We show several results about uni ation problems in the equational theory ACUNh onsisting of the theory of ex lusive or with one homomorphism. These results are shown using only te hniques of automata and ombinations of uni ation problems. We show how to onstru t a most-general uni er for ...

Eurosystem …nally published its eagerly awaited in ‡ation forecast (as well as a forecast of GDP growth). It did so after having been provoked and prodded to do so, by the European Parlia-ment's Committee on Economic and Monetary A¤airs and a large number of external observers and commentators, since the announcement of the Eurosystem monetary-policy strategy in the fall of 1998. This Brie…ng P...

In this paper we simulate a central bank subject to the misperception that prices are indexed to past in‡ation in periods when …rms are unable to re-optimise. It thinks, in other words, that in‡ation is intrinsically persistent. The central bank sets monetary policy optimally subject to this belief. The central bank updates its beliefs about indexation using a constant gain learning scheme. The...

The biochemical role of poly(ADP-ribosyl)ation on internucleosomal DNA fragmentation associated with apoptosis was investigated in HL 60 human premyelocytic leukemia cells. It was found that UV light and chemotherapeutic drugs including adriamycin, mitomycin C, and cisplatin increased poly(ADP-ribosyl)ation of nuclear proteins, particularly histone H1. A poly(ADP-ribose) polymerase inhibitor, 3...

The paper by Jonas and Mishkin does a very good job of describing the history, the implementation, and the e®ects of in°ation targeting in Central Europe. The description is rich and informative, showing the inconsistencies and the adjustments in monetary policy over time, the con°icts between monetary and ̄scal policy, and the di±culty of achieving in°ation targets. The basic conclusion, which ...

Abstract We study the weak convergence order of two Euler-type discretizations log-Heston model where we use symmetrization and absorption, respectively, to prevent discretization underlying CIR process from becoming negative. If Feller index $\nu $ satisfies $\nu>1$, establish 1 $, while for \leq 1$, obtain -\epsilon $\epsilon>0$ arbitrarily small. illustrate our theoretical find...

Les maîtrises (ou masters) en recherche design permettent aux étudiant·e·s de se spécialiser explorant un objet d’étude leur choix avec une formation axée sur démarche scientifique. À partir d’une étude cas la maîtrise mémoire (MDM) à l’École l’Université Laval, il appert qu’une certaine con...

The ECB and the Eurosystem should normally take asset-price movements and potential asset-price bubbles into account only to the extent these are deemed to have an impact on the in‡ation and output-gap forecasts that should guide monetary policy. Asset prices should not be separate target variables, additional to in‡ation and the output gap. The explicit or implicit objective of …nancial stabil...
