In a number of quantitative applications, a set of non-negative variables summing to a constant value is involved. A software able to generate evenly spaced points on the regular simplex (that is N-tuples summing to one) has been realized and it is freely available to anybody who might be interested

In this paper, we model an agent-based economy in which heterogeneous agents (firms and a bank) interact in the financial markets. The heterogeneity is due to the balance sheet conditions and to size. In our simulations, at the aggregate level, output displays changes in trend and volatility...

In this paper we provide a prototype Multi-Agent macroeconomic system where artificial agents' behavioral rules are calibrated using human behaviors. The artificial representation of humans, i.e. "molded'' avatars, derives from a two steps process. The first step consists in performing...
