Product Differentiation through Exclusivity: Is there a One‐Market‐Power‐Rent Theorem?

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.     

‘Eco’ For Whom? Envisioning Eco‐urbanism in the Sino‐Singapore Tianjin Eco‐city,China

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.     

Are single‐gift committed donors different from their multiple‐gift counterparts?

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.     

Sudden Unintended Used‐Price Deceleration? The 2009–2010 Toyota Recalls

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.     

Who Is Eligible? Should Affirmative Action be Group‐ or Class‐Based?

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.     

Who Will We Recruit? Targeting Deep‐ and Surface‐Level Diversity with Human Resource Policy Advertising

Research on targeted recruitment has focused on targeting applicants with surface‐level attributes such as underrepresented demographic groups. The present study extends targeted recruitment research by examining how advertising human resource policies might be useful for targeting both surface‐ and deep‐level attributes. Specifically, the current study uses an experimental design to examine the impact of work‐family, diversity, and employee development policies on the job‐pursuit intentions of working adults in the United States. We examined surface‐ (demographic characteristics; e.g., race) and deep‐level differences (attitudes or values; e.g., diversity values) as predictors of whether participants intend to pursue jobs with firms advertising these human resource (HR) policies. Deep‐level differences consistently predicted job‐pursuit intentions for all three HR policies, but only marginal support was obtained for surface‐level variables as predictors. Findings suggest that targeted recruitment based on deep‐level attributes may be more successful than targeted recruitment based on surface‐level factors.     

The Relation Between Leadership and Perceived Well‐Being: What Role Does Occupational Self‐Efficacy Play?

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.     

Do Opportunities for Formal Learning Stimulate Follow‐Up Participation in Informal Learning? A Three‐Wave Study

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.

The global bond sell‐off – why and where next?

• 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.

     

Old Wine in Private Equity Bottles? The Resurgence of Contract‐for‐Deed Home Sales in US Urban Neighborhoods

This article describes the reemergence, in the wake of the mortgage crisis, of a predatory financial practice in predominantly black neighborhoods in the US: the contract for deed (CFD). The CFD has a notorious urban history; it was a focus of social justice organizing in 1960s Chicago, which helped lay the groundwork for advocacy that culminated in two important laws in the US: the Home Mortgage Disclosure Act of 1975 and the Community Reinvestment Act of 1977. This article places the reemergence of the CFD in the post‐crisis cycle of housing investment and disinvestment, estimates the minimum scale of CFD ownership, and examines the geography of a well‐known CFD seller in the Atlanta area. As policymakers in the US took efforts to restrict predatory lending fueled by private‐label securitization following the subprime crisis, capital markets shifted toward private equity financiers who provided a new supply of lightly regulated capital for urban housing markets. Predominantly black neighborhoods became prey for high‐return schemes meant to extract as much cash flow out of vulnerable residents as possible, offering them the illusion of homeownership. The findings show that the CFD seller focused on black neighborhoods and suggests that its profits from this activity have been quite lucrative.     

Do LGBT‐supportive corporate policies enhance firm performance?

Prior research provides evidence that lesbian, gay, bisexual, and transgender (LGBT)‐supportive corporate policies are related to important human resource functions, such as enhanced recruitment and retention. In addition, prior research indicates that investors view the adoption of such policies positively. We examine the firm‐performance mechanisms underlying favorable stock‐market reactions based on an integration of perspectives from corporate social responsibility and the business case for diversity. Specifically, we estimate a hierarchical linear model (HLM) to account for the nested nature of our data (firms nested within states) and find that (1) the presence of LGBT‐supportive policies is associated with higher firm value, productivity, and profitability; (2) the firm‐value and profitability benefits associated with LGBT‐supportive policies are larger for companies engaged in research and development (R&D) activities; and (3) the firm‐value and profitability benefits of LGBT‐supportive policies persist in the presence of state antidiscrimination laws. In supplemental analyses, we find that firms implementing (discontinuing) LGBT‐supportive policies experience increases (decreases) in firm value, productivity, and profitability. We are among the first to link LGBT‐supportive policies specifically to financial performance outcomes as well as to develop and test a multilevel model of these relationships. Our results have important implications for theory and research on LGBT issues in organizations, human resource managers, and policymakers.     

Rallying the Troops or Beating the Horses? How Project‐Related Demands Can Lead to Either High‐Performance or Abusive Supervision

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).     

Does Co‐authorship Lead to Higher Academic Productivity?

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.     

Does the Diversification–Firm Performance Relationship Change Over Time? A Meta‐Analytical Review

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.     

Customer‐oriented employees: Blessing or curse for firms?

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.     

Could unemployment go back to the post‐war heyday?

• ? The current ‘low’ rate of unemployment looks less impressive when compared with the 2–3% rates averaged in the 1950s and 1960s. But both then and now share a common driver of low joblessness – pay growth falling unusually short of productivity gains. While the chances of this continuing look stretching, a return to genuine full employment is not completely implausible .
• ? Why was unemployment so low in the early post‐war period? Given the current uncertainty over how far joblessness can sustainably drop and how this affects monetary policy, our analysis provides useful insights for the situation today.
• ? Several explanations have been mooted. A political commitment to full employment is one, although aspiration alone cannot provide a cause. And demand management using fiscal policy is hard to square with the period's modest budget deficits. Meanwhile, booming post‐war investment and trade and shortages of labour fail to explain why low joblessness did not quickly trigger rapid rises in pay and inflation.
• ? The cause of very low unemployment appears to have sat with wage restraint relative to productivity gains. Unlike most of the last 70 years, real pay growth consistently fell short of productivity rises in the 1950s and part of the 1960s, cutting the cost of workers and ensuring a low ‘equilibrium’ rate of unemployment.
• ? This explanation has parallels with the present day. Since 2010, productivity growth has outstripped real pay rises to an extent not seen since the 1950s. We do not expect this pattern to continue – our forecasts show real pay running slightly ahead of productivity growth over the next five years. But if the factors holding back pay were to persist, alongside a catch‐up in UK productivity, a return to a 1950s/60s‐style jobless rate is possible, if the MPC did not take fright at further declines in unemployment.
