An Examination of Organizational Commitment and Intention to Stay in the Timeshare Industry: Variations Across Generations in the Workplace

This study examines differences among individual generations’ organizational commitment and intention to stay in the timeshare industry. The timeshare segment is worthy of study due to expected growth and increase in worldwide lodging brands’ presence. Responses from more than 1,000 survey respondents reveal generational differences that highlight the variations in employee commitment and intention to stay. In addition to the contributions to literature for contemporary study among generational attitudes and behaviors, the implications may provide Human Resources practitioners insight into employee retention drivers relating to organizational commitment. Finally, this study adds to literature and practice by further clarifying generational differences.     

Determinants of Labor Market Participation and Wages of North Korean Female Refugees in South Korea

This paper uses data from a survey on 289 North Korean female refugees who arrived in South Korea in 2007 to understand the determinants of their economic adaption in the South Korean labor market. More specifically, we look at the effects of job finding channels and government policies on the labor market participation and wages of these women. We find that job finding through both personal contacts and public employment networks increases the probability of finding employment, but the former, especially job finding through contacts with South Koreans, is the most effective route to finding employment. In addition, jobs with higher wages are acquired in employment attained from South Korean referrals, followed by South Korean government agencies and those from North Korean refugee contacts. We further find that labor market participation is negatively affected by both public benefits and private transfers possibly because of increases in the reservation wages of job seekers.     

The Provision of Tax Services by Incumbent Auditors and Earnings Management: Evidence from Korea

This study examines the associations between the provision of tax services by incumbent auditors and earnings management. We investigate whether three different effects of tax service provision play different roles in accounting practices. The three effects include the audit independence effect, the knowledge spillover effect, and the tax avoidance effect. If the provision of tax services by incumbent auditors harms auditor independence, firms may exercise greater earnings management (audit independence effect). However, if incumbent auditors gain incremental knowledge by offering tax services, the quality of their audit services could be enhanced, and therefore, reported earnings could be more conservative (knowledge spillover effect). If tax service fee leads to low taxable income, it could depress book income when book-tax conformity is high (tax avoidance effect). We find that the provision of tax services generally improves earnings quality by curtailing opportunistic accounting practices. The results also suggest that the negative association between the provision of tax services and discretionary accruals seems to be primarily driven by the knowledge spillover effect as opposed to the tax avoidance effect. Additional analysis is conducted in examining whether the tax avoidance effect exists in a sub-sample.     

Consistency in meeting or beating earnings expectations and management earnings forecasts

This paper provides evidence that firms that have consistently met or beaten analysts’ earnings expectations (MBE) provide more frequent “bad news” management forecasts than firms with no established string of MBE, particularly when existing analyst forecasts are optimistic. This suggests that firms with a consistent MBE record are more likely to guide analysts’ expectations downward to avoid breaking the consistency. Subsequent analyst forecast revisions following bad news management forecasts issued by these firms are dampened, implying that analysts suspect that these forecasts may be opportunistic. The relation between management forecasts and MBE consistency is stronger after Regulation FD.     

Does Focus Really Matter? Specialized vs. Diversified REITs

REITs that limit their holdings to a single property type typically defend their lack of diversification by claiming the management possesses special investment expertise in that particular property type. This paper investigates whether property type specialized REITs outperform diversified REITs thus providing evidence of superior management expertise associated with specialized REITs. We compare the performance of specialized versus diversified REIT portfolios during 1997–2006 by examining abnormal returns using CAPM and the Fama-French three factor model with momentum. We find no evidence of superior performance associated with REITs specializing in a single property type. On the contrary, diversified REITs somewhat outperform specialized REITs, but not by a statistically significant margin. Also, consistent with theory, we find that specialized REITs have higher market risk than diversified REITs.     

Net neutrality and investment incentives

This article analyzes the effects of net neutrality regulation on investment incentives for Internet service providers (ISPs) and content providers (CPs), and their implications for social welfare. Concerning the ISPs' investment incentives, we find that capacity expansion decreases the sale price of the priority right under the discriminatory regime. Thus, contrary to ISPs' claims that net neutrality regulations would have a chilling effect on their incentive to invest, we cannot dismiss the possibility of the opposite. A discriminatory regime can also weaken CPs' investment incentives because of CPs' concern that the ISP would expropriate some of the investment benefits.     

Radiological findings of human fascioliasis

Fasciola hepatica is a trematode of herbivorous mammals. Humans are accidentally infected by the ingestion of water or raw aquatic vegetables contaminated with the metacercaria. Radiological findings of six patients with fascioliasis (five hepatic fascioliasis, one biliary fascioliasis) were analyzed. The diagnosis was based on serologic testing and/or histopathologic findings of eosinophilic abscess in five patients and identification of the adult worm in one patient. The characteristic radiological features of hepatic fascioliasis were (1) cluster of microabscesses arranged in tract-like fashion (burrow tract), (2) subcapsular location of the hepatic lesions, and (3) very slow evolution of the lesion on follow-up examinations. In biliary fascioliasis, there were multiple conglomerated filling defects in the common bile duct. The authors believe that the demonstration of these features, together with peripheral eosinophilia or eosinophilic aspirate from the hepatic lesion, is very helpful in making the correct diagnosis.     

Cost allocation of WCDMA and wholesale pricing for mVoIP and data services

This study estimates cost-based prices for wholesale voice and data services provided to 3G (WCDMA) MVNOs according to their distinct types. For estimation, 3G MVNOs are classified into different types, and the overall cost of WCDMA facilities are separated into voice and data components based on their subscriber rates, actual traffic rates, as well as efficiency consideration of traffic rates. The study then calculates cost-based wholesale prices of voice and data services for each of the 3G MVNO types. The result of this study shows that a cost-plus pricing scheme can help achieve the policy goals of the regulator, namely, lowering telecommunications tariffs and facilitating the introduction of new convergent-type services, far more effectively than the current retail-minus pricing scheme. The findings of this study may assist firms in developing business models based on 3G networks and telecom regulators in designing policies related to interconnection, mVoIP, prepaid calls, wholesale services, and network neutrality.     

Market implied future earnings and analysts’ forecasts

This study provides evidence on market implied future earnings based on the residual income valuation (RIV) framework and compares these earnings with analyst earnings forecasts for accuracy (absolute forecast error) and bias (signed forecast error). Prior research shows that current stock price reflects future earnings and that analyst forecasts are biased. Thus, how price-based imputed forecasts compare with analyst forecasts is interesting. Using different cost of capital estimates, we use the price-earnings relation and impute firms’ future annual earnings from three residual income (RI) models for up to 5 years. Relative to I/B/E/S analyst forecasts, imputed forecasts from the RI models are less or no more biased when cost of capital is low (equal to a risk-free rate or slightly higher). Analysts slightly outperform these RI models in terms of accuracy for immediate future (1 or 2) years in the forecast horizon but the opposite is true for more distant future years when cost of capital is low. A regression analysis shows that, in explaining future earnings changes, analyst forecasts relative to imputed forecasts do not impound a significant amount of earnings information embedded in current price. In additional tests, we impute future long-term earnings growth rates and find that they are more accurate and less biased than I/B/E/S analyst long-term earnings growth forecasts. Together, the results suggest that the RIV framework can be used to impute a firm’s future earnings that are high in accuracy and low in bias, especially for distant future years.
