Sabiduría de Pigou

Interesante análisis de Mario Rizzo sobre los impuestos y subsidios pigovianos. La frase de Pigou en la que él mismo recomienda prudencia respecto a su análisis es excelente:

"It must be confessed, however, that we seldom know enough to decide what fields and to what extent the State, on account of them, could usefully interfere with individual freedom of choice. Moreover, even though economists were able to provide a perfect blueprint for beneficial State action, politicians are not philosopher kings and a blueprint might quickly yield place on their desks to the propaganda of competing pressure groups. ‘Fancy’ finance, like a fancy franchise, whatever its theoretical attractions, has, at all events in a democracy, dim practical prospects."
