Regional and National Perspectives of China's Integration into the WTO: A CGE Inquiry with Emphasis on the Agricultural Sector

China's integration in the World Trade Organization (WTO) is already on its fast track. Understanding the complexity of China's dynamic adjustment resulting from its membership in the WTO and the differential regional impacts within China is very important and poses crucial challenge in evaluating its impacts. In this study, we make an attempt to incorporate seven regional commodity-detailed models into a dis-aggregated multi-sector and multi-region China Computable General Equilibrium (CGE) framework. This framework has allowed us to evaluate the impacts of China's integration into the WTO at both national and regional levels and analyze the inter-linkages between China's provincial agricultural markets. Using the framework and assumptions about factor mobility, we assess the impacts on China's agricultural and non-agricultural sectors (regionally and nationally) by reduction of its trade policy distortions, such as tariffs rate changes and quantitative restrictions. We also evaluate the structural changes on China's national and regional production and trade as China implements its commitments and moves into the WTO.     

THE EFFECTS OF COMPANY TRAINING,FURTHER EDUCATION AND THE YOUTH TRAINING SCHEME ON THE EARNINGS OF YOUNG EMPLOYEES*

Abstract This paper provides evidence on the impact of company training, of post-compulsory education and of the UK Youth Training Scheme in the late 1980's on the earnings of 21-year-old employees in England and Wales. Earnings equations are estimated for each of seven groups of employees who have followed alternative routes from compulsory education into employment, allowing for selectivity into these routes. There are several findings, including: both high parental social class and better school qualifications help to channel people into higher status routes, while high local unemployment has the opposite effect; participation in company training in long spells substantially raises wages but short spells do not; YTS participation fails to raise, and possibly substantially lowers, wages even three years after graduation compared to those who left school at 16 and went to work and received no training; there is weak evidence that, even for those that do not enter higher education, it is better to stay on at school after 16 than go into YTS.     

Range-Based Estimation of Stochastic Volatility Models

We propose using the price range in the estimation of stochastic volatility models. We show theoretically, numerically, and empirically that range-based volatility proxies are not only highly efficient, but also approximately Gaussian and robust to microstructure noise. Hence range-based Gaussian quasi-maximum likelihood estimation produces highly efficient estimates of stochastic volatility models and extractions of latent volatility. We use our method to examine the dynamics of daily exchange rate volatility and find the evidence points strongly toward two-factor models with one highly persistent factor and one quickly mean-reverting factor.     

Operations analysis—the promise and the pitfalls

Operations Analysis comes to education too highly recommended to be ignored, after having grown into wide usefulness in industry and government. Reservations about its use stem from the differences between industry and education. As the practitioners of Operations Analysis grew in numbers and experience, they became recognized agents in the constantly necessary changes in industry. Education, now lacking well-defined roles for Operations Analysis, might well seek the help of the private sector in using its tools. The pitfalls to be avoided, however, are: decision-making when only information is called for; problem definitions which yield triviality or over-generality; and failure to communicate convincingly to decision-makers. Operations Analysis can fail seriously when it starts from bad data or dubious premises, as well as when it uses ready-made methods without adaptation, or-worst of all-performs in a vacuum.     

Audit Committee Effectiveness in Victorian Local Government

This research addressed the questions: do audit committees (AC) in Victorian local government function effectively? Qualitative and quantitative data were collected to measure the perceptions, attitudes and perspectives of mayors, chief executives and chairs of the AC. The results were compared with perceptions of committee members of the Local Government and Shires Association of New South Wales and board members of the Municipal Association of Victoria as the representative bodies of local government in New South Wales and Victoria. There was a similarity of views in relation to: (1) inputs of an AC; (2) the behavioural nuances of the rigour of debate, trust and effective communications; and (3) the relationships with councillors and management. Limitations to effectiveness included: (1) attraction and retention of members; (2) the variability of expertise and the skills of the members; (3) continuing professional development for members; (4) ‘gaming’ behaviours; (5) power games associated with the appointment process; and (6) domination of the AC by members or management. The suggested way forward is the reinforcement of a strong governance culture in local government and an effective AC providing oversight of compliance, governance, internal control and risk processes.     

Analysing the performance of managed funds using the wavelet multiscaling method

We propose a new approach for investigating the performance of managed funds using wavelet analysis and apply it to an Australian dataset. This method, applied to a multihorizon Sharpe ratio, shows that the wavelet variance at the short scale is higher than that of the longer scale, implying that an investor with a short investment horizon has to respond to every fluctuation in the realized returns, while for an investor with a much longer horizon, the long-run risk associated with unknown expected returns is not as important as the short-run risk. Using multihorizon Sharpe ratios of six groups of managed funds, we find that none of the fund groups are dominant over all time scales.

The effect of audit firm size on audit prices: A study of the Australian Market

The effect of audit firm size on prizes is a complex function of competition in the market for audit services, product differentiation, and scale economics to large firms. In this study, a competitive market is supported in Australia with product differentiation to Bif Eight accounting firms. Specially, Big Eight accounting firms have significantly higher audit prices than non-Big Eight firms. This results holds for ‘large’ and ‘small’ auditees. A test is also made of price cutting in the Australian market. Price cutting is defined as lower initial audit fees than continuing engagement fees for a comparable audit. Test results do not evidence price-cutting behavior by accounting firms. There is in fact weak evidence that initial audit fees are higher than continuing engagement fee levels. Higher initial fees suggest that accounting firms may recover at least some of the audit start-up costs immediately.
