Bitcoin bubble trouble
Kreuser, Jérôme; Sornette, Didier - 2018 - Revised 18-Jun-18
We present a dynamic Rational Expectations (RE) bubble model of prices with the intention to evaluate it on optimal investment strategies applied to Bitcoin. Our bubble model is defined as a geometric Brownian motion combined with separate crash (and rally) discrete jump distributions associated...

Carry Trades and Financial Crisis : An Analytical Perspective
Wanaguru, Sumila Tharanga - 2011
This paper develops an analytical framework to explain how a liquidity shock or a shock to the aggregate haircut on collateralized assets amplifies financial crisis in a carry trade recipient country. The model allows roles for shocks to the size of a haircut, strategic behaviour across currency...

Rock around the clock: an agent-based model of low- and high-frequency trading
Leal, Sandrine Jacob; Napoletano, Mauro; Roventini, Andrea - 2014
We build an agent-based model to study how the interplay between low- and high- frequency trading affects asset price dynamics. Our main goal is to investigate whether high-frequency trading exacerbates market volatility and generates flash crashes. In the model, low-frequency agents adopt...

Market stability vs. market resilience : regulatory policies experiments in an agent based model with low- and high-frequency trading
Jacob Leal, Sandrine; Napoletano, Mauro - 2016
We investigate the effects of different regulatory policies directed towards high-frequency trading (HFT) through an agent-based model of a limit order book able to generate flash crashes as the result of the interactions between low- and high-frequency (HF) traders. We analyze the impact of the...

On the existence and prevention of speculative bubbles
Enders, Zeno; Hakenes, Hendrik - 2014
We develop a parsimonious model of bubbles based on the assumption of imprecisely known market depth. In a speculative bubble, traders drive the price above its fundamental value in a dynamic way, driven by rational expectations about future price developments. At a previously unknown date, the...

'Speculative Influence Network' During Financial Bubbles : Application to Chinese Stock Markets
Lin, Li - 2015
We introduce the Speculative Influence Network (SIN) to decipher the causal relationships between sectors (and/or firms) during financial bubbles. The SIN is constructed in two steps. First, we develop a Hidden Markov Model (HMM) of regime-switching between a normal market phase represented by a...

Multi-asset financial bubbles in an agent-based model with noise traders' herding described by an n-vector Ising model
Cividino, Davide; Westphal, Rebecca; Sornette, Didier - 2021
We present an agent-based model (ABM) of a financial market with n 1 risky assets, whose price dynamics result from the interaction between rational fundamentalists and trend following imitative noise traders. The interactions and opinion formation of the noise traders are described by an...

The Macroeconomics of Financial Speculation
Simsek, Alp - 2021
I review the literature on financial speculation driven by belief disagreements from a macroeconomics perspective. To …-selling constraints, speculation can generate overvaluation and speculative bubbles. Leverage can substantially inflate speculative …, speculation induces procyclical asset valuation. When speculation affects the price of aggregate assets, it also influences …

Speculative bubbles and contagion : analysis of volatility's clusters during the DotCom bubble based on the dynamic conditional correlation model
Herwarth Kohn, Maximilian-Benedikt; Pereira, Pedro L. Valls - In: Cogent economics & finance 5 (2017) 1, pp. 1-28
Reviewing the definition and measurement of speculative bubbles in context of contagion, this paper analyses the DotCom bubble in American and European equity markets using the dynamic conditional correlation (DCC) model proposed as on one hand as an econometrics explanation and on the other...
