Abstract
In most parts of the developed countries the economy is regulated through liberal systems. A liberal system means that there exists open markets and competition over these markets. States and governments are not the leaders of these markets. They are only the institutions which have created rules to make the system efficient. Institutions are in charge of the regulation of the market, that is to say that governments are just the referees of the market. They have to control the good application of the rules and may be the drivers of growth when the economy is declining. For example, in France, the government was active during the 90's, even more so when Edouard Balladur was Prime Minister. Effectively, during the year 1993, government was present in French economy to increase French development and French growth. Balladur tried to boost the automobile industry which had suffered a severe economic crisis. His government offered to French inhabitants various incentives to renew their cars.
