In several countries, healthcare services are provided by public and/or private subjects, and they are reimbursed by the Government, on the basis of regulated prices. Thus, providers take prices as given and compete on quality to attract patients. In some countries, regulated prices differ...

This article proposes a differential-game model, in order to analyze markets in which regional regulation is operative and competition is based on quality. The case we have in mind is healthcare public service, where consumers (patients) choose the provider mainly basing on the providers'...

This paper proposes a generalization of Shleifer's (1985) model of yardstick competition, to a dynamic framework. Specifically, we consider a differential game and we show that the yardstick mechanism is effective to replicate the first-best solution if players adopt open-loop behaviour rules...

In this paper we try to build a statistical ensemble to describe a cryptocurrency-based system, emphasizing an "affinity" between the system of agents trading in these currencies and statistical mechanics. We focus our study on the concept of entropy in the sense of Boltzmann and we try to...

In this paper, we consider 2 types of instruments traded on the markets, stocks and cryptocurrencies. In particular, stocks are traded in a market subject to opening hours, while cryptocurrencies are traded in a 24-hour market. What we want to demonstrate through the use of a particular type of...

In this paper we want to demonstrate how it is possible to improve the forecast by using Boltzmann entropy like the classic financial indicators, throught neural networks. In particular, we show how it is possible to increase the scope of entropy by moving from cryptocurrencies to equities and...

In this paper we want to describe a model of the dynamics of the Bitcoin cryptocurrency system. We can define a duality in these dynamics: Bitcoin mostly behaves as a deterministic system and in some time intervals, much shorter, it enters a stochastic regime. In particular, using Poincaré’s...
