The literature on top‐down strategy implementation has overlooked social‐emotional factors. The results of a three‐year field study of a large technology firm show how top executives who favor an affect neutral task approach can inadvertently activate middle managers' organization‐related social identities, such as length of time working for the company (newcomers versus veterans) and language spoken by senior executives (English versus French), generating group‐focus emotions. These emotions prompt middle managers—even those elevated to powerful positions by top executives—to support or covertly dismiss a particular strategic initiative even when their immediate personal interests are not directly under threat. This study contributes to the strategy implementation literature by linking senior executives' actions and middle managers' social identities, group‐focus emotions, and resulting behaviors to strategy implementation outcomes.

This paper explores the relationship between migration and consumption patterns using panel data from the 2004 and 2006 Vietnam Household Living Standards Surveys. Employing an instrumental variable approach to control for the endogeneity of migration, our results indicate that short-term migration has a positive effect on overall per capita food expenditures, per capita calorie consumption and food diversity. Long-term migration also appears to be positively related to consumption, but impacts are often insignificant and of a lesser magnitude than short-term migration. The results provide no evidence of negative effects of migration, and support the view that short-term migration is a mechanism by which households maintain food security. The results suggest that to improve food security the Vietnamese government should enact policies that facilitate short-term migration flows as well as the transferring of remittances.  相似文献

Time series data arise in many medical and biological imaging scenarios. In such images, a time series is obtained at each of a large number of spatially dependent data units. It is interesting to organize these data into model‐based clusters. A two‐stage procedure is proposed. In stage 1, a mixture of autoregressions (MoAR) model is used to marginally cluster the data. The MoAR model is fitted using maximum marginal likelihood (MMaL) estimation via a minorization–maximization (MM) algorithm. In stage 2, a Markov random field (MRF) model induces a spatial structure onto the stage 1 clustering. The MRF model is fitted using maximum pseudolikelihood (MPL) estimation via an MM algorithm. Both the MMaL and MPL estimators are proved to be consistent. Numerical properties are established for both MM algorithms. A simulation study demonstrates the performance of the two‐stage procedure. An application to the segmentation of a zebrafish brain calcium image is presented.  相似文献

This paper investigates the nonlinear relationship between firm value and corporate cash holdings in a sample of non‐financial Vietnamese firms from 2008 to 2013. We focus on both static and dynamic regressions to test for a nonlinear relationship. Our results reveal an ‘inverse U‐shape’ relationship between firm value and cash holdings, which is in line with trade‐off theory. Specially, we further test whether the optimal cash level changes under different financial conditions. In turn, this paper shows evidence of a nonlinear relationship between firm value and cash holdings under different financial circumstances and that each type of firm will adjust its optimal cash level based on business conditions.  相似文献

We examine the announcement-period acquirer returns and target values for a large sample of cross-border acquisitions by U.S. firms, differentiating between private and public targets and paying particular attention to the legal protection of minority shareholders in the target country. For high-protection target countries, acquirer announcement-period returns are significantly negative for public targets and significantly positive for private targets. For low-protection target countries, the acquirer returns are significantly positive for public targets and insignificantly different from zero for private targets. For public targets, acquirer returns are decreasing and target-firm values and acquisition premia are increasing with the level of investor protection. For private targets, investor protection does not affect acquirer returns or target-firm values. We find that bidder returns decrease with the level of creditor protection in the target country and increase with the quality of accounting standards. Our results also show that in low- protection countries, firm-level corporate governance mechanisms, such as higher insider ownership, may substitute for the lower level of investor protection.  相似文献

We extend recently documented evidence that diversified firms hold significantly less cash than specialized firms to consider differences in how diversified and specialized firms adjust their cash flows to achieve their target cash balance. We find that diversified firms have higher free cash flows as a result of equal operating cash flows and lower investment in comparison to specialized firms. Diversified firms save less cash by placing less reliance on external financing; by issuing less debt and equity, and distributing higher cash dividends. Our findings support the hypothesis that diversified firms are able to hold less precautionary cash as they are in better position to finance investment opportunities internally from operating cash flows.  相似文献

This study examines the short-run and long-run inflation hedging effectiveness of gold in the United States and Japan during the period of January 1971 to January 2010. Previous research has shown in the long-run that inflation tends to appropriately increase the price of gold in the U.S., leading to gold's popularity as an asset in portfolios to reduce the risk against sudden inflation. However, gold is only partially effective in hedging against inflation in Japan. This research found that the rigidity between the price of gold and the consumer price index affects the inflation hedging ability of gold in the long-run. The gold price is characterized by market disequilibrium induced by the price rigidity, causing the price of gold to be unable to response to changes in the CPI. To explore the inflation hedging ability of gold in the short-run, this study further examines the price rigidity in low and high momentum regime. It is found during the low momentum regimes that, gold return is unable to hedge against inflation in either the U.S. or Japan. However, during high momentum regimes, gold return is able to hedge against inflation in the U.S., while the price rigidity in Japan causes the price of gold to not fully hedge against inflation in the short-run.  相似文献

Authenticity in tourism has been a topic of discussion since the 1960s, but the concept is still to be fully developed. This study focuses on tourists’ perceptions of authenticity, and in particular how they evaluate authentic heritage experiences. The appearance and physical settings of attractions were found to be the initial and most important indicators of authentic or inauthentic experiences. Other criteria for assessing the authenticity of heritage experiences include the presence of local culture and customs, constructed elements, commodification, and atmosphere.  相似文献

In this study, we investigate the effects of entrepreneurial orientation and marketing information on the performance of small and medium-sized enterprises. We build and test a causal model using data obtained from Singaporean entrepreneurs and find support for most of our hypotheses. The results indicate that entrepreneurial orientation plays an influential role on the acquisition and utilization of marketing information, and also has a direct effect on firm performance. The utilization of information regarding marketing mix decisions (particularly the Promotion and Place elements) positively affects firm performance, and it partially mediates the relationship between entrepreneurial orientation and firm performance. The implications and future research directions are discussed.  相似文献
