Crisis and financial regulations

The global crisis brought about resurrecting a debate nearly as old as economics itself: the relationship between state and market. From W. Petty, F. Quesnay and A. Smith JM Keynes, L. von Mises, F. Hayek and M. Friedman, all the great economists of the world expressed their views over time on this important topic. Without going here into details of different argument positions, it appears that there are five major doctrinal guidelines, which correspond to as many as many forms of political action: 1) classical liberalism, 2) the welfare state, 3) keynesianismul, 4) direct interventionism ; 5) neoliberalism.
