Boiling the Frog By PAUL KRUGMAN

Is America on its way to becoming a boiled frog?

I’m referring, of course, to the proverbial frog that, placed in a pot of cold water that is gradually heated, never realizes the danger it’s in and is boiled alive. Real frogs will, in fact, jump out of the pot — but never mind. The hypothetical boiled frog is a useful metaphor for a very real problem: the difficulty of responding to disasters that creep up on you a bit at a time.

And creeping disasters are what we mostly face these days.

I started thinking about boiled frogs recently as I watched the depressing state of debate over both economic and environmental policy. These are both areas in which there is a substantial lag before policy actions have their full effect — a year or more in the case of the economy, decades in the case of the planet — yet in which it’s very hard to get people to do what it takes to head off a catastrophe foretold.

And right now, both the economic and the environmental frogs are sitting still while the water gets hotter.

Start with economics: last winter the economy was in acute crisis, with a replay of the Great Depression seeming all too possible. And there was a fairly strong policy response in the form of the Obama stimulus plan, even if that plan wasn’t as strong as some of us thought it should have been.

At this point, however, the acute crisis has given way to a much more insidious threat. Most economic forecasters now expect gross domestic product to start growing soon, if it hasn’t already. But all the signs point to a “jobless recovery”: on average, forecasters surveyed by The Wall Street Journal believe that the unemployment rate will keep rising into next year, and that it will be as high at the end of 2010 as it is now.

Now, it’s bad enough to be jobless for a few weeks; it’s much worse being unemployed for months or years. Yet that’s exactly what will happen to millions of Americans if the average forecast is right — which means that many of the unemployed will lose their savings, their homes and more.

To head off this outcome — and remember, this isn’t what economic Cassandras are saying; it’s the forecasting consensus — we’d need to get another round of fiscal stimulus under way very soon. But neither Congress nor, alas, the Obama administration is showing any inclination to act. Now that the free fall is over, all sense of urgency seems to have vanished.

This will probably change once the reality of the jobless recovery becomes all too apparent. But by then it will be too late to avoid a slow-motion human and social disaster.

Still, the boiled-frog problem on the economy is nothing compared with the problem of getting action on climate change.

Put it this way: if the consensus of the economic experts is grim, the consensus of the climate experts is utterly terrifying. At this point, the central forecast of leading climate models — not the worst-case scenario but the most likely outcome — is utter catastrophe, a rise in temperatures that will totally disrupt life as we know it, if we continue along our present path. How to head off that catastrophe should be the dominant policy issue of our time.

But it isn’t, because climate change is a creeping threat rather than an attention-grabbing crisis. The full dimensions of the catastrophe won’t be apparent for decades, perhaps generations. In fact, it will probably be many years before the upward trend in temperatures is so obvious to casual observers that it silences the skeptics. Unfortunately, if we wait to act until the climate crisis is that obvious, catastrophe will already have become inevitable.

And while a major environmental bill has passed the House, which was an amazing and inspiring political achievement, the bill fell well short of what the planet really needs — and despite this faces steep odds in the Senate.

What makes the apparent paralysis of policy especially alarming is that so little is happening when the political situation seems, on the surface, to be so favorable to action.

After all, supply-siders and climate-change-deniers no longer control the White House and key Congressional committees. Democrats have a popular president to lead them, a large majority in the House of Representatives and 60 votes in the Senate. And this isn’t the old Democratic majority, which was an awkward coalition between Northern liberals and Southern conservatives; this is, by historical standards, a relatively solid progressive bloc.

And let’s be clear: both the president and the party’s Congressional leadership understand the economic and environmental issues perfectly well. So if we can’t get action to head off disaster now, what would it take?

I don’t know the answer. And that’s why I keep thinking about boiling frogs.

Rethinking assessment and accountability: assessment as learning
Around the world, assessment is becoming an extremely “high stakes” activity for students, teachers, and schools. At the same time, there is widespread dissatisfaction with the available assessment procedures. Assessment reform, like other educational changes, is caught in a maelstrom of rapid change and uncertainty (p. 150).
Reporting is about communication, not mere information giving. Judgments do not arrive suddenly, by surprise, when it is too late to do anything about them. No secrets, no surprises: there are key principles of positive assessment practice in Rich’s classroom. (p. 153)
It is important to involve students in the assessment process not just to avoid nasty surprises, but also to develop their own skills in self-assessment: an extremely valuable form of learning in itself. If students are to become critical thinkers and problem solvers who can bring their talents and knowledge to bear on a particular problem, then developing such skills of self-assessment and self-judgment is essential. (p. 154)
Assessment is, by definition, judgmental. It is a deeply personal and emotional experience for the student being assessed; and it can have a far-reaching impact on individual students, on educators, and on the nature of the society in which they live. It is no wonder that decisions and ideas about assessment practices and assessment reform are often not reasoned, logical, or objective. They are too closely tied to people’s deeper beliefs, their fears, and their aspirations. (p. 158).
Darling-Hammond, L. (1994). National standards and assessments: Will they improve
education? American Journal of Education 102, 4: 478-510
Two very different theories of school reform are working in parallel and sometimes at cross-purposes…. One theory focuses on tightening the controls: more courses, more tests, more directive curriculum, more standards enforced by more rewards, and more sanctions. These reforms would improve education by developing more tests and tying funds to schools’ test scores…. A second theory attends more to the qualifications and capacities of teachers and to developing schools through changes in teacher education, licensing, and certification processes,… professional development schools, efforts to decentralize school decision making while infusing knowledge, changing local assessment practices, and developing networks among teachers and schools (p. 22).
It is ironic that the word assessment is derived from the Latin word assidere: to sit with (Wiggins, 1993).
Wiggins, G. (1993). Assessing student performance. San Francisco: Jossey-Bass
When assessment is seen as learning, teachers are the key, with responsibility for the breadth and depth of students’ expression of learning. (p. 167)

America the Tarnished
By PAUL KRUGMAN

Ten years ago the cover of Time magazine featured Robert Rubin, then Treasury secretary, Alan Greenspan, then chairman of the Federal Reserve, and Lawrence Summers, then deputy Treasury secretary. Time dubbed the three “the committee to save the world,” crediting them with leading the global financial system through a crisis that seemed terrifying at the time, although it was a small blip compared with what we’re going through now.

All the men on that cover were Americans, but nobody considered that odd. After all, in 1999 the United States was the unquestioned leader of the global crisis response. That leadership role was only partly based on American wealth; it also, to an important degree, reflected America’s stature as a role model. The United States, everyone thought, was the country that knew how to do finance right.

How times have changed.

Never mind the fact that two members of the committee have since succumbed to the magazine cover curse, the plunge in reputation that so often follows lionization in the media. (Mr. Summers, now the head of the National Economic Council, is still going strong.) Far more important is the extent to which our claims of financial soundness — claims often invoked as we lectured other countries on the need to change their ways — have proved hollow.

Indeed, these days America is looking like the Bernie Madoff of economies: for many years it was held in respect, even awe, but it turns out to have been a fraud all along.

It’s painful now to read a lecture that Mr. Summers gave in early 2000, as the economic crisis of the 1990s was winding down. Discussing the causes of that crisis, Mr. Summers pointed to things that the crisis countries lacked — and that, by implication, the United States had. These things included “well-capitalized and supervised banks” and reliable, transparent corporate accounting. Oh well.

One of the analysts Mr. Summers cited in that lecture, by the way, was the economist Simon Johnson. In an article in the current issue of The Atlantic, Mr. Johnson, who served as the chief economist at the I.M.F. and is now a professor at M.I.T., declares that America’s current difficulties are “shockingly reminiscent” of crises in places like Russia and Argentina — including the key role played by crony capitalists.

In America as in the third world, he writes, “elite business interests — financiers, in the case of the U.S. — played a central role in creating the crisis, making ever-larger gambles, with the implicit backing of the government, until the inevitable collapse. More alarming, they are now using their influence to prevent precisely the sorts of reforms that are needed, and fast, to pull the economy out of its nosedive.”

It’s no wonder, then, that an article in yesterday’s Times about the response President Obama will receive in Europe was titled “English-Speaking Capitalism on Trial.”

Now, in fairness we have to say that the United States was far from being the only nation in which banks ran wild. Many European leaders are still in denial about the continent’s economic and financial troubles, which arguably run as deep as our own — although their nations’ much stronger social safety nets mean that we’re likely to experience far more human suffering. Still, it’s a fact that the crisis has cost America much of its credibility, and with it much of its ability to lead.

And that’s a very bad thing.

Like many other economists, I’ve been revisiting the Great Depression, looking for lessons that might help us avoid a repeat performance. And one thing that stands out from the history of the early 1930s is the extent to which the world’s response to crisis was crippled by the inability of the world’s major economies to cooperate.

The details of our current crisis are very different, but the need for cooperation is no less. President Obama got it exactly right last week when he declared: “All of us are going to have to take steps in order to lift the economy. We don’t want a situation in which some countries are making extraordinary efforts and other countries aren’t.”

Yet that is exactly the situation we’re in. I don’t believe that even America’s economic efforts are adequate, but they’re far more than most other wealthy countries have been willing to undertake. And by rights this week’s G-20 summit ought to be an occasion for Mr. Obama to chide and chivy European leaders, in particular, into pulling their weight.

But these days foreign leaders are in no mood to be lectured by American officials, even when — as in this case — the Americans are right.

The financial crisis has had many costs. And one of those costs is the damage to America’s reputation, an asset we’ve lost just when we, and the world, need it most.

Climate of Change
By PAUL KRUGMAN

Elections have consequences. President Obama’s new budget represents a huge break, not just with the policies of the past eight years, but with policy trends over the past 30 years. If he can get anything like the plan he announced on Thursday through Congress, he will set America on a fundamentally new course.

The budget will, among other things, come as a huge relief to Democrats who were starting to feel a bit of postpartisan depression. The stimulus bill that Congress passed may have been too weak and too focused on tax cuts. The administration’s refusal to get tough on the banks may be deeply disappointing. But fears that Mr. Obama would sacrifice progressive priorities in his budget plans, and satisfy himself with fiddling around the edges of the tax system, have now been banished.

For this budget allocates $634 billion over the next decade for health reform. That’s not enough to pay for universal coverage, but it’s an impressive start. And Mr. Obama plans to pay for health reform, not just with higher taxes on the affluent, but by putting a halt to the creeping privatization of Medicare, eliminating overpayments to insurance companies.

On another front, it’s also heartening to see that the budget projects $645 billion in revenues from the sale of emission allowances. After years of denial and delay by its predecessor, the Obama administration is signaling that it’s ready to take on climate change.

And these new priorities are laid out in a document whose clarity and plausibility seem almost incredible to those of us who grew accustomed to reading Bush-era budgets, which insulted our intelligence on every page. This is budgeting we can believe in.

Many will ask whether Mr. Obama can actually pull off the deficit reduction he promises. Can he actually reduce the red ink from $1.75 trillion this year to less than a third as much in 2013? Yes, he can.

Right now the deficit is huge thanks to temporary factors (at least we hope they’re temporary): a severe economic slump is depressing revenues and large sums have to be allocated both to fiscal stimulus and to financial rescues.

But if and when the crisis passes, the budget picture should improve dramatically. Bear in mind that from 2005 to 2007, that is, in the three years before the crisis, the federal deficit averaged only $243 billion a year. Now, during those years, revenues were inflated, to some degree, by the housing bubble. But it’s also true that we were spending more than $100 billion a year in Iraq.

So if Mr. Obama gets us out of Iraq (without bogging us down in an equally expensive Afghan quagmire) and manages to engineer a solid economic recovery — two big ifs, to be sure — getting the deficit down to around $500 billion by 2013 shouldn’t be at all difficult.

But won’t the deficit be swollen by interest on the debt run-up over the next few years? Not as much as you might think. Interest rates on long-term government debt are less than 4 percent, so even a trillion dollars of additional debt adds less than $40 billion a year to future deficits. And those interest costs are fully reflected in the budget documents.

So we have good priorities and plausible projections. What’s not to like about this budget? Basically, the long run outlook remains worrying.

According to the Obama administration’s budget projections, the ratio of federal debt to G.D.P., a widely used measure of the government’s financial position, will soar over the next few years, then more or less stabilize. But this stability will be achieved at a debt-to-G.D.P. ratio of around 60 percent. That wouldn’t be an extremely high debt level by international standards, but it would be the deepest in debt America has been since the years immediately following World War II. And it would leave us with considerably reduced room for maneuver if another crisis comes along.

Furthermore, the Obama budget only tells us about the next 10 years. That’s an improvement on Bush-era budgets, which looked only 5 years ahead. But America’s really big fiscal problems lurk over that budget horizon: sooner or later we’re going to have to come to grips with the forces driving up long-run spending — above all, the ever-rising cost of health care.

And even if fundamental health care reform brings costs under control, I at least find it hard to see how the federal government can meet its long-term obligations without some tax increases on the middle class. Whatever politicians may say now, there’s probably a value-added tax in our future.

But I don’t blame Mr. Obama for leaving some big questions unanswered in this budget. There’s only so much long-run thinking the political system can handle in the midst of a severe crisis; he has probably taken on all he can, for now. And this budget looks very, very good.

Last Sunday President-elect Barack Obama was asked whether he would seek an investigation of possible crimes by the Bush administration. “I don’t believe that anybody is above the law,” he responded, but “we need to look forward as opposed to looking backwards.”

I’m sorry, but if we don’t have an inquest into what happened during the Bush years — and nearly everyone has taken Mr. Obama’s remarks to mean that we won’t — this means that those who hold power are indeed above the law because they don’t face any consequences if they abuse their power.

Let’s be clear what we’re talking about here. It’s not just torture and illegal wiretapping, whose perpetrators claim, however implausibly, that they were patriots acting to defend the nation’s security. The fact is that the Bush administration’s abuses extended from environmental policy to voting rights. And most of the abuses involved using the power of government to reward political friends and punish political enemies.

At the Justice Department, for example, political appointees illegally reserved nonpolitical positions for “right-thinking Americans” — their term, not mine — and there’s strong evidence that officials used their positions both to undermine the protection of minority voting rights and to persecute Democratic politicians.

The hiring process at Justice echoed the hiring process during the occupation of Iraq — an occupation whose success was supposedly essential to national security — in which applicants were judged by their politics, their personal loyalty to President Bush and, according to some reports, by their views on Roe v. Wade, rather than by their ability to do the job.

Speaking of Iraq, let’s also not forget that country’s failed reconstruction: the Bush administration handed billions of dollars in no-bid contracts to politically connected companies, companies that then failed to deliver. And why should they have bothered to do their jobs? Any government official who tried to enforce accountability on, say, Halliburton quickly found his or her career derailed.

There’s much, much more. By my count, at least six important government agencies experienced major scandals over the past eight years — in most cases, scandals that were never properly investigated. And then there was the biggest scandal of all: Does anyone seriously doubt that the Bush administration deliberately misled the nation into invading Iraq?

Why, then, shouldn’t we have an official inquiry into abuses during the Bush years?

One answer you hear is that pursuing the truth would be divisive, that it would exacerbate partisanship. But if partisanship is so terrible, shouldn’t there be some penalty for the Bush administration’s politicization of every aspect of government?

Alternatively, we’re told that we don’t have to dwell on past abuses, because we won’t repeat them. But no important figure in the Bush administration, or among that administration’s political allies, has expressed remorse for breaking the law. What makes anyone think that they or their political heirs won’t do it all over again, given the chance?

In fact, we’ve already seen this movie. During the Reagan years, the Iran-contra conspirators violated the Constitution in the name of national security. But the first President Bush pardoned the major malefactors, and when the White House finally changed hands the political and media establishment gave Bill Clinton the same advice it’s giving Mr. Obama: let sleeping scandals lie. Sure enough, the second Bush administration picked up right where the Iran-contra conspirators left off — which isn’t too surprising when you bear in mind that Mr. Bush actually hired some of those conspirators.

Now, it’s true that a serious investigation of Bush-era abuses would make Washington an uncomfortable place, both for those who abused power and those who acted as their enablers or apologists. And these people have a lot of friends. But the price of protecting their comfort would be high: If we whitewash the abuses of the past eight years, we’ll guarantee that they will happen again.

Meanwhile, about Mr. Obama: while it’s probably in his short-term political interests to forgive and forget, next week he’s going to swear to “preserve, protect, and defend the Constitution of the United States.” That’s not a conditional oath to be honored only when it’s convenient.

And to protect and defend the Constitution, a president must do more than obey the Constitution himself; he must hold those who violate the Constitution accountable. So Mr. Obama should reconsider his apparent decision to let the previous administration get away with crime. Consequences aside, that’s not a decision he has the right to make.



Reckonings; Power and Profits By PAUL KRUGMAN

Reckonings; Power and Profits

”Let them eat cake!” cried the new president’s friend, a key campaign supporter who was also a prominent advocate of bakery deregulation, not to mention the owner of a chain of cake shops.

O.K., not exactly. Kenneth Lay, chairman of Enron, was a prime mover in George W. Bush’s presidential campaign; he has also been an influential voice in favor of electricity deregulation, and Enron is profiting handsomely from the electricity it sells in California. But what he actually said was that California’s power consumers ”need to see the price signals [that is, pay much more] and start modifying behavior to reduce demand until we get new supplies.” He also rejected the plea of California officials for a federally imposed cap on wholesale electricity prices, arguing that this would merely ‘’start spreading the shortage around.” And his friend the president has echoed his views.

Full disclosure: Before this newspaper’s conflict-of-interest rules required me to resign, I served on an Enron advisory board that turns out to have been a hatchery for future Bush administration officials. (What was I doing there? Beats me.) I can’t say that I got to know Mr. Lay well, but I presume that he is an honorable man. He was, I assume, sincere in those remarks — which one can’t say about everything one has heard from former members of that board — and he also, one must admit, has a point. But in a deeper sense he is missing the point.

It’s true that the California power system lacks adequate conservation incentives. The regulated prices paid by homes and businesses do not rise or fall with the wholesale price. So even in a situation of severe shortage, with wholesale electricity selling for many times its normal price, individuals have no incentive to cut back; that is why there are blackouts.

Why didn’t California deregulate the whole shebang? For a very good reason: The distribution of power, its actual delivery to your house, is still a ”natural monopoly” — you can’t have multiple power lines running down each street. It would have been bad economics and worse politics to give the utilities that distribute electricity free rein to exercise their monopoly power. Someone should have warned that the system needed nonetheless to give consumers an incentive to conserve during power shortages; but the enthusiasts for deregulation led state officials to believe that power would be so abundant that such technical details wouldn’t matter.

Clearly, it’s a priority for California to revise that pricing system. But even so, there is a very good case for a wholesale price cap; far from ‘’spreading the shortage,” such a cap would probably increase short-term supplies, and provide some much-needed financial relief.

The most pressing problem, after all, is not the blackouts but the imminent bankruptcy of the utilities; their financial distress also indirectly contributes to the blackouts, because of the difficulty they have in paying suppliers. And the wild wholesale market also, arguably, leads to another source of reduced supply: power-generating companies have a clear incentive to produce less than they can, because doing so drives up the prices they get on what they do produce. A temporary price cap would both take off some of the financial pressure and reduce the incentives to ”game the system.”

And there’s a deeper principle involved, too.

Nobody to the right of Ralph Nader denies that prices have to be allowed to serve a role as ‘’signals” of shortage or abundance, that the profit motive is what makes our economy run. But even now the public rightfully draws a line, fuzzy but real, between profits and profiteering. Natural gas prices that rise in a cold winter are acceptable; $10 a gallon for bottled water after a hurricane is not.

And one can sympathize with the many people in California who feel that what is happening to them falls on the wrong side of that line — that the Houston-based companies that helped sell naive officials on the glories of a deregulated market are now saying: ”Sorry, it hasn’t worked out the way we promised, but tough luck — you’ll pay the cost for our mistake, and we’ll profit. And don’t even think about alternatives — our friend the president won’t let you try them.” It’s not entirely fair — but it’s not entirely unfair, either.

Houston, you have a problem.
