In this paper we present a simple model where asset returns are functions of multiple investment growth rates. The model is tested for its ability to price the 25 Fama-French portfolios using the Generalized Methods of Moments (GMM) methodology, as well as Fama-MacBeth cross-sectional...

International test scores are used to proxy the quality of source country educational outcomes and explain differences in the rate of return to schooling among immigrants in Canada. The average quality of educational outcomes in an immigrant’s source country and the rate of return to...

A critical step in group sequential designs is computation of the appropriate critical values for rejecting H0 at the interim look to keep the overall type I error rate at a prespecified level. When applying the sequential test in a study with an equivalence hypothesis, calculation of the...

This procedure specifies production area environment, production technology, prevention and control of plant diseases and insect pests, and production files of pollution-free foods by taking tomato as an example. This procedure is applicable for greenhouse production of pollution-free food in...

Biodiesel has become attractive as an alternative renewable fuel, but its large-scale production has been restricted because of the high cost of feedstock. Therefore, alternative feedstock is urgently needed to enable biodiesel production from cheap raw materials. Toward this goal, a...

The textile and clothing industry generates much pollution and consumes a large amount of resources. Improper uses and disposal of clothing products make the problems much more severe. Fast fashion products shorten the valid lifecycle and generate more waste than regular clothing products....

Biodiesel has been considered as one of the promising non-fossil fuels, but its development also have promoted a drastic debate due to its current production status, such as oilseeds dependency, arable land requirement, high cost and long-term impact on food prices. Therefore alternative...

Biodiesel is a promising alternative diesel fuel which has increased worldwide public interest in a number of countries including China. But the high cost of producing biodiesel from feedstock, predominately food grade oils, limited its economic feasibility. An alternative of using grease...
