TL;DR: In this paper, the authors estimate the length-of-run elasticity of liquor by comparing state sales before and after price increases, standardized by states in which price did not change.
Abstract: Arc elasticity is estimated for liquor by simply comparing state sales before and after price increases, standardized by states in which price did not change. The technique can be used wherever there are several economic units independent with respect to price changes; it allows causal interpretation and it permits comparison of various length-of-run elasticities.
TL;DR: In this paper, a joint model of choice for both auto ownership and travel mode to work in Karachi, Pakistan is presented, which is based on stochastic utility maximization and is estimated utilizing nested logit techniques.
TL;DR: In this article, the effect of vertical integration by an input monopolist on the price of the final product and the derived demands are examined when the production is of CES and the demand for the final products is of constant elasticity.
Abstract: The effect of vertical integration by an input monopolist on the price of the final product and the derived demands are examined when the production is of CES and the demand for the final product is of constant elasticity. The results are proved by analytical methods. Specifically, when the elasticity of substitution is less than one, the price of the final product can decrease but, regardless of any conditions, the derived demand for the nonmonopolized input decreases. However, that of monopolized input decreases if and only if the elasticity of substitution exceeds the elasticity of demand.
TL;DR: This article showed that there is no direct or inverse relationship between the two concepts, if curvature of the isoquant is defined either in its strict mathematical sense or as the second derivative.
Abstract: This paper demonstrates that, contrary to deeply rooted beliefs, there is no link between curvature and the elasticity of substitution. We show that there is no direct, nor inverse, relationship between the two concepts, if curvature of the isoquant is defined either in its strict mathematical sense or as the isoquant's second derivative. We finally suggest to view the elasticity of substitution as an efficiency parameter.
