This paper presents a simulative model of a financial market, based on a fully operating order book with limit and market orders. The heterogeneity of traders is characterized not only with regards to their trading rules, but also by introducing a behavioral individual risk aversion and a...

In this paper we focus on the beneficial role of random strategies in social sciences by means of simple mathematical and computational models. We briefly review recent results obtained by two of us in previous contributions for the case of the Peter principle and the efficiency of a Parliament....

In this paper, making use of recent statistical physics techniques and models, we address the specific role of randomness in financial markets, both at the micro and the macro level. In particular, we review some recent results obtained about the effectiveness of random strategies of investment,...

Building on similarities between earthquakes and extreme financial events, we use a self-organized criticality-generating model to study herding and avalanche dynamics in financial markets. We consider a community of interacting investors, distributed on a small-world network, who bet on the...

A sustainable growth rate – i.e. a growth rate which allows economy to expand without compromising the equilibrium of the natural system – is one of the most important and stimulating topics in growth literature. In this paper two findings will be presented. First of all, a brief...

This paper aims to survey the literature about the Law of One Price in order to document its failure in terms of actual application. After a brief theoretical overview, which starts from classical economists' thought, the reported literature has been classified on the basis of three main...
