Measurability of utility (or welfare)

Bentham or Bergson? Finite Sensibility, Utility Functions and Social Welfare Functions

Concavity of Utility, Concavity of Welfare, and Redistribution of Income

The marginal social value of income redistribution is understood to depend on both the concavity of individuals’ utility functions and the concavity of the social welfare function. In the pertinent literatures, notably on optimal income taxation and on normative inequality measurement, it seems to be accepted that the role of these two sources of concavity is symmetric with regard to the social...

Models of Cohen measurability

We show that in contrast with the Cohen version of Solovay’s model, it is consistent for the continuum to be Cohen-measurable and for every function to be continuous on a non-meagre set.

Measurability Properties of Spectra

We study Borel measurability of the spectrum in topological algebras. We give some equivalences of the various properties, show that the spectrum in a Banach algebra is continuous on a dense Gs, and prove that in a Polish algebra the set of invertible elements is an FaS and the inverse mapping is a Borel function of the second class. This article has its origin in the papers [7] and [5]. We stu...

Crisis of Public Utility Deregulation and the Unrecognized Welfare State

Successful achievement of public policies requires satisfaction of conditions affecting political feasibility for policy adoption and maintenance as well as economic viability of the desired activity or enterprise. Fulfilling these joint requirements when pursuing deregulatory policies for public utility industries in the U.S. is particularly difficult given the legacy of the common law doctrin...
