Unionization is generally thought to improve employee welfare through higher compensation and benefits. However, managers of unionized firms have incentives to manage earnings downward to avoid sharing rents with unionized workers, which may explain why empirical findings on the association between unionization and employee compensation are mixed. This paper develops an analytical model incorporating earnings management into the relationship between newly unionized firms and employee compensation.

The authors develop an analytical model that relies on Nash bargaining theory and signal jamming (Stein, 1989; Fischer and Verrecchia, 2000; Dye and Sridhar, 2004) and model a setting where newly unionized workers' collective bargaining power increases substantially. The authors' model analyzes the relationship between newly unionized firms and employee wages and benefits while incorporating firms' incentives to engage in earnings management.

The authors find that newly unionized firms are more likely to engage in income-decreasing earnings management to avoid paying higher salaries and wages to workers. Further, the authors find that this association is more pronounced when (1) the correlation of firms' earnings across periods is higher, (2) the cost of earnings management is lower and (3) firms' earnings are more volatile.

This is the first paper to analytically model the effect of new unionization on firms' earnings management and workers' welfare. The authors' model offers new cross-sectional predictions that have not been tested in the prior literature. Specifically, the authors show that newly unionized firms are more likely to engage in income-decreasing earnings management; when earnings are more highly correlated, the cost of earnings management is lower and earnings are more volatile. The authors' findings may be relevant to regulators and policymakers.

The purpose of this paper is twofold: to develop the college-attendance value scale (CAVS) in the Taiwan context to understand undergraduates’ reasons for or benefits from college education, and to examine how the value relates to additional motivational goals, academic performance, and expected terminal degree.

Data analyses involved sophomores (n=729) who completed a learning-experience survey that included CAVS of the personal value and collective value subscales, expected terminal degree, Achievement Goal Questionnaire, and cumulative grade point average (CGPA). Construct validity evidence was substantiated by the results of exploratory factor analysis (n=364) for two-factor identification, and by the results of confirmatory factor analysis (n=365) for a good model-fit.

The interrelations between variables in regression analysis supported the predictive validity; achievement goals were predictors of CGPA, while personal value was a sole predictor of expected terminal degree. Findings suggest that CAVS is a predictive measure for Taiwanese undergraduates’ academic performance and choices.

In terms of policy implications, college students’ values of college attendance should not only be regularly investigated by institutional research, but should be widely applied by university students, educators and administrators to facilitate the optimal learning development for each undergraduate.

The study develops a short but effective scale of college-attendance value for the Taiwanese students who usually attend college after graduating from high school. The CAVS is useful in manifesting the students’ major reasons for pursuing college education.

This study empirically investigates the difference in employment status between marriage immigrants and native women in Taiwan based on a combined dataset from the 2003 Survey of Foreign and Mainland Spouses’ Life Status and 2003 Women’s Marriage, Fertility and Employment Survey. The conceptual framework is based on the family labor supply model, the human and social capital theories, and the immigrant assimilation theory. From the Probit model of the employment probability, our findings indicate that family background variables, including the presence of small children and husbands’ characteristics, play fairly significant roles in determining the employment probability of marriage immigrants. As for native women, human capital variables such as schooling and age are the most significant factors affecting their employment probability, while husbands’ characteristics play a less important role in this respect. The finding that the employment probability of foreign spouses rises rapidly with the number of years that have elapsed since migration may confirm the employment assimilation for marriage immigrants. This study further applies the nonlinear decomposition analysis developed in the work of Yun (2004) to examine the gap in employment probability between native women and foreign spouses in Taiwan. Our findings show that the employment probability differentials are mostly due to the difference in coefficients and that the effects of the two age variables play dominant roles. The difference in coefficients, in sum, contributes to increasing the gap of employment probability, while the difference in characteristics, in sum, tends to reduce the employment probability differentials.

This study takes advantage of abundant data from the Economics Department at National Tsing Hua University to empirically evaluate whether there exist academic performance differentials between undergraduate students from two entrance channels (exam-based and application-based methods) across courses and grades. We first evaluate the academic performance between the students based on two entrance channels, and then incorporate the General Scholastic Ability Test (GSAT) score (including five subjects of Chinese Literature, Mathematics, English, Science, and Society) into the independent variables to control for the students' ability. Our empirical results exhibit the students recruited through the application-based method outperform those admitted from the exam-based method in required courses after controlling for the students' individual characteristics. Nevertheless, we found that the advantage disappears for the elective courses. Furthermore, the academic gaps between the two groups of students tend to decline or disappear when students are seniors. The findings indicate that entrance exam scores (e.g., the Scholastic Assessment Test (SAT) scores in the United States) are good indicators for predict college academic performance, making the potential function of entrance exam in Taiwan relatively comparable to that in the United States. The findings also detail that individual GSAT scores on English, Math, and Society are positively and significantly associated with his/her performance on the core courses in Economics, supporting a significant learning progression from the curricula of senior high school to the undergraduate college education.

Using data from a top-five global executive placement firm, the authors explore how an organization's financial misconduct may affect pay for former employees not implicated in wrongdoing. Drawing on stigma theory, they hypothesize that although such alumni did not participate in the financial misconduct and they had left the organization years before the misconduct, these alumni experience a compensation penalty. The stigma effect increases in relation to the job function proximity to the misconduct, recency of the misconduct, and an employee's seniority. Collectively, results suggest that the stigma of financial misconduct could reach alumni employees and need not be confined to executives and directors that oversaw the organization during the misconduct.

Previous studies show that crude oil is negatively correlated with stocks but has almost the same rate of return as stocks, and so adding crude oil into a portfolio with equities can provide significant diversification benefits for the portfolio. Given the diversification benefit of crude oil mixed with equities, we examine the value effect of crude oil derivatives transactions by oil and gas producers. Differing from traditional corporate risk management literature, this study examines corporate derivatives transactions from the shareholders' diversification perspective. The results show that crude oil derivatives transactions by oil and gas producers do impact value. If oil and gas producing companies stop shorting crude oil derivatives contracts, company stock prices increase significantly. In contrast, if oil and gas producing companies initiate short positions in crude oil derivatives contracts, stock prices tend to drop (still significant, but less so). Thus, hedging by producers is not necessarily good. Transaction limitation is shown to be one of the possible sources of the value effect of corporate derivatives transactions.

When a stock is added into the S&P 500 Index, it in effect becomes cross-listed in the Index derivative markets. When index-based trading strategies such as index arbitrage are executed, the component stocks are directly affected by such trading. We find increased volatility of daily returns, plus increased trading volume for the underlying stocks. Utilizing a list of S&P 500 Index composition changes over the period September 1976 to December 2005, we study the market-adjusted volume turnover and return variance of the stocks added to and deleted from the Index. The results indicate that after the introduction of the S&P 500 Index futures and options contracts, stocks added to the S&P 500 experience statistically significant increase in both trading volume and return volatility. Both daily and monthly return variances increase following index inclusion. When stocks are removed from the index, though, neither volatility of returns nor trading volume experiences any significant change. So, we have new evidence showing that Index inclusion changes a firm's return volatility, and supporting the destabilization hypothesis.

We examine market response to changes in the annual “Dogs of the Dow” (DOD) portfolio. Specifically, we explore stock prices and trading volumes of the Dow stocks that are newly included into or excluded from the DOD portfolio. Although the historical performance of this popular dividend-driven investment strategy is subject to debate, our study focuses on investigating Harris and Gurel’s (1986) “noninformation-motivated demand shifts” in the sample of DOD additions and deletions. Utilizing standard event study methodology over the period 1996–2016, we find evidence that a Dow stock experiences a significant but temporary increase (decrease) in price when it is newly included into (excluded from) the DOD portfolio. Price reversals occur within one week of the reconstitutions. We also find that trading volumes temporarily increase following both index additions and deletions. The results support the price-pressure hypothesis as the DOD reconstitutions do not generally convey new information.

The issue of risk premium in commodity futures market has long been examined since Keynes’ (1930) normal backwardation hypothesis. We further examine the normal backwardation hypothesis in the gold futures market, using a Goldman Sachs Commodity Index (GSCI) approach. We find no evidence that risk premium exists in the gold futures market over the period 1980–2005. Finally, we provide further explanations as to why there is no risk premium in the gold futures market by investigating the actual gold futures positions taken by gold mining firms. We contend that lack of hedging activity by gold miners may explain the lack of risk premium in gold market.
