A sequential selectivity model of the decisions of arbitrators

The study investigates arbitrator gender and grievant gender effects on the decisions of 146 arbitrators rendered on a hypothetical drug-testing case. The effects are estimated using a sequential selectivity model. This approach takes into account the sequential and conditional nature of arbitrators' decisions. The results indicate that arbitrators are more likely to overturn terminations when the grievant is female, and that female arbitrators are less likely to fully reinstate grievants when the termination is overturned. Other results include the finding that older arbitrators treated grievants more harshly by more often awarding only partial reinstatements. When suspensions are given, however, we find that older arbitrators award shorter suspensions than do younger arbitrators. It is also found that more experienced arbitrators awarded longer suspensions than less experienced arbitrators.     

The South African Financial Cycle and its Relation to Household Deleveraging

This paper considers the extent to which South African households have deleveraged, since the global financial crisis of 2007/2008. We extend the official South African Reserve Bank business cycle methodology to date financial cycles, from which we identify the peaks and troughs of the South African financial cycle going back to 1966. Our composite financial cycle index peaks in April 1974, January 1984 and May 2007; it has bottomed out in July 1979 and February 1999. Thus, we still await the trough. We further compare and contrast the deleveraging process in the current downward phase to the experiences from previous financial cycles. We find that the average period of the financial cycle in South Africa is much longer (approximately 17.3 years) than that of the business cycle (approximately 5.8 years), and that deleveraging has not yet matched the degree of deleveraging seen in previous downward phases. Our results suggest that further deleveraging is necessary, before we can expect to turn the financial corner.

Is it still economic to build a new coal-fired power plant in the U.S.? A real option analysis

In the U.S., virtually no new coal-fired power plants have been built in recent years. Both industry experts and academics seem to believe that no rational firm will build a new coal-fired plant. Will such a trend continue in the future? To provide insights into this question, we investigate the optimal decision of an electricity company with an irreversible and deferrable opportunity to build either a new coal-fired or natural gas-fired power plant as its new base-load resource. According to our real option analysis, the optimal decision depends on the location. In the case of the eastern U.S., it is optimal to choose a natural gas plant if a firm is given a choice among a new natural gas plant, a new coal plant and deferring the investment. However, contrary to the common sentiment in the industry and academia, building a new coal plant in the western U.S. is still more economical than building a new natural gas plant in the absence of emission pricing. Furthermore, introducing carbon pricing to western U.S. states, as California did, can substantially increase the probability that a firm will optimally choose a natural gas plant over a coal plant.     

Critical representations of Southern African inequality: Transcending outmoded exhibition and museum politics

ABSTRACT

Illustrating inequality to a more general public – beyond those concerned purely with public policy and research – presents various challenges. Museums have often served a function of memorialising both the impressive steps forward and major barriers to social progress, as a form of remembrance and understanding, although the twentieth century format in South Africa was generally embedded within colonial and racist self-glorification. The potential to transcend outmoded exhibition and museum politics with a new approach based on dialogical not didactic presentation, arises with inequality. In this exploration of how such an approach might unfold in the world's most unequal major city (as judged by the Palma Ratio), Johannesburg, the concept of threshold is introduced. Physical and conceptual access through overcoming thresholds is explored through a specific site, the Old Post Office, and through two artifacts that reveal structural power that generates inequality: Durban's sanitation system and Eastern Zimbabwe's diamond fields.     

Buying reputation as a signal of quality: Evidence from an online marketplace

Seller reputation, generated by buyer feedback, is critical to fostering trust in online marketplaces. Marketplaces or sellers may choose to compensate buyers for providing feedback. Signaling theory predicts that only sellers of high-quality products will reward buyers for truthful feedback, especially when a product lacks any feedback and when the seller is not established. We confirm these hypotheses using Taobao's reward-for-feedback mechanism. High-quality products, especially without established feedback, are chosen for feedback rewards, which cause sales to increase by 36%. Marketplaces and consumers can therefore benefit from allowing sellers to buy feedback and signal their high-quality products in the process.     

The robustness of the independent private value model in Bayesian mechanism design

Summary. In a Bayesian model of group decision-making, dependence among the agents' types has been shown to have a beneficial effect on the design of incentive compatible mechanisms that achieve the efficient choice associated with complete information. This effect is shown here to depend as much upon the use of large monetary transfers among the agents as it does upon dependence: if the transfers are bounded in magnitude, then nonexistence in the case of independence of an efficient, incentive compatible, ex ante budget-balanced and interim individually rational mechanism is robust to the introduction of a small amount of dependence among types. This robustness result supports the use of the simplifying assumption of independence in mechanism design. Received: October 28, 1996; revised version: May 28, 1997     

Role of the Internet Site in the Promotion Management of Sports Teams and Franchise Brands

This study examines the role that a website plays in the development of fan allegiance and as a promotion management tool for a sports team and brand. Research indicates that the combination of sports, media (television in particular), and sponsorships when employed in an integrated manner, can develop consumer connection to brands. This study suggests that the Internet is also an important part of an integration strategy of sports, media, and promotion. By working with a new team in the AIFA indoor football league, the researchers were able to determine what helped make fans allegiant to the team before the franchise's inaugural game. The results show that even before the team played its inaugural home contest, fans had become allegiant to the franchise brand and team by using the team internet site. These results indicate that an internet site can serve as a strong promotional tool in an integrated marketing plan of sports, media, and promotion to move fans toward brand loyalty and toward primary goals of the firm, including increased sales.
