Understanding the effects of a new regulation is quite a significant quest that arises from the drafters while processing ideas to become effective. In fact, there are several effects that could be considered, including the legal impact, namely the modification of the legal background that takes place whenever we introduce a new norm, the economic effects, in particular the costs that are imposed by the law to organisms including the state, companies and other bodies, the social effects like the change of job statuses of citizens, or citizenship statuses of workers or other subjects. Understanding these aspects preliminarily is a good deem of many drafters. In this seminar we illustrate the research activities of the KREARTI research group in Verona, where we aim at delivering a prototype of a system to assist the drafter de iure condendo into developing a new law, so that she can value the future effects of the issue of that law, before to have it in force. The aforementioned goal can be achieved by means of a simulator, that, while observing an artificial society, digital twin of the actual society on which the law takes place, allows to measure the consequences of the issue of a new law, in order to assist the drafter in the process of designing the norm itself. The system is described and the research plan that shall bring us to the prototype is illustrated and discussed.
