In 2008, Industry Canada auctioned 105 MHz of spectrum to a group of bidders that included incumbents and potential new entrants into the Canadian mobile phone market, raising $4.25 billion. In an effort to promote new entry, 40 MHz of spectrum was set‐aside for new entrants. In order to estimate the implicit cost of the set‐aside provision, we estimate the parameters of the bidders' profit function via a maximum match estimator based on the notion of pairwise stability in matches. We find that all telecommunications firms valued both geographic complementarities across auction licenses as well as absolute spectrum. Under a reasonable alternative scenario, our results indicate that the set‐aside led to a total profit loss of approximately 10%. 相似文献

NONPARAMETRIC AUTOCOVARIANCE FUNCTION ESTIMATION 总被引:2,自引:0,他引:2
Nonparametric estimators of autocovariance functions for non-stationary time series are developed. The estimators are based on straightforward nonparametric mean function estimation ideas and allow use of any linear smoother (e.g. smoothing spline, local polynomial). The paper studies the properties of the estimators, and illustrates their usefulness through application to some meteorological and seismic time series. 相似文献

Perceived organizational support (POS) is viewed as an important explanatory framework for understanding the relationship between employees and the workplace, and is regarded by some researchers as central in understanding job-related attitudes and behaviors of employees. However, less research has taken into account the role of organizational identification, which reflects how individuals define the self with respect to their organization, as a potential influence on such relationships. Drawing on a cross-organizational sample of 238 subordinate-supervisor dyads from the People’s Republic of China, we examined whether organizational identification mediates the effect of perceived organizational support (POS) on work outcomes including turnover intentions, work performance, and organizational citizenship behavior (OCB). Results from the current study showed that organizational identification fully mediates the relation of POS to OCB-directed to individuals, and partially mediates relations between POS and other work outcomes (turnover intention, work performance, OCB-directed to organization). Implications for management theory and practice are discussed. 相似文献

The purpose of this qualitative study was to explore how newly married couples construct and reconstruct commitment through events in courtship and early marriage. Fifteen newly married couples, 30 participants, were interviewed individually. Through the use of grounded theory six different themes (friendship, gradual process, positive examples, negative examples, planning for the future, and words of affirmation) emerged in the construction, origination, and communication of commitment. The results of this study have specific implications for theory, research, and practice with young adult couples. The concept of resilient commitment is introduced and briefly discussed. 相似文献

AbstractVideo game culture has a long, ongoing history of problems with representation and inclusivity, as a wide variety of forces have constructed video games and gaming as masculine. Against this background, the popular gamer-oriented web series The Guild (2007–2013) appears to offer a unique counterperspective, presenting a gender-diverse cast and focusing primarily on female protagonist Cyd “Codex” Sherman. As such, the show could potentially diversify popular conceptions of gamers. Through a close reading of The Guild, however, we demonstrate that it fails to do so. More specifically, the show’s portrayal of gamer identity serves as a form of cruel optimism, presenting it as an ideal that promises game players a consistent subculture and a sense of belonging, but ultimately traps them in narrow roles and identity constructs. Furthermore, the show’s gamer ideal also reproduces particular forms of gendered inequalities that posit aggressive, competitive masculinity as superior to both more passive masculinities and all forms of femininity. Overall, this leads The Guild to reinforce gaming culture’s existing problems with sexism and regressive stereotypes. Because of this, the show presents a relation of cruel optimism, assuming the appearance of positive change while failing to deliver on it. 相似文献

In the housing unit method, population is calculated as the number of households times the average number of persons per household (PPH), plus the population residing in group quarters facilities. Estimates of households and the group quarters population can be derived directly from concurrent data series, but estimates of PPH have traditionally been based on previous values or estimates for larger areas. In our study, we developed several regression models in which PPH estimates were based on symptomatic indicators of PPH change. We tested these estimates using county-level data in four states and found them to be more precise and less biased than estimates based on more commonly used methods. 相似文献

In this article, we study behavior in a series of two‐player supply chain game experiments. Each player simultaneously chooses a capacity before demand is realized, and sales are given by the minimum of realized demand and chosen capacities. We focus on the differences in behavior under fixed pairs and random rematching. Intuition suggests that long‐run relations should lead to more profitable outcomes. However, our results go against this intuition. While subjects' capacity choices are better aligned (i.e., closer together) under fixed pairs, average profits are more variable. Moreover, learning is slower under fixed pairs—so much so that over the last five periods, average profits are actually higher under random rematching. The underlying cause for this finding appears to be a “first‐impressions” bias, present only under fixed matching, in which the greater the misalignment in initial choices, the lower are average profits. 相似文献
