Secular stagnation III –minus the irony

flattr this!

I'm sorry, I couldn't help it: when Larry Summers first made his secular stagnation speech at the IMF, and the American economics tribe heralded it as if it were the greatest (and latest) thing since sliced bread, my irony gene went into overload—and that showed in my first post on the topic. The argument that the West has been suffering from secular stagnation, and that only a series of financial bubbles have kept the illusion of prosperity going, has been part of non-orthodox economics for over three decades.

Much of this has been in the real underworld of economics, emanating from the handful of avowedly Marxist economists that have survived in academic institutions and non-mainstream media. But issues such as the impact of transnational corporations relocating production to third world free trade zones have been hot topics amongst non-mainstream economists for decades (for instance, I wrote my first piece on this topic in 1979—here's the somewhat dated Technical Appendix for wonks).

Back then. the reaction of mainstream economists to this perspective was at best a deafening silence, and at worst derision. Weren't these the lefties who were always expecting the final crisis of capitalism, even after the fall of the Berlin Wall?

Of course, there was more than a grain of truth to that riposte. But rather than tackling the secular stagnation arguments directly, mainstream economists dismissed them with derision, in the sublime confidence that capitalism could never have crises. My favorite such statement was by Edward Prescott (who, with Finn Kydland got the Nobel Prize for inventing the "real business cycle, representative agent" approach to economics that still dominates the mainstream today). Entitled "Some obser­va­tions on the Great Depression” and writ­ten in 1999, it con­cluded with this rhetor­i­cal flourish:

 The Marx­ian view is that cap­i­tal­is­tic economies are inher­ently unsta­ble and that exces­sive accu­mu­la­tion of cap­i­tal will lead to increas­ingly severe eco­nomic crises. Growth the­ory, which has proved to be empir­i­cally suc­cess­ful, says this is not true. The cap­i­tal­is­tic econ­omy is sta­ble, and absent some change in tech­nol­ogy or the rules of the eco­nomic game, the econ­omy con­verges to a con­stant growth path with the stan­dard of liv­ing dou­bling every 40 years. (Prescott 1999)

Yeah, right. One decade later, that open­ing Marx­ist sen­tence began to sound a lot more real­is­tic than Prescott’s dis­missal of it.

Of course, main­stream econ­o­mists could never acknowl­edge the prior argu­ments of a rival intel­lec­tual tra­di­tion, but now that Larry (peace be upon him) Sum­mers has said it, sud­denly it’s OK to spout what the left­ies have been say­ing for 30 years (though with dif­fer­ent expla­na­tions, of course—it’s declin­ing pop­u­la­tion growth and falling lev­els of inno­va­tion, not nasty transna­tion­als relo­cat­ing pro­duc­tion, or finan­cial­iza­tion of the econ­omy white-anting the indus­trial sector).

Oh give me a break—hence the irony. But since Sum­mers’ take on sec­u­lar stag­na­tion looks like it will be the flavour of the month for Amer­i­can econ­o­mists for the fore­see­able future, I have to take it more seri­ously. Hence this more seri­ous post for my first col­umn in 2014, which builds on the last two on this topic—and with no irony whatsoever.

But I’ll com­mence with two caveats: yes sec­u­lar stag­na­tion is real, but it has far more to do with rea­sons the main­stream has always rejected than with any­thing it will dream up post-Summers; and the left­ies got there first.

That said, let’s get aca­d­e­mic over how “secular-stagnation-augmented Loan­able Funds” might allow Neo­clas­si­cals to take pri­vate debt seri­ously some of the time…

The cri­sis of 2007/08 has gen­er­ated many anom­alies for con­ven­tional eco­nomic the­ory, not the least that it hap­pened in the first place. Though main­stream eco­nomic thought has many chan­nels, the com­mon belief before this cri­sis was that either crises can­not occur (Edward C. Prescott, 1999), or that the odds of such events had either been reduced (Ben Bernanke, 2002) or elim­i­nated (Robert E. Lucas, Jr., 2003) cour­tesy of the sci­en­tific under­stand­ing of the econ­omy that main­stream the­ory had developed.

This anom­aly remains unre­solved, but time has added another that is more press­ing: the fact that the down­turn has per­sisted for so long after the cri­sis. Recently Larry Sum­mers sug­gested a fea­si­ble expla­na­tion in a speech at the IMF. “Sec­u­lar stag­na­tion”, Sum­mers sug­gested, was the real expla­na­tion for the con­tin­u­ing slump, and it had been with us for long before this cri­sis began. Its vis­i­bil­ity was obscured by the Sub­prime Bub­ble, but once that burst, it was evident.

This hypoth­e­sis asserts, in effect, that the cri­sis itself was a second-order event: the main event was a ten­dency to inad­e­quate pri­vate sec­tor demand which may have existed for decades, and has only been masked by a sequence of bub­bles. The pol­icy impli­ca­tion of this hypoth­e­sis is that gen­er­at­ing ade­quate demand to ensure full employ­ment in the future may require a per­ma­nent stim­u­lus from the gov­ern­ment – mean­ing both the Con­gress and the Fed – and per­haps the reg­u­lar cre­ation of asset mar­ket bubbles.

What could be caus­ing the sec­u­lar stag­na­tion – if it exists? Krug­man (Paul Krug­man, 2013b) noted a cou­ple of fac­tors: a slow­down in pop­u­la­tion growth (which is obvi­ously hap­pen­ing: see Fig­ure 1); and “a Bob Gor­donesque decline in inno­va­tion” (which is rather more conjectural).

Though Sum­mers’ the­sis has its main­stream crit­ics, there’s a cho­rus of New Key­ne­sian sup­port for the “sec­u­lar stag­na­tion” argu­ment, which implies it will soon become the con­ven­tional expla­na­tion for the per­sis­tence of this slump long after the ini­tial finan­cial cri­sis has passed.

Krugman’s change of tune here is rep­re­sen­ta­tive. His most recent book-length foray into what caused the cri­sis – and what pol­icy would get us out of it – was enti­tled End This Depres­sion NOW!. The title, as well as the book’s con­tents, pro­claimed that this cri­sis could be ended “in the blink of an eye”. All it would take, Krug­man then pro­posed, was a suf­fi­ciently large fis­cal stim­u­lus to help us escape the “Zero Lower Bound”:

The sources of our suf­fer­ing are rel­a­tively triv­ial in the scheme of things, and could be fixed quickly and fairly eas­ily if enough peo­ple in posi­tions of power under­stood the realities…

One main theme of this book has been that in a deeply depressed econ­omy, in which the inter­est rates that the mon­e­tary author­i­ties can con­trol are near zero, we need more, not less, gov­ern­ment spend­ing. A burst of fed­eral spend­ing is what ended the Great Depres­sion, and we des­per­ately need some­thing sim­i­lar today. (Paul Krug­man, 2012, pp. 23, 231)

Fig­ure 1: Pop­u­la­tion growth rates are slowing

Post-Summers, Krug­man is sug­gest­ing that a short, sharp burst of gov­ern­ment spend­ing will not be enough to restore “the old nor­mal”. Instead, to achieve pre-crisis rates of growth in future – and pre-crisis lev­els of unem­ploy­ment – per­ma­nent gov­ern­ment deficits, and per­ma­nent Fed­eral Reserve spik­ing of the asset mar­ket punch via QE and the like, may be required.

Not only that, but past appar­ent growth suc­cesses – such as The Period Pre­vi­ously Known as The Great Mod­er­a­tion– may sim­ply have been above-stagnation rates of growth moti­vated by bubbles:

So how can you rec­on­cile repeated bub­bles with an econ­omy show­ing no sign of infla­tion­ary pres­sures? Summers’s answer is that we may be an econ­omy that needs bub­bles just to achieve some­thing near full employ­ment – that in the absence of bub­bles the econ­omy has a neg­a­tive nat­ural rate of inter­est. And this hasn’t just been true since the 2008 finan­cial cri­sis; it has arguably been true, although per­haps with increas­ing sever­ity, since the 1980s. (Paul Krug­man, 2013b)

This argu­ment ele­vates the “Zero Lower Bound” from being merely an expla­na­tion for the Great Reces­sion to a Gen­eral The­ory of Macro­eco­nom­ics: if the ZLB is a per­ma­nent state of affairs given sec­u­lar stag­na­tion, then per­ma­nent gov­ern­ment stim­u­lus and per­ma­nent bub­bles may be needed to over­come it:

One way to get there would be to recon­struct our whole mon­e­tary sys­tem – say, elim­i­nate paper money and pay neg­a­tive inter­est rates on deposits. Another way would be to take advan­tage of the next boom – whether it’s a bub­ble or dri­ven by expan­sion­ary fis­cal pol­icy – to push infla­tion sub­stan­tially higher, and keep it there. Or maybe, pos­si­bly, we could go the Krug­man 1998/Abe 2013 route of push­ing up infla­tion through the sheer power of self-fulfilling expec­ta­tions. (Paul Krug­man, 2013b)

So is sec­u­lar stag­na­tion the answer to the puz­zle of why the econ­omy hasn’t recov­ered post the cri­sis? And is per­ma­nently blow­ing bub­bles (as well as per­ma­nent fis­cal deficits) the solution?

Firstly there is ample evi­dence for a slow­down in the rate of eco­nomic growth over time – as well as its pre­cip­i­tate fall dur­ing and after the crisis.

Fig­ure 2: A sec­u­lar slow­down in growth caused by a sec­u­lar trend to stag­na­tion?

The growth rate was as high as 4.4% p.a. on aver­age from 1950–1970, but fell to about 3.2% p.a. from 1970–2000 and was only 2.7% in the Naugh­ties prior to the cri­sis – after which it has plunged to an aver­age of just 0.9% p.a. (see Table 1).

Table 1: US Real growth rates per annum by decade

Start End Growth rate p.y. for decade Growth rate since 1950
1950 1960 4.2 4.2
1960 1970 4.6 4.4
1970 1980 3.2 4
1980 1990 3.1 3.8
1990 2000 3.2 3.7
2000 2008 2.7 3.5
2008 Now 0.9 3.3

 

So the sus­tained growth rate of the US econ­omy is lower now than it was in the 1950s–1970s, and the undoubted demo­graphic trend that Krug­man nom­i­nates is clearly one fac­tor in this decline.

Another fac­tor that Krug­man alludes to in his post is the rise in house­hold debt dur­ing 1980–2010 – which at first glance is incom­pat­i­ble with the “Loan­able Funds” model of lend­ing to which he sub­scribes. In the Loan­able Funds model, the aggre­gate level of debt (and changes in that level) are irrel­e­vant to macro­eco­nom­ics – only the dis­tri­b­u­tion of debt can have significance:

Ignor­ing the for­eign com­po­nent, or look­ing at the world as a whole, we see that the over­all level of debt makes no dif­fer­ence to aggre­gate net worth – one person’s lia­bil­ity is another person’s asset. It fol­lows that the level of debt mat­ters only if the dis­tri­b­u­tion of net worth mat­ters, if highly indebted play­ers face dif­fer­ent con­straints from play­ers with low debt. (Paul Krug­man,
2012a, p. 146)

Fur­ther­more, the dis­tri­b­u­tion of debt can only have macro­eco­nomic sig­nif­i­cance at pecu­liar times, when the mar­ket mech­a­nism is unable to func­tion because the “nat­ural rate of inter­est” – the real inter­est rate that will clear the mar­ket for Loan­able Funds, and lead to zero infla­tion with other mar­kets (includ­ing labor) in equi­lib­rium – is negative.

Prior to Sum­mers’ the­sis, Krug­man had argued that this pecu­liar period began in 2008 when the econ­omy entered a “Liq­uid­ity Trap”. Pri­vate debt mat­ters dur­ing a Liq­uid­ity Trap because lenders, wor­ried about the capac­ity of bor­row­ers to repay, impose a limit on debt that forces bor­row­ers to repay their debt and spend less. To main­tain the full-employment equi­lib­rium, peo­ple who were once lenders have to spend more to com­pen­sate for the fall in spend­ing by now debt-constrained borrowers.

But lenders are patient peo­ple, who by def­i­n­i­tion have a lower rate of time pref­er­ence than bor­row­ers, who are impa­tient people:

Now, if peo­ple are bor­row­ing, other peo­ple must be lend­ing. What induced the nec­es­sary lend­ing? Higher real inter­est rates, which encour­aged “patient” eco­nomic agents to spend less than their incomes while the impa­tient spent more. (Krug­man, “Delever­ag­ing and the Depres­sion Gang”)

The prob­lem in a Liq­uid­ity Trap is that rates can’t go low enough to encour­age patient agents to spend enough to com­pen­sate for the decline in spend­ing by now debt-constrained impa­tient agents.

You might think that the process would be sym­met­ric: debtors pay down their debt, while cred­i­tors are cor­re­spond­ingly induced to spend more by low real inter­est rates. And it would be sym­met­ric if the shock were small enough. In fact, how­ever, the delever­ag­ing shock has been so large that we’re hard up against the zero lower bound; inter­est rates can’t go low enough. And so we have a per­sis­tent excess of desired sav­ing over desired invest­ment, which is to say per­sis­tently inad­e­quate demand, which is to say a depres­sion. (Krug­man, “Delever­ag­ing and the Depres­sion Gang”)

After Sum­mers, Krug­man started to sur­mise that the econ­omy may have been expe­ri­enc­ing sec­u­lar stag­na­tion since 1985, and that only the rise in house­hold debt masked this phe­nom­e­non. Con­se­quently the level and rate of change of pri­vate debt could have been macro­eco­nom­i­cally sig­nif­i­cant not merely since 2008, but since as long ago as 1985.

Fig­ure 3: Ratio of house­hold debt to GDP

Com­ment­ing on the data (Fig­ure 3, sourced from the St Louis Fed’s excel­lent FRED data­base, is taken from Krugman’s post), Krug­man noted that per­haps the increase in debt from 1985 on masked the ten­dency to sec­u­lar stag­na­tion. Cru­cially, he pro­posed that the “nat­ural rate of inter­est” was neg­a­tive per­haps since 1985, and only the demand from bor­row­ers kept actual rates pos­i­tive. This in turn implied that, absent bub­bles in the stock and hous­ing mar­kets, the econ­omy would have been in a liq­uid­ity trap since 1985:

There was a sharp increase in the ratio after World War II, but from a low base, as fam­i­lies moved to the sub­urbs and all that. Then there were about 25 years of rough sta­bil­ity, from 1960 to around 1985. After that, how­ever, house­hold debt rose rapidly and inex­orably, until the cri­sis struck.

So with all that house­hold bor­row­ing, you might have expected the period 1985–2007 to be one of strong infla­tion­ary pres­sure, high inter­est rates, or both. In fact, you see nei­ther – this was the era of the Great Mod­er­a­tion, a time of low infla­tion and gen­er­ally low inter­est rates. With­out all that increase in house­hold debt, inter­est rates would pre­sum­ably have to have been con­sid­er­ably lower – maybe neg­a­tive. In other words, you can argue that our econ­omy has been try­ing to get into the liq­uid­ity trap for a num­ber of years, and that it only avoided the trap for a while thanks to suc­ces­sive bubbles.

In gen­eral, the Loan­able Funds model denies that pri­vate debt mat­ters macro­eco­nom­i­cally, as Krug­man put it emphat­i­cally in a series of blog posts in 2012:

Keen then goes on to assert that lend­ing is, by def­i­n­i­tion (at least as I under­stand it), an addi­tion to aggre­gate demand. I guess I don’t get that at all. If I decide to cut back on my spend­ing and stash the funds in a bank, which lends them out to some­one else, this doesn’t have to rep­re­sent a net increase in demand. Yes, in some (many) cases lend­ing is asso­ci­ated with higher demand, because resources are being trans­ferred to peo­ple with a higher propen­sity to spend; but Keen seems to be say­ing some­thing else, and I’m not sure what. I think it has some­thing to do with the notion that cre­at­ing money = cre­at­ing demand, but again that isn’t right in any model I under­stand. (Paul Krug­man, 2012b. Empha­sis added).

How­ever, the Sum­mers con­jec­ture pro­vides a means by which pri­vate debt could assume macro­eco­nomic sig­nif­i­cance since 1985 within the Loan­able Funds model. Once sec­u­lar stag­na­tion com­menced – dri­ven, in this con­jec­ture, by the actual drop in the rate of growth of pop­u­la­tion and a hypoth­e­sized decline in inno­va­tion – the econ­omy was effec­tively in a liq­uid­ity trap, and some­how ris­ing debt hid it from view.

That is the broad brush, but I expect that explain­ing this while remain­ing true to the Loan­able Funds model will not be an easy task—since, like a Liq­uid­ity Trap itself, the Loan­able Funds model is not sym­met­ric. Whereas Krug­man was able to explain how pri­vate debt causes aggre­gate demand to fall when debt is falling and remain true to the Loan­able Funds model (in which banks are mere inter­me­di­aries and both banks and money can be ignored – see Gauti B. Eggerts­son and Paul Krug­man, 2012), it will be much harder to explain how debt adds to aggre­gate demand when it is ris­ing. This case is eas­ily made in an Endoge­nous Money model in which banks cre­ate new spend­ing power, but it fun­da­men­tally clashes with Loan­able Funds in which lend­ing sim­ply redis­trib­utes exist­ing spend­ing power from lenders to bor­row­ers. Nonethe­less, Krug­man has made such a state­ment in a post-Summers blog:

Debt was ris­ing by around 2 per­cent of GDP annu­ally; that’s not going to hap­pen in future, which a naïve cal­cu­la­tion sug­gests means a reduc­tion in demand, other things equal, of around 2 per­cent of GDP. (Paul Krug­man, 2013a)

If he man­ages to pro­duce such a model, and if it still main­tains the Loan­able Funds frame­work, then the model will need to show that pri­vate debt affects aggre­gate demand only dur­ing a period of either sec­u­lar stag­na­tion or a liq­uid­ity slump – oth­er­wise the secular-stagnation-augmented Loan­able Funds model will be a capit­u­la­tion in all but name to the Endoge­nous Money camp (Nick Rowe, 2013). Assum­ing that this is what Krug­man will attempt, I want to con­sider the empir­i­cal evi­dence on the rel­e­vance of pri­vate debt to macro­eco­nom­ics. If it is indeed true that pri­vate debt only mat­tered post-1985, then this is com­pat­i­ble with a secular-stagnation-augmented Loan­able Funds model – what­ever that may turn out to be. But if pri­vate debt mat­ters before 1985, when sec­u­lar stag­na­tion was clearly not an issue, then this points in the direc­tion of Endoge­nous Money being the empir­i­cally cor­rect model.

I will con­sider two indi­ca­tors: the cor­re­la­tion between change in aggre­gate pri­vate non­fi­nan­cial sec­tor debt and unem­ploy­ment, and the cor­re­la­tion between the accel­er­a­tion of aggre­gate pri­vate non­fi­nan­cial sec­tor debt and the change in unem­ploy­ment. I am also using two much longer time series for debt and unem­ploy­ment. Fig­ure 4 extends Krugman’s FRED chart by includ­ing busi­ness sec­tor debt as well (click here to see how this data was com­piled – and a longer term esti­mate for US debt that extends back to 1834: the data is down­load­able from here). The unem­ploy­ment data shown in Fig­ure 5 is com­piled from BLS and NBER sta­tis­tics and Lebergott’s esti­mates (Stan­ley Leber­gott, 1986, 1954, Christina Romer, 1986) and extends back to 1890.

Fig­ure 4: Long term series on Amer­i­can pri­vate debt

Fig­ure 5: Cor­re­la­tion of change in aggre­gate pri­vate debt with unemployment

Cor­re­la­tion is not cau­sa­tion as the cliché goes, but a cor­re­la­tion coef­fi­cient of –0.57 over almost 125 years implies that the change in debt has macro­eco­nomic sig­nif­i­cance at all times – and not just dur­ing either sec­u­lar stag­na­tion or liq­uid­ity traps.

Table 2:

1990 2000 –0.95 –0.95
2000 2013 –0.97 –0.95

Shorter time spans empha­size the point that nei­ther sec­u­lar stag­na­tion nor liq­uid­ity traps can be invoked to explain why changes in the level of pri­vate debt have macro­eco­nomic sig­nif­i­cance. Sec­u­lar stag­na­tion surely didn’t apply between 1890 and 1930, yet the cor­re­la­tion is-0.6; nei­ther sec­u­lar stag­na­tion nor a liq­uid­ity trap applied in the period from 1950 till 1970, yet the cor­re­la­tion is sub­stan­tial in those years as well.

The cor­re­la­tion clearly jumps dra­mat­i­cally in the period after the Stock Mar­ket Crash of 1987, but that is more com­fort­ably con­sis­tent with the basic Endoge­nous Money case that I have been mak­ing – that new pri­vate debt cre­ated by the bank­ing sec­tor adds to aggre­gate demand – than it will be with any secular-stagnation-augmented Loan­able Funds model.

The debt accel­er­a­tion data (Michael Biggs and Thomas Mayer, 2010, Michael Biggs et al., 2010) ham­mers this point even fur­ther. Fig­ure 6 shows the accel­er­a­tion of aggre­gate pri­vate sec­tor debt and change in unem­ploy­ment from 1955 (three years after quar­terly data on debt first became avail­able) till now. The cor­re­la­tion between the two series is –0.69.

Fig­ure 6: Cor­re­la­tion of accel­er­a­tion in aggre­gate pri­vate debt with change in unemployment

As with the change in debt and unem­ploy­ment cor­re­la­tion, shorter time spans under­line the mes­sage that pri­vate debt mat­ters at all times. Though the cor­re­la­tion is strik­ingly higher since 1987 – a date I empha­size because I believe that Greenspan’s actions in res­cu­ing that bub­ble then led to the Ponzi econ­omy that Amer­ica has since become – it is high through­out, includ­ing in times when nei­ther “sec­u­lar stag­na­tion” nor a “liq­uid­ity trap” can be invoked.

I await the IS-LM or New Key­ne­sian DSGE model that Krug­man will pre­sum­ably pro­duce to pro­vide an expla­na­tion for the per­sis­tence of the cri­sis in terms that, how­ever tor­tured, emanate from con­ven­tional eco­nomic logic in which banks and money are ignored (though pri­vate debt is finally con­sid­ered), and in which every­thing hap­pens in equi­lib­rium. But how­ever clever it might be, it will not be con­sis­tent with the data.

About Steve Keen

I am a professional economist and a long time critic of conventional economic thought. As well as attacking mainstream thought in Debunking Economics, I am also developing an alternative dynamic approach to economic modelling. The key issue I am tackling here is the prospect for a debt-deflation on the back of the enormous debts accumulated in Australia, and our very low rate of inflation.

    An obvi­ous prob­lem for both the Amer­i­can and our econ­omy is that they aren’t very effi­cient. Effi­ciency is an over used word but basi­cally an econ­omy should reward peo­ple for mak­ing good deci­sions. Instead every­one (except the poor, espe­cially in Amer­ica) has got their free hand­out. Poor tax sys­tem, sub­si­dies, eco­nomic manip­u­la­tion, exces­sively high wage rates in some areas, it all adds up.

    The whole prob­lem is that econ­o­mists are too busy defend­ing an impos­si­bly wrong the­ory or plod­dingly try­ing to craft another when all you really need to do is social­ize the money/financial sys­tems for indi­vid­u­als a la Social Credit/Citizen’s Div­i­dend which frees the indi­vid­ual, resolves the indi­vid­ual demand/debt prob­lem in per­pe­tu­ity and fits seam­lessly into a profit mak­ing eco­nomic sys­tem that now approx­i­mates an equi­lib­rium. Then all you have to do is tweak it with a peri­odic gen­eral dis­count on prices and reg­u­late obvi­ous eco­nomic excesses and we all actu­ally progress toward a future freed up to inno­vate and pro­vide for us all. Then we can get on with help­ing the small per­cent­age of peo­ple who will inevitably make Life mis­takes or have bad atti­tudes despite a gra­cious money sys­tem and an abun­dant economy.…wake up and die right. Life and Free­dom. It still per­son­ally has to be nav­i­gated by the indi­vid­ual, but it beats hell out of hav­ing to nav­i­gate it under the duress of an unsta­ble and rigged system.

    Hi Steve — still plug­ging away there and still a good read.

    Sec­u­lar stag­na­tion is an imper­fect term, but bet­ter than noth­ing I guess. What­ever it is, low pop­u­la­tion growth is a poor expla­na­tion for a lack of per capita GDP growth, and lack of inno­va­tion is not much better.

    My view is that the root cause is the cost of energy, since roughly the 1970s. Unless we get a nuclear rev­o­lu­tion or some other means of obtain­ing vast quan­ti­ties of energy at a lower price than coal, there is no relief in sight. Indeed, sec­u­lar stag­na­tion could become the Hun­dred Years Depres­sion, long before cli­mate change fin­ishes us off.

  7. Steve Hummel says:

    Social­ize the money sys­tem for the indi­vid­ual with a mid­dle class level guar­an­teed div­i­dend and the econ­omy will be in a vir­tual equi­lib­rium in no time. It’s too sim­ple for the aca­d­e­mic, too hor­ri­ble for the Banker to con­tem­plate and too hope­ful for the mass of indi­vid­u­als con­di­tioned to enslave­ment. But it’s gra­cious, and so res­o­nant with the indi­vid­ual if they think upon it for a while. And if for­mer eco­nomic aca­d­e­mics, who have already embraced an anal­o­gous con­cept like a debt jubilee, would muster the brav­ery to begin sug­gest­ing the uni­ver­sal div­i­dend as not just a res­cue but a solution.…they might some day be hailed as higher in the pan­theon than Smith or Marx…even if they had to set­tle for being the her­ald of Douglas.

  8. peteryogman says:

    Great arti­cle Steve. Bet­ter with­out the irony. Please expand on the hint that cor­re­la­tions are higher between debt and unem­ploy­ment after 1987 when the Ponzi econ­omy really became more dom­i­nant. I would think it would be a lower cor­re­la­tion since financ­ing the Ponzi econ­omy would not seem to be as labor friendly as financ­ing the real econ­omy unless its about employ­ment in the finan­cial sector.

  9. peteryogman says:

    Also the flawed pol­icy rec­om­men­da­tions of Krug­man et. al. based upon deeply flawed mod­els of the econ­omy are get­ting down­right scary — as if Greenspan didn’t do enough damage.

    Orig­i­nally posted to Mish Shedlock’s blog:

    Roth­bard Quote: “[Thus] we come to the star­tling truth that it doesn’t mat­ter what the sup­ply of money is. Any sup­ply will do as well as any other sup­ply. The free mar­ket will sim­ply adjust by chang­ing the pur­chas­ing power, or effec­tive­ness of the gold-unit [monetary-unit].”

    Me: Cor­rect. Except it is the Banks who cre­ate our money and “con­trol” the sys­tem. We play their game. If the money sup­ply was cre­ated and destroyed for the indi­vid­ual and grew or shrunk by his/her freely cho­sen decisions.…the indi­vid­u­als of the soci­ety, that is the real mar­ket makers…would be in control.…and busi­nesses and Banks would respond to those wants and needs as they should. What mat­ters is who is in actual con­trol the polis or the elite.

    Social Credit. The REAL lib­er­tar­ian, Aus­trian cap­i­tal­ism, not the dip­stick upside down, uncon­scious “mak­ing the world safe for inter­na­tional Bank­ing” Aus­tri­an­ism. Human Action, ha! Ironies abound.

    Boy, some of these econ­o­mists are lucky to have the aether, or print­ing press between us and them.

    We could teach them a thing or two.

    Now may be the appro­pri­ate time to repeat one of my favourite phrases. “Never put you wal­let in the care of an economist.”

    I can call very few econ­o­mists as my friend. Very few take my side.

  14. Bhaskara II says:

    If real US GDP has quadru­pled since 1965 and dou­bled since 1986 do we all have quadru­ple or dou­ble the real goods income since those times?

    Why not?

    I say income because GDP is a flow of “prod­uct” not level of wealth.

  15. Bhaskara II says:

    Where is this extra “real” GDP?

  16. Steve Hummel says:

    I say income because GDP is a flow of “prod­uct” not level of wealth.”

    Pre­cisely. GDP is not the cor­rect met­ric. Micro-economically it is indi­vid­ual mon­e­tary scarcity for the vast major­ity, and macro-economically it is a scarcity of total indi­vid­ual incomes in ratio to total costs/prices…simultaneously pro­duced. And let’s be hon­est, we live in a mon­e­tary econ­omy, not a barter one, that’s just DSGE dodge on the mat­ter. Money…matters.…economically. Social­iz­ing the money system…FOR THE INDIVIDUAL enables the next evo­lu­tion­ary step in profit mak­ing sys­tems because doing so still fits seam­lessly within a profit mak­ing eco­nomic system.…that ACTUALLY ade­quately pro­vides for and hon­ors the individual.

    Econ­o­mists need to look at the empir­i­cal evi­dence, always con­sider cost and what ACTUALLY occurs when money re-circulates, (scarcity of indi­vid­ual incomes in ratio to prices REMAINS) real­ize that this scarcity ratio accu­mu­lates through­out the entire pro­duc­tive process from raw mate­r­ial extrac­tion to pro­duc­tion to retail sale and that veloc­ity is the nom­i­nal amount of total mon­e­tary injec­tion by the Banks and to a lesser degree the government…BUT WHICH DOES NOT EQUATE WITH ACTUAL INDIVIDUAL PURCHASING POWER.

    Scarcity of indi­vid­ual income ele­men­tally and con­tin­u­ally is the real­ity. And the Aus­tri­ans are right…“there is no free lunch”.…UNTIL you look at the empir­i­cal data, observe the econ­omy accu­rately and then think lat­er­ally about solu­tions to the ele­men­tal reality…by adding a cost­less sup­ple­ment to indi­vid­u­als instead of merely pal­li­at­ing the prob­lem by inject­ing money into the sys­tem and re-initiating the ele­men­tal indi­vid­ual mon­e­tary scarcity.

    Indi­vid­ual mon­e­tary Grace as a mon­e­tary pol­icy is the solution.

    I am only an engi­neer so I have a rather dif­fer­ent per­spec­tive from all econ­o­mists. I agree with dyork — it is all about energy.

    US oil con­sump­tion per capita has been drop­ping for decades. Increased effi­ciency of energy use is not a seri­ous fac­tor as remote suburbs/Walmart are rel­a­tively recent developments.

    Instead of adjust­ing to real­ity, credit has been cre­ated to give peo­ple the delu­sion that their stan­dard of liv­ing is per­pet­u­ally increasing.

    As regards dyork’s com­ment on cli­mate, I beg to differ:

    Migrant,

    Total credit is not syn­ony­mous with total indi­vid­ual pur­chas­ing power.

    I’m inter­ested in eco­nomic equi­lib­rium, but nei­ther eco­nomic nor indi­vid­ual mon­e­tary equi­lib­rium can occur with­out a sup­ple­men­tary and direct dis­tri­b­u­tion of credit.…as a gift to the individual.

    If indi­vid­ual pur­chas­ing power is scarce then nom­i­nally and sys­tem­i­cally indi­vid­ual pur­chas­ing power speak­ing, -$5 +$5 = $0 addi­tional total credit…if there is a con­comi­tant reduc­tion in Bank­ing credit issuance/borrowing by indi­vid­u­als. Now if a mid­dle class lifestyle entails hav­ing $25/mo. then giv­ing every­one $25 or maybe even $30 will not only tend to be sat­is­fac­tory it will likely actu­ally result in a nom­i­nal decrease in bor­row­ing by the indi­vid­ual and employ­ment will sat­isfy the desire for more. Also, a peri­odic (monthly) gen­eral dis­count mech­a­nism based solely on total incomes spent over money/prices simul­ta­ne­ously pro­duced will main­tain a mon­e­tary and eco­nomic equi­lib­rium. Actively sta­bi­liz­ing an inher­ently unstable/extremely com­plex sys­tem with a math­e­mat­i­cally equat­ing mech­a­nism is called for…as opposed to merely BELIEVING in a godly con­cept like the market.

    Scarcity and poverty are asym­met­ri­cal with tech­no­log­i­cally abun­dant capa­bil­ity to pro­duce, and main­tain­ing eco­nomic and mon­e­tary equi­lib­rium while enabling inno­va­tion to progress will increase pro­duc­tiv­ity and even­tu­ally prob­a­bly even lower resource usage.…and at the very least enable the reduc­tion of many other costs. Both the present econ­omy and the money sys­tem are still godaw­fully inefficient.

    Hi Oct2009Migrant,

    I’m well aware that this is not a blog that talks about global warm­ing, but my pri­mate emo­tions get stirred when sci­ence is being attacked by ide­olo­gies. Global warm­ing was dis­cov­ered by cli­mate sci­ence, and no com­pe­tent cli­mate sci­en­tists will con­sider 17 years of data con­sti­tute a cli­mate (they are at best multi-year weather). I would like to urge you to go to http://www.skepticalscience.com/ for a more informed debate. You can then decide if the trend is warm­ing, and if it is, is it anthro­pogenic?

    Two points, firstly what is being ignored by the main­stream, sec­ondly that con­text (ris­ing demand or debt or falling demand or debt) is impor­tant.
    First point.
    Ok, let’s accept that there is sec­u­lar stag­na­tion as a work­ing hypoth­e­sis, but let’s agree that it is in the back­ground to the inher­ent insta­bil­ity of finan­cial cap­i­tal­ism, that is, how the bank­ing sys­tem works. The idea that the GFC is a one-off misses the point that the bank­ing sys­tem is unsta­ble and needs to be addressed. Sec­u­lar stag­na­tion is another issue, just like adapt­ing to cli­mate change and dif­fer­ing age demo­graph­ics in devel­oped economies that also need to be addressed.
    With regard to sec­u­lar stag­na­tion, the extent to which economies have ben­e­fited from under­pric­ing fos­sil fuels is a fac­tor which is under-appreciated. Appar­ent pro­duc­tiv­ity has been higher for longer, mean­ing that stag­na­tion has been over­looked for longer. As more cap­i­tal needs now to be put into find­ing oil and gas, prices have lev­elled at above $90 boe. In gen­eral, more cap­i­tal needs to be input for any pro­duc­tiv­ity gain. Apart from that, the emer­gence of China as “fac­tory of the world” has resulted in low­ered employ­a­bil­ity of less skilled work­ers else­where, plac­ing a drag on West­ern economies. This is a dou­ble whammy, less demand, less valu­able labour at the mar­gin.
    It should be appar­ent, but hasn’t sunk in, that all of the world’s mate­r­ial needs can be pro­vided by about 1/6 of all work­ing age per­sons. The rest is largely either dis­cre­tionary or gov­ern­ment ser­vices and a sig­nif­i­cant but unavoid­able group of ser­vices, such as med­ical. In a global econ­omy a gov­ern­ment led demand hit is likely to dis­si­pate quickly.
    Sec­ond point.
    I agree with Steve that Krug­man has a deal to explain as how increased debt increased demand when it should be neu­tral. What I think is wrong with (eco­nomic) the­ory in gen­eral is that equa­tions tell us noth­ing about cau­sa­tion. Con­sider E=MC^2. You can also write that as M=E/C^2. The first equa­tion tells you that a lot of energy is released in a par­tic­u­lar con­text, there is a cause going from LHS to RHS. The sec­ond equa­tional form tells you that mass is increased in a par­tic­u­lar con­text as you use energy to increase veloc­ity. The con­text is impor­tant, is each of demand or debt ris­ing or falling. Krug­man and Sum­mers should be asked to say that either the con­text does or does not make a difference.
