Many econometric problems can benefit from the application of parallel computing techniques, and recent advances in hardware and software have made such application feasible. There are a number of freely available software libraries that make it possible to write message passing parallel...

Although there are encouraging trends, alcohol abuse continues to be a significant public health problem. Econometric studies of alcohol demand have yielded a great deal of information for alcohol abuse prevention policy. These studies suggest that higher alcohol taxes and stricter drunk-driving...

A trend estimated from an unobserved components model tends to be smoother when it is modelled as an integrated random walk rather than a random walk with drift. This article derives a test of the null hypothesis that the trend is deterministic against the alternative that it is an integrated...

In this paper, an empirically stable money demand model for M3 in the euro area is constructed. Starting with a multivariate system, three cointegrating relationships with economic content are found: (i) the spread between the long-term and the short-term nominal interest rates, (ii) the...

The relationships between real wages, output per capita, inflation and unemployment in Italy between 1970 and 1994 are modelled using a cointegrated vector autoregression. There is evidence of a change in the underlying equilibria and in the dynamic evolution of the variables, probably...

This paper is concerned with the stability of macroeconomic models in which there is no long-run trade-off between unemployment and inflation, because of a wage adjustment equation based on the NAIRU concept. It is shown, for a simple theoretical model and for the Bergstrom-Nowman-Wymer...

UK inflation has varied greatly in response to many economic policy and exchange-rate regime shifts, two world wars and two oil crises, as well as legislative and technological changes. Inflation is modelled as responding to excess demands from all sectors of the economy: goods and services,...

Recent work by the author on methods of spatial density analysis for time series data with stochastic trends is reviewed. The methods are extended to include processes with deterministic trends, formulae for the mean spatial density are given, and the limits of sample moments of non-stationary...

This paper studies the joint dynamics of U.S. output and unemployment rate in a non-linear VAR model. The non-linearity is introduced through a feedback variable that endogenously augments the output lags of the VAR in recessionary phases. Sufficient conditions for the ergodicity of the model,...
