Models based on economic theory have serious problems forecasting exchange rates better than simple univariate driftless random walk models, especially at short horizons. Multivariate time series models suffer from the same problem. In this paper, we propose to forecast exchange rates with a...

The debate on the forecasting ability in economics of non-linear models has a long history, and the Great Recession provides us with an opportunity for a re-assessment of the forecasting performance of several classes of non-linear models, widely used in applied macroeconomic research. In this...

We propose a new approach to forecasting the term structure of interest rates, which allows to efficiently extract the information contained in a large panel of yields. In particular, we use a large Bayesian Vector Autoregression (BVAR) with an optimal amount of shrinkage towards univariate AR...

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...

The relationship between wages, prices, productivity, inflation and unemployment in Italy, Poland, and the UK between the 1960s and the early 1990s is modelled as a cointegrated vector autoregression subject to regime shifts. For each of these economies there is clear evidence of a change in the...

We analyse the relative performance of the IMF, OECD and EC in forecasting the government deficit, as a ratio to GDP, for the G7 countries. Interesting differences across countries emerge, sometimes supporting the hypothesis of an asymmetric loss function (i.e. of a preferrence for...

Models based on economic theory have serious problems at forecasting exchange rates better than simple univariate driftless random walk models, especially at short horizons. Multivariate time series models suffer from the same problem. In this paper, we propose to forecast exchange rates with a...

We suggest a simple non model based procedure to recover a time series from its temporally aggregated realizations. If additional assumptions on the under lying process are intorduced, it is shown that the procedure is related to many of the former proposals in the literature. It can also be...

We show how the use of panel data methods such as those proposed in single equations by Kao and Pedroni or in systems by Larsson and Lyhagen to investigate economic hypotheses such as purchading power pariety or the term structure of interest rates may be affected by the existence of cross-unit...
