On the extent of speculative activity in the Indian stock market during badla and post-badla period

The authors test the existence of speculative activity in the Indian stock market during badla and post-badla period. They further investigate whether speculative activity migrated to single stocks futures market after banning of badla system. In both the tests it is found that there is no evidence of strong speculative activity in the Indian market. The research raises some questions on the regulators decision of banning badla system and sheds some light on the future decisions with respect to single stock futures market.

Simultaneous volatility transmissions and spillover effects: U.S. and Hong Kong stock and futures markets

Contemporaneous transmission effects across volatilities of the Hong Kong Stock and Index futures markets and futures volume of trade are tested by employing a structural systems approach. Competing measures of volatility spillover, constructed from the overnight U.S. S&P500 index futures, are tested and found to impact on the Hong Kong asset return volatility and volume of trade patterns. The examples utilize intra-day 15-min sampled data from this medium-sized Asia Pacific equity and derivative exchange. Both the intra- and inter-day patterns in the Hong Kong market are allowed for in the estimation process.

A review of the guidelines for ABC stock control

The paper summarises the methods promulgated in the literature for the design and maintenance of an effective inventory control system. Surprisingly, when it comes to putting theory into practice, the directives are often contradictory or opaque and their logic is inconsistent. Several published cases are dissected to try and rectify this parlous situation. In fact, the exercise soon reveals the heart of the problem. The classic EOQ model ignores the part played at the supplier’s end by efficient and responsive warehouse and transport operations. These activities depend greatly upon good advanced resource planning, which in turn is able to benefit from regular, cyclic, stock replenishment procedures.

Taking stock of school music education in Victoria: the lessons of history in the present context of the national review

The National Review of School Music Education represents a unique opportunity to identify and find solutions to some of the very long-standing problems in Australian school music education, particularly in the government school sector. This paper is based on the premise that there are lessons to be learned from the over 150 years of music education in Victorian government schools and that it is only by considering the current status, provision and quality of school music from an historical perspective and resolving emergent issues that effective and worthwhile music education can be provided for future generations of Australian students. Developments in school music education since the 1850s are discussed and analysed in terms of the present-day issues to be addressed by National Review and a number of mutually-dependent factors are identified as combining to produce almost cyclic patterns of ebb and flow in the status, provision and quality of music education in Victoria. The paper identifies several such factors requiring immediate attention including the inadequacy of generalist primary teacher education in music, what has effectively become the extra-curricular status of music in many government schools, and the more recent problems associated with 'the over-crowded curriculum' and the emergence of The Arts as the generic Key Learning Area in which Music now finds itself as just one of many arts disciplines. The paper concludes by making three key recommendations for consideration in the context of the current National Review of School Music Education.

Time-varying hedge ratios: an application to the Indian stock futures market

This paper investigates time-varying optimal hedge ratios in individual stock futures markets in India. The analysis employs data on individual stock futures from an unexplored but highly traded (both in terms of volume and quantity) emerging market. The hedge ratios derived in this study incorporate mean reversion in volatility, which is an important extension of the bivariate BEKK-GARCH model of Engle and Kroner. This extension generates improved optimal hedge ratios over the traditional BEKK-GARCH model and static error correction type alternatives.

Self-regulation: a risky option for developing countries? The case of Bangladesh

In recent years, the command and control type of government regulation is giving way to self- regulatory approaches in which industry sectors are responsible for controlling the conduct of their own members. Although self-regulatory approaches are increasingly being adopted with the objective of both improving the rate of compliance and reducing costs in developed countries, this paper argues that this might be a risky option. Developing countries often do not have adequate levels of standards of efficiency, effective legal regulatory frameworks, institutional safeguards and public awareness. Using the Bangladesh agriculture sector as an exemplar, this paper investigates the prospects of self-regulation of small businesses trading in agricultural inputs as a possible remedy for the recent problems associated with the sale of contaminated inputs to the farmers. The paper argues that self-regulation does not develop and is not sustained  independently of the context in which business operates. Importantly, the context includes the legal infrastructure created by the state and the enforcement effort imposed by the state. In the absence of effective state intervention in the public interest, institutional safeguards and public awareness, private entrepreneurs are less constrained to behave in the public interest and in conformity with the objectives of self-regulation. The findings of this paper provide significant implications for addressing the issue of effective regulation in developing countries.

Land retirement: a biodiversity policy for the rangelands of Western N.S.W.

In this article we examine land retirement as a biodiversity policy option for the rangelands of Western NSW, a region seriously under-represented in biodiversity provision. We argue that the use of policies that rely on moral suasion, education and minimal costsharing will not yield the level of on-farm biodiversity provision demanded by society. Instead, a much greater commitment to the use of monetary incentives to induce the voluntary cooperation and production of biodiversity is required. The analysis explains the importance in policy design of determining transparent, meaningful and achievable objectives in delivering cost-effective environmental outcomes. We propose a land retirement
policy that rakes account of environmental, economic and political criteria. Finally, our land retirement proposal is supported quantitatively by benefit-cost analysis.

Contemporaneous intra-day volume, option, and futures volatility transmissions across parallel markets

The primary objective of this article is to investigate volatility transmission across three parallel markets operating on the Sydney Futures Exchange (SFE), both within and out of sample. Half-hourly observations are sampled from transaction data for the share price index (SPI) futures, SPI futures options, and 90-day bank accepted bill (BAB) futures markets, and the analysis is carried out using the simultaneous volatility (SVL) system of equations as well as competing volatility models. The results confirm the poor ability of GARCH models to fit intraday data. This study also applies an artificial nesting procedure to evaluate the out-of-sample volatility forecasts. Implied volatility has very limited (if any) predictive power when evaluated in isolation, whereas the SVL model with implied volatility embedded provides incremental information relative to competing model forecasts.

Time varying hedge ratios : an application to the Indian stock futures market

The analysis employs data on individual stock futures from an unexplored but highly traded (both in terms of volume and quantity) emerging market. The hedge ratios derived in this study incorporate mean reversion in volatility, which is an important extension of the bivariate BEKK-GARCH model of Engle and Kroner. This extension generates improved optimal hedge ratios over the traditional BEKK-GARCH model and static error correction type alternatives.

Electrosorption: an alternative option for desalination

Electrosorption is generally defined as adsorption on the surfaces of charged electrodes by applying potential or current. Electrosorption deionization method is a low-pressure non-membrane deionization process, with the potential to be a low energy cost alternative for desalination in the future. In this paper, the principle and mechanism of the electrosorption deionization method are discussed, the materials and properties of the electrode used in electrosorption process are summarized and the application and prospect of this promising desalination method are reviewed.

Mean reversion in stock prices: new evidence from panel unit root tests

Purpose – There are several studies that investigate evidence for mean reversion in stock prices. However, there is no consensus as to whether stock prices are mean reverting or random walk (unit root) processes. The goal of this paper is to re-examine mean reversion in stock prices.
Design/methodology/approach – The authors use five different panel unit root tests, namely the Im, Pesaran and Shin t-bar test statistic, the Levin and Lin test, the Im, Lee, and Tieslau Lagrangian multiplier test statistic, the seemingly unrelated regression test, and the multivariate augmented Dickey Fuller test advocated by Taylor and Sarno.
Findings – The main finding is that there is no mean reversion of stock prices, consistent with the efficient market hypothesis.
Research limitations/implications – One issue not considered by this study is the role of structural breaks. It may be the case that the efficient market hypothesis is contingent on structural breaks in stock prices. Future studies should model structural breaks.
Practical implications – The findings have implications for econometric modelling, in particular forecasting.
Originality/value – This paper adds to the scarce literature on the mean reverting property of stock prices based on panel data; thus, it should be useful for researchers.

Is money targeting an option for Bank Indonesia?

In this paper, using the cash-in-advance model, we estimate Indonesia's money demand function for the period 1970–2005. We find the real M1 and real M2 are cointegrated with their determinants, namely real income, real exchange rate and short-term domestic and foreign interest rates. The long-run elasticities, except for the relationship between M2 and domestic interest rate, are plausible. Interestingly, we find a negative relationship between real exchange rate and real money demand, suggesting evidence of currency substitution. We test for causal relationships and find that in the short-run only the real exchange rate Granger causes real M1 and real M2. Finally, we find that Indonesia's money demand functions are unstable. We conclude that money targeting is not an option for Bank Indonesian and that currency substitution should be curbed in order to ensure macroeconomic sustainability.
