Nonparametric search

We analyze the search problem of a consumer who derives information only from the sequential search process. This paper considers the case of a consumer who uses a nonparametric procedure to estimate the probability distribution. It is shown that a solution to the consumer's problem is a very simple strategy which depends only on the order statistics, on the discounting factor, and on the duration of the search. It leads to a finite search almost surely. This optimal strategy is a myopic rule which is computable and which is characterized by a sequence of strictly increasing reservation prices.     

Gross substitution, Gresham's law, and Hayek's free currency system

Professor Hayek has advocated that citizens be free to use foreign currency as a means of payment in order to put a check on national governments' tendency to rely on the seigniorage for fiscal purposes. His proposed scheme is based on an intuitive reasoning that being able to use foreign currencies makes demand for domestic currency more elastic, thus reducing the monopoly power of national governments on currency issue. This paper demonstrates that this would be true if and only if the foreign currency were a gross substitute for the domestic currency. The paper also shows that the same condition holds for Gresham's law to be valid.     

Is per capita real GDP stationary in five southeastern European countries? Fourier unit root test

This study uses the newly developed Fourier unit root test advanced by Enders and Lee (2004, 2009) to investigate the time-series properties of real GDP (Gross Domestic Product) for five Southeastern European countries for the period from 1969 to 2009. The empirical results from several conventional unit root tests indicate that the per capita real GDP for all of the countries studied are non-stationary; however, when Enders and Lee (2004, 2009) Fourier unit root tests are conducted, one rejects the unit root hypothesis of real GDP per capita in all countries under study. These results have important policy implications for these five Southeastern European countries under study.     

The Corporate Governance Premium,Returns, and Mutual Funds

Mutual funds with a preference for strong corporate governance (CG) have performance similar to mutual funds with a preference for weak CG. We find a direct relation between overall mutual fund CG preference and the corporate governance premium (CGP). Furthermore, the investment preferences of mutual funds forecast the change in the CGP. We provide evidence that the investment activities of institutional investors can affect stock performance, and that shifts by institutional investors in CG preference impact the appearance of the CGP.     

The sources of bank productivity growth in China during 2002–2009: A disaggregation view

This study investigates the sources of bank productivity growth in China over the period 2002–2009. In order to perform this research, we propose an advanced index – input slack-based productivity index (ISP) – a model that disaggregates total factor productivity growth into each input productivity change. Funds, capital, and employees are chosen as the inputs, whereas loans and other earning assets are outputs in this study. Our results show that technological gains transcend the efficiency regressions and result in total factor productivity growth. More specifically, technical progress in capital productivity reveals the dominant force behind the total factor technical change and productivity improvement. In addition, this paper uses these disaggregation terms to find out the competitive advantages and disadvantages of input usages for each Chinese bank. These findings indicate that the ISP index provides more insights than traditional total factor productivity indices.     

The impacts of electronic commerce on auditing practices: an auditing process model for evidence collection and validation

The main purposes of this paper are twofold. First, the paper identifies and discusses the potential impacts of electronic commerce on auditing practices in the emerging paperless on-line transaction environment. Second, it provides two auditing process models that incorporate modern network security techniques and show how an audit can be conducted in an EC environment. A periodical auditing process model (PAPM) is proposed to demonstrate how secure electronic technologies can be used to facilitate the auditor's evidence collection and validation process for annual and semi-annual audits. We also present a continuous auditing process model (CAPM) which extends the functions of PAPM for continuous auditing. In CAPM, a real-time transaction monitoring system is used to link to firms' accounting information systems for assisting the auditor to detect abnormal activities and generate exception reports on a continuous basis. The CAPM approach intends not only to ensure integrity and effectiveness of the entire accounting system, but also to guarantee the correctness and usefulness of the constantly generated financial statements for public dissemination. The main contribution of this paper is that it illustrates a conceptual framework which shows the feasibility of continuously auditing electronic transactions in the EC environment.

Long-run underperformance following private equity placements: The role of growth opportunities

Our results show that the post-offering performance of private equity issuers is related to growth opportunities. We find significant long-run underperformance in stock returns following private placements only for firms with high Tobin's q. High-q firms experience not only poor stock price performance but also poor operating performance. Low-q firms, in contrast, do not display significant stock price or operating underperformance. We further examine three potential explanations for this relation: over-investment in assets by managers, investor skewness preference, and over-optimism about earnings prospects. Our results are consistent with the view that investors are overly optimistic about the prospects of high growth firms.     

An evaluation of influenza preventive measures on airlines: A passenger’s perspective

This paper examines influenza preventive measures on airlines based on a questionnaire survey of passengers at Taipei’s Taoyuan international airport. Quadrant scatter-plots of influenza preventive service attributes revealed that the clean cabin and disinfection services fell into the “Keep up the Good Work” quadrant; the personal protective requirements dimension in the “Low Priority” quadrant, and influenza preventive equipment dimension fell in the “Possible Overkill quadrant.”
