Income inequality and economic growth

Despite the extensive existing literature on income inequality and economic growth, there remains considerable disagreement on the effect of inequality on economic growth. Existing literatures find either a positive or a negative relationship. In this paper, we attempt to theoretically examine that relationship with a stochastic optimal growth model. We make the disagreement clear within a single model. We conclude (i) that both are possible – that is, higher inequality can retard growth in the early stage of economic development, and can encourage growth in a near steady state, (ii) that income redistribution by high income tax does not always reduce income inequality. Income inequality can be reduced by higher income tax in a near steady state, but it cannot be reduced in the early stage of economic development, and (iii) that two government polices – rapid economic growth and low income inequality – can be achieved by low income tax in the early stage of economic development, but both cannot be achieved simultaneously in a near steady state.     

Full versus quasi MLE for ARMA-GARCH models with infinitely divisible innovations

We compare the backtesting performance of ARMA-GARCH models with the most common types of infinitely divisible innovations, fit with both full maximum likelihood estimation (MLE) and quasi maximum likelihood estimation (QMLE). The innovation types considered are the Gaussian, Student’s t, α-stable, classical tempered stable (CTS), normal tempered stable (NTS) and generalized hyperbolic (GH) distributions. In calm periods of decreasing volatility, MLE and QMLE produce near identical performance in forecasting value-at-risk (VaR) and conditional value-at-risk (CVaR). In more volatile periods, QMLE can actually produce superior performance for CTS, NTS and α-stable innovations. While the t-ARMA-GARCH model has the fewest number of VaR violations, rejections by the Kupeic and Berkowitz tests suggest excessively large forecasted losses. The α-stable, CTS and NTS innovations compare favourably, with the latter two also allowing for option pricing under a single market model.     

Taiwan HRD practitioner competencies: an application of the ASTD WLP competency model

This paper aims to identify Taiwan HRD practitioners’ perceived competency levels, and to evaluate the importance of 52 workplace learning and performance (WLP) competencies. The conceptual framework is adapted from the American Society of Training and Development (ASTD) models for WLP conducted by Rothwell, Sanders and Soper (1999). The survey data were obtained from 254 practitioners, results are analysed and findings reported. Conclusions and recommendations are provided.     

A multivariate analysis of DISC election decision

Conclusion This study found that the decision by management to establish a DISC unit may not be satisfactorily identified by the examination of the financial data on either anex ante orex post basis. However, examination of the responses to the questionnaires indicate differences in the perceptions of the management of the two groups are significantly different on a multivariate basis.A possible implication of this research effort is that the use of published financial data alone cannot adequately explain decisions made by management. Indeed, unless management's expectations are realized, use of published data alone may result in unwarranted conclusions.     

Applying an extended theory of planned behavior to examine state-branded food product purchase behavior: The moderating effect of gender

ABSTRACT

The purpose of this study was to use an extended model of the theory of planned behavior to investigate the antecedents which lead to consumers’ purchase of state-branded food products. Relationships among attitude, subjective norm, perceived behavioral control, health-consciousness, intention to purchase, and actual purchase were examined. In addition, the moderating role of gender on consumer purchasing was assessed. The hypothetical model was empirically tested using data collected via Amazon Mechanical Turk (Mturk). Results implicated that consumers’ attitude, subjective norm, and perceived behavioral control of purchasing state-branded products significantly predicted their intention to purchase, and consumers’ intention to purchase significantly predicted their actual purchase of state-branded products. The relationship between health-consciousness and intention to purchase, however, was not found. Gender differences were found only between consumers’ perceived behavioral control of state-branded purchasing and their intention to purchase. Implications for marketers, farmers, and restaurant owners are provided.     

Electronic word-of-mouth (eWOM) generation in new media platforms: The role of regulatory focus and collective dissonance

In this research, we examine the role of two motivational forces associated with creation of electronic word-of-mouth (eWOM): regulatory focus and collective dissonance. Our studies show that generation of eWOM is enhanced by regulatory fit, while traditional WOM is dominated by the negativity effect. In study 1A, we show that prevention-focused consumers produce stronger intentions to post eWOM when they undergo a negative compared to a positive service experience. In study 1B, we find that promotion-focused consumers are more likely to post eWOM in reaction to a positive service experience when one's self-construal is independent. The final study shows that due to collective dissonance, consumers have greater intentions to create eWOM when their experiences are inconsistent with others' postings. We discuss the implications of these results for the development and management of eWOM communication in virtual communities.     

Delegation and dynamic incentives

Using an agency model, we show how delegation, by generating additional private information, improves dynamic incentives under limited commitment. It circumvents ratchet effects and facilitates the revelation of persistent private information through two effects: a play‐hardball effect, which mitigates an efficient agent's ratchet incentive, and a carrot effect which reduces an inefficient agent's take‐the‐money‐and‐run incentive. Although delegation entails a loss of control, it is optimal when uncertainty about operational efficiency is large. Moreover, delegation is more effective with production complementarity. We also consider different modes of commitment to yield insights into optimal organizational boundaries.
