Comments on Edward Nelson, " the Future of Monetary Aggregates in Monetary Policy Analysis " 1

This is a very interesting paper about the role of money in monetary-policy analysis (Nelson (2003)). Ed Nelson is the ideal author of such a paper. He is a master of modern monetary economics, including New Keynesian analysis, being a student of Ben McCallum’s and a coauthor with Ben of some of the pioneering contributions to the New Keynesian literature. Ed is also a master of more traditiona...

Characterisations of Nelson Algebras

Nelson algebras arise naturally in algebraic logic as the algebraic models of Nelson’s constructive logic with strong negation. This note gives two characterisations of the variety of Nelson algebras up to term equivalence, together with a characterisation of the finite Nelson algebras up to polynomial equivalence. The results answer a question of Blok and Pigozzi and clarify some earlier work ...

Nelson–Aalen Estimator

The Nelson–Aalen estimator is a nonparametric estimator which may be used to estimate the cumulative hazard rate function from censored survival data (see Survival Distributions and Their Characteristics). Since no distributional assumptions are needed, one important use of the estimator is to check graphically the fit of parametric models, and this is the reason why it was originally introduce...
