To answer the question "How to be an Ecological Economist", we must start by defining the field of Ecological Economics. Mainstream Economics altogether lacks the concepts required to deal adequately with nature, justice and time. It was the absence of these three concepts in this otherwise...

Least-Unmatched Price Auctions have become a popular format of TV and radio shows. Increasingly, they are also applied in internet trading. In these auctions the lowest single (unique) bid wins. We analyze the game-theoretic solution of least unmatched price auctions when prize, bidding cost and...

The long-run evolution of per-capita income exhibits a structural break often associated with the Industrial Revolution. We follow Mokyr (2002) and embed the idea that this structural break reflects a regime switch in the evolution of technological knowledge into a dynamic framework, using Airy...

In John Nash’s proofs for the existence of (Nash) equilibria based on Brouwer’s theorem, an iteration mapping is used. A continuous- time analogue of the same mapping has been studied even earlier by Brown and von Neumann. This differential equation has recently been suggested as a plausible...

We present a non-technical account of ambiguity in strategic games and show how it may be applied to economics and social sciences. Optimistic and pessimistic responses to ambiguity are formally modelled. We show that pessimism has the effect of increasing (decreasing) equilibrium prices under...

Diese Schrift behandelt ordnungs- und institutionenökonomische Aspekte des Systemwandels im allgemeinen sowie die monetäre Transformation im besonderen. Das auf dem Washington Consensus beruhende wirtschaftspolitische Standardkonzept und dessen Theoriedefizite werden hinterfragt und um...

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor...

A well-known result by Vega-Redondo implies that in symmetric Cournot oligopoly, imitation leads to the Walrasian outcome where price equals marginal cost. In this paper we show that this result is not robust to the slightest asymmetry in fixed costs. Instead of obtaining the Walrasian outcome...

The paper compares decision-making on the centralisation of public goods provision in the presence of regional externalities under representative and direct democratic institutions. A model with two regions, two public goods and regional spillovers is developed in which uncertainty over the true...

In den letzten drei Jahrhunderten ist die Wirtschaft in vielen Ländern - langfristig gesehen - dauernd gewachsen. Materieller Mangel ist in den entwickelten Ländern weitgehend verschwunden. Für die Erkenntnis der Leistungsfähigkeit der Marktwirtschaft wie der Defizite der sozialistischen...
