O consenso sobre os estímulos fiscais

John Cochrane, a professor at the University of Chicago Booth School of Business, says that among academics over the last 30 years, the idea of fiscal stimulus has been discredited and in graduate courses, it is "taught only for its fallacies."

New York University economist Thomas Sargent agrees: "The calculations that I have seen supporting the stimulus package are back-of-the-envelope ones that ignore what we have learned in the last 60 years of macroeconomic research."

Nobel Laureate Gary Becker says any benefits will be modest at best.

For the government to finance infrastructure spending or tax cuts, it has to borrow money. The money is thus unavailable for private investment or consumption. Right now, companies and individuals are having trouble getting credit, which is a big reason for the downturn. But if the government borrows more, they will have an even harder time finding lenders. So the effort could be self-defeating.

Se quiserem apresentações, Thomas Sargent escreveu um livro de macroeconomia usado em quase todos os programas de doutoramento ou mestrado em economia em todo o mundo.
