When Policy Meets Statistics: The Reinhart and Rogoff Study on Excessive Debt

Knowing how many of us economists toil away in obscurity on most research, I’m always intrigued by what catches the press’s and public’s attention. Take, for example, the significant attention paid to a 2010 study by Harvard economists Carmen Reinhart and Kenneth Rogoff that concluded that countries with debt levels above 90 percent of GDP began showing slower rates of growth. When Thomas Herndon, Michael Ash and Robert Pollin, scholars at the University of Massachusetts at Amherst, recently had trouble replicating Reinhart and Rogoff’s results, the debate played out in national news outlet.

Unfortunately, this discussion quickly devolved from substance to politics to arguments ad hominem. Without getting into the extent to which I or others can validate Reinhart and Rogoff’s (R&R’s) original findings, I offer six cautions for anyone witnessing this or a similar statistical debate with significant policy implications.

Should Social Security Taxes Affect All Wages? A Modest Rise Is Fine, but It’s Not a Panacea

Arithmetic tells us we must either decrease the growth of Social Security spending or increase taxes as a share of gross domestic product.

But we should do it with an eye on fairness, growth and efficiency. We’re all in this together, so higher-income families must give up something to deal both with Social Security shortfalls and those in the budget more generally. A modest increase in the wage base for Social Security has some justification since that base has eroded in recent years. But if extended too far, it exacerbates the squeeze on other government programs. Continue reading

Creative Ways Around a Blunt Sequester

I would like to offer two simple plans, one for Republicans and one for Democrats, to avoid a blunt, across-the-board sequester with no realistic assessment of priorities. Each plan gives both parties something they want without abandoning their core principles. Each also strengthens the party making the proposal by putting the other one on the spot if it fails to move toward a moderate compromise. Continue reading

Desperately Needed: A Strong Treasury Department

Alexander Hamilton, the first Secretary of the Treasury, set the bar very high. The Senate is about to begin debate over President Obama’s nomination of Jack Lew to be Treasury Secretary. Lately, confirmation hearings have often focused on either the personal foibles of candidates or relatively evanescent policy disputes that are soon forgotten. But at a time when fiscal policy is so critical to the nation’s well-being, the Senate should not forget the critical role Treasury has played in forging that agenda.

The key question for the Senate: will Treasury continue to play that powerful role under Lew’s stewardship? Continue reading

Fiscal Policy After ATRA

The fiscal cliff–averting American Taxpayer Relief Act (ATRA) significantly changed the policy landscape for what looks to be an extended budget debate over the year. For one, most (though not all) policy uncertainty over expiring tax cuts and credits was settled for the foreseeable future. Congress is very unlikely to pick up any new revenue measures this year. But the bill also highlights how far we are from meaningful deficit reduction. Continue reading

What the Public Doesn’t Understand About Social Security and Medicare

An earlier short highlighted my research with Caleb Quakenbush into how much people pay in Social Security and Medicare taxes over a lifetime, and how much they receive in benefits. For instance, we found that a two-earner couple making an average wage who turned 65 in 2010 would have paid $722,000 in Social Security and Medicare taxes over their lifetimes, but would receive $966,000 in benefits.

These types of numbers often generate outraged debate over how much seniors are “owed” based on what they “paid in” to Social Security and Medicare. But there is another, more philosophical, issue that these numbers cannot address. Continue reading

Retired Couples Receiving More Years of Support under Social Security

Increased time spent in retirement is a driving factor behind rising Social Security and Medicare costs. A couple that stopped working at the earliest Social Security retirement age in 1940 would expect to receive 19 years of retirement benefits; a similar couple in 2010 would expect 28 years of benefits. By 2080, couples could be receiving retirement support for 33 years. Continue reading

The Case for Optimism in the New Year: Still Standing on the Shoulders of our Forebears

With all the silliness going on in Washington these days, and with recovery from recession slow here and halting in many other developed nations, we could easily adopt a pessimistic attitude that obscures the prospects lying right at our feet. At the beginning of a new year, I think we instead need to pause and reflect on our graces and blessings, even as we confront the obstacles we have placed in the way of realizing our potential.
