A creepy world
Sornette, Didier; Cauwels, Peter - 2013
Using the mechanics of creep in material sciences as a metaphor, we present a general framework to understand the evolution of financial, economic and social systems and to construct scenarios for the future. In a nutshell, highly non-linear out-of-equilibrium systems subjected to exogenous...

LPPLS bubble indicators over two centuries of the S&P 500 index
Zhang, Qunzhi; Sornette, Didier; Balcilar, Mehmet; … - 2016
The aim of this paper is to present novel tests for the early causal diagnostic of positive and negative bubbles in the … LPPLS (log-periodic power law singularity) approach successfully diagnoses positive and negative bubbles, constructs … efficient End-of-Bubble signals for all of the well-documented bubbles, and obtains for the first time new statistical evidence …

Inferring fundamental value and crash nonlinearity from bubble calibration
Yan, Wanfeng; Woodard, Ryan; Sornette, Didier - 2010
of new models based on the Johansen-Ledoit-Sornette (JLS) model, which is a flexible tool to detect bubbles and predict … dynamics of a crash after a bubble. We test the models using data from three historical bubbles ending in crashes from … Shanghai Composite index 2009 crash. All results suggest that the new models perform very well in describing bubbles …

U.S. metropolitan house price dynamics
Oikarinen, Elias; Bourassa, Steven C.; Hoesli, Martin; … - 2017
Using data for 70 U.S. metropolitan areas, this study explores spatial heterogeneity in house price dynamics. We use recent advances in panel econometrics that allow for spatial heterogeneity, cross-sectional dependence, and non-stationary but cointegrated data. We test for spatial differences...

A model of financial bubbles and drawdowns with non-local behavioral self-referencing
Malevergne, Yannick; Sornette, Didier; Wei, Ran - 2021
We propose a novel class of models in which the crash hazard rate is determined by a function of a non-local estimation of mispricing. Rooted in behavioral finance, the non-local estimation embodies in particular the characteristic of "anchoring" on past price levels and the "probability...

Rational asset pricing bubbles and portfolio constraints
Hugonnier, Julien - 2010
This article shows that the presence of portfolio constraints can give rise to rational asset pricing bubbles in … opportunities. Furthermore, it is shown that when they are present bubbles can lead to both multiplicity and real indeterminacy of … make bubbles a necessary condition for the existence of an equilibrium …
