Tackling climate change is one of the highest challenges which the world economy is currently facing. The European Green Deal, adopted in 2019, sets the European roadmap towards a net-zero greenhouse gas emissions economy. The food system is heavily responsible for greenhouse gas emissions and...

Mit dem Förderschwerpunkt »Ökonomie des Klimawandels« förderte das Bundesministerium für Bildung und Forschung 27 Forschungsprojekte, die wirtschaftliche Aspekte des Klimawandels untersuchten. Im Rahmen der Begleitaktivitäten zu diesem Förderschwerpunkt koordinierten das Zentrum für...

This paper merges two branches of the literature. On one hand we study a heterogeneous agents framework to model exchange rates and stock prices. On the other hand we model the relationship between these two series through a DSGE model. Investors choose one of two rules to form their...

This paper introduces a bubbly asset to a standard macroeconomic model with heterogeneous agents and borrowing constraints. In this tractable quantitative framework, I show the possibility of a return-preserving bubble that absorbs savings with no good investment opportunities. Analysis of the...

We develop a general equilibrium model of asset prices in which the benefits of technological innovation are distributed asymmetrically. Financial market participants do not capture all the economic rents resulting from innovative activity, even when they own shares in innovating firms. Economic...

We quantify disagreement about the economy with ex-ante measures of divergence of opinion among economic forecasters and investigate if economic disagreement has a significant impact on the cross-sectional pricing of individual stocks. We find a significant disagreement premium of 7.2% per...

We develop an RBC model of the stock market with heterogenous firms. Shares value rests on the rent extracted from proprietary technology. Closed form solutions are provided for the value of each firm and for their aggregate, and for each share's beta, under weak assumptions on the shock...

We develop a tractable RBC model of the stock market with heterogenous firms. Shares value rests on the rent extracted from proprietary technology à la Dixit-Stiglitz. We prove the existence and uniqueness of the fundamental equilibrium. Closed form solutions are provided for the market...

We develop a model that reproduces the return and volatility spread between sin and non-sin stocks, where investors trade off dividends with the ethical assessment of companies. We relax the assumption of boycott behaviour and investigate the role played by the dividend share of sin stocks on...
