It has long been recognized that there is a tradeoff between exploration and exploitation. How organizations utilize resources across time and space will affect firm survival and growth. In this paper, we examine resource utilization and performance implications over time in an environment undergoing fundamental institutional transformation. Based on a large archive of Chinese government data from 1988, 1992, and 1996, the study finds that (1) the impact of resource utilization is contingent on the degree to which different resources are committed to factors of production, (2) the impact is curvilinear and only valid within an “optimal” range, and (3) the performance implications change over time. As firms enter later stages of the transitional process, efficiency becomes less important as they shift their strategic focus from exploitation to exploration, which requires more flexibility. These findings have significant bearing on the issue of upgrading technological competitiveness in China as the country becomes increasingly integrated in the global economy. Such insights may also have implications for other emerging economies in Asia.

基于MIT的14种商业模式原型,从商业模式角度,对中美上市公司的总量分布,4种资产类型的商业模式对比分析,发现各不相同,其原因是中美企业一个是追求企业现金流,一个是追求企业价值;作为创新主体一个是标准的“工业时代”的企业家群体,一个是标准的“信息时代”的企业家队伍.产业所处的周期也有所不同.基于中美之间的对比明晰了中国企业商业模式创新的路径:从一般的制造商到创新型制造商、从单一的商业模式到智能型商业模式、从加法型商业模式到乘法型商业模式等路径.  相似文献

This paper offers a novel explanation for the lower urbanization rate and great urban-rural inequality in China. Our study reveals that, heavy-industry-oriented development strategy will result in lower urbanization rate and higher urban-rural inequality. The greater the degree of heavy-industry-oriented development strategy is, the lower the urbanization rate is, and the higher the urban-rural inequality is. From a dynamic perspective, heavy-industry-oriented development strategy reduces the capital accumulation rate, which results in a slower progress of urbanization and a highly persistent urban-rural inequality. The higher the degree of heavy-industry-oriented development strategy, the slower the progress of urbanization, and the longer the urban-rural inequality will last. This mechanism can potentially explain the lower urbanization rate and higher urban-rural inequality in China under a unified framework.  相似文献

This paper investigates the impact of corporate spinoffs on executive compensation. We find no significant association between executive compensation and stock returns prior to spinoffs, but a significant positive association between the two afterwards. We also find evidence that corporate governance generally improves after the spinoff. In addition, the positive association between executive compensation and stock returns is more pronounced for firms with greater improvements in their corporate governance. Overall, our findings support the notion that spinoffs create value by reducing agency costs.  相似文献

Co-branded advertising, where advertisements feature two partnered brands from different categories, should ideally benefit both brands. We test this assertion by studying the effect of featuring a second brand in advertisements on ad and brand name memorability, and the role of category context on which brand is recalled. Our test covers online display advertisements for consumer-packaged brands paired with charity and retailer brands in three markets (USA, UK, and Australia). Independent sample comparisons across 54 brand pairs show that advertising two brands has a neutral effect on ad memorability and negative effect on brand memorability. Furthermore, the advertisement’s category context determines which of the brands is recalled. Our findings support a competitive interference theory of dual-brand processing, whereby the two brands compete for attention resources. The results have implications for the return on investment from advertising expenditure, which will vary substantively depending on whether the costs of advertising are shared or borne by one brand in the pair.  相似文献

The authors of this article describe an adaptation of the rent-seeking game by Goeree and Holt (1999) to the recruiting of athletes by NCAA Division I football and basketball teams. Students engage in an effort-based lottery, i.e., recruiting to sign a blue-chip prospect. The winner gets the prize—the player's marginal revenue product in excess of his grant in aid. Students recruit in three scenarios: by recruiting legally, by recruiting legally or with illegal bribes, and by offering wages to athletes in an auction. The authors demonstrate the game's use in a principles course, but it is easily adaptable to other courses. To aid instructors unfamiliar with sports and NCAA recruiting, they include a comprehensive lesson plan with suggested readings and multimedia.  相似文献

Aims: Adverse events (AEs) associated with treatments for metastatic colorectal cancer (mCRC) may compromise the course of treatment, impact quality-of-life, and increase healthcare resource utilization. This study assessed the direct healthcare costs of common AEs among mCRC patients in the US.

Methods: Adult mCRC patients treated with chemotherapy or targeted therapies were identified from administrative claims databases (2009–2014). Up to the first three mCRC treatment episodes per patient were considered and categorized as with or without the AE system/organ category during the episode. Total healthcare costs (2014 USD) were measured by treatment episode and reported on a monthly basis. Treatment episodes with the AE category were matched by treatment type and line of treatment to those without the AE category. Adjusted total cost differences were estimated by comparing costs during treatment episodes with vs without the AE category using multivariate regression models; p-values were estimated with bootstrap.

Results: A total of 4158 patients with ≥1 mCRC treatment episode were included (mean age?=?59 years; 58% male; 60% with liver and 14% with lung metastases; 2,261 [54%] with a second and 1,115 [27%] with a third episode). On average, two treatment episodes were observed per patient with an average length of 166 days per episode. Adjusted monthly total cost difference by AE category included hematologic ($1,480), respiratory ($1,253), endocrine/metabolic ($1,213), central nervous system (CNS; $1,136), and cardiovascular ($1,036; all p?Limitations: Claims do not include information on the cause of AEs, and potentially less severe AEs may not have been reported by the physician when billing the medical service. This study aimed to assess the association between costs and AEs and not the causation of AEs by treatment.

Conclusions: The most costly AEs among mCRC patients were hematologic, followed by respiratory, endocrine/metabolic, CNS, and cardiovascular.  相似文献

The decisions to attend college are analysed and nonparametric predictions compared to those obtained from the widely used logit model. The impacts of measured cognitive ability and proxies for high school quality on the decisions to attend college are examined for a sample of white and black males and females from the USA. Two different parameters of interest which isolate the effects of ability and high school quality on college entry decisions are described and estimated by ‘integrating out’ the effect of other covariates. It is found that measured cognitive ability is an extremely important determinant of college entry for all race and gender groups. At the same point in the ability distribution, blacks are more likely to select into college than whites, and females more likely than males of the same racial group. Proxies for high school quality such as teacher education, student teacher ratios, school enrolment and library size are shown to have little or no effects on the likelihood of college entry for all race and gender groups. Further, predictions obtained from the flexible nonparametric analysis are found to be quite similar to those obtained from the logit model, suggesting that simpler fully parametric binary choice models perform quite well as modelling college entry decisions.  相似文献

This study examines the determinants of earnings management in an international setting using the limited investor attention model of Hirshleifer and Teoh ( 2003 ). The model predicts that investor attention reduces earnings management. I use analyst following, institutional ownership, and Big N auditor choice to proxy for investor attention. I have four key findings. First, I document that financial analysts curb earnings management in U.S. firms but not in non‐U.S. firms. Second, I document that institutional block‐holdings curb earnings management across the world. Third, Big N auditors reduce earnings management in U.S. firms but not in non‐U.S. firms. Fourth, I document that corporate governance mechanisms reduce earnings management in U.S. firms but not in non‐U.S. firms.  相似文献
