Sommario/riassunto |
|
Antizyklische Regelmechanismen für den Staatssektor («formula flexibility») werden mit diskretionärer staatlicher Konjunkturpolitik verglichen. Damit wird der häufig anzutreffende Vergleich vermieden, bei dem die kontroversen Strategien sich ausserdem durch die Zielsetzung unterscheiden oder mit unterschiedlichen Annahmen über die Funktionsmechanismen der Wirtschaft konfrontiert werden. Sowohl theoretische Überlegungen als auch anhand empirischer Beispiele belegte Ergebnisse (Indikatorvorschläge aus den USA, Gesamtindikator des Sachverständigenrats und Bestersscher Indikatorvorschlag aus der BRD) lassen «formula flexibility» als völlig ungeeignet zur Lösung konjunkturpolitischer Probleme erscheinen. |
