Multivariate bubbles and antibubbles

Fluid instabilities in the birth and death of antibubbles

Antibubbles have been produced and studied with the help of a high-speed camera. An antibubble is defined as a fluid object constituted by a thin air shell surrounding a liquid and surrounded by the same liquid. Images reveal some key physical processes and fluid instabilities which take place when an antibubble forms and dies. The collapsing speed of the air film has been measured. Culik’s the...

The financial crisis of 2008, which started with an initially well-defined epicenter focused on mortgage backed securities (MBS), has been cascading into a global economic recession, whose increasing severity and uncertain duration has led and is continuing to lead to massive losses and damage for billions of people. Heavy central bank interventions and government spending programs have been la...

Plugging in and into code bubbles: the code bubbles architecture

Code Bubbles is an attempt to redefine the user interface for an integrated programming environment. As it represents a whole new user interface, implementing it as a plug-in is inherently difficult. We get around this difficulty by combining two different plug-in architectures, a standard one based on registrations and callbacks, and a message-based one that puts the plug-in at arm’s length an...

Bubbles and Overshooting Crash

This paper reviews a model of bubbles under the assumption of heterogeneous rational traders. In the presence of dispersion of opinions, or sequential awareness, financial bubbles are justified by the interactions between rational arbitrageurs and behavioural traders. Timing is a very important component in the trader's strategy. This model is then extended to explain both bubbles and overshoot...
