Keynesian Baloney (2)

No seguimento de Keynesian Baloney, Government Bloat is Not Growth: Real Gross Domestic Private Product, 2000–2011:

Generations of elementary economics students since World War II have come away from Economics 101 having learned, if anything, that gross domestic product is defined as

GDP = C + I + G + (X - M).

That is, GDP for a given period, usually a year, is the sum of spending for final goods and services by domestic private consumers, domestic private investors, and governments at all levels, plus foreign purchases of U.S. exports minus American purchases of U.S. imports.

This sort of accounting supplies the basic framework for the Keynesian models that swept the economics profession in the 1940s and 1950s, from which a key policy conclusion was derived—that the government can vary its spending to offset shortfalls or excesses of private spending and thereby stabilize the economy’s growth while maintaining “full employment.” From the beginning, the most emphasized part of this conclusion was that increases in government spending can offset declines in private spending and thereby prevent or moderate macroeconomic contractions.
.. private product has lost ground relative to total official GDP. Moreover, many of the measures taken to deal with the contraction—the government’s huge run-up in its spending and debt; the Fed’s great expansion of bank reserves, its allocation of credit directly to failing companies and struggling sectors, and its accommodation of the federal government’s gigantic deficits; and the government’s enactment of extremely unsettling regulatory statutes ..have served to discourage the private investment needed to hasten the recovery and lay the foundation for more rapid economic growth in the long run ..

.. If the government and the Fed persist in the kind of destructive policies they have undertaken since 2007, the potential for another great depression will remain. Even without such a catastrophe, the U.S. economy presents at best the prospect of weak performance for many years to come.
