Complex, 2021 The sharp changes in oil prices since 2004 featured a nonlinear data-generating mechanism which displayed bubble-like behavior. A popular view is that such a salient pattern cannot be explained by shifts in economic fundamentals, but was driven by ...

Speculative bubbles in present-value models: A Bayesian Markov-switching state space approach
Journal of Economic Dynamics and Control, 2021 We estimate the dynamics of a speculative bubble subject to a surviving and a collapsing regime together with the dynamics of dividends and returns in a tractable state space specification of the present-value model. To estimate this new high-dimensional

Learning in speculative bubbles: Theory and experiment
, 2021 Does learning reduce or fuel speculative bubbles? We study this issue in the context of the Bubble Game proposed by Moinas and Pouget (2013). Our theoretical analysis based on adaptive learning shows that i) in the long run, learning induces convergence ...

Investigation of Speculative Bubbles in Financial Markets: The Example of Foreign Exchange Market
, 2021 Financial bubbles are described as the deviation of the market values of financial assets from their core values. They are one of the main indicators for the financial crises by negatively affecting the markets due to the constant overvaluation of the ...

Are speculative bubbles welfare improving? A note on Wang and Wen (2012)
, 2020 Wang and Wen (2012) show in a DSGE model that the existence of speculative bubbles are welfare improving. In their steady state analysis of the benchmark model the authors claim the existence of a unique steady state in the bubble equilibrium with a ...

Crypto Currency and its Susceptibility to Speculative Bubbles, Manipulation, Scams and Fraud
Journal of Advanced Studies in Finance, 2019 It is argued here that because a cryptocurrency has no intrinsic value, problems relating to day-to-day valuation and pricing arise. It is shown how these lead to the reversal of the conventional relationship between supply and demand and the ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
