Human resource center concept: The A.T.&T. experience

There were many lessons learned in this experiment; among them: that change efforts must be systemwide and must be directed at those problems which represent the greatest barriers to change. While this project failed, the authors find and spell out the conditions in which it could have been an adequate vehicle.     

Bounding quantile demand functions using revealed preference inequalities

This paper develops a new approach to the estimation of consumer demand models with unobserved heterogeneity subject to revealed preference inequality restrictions. Particular attention is given to nonseparable heterogeneity. The inequality restrictions are used to identify bounds on counterfactual demand. A nonparametric estimator for these bounds is developed and asymptotic properties are derived. An empirical application using data from the UK Family Expenditure Survey illustrates the usefulness of the methods.
