The DoD annually procures billions of dollars worth of systems, supplies, and services in support of the national military strategy. Faced with budget cuts and other resource constraints, the DoD must transform its procurement process to ensure cost-effective sourcing of critical supplies and services. One aspect of current transformation in the DoD is the use of a strategic sourcing approach for the procurement of services at military installations. Using the Air Force's strategic sourcing process as our context, we developed an optimization model for selecting a set of proposals from among multiple offerors for services to be performed at multiple installations. The selection achieves the most favorable objective by balancing the confidence level in an offeror's past performance with the cost of services to the Air Force. The research findings, which are based on a realistic scenario, demonstrate improvements over the current sourcing process in both overall performance and cost.  相似文献

This study explores the simultaneous relationship between corporate cash holdings and dividend policy using a large sample of around 400 non‐financial firms for the period from 1991 to 2008. The results show that cash holdings are affected by dividends, leverage, growth, size, risk, profitability, and working capital ratio. Dividend policy is affected by cash, leverage, growth, size, risk, and profit. When controlling for simultaneity, dividend payments do not appear to significantly affect cash holdings, nor do cash holdings affect dividend policy. The empirical analysis suggests that simultaneity is crucial in analyzing corporate cash holdings and dividend policy. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

There is an increasing concern for the notion of ‘embeddedness’ of economic activity; yet the conceptualization of the concept and its operationalization remain underdeveloped. First, embeddedness may concern, on the one hand, the structure of relations that tie economic actors together (structural embeddedness) and, on the other hand, the social strands supplementing economic strands in each relation (substantive embeddedness). In this paper, a network framework is outlined which proposes several layers or ‘orders’ of embeddedness. Focusing on small firms, the point of departure is individual exchange relationships as personal ties combining economic and social concerns. First-order embeddedness concerns the localized business networks created by combining these dyadic relations. Second-order embeddedness is achieved when considering also the memberships of business persons in economic and social local institutions while third-order embeddedness concerns the special cases where these institutions bridge gaps between firms. The network model is operationalized and applied to a small Swedish industrial (furniture) community, its firms and economic/social institutions. The findings generally support the applicability of the model and demonstrate the supplementarity of different layers/orders of embeddedness. Further research challenges are deduced and implications for practitioners are provided.  相似文献

Accounting concepts dictate that separately disclosed components should contain separate useful information. This paper examines the relations between income statement components and analysts' earnings forecasts and forecast errors. Regressions explaining earnings forecasts using earnings components provide a better fit than regression using just aggregate income to explain forecasts. We interpret this as consistent with the hypothesis that analysts use incremental information in components not available in aggregate income. However, additional tests based on predictability of forecast errors indicate that analysts do not incorporate all information available in components into earnings forecasts. In addition, this inefficiency appears to increase at longer forecast horizons.  相似文献

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

Stochastic productivity indicators are defined, and superlative measures of these indicators are derived. It is shown that, in the presence of complete markets or a common-expectations equilibrium, differences in the market values of firms are superlative indicators of cross-sectional productivity differences. Exactness results are used to decompose nonstochastic productivity indicators into a measure of true productivity change and a measure of ‘luck’. The decomposition is illustrated empirically.

The aim of this paper is to offer an alternative to a priori theorising in research on firm-level growth and environmental sustainability. We outline an approach that combines John Shotter's phenomenology with post-hoc application of the Bourdieusian concepts of habitus, practices and social capital. This is illustrated empirically through a study conducted with a small group of Finnish entrepreneurs, which examines their lived experience of growth alongside its practical application in their ventures. The entrepreneurs' responses reveal holistic perspectives on growth that extend beyond the economic to incorporate personal commitments to norms of collectivity and well-being for themselves and others. The paper offers an exploratory but empirically grounded approach, arguing that a combination of insiders' perspectives and attention to the social embedding of economic activity challenge the dichotomous distinctions between sustainable and conventional entrepreneurship and reveal a degree of commonality that would not be evident via conventional categorisations on the basis of features such as business model type.  相似文献

In January 2014, Northwestern University (NU) football players filed a certification election petition with the National Labor Relations Board’s (NLRB) Chicago regional office. After the NLRB ruled that they were employees having the legal right to unionize, the football players voted at the end of April 2014 with NU immediately appealing the regional director’s ruling after the balloting. In mid-August 2015, the Washington D.C. NLRB declined jurisdiction in this case, ending the football players’ unionization attempt. Because of the NLRB’s appellate ruling, however, unionization of college athletes remains a distinct possibility. Since a majority of U.S. collegiate basketball and football players are black, this paper argues that the model of unionism that should be adopted in any unionization attempt of these college athletes is civil rights unionism which represents a continuation of the historic, collective struggle of Black athletes to obtain their rights on athletic fields and in classrooms.  相似文献
