Government Size and Stochastic Growth

This paper analyses the effects of the size of government on economic growth in a stochastic endogenous growth model involving the supply‐side effect and demand‐side effect produced by government spending. We show that a rise in the government spending affects economic growth through three channels, including the crowding‐out effect, the spin‐off effect and the resource mobilisation effect. We demonstrate that there exists an optimal size of government that maximises the economic growth rate.     

Stock price responses to the eco-points programme for electrical household appliances: evidence from Japan

This article examines the Japanese government’s ‘Project for Green Consumer Electronics to Promote Business through the Use of Eco-points’ and its economic impact on consumer electronics firms’ stock prices. There has been little research on the economic effect of this project. In order to achieve our aim, we employ event study methodology. Our results show that stock prices responded positively to programme adoption, thereby indicating that the programme had positive effects on the related firms’ performance. The results also show that the programme’s economic effects gradually decreased over each subsequent programme extension. This probably occurred because the programme targeted durable goods, which consumers do not replace frequently.     

Effects of China's Structural Change on the Exports of East Asian Economies

The Chinese economy is slowing down and is in the midst of a structural transformation from export‐led and investment‐led growth to domestic demand‐led and consumption‐led growth. While there are widespread concerns among China's trading partners about the effect of the slowdown in China's growth on their exports, China's structural changes are also likely to have a significant impact: for example, China will import fewer machines and more cosmetics. The central objective of the present paper is to empirically examine the effect of China's structural transformation on the exports of East Asian economies, which have close trade linkages with China. We find that economies that have failed to increase the share of consumption goods in their exports to China have suffered larger declines in their quantities of exports to China. In addition, economies that have suffered losses in their shares of China's parts and components imports have faced reductions in their shares in China's total imports.     

The generality of spurious predictability

Previous empirical work has documented significant predictability (non-zero cross autocorrelations) in short-term security returns. Extant theoretical papers have shown that these cross autocorrelations can arise due to partial impounding of information in securities whose returns are driven by a common factor. In this paper, we show that non-zero cross autocorrelation in security returns can arise under weaker conditions than is generally known. We demonstrate that the existence of cross autocorrelations crucially depends on the information structure of informed traders. Thus, a common factor in security returns is neither sufficient nor necessary. Any one of the following conditions on the information structure can generate non-zero cross autocorrelations:

(1) existence of an informed trader with information relevant to two securities;

(2) correlation in the signal of informed traders with information relevant to different securities; or

(3) correlation in uninformed trading.

These cross autocorrelations are then shown to be spurious. That is, traders without any private information cannot make positive trading profit by exploiting cross autocorrelations.     

Hotel job burnout: The role of personality characteristics

In hospitality and tourism academia, most research focuses on the work domain as a major source of hospitality job stress, with little attention given to employee characteristics. This study examines the effect of the Big Five personality dimensions (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience) on hotel employees’ job burnout. After controlling for two commonly known job burnout antecedents (autonomy and quantitative workload), study results indicate that personality attributes explain significant proportions of three job burnout factors. The most noteworthy finding is the predictability of the agreeableness trait in hotel employees’ job burnout. Because of the mixed results reported on the relationship between this trait and job stress in other disciplines, more vigorous future research is recommended to validate the value of this personality to the hospitality industry.     

Tempered stable and tempered infinitely divisible GARCH models

In this paper, we introduce a new GARCH model with an infinitely divisible distributed innovation. This model, which we refer to as the rapidly decreasing tempered stable (RDTS) GARCH model, takes into account empirical facts that have been observed for stock and index returns, such as volatility clustering, non-zero skewness, and excess kurtosis for the residual distribution. We review the classical tempered stable (CTS) GARCH model, which has similar statistical properties. By considering a proper density transformation between infinitely divisible random variables, we can find the risk-neutral price process, thereby allowing application to option-pricing. We propose algorithms to generate scenarios based on GARCH models with CTS and RDTS innovations. To investigate the performance of these GARCH models, we report parameter estimates for the Dow Jones Industrial Average index and stocks included in this index. To demonstrate the advantages of the proposed model, we calculate option prices based on the index.
