چکیده
National accounts data provide the most comprehensive overview available of developments in national economies. They are of great interest to a wide range of users of economic information. These users, which include governments formulating budgetary policies, central banks making monetary policy decisions, businesses considering investment decisions and financial institutions making judgements concerning portfolio allocation, have needs which may differ in various respects. However, since their interest generally stems from the likelihood that they will make better decisions if they are well informed about economic developments, they all have a strong interest in the accuracy of national accounts statistics. This paper examines the reliability of preliminary quarterly national accounts statistics. In particular, it considers the longer-term behaviour of the provisional estimates to GDP growth and its main expenditure components through an examination of the revisions to those estimates. It covers the seven largest OECD countries and, as such, updates and extends upon previous OECD analysis on the topic. Overall, the results are broadly similar to the earlier work; that preliminary estimates for output growth have not been statistically biased, although the average size of revisions has been large but smaller than those exhibited by the demand components of GDP. Les données des comptes nationaux fournissent le résumé statistique disponible le plus complet sur les évolutions des économies nationales. Elles sont d'un grand intérêt pour une large gamme d'utilisateurs d'informations économiques. Ces utilisateurs, qu'ils soient des gouvernements formulant des politiques budgétaires, des banques centrales décidant des politiques monétaires, des entreprises étudiant les choix d'investissement ou des institutions financières prenant des décisions relatives à des choix de portefeuille, ont des besoins qui peuvent différer de diverses manières. Néanmoins, puisque leur intérêt provient généralement de la probabilité qu'ils pourront prendre de meilleures décisions s'ils sont bien informés au sujet des développements économiques, ils s'intéressent tous à l'exactitude des statistiques des comptes nationaux. Ce document examine la fiabilité des statistiques préliminaires des comptes nationaux trimestriels. En particulier, il étudie le comportement à long terme des estimations provisoires de la croissance du PIB et des principales composantes de la demande, en examinant les révisions opérées sur ces estimations. Il couvre les sept principaux pays de l'OCDE et ainsi, met à jour et prolonge les précédentes analyses de l'OCDE sur la question. Dans l'ensemble, les résultats sont d'une manière générale similaires aux précédents travaux, à savoir que les estimations préliminaires de la croissance de la production ne …

The Forecasting Performance of Various Models for Seasonality and Nonlinearity for Quarterly Industrial Production∗
Seasonality often accounts for the major part of quarterly or monthly movements in detrended macro-economic time series. In addition, business cycle nonlinearity is a prominent feature of many such series too. A forecaster can nowadays consider a wide variety of time series models which describe seasonal variation and regime-switching behaviour. In this paper we examine the forecasting performa...
