On the Quanti ation of Relevant Information

In ation during oscillations of the in aton

Damour and Mukhanov have recently devised circumstances in which in ation may continue during the oscillatory phase which ensues once the in aton eld reaches the minimum of its potential. We con rm the existence of this phenomenon by numerical integration. In such circumstances the quanti cation of the amount of in ation requires particular care. We use a de nition based on the decrease of the ...

Relative Price Distortions and Inflation Persistence

Sticky-price models often suggest that relative price distortion is a major cost of in‡ation. We provide an intuition for this: Even at low rates, in‡ation strongly a¤ects price dispersion which in turn has an impact on the economy qualitatively similar to, and of the order of magnitude of, a negative shift in productivity. The utility cost of price dispersion is quanti…ed and its impact on opt...

A fragment of se ond-order lambda al ulus (System F) is de ned that hara terizes the elementary re ursive fun tions. Type quanti ation is restri ted to be non-interleaved and strati ed, i.e., the types are assigned levels, and a quanti ed variable an only be instantiated by a type of smaller level, with a slightly liberalized treatment of the level zero.

General information in relevant logic

This paper sets out a philosophical interpretation of the model theory in Mares and Goldblatt “An Alternative Semantics for Quanti…ed Relevant Logic” (The Journal of Symbolic Logic 71 (2006)). This interpretation distinguishes between truth conditions and information conditions. Whereas the usual Tarskian truth condition holds for universally quanti…ed statements, their information condition is...
