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...

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...

This paper analyses two features of concern to policy-makers in the countries of the prospective European Monetary Union: The solvency of their governments finances; and the accuracy of fiscal forecasts.

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...

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...

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...
