Abstract: "In dieser Studie spezifizieren und schätzen wir ein strukturelles Modell von Mehrproduktunternehmen in der Halbleiterindustrie. Zusätzlich berücksichtigen wir explizit die Dynamik über den Produktlebenszyklus. Unsere Ergebnisse zeigen, daß diese beiden Aspekte gravierende Auswirkungen besitzen. Wir zeigen, daß (1) Spillovers und Skalenerträge für Mehrproduktunternehmen geringer sind als für Einzelproduktunternehmen, wogegen Lerneffekte geringfügig größer ausfallen. Unsere Ergebnisse bestätigen auch, daß Unternehmen eine intertemporale Outputstrategie verfolgen. Weiterhin wird gezeigt, daß sich Mehrproduktunternehmen im perfekten Wettbewerb befinden, wobei sich Einzelproduktunternehmen ähnlich wie Cournot Spieler verhalten. Wir zeigen, daß (2) Lerneffekte, Skalenerträge und Spillovereffekte über den Produktlebenszyklus variieren. Lerneffekte sind am Ende des Produktlebenszyklus größer, wenn neue Produkttechnologien entwickelt werden. Skalenerträge sind zunehmend und nehmen für Mehr
