SSRN Electronic Journal, 1998 Les auteurs de l'étude ont recours à une nouvelle approche empirique, fondée sur l'emploi de méthodes de régression avec changement de régime, en vue de différencier deux modèles d'évaluation des actifs, soit le modèle des bulles et le modèle des engouements.

Bubble, bubble, boil and trouble
Computers in Physics, 1993Multiphase fluid mixtures present not only fascinating examples of nonequilibrium pattern formation, but also illustrate rather general questions concerning new emergent levels of organization. To illustrate these issues, we use lattice-gas cellular automata to study a buoyant mixture of hot and cold bubbles.

SSRN Electronic Journal, 2014 AbstractWhile Eugene Fama has repeatedly expressed his discontent with the notion of an “irrational bubble,” he has never publicly expressed his opinion on “rational bubbles.” On empirical grounds Fama rejects bubbles by referring to the lack of reliable evidence that price declines are predictable.

Japan's Bubble, the USA's Bubble and China's Bubble [PDF]
China & World Economy, 2011 AbstractThis paper compares the three recent episodes of boom and bust cycles in asset prices: Japan in the late 1980s to the 1990s; the USA since the mid‐1990s; and China during the past decade. Although we have not yet seen a collapse of Chinese property prices, their increases so far are comparable to those in the other two episodes and a careful ...

Bubble-bubble interaction in disperse bubble clouds
The Journal of the Acoustical Society of America, 2008Disperse bubble fields driven by pressure waves feature effects of time delays associated with the finite speed of travel of the driving acoustic wave, and the finite travel time of pressure waves between bubbles. The relative spatial arrangement of bubble nuclei in a disperse field, and the direction of the incoming pressure wave, both influence the ...

Microgravity - Science and Technology, 2005
A short overview of boiling research in microgravity performed during the past two decades is subject of this presentation. The research was concentrated on pool boiling without applying any external forces. The objective of this research was to answer the questions: Is boiling an appropriate mechanism of heat transfer in space applications, and how do

Bubbles are familiar from daily life and occupy an important role in physics, chemistry, medicine, and technology. Nevertheless, their behavior is often surprising and unexpected—and, in many cases, still not understood.

Bubble, Bubble, Toil and Trouble
Journal of Chemical Education, 2001Soap bubbles burst when their walls thin because of evaporation or the effects of gravity. Glycerin is thought to increase the lifetime of bubbles because it is hygroscopic and very viscous. Since it is hygroscopic, it helps to prevent evaporation of the water. Its high viscosity increases the time that it takes for downward flow of the material in the

Credit bubbles and land bubbles [PDF]
, 2010 In modern macroeconomic models it is difficult to obtain explosive price bubbles on assets with positive net supply. This paper shows that it is possible to obtain explosive bubbles in certain situations when assets such as land are used as collateral and lenders are willing to lend freely against it.

A bubble may be defined loosely as a sharp rise in price of an asset or a range of assets in a continuous process, with the initial rise generating expectations of further rises and attracting new buyers — generally speculators interested in profits from trading in the asset rather than its use or earning capacity.
