Untangling the relationships between consumer characteristics,shopping values,and behavioral intention in online group buying

This study examines the link among consumer characteristics (price-sensitive behavior, variety-seeking behavior, and compulsive buying behavior), shopping values (utilitarian and hedonic shopping values), and behavioral intention in online group buying (OGB). This study tests usable responses collected by means of mall-intercept systematic sampling from consumers who previously participated in OGB. Structural equation modeling was used to analyze data and test the hypothesized relationships. Findings suggest that price-sensitive and variety-seeking behaviors are significantly related to utilitarian shopping value, whereas price-sensitive, variety-seeking, and compulsive buying behaviors are significantly related to hedonic shopping value. Both utilitarian and hedonic shopping values significantly influence consumers’ OGB intentions. For a successful OGB strategy, Internet marketers and site operators should emphasize the utilitarian shopping value of price saving and selection and introduce the hedonic shopping values of promotions and sensory experiences. This study provides a link between two streams of prior research – that is, consumer characteristics and shopping values. Furthermore, it validates an empirical model whose results can help business practitioners make better-informed marketing management decisions for OGB and help academics and consumers better understand OGB behavior.     

Time series test of nonlinear convergence and transitional dynamics

This paper revisits the income convergence hypothesis by using the nonlinear unit root test of Kapetanios et al. [Kapetanios, G., Shin, Y. and A. Snell, 2003. Testing for a unit root in the nonlinear STAR framework. Journal of Econometrics 112, 359–379.]. Out of the 12 OECD income gaps in which nonlinearity has been detected, two cases of long-run converging and four cases of catching up are found.     

Assessing the psychometric properties of the Dimensions of the Learning Organization Questionnaire in the Korean business context

The primary purpose of this research is to adapt the Dimensions of the Learning Organization Questionnaire developed by Watkins and Marsick, and examine its validity and reliability in a Korean context. Although the concept of the learning organization is well established, there has not been rigorous validation of the application of the questionnaire in the Korean context. The present research sheds light on the reliability and validity of applying the learning organization concept to the Korean workforce. The results of confirmatory factor analysis and internal consistency tests indicate that the Korean version of the questionnaire produces valid and reliable psychometric properties of learning organization characteristics in a Korean cultural context. Several demographic variables were used to identify the differences in learning organization cultural perspectives. Conclusions and implications are set out and the limitations of the research stated.     

An exploratory study of factors affecting the failure of local small and medium enterprises

There is increasing recognition of the potential contribution of local small and medium enterprises (SMEs) towards employment and economic growth in Singapore. Unfortunately, SMEs tend to have a high mortality rate. A survey was conducted among owners or managers of local SMEs to identify factors perceived as important in affecting business failures. The research results indicate that endogenous factors were viewed by respondents as more critical in causing SME failures than exogenous factors. Important exogenous and endogenous factors in specific areas were identified.Lau Geok Theng is Senior Lecturer, Department of Marketing, National University of Singapore, 10 Kent Ridge Crescent, Singapore 0511, tel: (65) 772-3179, fax: (65) 779-5941.

Time-based competition: Some empirical data from Singapore

The progressive edge of competition has moved from what was primarily a cost-based strategy through that which was quality-based, and then variety-based, and now, onto the time-based mode of competition. This paper presents a status report of the response of the Singapore manufacturing sector to such a progression in competitive paradigms. In particular, we will refer to empirical data from the latest Singapore Manufacturing Futures Survey to provide an update on the apparent status of the local manufacturing environment in terms of such current paradigms of competition. From these, we will draw some implications for operations management, that is, what should local producers and suppliers do in the light of such current modes of competition. Such implications may be of help to other manufacturing businesses operating in other countries.The author is with the Department of Decision Sciences, National University of Singapore, 10 Kent Ridge Crescent, Singapore 0511.     

Tests for zero inflation in a bivariate zero‐inflated Poisson model

The score test statistics for testing zero inflation and covariance parameter are proposed in the bivariate zero‐inflated Poisson (BZIP) regression model. The Monte Carlo studies show that the score test and likelihood ratio test for testing zero inflation underestimate the nominal significance level, while the score test for covariance parameter keeps the significance level close to the nominal one. To overcome this nominal level underestimation, we propose a bootstrap method of the score test for the testing problem of zero inflation. An empirical example with covariates is provided to illustrate the results. In addition, score test for zero inflation is also proposed in the BZIP model, which allows a flexible dependence structure using copula.     

合并纳税制度的国际比较及对中国的启示

发达国家为了提高本国企业的国际竞争力、吸引投资,普遍实施企业集团合并纳税制度。我国现行的合并纳税制度在保持税收公平和税收中性、控制国内税收流失和国有资产流失、国际税收协调等方面存在诸多不完善之处,不仅使中国企业集团在国际市场上处于不利位置,也制约了企业的稳定发展。因此,应通过比较和分析中国与其他国家的企业集团合并纳税制度,找出中国合并纳税制度的不足之处,并加以完善。     

Reduced-form Models with Regime Switching: An Empirical Analysis for Corporate Bonds

Empirical evidence shows that there is a close link between regime shifts and business cycle fluctuations. A standard term structure of interest rates, such as the Cox et al. (1985 Econometrica, 53, 385–407; CIR) model, is sharply rejected in the Treasury bond data. Only Markov regime-switching models on the entire yield curve of the Treasury bond data can account for the observed behavior of the yield curve. In this paper, we examine the impact of regime shifts on AAA-rated and BBB-rated corporate bonds through the use of a reduced-form model. The model is estimated by the Efficient Method of Moments (EMM). Our empirical results suggest that regime-switching risk has significant implications for corporate bond prices and hence has a material impact on the entire corporate bond yield curve, providing evidence for the approach of rating through the cycle employed by rating agencies.     

A non‐lattice pricing model of American options under stochastic volatility

In this article, an analytical approach to American option pricing under stochastic volatility is provided. Under stochastic volatility, the American option value can be computed as the sum of a corresponding European option price and an early exercise premium. By considering the analytical property of the optimal exercise boundary, the formula allows for recursive computation of the American option value. Simulation results show that a nonlattice method performs better than the lattice‐based interpolation methods. The stochastic volatility model is also empirically tested using S&P 500 futures options intraday transactions data. Incorporating stochastic volatility is shown to improve pricing, hedging, and profitability in actual trading. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:417–448, 2006
