Mobile Commerce Competitive Advantage: A Quantitative Study of Variables that Predict M-Commerce Purchase Intentions

Seeking to fill a gap in current research on the conditions that would facilitate user acceptance of m-commerce, the present study investigated m-commerce users’ perceptions of performance and effort expectancies, social influence, and facilitating conditions of m-commerce trust and perceived risk. We also analyzed how these aspects affect m-commerce purchase intentions. To this end, a total of 165 adult American users of m-commerce were surveyed and their perceptions of performance and effort expectancies, social influence, facilitating conditions of m commerce trust and perceived risk, as well as their m-commerce purchase intentions, were measured. Performance and effort expectancies, social influence, as well as the facilitating conditions of trust in the use of m-commerce, were found to significantly predict m-commerce purchase intentions. The findings also provided further clarification of the facilitating conditions of m-commerce purchases suggesting that implicit motivations and approach oriented goals might be significantly associated with m-commerce purchase intentions.     

Land-use change in the ‘edgelands’: Policies and pressures in London's rural–urban fringe

Green Belt policies have helped to create chaotic landscapes at the rural–urban interfaces of the United Kingdom's largest cities. Their prime functions, to control urban sprawl and preserve an encircling green girdle to separate the urban from the open countryside, have created ‘edgelands’ that have been remarkably dynamic despite relatively strong controls on certain types of development. A detailed case study of one part of London's Metropolitan Green Belt, drawing upon analysis of planning registers, reveals long-term trends in land-use change linked to the development controls operated within the context of the Green Belt and the adjacent built-up area. This paper also outlines the history of the Green Belt policy in the United Kingdom (UK) and discusses recently proposed policy changes that have provoked ongoing debate about this form of control on urban sprawl and its consequences for the land use of Green Belts and the edgelands.

The surplus prior to ruin and the deficit at ruin for a correlated risk process

This paper presents an explicit characterization for the joint probability density function of the surplus immediately prior to ruin and the deficit at ruin for a general risk process, which includes the Sparre-Andersen risk model with phase-type inter-claim times and claim sizes. The model can also accommodate a Markovian arrival process which enables claim sizes to be correlated with the inter-claim times. The marginal density function of the surplus immediately prior to ruin is specifically considered. Several numerical examples are presented to illustrate the application of this result.     

Absorbing knowledge in the digital age: the key role of integration mechanisms in the context of crowdsourcing for innovation

The digital age offers unprecedented opportunities for firms to access new knowledge for innovation. Both academics and managers have identified crowdsourcing (CS) as one relevant way to do so. CS for innovation involves outsourcing problem-solving or creative tasks to the crowd. To benefit from CS, absorptive capacity (ACAP) is critical; this can be enhanced by prior knowledge and past experience with a partner. However, in the CS context, firms open themselves up to undefined, anonymous partners through the Internet, hence the development of ACAP becomes more difficult. The literature on ACAP describes how internal integration mechanisms encourage the absorption of knowledge but fails to clearly address the way in which uncommon knowledge is integrated. Although literature has acknowledged the beneficial role of a wider spectrum of influential internal and external mechanisms on uncommon knowledge, few empirical studies have addressed the distinctive effect of these mechanisms on the absorption of anonymous partners’ knowledge. To fill this gap, this study identifies relevant integration mechanisms and how they impact upon different ACAP dimensions in the CS context. Five case studies reveal the distinctive influence of integration mechanisms depending on the nature of the CS activity. Our results extend research on ACAP in the little studied digital open context, investigating the absorption of uncommon knowledge from unidentified partners. From a managerial perspective, this study shows that managers need to pay attention to integration mechanisms in order to support the absorption of knowledge from the crowd. More precisely, our study suggests that the main focus should not be on external mechanisms, but also on internal mechanisms. Finally, we open up a new theoretical debate on how these mechanisms should be combined.     

The holiday and Yom Kippur War sentiment effects: the Tel Aviv Stock Exchange (TASE)

Several empirical studies reveal that holidays generally create positive sentiment in the stock market, whereas negative events, such as wars or disasters, are accompanied by negative sentiment. However, what happens if a negative event occurs on a holiday? In such a case, we expect two conflicting sentiment effects, which may cancel one another out or, alternatively, one effect may dominate the other. The stock market in Israel provides a unique laboratory in which to test these two conflicting effects, as Israel faced a horrible war on the Yom Kippur holiday in 1973—a war whose influence is still strongly felt today. Indeed, we find two robust effects: A strong and significant positive holiday sentiment effect; and a negative war sentiment effect, which dominates the positive holiday effect. These results, which show how sentiment effects are created, are general and can easily be applied to other events and other markets when conflicting sentiment effects occur.     

A note on perceptions of auditors’ internal control report mandated by the PCAOB: Can reformatting the report enhance perceived value added?

The auditor’s report is a critical link in communicating financial data to users. Because of substantial audit costs incurred in integrated audits, the perceived value added by the auditor’s report becomes even more important. The auditor’s report prescribed by Auditing Standard No. 2 (and the new Auditing Standard No. 5) issued by the Public Company Accounting Oversight Board (PCAOB) includes a limitations paragraph. The SAS 58 audit report format that has been in use over 15 years does not contain a limitations paragraph. The SAS 58 report likely serves as a mental frame of reference (a referent report) for users evaluating other independent auditor’s report formats relating to assurance services, including the AS2 and AS5 reports. Whether inclusion of a limitations paragraph could adversely affect the users’ evaluation of the AS2 report is the focus of this study. In light of the publicity given to fraudulent financial reporting and other prevailing economic/environmental conditions, it is reasonable for users to expect that the auditor’s report provide a high degree of assurance regarding material fraud.We extend the [Foster, B. P., McClain, G., Shastri, T. (2005). A note on Pre-Sarbanes-Oxley Act users’ and auditors’ perceptions of a limitations paragraph in the auditor’s internal control report. Research in Accounting Regulations, 18, 195-217] study, by focusing on the AS2 report using data obtained about user perceptions from a field experiment conducted with MBA students. Results suggest that users perceive that an internal control report format without the limitations paragraph will enhance the readability and reliability of the report, and reduce the level of accommodation (additional information) required for decision making. Users perceive that the auditors’ exposure/liability is likely to remain substantially the same whether or not the report format includes a limitations paragraph. Also, users perceive that incorporating fraud wording would further enhance the readability and reliability dimensions of the internal control report format without the limitations paragraph. Taken collectively, the auditor’s report format with fraud wording, but without the limitations paragraph likely maximizes economic benefit accruing to users by minimizing their information risk. Policy-making bodies may find the results and approach taken in this study useful to evaluate report formats for assurance services.     

The Political Economy of Chinese-Style Privatization: Motives and Constraints

The paper examines how the privatization of Chinese state-owned enterprises (SOEs) can be successfully triggered and completed. By identifying the motives of local government leaders and the constraints that face them during transition, we conclude that: first, whether local governments are motivated to privatize their SOEs, depends on if the ownership transfer is expected to stimulate sufficiently high growth of local tax revenues without sacrificing the bureaucrats private control benefits. Second, a specific privatization program can succeed only if it manages to satisfy the managerial cooperation constraint, the workers compensation constraint, and the bank-debt-servicing constraint. The motives-cum-constraints political economy approach offers an important explanation for the pace and scope of the ongoing Chinese-style privatization.
