This study enhances our understanding of the complex relationship between diversity and employee retention. The study found that positive perceptions of an organization's “diversity climate” were related to decreased turnover intentions and found support for the proposition that calculative attachment mediated this relationship. In addition, the study considered potential interactions with diversity climate perceptions in predicting calculative attachment and found support for satisfaction with pay as a moderator, but not supervisor effectiveness. Finally, the study determined that the benefits of a positive diversity climate may extend to all employees, including White men. ©2011 Wiley Periodicals, Inc.  相似文献

This research examines the impact of local and international market factors on the pricing of stock indexes futures in East Asian countries. The purpose of this paper is to present a study of the significant factors that determine the major stock indexes futures’ prices of Hong Kong, Malaysia, Singapore, South Korea and Taiwan. This study first investigates the relationships between Hang Seng Index Futures, KLCI Futures, SiMSCI Futures, KOSPI Futures, Taiwan Exchange Index Futures and local interest rates, dividend yields, local exchange rates, overnight S&P500 index and a newly constructed index, Asian Tigers Malaysia Index (ATMI). 11 years historical data of stock indexes futures and the economic statistics are studied; 10 years in-sample data are used for testing and developing the pricing models, and 1 year out-of-sample data is used for the purpose of verifying the predicted values of the stock indexes futures. Using simple linear regressions, local interest rates, dividend yields, exchange rates, overnight S&P500 and ATMI are found to have significant impact on these futures contracts. In this research, the next period close is predicted using simple linear regression and non-linear artificial neural network (ANN). An examination of the prediction results using nonlinear autoregressive ANN with exogenous inputs (NARX) shows significant abnormal returns above the passive threshold buy and hold market returns and also above the profits of simple linear regression (SLR). The empirical evidence of this research suggests that economic statistics contain information which can be extracted using a hybrid SLR and NARX trading model to predict futures prices with some degree of confidence for a year forward. This justifies further research and development of pricing models using fundamentally significant economic determinants to predict futures prices.

This paper provides a framework to understand how market size affects firms' investments in product differentiation in a model of monopolistic competition. The theory proposes that consumers' love of variety makes them more sensitive to product differentiation efforts by firms, which leads to more differentiated products in larger markets. The framework also predicts an inverted U ‐shaped effect of trade liberalization on product differentiation, with trade liberalization leading to more differentiated products when starting from autarky but then leading to less differentiated products as the countries approach free trade.  相似文献

Building on the resource‐based view (RBV) and competitive dynamics literatures, this paper proposes that considering resources or actions independently offers an incomplete understanding of the drivers of superior performance. Instead, we hypothesize that resources enable competitive actions and that when these actions leverage the firm's resources, superior performance results. We tested these hypotheses with panelized data on the technological resources and competitive actions of firms in the in‐vitro medical diagnostic substance manufacturing industry. The results provide substantial support for our hypotheses, specifically with respect to mediation. Our theory and results underscore how the integration of the competitive dynamics and RBV literatures can significantly improve our understanding of firm performance.

Founders of hybrid ventures encounter organizational tensions that can compel compromise in both their organizations' and their own personal values. Such compromises may, in turn, undermine founders' identification with their ventures. In a multi-case study analysis we examine why social entrepreneurs differ in their responses to organizational tensions, both at the firm- and individual-level, and how such differences relate to their venture identification. Specifically, our findings reveal that strategic decisions made in the context of values-based complexity are often accompanied by concerns regarding founder authenticity—that is, judgments about the alignment between founders' actions and the commitments or responsibilities associated with their identities as entrepreneurs. Yet, because founders differ in the basis from which they seek to maintain such alignment, these differences shape both hybridity management and subsequent venture identification. By unpacking such differences, our findings contribute new theory, bridging recent scholarship on founder authenticity with longstanding research on organizational identification and hybrid organizing.  相似文献

Market frictions inhibit the perfect replication of property derivatives, and define the property spread as a price measure in the incomplete real estate market. We identify transaction costs, transaction time, and short sale constraints as the main frictions in this market. Based on these frictions, we set up a framework of arbitrage free price bounds for property derivatives. In turn, we use observed derivative prices to determine the implied cost of the frictions. Lastly, we verify these values by using other research, which confirms the accuracy of our framework.  相似文献

At a theoretical level this article discusses Piketty’s hypothesis that the distribution of income and wealth tends to become more concentrated over time when the rate of return on capital is greater than the growth rate of real output. We develop a post Keynesian model of growth and distribution showing that once capital is differentiated from wealth, the increase in income and wealth concentration actually occurs when the rate of valorization of financial and real estate assets is greater than the growth rate of real output, and that this situation may be triggered by financial liberalization.  相似文献

Given the increasing importance of learning at work, we set out to examine the factors which influence workplace learning behaviour. The study investigated the influence of the job characteristics from Karasek's Job Demand Control Support model and the personal characteristic self‐directed learning orientation on workplace learning. A total of 837 workers, aged between 18 and 65, from different sectors and with different educational levels completed a paper questionnaire. Analysis revealed that job demands and self‐directed learning orientation constitute significant and positive predictors of workplace learning behaviour. The study can help organizations to create job structures that promote workplace learning.  相似文献
