We exploit the availability of active single-stock futures on India's National Stock Exchange (NSE) to provide estimates of overall informational efficiency, without conditioning on a public announcement. The key is the estimation of the primitive parameters of an asset pricing model with...

Energy conservation (EC) has been taken as basic state policy in China for more than 20 years and China achieves 3.9% annual energy saving from 1980 to 2005. In 2006 China Central Government firstly set up a binding target of reducing GDP energy intensity by 20% in its 11th Five-Year-Plan (FYP)....

Water hyacinth, as waste biomass, can potentially replace fossil fuels and address pressing issues of energy shortage and serious environmental pollution. In this study, microwave-assisted dilute acid pretreatment was proposed to enhance the enzymatic saccharification of water hyacinth for...

This paper analyzes a spurious regression involving AR(p) infinite-variance processes in the presence of structural breaks by least squares using asymptotic theory. It is found that when regressing two independent infinite-variance sequence with breaks in the level and slope of trend, no matter...

We estimate a translog production function based on data from a Japanese automobile plant in the Midwest where output is determined by capital and different supervisory time inputs. We fit a model which allows for heteroskedastic errors, where this heteroskedasticity is a function of various...

This paper assesses the importance of the role of prices as aggregators of private information in the S&P 500 future market. We estimate primitive parameters of the Hellwig (1980) noisy rational expectations model, when both prices and terminal values are observable. The variance-covariance...
