Models with heterogeneous interacting agents explain macro phenomena through interactions at the micro level. We propose genetic algorithms as a model for individual expectations to explain aggregate market phenomena. The model explains all stylized facts observed in aggregate price fluctuations...

Formulating a model which summarises transportation costs, uncertainty and price, we describe how a switch to ICT procurement can impact more readily procured services rather than materials. Uncertainty represents a catch-all factor describing the dovetailing of operations between two neither...

How can we explain the observed behavior of aggregate inflation in response to e.g. monetary policy changes? Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually...

As consumers’ demand for organic products and especially organic food grows, organic certification for tropical fruit is increasingly promoted in many developing countries. Certified organic pineapple exports only started taking off after 2005 and are rapidly increasing. The organic and...

The European emissions trading scheme (EU-ETS) for CO2 is the largest existing emissions trading scheme in the world. The main reason for the implementation of this scheme is to reach the European Kyoto targets at minimal cost and to establish a price for emissions. The right to emit CO2...

The Ethiopian government initiated the Ethiopian Coffee Trademarking and Licensing Initiative in 2004 for three coffee origins: Sidama, Yirgacheffe and Harar. Following a court case between Starbucks and the Ethiopian government regarding this initiative, Oxfam organized a publicity campaign....

In 2005, the European Emission Trading Scheme (EU-ETS) established a new commodity: the right to emit a ton of CO2 (EUA). Since its launch, the corresponding price has shown rather turbulent dynamics, including nervous reactions to policy announcements and a price collapse after a visible...

Since 2005, the EU ETS has provided a market-based price signal for European carbon emissions, accompanied by increasing economic research related to this policy instrument. In this paper, we carry out a review of the empirical literature examining allowance price formation. A consensus has...

In this paper we empirically investigate potential determinants of allowance (EUA) price dynamics in the European Union Emission Trading Scheme (EU ETS) during Phase II. In contrast to previous papers, we analyze a significantly longer time series, place particular emphasis on the importance of...
