In der Aussenhandelstheorie wird das Angebot und die Nachfrage mit Hilfe der Dualitaetstheorie abgebildet. Dabei wird auf nationaler Ebene das Problem der Erloesmaximierung untersucht, wobei die nationalen Faktorbestaende und die Produktionstechnologien der einzelnen Unternehmen gegeben sind....

Under the assumption of imperfect competition in a durable good industry, the present paper investigates the efficient regulation of solid waste which causes environmental damage at the end of the product's life. It turns out that the second-best waste tax falls short of the marginal...

This paper considers the implications of adding capital as a factor of production in a stochastic DGE model with sticky prices. Particular attention is given to the role of money demand and to the form of the utility function. I consider cash-in-advance- (CIA) as well as...

This paper examines the role of habit persistence in consumption in explaining persistent responses of inflation and output to money growth shocks. A monetary stochastic dynamic general equilibrium (DGE) model with a money-in-the-utility-function (MIU-) setup is augmented by habit formation in...

Recently macroeconomists have intensified their efforts to develop models that are able to generate persistent reactions of real variables to monetary shocks in stochastic DGE models with nominal rigidities. This has proven to be quite difficult in models with price staggering only. Most papers...

It is argued that due to their general instability dynamic optimization models cannot be used as positive theories of economic growth. The argument is substantiated by (numerical) examples. A simple rule of thumb is provided as an alternative to the RKC model. This rule is shown to perform well...
