Use of loan loss provisions for capital, earnings management and signalling by Australian banks

This study examines whether and to what extent Australian banks use loan loss provisions (LLPs) for capital, earnings management and signalling. We examine if there were changes in the use of LLPs as a result of the implementation of banking regulations consistent with the Basel Accord of 1988, which made loan loss reserves no longer part of Tier I capital in the numerator of the capital adequacy ratio. We find some evidence to indicate that Australian banks use LLPs for capital management, but we find no evidence of a change in this behaviour after the implementation of the Basel Accord. Our results indicate that banks in Australia use LLPs to manage earnings. Furthermore, listed commercial banks engage more aggressively in earnings management using LLPs than unlisted commercial banks. We also find that earnings management behaviour is more pronounced in the post‐Basel period. Overall, we find a significant understating of LLPs in the post‐Basel period relative to the pre‐Basel period. This indicates that reported earnings might not reflect the true economic reality underlying those numbers. Finally, Australian banks do not appear to use LLPs for signalling future intentions of higher earnings to investors.     

Hedging performance of multiscale hedge ratios

In this study, the wavelet multiscale model is applied to selected assets to hedge time-dependent exposure of an agent with a preference for a certain hedging horizon. Based on the in-sample and out-of-sample portfolio variances, the wavelet-based generalized autoregressive conditional heteroskedasticity (GARCH) model produces the lowest variances. From a utility standpoint, wavelet networks combined with GARCH have the highest utility. Finally, the wavelet-GARCH model has the lowest minimum capital risk requirements. Overall, the wavelet GARCH and wavelet networks offer improvements over traditional hedging models.     

Analysis of visual presentation of cultural dimensions: Culture demonstrated by pictures on homepages of universities in Pakistan

The recent prominence of culturally rich visuals for effective global communication and establishing brands of organizations cannot be denied. This inquest observed how Pakistan universities used their homepages to demonstrate culture through a content analysis of 1064 pictures from 100 top universities. The researcher tried to take a stance on visual presentation of cultural aspects by using Hofstede’s cultural dimension theory, and evaluated the impact of cultural elements in choosing pictures as part of web design and marketing strategy. Results indicated that faculty in groups doing academic and official activities were the predominant visual element, and websites mostly marketed faculty. Choice of pictures was positively correlated with Hofstede’s scores on power distance, individualism, uncertainty avoidance and indulgence, but a different trend was observed for masculinity and pragmatism. Findings suggest that institutions should ameliorate their web marketing according to cultural needs of local as well as international students, and further research is needed.     

Marginal risk aversion and preferences in a betting market

An individual's behavioural attitudes toward variance and non-symmetry in the payoff distributions of pari-mutuel gambles are empirically examined using the von Neumann - Morgenstern expected utility of wealth paradigm. Preferences over payoff distributions for a representative bettor are estimated from observed payoffs at a greyhound racetrack. The results indicate that the representative bettor exhibits increasing absolute risk aversion and, given that the representative bettor is locally non-satiated with regard to wealth, exhibits preference for variance and aversion to positive skewness in the payoff distributions of the gambles examined.     

Single‐loop project controls: Reigning paradigms or straitjackets?

This article reports on the results from an ongoing research program to study the role mental models play in project decision making. Project management belongs to the class of multiloop nonlinear feedback systems, but most managers do not see it that way. Our experimental results suggest that managers adopt simplistic single‐loop views of causality, ignore multiple feedback interactions, and are insensitive to nonlinearities. Specifically, the article examines single‐loop models of project planning and control, discusses their limitations, and proposes tools to address them.     

Imperfect Labor Mobility and Unemployment in LDCs: Reply

In a recent paper (Parai and Beladi 1997; PB hereafter), we have analyzed the implications of growth and trade policies for a small open economy facing imperfect labor mobility and unemployment of the Harris-Todaro variety. We have used the Casas (1984) specification of the labor immobility phenomenon for a Harris-Todaro type economy, and have shown that most of the results in Harris-Todaro framework remain unaltered even under imperfect labor mobility, provided that the elasticity of labor mobility parameter exceeds a critical minimum value. On the optimal tariff issue, Gilbert and Mikic (1997; GM hereafter) find our results counterconventional. In GM's view, the nonconventional result in PB is due to our simplification of the labor mobility specification given by Casas. In this note, we offer our response to GM's comments.     

Government intervention and institutional trading strategy: Evidence from a transition country

This study investigates the effectiveness of government intervention in rescuing bearish markets in a transition economy. Focusing on a pre- and a post-intervention period, the findings reveal that government intervention successfully rescued bearish markets in China and led to a fundamental change in institutional trading strategy after the intervention. We observe that following an intervention, institutions are more sensitive to long-term stock market regulations, whereas individual investors are more concerned about the rules related to their short-term interests. Evidence suggests that a credible signal from the government can be helpful in creating a positive outcome in the market (Bhanot & Kadapakkam, 2006). The findings are important to the current debate regarding the role of government intervention in markets in other transitional economies, as well as in developed countries.
