Neoliberalising learning : generating alternate futures consciousness

Both educators and education policies have long claimed a role in preparing students for ‘the future’. This has been referred to as the rhetoric of futures in education, as the notion of a future is assumed, abstract and not articulated (Bateman 2010). Recent research indicates that teachers give little attention to futures thinking in interpreting and enacting curriculum documents. Only when their ‘futures consciousness’ was increased were they able to generate explicit alternate futures scenarios and make connections with learners (Bateman 2012). In light of international education policy agendas pressing countries to adopt economic competitiveness in national curriculum policies, the ‘future’ vision looks narrow and constrained. We argue that current educational reforms in Australia provide little scope to address the concept of multiple futures, which are significant in enabling citizens to shape and contribute in personal, local and global contexts.

Conceptualising challenges for teachers and learning futures

The assumption that all education prepares students for their futures is misguided. Rather, students are prepared, through curriculum and institutional practices for politically constructed notions of the future, which are often based on another assumption that what has worked in the past will continue to work in the future. This is evident in the absence of articulated futures within curriculum and other policy documents. This research showcases a critical ethnography which was undertaken in a Victorian primary school. The specific project focussed on the ways in which Year 5/6 classroom teachers reconceptualised curriculum to incorporate futures thinking as a result of ongoing professional learning and support. Through the use of analytical bracketing and post-analytic ethnomethodology for analysis across the data, the presenter proposes a conceptual model which highlights the complexity of this work as well as a theoretical explanation of why futures remains the missing dimension in education.

Optimal hedge ration with moving least squares - an empirical study using Indian single stock futures data

The use of commodity, currency and stock index futures to hedge risky exposures in the underlying assets is well documented in financial literature. However single stock futures are a relatively new addition to the family of futures and as such, academic research on its use as a hedging tool is relatively thin. In this study we have explored the efficacy of two different methodological approaches that may be applied when hedging a long position in the underlying stock with a single stock future. We use daily trading data covering years 2002 to 2007 from the Indian market, where single stock futures have been really thriving in terms of volume of trade, to extract the optimal hedge ratios using both static OLS as well as 30-day, 60-day and 90-day moving least squares. The method of moving least squares has been in use by market practitioners for some time primarily as a trend analysis and charting tool. Our results indicate that the moving least squares approach outperforms the static OLS in terms of the hedging efficiency, which has been measured by the root mean square hedging error.

What drives stock markets over short horizons? Evidence from emerging markets

The goal of this paper is to examine the importance of permanent and transitory shocks in explaining variations in stock prices for Singapore, Taiwan, and South Korea using a trend-cycle decomposition technique. This study is novel in that in measuring the impact of shocks we not only impose common trend restrictions but also common cycle restrictions. We later undertake a post-sample forecasting exercise to confirm the efficiency gains from imposing common cycle restrictions. We find that over short horizons, transitory shocks are the dominant source of variations in stock prices for South Korea, while permanent shocks explain the bulk of the variations in stock price of Singapore and Taiwan.

Volatility linkages and spillovers in stock and bond markets : some international evidence

This study investigates the transmission of market-wide volatility between the equity markets and bond markets of Japan, Germany, the U. K., and the U. S. To measure the volatility transmission, the BEKK- a decomposition approach to the multivariate GARCH (1,1) model, is used to examine the cross-market contemporaneous effect of information arrival. Our results suggest that within the domestic cross markets, the volatility transmission is undirectional from the stock market to the bond market. Evidence from international cross-market analysis is mixed, with strong evidence on volatility spillover among these international stock markets, but weak evidence between international stock and bond markets. In addition, there are significant bi-directional volatility transmissions between stock markets in Germany and the U. K., and between Germany and the U. S. The volatility transmissions among these markets suggest that the international diversification of bonds is not prevalent.

Volatility transmissions between stock and bond markets : evidence from Japan and the U.S.

This study attempts to investigate the transmission of market-wide volatility between the equity markets and bond markets of Japan and the U.S. To measure the volatility transmission, the BEKK (Baba, Engle, Kraft and Kroner, 1990) method, a decomposition approach of the multivariate GARCH (1,1) model, is used to examine the cross-market contemporaneous effect of information arrival. The time series analysis provides evidence to the long-run phenomena of causality in conditional variances of paired assets within the local and international markets. Within various pairings, some evidence of bi-directional volatility transmissions such as informational linkages have been observed. Our empirical results suggest that within the domestic cross markets, the volatility transmission is unidirectional from the stock market to the bond market. Evidence from international cross-market analysis is mixed, with strong evidence on volatility spillover among these international stock markets, but weak evidence between international stock and bond markets. In addition, there are significant directional volatility transmissions between DJI index and FTSE100 index, and between DJI index and DAX200 index. The volatility transmission between these two markets indicates that the international diversification of bonds is not prevalent.

Can the choice of interpolation method explain the difference between swap prices and futures prices?

The standard model linking the swap rate to the rates in a contemporaneous strip of futures interest rate contracts typically produces biased estimates of the swap rate. Institutional differences usually require some form of interpolation to be employed and may in principle explain this empirical result. Using Australian data, we find evidence consistent with this explanation and show that model performance is greatly improved if an alternative interpolation method is used. In doing so, we also provide the first published Australian evidence on the accuracy of the futures-based approach to pricing interest rate swaps.

Volatility transmission between stock and bond markets : evidence from US and Australia

This paper investigates the cross-market informational dependence between these assets under disparate interest rate conditions of the U.S and Australia. With conditional variance as a proxy for volatility, we use the BEKK – a matricular decomposition of the bivariate GARCH (1,1) model to examine the cross-market contemporaneous effect of information arrival. Applying the model to the stock and bond indices of both countries, we find evidence of volatility spillover, thereby supporting the notion of informational dependence between each market

Australian and US interest rate swap markets : comparison and linkages

We investigate and compare the determinants of US and Australian interest rate swap spreads and the linkages between these markets. The slope of the risk-free term structure is the most significant determinant and its importance is greater for longer terms to maturity. Interest rate levels and, in Australia, the default premium also have some impact. The influences of interest rate volatility, the liquidity premium and (in the USA) the default premium are small or negligible. We hypothesise, and our evidence confirms, that the US swap market significantly affects the Australian swap market but not vice-versa.

Efficiency, cointegration and contagion in equity markets : evidence from China, Japan and South Korea

This paper empirically examines whether three East Asian stock markets, namely, those of China, Japan and South Korea, are individually and/or jointly efficient, and whether contagion exists between the cointegrated markets. While individual market efficiency is examined through testing for the random walk hypothesis, joint market efficiency is examined through testing for cointegration and contagion. The present study finds that the hypothesis of individual market efficiency is strongly rejected for the Chinese stock market, but not for the Japanese and the South Korean stock markets. However, when testing for cointegration, market efficiency is strongly rejected for all these markets. We take a simple case of contagion and find that although there is a long-term relationship among the three markets, the contagion hypothesis cannot be rejected only between Japanese and South Korean stock markets, indicating short-run portfolio diversification benefits from these two markets.
