The Inequality Process (IP) is a stochastic particle system in which particles are randomly paired for wealth exchange. A coin toss determines which particle loses wealth to the other in a randomly paired encounter. The loser gives up a fixed share of its wealth, a positive quantity. That share...

Most social scientists would reject the possibility of socio-economic analogues of the gas laws (Boyle’s and Charles’) on verisimilitude grounds. The gas laws relate the variables temperature, pressure, and volume. The possibility of socio-economic analogues of the gas laws and their...

Four economists, Mauro Gallegati, Steven Keen, Thomas Lux, and Paul Ormerod, published a paper after the 2005 Econophysics Colloquium criticizing conservative particle systems as models of income and wealth distribution. Their critique made science news: coverage in a feature article in Nature....

The Inequality Process (IP) is a particle system model similar to that of the Kinetic Theory of Gases. The IP is a parsimonious model of competition among people for wealth. The IP explains a wide scope of stable patterns in the distribution of personal income and wealth. Econophysicists have...

Economic behavior strives for efficiency. Therefore, also evolving network structures should be a result of such a goal-oriented behavior. Traditionally, networks were assumed to be only temporary phenomena, since the prevailing organizational forms that comply with the efficiency postulate are...

A concept and mathematical model of modern economics are formulated in which a company profit is defined when taking into account possible interests of individual decision makers rather than based exclusively on benefits of either the company (ground of microeconomics) or the whole society...

Researchers describing the discovery of something they are not equipped to fully understand run the risk that their reach will exceed their grasp. And so, as mere enthusiastic newcomers to the study of author Rex Stout, we will limit ourselves to: (1) reporting that we have run across an early...

For more than a century, careful readers of the Green Bag have known that “[t]here is nothing sacred in a theory of law...which has outlived its usefulness or which was radically wrong from the beginning...The question is What is the law and what is the true public policy?” Professor Orin...

Endogenous response time data is increasingly becoming available to applied researchers of economic choices. The drift-diffusion model (DDM) was originally developed to jointly explain subjects' choices and response times in laboratory experiments. Here, we adapt the DDM to a field setting to...
