In this paper, we consider daily financial data of a collection of different stock market indices, exchange rates, and interest rates, and we analyze their multi-scaling properties by estimating a simple specification of the Markov- switching multifractal model (MSM). In order to see how well...

We develop a model with two types of electricity producers, fossil fuel utilities generating emissions, and suppliers of electricity from renewable resources such as wind energy. We account for the vertical structure of the wind-energy sector by considering wind-turbine producers engaged in...

This paper develops a methodology for estimating the parameters of dynamic opinion or expectation formation processes with social interactions. We study a simple stochastic framework of a collective process of opinion formation by a group of agents who face a binary decision problem. The...

Die Riester-Förderung soll dazu beitragen, dass häufiger und mehr für die Altersvorsorge gespart wird. Der Einfluss der Riester-Förderung auf die Sparneigung von Haushalten mit niedrigem Einkommen ist dabei ein zentrales Kriterium zur ökonomischen Evaluation dieser Politik. Unsere...

This chapter reviews recent research adopting methods from statistical physics in theoretical or empirical work in economics and nance. The bulk of what has recently become known as 'econophysics' in broader circles draws its motivation from observed scaling laws in nancial markets and the...

Based on the observation that industries are often geographically concentrated, this paper proposes a new political economy model of trade protection. We associate the sectors of a specific factors model with electoral districts populated by continua of heterogeneous voters who differ in their...

On the basis of abundant facility and firm-level data for German manufacturing, originating from a recent OECD-survey, this paper empirically investigates the relevance of a variety of incentives for environmentally innovative behavior of facilities, the respective influence of pressure groups,...

This note is concerned with two recent agent-based models of speculative dynamics from the literature, one by Gaunersdorfer and Hommes and the other by He and Li. At short as well as long lags, both of them display an autocorrelation structure in absolute and squared returns that comes...

In diesem Papier wollen wir zum einen kurz die Stärken und Schwächen der EU-Direktive aufzeigen. Zum anderen wollen wir einige offene Fragen diskutieren, die bei der Umsetzung des Emissionshandels auf nationaler Ebene – insbesondere bei der Aufstellung des nationalen Allokationsplans –...

Using an experiment with material incentives, this paper investigates the violation of composite dominance relationships, viz. absolute Pareto dominance, Pareto rank dominance, transfer dominance, Lorenz dominance, and generalized Lorenz dominance. Moreover, we test tail independence. The...
