The Keynesian Fallacy and Regime Uncertainty

In “A Keynesian Fantasy Land,” I gave six reasons for the failure of “stimulus” spending to stimulate the economy, despite the insistence of leftists and left-wing economists that economic salvation is to be found in bigger government. The reasons, which I elaborate in the earlier post, are these:

1. “leakage” to imports

2. disincentivizing effects of government borrowing and spending (regime uncertainty)

3. timing and targeting problems (spending that is too late and misdirected)

4. reversed causality (lower aggregate demand as symptom, not cause)

5. the negative consequences of bail-outs

6. the unaccounted for complexity of human behavior

An article by Casey B. Mulligan, “Simple Analytics and Empirics of the Government Spending Multiplier and Other ‘Keynesian’ Paradoxes,” underscores the futility of “stimulus” spending. These are among Mulligan’s conclusions:

From a partial equilibrium perspective, it would be surprising if government purchases did not crowd out at least some private consumption, and that a reduction in factor supply did not result in less output. Yet some “New Keynesian” models, not to mention much public policy commentary, claim that today’s economy has turned this partial equilibrium reasoning on its head, even while it might have been historically valid. Among other things, individual firms and the aggregate private sector are alleged to leave their production invariant to changes in factor supply conditions during this recession. This paper shows how the government spending multiplier and the “paradox of toil” are related in theory, and examines evidence from this recession on the output effects of factor supply…

This paper does not contain a numerical estimate of the government purchases multiplier. However, its examination of data exclusively from the 2008-9 recession suggests that sectoral and aggregate employment and output vary with supply conditions in much the same way they did before the recession. The results contradict Keynesian claims that the government purchases multiplier would be significantly greater during the recession than it was before 2008, suggesting instead that historical estimates of the effects of fiscal policies are informative about fiscal policy effects in more recent years. Moreover, the supply incentives created by government spending cannot be ignored merely because 2008 and 2009 were recession years; rather incentives mattered as much as ever. Government purchases likely moved factors away from activities that would have supported private purchases. Unemployment insurance, food stamps, and other expanding means-tested government programs likely reduced employment and output during this recession, in much the same way they did in years past.

Compounding the futility of “stimulus” spending is the general climate of economic fear that Obama’s policies have engendered; for example:

Why aren’t we seeing a jobs recovery? Maybe it’s ObamaCare’s fault (at Questions and Observations)

As John Steele Gordon points out,

[t]he greatest periods of American economic growth came when taxes were very low—such as in the 19th century—or being lowered and simplified, as in the 1920s, 60s, and 80s. Inescapably, to tax wealth creation is to discourage it. But there is a large and politically potent segment of the population that, because its interests are now aligned with those of the government, seek to promote dependency through entitlements. This segment favors ever higher taxes (although they disguise the fact by demanding that only “the rich” pay their “fair share.”) But, as with regulation, high taxes inevitably produce low growth—and low growth threatens entitlements in the long term. If the United States remains in the doldrums for several more years without hope of a real turnaround, Medicare as it is currently constituted will go bankrupt in 2019. Raising taxes to prevent that will only slow overall growth, and that will actually defeat the purpose of saving Medicare.

So there is really no alternative to pursuing policies that encourage economic growth through private action by liberating the forces of the free market. A presidential candidate who finds a way to ground his economic policies in this core truth—and harnesses the idea to a larger and more optimistic understanding of the United States, both past and future, and resists the take-your-medicine tone that dominates the conservative policy discussion of the present moment—will be able to draw a sharp and effective contrast with the failures of the Obama years. (“Growth: The Only Way out of This Mess,” Commentary, July 2011)

But there is no point in cutting taxes unless government spending is cut — and cut drastically — for government spending, along with regulation, is the real drag on the economy. Only in the left’s magical thinking is government spending a good thing. In reality, it is a destructive force — even during recessions and depressions.
