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 equivalence of supporting software delegation and sales delegation

This paper considers a duopoly market with horizontally differentiated system goods to examine system owners' behaviors under supporting software delegation, in which owners of system firms use varieties of supporting software, coupled with profit, to evaluate their managers' performance. Supporting software delegation seems to induce managers to act more aggressively in price competition than sales delegation does; however, we prove that if two systems are compatible and the varieties of supporting software are determined by hardware owners' overall expenditure amount on software, then supporting software delegation is equivalent to sales delegation. Owners of system firms induce their managers to act less aggressively in hardware price competition by offering contracts with a negative weight on varieties of supporting software under supporting software delegation. We find that stronger network externalities do not reverse system owners' contracting behaviors under supporting software delegation. Finally, it is worth mentioning that hardware technologies are static in this paper. In other words, dynamic changes such as hardware evolution are not considered in our analysis.     

The non-linear impact of oil price on the oil demand

ABSTRACT

A panel smooth transition regression model was adopted to analyse the non-linear impact of oil prices on oil demand. Data for 42 countries was obtained from the International Energy Agency for the time period spanning from January 1990 to June 2017. The results indicate that a threshold value does exist. Furthermore, when the oil price was lower than this threshold value, a positive relationship between oil price and oil demand was observed. When the price of oil was higher than the threshold value, however, a negative relationship between price and demand was found.     

Audit Partner Disciplinary Actions and Financial Restatements

This study investigates the signalling role and rectification effectiveness of an audit partner disciplinary system. The signalling role refers to whether sanctions reflect the poor audit quality of disciplined audit partners, and rectification effectiveness addresses whether disciplinary actions enhance subsequent audit quality. The sample consists of Taiwanese listed companies, in the period 2000 to 2006, where the identities of audit partners who sign audit reports and who are sanctioned are accessible. Empirical results indicate that in the pre‐sanction period, the probability of financial restatements by clients of disciplined audit partners is significantly higher than that of non‐disciplined audit partners. The more severe or frequent the sanctions, the higher the likelihood of financial restatements in the pre‐sanction period. These findings imply that audit partner disciplinary actions can serve as a signal of lower audit quality provided by those partners. The rectification effectiveness of disciplinary actions is examined from two perspectives: (1) the effects on subsequent improvements of audit quality of disciplined audit partners; and (2) audit quality enhancement of successor non‐disciplined audit partners who accept clients from disciplined audit partners. Empirical results show a lower probability of restating financial statements audited by disciplined audit partners after sanctions. We also find a lower likelihood of restating financial statements audited by successor non‐disciplined audit partners in the post‐sanction period. Both findings support our conclusion that audit partner sanctions improve audit quality. Overall, audit partner disciplinary actions can signal lower quality audit partners and are effective in enhancing audit quality.     

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.     

Better peers,better scores? A study of twin junior high school graduates in Taiwan

Using data of twin students graduating from junior high schools between 2002 and 2004 in Taiwan, we estimate the effects of peers on high school joint entrance examination performance. To alleviate the potential endogeneity of peer educational achievement, linear models with twin fixed effect and instrumental variables are estimated. Quantile, quantile with twin fixed effect and quantile with instrument variables regressions are also implemented to determine whether estimated peer effects differ at various locations of the testing scores’ conditional distributions. Positive and statistically significant peer effects are found to exist at the mean and at different quantile levels.
