El impôt unique fisiocrático. Su recepción en España.

Despite its limited space-time range (France 1756-1777), the Physiocratic School has left a decisive mark on the history of economic thought. By investigating the cause and nature of national wealth and the methods to increase it, François Quesnay and the other members of the Physiocracy have identified the agricultural sector as the only source of produit net. Among the changes proposed by the Physiocrats to reform the productive structure of a backward society, the most radical is perhaps that of the impôt unique. This paper aims to explain why, despite its undeniable charm, this proposal was destined to fail, both in France and abroad, with particular reference to the case of Spain.
