EUROPE – HOW CAN THINGS GET BETTER?

In the 2010 Wincott Lecture, the author – a former European Commissioner – explains how the process of policy‐making within the European Union can be improved. In order to gain the full benefits of an open and integrated single market, the EU must stop interfering in areas that should properly be the responsibility of member states. However, in the context of the current economic crisis, the EU should take a greater role in financial regulation and in ensuring fiscal responsibility among members of the eurozone.     

INPUT–OUTPUT ANALYSIS FOR BUSINESS PLANNING: A CASE STUDY OF THE UNIVERSITY OF SYDNEY

We present a multi-region input–output (MRIO) model of the University of Sydney embedded in the Australian economy, which forms the centrepiece of a new data-driven framework for strategic forecasting and planning of the University's financial operations. This framework incorporates both Leontief's well-known demand-pull, as well as Ghosh's supply-push exercise. It is therefore able to estimate the immediate financial implications for the University, and the economy-wide flow-on effects, for example as a result of changes in demand for courses by students, or as a result of supply-side changes such as wage increases. We report on recent scenario studies on the financial performance of the teaching and research functions of the University, and the lessons learned for management practice.     

Exit and Entry Over the Product Life Cycle: Evidence from the Swedish Manufacturing Industry

In this paper the process of exit and entry of firms in the Swedish manufacturing industry is investigated within the framework of the product life cycle. The product life cycle theory explains how the high degree of uncertainty, as regards product designs and production methods, which is connected to the early stages of the product life cycle requires a high level of knowledge-intensity. Since uncertainty decrease over the product life cycle, less knowledge is needed in production during later stages of the product life cycle. This implies that knowledge-intensity differs for firms that exit and enter in different stages of the product life cycle. Four hypotheses regarding these relationships are stated and empirically tested in this paper, using data at the 5-digit SIC-level for the Swedish manufacturing industry during 1990–1996. The empirical results show that entrants in the early stages of the product life cycle are more knowledge-intensive than incumbent firms. It is also found that firms exiting in early stages of the product life cycle are more knowledge-intensive than firms exiting in later stages.     

Do Company Directors Underestimate the Adoption of Corporate Governance Provisions？ A Survey Approach

This paper examines whether company directors underestimate the adoption of corporate governance provisions within Ghanaian listed firms. Using a survey approach, the respondents, who were company executives and non-executive directors with knowledge of the Ghanaian Code and its provisions, regard the code as a benchmark for good corporate governance practices within Ghanaian listed firms. They also report some improvement in the standard of corporate governance in their companies since the introduction of the Code. Many of the company directors indicated their preparedness to comply with further corporate governance requirements, such as the adoption of a formal nomination committee something not been currently included in the Ghanaian Code. However, the directors noted that they receive inadequate support from the regulatory and institutional bodies for the implementation of the Ghanaian Code provisions. Many of the directors also supported the review of the Ghanaian Code by an independent committee. With regard to the adoption of the Ghanaian Code and its influence on firm performance, the respondents indicated that the adoption of the specific governance provisions in the area of chief executive officer （CEO）/chairman roles separation, having a balance of executive and non-executive directors on the board, the establishment of audit and remuneration committees, and the full adoption of the Ghanaian Code provisions were all influential in determining firm performance. They, however, did not support the adoption of the board size provision as influential to firm performance. This raises questions about the usefulness of the range of board size as recommended by the Ghanaian Code.

Market Efficiency and Returns to Simple Technical Trading Rules: Further Evidence from U.S., U.K., Asian and Chinese Stock Markets

Tian, Wan and Guo (2002) explored the predictability and profitability of technical trading rules in markets with different efficiency levels; namely, the U.S. and China. In the case of the U.S. they found rules to have no predictability after 1975, whereas their results give support to technical trading rules having both predictability and profitability for the Chinese markets across the 1990's. The purpose of this paper is to extend the analysis of Tian et al. in two ways. First, to see if the conclusions extend to other markets – namely, the U.K., Hong Kong and Japan. Second, in the case of China, to examine whether the predictability and profitability of technical trading rules changed across the 1990's. On the basis of daily data Tian et al's results for the U.S. market are supported by the results for a number of the main developed markets where the technical trading rules had predictive ability during the 1970's that disappeared by the 1990's. Furthermore, the results suggest that while technical trading rules had short term predictive ability and profitability in the Chinese stock markets during the 1990's, this lessened as the decade progressed.

Information asymmetry in warrants and their underlying stocks on the stock exchange of Thailand

This paper examines the informational role of warrants based on the unique order data from the Stock Exchange of Thailand, where both warrants and stocks are traded under the same market structure and where warrants are as liquid as stocks. The estimated probability of informed trading (PIN) in warrants is found to be statistically higher than their underlying stocks regardless of order submission type and order size. The PIN explains a substantial portion of the cross-sectional variation in the opening spread beyond trading volume and minimum tick size. We find evidence that a signed warrant trade contains information about the future stock price and that warrants with a higher PIN have greater predictive powers.
