Keyword auctions with budget-constrained bidders

We study a keyword auction model where bidders have constrained budgets. In the absence of budget constraints, Edelman et al. (Am Econ Rev 97(1):242–259, 2007) and Varian (Int J Ind Organ 25(6):1163–1178, 2007) analyze “locally envy-free equilibrium” or “symmetric Nash equilibrium” bidding strategies in generalized second-price auctions. However, bidders often have to set their daily budgets when they participate in an auction; once a bidder’s payment reaches his budget, he drops out of the auction. This raises an important strategic issue that has been overlooked in the previous literature: Bidders may change their bids to inflict higher prices on their competitors because under generalized second-price, the per-click price paid by a bidder is the next highest bid. We provide budget thresholds under which equilibria analyzed in Edelman et al. (Am Econ Rev 97(1):242–259, 2007) and Varian (Int J Ind Organ 25(6):1163–1178, 2007) are sustained as “equilibria with budget constraints” in our setting. We then consider a simple environment with one position and two bidders and show that a search engine’s revenue with budget constraints may be larger than its revenue without budget constraints.     

Cross-listing effect of U.S. casino companies: Risk-adjusted performances

Globalization and market liberalization have resulted in more firms being listed on foreign stock exchanges. Even though cross-listing is an important corporate financial decision, research in this area for the hospitality discipline has been limited. The current study investigates issues of international cross-listing from the perspective of diversification. The findings from examination of five risk-adjusted measurements—Jensen's Alpha, Treynor Index, Sharpe Ratio, Sortino Ratio, and Upside Potential Ratio—for U.S. casino companies show that cross-listing improves U.S. casinos’ performances in terms of Jensen's Alpha and Sharpe Ratio, but not in terms of the other three measures.     

Impact of brand recognition and brand reputation on firm performance: U.S.-based multinational restaurant companies’ perspective

Given the importance of a firm's performance, which is of significant interest to many groups of people including management, shareholders and governments, this study aims to examine the impact of brand recognition and brand reputation on firm performance within the U.S. multinational restaurant company context. The study findings suggest that brand reputation, in general, has a positive influence on a firm's value performance but no significant relationship with accounting performance. Brand recognition shows no significant relationship with both value and accounting performance measures controlling for the degree of internationalization of a multinational restaurant company.     

The Effect of Audit Partner Diversity on Audit Quality: Evidence from China

This study examines the effects of audit partner diversity on audit quality. Using a sample of Chinese listed companies from 2004–2018, we find that audit quality is positively associated with audit partner diversity in educational background, gender, and generational cohort. These findings suggest that diverse partner teams outperform homogenous teams and support the information perspective that audit partner diversity produces different viewpoints and perspectives, thus reducing judgement bias and leading to higher audit quality. Furthermore, we find that client information asymmetry, auditor task motivation, and task ability play a moderating role in reinforcing the positive effects of audit partner diversity on audit quality. Our findings have practical implications for audit firm personnel dispatching and team formation, and heighten the need to integrate team dynamics in the audit quality framework.     

New sustainable business models in China

This research explores the need to establish new sustainable business models in China and uses multiple objectives to examine in a sample of Chinese companies the reality of the level of sustainable development, environmental awareness and performance, community responsibility, performance barriers and drivers and other sustainability issues. A mixed methodology was adopted, using a questionnaire survey and interviews with 20 manufacturing companies in Guangzhou and Shenzen. Evidence from the small sample of companies demonstrates the lack of significant sustainable development practices in China, although small and medium sized companies appeared to show interest in this area and would like to further contribute to for example triple bottom line objectives. Increasing concerns are found from the company level regarding the need to use renewable energy, source alternative sustainable materials, close the loop of the supply chain, improve the quality of products produced rather than reducing cost, export to Europe and treat employees as an asset. The lack of skills, finance and knowledge are found to be prohibiting the effective embedment of sustainable development within companies and hence cause an under‐performance in this regard. The study concludes that the establishing of a new business model for sustainable development in China is needed urgently, and this should be a joint effort with the Chinese government.

A functional approach for studying technological progress: Application to information technology

This paper develops and assesses a broad functional category approach to arriving at metrics for assessing technological progress. The approach is applied to three functional categories of information technology — storage, transportation and transformation by first building a 100 plus year database for each of the three functional categories. The results indicate generally continuous progress for each functional category independent of the specific underlying technological artifacts dominating at different times. Thus, the empirical results reported in this study indicate that the functional category approach offers a more stable and reliable methodology for assessing longer time technological progress trends. Therefore, this approach offers the promise of being more useful in technological forecasting for large-scale change even as its ability to forecast specific dominant technological trajectories has been compromised.     

Auctions for transferable objects: Theory and evidence from the vehicle quota system in Singapore

This paper studies the hypothesis that auctions with resale markets result in higher prices. The vehicle quota system introduced in Singapore in May 1990 provides the setting. The Certificates of Entitlement (COEs) necessary to purchase new cars were initially transferable for all quota categories. After October 1991, COEs for four major categories became non-transferable. Our results indicate that while the conversion to non-transferability eliminated speculation, it has also intensified competition among car distributors. Auctions for non-transferable COEs in fact led to higher COE prices in three of the four categories.An earlier version of this paper was presented at the Symposium on Law and the Social Sciences, 7 August 1992, at the Regional English Language Centre, Singapore.
