In systems industries, combinations of components are consumed together to generate user benefits. Arrangements among component providers sometimes limit consumers’ ability to mix‐and‐match components, and such exclusive arrangements have been highly controversial. We examine the competitive and welfare effects of exclusive arrangements among system components in a model of relatively differentiated applications that run on relatively undifferentiated platforms. We show that there is no “One‐Market‐Power‐Rent Theorem.” Specifically, exclusive deals with providers of differentiated applications can raise platforms’ margins without reducing applications’ margins, so that overall industry profits rise. Hence, for a given set of components and prices, exclusive arrangements can reduce consumer welfare by limiting consumer choice and raising equilibrium prices. In some cases, however, exclusivity can raise consumer welfare by increasing the equilibrium number of platforms, which leads to lower prices relative to the monopoly outcome that would prevail absent exclusivity.  相似文献

Eco‐cities have attracted international attention from governments, corporations, academics and other actors seeking to use sustainable urban planning to reduce urban environmental impacts. China has devoted significant political will and economic resources to the development of new‐build eco‐city projects, reflecting the Chinese government's goals to build a ‘harmonious society' in which environmental sustainability and social stability are mutually reinforcing. We critically analyse the case of the Sino‐Singapore Tianjin eco‐city to demonstrate that the eco‐city's ecologically modernizing visions of eco‐urbanism construct a protective environment for its residents that constrains broader consideration of social sustainability. Through analysis of the marketing and presentation of specific domestic and other spaces of the eco‐city, we examine the application of ecologically modernizing construction and technology to the design of the city. We argue that the eco‐city is discursively constructed as ecologically beneficial for its inhabitants rather than for the broader socio‐environmental landscape. Our analysis of residential spaces in Tianjin eco‐city introduces the question of what ‘eco’ means when considering the construction of eco‐urban environments for the city's residents.  相似文献

Committed donors who keep giving every year are a key asset for nonprofit organizations because they provide a steady funding source and return a higher lifetime value. We distinguish between committed donors who give only one gift per year (single‐gift (SG) donors) and those who give multiple gifts in at least some year (multiple‐gift (MG) donors). In this paper, we study whether SG donors and MG donors follow different longitudinal patterns of gift‐giving in four consecutive years. We theorize that a donor's yearly gift amount is an indication of his or her willingness to give (WTG) to the organization and may be explained in terms of his or her intrinsic willingness to give (IWTG) and extrinsic willingness to give (EWTG) for that year. We test our theory with data from a leading US nonprofit organization and find that SG donors and MG donors would follow different longitudinal patterns:
  • While SG donors and MG donors would start off at a similar level of WTG in year 1 and would both increase WTG in subsequent years, MG donors would record a higher rate of increase than SG donors.
  • IWTG and EWTG would have different relative importance as determinants of the observed yearly giving level: MG donors depend on both IWTG and EWTG whereas SG donors largely depend on IWTG rather than EWTG to determine how much to give in a year.
Our findings suggest that different strategies are needed to manage SG donors and MG donors to sustain and grow annual contributions. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

Using data from the vehicle resale market, I test consumer responsiveness to large‐scale product recalls that are caused by safety problems. The used‐vehicle prices of Toyotas are compared to the used‐vehicle prices of the other major domestic and foreign manufacturers. The results quantify the losses suffered by Toyota vehicle owners in secondary markets due to the 2009–2010 safety recalls of more than 9 million Toyota Motors vehicles. The treatment effect of a recall is measured using panel data with a difference‐in‐differences estimation approach that allows for time‐varying treatment effects and serial correlation. I find that this recall episode had negative effects in the resale market for automobiles that were quantitatively small (less than 2% of the vehicle’s resale value), statistically indistinguishable from zero, and short lived (did not persist beyond December 2009). A comparison with Audi’s recalls in the 1980s of vehicles with sudden unintended acceleration suggests that the extent to which a company’s reputation is established is more important than whether or not a company has a reputation for producing high‐quality products.  相似文献

We explore the consequences for eligibility of members of subaltern groups for affirmative action (AA), when AA policies are based on social class criteria rather than on group affiliation (race, ethnicity, or gender), by means of a general model with simplifying assumptions. The model is developed first for the case where everyone eligible for AA becomes a beneficiary, and then for the case where beneficiaries are only those eligibles who are able to meet minimum qualification requirements for the positions at issue—an ability that is (reasonably) assumed to be correlated with socioeconomic status. The model demonstrates that class‐based affirmative action cannot provide as many subaltern‐group beneficiaries as group‐based affirmative action, especially when access to the desired positions hinges on performance qualifications. Data on AA‐targeted subaltern groups in rural India and in the United States are used to illustrate the conclusions of the model.  相似文献

Current research confirms the link between leadership behavior and subordinates’ health. However, only a few longitudinal surveys have been carried out. The present longitudinal study examined whether occupational self‐efficacy moderates the impact of transformational leadership on perceived negative well‐being. The sample consisted of 339 employees working in the health‐care sector. The correlations between transformational leadership at the first time of measurement (Time 1) and emotional exhaustion and perceived strain at the second time of measurement (Time 2) were negative and significant, but the correlation with depersonalization was not significant. Regression analyses revealed that the effect of transformational leadership behavior on perceived negative well‐being was not moderated by the level of occupational self‐efficacy. Implications for future research are discussed.  相似文献

Informal learning is an important source of employee adaptability and expertise, yet it is unclear how it may be encouraged through human resource management (HRM) practices. In this study, we investigate how opportunities for formal learning may be used to stimulate short‐ and long‐term participation in informal learning. In addition, we examine whether HRM system strength intensifies the relationship between opportunities for formal learning and informal learning. Using a sample of 430 respondents in 52 teams within six Dutch vocational and educational training schools, we adopt a longitudinal design to examine two types of autonomous informal learning activities (reflection and keeping up to date), and three collaborative activities (asking for feedback, knowledge sharing and innovative behavior) over two years. Opportunity for formal learning was positively related to short‐ and long‐term participation in informal learning activities, with the exception of long‐term innovation. Moreover, HRM system strength intensified these relationships. Managerial implications of these findings for encouraging informal learning activities at work are discussed. © 2016 Wiley Periodicals, Inc.  相似文献

  • The rise in global bond yields since mid‐April has taken markets by surprise. Our analysis suggests that, on balance, some upward correction in yields was justified – especially in the Eurozone. For the US, the evidence is more mixed.
  • A variety of explanations have been advanced to explain the bond sell‐off including Eurozone reflation/inflation, looming US rate hikes and associated uncertainty, liquidity and other technical factors, Chinese reflation and a simple reversal of yields overshooting to the downside.
  • Some of these explanations are more convincing than others: in our view there is some modest evidence for increased uncertainty and liquidity effects but we also think bonds have corrected from overbought levels, especially in the Eurozone.
  • Using some econometric models of bond yields suggests that the recent upward correction of German yields was probably justified; markets had pushed yields too low earlier in 2015. Indeed, the model implies a further ‘corrective’ rise in yields is possible.
  • For the US, different models give slightly different results – a variant of the well‐known Shiller‐Modigliani model suggests yields should still be below 2%. However, a broader error‐correction model including factors such as fiscal variables and foreign flows into US bonds suggests the recent rise in yields was broadly justified.

In today's high‐pressure work environment, project managers are often forced to “do more with less.” We argue that this imperative can lead project managers to engage in either high‐performance or abusive supervision behaviors. To understand this process, we develop a model and associated propositions linking a project manager's cognitive appraisal of project‐related demands to high‐performance work practices versus abusive supervision behaviors—both of which impact three project outcomes: stakeholder relationships, people‐related project success factors, and employee well‐being. We propose that the choice between high‐performance work practices and abusive supervision behaviors is moderated by a project manager's personal resources (psychological capital, emotional intelligence, and dark triad personality).  相似文献

In recent decades, co‐authorship and policies aimed at inducing academic collaboration have increased simultaneously. Assuming that intellectual collaboration is exogenously determined, prior studies found a negative relationship between co‐authorship and productivity. I examine a panel data on economists publishing from 1970 to 2011 to test the causal effect of intellectual collaboration on intellectual output. As characteristics of the individual and her opportunity set are endogenously related to both collaboration and productivity, I instrument the amount of co‐authorship by the common research interest between an author and her potential co‐authors. After controlling for endogenous co‐authorship formation, unobservable heterogeneity and time varying factors, the effect of intellectual collaboration on individual performance becomes positive.  相似文献

We study the relationship between diversification and firm performance in the context of the decline in levels of diversification over time. We argue that the pressure to reduce diversification may have more strongly affected those firms whose diversification strategies were most detrimental to firm performance. We employ meta‐analytical regression (MARA) in order to test our hypotheses, using a total of 267 primary studies containing 387 effect sizes based on 150,000 firm‐level observations from over 60 years of research on the diversification–firm performance relationship. The findings suggest that levels of unrelated diversification have decreased, whereas levels of related diversification have increased since the mid‐1990s, following an initial decrease in the 1970s and 1980s. Furthermore, we find that the relationship between unrelated diversification and firm performance has improved significantly over time, whereas the relationship between related diversification and performance has remained relatively stable.  相似文献

This paper outlines the economic reform process being undertaken in China and the subsequent partial closure and radical down-sizing of the state-owned enterprise sector. Redundancies arising out the restructuring process have eroded the state-worker contract of the iron rice-bowl. This has resulted in growing and sometimes violent labour unrest. The planned workforce projections until the end of the year 2000 suggest that the numbers of redundancies has increased, adding to China's 'surplus labour' problem. A critical issue is thus whether the Chinese government, together with state-enterprise management, can contain potential future labour and civil unrest using its present methods.  相似文献

I investigate whether the presence of customer‐oriented employees benefits firms in a competitive environment. Employees are defined as customer‐oriented if they are interested not only in their wage but also in the well‐being of their customers. I find that firms may obtain higher profits by hiring self‐interested rather than customer‐oriented employees. This is because the employees' customer orientation has opposing effects on the profits obtained by the firms. On the one hand, customer‐oriented employees provide a given level of quality for a lower wage. On the other hand, the employees' customer orientation increases competition reducing prices. If the second effect dominates, firms find themselves trapped in a prisoners' dilemma as the strategy of hiring self‐interested employees is strictly dominated by that of hiring customer‐oriented employees. Hence, the very presence of customer‐oriented employees may hurt firms. If motivated employees are merely interested in the quality of the good provided, the effect on the price outlined before disappears.  相似文献

Both senders and receivers derive benefits from telecommunications messages. Hence, consumers’ sending and receiving decisions generate external effects. We explore whether intercarrier compensation (i.e., an access charge) can induce carriers to set retail prices that internalize these external effects. We find that an access charge can induce constrained‐efficient sending and receiving prices for exchanging messages across networks, taking the sum of these prices as given, but cannot induce the correct sum. We also show that the internalizing role for the access charge can imply a nonzero access charge is efficient even in highly symmetrical situations, and that the efficient access charge may be positive or negative.  相似文献

Drawing on the relational perspective and self‐consistency theory, we theorize how relationships involving work‐centric, off‐work‐centric, and/or personal components can affect an employee's organization‐based self‐esteem and job performance in Chinese organizational contexts. Matched data were collected from a multi‐source sample that included 219 employee–supervisor dyads from a Chinese bank. Results based on hierarchical regression analyses reveal that a high‐quality relationship with a supervisor through work and off‐work domains (leader–member exchange and guanxi) is positively related to organization‐based self‐esteem. Organization‐based self‐esteem plays a mediating role in the relationship between guanxi and job performance. Additionally, career mentoring from a supervisor (a work‐centric relationship involving personal components) moderates the relationship between organization‐based self‐esteem and job performance.  相似文献

  • We have developed a new model to measure the impact on Eurozone equities of a global bond sell‐off as the Fed starts to tighten its monetary stance later this year. We show that the most affected countries would be Greece, Finland and Portugal: the cumulated equity loss compared to the baseline ranges from between 35% to more than 50% in the case of Greece at the end of 2017. Under this scenario, Belgium, Ireland and Austria are less impacted by the global re‐pricing of risk.
  • In light of global risk being skewed to the downside (China, Greece, risk‐off), it is essential to have a framework that is able to generate consistent responses of Eurozone stock indices to global macro shocks in stress test scenarios. The approach assesses first the co‐movements of Eurozone stock indices and aims to explain them with macro variables such as the US S&P index, the oil price, the euro/dollar exchange rate and short‐ and long‐term interest rate differentials between the Eurozone and the US.
  • We find a high degree of co‐movement in Eurozone equity returns. This matters from an asset management perspective, as it reveals limited potential for diversification benefits of an equity portfolio invested across Eurozone countries.
