Paul Krugman: The Medicare Miracle

Posted: 01 Sep 2014 12:24 AM PDT

Good news on health care costs:

The Medicare Miracle, By Paul Krugman, Commentary, NY Times: So, what do you think about those Medicare numbers? What, you haven't heard about them? Well, they haven't been front-page news. But something remarkable has been happening on the health-spending front, and it should (but probably won't) transform a lot of our political debate.
The story so far: We've all seen projections of giant federal deficits... Policy wonks have long known ... that ... health care, rather than retirement, was driving those scary projections. Why? Because, historically, health spending has grown much faster than G.D.P., and it was assumed that this trend would continue.
But a funny thing has happened: Health spending has slowed sharply ... This is a really big deal...
But what accounts for this good news? ... Medicare is spending much less than expected, and those Obamacare cost-saving measures are at least part of the story. The conventional wisdom on what is and isn't serious is completely wrong.
While we're on the subject of health costs, there are two other stories you should know about.
One involves the supposed savings from running Medicare through for-profit insurance companies. That's the way the drug benefit works, and conservatives love to point out that this benefit has ended up costing much less than projected, which they claim proves that privatization is the way to go. But the budget office has a new report on this issue, and it finds that privatization had nothing to do with it. Instead, Medicare Part D is costing less than expected partly because enrollment has been low and partly because an absence of new blockbuster drugs has led to an overall slowdown in pharmaceutical spending.
The other involves the "sticker shock" that opponents of health reform have been predicting for years. Bulletin: It's still not happening. ...
What's the moral here? For years, pundits and politicians have insisted that guaranteed health care is an impossible dream, even though every other advanced country has it. Covering the uninsured was supposed to be unaffordable; Medicare as we know it was supposed to be unsustainable. But it turns out that incremental steps to improve incentives and reduce costs can achieve a lot, and covering the uninsured isn't hard at all.
When it comes to ensuring that Americans have access to health care, the message of the data is simple: Yes, we can.

What Savings Glut?

Posted: 31 Aug 2014 08:52 AM PDT

Joe Stiglitz in a review of Martin Wolf's new book "The Shifts and the Shocks":

... If I have a point of difference with Wolf's analysis, it is that he ... is insufficiently critical of the "savings glut" hypothesis advanced by former Federal Reserve chairman Ben Bernanke, among others, which presents what used to be a virtue (savings) as a vice, shifting blame to China and (less vocally) to Germany. Yet the investment needs of today are staggering: for infrastructure in the developing world, let alone in the US; for retrofitting the global economy to cope with global warming; even for small and medium-sized enterprises starved of capital in much of the world. This should make it obvious that the problem is not an excess of savings but a financial system that is more fixated on speculation than on fulfilling its societal role of intermediation ... in which scarce savings are allocated to the investments of highest social returns.

The problem goes beyond a "financial system that is more fixated on speculation":

It is striking how much Wolf, like so many advocates of financial reform, focuses on protecting us against the banks: making sure that they don't engage in excessive risk-taking... Wolf doesn't dwell much on some of the more antisocial aspects evidenced in the aftermath of the crisis: the market manipulation (as in the Libor and forex scandals), the anti-competitive practices, the predatory and discriminatory lending, the lack of transparency, the fraudulent behavior. Presumably, this is because he believes, or hopes, that even too-big-to-fail and too-big-to-jail banks won't be politically powerful enough to continue such behavior unimpaired. But he says too little about what might be done to make banks actually fulfill the societal role that they should be playing. ...

'Where Danger Lurks'

Posted: 31 Aug 2014 08:24 AM PDT

Olivier Blanchard (a much shortened version of his arguments, the entire piece is worth reading):

Where Danger Lurks: Until the 2008 global financial crisis, mainstream U.S. macroeconomics had taken an increasingly benign view of economic fluctuations in output and employment. The crisis has made it clear that this view was wrong and that there is a need for a deep reassessment. ...
That small shocks could sometimes have large effects and, as a result, that things could turn really bad, was not completely ignored by economists. But such an outcome was thought to be a thing of the past that would not happen again, or at least not in advanced economies thanks to their sound economic policies. ... We all knew that there were "dark corners"—situations in which the economy could badly malfunction. But we thought we were far away from those corners, and could for the most part ignore them. ...
The main lesson of the crisis is that we were much closer to those dark corners than we thought—and the corners were even darker than we had thought too. ...
How should we modify our benchmark models—the so-called dynamic stochastic general equilibrium (DSGE) models...? The easy and uncontroversial part of the answer is that the DSGE models should be expanded to better recognize the role of the financial system—and this is happening. But should these models be able to describe how the economy behaves in the dark corners?
Let me offer a pragmatic answer. If macroeconomic policy and financial regulation are set in such a way as to maintain a healthy distance from dark corners, then our models that portray normal times may still be largely appropriate. Another class of economic models, aimed at measuring systemic risk, can be used to give warning signals that we are getting too close to dark corners, and that steps must be taken to reduce risk and increase distance. Trying to create a model that integrates normal times and systemic risks may be beyond the profession's conceptual and technical reach at this stage.
The crisis has been immensely painful. But one of its silver linings has been to jolt macroeconomics and macroeconomic policy. The main policy lesson is a simple one: Stay away from dark corners.

That may be the best we can do for now (have separate models for normal times and "dark corners"), but an integrated model would be preferable. An integrated model would, for example, be better for conducting "policy and financial regulation ... to maintain a healthy distance from dark corners," and our aspirations ought to include models that can explain both normal and abnormal times. That may mean moving beyond the DSGE class of models, or perhaps the technical reach of DSGE models can be extended to incorporate the kinds of problems that can lead to Great Recessions, but we shouldn't be satisfied with models of normal times that cannot explain and anticipate major economic problems.
