On the interplay between speculative bubbles and productive investment

open access: yesEuropean Economic Review, 2019
The aim of this paper is to study the interplay between long term productive investments and more short term and liquid speculative ones. A three-period lived overlapping generations model allows us to make this distinction.

International Equity Flows and Speculative Bubbles: Some Empirical Evidence for South-East Asia [PDF]

open access: yes, 2010
We analyzed the links between international equity flows and speculative bubbles in the equity markets of six South-East Asian countries over the period 19912006.

A Nonlinear Super-Exponential Rational Model of Speculative Financial Bubbles

open access: yes, 2002
Keeping a basic tenet of economic theory, rational expectations, we model the nonlinear positive feedback between agents in the stock market as an interplay between nonlinearity and multiplicative noise.

A Surface‐engineered Microfluidic Device for Antibody‐Mediated Negative Selection of High‐Quality Sperm for Assisted Reproduction

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a microfluidic device with a functionalized surface utilizing a polyoxazoline coating and covalently immobilized gold nanoparticles and anti‐phosphatidylserine antibody. The device efficiently eliminates pre‐apoptotic and apoptotic spermatozoa and yields sperm with substantially improved quality and low DNA damage, offering a simple ...

Contagious speculative bubbles: a note on the Greek sovereign debt crisis [PDF]

open access: yes, 2011
The Greek sovereign debt crisis of 2009/2010 fostered widespread fears of contagion. We analyzed the danger of contagion by studying to which extent news to speculative bubbles in the Greek equity market spread to the equity markets of Portugal, Ireland,

Fearless versus Fearful Speculative Financial Bubbles

open access: yes, 2003
Using a recently introduced rational expectation model of bubbles, based on the interplay between stochasticity and positive feedbacks of prices on returns and volatility, we develop a new methodology to test how this model classifies 9 time series that ...

From Wafers to Electrodes: Transferring Automatic Optical Inspection (AOI) for Multiscale Characterization of Smart Battery Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
Automat optical inspection (AOI) techniques in semiconductor fabrication can be leveraged in battery manufacturing, enabling scalable detection and analysis of electrode‐ and cell‐level imperfections through AI‐driven analytics and a digital‐twin framework.

High‐Resolution and Real‐Time In Situ Generation of Cellular Spheroids by Laser‐Assisted Bioprinting for Guided Microvascularization

open access: yesAdvanced Functional Materials, EarlyView.
Micro‐injection laser‐assisted bioprinting enables ultrafast and precise patterning of small endothelial cell spheroids by injecting a highly concentrated single‐cell suspension into GelMA/ColMA hydrogels. In co‐culture with fibroblasts, controlled pre‐vasculogenic network formation is obtained at microscale resolution.

Market Depth, Leverage, and Speculative Bubbles

open access: yesJournal of the European Economic Association, 2019
We develop a model of rational bubbles based on leverage and the assumption of an imprecisely known maximum market size. In a bubble, traders push the asset price above its fundamental value in a dynamic way, driven by rational expectations about ...

Speculative bubbles and the cross-sectional variation in stock returns [PDF]

open access: yes, 2013
Evidence suggests that rational, periodically collapsing speculative bubbles may be pervasive in stock markets globally, but there is no research that considers them at the individual stock level.
