Il ruolo della politica economica all'interno di un sistema economico, ed in particolare la capacità o meno da parte di questa di esercitare un'influenza attiva, efficace e duratura sulla dinamica delle principali variabili macroeconomiche, è sempre stato un tema al centro dell'attenzione e...

The paper presents a nonparametric approach, based on kernel density estimators, to assess and compare persistence of output fluctuations in Belgium, Canada, France, Germany, Italy, Japan, the United Kingdom and the Unated States. The results obtained are interpreted to be compatible in general...

In this paper we simulate a series which is segmented trend plus noise. Despite the imposed data generating process, usual tests for unit roots and estimates of persistence fail to reject the random walk hypothesis.

A procedure based on density estimation is suggested in the paper to discriminate trend stationary processes about local linear time trends from difference stationary processes. A 'rule of thumb' is constructed to detect the suitability of a segmented trend representation, and a regression...

This paper estimates the probability distribution of relative county unemployment in Britain for the years 1981-1995. We find that the distribution is unimodal in all years, with a falling variance between 1989 and 1994. We use bootstrap methods to determine critical values for the two tails of...
