El estimulo no va a ser gratis

Gary Becker and Kevin Murphy hablan sobre el plan de estimulo de Obama en el WSJ. Algunos puntos destacados,

• So our conclusion is that the net stimulus to short-term GDP will not be zero, and will be positive, but the stimulus is likely to be modest in magnitude. Some economists have assumed that every $1 billion spent by the government through the stimulus package would raise short-term GDP by $1.5 billion. Or, in economics jargon, that the multiplier is 1.5.
  That seems too optimistic given the nature of the spending programs being proposed. We believe a multiplier well below one seems much more likely.
• "The increased government spending in the stimulus package is supposed to be only temporary, until the economy returns to a full employment level, but probably won't be."
  The evidence of past expansions of government programs is just the opposite. Once created they tend to survive and grow over time, even when the increases initially were said to be temporary. The underlying reason for this is that interest groups develop around new and expanded programs, and they lobby to keep and expand those programs.
• Whatever the merits of other government spending, the spending in this package is likely to have less value. A very large amount of money will be spent quickly over a two-year period: $500 billion amounts to about one-quarter of the total federal government annual spending of $2 trillion. It is extremely difficult for any group, private as well as public, to spend such a large sum wisely in a short period of time.
• The increased federal debt caused by this stimulus package has to be paid for eventually by higher taxes on households and businesses. Higher income and business taxes generally discourage effort and investments, and result in a larger social burden than the actual level of the tax revenue needed to finance the greater debt. The burden from higher taxes down the road has to be deducted both from any short-term stimulus provided by the spending program, and from its long-run effects on the economy.
