The convergence hypothesis in growth theory implies that the frequency of the density distribution of GDP in a cross-section of countries tends to approach unimodality as we move forward in time. The convergence theory in a cross-section of 119 countries is tested by means of bootstrap...

One of the stylized facts of unemployment is that shifts in its mean rate between decades and half-decades account for most of its variance. In this paper, the authors use a statistical analysis based on switching regression models and nonparametric density estimation techniques to identify the...

This paper considers the role of international openness in facilitating the convergence of average income per capita between countries. The statistical technique of Discriminant Analysis is used to sort economies into groups of open and closed on the basis of a number of measures of the stance...

This paper extends US evidence on the ability of current dividend yields to predict future equity returns in the G5 countries. By using non-parametric methods, evidence of a similar non- linear structure is found in all the countries analysed. This casts doubt on the linear framework adopted in...

Granger causality tests are widely used in applied economics as a way of establishing if a variable has been a leading indicator of another over the past. However, like most statistical tests, Granger causality tests require that the relationship between the variables remains stable over the...

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...

This paper analyses a number of methods for trend estimation focusing on their ability to pick up turning points quickly at the end of a series. An application to the Bank of England flows M4 series is provided which shows that some of the proposed methods may be more reliable than others for...

One of the stylized facts of unemployment is that shifts in its mean rate between decades and half-decades account for most of its variance. In this paper, we use a statistical analysis based on Markov switching regression models to identify the dates of infrequent changes in the mean of the...
