The alternative Durbin-Watson test: An assessment of Durbin and Watson's choice of test statistic

This paper examines Durbin and Watson's (1950) choice of test statistic for their test of first- 0order autoregressive regression disturbances. Attention is focused on an alternative statistic, d'. Theoretical and empirical power properties of the d' test are compared with those of the Durbin-Watson test. The former is found to be locally best invariant while the latter is approximately locally best invariant. The d' test is also found to be more powerful than its counterpart against negative autocorrelation and for small values of the autocorrelation coefficient against positive autocorrelation. Selected bounds for significance points of d' are tabulated.     

The Economic Significance of User-Generated Feedback

This paper examines the impact of user-generated feedback on price at a price comparison site or shopbot. It employs a modified hedonic price function to explore the use made by current potential consumers of the experience of past actual consumers in evaluating quality attributes that were not observable when the product was initially launched on to the market. Using a database of daily observations on 211 digital cameras traded on NexTag.com, we find that the product’s star rating, reflecting all the available individual assessments of the product, has a significant negative impact on the discount on the manufacturer’s recommended selling price at which the product is offered.     

Toll-free numbers: Demand,property rights,and public policy

The demand for Toll Free Numbers (TFNs) languished from 2000 to 2008; however recent growth in demand caused the FCC to open a new toll-free code (855) with the possibility of new code openings in the next three years. The analysis here indicates the demand for TFNs is highly inelastic (the coefficient for own price elasticity for TFNs is approximately −0.04). This has implications for concerns regarding future exhaust of toll-free codes and the price structure for recovery of SMS/800's costs. This article considers the effects of the limited property rights for TFN, and welfare implications of gray markets for vanity TFNs. The FCC's allocation mechanism for new 855 codes is considered and whether other allocation mechanisms, such as auctions, could be welfare superior.     

Cost of Equity and S&P 500 Index Revisions

We examine how the cost of equity changes when firms are added to or removed from the S&P 500 Index during index revisions. Newly added firms experience a significant decline in the cost of equity, while recently removed firms show a significant increase. Liquidity improves for addition firms and declines for removed firms. Addition firms also experience a decline in shadow cost. Changes in cost of equity for included firms are explained by changes in liquidity, shadow cost, and firm size. Finally, included firms with greater investment opportunities benefit more from the reduction in cost of capital.     

Using the Delphi method to assess the potential of Taiwan's hot springs tourism sector

The purpose of the present study is to identify the various factors that influence the competitiveness of the hot springs tourism sector. The research draws on the models of Ritchie and Crouch, Dwyer and Kim, and Enright and Newton, who concluded that destination competitiveness is determined by three major components: resources and attractors, destination strategies and environments. The investigation produced both qualitative and quantitative data using the Delphi technique. An expert panel reached consensus about priorities for the development of Taiwan's hot springs tourism sector and provided written justifications for their responses. This paper reports on the qualitative findings of the three‐round Delphi survey and provides a supply‐side perspective on Taiwan's hot springs tourism sector. An examination of the expert comments concluded that the Taiwanese are increasingly concerned with good health and longevity. This emerging characteristic offers new business opportunities for the providers of hot springs tourism experiences to extend their appeal into health protection and medical treatments. However, if they are to achieve sustainable development and ensure high‐quality visitor experiences, hot springs proprietors will need to work closely with local governments and communities to promote sustainable use of natural hot springs and to conduct routine inspections of spa premises. Overall, the future of the hot springs tourism sector appears to be promising. Copyright © 2008 John Wiley and Sons, Ltd.     

A tactical retreat? Conceptualising the dynamics of European grocery retail divestment from East Asia

The internationalisation of the firm is a highly dynamic process, in which periods of investment and expansion intermingle with periods of divestment and retrenchment. Academic research to date has focused on identifying the reasons for and the processes of divestment. Empirical studies either evidence generic pressures or provide case studies of specific incidents. There few longitudinal studies of international divestment, consequently the dynamic interactions between host market, home market and firm level factors, and how the institutional context changes over time is underplayed. This paper seeks to rectify this gap in our understanding.We explore the rationale and evolving dynamics of European grocery retail divestment in East Asia over a thirty year period. Taking an inductive approach and drawing on analysis of contemporary narratives drawn from company documentation, trade journals, newsfeeds and market reports, three phases can be identified characterised by specific factors and combinations of factors which intersect to provide the key pressures and stimuli for divestment. We conclude that at different time periods, different internal and external contextual influences manifest themselves through different priorities within the firm’s strategy – marked by a switch from local (host) market, to regional, to global firm-centric considerations. Longitudinal analyses allow a greater recognition of this dynamic interplay of factors, and the changes in these relationships, and provides a more nuanced understanding of the international divestment process.     

Moral management in competitive markets

The intrinsic motivation of a firm’s management for engaging in prosocial behavior is an important determinant of a firm’s social conduct. I provide the first model in which firms run by morally motivated managers engage in corporate social responsibility (CSR) in a competitive setting. Moral management crowds out a competitor’s strategic CSR, increasing profitability and leading shareholders to strategically delegate moral managers, although necessary for socially optimal CSR is that shareholders be morally motivated as well. Shareholders appoint managers that engage in a socially excessive amount of CSR, counter to existing literature, whenever product‐market competition is sufficiently intense.     

Incentives and teacher effort

Few would contest that teachers are a very important determinant of how much students learn in school, and how to improve teacher performance has been the focus of lively policy debate in both rich and poor countries. This paper examines how teacher incentives, both pecuniary and non‐pecuniary, correlate with teacher effort. Using school survey data from Lao PDR, we estimate measures of teacher effort, including the number of hours that teachers spend preparing for classes and teacher provision of private tutoring outside of class hours, which are not the typical measures used in previous research. Estimation results fit well under the standard labour supply framework and indicate that greater teacher effort is associated with non‐pecuniary incentives such as more teacher autonomy over teaching materials and monitoring as measured by the existence of an active parent – teacher association and the ability of school principals to dismiss teachers. Methodologically, this paper provides a detailed derivation of a simultaneous OLS‐probit model with school random effects that can jointly estimate teacher work hours and tutoring provision.     

The Value of Online Seller Reputation: Evidence from a Price Comparison Site

This paper examines the value of seller reputation for e‐retailers trading via a price comparison site (PCS). E‐markets are widely held to accommodate sellers of differing service quality, including some who behave opportunistically. The paper uses a sample of offers on up to 295 digital cameras traded on a leading PCS, over a 134‐day period to estimate reputation's price impact. User‐generated reputation measures have a significant impact in the expected direction. However, their magnitude is small compared with variables capturing economy‐wide reputation. The strength of the reputation signal increased non‐monotonically with the number of reviews on which it was based. Copyright © 2015 John Wiley & Sons, Ltd.     

Common Method Variance in Advertising Research: When to Be Concerned and How to Control for It

In this article we discuss and analyze the critical issues related to common method variance (CMV) that are particularly relevant to advertising research and recommend best practices for assessing the effects of CMV in this domain. Specifically, we cover the development of CMV as a domain-specific methodological concern and the underlying sources of CMV that are likely to operate in cross-sectional survey-based studies in the field of advertising. We discuss in detail the available procedural and statistical techniques that can be applied to control for and/or measure the effects of sources of CMV in a single study and across research domains. In addition, we provide a critical look at how these techniques have been employed in past research and make recommendations for future examinations of CMV in advertising research.
