This paper sets out to investigate the role of additive uncertainty under plausible non-standard central bank loss functions over future inflation. Building on a substantial body of evidence in the economic psychology literature, this paper postulates (i) period-by-period loss functions that are...

In a seminal paper, Becker (1968) showed that the most efficient way to deter crime is to impose the severest possible penalty (to maintain adequate deterrence) with the lowest possible probability (to economize on costs of enforcement). We shall call this the Becker proposition (BP). The BP is...

A critical element in all discounted utility models is the specification of a discount function. We introduce three functions: the delay, speedup and generating functions. Each can be uniquely elicited from behaviour. The delay function determines stationary and the common difference effect. The...

A critical element in all discounted utility models is the specification of a discount function. We extend the standard model to allow for reference points for both out- comes and time. We consider the axiomatic foundations and properties of two main classes of discount functions. The first, the...

Standard equilibrium concepts in game theory find it difficult to explain the empirical evidence in a large number of static games such as prisoners’ dilemma, voting, public goods, oligopoly, etc. Under uncertainty about what others will do in one-shot games of complete and incomplete...

We consider a discounted utility model that has two components. (1) The instan- taneous utility is of the prospect theory form, thus, allowing for reference dependent outcomes. (2) The discount function embodies a ‘reference time’ to which all future outcomes are discounted back to, hence,...

With nondistortionary user charges, the first best and second best of a single-club-exogenous-income economy with identical individuals coincide. They differ if incomes differ. Overprovision of a superior club good then occurs in the Second Best.

The neglect of administrative issues is a serious limitation of optimal tax theory, with implications for its practical applicability. We focus on an important class of administrative problems, namely that the tax bases are measured with some error. We also consider the full set of tax...
