We provide a simple theory of in‡ation inertia in a staggered price setting framework a la Calvo (1983). Contrary to Calvo’s formulation, the frequency of price changes is allowed to vary according to an evolutionary criterion. Inertia is the direct result of gradual adjustment in this frequency following a permanent change in the rate of money growth.

This paper studies the logical modelling of presumptions and their effects on the burden of proof. Presumptions are modelled as default rules and their effect on the burden of proof is defined in terms of a distinction between the burden of production, the burden of persuasion and the tactical burden of proof. These notions are logically characterised in such a way that presumptions enable a pa...

Ataxia is a neurological symptom characterized by abnormal movement, due to cerebellar malfunction. Although the cause of the malfunction varies, from mutations in calcium or potassium channels to progressive degeneration of cerebellar tissue, the neurological symptoms of cerebellar-related ataxia are similar. In this short review we present a model that portrays the olivo-cerebellar system as ...

Neutrino Helioseismology

The observed deficit of B solar neutrinos may call for an improved standard model of the sun or an expanded standard model of particle physics (e.g., with neutrino masses and mixing). In the former case, contemporary fluid motions and thermal fluctuations in the sun’s core may modify nuclear reaction rates and restore agreement. To test this notion, we propose a search for short–term variations...
