Microfounding GARCH Models and Beyond: A Kyle-inspired Model with Adaptive Agents
Michele Vodret, Iacopo Mastromatteo, Bence Toth +1
We relax the strong rationality assumption for the agents in the paradigmatic Kyle model of price formation, thereby reconciling the framework of asymmetrically informed traders wi…
Bounded Rationality and Animal Spirits: A Fluctuation-Response Approach to Slutsky Matrices
Jerome Garnier-Brun, Jean-Philippe Bouchaud, Michael Benzaquen
The Slutsky equation, central in consumer choice theory, is derived from the usual hypotheses underlying most standard models in Economics, such as full rationality, homogeneity, a…
Multivariate Quadratic Hawkes Processes -- Part I: Theoretical Analysis
Cécilia Aubrun, Michael Benzaquen, Jean-Philippe Bouchaud
Quadratic Hawkes (QHawkes) processes have proved effective at reproducing the statistics of price changes, capturing many of the stylised facts of financial markets. Motivated by t…
Paragliders' Launch Trajectory is Universal
Quentin Da Cruz Lopes, Sophie Ramananarivo, Caroline Cohen +1
We designed and built a reduced-scale model experiment to study the paragliding inflation and launching phase at given traction force. We show that the launch trajectory of a singl…
Valveless pumping at low Reynolds numbers
Amselem Gabriel, Clanet Christophe, Benzaquen Michael
Pumping at low Reynolds number is a ubiquitously encountered feature, both in biological organisms and engineered devices. Generating net flow requires the presence of an asymmetry…
A New Spin on Color Quantization
Samy Lakhal, Alexandre Darmon, Michael Benzaquen
We address the problem of image color quantization using a Maximum Entropy based approach. Focusing on pixel mapping we argue that adding thermal noise to the system yields better…
