Semi-parametric
Spatial Auto-covariance Models of Regional Growth Behaviour in Europe
(PDF)
Co-authored with Roberto Basile, ISAE.
In this paper we use the regression approach to examine the growth
behaviour of European regions in the period 1988-2000. We claim that
the traditional neoclassical approach proposed by Barro and
Sala-i-Martin (1991, 1992) and implemented by Mankiw, Romer and Weil
(1992) for the analysis of countries’ growth behaviour cannot
automatically be applied at the regional scale in Europe, since it does
not consider the effects of labour market imperfection and does not
take account of the presence of spatial dependence and of
non-linearities (or multiple regimes) in growth behaviour. Thus, we
propose a semi-parametric spatial auto-covariance model of regional
growth behaviour in Europe which simultaneously controls for the effect
of unemployment and takes account of the problems of non-linearities
and spatial dependence.

Fuzzy-ish Model of Learning and Forgetting in Consumer Choice

Introduces a framework for incorporating dynamic updating of the
consumer's preference ordering that can mimic learning and forgetting
behaviour. Uses methods similar to those used in fuzzy logic.
