Jürgen Bierbaumer-Polly, Sandra Bilek-Steindl, Marcus Scheiblecker, Nowcasting Economic Activity Using Large-Scale Dynamic Factor Models with Regional Block-Structure. An Application for the Austrian Economy

Reports (work in progress), January 2018
We propose a hierarchical four-level dynamic factor model (DFM) for now- and forecasting the quarterly Austrian GDP. In the model, the business cycle dynamics are defined not only by common, but also by block and subblock specific factors. These factors are related to domestic versus international data origin, as well as to characteristics according to Austria's regional structure (manufacturing vs. services dominated). While the dynamics in the national GDP growth are mainly determined by common shocks, a considerable part of the variation in the regional data can be explained by the subblock specific factors. In a "pseudo" real-time forecasting exercise we show that our proposed model outperforms a standard two-level DFM. To deal with missing observations at the beginning/end of the dataset we apply the expectation maximisation (EM) procedure to obtain a balanced data panel. The outcome of this are, i.a., backcasts of the quarterly Austrian GDP series which seem to fit the real-time estimates reasonably well. In a real-time setting, this backcast can give an early (approximately t+15 days) indication of quarterly GDP growth, with its first official release (Flash estimates) published at t+30.

Sandra Bilek-Steindl, Christian Glocker, Serguei Kaniovski, Thomas Url, Österreich 2025 – Einfluss der Bildungsstruktur auf das langfristige Wirtschaftswachstum

WIFO-Monatsberichte, 2017, 90(6), pp.479-491
   
Ein qualitativ hochwertiger Arbeitseinsatz erhöht nicht nur die Innovationskraft einer Volkswirtschaft, sondern verbessert auch deren Fähigkeit, technologische Innovationen aus dem Ausland nutzbringend einzusetzen. Erstmals schätzt die vorliegende Arbeit einen qualifikationsgewichteten Arbeitseinsatz für Österreich, indem das in Stunden gemessene Arbeitsvolumen mit bildungsspezifischen Informationen verknüpft wird. Wie eine einfache Wachstumszerlegung zeigt, erhöht die Berücksichtigung von qualifikationssteigernden Effekten im Arbeitseinsatz den Wachstumsbeitrag des Faktors Arbeit auf das Drei- bis Vierfache. So kann ein Teil des Wirtschaftswachstums erklärt werden, welcher bisher der Restgröße "totale Faktorproduktivität" zugeordnet wurde.

A revival in global industrial activity is spreading from East Asia, intensified by the recovery in Russia and Brazil. It noticeably benefits Austrian exports and industrial production. Leading indicators suggest that the positive development will continue. Both national and international sentiment indicators have reached peaks not seen in several years.
