This study examined how entry‐level employees interacted with social media during three stages of organizational socialization. They navigated between four different media affordances (persistence, editability, visibility, and association) while experiencing them as both enabling and constraining in different socialization stages. Qualitative interview data analysis revealed during anticipatory socialization, job applicants realized visibility and persistence in relation to institutional and individualized socialization. During encounter, new employees managed personal and professional life boundaries carefully against the association and visibility affordances. Although some participants used both public and enterprise social media for obtaining job‐related information and understanding coworkers and company culture, during metamorphosis, most interviewees adopted passive information seeking strategies and experienced a paradoxical tension between the enabling and constraining affordances of social media. Findings are discussed with regards to employees’ exertion of agency in managing their professional impressions and coping with high levels of uncertainty and vulnerability during early stages of socialization.  相似文献

Firms developing new products often face the challenge of making investment decisions under uncertain input–cost conditions due to the price volatilities of the materials they use. These decisions need to be made long before the final products are launched on the market. Therefore, firms that invest in the opportunity to switch materials in a timely manner will have the flexibility to react to material price changes and realize competitive advantages. However, volatile material prices may also cause a firm to delay investment. Using real‐options reasoning, this paper studies the influence of input‐cost fluctuations on the timing decision to start new product development (NPD) and thus create the follow‐on opportunity to later replace an existing product. A model that combines waiting and switching options to derive influencing factors of the flexibility value that triggers the investment is developed and tested on a sample of material substitution projects from manufacturing firms. The results show how price uncertainty of the new and the old material, their joint price development, the expected project duration, and competitive preemption are related to the propensity to delay the start of NPD. The findings provide new insights on how timing in adopting materials can be used to hedge exposure to volatile material prices. The insights are relevant for adopters and producers of new materials, as well as for policy makers who strive for supporting the diffusion of new materials.  相似文献

The monopoly and monopsony power of intercollegiate sports create significant rents, but previous studies of intercollegiate football coaches’ salaries implicitly assume that coaches are paid their marginal revenue products. In a two-stage estimation, we show that coaches share in these rents. The first stage shows that several common measures of coaches’ productivity do not affect an athletic department’s variable revenue. When we include these measures in the second-stage salary equation, their impact on pay reflects bargaining power, not productivity. We also find that several measures of fixed revenue, which are independent of the coach’s performance, increase the coach’s pay.  相似文献

Business alliances, by filling critical resource gaps, enable firms to have positional advantages that lead to superior financial performance. Some alliances, however, are more successful than others. The three prominent theoretical approaches to explaining alliance success rely on resources, competences, and relational factors. The authors theorize that the three approaches are interdependent and, using resource-advantage (R-A) theory as a framework, develop an integrative model. This model proposes that the three approaches are linked by means of relationships among (1) alliance competence, (2) complementary resources, (3) idiosyncratic resources, and (4) cooperation. A test of the model, using a sample of alliance professionals, finds support for the theory that the three approaches are, indeed, interdependent and that resources, construed in the manner of R-A theory, influence alliance success through positional advantage.  相似文献

The purpose of this paper is to provide new empirical evidence on frontier efficiency measurement in the international insurance industry, a topic of great interest in the academic literature during the last several years. A broad efficiency comparison of 6462 insurers from 36 countries is conducted. Different methodologies, countries, organizational forms, and company sizes are compared, considering life and non-life insurers. We find a steady technical and cost efficiency growth in international insurance markets from 2002 to 2006, with large differences across countries. Denmark and Japan have the highest average efficiency, whereas the Philippines is the least efficient. Regarding organizational form, the results are not consistent with the expense preference hypothesis, which claims that mutuals should be less efficient than stocks due to higher agency costs. Only minor variations are found when comparing different frontier efficiency methodologies (data envelopment analysis, stochastic frontier analysis).  相似文献

We investigate whether Australian fund managers are able to deliver persistent performance using Carhart’s (1997) four‐factor model. Short‐ and long‐term persistence is examined and the sample is also divided into unit trusts and superannuation funds. We do not find evidence of persistence in any sample of funds. We find that winner (loser) funds tend to hold past winner (loser) stocks. Winner and loser unit trusts both appear to have positive exposure to small stocks.  相似文献

This study seeks to disentangle the effects of size, book‐to‐market and momentum on returns. Initial results show that each characteristic has a role in explaining returns, but that there is interaction between size and momentum, as well as between size and book‐to‐market. Three key findings emerge. First, the size premium is the strongest, particularly in the loser portfolios. Second, the value premium is generally limited to the smallest portfolios. Third, the momentum premium is evident for the large‐ and middle‐sized portfolios, but loser stocks significantly outperform winner stocks in the smallest size portfolio. When these interactions are controlled with multivariate regression, we find a significant negative average relation between size and returns, a significant positive average relation between book‐to‐market and returns, and a significant positive average relation between momentum and returns.  相似文献

Several studies report an asymmetry in the distribution of earnings around specified benchmarks. However, doubt has arisen over whether the observed ‘kink’ in the distribution of earnings is solely caused by earnings management. We use a ratio analysis approach to examine a range of specific accruals for evidence of earnings management. We find little evidence that firms immediately above the benchmark have abnormal receivables, inventories or provisions. However, they do increase cash‐from‐customers and reduce inventory. Thus, our results support the recent research that suggests that firms engage in real actions to meet earnings benchmarks.  相似文献
