Measuring Employee's Creativity: A New Theoretical Model and Empirical Study for Tourism Industry

Based on the componential theory of creativity, this research built and tested a new theoretical model that links the 4P model (people, product, place, and process) with creativity via several intervening variables. Survey data and two-step structural equation modeling were used to evaluate a sample of 338 employees surveyed from 57 tourism and hospitality organizations in Taiwan. As anticipated, we found that people (e.g. personality) positively affected place (e.g. organizational environment and participation) and creative process (e.g. data collection, idea generation, and confirmation), which in turn influenced product outputs of creativity and satisfaction.     

Niche and performance: the moderating role of network embeddedness

What is the relationship between niche and performance? We identify two types of niche positions—product niche and process niche—defined by the extent to which a firm offers distinctive products and has distinctive operational processes, respectively. We argue that the effect of each niche on firm performance is contingent upon network embeddedness—the extent to which a firm is involved in a network of interconnected inter‐firm relationships. Using data covering the period 1995–98 pertaining to venture capital firms and their holdings in initial public offerings (IPOs), we show that both product niche and process niche interact with network embeddedness to determine firm performance. Our findings suggest that the extent to which a firm offers distinctive products or processes will be more positively associated with firm performance when network embeddedness is high.

The trading behavior of foreign,domestic institutional,and domestic individual investors: Evidence from the Taiwan stock market

In this paper, we apply the threshold cointegration model of Hansen and Seo (2002), incorporating differences in the nonlinear behavior of investors across regimes. An examination of the trading behavior of foreign, domestic institutional, and domestic individual investors in Taiwan revealed no predominance among the three types of investors. When the market was near equilibrium, the purchases of domestic individual investors positively impacted stock prices. This finding, which is consistent with Choe et al. (2005), suggests that domestic individual investors have an edge in investment performance over other types of investors. However, when the market departed substantially from equilibrium, the purchases of foreign and domestic institutional investors predicted a rise in stock prices. On the other hand, domestic individuals traded at worse stock prices; these prices tended to fall (rise) after the purchase (sale).     

Underwriter reputation,earnings management and the long‐run performance of initial public offerings

This study contributes to the extant literature on the nature of earnings management surrounding initial public offerings (IPOs) by investigating the role of underwriter reputation. We argue that prestigious underwriters will protect their reputation by carefully monitoring and certifying financial information on IPO firms, thereby limiting any potential earnings manipulation. As a result, those IPO firms that are associated with more prestigious underwriters are likely to exhibit substantially less‐aggressive earnings management. Conversely, we find the existence of a negative relationship between earnings management and the post‐offer performance of an IPO firm’s stocks only for those firms associated with less‐prestigious underwriters.     

An Optimal Product Mix for Hedging Longevity Risk in Life Insurance Companies: The Immunization Theory Approach

This article investigates the natural hedging strategy to deal with longevity risks for life insurance companies. We propose an immunization model that incorporates a stochastic mortality dynamic to calculate the optimal life insurance–annuity product mix ratio to hedge against longevity risks. We model the dynamic of the changes in future mortality using the well‐known Lee–Carter model and discuss the model risk issue by comparing the results between the Lee–Carter and Cairns–Blake–Dowd models. On the basis of the mortality experience and insurance products in the United States, we demonstrate that the proposed model can lead to an optimal product mix and effectively reduce longevity risks for life insurance companies.     

A multiple objective particle swarm optimization approach for inventory classification

This paper presents a particle swarm optimization approach for inventory classification problems where inventory items are classified based on a specific objective or multiple objectives, such as minimizing costs, maximizing inventory turnover ratios, and maximizing inventory correlation. In addition, this approach determines the best number of inventory classes and how items should be categorized for the desired objectives at the same time. Experiments are employed to determine the best combination of algorithm parameter values. Extensive numerical studies are conducted and results are compared to other known classification methods. The performance of the algorithm on a practical case is also presented.     

What drives foreign expansion of the top 100 multinational banks? The role of the credit reporting system

This study explores how information costs, proxied by characteristics of credit reporting systems, affect the foreign expansion of the top 100 multinational banks. We find that banks prefer to expand operations in countries where private credit bureaus exist or where the credit reporting system is of better quality. This preference is particularly strong for banks’ branch decisions. Furthermore, banks prefer subsidiary entry only in countries where private credit bureaus exist with better credit information quality. Overall, our results indicate that banks are attracted to countries where the credit reporting system helps reduce banks’ information costs.     

Entrepreneurial orientation and firm performance: The role of knowledge creation process

This study examines the relationships among entrepreneurial orientation, knowledge creation process, and firm performance using survey data from 165 entrepreneurs. We use LISREL analysis to test the direct and indirect effects of the entrepreneurial orientation on firm performance. Knowledge creation process - operationalized to reflect the dimensions of socialization, externalization, combination, and internalization - is used as the mediating variable for explaining the relationship between entrepreneurial orientation and firm performance. The results indicate that the significance of the direct effect of entrepreneurial orientation on firm performance is reduced when the indirect effect of entrepreneurial orientation through knowledge creation process is included in a total effect model. Consequently, entrepreneurial orientation is positively related to firm performance, and knowledge creation process plays a mediating role in this relationship.     

Closed-Form Mortgage Valuation Using Reduced-Form Model

Valuing mortgage-related securities is more complicated than valuing regular defaultable claims due to the borrower's prepayment behavior as well as the possibility of default. Some researchers use a structural-form model to obtain the closed-form formulas for the mortgage value. With this method, however, it is difficult to identify the critical region of early exercise. As an alternative, the reduced-form model developed in this article is able to value the mortgage without setting boundary conditions, and it can thereby accurately handle the multidimensional space of correlated state variables. The purpose of this article is to derive a closed-form solution of the mortgage valuation equation under a general reduced-form model that embeds relevant economic variables. This new approach enables portfolio managers to undertake sophisticated portfolio optimization and hedging analyses. An implementation procedure for the model is also provided to demonstrate how the valuation framework can be utilized in practical applications.     

Criterion-robust optimal product designs for discrimination between nested response surface models

Consider the problem of discriminating between two rival response surface models and estimating parameters in the identified model. To construct designs serving for both model discrimination and parameter estimation, the M _γ-optimality criterion, which puts weight γ (0≤γ≤1) for model discrimination and 1 − γ for parameter estimation, is adopted. The corresponding M _γ-optimal product design is explicitly derived in terms of canonical moments. With the application of the maximin principle on the M _γ-efficiency of any M _γ'-optimal product design, a criterion-robust optimal product design is proposed.
