We investigate, in a model-independent way, the conditions required to obtain a satisfactory model of extended in ation in which in ation is brought to an end by a rst-order phase transition. The constraints are that the correct present strength of the gravitational coupling is obtained, that the present theory of gravity is satisfactorily close to general relativity, that the perturbation spec...

The paper examines the e¤ect of in‡ation on growth in transition countries. It presents panel data evidence for 13 transition countries over the 1990-2003 period; it uses a …xed e¤ects, full-information maximum likelihood, panel approach to account for possible bias from correlations among the unobserved e¤ects and the observed country heterogeniety. The results …nd a strong, robust, negative e...

This paper proposes a di¤erent empirical approach to estimate the UIP by analyzing a large number of cross-country bilateral exchange rates using cross-section analysis. Di¤erent from conventional time-series UIP, cross-sectional UIP is examined with single equation estimation and panel regression model estimation. The exchange rates analyzed here include a broad spectrum of countries: develope...

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 ...

Conventional wisdom is that in‡ation makes people spend their money faster, trying to get rid of it like a “hot potato.” Intuitively, this is one channel through which in‡ation increases velocity in theory (as in the data). Search-based monetary models seem ideal for studying this phenomenon. However, in the standard model, in‡ation acts like a tax, lowering the surplus associated with monetary...

The paper examines the transmission mechanism of monetary policy in an open economy with and without a binding zero bound on nominal interest rates. In particular, a foolproof way of escaping from a liquidity trap is suggested, consisting of a price-level target path, a devaluation of the currency and a temporary exchange rate peg, which is later abandoned in favor of price-level or in‡ation ta...

The pinna, or ex ternal ear, has been shown experim entally to perform an acoustical tran sfo r­ m ation essential to localization in hum an hearing. The m athem atical form of th e tran sfo rm a­ tion is given, the inverse to the transform ation is shown to exist, and a theory of localization constructed from the evidence. The theory is extended to reverberation and o ther facets of hum an hea...

Context-aware systems use sensors in order to analyse their environment and to adapt their behaviour. We have designed and developed Sens-ation, an open and generic service-oriented platform, which provides powerful, yet easy-to-use, tools to software developers who want to develop context-aware, sensor-based infrastructures. The service-oriented paradigm of Sens-ation enables standardised comm...
