This paper investigates the properties of four demand systems used to predict the effects of differentiated products mergers: the Almost Ideal Demand System (AIDS), logit, linear, and loglinear ...

This article presents a Monte Carlo evaluation of some alternative estimators for a demand model when the budget constraint is piecewise-linear and the budget set is convex. We examine the performance ...

Total factor productivity (TFP) is considered as a good measure of productivity. However, empirical TFP, often calculated from ordinary least squares (OLS) residuals from production function estimates ...
