A Note on Pure Variations of Axioms of Blackwell Determinacy
In this note, we look at weaker versions of the Axiom of Blackwell Determinacy introduced in [Lö02b] and [Lö03]. We use these results to get a new lower bound for the consistency strength of the Axiom of pure Blackwell Determinacy pBl-AD. We shall investigate Blackwell games against opponents with arbitrary mixed strategies Bl-Det(Γ), against opponents with usual pure strategies pBl-Det(Γ), and...
متن کاملDeterminacy for Measures
For a given finite positive measure we determine the minimal information that is needed from its Fourier transform to determine the measure completely. In particular, we show that if the support of a measure doesn’t contain a sequence of Beurling-Malliavin interior density d > 0 then the interval of determinacy for this measure must be of length larger than πd. As a consequence, we provide a sh...
متن کاملA note on welfare measures
I show that the “consumption variation” approach, commonly used in infinitely lived agent models to measure the welfare impact of a policy, is not accurate in overlapping generations environments. While in an infinitely lived agent environment the consumption variation can be shown to be equivalent to a measure based on the Hicks compensation principle, this is not true in overlapping generatio...
متن کاملA Note on Invariant Measures
The aim of the paper is to show that if F is a family of continuous transformations of a nonempty compact Hausdorff space Ω, then there is no F-invariant probabilistic regular Borel measures on Ω iff there are φ1, . . . , φp ∈ F (for some p ≥ 2) and a continuous function u : Ω → R such that P σ∈Sp u(xσ(1), . . . , xσ(p)) = 0 and lim infn→∞ 1 n Pn−1 k=0 (u ◦ Φ )(x1, . . . , xp) ≥ 1 for each x1, ...
متن کاملA Note on Measures of Parallel Sets
The r-parallel set to a set A in a Euclidean space consists of all points with distance at most r from A. We clarify the relation between the volume and the surface area of parallel sets and study the asymptotic behaviour of both quantities as r tends to 0. We show, for instance, that in general, the existence of a (suitably rescaled) limit of the surface area implies the existence of the corre...
