This paper considers stationary regression models with near-collinear regressors. Limit theory is developed for regression estimates and test statistics in cases where the signal matrix is nearly singular in finite samples and is asymptotically degenerate. Examples include models that involve evaporating trends in the regressors that arise in conditions such as growth convergence. Structural equation models are also considered and limit theory is derived for the corresponding instrumental variable (IV) estimator, Wald test statistic, and overidentification test when the regressors are endogenous. It is shown that near-singular designs of the type considered here are not completely fatal to least squares inference, but do inevitably involve size distortion except in special Gaussian cases. In the endogenous case, IV estimation is inconsistent and both the block Wald test and Sargan overidentification test are conservative, biasing these tests in favor of the null.

The purpose of this study is to explore possible factors leading to a successful mediation in Chinese mediation shows. In China, media always play an indispensable role in information dissemination, morality advocacy and policy explanation.
This paper employed content analysis of 166 episodes of one representative mediation show, Gold Medal Mediation, and regression technique in data analysis.
Results of ordinal regression suggested that “secret talking”, rather than transparency, between disputants had significant influence on successful mediation. Function of mediators is limited in reaching full mediation. The effective factors leading to full mediation include compromise of rights, secret talking, attitude of the observer cohort. It suggests that the role of mediator is limited, rather than being over-exaggerated, in successful mediation. The successful mediation is largely dependent on disputants’ motivations. Additionally, “compromise of rights” by disputants is a key factor in solving disputes.
Findings of this study revealed the role of Chinese mediation shows in propagating mediation in contemporary Chinese society and supporting upheld morality values. Due to the nature of the chosen mediation show, some disputes take more than one episode to solve. However, this study looks at each episode without considering the integrity of the dispute. That is, if the disputes take two episodes, the coder codes the two episodes as two separate disputes instead of looking at it as one dispute.
By exploring various aspects of mediations shows, including the role of mediators, disputants and a cohort of observers, this study can both explicitly show predicted factors to successful mediations on the shows, and can implicitly examine the power and perceived justification of mediation in contemporary China via media.
Economic theory suggests that profits of firms in industries with higher competition are less persistent and more volatile than in industries with lower competition (Stigler, 1963; Mueller, 1977). Extending this reasoning, I hypothesize that accounting-based fundamentals are more effective in predicting performance in industries with lower competition. I find that a measure of fundamentals (Piotroski’s F-score) has greater ability to identify potentially mispriced securities in industries with lower competition. The results are robust to using a variety of competition measures and imply that industry competition is an important consideration in the application of fundamental analysis.

The purpose of this paper is to suggest that the information ethics (IE) of students appear to improve more through adoption of the technology mediated learning (TML) platform rather than face-to-face (FTF) approach. In addition, it shows the pattern changes in each scenario resulting from the ethics training and analyses them from the Confucian ethics perspective, indicating that researchers should consider this aspect in future models.
This study employed non-parametric methods to test the outcome of the “information ethics course” of two kinds of training platforms. FTF training: 193 students; TML training: 185 students.
The TML platform produces a more significant improvement in the students’ respect for rules, privacy, accessibility, and intellectual property (IP) cognition, rather than the FTF method. Based on the findings, two propositions (eight sub-propositions) are formulated and revised two sub-propositions.
However, this study has a few limitations that can be enhanced by further research in the future: first, the data were only collected from one university (National Pingtung University), thus, the external validity is not satisfactory for all Chinese context students. Second, it is necessary to collect both of scenario-based and qualitative data from different cultural context students (such as Mainland China, the USA, Europe, Arabia, etc.) and then compare their results, thereby making further contributions to the current study. Third, the study was intentionally used as the measure of progress in ethical understanding without highlighting the difference between intentionality and actual behavior.
Teachers should draw upon the principles of Ren, Yi, and Li, from the Confucian ethics perspective to encourage students to respect the IE for Chinese context students. In addition, emphasis should be placed on the ability of students to build their information ethics cognition through the cognitive information processing learning methods, which can enhance the “accessibility,” “accuracy,” “privacy,” and “IP” cognition of Chinese students in both the FTF and TML platform learning process. This will help to reduce students’ unethical behavior as they advance in their future careers.

We study the events that motivate CEOs to underinvest in R&D long-term projects (CEO myopia). Based on the existing literature in earnings management and agency theory, myopia is likely to become more problematic under five circumstances: when the CEO nears retirement (the CEO horizon problem), R&D projects have very long time horizons (the project horizon problem), the firm’s financial health is deteriorating (the cover-up problem), ownership structure is heavily weighted toward insider owners (minority owner oppression problem), and when the threat of hostile takeover increases (the entrenchment problem). We setup a dynamic simulation model in which rational CEOs maximize the total value of their bonus compensation over their tenure. Our findings related to the five circumstances are consistent with the extant literature. However, we found an unexpected stable, nonlinear (inverted U-shaped) relationship between CEO tenure and R&D investment. We discuss the theoretical implications of our model and offer suggestions for future research.

This study provides new evidence on the effect of compulsory schooling laws on educational attainment and earnings. First, we re-examine the effect of compulsory schooling laws for cohorts born between 1900 and 1964 (“older cohorts”) using newly available data that match administrative earnings records with the survey data. Second, we provide among the first evidence on cohorts born between 1977 and 1996 (“younger cohorts”). Our findings suggest that compulsory schooling laws increased the educational attainment of older cohorts, but had no economically significant effect on the educational attainment of younger cohorts. We are unable to find consistent evidence that compulsory schooling laws increased the earnings of older cohorts – a finding which adds to growing evidence that compulsory schooling laws are less beneficial than earlier studies suggest.

We consider the Bayes estimation of a multivariate sample selection model with p pairs of selection and outcome variables. Each of the variables may be discrete or continuous with a parametric marginal distribution, and their dependence structure is modeled through a Gaussian copula function. Markov chain Monte Carlo methods are used to simulate from the posterior distribution of interest. The methods are illustrated in a simulation study and an application from transportation economics.

This paper aims to analyse whether the speed of Wi-Fi in hotels influences customer satisfaction with hotels and the implications of this for the provision of Wi-Fi by commercial and governmental bodies seeking to boost tourism.
Regression analysis on data from Australian hotels (191 entries) and 111 responses to a national survey of local government authorities on public Wi-Fi (PWF) provision were combined with a literature review and content analysis of online reviews by hotel customers.
If Wi-Fi quality rises by 1%, customer satisfaction with the hotel increases by 0.376/100 units. In the areas where hotel Wi-Fi is of better quality, PWF provided by the local government is also of better quality; the reverse statement is also true.
Tourists value continuous access to Wi-Fi, whether provided by commercial or public bodies. It is imperative for hotels and local governments seeking to boost tourist activity to invest in quality Wi-Fi networks. However, to assist this, national policies should address spatial disparities in broadband infrastructure revealed in the study.
This study looks beyond a conventional distinction between the private and public provision of Wi-Fi to examine the shared interests of industry and government in this essential component of tourist infrastructure. The study is unique in the English-speaking literature for its focus on the link between the quality of Wi-Fi provision and customer satisfaction, with original results and discussion providing a rationale for investing in quality Wi-Fi networks.
认真的么, 澳大利亚, 为什么你对WiFi 如此小气？：澳洲酒店顾客对Wi-Fi速度的满意度及其对公共Wi-Fi供给的启示
本研究分析了酒店的Wi-Fi 速度是否影响顾客满意度, 及其对致力于促进旅游业发展的商业和政府组织在提供Wi-Fi 服务上的启示
如果Wi-Fi质量提高百分之一, 顾客满意度会相应提高0.376/100个单位。在酒店Wi-Fi质量普遍较好的地区, 由地方政府提供的公用Wi-Fi也会有更佳质量, 反之亦然。
不管是商业还是公共组织提供的Wi-Fi, 游客都重视它的持续性使用。对那些想要发展旅游的酒店和地方政府来说, 加大对Wi-Fi 质量的投入是必要的。然而, 为了推进此举, 国家政策应该根据此项研究的结果解决宽带基础设施的地域差异问题。
本研究 超越了传统意义上的公共和私有供给Wi-Fi的区别, 从业界和政府机关共同利益的角度出发来对这项关键的旅游基础设施进行研究。本文对英文文献关于Wi-Fi质量和顾客满意度的关系提供了支持, 并且为提高Wi-Fi质量的理论依据提供了创新性结论和讨论。
“The Elephant in the Corner: A Cautionary Tale About Measurement Error in Treatment Effects Models” by Daniel L. Millimet discusses the current use of the unobserved-outcome framework to estimate population-averaged treatment effects, and it exposes the sensitivity of these estimators to assumption of no measurement error. The Monte Carlo simulation evidence in this chapter indicates that “nonclassical measurement error in the covariates, mean-reverting measurement error in the outcome, and simultaneous measurement errors in the outcome, treatment assignment, and covariates have a dramatic, adverse effect on the performance of the various estimators even with relatively small and infrequent errors” (Millimet article, p. 1–39). To some extent, all the estimators analyzed by Millimet are based on weak functional form assumptions and use semiparametric or nonparametric methods. Millimet's results indicate the need for measurement error models be they parametric or nonparametric models, see Schennach (2007), Hu and Schennach (2008), and Matzkin (2007) for some recent research in nonparametric approaches. Chapter 7 develops a Bayesian estimator that can handle some of the measurement errors discussed in this chapter.
