Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

Die Wirtschafts- und Finanzkrise wirkt wie ein externer Schock auf die deutsche Konjunktur.Mit zwei makroökonomischen Simulationsmodellen weisen die Autoren nach, dass die Krise in Deutschland allein auf diesen Schock zurückzuführen ist. Die Exportabhängigkeit der Wirtschaft führt dazu,...

Strengthening potential output is high on the agenda for economic policy in the European Union. While there is widespread agreement that structural policies have a positive impact on long-term growth, there is a controversial discussion whether coordination of macroeconomic policies can...

In particular, the paper focuses...

This paper uses a structurally estimated macroeconometric model, denoted the MC model, to evaluate inflation targeting in the United States. Various interest rate rules are tried with differing weights on inflation and output, and various optimal control problems are solved using differing...

To provide an modelling strategy with transparent and theoretically coherent foundation has been one of the targets of the paper by Garratt, Lee, Pesaran and Shin. They develop a core model for a small open economy based production technology, arbitrage conditions, flow identities and long-run...

In this study of Ghana integrated to the world economy, we focus primarily on Ghana-UK-Germany trade axis partly because of Ghana's relative dependence on the EU for her international trade. The study employs „representative“ country macroeconometric models of these economies, using data...

Es wird das Konzept für ein makroökonomisches Strukturmodell mit integriertem Innovationsprozesskern zur Analyse und Projektion der Wirtschaftsentwicklung in Deutschland vorgestellt. Das geplante Modell soll explizit die Auswirkungen des immer bedeutsamer werdenden IuK-technologischen...

Cyclically induced changes in taxes and government expenditures which tend to stabilise aggregate output are called automatic stabilisers. Using a small macro model, this paper reviews alternative methods of measuring the smoothing power of automatic stabilisers and discusses their relationship...

Das System der Volkswirtschaftlichen Gesamtrechnungen (VGR) in Deutschland wurde im Frühjahr 2005 von der Festpreisbasis auf das Vorjahrespreiskonzept (Kettenindexkonzept) umgestellt. Dadurch werden Substitutionseffekte besser berücksichtigt und die periodische Umbasierung der Zeitreihen...
