Optimal Policy in OG Models

In the present paper general stationary overlapping generations economies with many commodities in every period and many different consumers in every generation are considered. A government maximizes a utilitarian social welfare function, which is the sum of weighted averages of utilities for generations, through fiscal policy, i.e., monetary transfers and taxes. Situations both with and withou...

A conjecture of Yves André . ∗

The introduction to [2] (and references contained therein) contains a comprehensive exposition of terminology and notations relative to this conjecture. Since we use the same terminology and notations, we do not reproduce them here. The introduction to [2] also contains an exposition of results on this conjecture obtained before the article [3] came out. In this article we prove the following t...

Reals which Compute Little André

We investigate combinatorial lowness properties of sets of natural numbers (reals). The real A is super-low if A′ ≤tt ∅′, and A is jump-traceable if the values of {e}A(e) can be effectively approximated in a sense to be specified. We investigate those properties, in particular showing that super-lowness and jump-traceability coincide within the r.e. sets but none of the properties implies the o...

Placebo. Historie, biologi og effekt

Since 1950 or so, placebos and their effect have generated a considerable interest in certain medical communities, in particular among psychiatrists and the designers of clinical trials, yet the only significant external study of this phenomenon to appear has been Howard Brody's doctoral investigation, Placebos and the philosophy ofmedicine, published in 1980. In 1997, however, three book-lengt...
