framework of empirically derived risk factors to be considered in an international sourcing context. Second, it shows how AHP can be used to assess these risk factors and alternatives as part of the framework to facilitate and support the final offshoring decision. And third, it illustrates the successful application of the approach by a US manufacturing company. As such, this paper contributes to the research streams of offshoring and risk management in purchasing and supply, as well as to decision-making under uncertainty and AHP. In addition, it serves as a practical methodology for firms in similar situations. 相似文献

This paper empirically examines the acquisition of a technology from a source outside the firm and its incorporation into a new or existing operational process. We refer to this key activity in process innovation as external technology integration. This paper develops a conceptual framework of external technology integration based on organizational information processing theory and technology management literature. The primary hypothesis underlying the conceptual framework is that external technology integration will be most successful when the level of interaction between the source of the technology and recipient of the technology is appropriately matched, or fit, to the characteristics of the technology to be integrated. The conceptual framework also develops other hypotheses relating to contextual factors that may also influence the success of external technology integration. A cross-sectional survey methodology is employed to test the four hypotheses of the conceptual framework, with the results indicating strong support for the fit hypothesis and general support for the contextual hypotheses. The paper closes with a discussion of the implications of this study for both theory and practice. 相似文献

Process improvement programs such as Six Sigma, Lean, and Lean Sigma are very important and deserve serious academic research
attention. However, definition problems make it difficult to study any specific type of process improvement program. Therefore,
this study defines two organizational level program management factors, Strategic Project Selection (SPS) and Project Management
Infrastructure (PMI), that are independent of any specific process improvement program. Drawing upon current literature, this
study develops and tests theoretical models that relate SPS and PMI to operational performance improvement and to each other.
Using empirical data collected from 53 supplier plants of one large high-tech firm, this study finds that at the plant level,
SPS mediates the relationship between PMI and operational performance improvement. This insight contributes to both theory
development and practice, suggesting that a viable strategy for a process improvement program’s success is to focus on PMI
in order to enhance SPS and ultimately improve performance.

In order to add to the understanding of the role of franchising in entrepreneurship and to help franchise systems improve
efficiency, the constructs of organizational leadership, hope, organizational commitment, and service quality perceptions
of franchised managers and franchisees are differentiated in the current study. For scholars and practitioners, the dynamic
relationship between entrepreneurship, franchisees, and management is an important triangle which merits further investigation.
While the results offered only that managers and franchisees differed statistically in service empathy, differences were noted
across all areas which approached significance but was limited due to the small sample size. Implications for future research
are discussed. 相似文献

We consider the mixed AR(1) time series model $$X_t=\left\{\begin{array}{ll}\alpha X_{t-1}+ \xi_t \quad {\rm w.p.} \qquad \frac{\alpha^p}{\alpha^p-\beta ^p},\\ \beta X_{t-1} + \xi_{t} \quad {\rm w.p.} \quad -\frac{\beta^p}{\alpha^p-\beta ^p} \end{array}\right.$$ for ?1 < β p ≤ 0 ≤ α p < 1 and α p ? β p > 0 when X t has the two-parameter beta distribution B2(p, q) with parameters q > 1 and ${p \in \mathcal P(u,v)}$ , where $$\mathcal P(u,v) = \left\{u/v : u < v,\,u,v\,{\rm odd\,positive\,integers} \right\}.$$ Special attention is given to the case p = 1. Using Laplace transform and suitable approximation procedures, we prove that the distribution of innovation sequence for p = 1 can be approximated by the uniform discrete distribution and that for ${p \in \mathcal P(u,v)}$ can be approximated by a continuous distribution. We also consider estimation issues of the model. 相似文献

Considering the presence of first order residual effects of treatments, a family of variance balanced changeover designs has been presented and universal optimality of the designs is established. The designs use only v experimental units and (v ? 1)/2 periods for v = 4t + 3 prime or prime power number of treatments; t being a positive integer. A special feature of the proposed designs is that ‘in the order of presentation of treatments to experimental units over periods, each treatment is once immediately preceded by only half of the other treatments and is immediately followed once by the remaining half of the treatments’. This characteristic results in reducing the size of the variance balanced designs considerably. 相似文献

This article proposes an alternative framework for understanding enterprise unionism by emphasizing political dynamics and the role of the state in labour relations. Our framework delineates the strategic behaviour patterns of each of the tripartite IR actors under collective bargaining. It maintains that the initial period of the collective bargaining era constituted a critical juncture for state labour policy that occurred in distinctive ways in different countries and that these differences played a central role in shaping the different union structures in the following decades. Our historical analysis shows that unlike its Western counterparts, the Japanese state was able to eradicate the horizontal union movement at the onset of the collective bargaining era because of its advantages as a late developer and Cold War politics, which resulted in enterprise unionism in Japan. 相似文献

Nurse rostering is a complex problem. We propose a new heuristic using a competitive agent-based negotiation that focuses on nurse preferences called competitive nurse rostering (CNR). Unlike the existing literature, CNR models each nurse's preference functions separately and separates the cost minimization and preference maximization problems. CNR produces quality nurse rosters even though it cannot leverage extra staffing. As an agent system, CNR can distribute computational requirements over several computer systems, include other solution methods at various points in of the rostering problem, and act as a real-time scheduling system. These benefits are not naturally inherent in centralized heuristic solutions. 相似文献
