American Political Leaders Continue to Turn Down a "Free Lunch"

It isn't often that you see an economist identify a "free lunch" and tell you it isn't a scam, that it literally is like a $100 bill lying on the sidewalk waiting to be picked up. Sure there are right wing economists who would walk right by that $100 bill because they believe in "efficient markets" which assures them the bill can't be real because if it were then somebody would have already bent down and pocketed the free money.

Here is the opening of an excellent article by Brad DeLong pointing out a "free lunch" that Obama, the Republicans, and the Democrats are ignoring. They believe the following is like the $100 on the sidewalk. It can't be real otherwise somebody else (the "job creators" in Republican lingo) would have already bent down and grabbed it. But the "free lunch" is real. Here is DeLong spelling it out:

Former US Treasury Secretary Lawrence Summers had a good line at the International Monetary Fund meetings this year: governments, he said, are trying to treat a broken ankle when the patient is facing organ failure. Summers was criticizing Europe’s focus on the second-order issue of Greece while far graver imbalances – between the EU’s north and south, and between reckless banks’ creditors and governments that failed to regulate properly – worsen with each passing day.

But, on the other side of the Atlantic, Americans have no reason to feel smug. Summers could have used the same metaphor to criticize the United States, where the continued focus on the long-run funding dilemmas of social insurance is sucking all of the oxygen out of efforts to deal with America’s macroeconomic and unemployment crisis.

The US government can currently borrow for 30 years at a real (inflation-adjusted) interest rate of 1% per year. Suppose that the US government were to borrow an extra $500 billion over the next two years and spend it on infrastructure – even unproductively, on projects for which the social rate of return is a measly 25% per year. Suppose that – as seems to be the case – the simple Keynesian government-expenditure multiplier on this spending is only two.

In that case, the $500 billion of extra federal infrastructure spending over the next two years would produce $1 trillion of extra output of goods and services, generate approximately seven million person-years of extra employment, and push down the unemployment rate by two percentage points in each of those years. And, with tighter labor-force attachment on the part of those who have jobs, the unemployment rate thereafter would likely be about 0.1 percentage points lower in the indefinite future.

The impressive gains don’t stop there. Better infrastructure would mean an extra $20 billion a year of income and social welfare. A lower unemployment rate into the future would mean another $20 billion a year in higher production. And half of the extra $1 trillion of goods and services would show up as consumption goods and services for American households.

In sum, on the benefits side of the equation: more jobs now, $500 billion of additional consumption of goods and services over the next two years, and then a $40 billion a year flow of higher incomes and production each year thereafter. So, what are the likely costs of an extra $500 billion in infrastructure spending over the next two years?

For starters, the $500 billion of extra government spending would likely be offset by $300 billion of increased tax collections from higher economic activity. So the net result would be a $200 billion increase in the national debt. American taxpayers would then have to pay $2 billion a year in real interest on that extra national debt over the next 30 years, and then pay off or roll over the entire $200 billion.

The $40 billion a year of higher economic activity would, however, generate roughly $10 billion a year in additional tax revenue. Using some of it to pay the real interest on the debt and saving the rest would mean that when the bill comes due, the tax-financed reserves generated by the healthier economy would be more than enough to pay off the additional national debt.

In other words, taxpayers win, because the benefits from the healthier economy would more than compensate for the costs of servicing the higher national debt, enabling the government to provide more services without raising tax rates. Households win, too, because they get to buy more and nicer things with their incomes. Companies win, because goods and workers get to use the improved infrastructure. The unemployed win, because some of them get jobs. And even bond investors win, because they get their money back, with the interest for which they contracted.

So what is not to like? Nothing.

The political "leadership" in America is a joke. These are political hacks more interested in grandstanding and playing ideological gamesmanship than in saving the ship of state from the shoal of depression and years of economic hardship. It is practically criminal that this is happening!
