This paper investigates the efficiency of the gold market with respect to the information contained in sequences of successive price changes. Tests for serial correlation and modelling the changes as first-order Markov processes indicate some short-term dependence. While there is no reason to believe outsiders can profit from knowledge of these relationships, insiders might, though this is not certain. In addition, the application of a market model to monthly returns for the period 1974–1977 results in the finding that gold's ‘alpha’ and ‘beta’ were positive, but not significantly different from zero. 相似文献

This study empirically investigates the recent SFAS No. 33 requirements to determine if the inflation disclosures, or information similar to it, are impounded in security returns. An attempt is also made to determine which of the two diverse disclosures best represent the information impomded by the market. The investigation utilizes a methodological framework arising out of currently accepted asset pricing theory. The results suggest that the current cost data parallels the information impounded in security returns and that it provides risk information not included in the commonly employed systematic risk factor, beta. 相似文献

The demographic assumptions and outcomes in the three successive Intergenerational Reports have differed enormously. This has brought a degree of derision upon the production of these reports in the serious press. Furthermore, the Intergenerational Reports’ projections of labour force participation rates have proven to be very wrong in the short term. The fourth Intergenerational Report will need to address this credibility gap. This article analyses the reasons that the Intergenerational Reports’ projections have been wide of the mark and makes suggestions about future approaches. 相似文献

Abstract The subject of this paper is the repeat use of UI/EI benefits in Canada. The first objective is to investigate empirically the pattern of adjustment that UI users exhibit over a multiple claim horizon. Our secondary objective is to investigate a behavioural channel that might potentially underlie observed adjustment effects, namely, individual learning effects. We estimate an econometric model of how certain features of their claims change as they file subsequent claims. We find strong empirical patterns suggesting that there does appear to be some sort of an adjustment process; beneficiaries tend to approach a desired value for these particular facets of their UI claims. There appears to be some process of growing sophistication of UI use – which some might label ‘gaming the system’– reflecting the adjustment of claims and the concomitant employment patterns to the provisions and rules of the regime. We also uncover evidence in favour of the existence of individual learning effects. 相似文献

ABSTRACTThe benefits of biofuels depend on the feedstock, conversion pathway and local context. This paper assesses biofuels technology readiness and developments to provide foresight to biofuels development in Southern Africa. Efficient conversion pathways, coupled with biomass from waste or high-yielding energy crops, will reduce both the costs of biofuels production, and the environmental impacts. Compared to petroleum fuels, the current commercial biofuels (ethanol, biogas and biodiesel) typically offer carbon emission reductions of 30–50% but are marginally more expensive. The extent of biofuels market penetration will therefore be influenced by mandates (blending targets) and subsidies (green premium). Advanced biofuels promise greater efficiencies and carbon emission reductions at reduced cost but will require further research and development to reach commercialisation. If developed appropriately, biofuels can reduce carbon emissions and improve energy security, while enabling sustainable agriculture and improved natural resources management. 相似文献

We document a negative impact of realistic trading timing on trend-following profits, across an international sample of equity indexes and stocks. The discount effect is substantial but reduces as trend signals become less accurate. The size of this trading timing bias is largely driven by the volatility of buy-and-hold returns and that of trend signals. 相似文献

This study proposes methodological adjustments to the widely adopted performance benchmarking methodology of Daniel et al. (1997 ) as a means of improving the precision of alpha measurement for active equity fund managers. We achieve this by considering the monthly updating of characteristic benchmarks and to ensure neutrality to the Standard & Poor's/Australian Stock Exchange 300 index. Applying this benchmark to a representative sample of active Australian equity funds and simulated passive portfolios that mimic fund manager‐style characteristics, we find statistically different and lower tracking error compared with using the standard characteristic benchmark methodology. We also find evidence that the modified benchmark statistically infers an alpha closer to zero compared with the standard benchmark methodology. Our findings suggest that improved specifications of characteristic benchmarks represent better methods in quantifying fund manager skill. 相似文献
