This paper examines a Waste Management Organisation's (WMO) pricing options to implement the Pareto-efficient allocation in an economy where materials are first extracted, then used for producing a consumption good and finally recycled or landfilled. The WMO is established by the producers who...

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...

This paper studies the market allocation in an economy where material is used for producing a consumption good, then recycled and finally landfilled, and where a recycling firm has market power. The material content constitutes an aspect of green product design and affects the recycling costs....

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...

In der vorliegenden Studie ueberpruefen wir verschiedene Gebuehrenstrategien der Dualen System Deutschland AG (DSD) darauf hin, ob sie die pareto-effiziente Allokation in der Abfallwirtschaft implementieren. Dabei greifen wir auf eine disaggregierte Modelloekonomie zurueck, in der Material...

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...

This paper focuses on the extraction of volatility of financial returns. The volatility process is modeled as a superposition of two autoregressive processes which represent the more persistent factor and the quickly mean-reverting factor. As the volatility is not observable, the logarithm of...

Fair representation of voters in a committee representing different voters' groups is being broadly discussed during last few years. Assuming we know what the fair representation is, there exists a problem of optimal quota: given a fair distribution of voting weights, how to set up voting rule...
