The extant literature is split on the best measure of marginal cost in the New Keynesian Philips Curve, with the output gap and the labor share being the most commonly advocated proxy measures. Which one is the best measure? In this article, I assume that agents update their understanding and expectation period by period, a learning process. In terms of econometrics, I use a recursive Vector Au…
The transesterification of triacetin to methyl acetate catalyzed by 11 kinds of low boiling point amines was examined at subcritical methanol temperature as model reactions to simulate the biodiesel production. It was found that the branched amines showed higher yield of methyl acetate than normal amines. For normal amines, the yield of methyl acetate decreased with the increase of the carbo…
