Magic

by the Sandwichman

Helicopter Ben finally hauls out the helicopter: "So there are limits to the Fed's magical powers, and they already began showing up in currency markets this afternoon, with the dollar falling sharply against the euro and other foreign currencies. The adventure continues."

The effects of magic must be to weaken intellectual inquisitiveness, to encourage the indulgence in vain procedures for controlling the universe, instead of the profitable application of developing a technique for specific ends; to substitute unreal for real achievement, imagination for action, and to breed an easy fatalism which will prevent the building of fences to keep off crocodiles, or the taking of suitable measures to prevent disease. . . . Magic is indeed a parasitic adjunct to technique which sometimes completely immobilizes it.

China is Right about Who Should Pay for Carbon Emissions

In the runup to a new round of negotiations on a global climate agreement, China is calling for a “consumer pays” principle: those who import goods from China should pay for their embedded carbon emissions. According to this Reuters Report, Gao Li, the top Chinese official for climate change policy says, “About 15 percent to 25 percent of China's emissions come from the products which we make for the world....this share of emission should be taken by the consumers, not the producers.”

This is not only correct, it is the natural outcome of a rational climate policy regime.



Suppose China requires anyone introducing a carbon fuel into its economy, such as an oil, gas or coal company, to have a permit, and that it caps these permits to curb emissions. Prices of the fuels rise, and these prices are passed along to direct consumers including manufacturers who use these fuels as inputs. This in turn means that prices rise for the manufactured products, paid by the ultimate consumers—in this case, often US and European importers.

If all the permits are auctioned, their combined value will approximately equal the extra revenues derived from consumers. The government could then rebate this money back to its citizens. Since China is a net exporter (even during the current crisis), the money received by its households will exceed the money they pay in higher prices. This means China could, if it wished, rebate somewhat less than the total auction proceeds, use its cut to finance investments in energy efficiency and non-carbon alternatives, and still protect the real income of its population.

This process, which meets the conditions laid down by Li, can be set in motion by the Chinese themselves, unilaterally. The only need for international coordination concerns the problem of leakage, i.e. how to prevent Chinese domestic and export markets from being captured by producers in countries that don’t require carbon permits. The first-best solution would a global agreement to require permits everywhere with a single, global cap. Such permits would be universally tradeable, which means that artificial barriers to their efficient allocation would be removed. Since there would be a single global price, the leakage problem would be eliminated too.

A second-best approach would be to institute a system of border taxes calibrated to the differences in production costs stemming from different national carbon regimes. Establishing a common set of procedures for calculating and applying this tax should be a high priority for negotiators.

Developing countries with trade surpluses, and particularly China, should be eager to enter a system of carbon emission controls. The rest of the developing world will need other inducements.

Leftist Econophysics

There is a branch of econophysics that has attracted serious attention from some Marxist and other leftist economists. This is the series of studies of income and wealth distributions. Traditionally income has been thought to reflect lognormal distributions, which can arise endogenously from random processes from an initially equal distribution. In fact, labor income appears to follow such a pattern. However, wealth appears to follow the power law distributions of financial asset returns, unsurprisingly, that have fatter tails than lognormal distributions, that is, greater inquality with more people far off into the upper end of the distribution. Econophysics studies of this began around a decade ago, appearing in places like Physica A and European Physical Journal B by people like Levy and Solomon and also Dragulescu and Yakovenko, although John Angle showed some of the things in the early 1990s in the Journal of Mathematical Sociology.

Then it was figured out by people like Yakovenko and some others that income distribution looks lognormal for most of its lower portion, where it is determined by labor outcomes, but that its upper portion looks more like a more unequal power law, a la wealth and financial market returns. The class nature of this then began attracting the attention of some leftist economists such as Allin Cottrill and Paul Cockshott, who have now coauthored a book, Classical Econophysics, with Gregory John Michaelson, Ian P. Wright, and Victor Yakovenko. More of these studies, some done by economists such as Mauro Gallegati and some of his coauthors, including some physicists, have appeared in the 2005 book, Econophysics of Wealth Distributions, ed. by Chatterjee, Yagarladda, and Chakrabarti, Milan: Springer.

Outside of the Vortex

Parts of Australia are experiencing unprecedented changes in temperature and rainfall patterns. These changes are associated with an unexpected phenomenon emerging in the Indian Ocean and also in the behaviour of the Antarctic Vortex combined with steadily increasing temperatures from rising greenhouse gases and the depletion of the ozone layer. Observed together they suggest the very strong possibility that Australians are now facing abrupt climate change.[1] This is bringing very prolonged drought and extraordinary heat to the most heavily peopled and treed (mostly Eucalypt) regions of the country. As if this prospect is not frightening enough, it can be seen that climate is not the only threshold that is being crossed. The flashpoint for eucalypt vapour is also being breached by high daytime temperatures. This appears to guarantee the setting off of huge fire infernos in these semi-urban ‘forests’ on a scale that many would simply not be able to imagine.

Southeast Australia has been suffering from a drought over the last 15 years that is of an intensity that has not (as far as we are aware) been experienced before. This has left the landscape very dry. Climatologist Caroline Ummenhofer, a research fellow with the University of New South Wales says that “normally drought conditions over eastern Australia are associated with El Nino, La Nina cycles in the Pacific Ocean (temperature changes that affect the rainfall and circulation over the whole Pacific Ocean and the surrounding areas).” [2]

However, “El Nino is not able to explain this latest drought” says Ummenhofer. “Instead what we found is actually that the cause lies in Indian Ocean temperatures.” “The Indian Ocean has a similar phenomenon to the El Nino, La Nina cycle. It's called the Indian Ocean Dipole, and it's a naturally occurring phenomenon and has been known for some time to influence Australian climate and Australian weather. The dipole oscillates between positive and negative phases and has neutral years in between as well, so the negative and the positive are the two extremes. And the normal wet conditions that you experience over south-east Australia are linked to the negative Indian Ocean dipole event which we haven't seen over the last seventeen years…..the last India Ocean Dipole event of the negative phase occurred in 1992. That is unusual. We haven't anywhere in the record over the last 120 years that we've investigated seen a similarly prolonged period without a single negative event”

Ummenhofer observes that most of the world’s oceans are getting warmer, but particularly the Indian Ocean. “There might be indications that this could lead to changes in the characteristics of Indian Ocean dipole events.” [3]

The Antarctic Vortex near the South Pole is, like its equivalent in the Arctic pole region, a persistent, large-scale cyclone in the middle and upper troposphere and the stratosphere. Polar vortexes are most powerful in the hemisphere's winter, when the temperature gradient is steepest, and diminishes or can disappear in the summer. [4]

The Intergovernmental Panel on Climate Change Third Assessment Report incorporated a chapter [5] on ‘radiative forcing’[6] which noted “several … anthropogenic [man-made] causes for global climate change” These factors, that could be interacting with each other, including rising concentrations of greenhouse gases, the effects of man-made particulates in the atmosphere, and ozone depletion in the stratosphere.

The IPCC noted that scientific studies on these ‘forcings’ observed that the radiative effects of aerosols circulating in the atmosphere, whilst being largely confined to the Northern Hemisphere, may “propagate into the Southern Hemisphere via atmospheric dynamics”. In addition to this, the polar vortex in both the north and south hemispheres were strengthened and the westerly winds in the mid latitudes were contracting and thus moving closer to the poles. These changes, the report noted, may be arising from the rising greenhouse gas concentrations as well as from ozone depletion in the stratosphere.

The implications behind the fact that the westerly winds are moving closer to Antarctica are quite frightening for Australians. “it appears the vortex is shifting gear, and is spinning faster and faster, and getting tighter. As it does it’s pulling the climate bands further south dragging rain away from the continent out into the southern ocean.” [7]. In short, it means that Australia’s unprecedented and horrific drought may not go away!

Climate (like other complex systems) does not behave in a simple linear fashion. That is, simple linear extrapolation is not always possible. Sudden changes in a regime (such as rainfall) can occur over wide areas. This is what’s happened over Australia, even before the 1992 Indian Ocean dipole shift and the contraction of the southern vortex. Around 1945 Australia’s summer half-year rainfall increased over large areas in the eastern part of the continent. However, in 1967-72 there was a sudden decrease in rainfall in south-west of Western Australia which has not reversed since. [8] “Now the same thing is happening to Melbourne.” In 2003 rainfall there had fallen by nearly 20% in the previous 7 years. [7] This dangerous pattern has continued and, at present, almost every mainland capital city is on increasingly severe water restrictions.

Similar examples of sudden changes in system behaviour often arise from an element of the system reaching a limit or threshold at which instability sets in, and the system moves into a new stable state. When the system is close to a threshold even quite small random events or trends can force the system into a different state. Distance from a threshold of this sort is a measure of system resilience or ability to cope with small variations in conditions (Scheffer et al., 2001). [9]

So, indeed it does look like Australia is going through abrupt and dangerous climate change right now.

One very important question comes immediately to mind. How resilient is Australia’s society and infrastructure now? Are they ready to deal with the biggest challenge in the nation’s history? After the most horrific fires ever recorded? After 15 years of intense heat and drought?

What other thresholds, apart from climate-related ones, are Australians dealing with? One critical and almost entirely overlooked threshold is the flashpoint for eucalyptus oil. “The flash point of a flammable liquid is the lowest temperature at which there can be enough flammable vapour to ignite, when an ignition source is applied.” [10] The ‘flash point’for the vapours that rise from Australia’s ubiquitous native trees is a mere 49 degrees Celsius. On Black Saturday this year [11] the temperatures, in the shade, were around 47 degrees Celsius. In the full sun, however, temperatures are about 5-6 Celsius degrees hotter!

Another threshold associated with industrial tree plantations is the level of fuel loads that are amenable to control by our fire departments. The Canberra fire chief reported, soon after that city’s plantation fires encroached and burnt out hundreds of houses in this urban environment, that the fuel load in tree plantations 3-7 years of age was the limit reached before the fires could be brought under control. [12]

Those individuals living in southern Australia have every reason – whether they know it or not - to feel horrified by their prospects for next summer and for many summers after that. After all, “the past decade has recorded the largest expansion ever in [Eucalypt niten and Radiata pine tree] plantation cover in this country” with an average annual planting of 76,000 hectares per year since 1997. [13],[14]. “The majority…is concentrated along the southern and eastern coasts, Tasmania and Western Australia.” [15].

Up until ‘Black Saturday’ Australians had been lulled into a false sense of security. Many families had no knowledge of the need for fire plans or of local geography as “ the hottest day on record on top of the driest start to a year on record on top of the longest driest drought on record on top of the hottest drought on record” approached. [16] Residents are largely oblivious to the enormous hazards the intense and ubiquitous plantings of Eucalypt and Radiata pine monocultures pose to their safety. Residents of the burnt out Victorian township of Marysville saw “what looked like an atomic bomb”[17] coming over the top of the town but had no idea as to the nature of its genesis.

But the truth is that the Black Saturday fires entailed the convergence of two huge fire balls that erupted in a tree plantation estate at East Kilmore and joined with another fire front that appeared to begin at a timber mill in the Murrindindi complex of heavily logged native forest and extensive industrial tree plantations further east [18] [19]. “A two-kilometre stretch of power line in Kilmore East … snapped during strong winds and record heat about 11am last Saturday [7th February 2009]. Within minutes a nearby pine forest was ablaze. Within six hours the fire had destroyed nearly every building in the towns in its path….”[20] . Around 4pm the Victorian Country Fire Authority (CFA) had advised the public that “the fire [was] gaining strength as it head[ed] towards pine plantations near Wandong” [21]where a large bluegum plantation lay within a kilometer of the town. [22] Within 12 hours an ominous line of closely spaced fire fronts stretched all the way from very large East Kilmore/Murrindindi merged inferno through the Bunyip State Forest down to Druoin and Warragul; to within approximately 40 kilometres of the other very large fire complexes around Churchill. The Churchill fire, in turn, began one kilometre south-east of the town in a pine plantation. The flames, out of control, spread rapidly, threatening communities in Hazelwood South and the Jeeralangs. Traralgon South, Callignee, Woodside, Yarram, Carrjung, Gormandale and many more communities came under threat….”[23].

“We have seen the future” says Clive Hamilton. [24]. Some people ask whether Australians will continue to survive living within our tall Eucalypt forest digs. Perhaps the real forests will survive, though the trees may change; become stunted and sparse. With a few more fires the ugly industrial tree plantations will surely disappear. The surviving human residents will learn from the wombat and go underground.

[1] “…A working definition of 'abrupt climate change' is given in Alley et al. (2002): ‘technically, an abrupt climate change occurs when the climate system is forced to cross some threshold, triggering a transition to a new state at a rate determined by the climate system itself and faster than the cause’.

[2] The El Nino Southern Oscillation (ENSO) is a particular pattern of disruption in the interaction between the ocean and the atmosphere that occurs every two to seven years when strong westward-blowing trade winds over the Pacific ocean subside and warm western Pacific water slowly moves back eastward. The upwelling of the cool, nutrient rich, eastern Pacific water (that supports large fish populations) is interrupted. When this happens fish die and climatic changes kick in that affect many parts of the planet. The possible interrelationship between El Nino and the simultaneous droughts on the Australian and other continents was first realized in 1972-73. See:

The change is computed based on "unperturbed" values, as defined by the Intergovernmental Panel on Climate Change (IPCC) as the measured difference relative to the year 1750, the defined starting point of the industrial era. A positive forcing (more incoming energy) tends to warm the system, while a negative forcing (more outgoing energy) tends to cool it.

WaPo Still Hoping to Mess With Social Security

Fred Hiatt is the editorial page editor of the Washington Post. In the March 16 issue he actually has a signed column praising the Obama approach to transportation policy. In the midst of this he also writes, "maybe we can hope for reform of social security and health care too." While we need reform of health care, we do not need it for social security, and the WaPo editorial page, and just about all its regular columnists, have been among the most consistent trumpeters of the "social security is in crisis!" baloney that just persists and persists in Washington, with them also pushing the theme of "entitlements crisis," viewing social security as in the same league as health care.

Fortunately, after worries that Obama was buying into this baloney with his "Entitlements Summit," it increasingly appears that he is reverting to his campaign position of not wanting to do anything to social security, or at least not wanting to do anything to the benefits side, with the key player on this being probably Peter Orszag, OMB Chief, who has made it clear that the real problem is indeed health care. As for social security, what I have said umpteen gazillion times still holds: it ain't broke and it don't need no fixin'.

Obama Budget: Mankiw Rehashes Old Spin

Greg Mankiw calls President Obama a deficit dove who loves to spend. Mankiw also accuses the White House of economic optimism:

they expect their policies to bring the recession to a swift conclusion. For the next four years, they forecast an average growth rate of 4 percent. The unemployment rate is projected to fall to 5.2 percent in 2013.Not everyone is so sanguine. The administration forecast is “way too optimistic,” said Nariman Behravesh, chief economist at IHS Global Insight and author of the excellent primer “Spin-Free Economics.”

OK – if one expects the recession to be deeper and more prolonged than the White House, why would one be upset that the White House is pursuing fiscal stimulus? Mankiw’s economic pessimism and his call for a more deficit hawk position strikes me as inconsistent.

Mankiw also repeats this line:

In a second term for Mr. Obama, with the economy recovered and unemployment stabilized at 5 percent, federal outlays would be 22.2 percent of G.D.P. — well above the average of 20.2 percent over the last 50 years.

Didn’t we already address this claim with:

A New Era of Responsibility - Renewing America’s Promise does show that the projected Federal outlay to GDP ratio for 2019 under President Obama’s proposed changed in the budget will be 22.6% as Greg claims but what Greg did not tell us is that the baseline budget projected Federal outlays to be 23.2% of GDP by 2019.

Update: The deficit hawks at the Concord Coalition does not agree with Mankiw’s deficit dove characterization:

A further complication is that many of the budget’s main components are linked in an effort to control the net effect on the deficit. Maintaining this linkage is critical for fiscal responsibility. However, it will prove to be a formidable political hurtle because it challenges the free lunch mentality that has taken root in Washington. New initiatives, popular with many Congressional leaders, are paired with tax increases and spending cuts that are not as popular ... Nothing in the budget directly alters the drift toward fiscal unsustainability, which is primarily driven by the projected growth of the three largest entitlement programs -- Medicare, Medicaid and Social Security. Under the budget, spending on these programs declines by just $32 billion relative to baseline assumptions through 2019 ... As the president acknowledges, any effort to permanently improve the fiscal outlook beyond the 10-year budget window will require more fundamentally addressing the structural causes of the long-term imbalance -- demographic changes and rising health care costs. While there is plenty of room to debate the priorities, assumptions, and details, it cannot be said that the Obama administration has taken a timid approach in its first budget. It confronts a broad array of challenges and does not pretend that we can have something for nothing.

While the Concord Coalition goes onto to note several factors that might work against President’s goal of long-term fiscal restraint, it is much more informative and balanced than Mankiw’s spin.

Grasping Reality with Both Hands Bound to the Standard Model

by the Sandwichman

Brad DeLong meanders out to the edge of the abyss of knowing but at the last minute pulls back in horror, clutching his standard model teddy bear to his breast...

The 1929-1950 period saw the last sharp decline in the American workweek--a decline that does not mean that the economy was depressed and performing poorly in 1959 or 1949 (or 1939) relative to 1929, but instead that Americans had decided to take a substantial part of their increased technological wealth and use it to buy increased leisure.

Can you say A-N-A-C-H-R-O-N-I-S-M? The 1929-1950 period did indeed see the last sharp decline in the American workweek. But in what sense did Americans choose to buy increased leisure? They were, first of all, compelled by hardship to reduce their hours of work. They only chose shorter hours through work-sharing as an alternative to even greater unemployment. Secondly, Americans chose to legislatively impose shorter hours through the Fair Labor Standards Act. And if it wasn't for the strident objection of business they would have chosen the even shorter 30-hour workweek of the Black Connery bill. But the income/leisure choice standard model that Brad invokes doesn't approve of the imposition of shorter hours by legislation.

A second anomaly in Brad's historical interpretation that Americans decided to take increased wealth as leisure is that this choice mysteriously stopped occurring after the 1950s even though wealth continued to increase vigorously. Funny (peculiar) Americans somehow choose to take more of their "increased wealth" as leisure precisely at the time their wealth is decreasing precipitously and then choose not to take it as leisure when their wealth is actually increasing.

Wait a minute! Did I say Americans chose to take their increased wealth as leisure when their wealth was actually decreasing? But the standard model says... Can somebody help me out here? If wealth is decreasing, in what sense is it "increasing"? Brad?

"...Americans had decided to take a substantial part of their increased technological wealth and use it to buy increased leisure..."

I'm sure the math explains it double-plus good, though.

I do agree with Brad, however, that the sharp decline in the workweek, 1929-1950 was a good thing, at least in retrospect. Sometimes bad circumstances can impose necessities that turn out to be blessings. In this case, I would like to see an economist take on the proposition that the sharp decline in the workweek during the 1929-1950 period established a strong foundation upon which the post-war economy was built. I would love to see Brad DeLong or Paul Krugman take it on.

That hypothesis, by the way, is consistent with Keynes's view of the long-term problem of full employment and with Chapman's theory of the hours of labour.

If a sharp decline in the workweek can be (part of) the foundation of one exceptional period of prosperity, who is to say that another sharp decline in the workweek couldn't be part of the solution to the current crisis? For example, see Dean Baker's proposal for work time reduction as stimulus.

Please discuss.

X-Efficiency and Economic Dogma

I just added a draft -- quickly composed today -- of section to put in my new book. It will go into a section showing the lengths to which economists would go to avoid dealing with work, workers, and working conditions. This is one of the episodes where economists risked dealing with the subject. Any comments would be very much appreciated.

Thank you very much

Washington Times on Long-term Growth Rates

The Washington Times tries to ridicule Paul Krugman:

Harvard economics Professor Greg Mankiw thinks that Mr. Obama's growth forecasts are overly optimistic and that the federal deficit will be a lot larger than Mr. Obama thinks. He was chastised by Princeton's Paul Krugman, a Nobel Prize winner in economics, who on his New York Times blog claims that Mankiw can only make the predictions that he does because of "more than a bit of deliberate obtuseness." He titled his post on Mankiw, "Roots of Evil." Last Wednesday, Mankiw responded to Krugman's attacks by suggesting: "Well, Paul, if you are so confident in this forecast, would you like to place a wager on it and take advantage of my wickedness?" Krugman has still not responded. It seems even a Nobel Prize winner isn't willing to lay money on Mr. Obama's rosy projections.

I’m not sure why one would be waging a bet against the US economy in the first place but I don’t blame Professor Krugman for ignoring this silliness. Speaking of silliness, the Washington Times lead this pathetic op-ed with:

The Obama administration is basing its budget forecasts on the economy growing an eyebrow-raising 15.6 percent above inflation between 2008 and 2013 - a drop of 1.2 percent this year followed by an average of 4 percent growth over the following four years. That's very impressive growth for any period of time.

So for the first five years, the Obama administration is forecasting a growth rate less than 3 percent – which would mean that its forecast for a 9-year interval would have average annual growth that is less than 3.5 percent. Did the author of this op-ed not realize that the average annual growth rate for the last half of the 20th century was about 3.5 percent?

Health Care Costs for Employers: Amity Shlaes v. Greg Mankiw

Steve Benen has a little fun with the latest nonsense from Amity Shlaes:

I'm a big science-fiction fan, so when I heard that conservative writer and FDR critic Amity Shlaes had compared contemporary politics to "The Matrix," I was anxious to see what she'd come up with.

But it was this claim that caught my eye:

Take one of the biggest problems in the U.S. economy today: jobs. Long before “subprime” or “cram down” became routine components of our language, we understood that employers need incentives to create new jobs to replace ones that are disappearing. We knew too that health-care costs are a growing deterrent to hiring or rehiring. Between 1996 and 2005 health care costs for employers rose by 34 percent relative to payrolls.

Didn’t Greg Mankiw and Doug Elmendorf suggest that this cost is fully passed onto workers in the form of lower wages? While I suggested that this may be an extreme assumption as to the lack of elasticity of the labor supply curve (see this post), Shlaes is arguing that none of these costs are passed onto workers in the form of lower wages. Maybe she should have read her own source:

Most economists believe that health insurance premium costs are ultimately passed back to employees in the form of reduced wages, so long-run compensation costs for employers are not affected by rising health care prices.
