Applying structural equation modeling to report psychometric properties of Chinese version 10-item CES-D depression scale

This study investigates the psychometric properties of Chinese-version short-form 10-item CES-D (i.e., CESD-10) in clinical depression patients and non-clinical college students by structural equation modeling approach. Several statistical procedures are applied to investigate the psychometric properties of CESD-10. First, the single factor model of CESD-10 shows merely mediocre fit due to “error term correlations”. The two pairs of error term correlations indicate that CESD-10 has redundant items and negative-worded effect. The revised model, based on the modification index, demonstrates good fit, and is adopted for subsequent analysis. Results of the SEM-based method show that configure invariance holds, while weak factorial invariance is not supported. A comparison the psychometric properties of the two groups shows that the clinical sample has better reliability, while the non-clinical sample has superior factorial validity. This finding confirms that the Chinese-version CESD-10 is most appropriate for the nonclinical, general population, although it is also valid for the clinically depressed.     

The valuation effects of bank loan ratings in the presence of multiple monitors

Studies have shown that when two information providers or outside auditors exist, the value provided by the second one will be decreased by the actions of the first. Credit rating agencies have been rating bank loans since 1996. Capitalizing on the highly similar functions performed by banks and these agencies, the informational value of bank loan ratings is examined. Further, evidence is provided on whether rating agencies duplicate the certifying and monitoring roles played by banks. The significant market reaction to negative bank loan rating announcements suggests these rating actions convey information beyond that provided via bank loan approvals and renewals.

The choice between civil service and entrepreneurship in the presence of credit rationing

This article examines the role of opportunities to be civil servants in determining both an individual’s ability to borrow to be an entrepreneur and his career choices that are related to the endowment of wealth. It is assumed that the civil servants are hired to produce the public goods or services that benefit all the entrepreneurs hiring workers to produce private goods. In considering the case where the position of a civil servant is randomly up for grabs without rent-seeking, it is known that the effect of a rise in the number of civil servants to be hired on an individual’s ability to borrow is mainly based on the improved efficiency and a rise in the wage due to an increase in the demand for workers. When the position of a civil servant is secured through rent-seeking, it is found that an improvement in the financial environment will lower the cost of rent-seeking if the welfare of the civil servant is not too high.     

Intellectual capital and new product development performance: The mediating role of organizational learning capability

Previous studies rarely examined the relationship between intellectual capital and organizational learning capability. Moreover, most studies neglect the mediating effect of organizational learning capability in the relationship between intellectual capital and new product development performance. This study uses interviews and the survey method to discuss the relationships governing intellectual capital, organizational learning capability, and new product development performance. Results are based on empirical data from Taiwan's IC design industry, and are generated by the Partial Least Squares (PLS) method. Results show that human capital and relational capital actually improve new product development performance through organizational learning capability. Although structural capital positively affects organizational learning capability, managers should pay attention to possibly negative effects of structural capital on new product development performance. Relational capital is the greatest factor among these three types of intellectual capital in Taiwanese IC design companies, structural capital is second, and human capital is last. Comparing three types of intellectual capital of Taiwan's large enterprises with those of Taiwan's small and medium enterprises (SMEs) reveals that the relational capital of Taiwan's SMEs is marginally less than that of large enterprises.     

Are governmental expenditures also sticky? Evidence from the operating expenditures of public schools

ABSTRACT

Existing research on cost stickiness focuses primarily on for-profit companies. This study investigates cost behaviour in the public sector, a new setting that deserves more research attention. Using unique data from public schools in Taiwan, we find that operating expenditures of public schools are sticky. Moreover, the stickiness is more prominent for schools whose principals facing higher enrolment pressure. These results support the public choice theory, suggesting that bureaucratic power may serve as a key driver leading to a sticky cost behaviour for governmental organizations. The government auditors and congressional representatives monitoring governmental budgets should thus notice that bureaucrats might keep the level of expenditures just for their self-interests when demand declines, a manifestation of distortion in allocation of social resources.     

Strategic Cost Management and Institutional Changes in Hospitals

Accounting research raises the concern that firms in the health care and defence contracting industries, when facing a dual payment system with both cost-based and fixed-rate payments, have an incentive to reallocate overhead costs through increasing inputs used in cost-based operations. However, prior literature reports contradictory empirical evidence regarding such real activity manipulation. Drawing on the institutional perspective, we hypothesise that firms' market power and interorganisational dependence affect their cost-management strategies and choice of overhead allocation in response to dual payment systems. Analysing the data of California hospitals from 1980 to 1991, we find that when facing a dual payment system, dominant (strong market position) hospitals adopt a cost-revenue-enhancing strategy, increasing direct costs for cost-based services without containing costs in fixed-rate services. In contrast, nondominant hospitals choose a cost-reduction strategy and improve operation efficiency on fixed-rate services. We also find that nondominant hospitals shift more overhead costs away from fixed-rate services to cost-based services by reclassifying the allocation bases across services; combining this cost shifting with the cost-reduction strategy, nondominant hospitals demonstrate the compliance with the regulation expectation of cost containment.     

Reliability evaluation and adjustment of supply chain network design with demand fluctuations

This study focuses on supply chain network design problems by considering economies of scale and demand fluctuations. A reliability evaluation method is developed to evaluate the performance of plants under demand fluctuations. In addition, two mathematical programming models are developed to determine the optimal adjustment decisions regarding production reallocation among plants under different fluctuating demands. The judgments to adjust or to do-nothing are investigated by comparing the results if the adjustment is made or not made. Results show that making adjustments benefits the manufacturers by reducing total production cost and avoiding revenue loss, which outweighs the extra costs, especially for high value-added products. Results also suggest that the manufacturer should ignore a short period abnormal state, since the benefits to respond to it might not compensate the high allocation costs. The results of this study provide a reference for the manufacturer in their decision making process of network planning with demand fluctuations, when they have to cope with benefits and costs during abnormal states.     

Inter-industry wage premiums and industry-specific productivity in Taiwan

By using Taiwan's Manpower Utilization Survey data for the 1978–2000 period, different inter-industry wage premiums in Taiwan are observed and the impact of workers’ industry-specific productivity on the wage explored. The empirical results show that industry-specific skills result in industry stayers having higher wages than industry switchers through their reservation wages. It is also found that the pre-displacement industry affiliations that are associated with the post-displacement wages are explained by the workers’ unobserved abilities. Furthermore, by comparing the different residual means between industry switchers and stayers based on each industry's wage equation, it is found that the switchers are low-wage workers who tend to be located in the high-wage industries. The high-wage industry leavers are also found to have higher post-displacement wage residuals than the low-wage industry leavers. These results suggest that the differences in industry wage premiums may be explained by the industry-specific productivity.     

A new choice of dynamic asset management: the variable proportion portfolio insurance

The constant proportion portfolio insurance (CPPI) achieves the advantage of simplicity due to its constant multiple. However, a dynamic multiple could improve the effectiveness of portfolio management. In this article, we provide a complete and detailed examination of the mechanism of variable proportion portfolio insurance (VPPI) strategy. The multiple of the VPPI states that when the stock price goes up, the multiple gets larger accordingly and when the stock price goes down, the multiple gets smaller. A portfolio insurance strategy with this discipline could yield better performance. Based on this principle, we recommend an exponential proportion portfolio insurance (EPPI). In addition, we also propose a new performance measure for portfolio insurance. Compared with the CPPI, simulation and empirical evidence support that the EPPI works better in both upside capture and downside protection, implying that the EPPI could be an effective tool for asset management.     

Does Outsourcing Always Benefit Skilled Labor?

This paper builds a dynamic product cycle model with three kinds of labor inputs—scientists, white‐collar workers, and blue‐collar workers—and producer heterogeneity to find an explanation for why outsourcing did not cause wage inequality in the 1970s. According to the theoretical model, outsourcing decreases the wages of white‐collar workers and the relative wages of white‐collar workers to blue‐collar workers in the outsourcing home country if outsourcing industries are blue‐collar worker intensive compared with non‐outsourcing industries. Scientists who conduct research and development always benefit from outsourcing.
