Les auteurs reexaminent l'evolution des betas des firmes apres les variations inattendues de dividende regulier sur les marches boursiers americain et canadien. Les resultats indiquent que l'estimation des betas par le modele de marche avec une modelisation de l'heterovariance des erreurs permet...

We establish the relationships between certain Bayesian and classical approaches to instrumental variable regression. We determine the form of priors that lead to posteriors for structural parameters that have similar properties as classical 2SLS and LIML and in doing so provide some new insight...

Five different identification problems in mixture models are made explicit. Necessary and sufficient relationships among these problems of identification are analyzed using the concepts of weak and strong identification. This analysis is first particularized under a normality assumption and then...

Alamar and Glantz interpret smoking in restaurants as a market failure, and they claim that restaurants should welcome government laws that disallow smoking in all restaurants. Contrary to their claims, restaurant owners do have an incentive to eliminate smoking if doing so raises the value of...

In the September 2007 critique of Alamar and Glantz, I argued that smoking in restaurants (and bars) does not constitute an externality and that Alamar and Glantz’s use of cross-sectional data to derive a price/sales ratio did not show us a meaningful picture of what happened before and...

“Smoking in Restaurants: Who Best Sets the House Rules?†by David Henderson, Econ Journal Watch 4(3), is a comment on our paper “Smokefree Laws Increase Restaurant Values,†Contemporary Economic Policy 22(4). Henderson asserts that restaurant owners can internalize all of the...

The market for models whose mathematical proofs are so lengthy and complex as to call for the delineation of intermediate steps with lemmas (Lemma 1, Lemma 2, etc.) expanded remarkably in prominent economic journals during the final four decades of the 20th century. However, Alfred Marshall,...

This paper makes a second reply to David R. Henderson, and concludes the exchange regarding the economics of smoke-free ordinances for restaurants.

The aim of this paper is to provide production elasticity estimates for the aggregate production functions of developing countries. We use aggregate data concerning the production sectors from two Middle Eastern countries. Unfortunately, the available data are quite of bad quality (small samples...

Due to increasing health consciousness and motivation to preserve environment for the next generations, more and more consumers are choosing ecological products. This research investigated the effects of university students’ environmental sensitivity and environmental behavior on their...
