Who we are



Interactive simulation models are a gym tool for improving our imagination about how the economy works. They are often ambivalent, being both business games and economic formal models.

We freely distribute here many of them. You will typically be able to run the code, see and even change it. Things have been established so that even if you have zero knowledge of programming language, you can still make use of the software. Needless to say, you have to allow code to be performed, which may require that you specifically allow for execution. For instance, in latest Windows version for Excel, you need to explicitly ask to unblock the code. For editing the code, you will need to go to Options and make the Developer Tab visible. Further instructions may be contained in the zipped compressed files with which we are distributing the software.




Essay and Software : You are a monopolist
The traditional monopolist's choice about price and quantity is now given a new dynamic setting where you can interact. Demand is unknown and the produced good is durable across periods of time. Thus, sales needn't be equal to production as inventories can pile up and go down. A lot of strategic consequences arise, as you can discover playing with the business game.
This human participated simulation is part of the suit of models, downloadable from this page, that students can play to become critical and active, as envisaged in the evolutionary theory methodology.

Software: Social security

A very simple software where you can verify the economic sustainability of a pension scheme in a population, depending on retirement age, wages, payroll taxes, age of labour market entry, births and deaths.

Highly customizeable in parametres.


Software: Insurance market competition

A simple yet powerful simulation of insurance market and the decisions take by people-at-risk (applicants) and underwriters (insurers). It lets you explore e.g. why so many people can remain uninsured and which are the connections between profitability and coverage.


Software: Race to market

Useful for managers, researchers and students, this business game is a powerful tool for understanding product life cycles, consumers' attitudes, innovation management strategies, competitive intelligent tactics, by personally playing or by observing how artificial agents perform.

Software: Market dynamics with firm-specific fixed and variable costs

In this easy evolutionary model you'll find a market with a large number of firms, each characterised by a different cost structure, and you'll be able to study the evolution of profits over time, according to changes in demand and endogenous technology progress.

A key statement will relate the way demand interacts with the kind of technological innovation approved by top management.



Software: You are an exporter
This business game will improve your skills in exporting, choosing target countries, fixing prices and quantities, while surfing between business cycles and changes in the cost structure. You'll better understand how the exchange rate impacts on exports and imports.

Suitable for beginners and researchers.
