On ordinal utility, cardinal utility, and random utility
Though the Random Utility Model (RUM) was conceived
entirely in terms of ordinal utility, the apparatus throughwhich it is widely practised exhibits properties of
cardinal utility. The adoption of cardinal utility as a
working operation of ordinal is perfectly valid, provided
interpretations drawn from that operation remain faithful
to ordinal utility. The paper considers whether the latterrequirement holds true for several measurements commonly
derived from RUM. In particular it is found that
measurements of consumer surplus change may depart from
ordinal utility, and exploit the cardinality inherent in
the practical apparatus.
Holography for Cosmology
We propose a holographic description of four-dimensional single-scalar
inflationary universes, and show how cosmological observables, such as the
primordial power spectrum, are encoded in the correlation functions of a
three-dimensional QFT. The holographic description correctly reproduces
standard inflationary predictions in the limit where a perturbative
quantization of fluctuations is justified. In the opposite limit, wherein
gravity is strongly coupled at early times, we propose a holographic
description in terms of perturbative large N QFT. Initiating a holographic
phenomenological approach, we show that models containing only two parameters,
N and a dimensionful coupling constant, are capable of satisfying the current
observational constraints.Comment: 5 pages; new figure displaying predicted spectral running
