Due to the strong complexity of financial markets, economics does not have a unified theory of price formation in financial markets. The most common assumption is the Efficient-Market Hypothesis, which has been attacked by a number of researchers, using different tools. There were varying...

Market data for financial studies typically derives from either historical transactions or contemporaneous surveys of sentiment and perceptions. The research communities analyzing data from these opposing categories of source data see themselves as distinct, with advantages not shared by the...

This text was written as part of the project Modelling of Complex Systems for Public Policy. It reviews the classical authors who jointly contributed to establish the elements of what could constitute a "science of complexity". Based on the original writings of these authors, the text discusses...

Psychological research on human creativity focuses primarily on individual creative performance. Assessing creative performance is, however, also a matter of expert evaluation.

The distribution of prot rates in the U.S. economy for 21,714 rms from 1962 - 2012 appears to be highly organized in a Laplace-like distribution. Pos- itive prot rate deviations from the mode appear to be remarkably stationary over time displaying little parametric changes while negative prot...

We analyze nonlinear pricing with finite information. A seller offers a menu to a continuum of buyers with a continuum of possible valuations. The menu is limited to offering a finite number of choices representing a finite communication capacity between buyer and seller. We identify necessary...

Microsimulation models allow targeted simulations to analyze the impacts of alternative policies, measures, scenarios based on microunits like persons, families, households, firms etc. Meanwhile it is out of question that microsimulation models are a helpful, successful and an imperative...
