On private debt

By Steve Keen

I was highly critical of Paul Krugman’s recent academic paper on the financial crisis, because it argued, on neoclassical a priori grounds, that:

Ignoring the foreign component, or looking at the world as a whole, the overall level of debt makes no difference to aggregate net worth — one person’s liability is another person’s asset. (p. 3)

Given that criticism, I feel obliged to point out that in his recent comment on Rick Perry’s nomination for the Presidency, “The Texas Unmiracle”, Krugman makes a very sensible observation about the importance of “the overall level of debt” that contradicts the assumption he made in that paper. Observing that Texas’s allegedly better performance on employment growth is due mainly to “cheap labor”, Krugman comments that:

at a national level lower wages would almost certainly lead to fewer jobs — because they would leave working Americans even less able to cope with the overhang of debt left behind by the housing bubble, an overhang that is at the heart of our economic problem.

Bravo! The aggregate level of private debt does matter, and simplistic attempts to make businesses feel better by lowering their wage costs may actually reduce their revenue even more as already debt-depressed households see their disposable income above debt servicing and repayments shrink dramatically.

Here Krugman repeats the wisdom of Keynes on the same point during the Great Depression. Generally I regard Irving Fisher as superior to Keynes on the causes of the Great Depression, because he focused on the role of debt and deleveraging whereas Keynes, by and large, ignored it. However on one occasion—when considering the argument that neoclassical economists were making that the Depression could be ended by a cut in wages, Keynes made the following comment:

“Since a special reduction of money-wages is always advantageous to an individual entrepreneur … a general reduction … may break through a vicious circle of unduly pessimistic estimates of the marginal efficiency of capital…

On the other hand, the depressing influence on entrepreneurs of their greater burden of debt may partially offset any cheerful reactions from the reductions of wages. Indeed if the fall of wages and prices goes far, the embarrassment of those entrepreneurs who are heavily indebted may soon reach the point of insolvency–with severe adverse effects on investment.” (Keynes 1936, p. 264)

This points out the fallacy in neoclassical thinking that blames unemployment on wages being too high: since neoclassical theory ignores the role of debt, it imagines that dropping the price of labor will increase demand for it, by improving the profitability of firms. However as both Keynes and Krugman note, since private debt both exists and matters, cutting wages while leaving the level of debt unaltered can actually end up reducing demand by more than the fall in wages—leaving employer worse off than before.

Keynes also argued that a cut in money wages would also cause a fall in the price level, which would also increase the debt burden—though his statement of this was very convoluted, as was often the case when what he wrote challenged conventional theory:

“The method of increasing the quantity of money in terms of wage-units by decreasing the wage-unit increases proportionately the burden of debt; whereas the method of producing the same result by increasing the quantity of money whilst leaving the wage-unit unchanged has the opposite effect. Having regard to the excessive burden of many types of debt, it can only be an inexperienced person who would prefer the former.” (1936: pp. 268-69)

(“An inexperienced person” was Keynes’s satirical code for “a neoclassical economist”)

In English, Keynes is saying that cutting money wages will reduce the price level, which will increase the real debt burden. This is precisely what happened during the early years of the Great Depression. Here Fisher is the one to read rather than Keynes: his 9-step process of debt deflation began with:

(1) Debt liquidation leads to distress selling… (Fisher 1933, p. 342)

Which caused:

(3) A fall in the level of prices

Leading to the paradox that:

“the more debtors pay, the more they owe. (Fisher 1933, p. 344)

This is precisely what happened in the early, seriously deflationary stage of the Great Depression: businesses cut prices in an attempt to stimulate demand for their products, and paid their debt down with the proceeds, only to find that their real debt burden rose because the fall in revenue more than outweighed the reduction in debt.

I normally present just the ratio of debt to GDP when talking about how excessive debt causes economic crises:

Figure 1: US Private Debt to GDP

US Private Debt

But the really important story of the Great Depression is, as Fisher notes, is that the debt ratio rose even though the absolute level of debt was falling:

Figure 2: Rising Private Debt Ratio with Falling Debt

Rising private debt with falling debt

The same paradox applies when considering what might happen if wages are cut: by cutting wages without reducing the level of nominal debt, the debt burden will rise in real terms. It also leads to a paradoxical idea: the best way to reduce the debt burden might not be “printing money”—which Keynes in effect recommended in that second quote, and which Bernanke has in fact been trying—but raising money wages.

This wouldn’t increase real wages—because employers would pass on the cost increase—but it would very directly cause inflation, and thus reduce the real burden of debt.

Of course, there’s zero chance of that policy being tried, for at least two reasons. Decentralized wage setting means that there is no mechanism to do it in the first place, while both neoclassical economists and conventional pundits vehemently oppose wage rises anyway.

Here they’re being a bit like amateur drivers who find themselves in a spin because they’ve driven too fast around a bend. Their response is to turn into the bend even more—which results in the car spinning even more out of control. Expert drivers (and I’m not one, I hasten to add!) know that in that circumstance they have to do the counter-intuitive thing of turning the wheel in the opposite direction.

The bend we’re in is the process of debt-deleveraging, which as Richard Koo argues, turns conventional economic thinking on its head. But the way we’re going, we’ll behave like amateur drivers in a spin and make a bad situation worse by lowering wages during a debt-deflation.

Finally, one reason why deflation hasn’t been as sharp this time as it was in the Great Depression—even though the private debt level is higher—is that non-financial businesses are actually in less debt now than they were then. Non-financial businesses entered the Great Depression with a debt to GDP ratio of 100 per cent—well above the 75 per cent level that applied at the start of our crisis. So they don’t face the same direct pressure to service debts that led to the “distress selling” Fisher focused upon.

But households are in far worse shape now than in the 1930s, with a peak debt level that is two and a half times as high as it was in 1930. That’s why the crisis now is manifesting itself in stagnant consumer demand. It doesn’t involve the same plunge into deflation as the Great Depression, but it does imply a more drawn out deleveraging, because it’s much harder for households to reduce debt than it is for businesses. Businesses can get out of debt by going bankrupt, sacking workers, and stopping investment. Households have to live with the shame of bankruptcy and the limitations it imposes on behaviour in future, they can’t sack the kids, and it’s impossible to stop consuming completely. So we may face a far more drawn out process of deleveraging than the Great Depression.

To return to Krugman’s point, this is the last environment in which reducing wages makes any sense, however much appeal it might appear to have on a simplistic analysis.

    Great chart, etc. Consider how much further household deleveraging needs to go and how long it’s going to take. Look at the savings rate stuck at 5.1%. Once we get to savings rates experienced in early 80’s I’ll consider households adequately deleveraged. Something tells me it’s going to take a decade.

  2. Richard Rosso says

    Thanks edward!!!!!!

  3. Don Davis says

    The juxtaposition is between private and public debt. Private debt includes both businesses and households. I believe business have the greater debt by a considerable margin. Fisher’s paper is available at the St. Louis Fed’s site and is well worth a read – at about 40 pages.

  4. David Lazarus says

    HIgher interest rates would accelerate the de-leveraging process. It would also boost incomes for retirees. It would accelerate the fall in asset values and clear those debts.

    Longer term governments everywhere need to have caps on debts so that the economy does not get so inflated with debt and drive up asset prices. Though this would require governments to protect its constituents from its banks and their lobbyists. Banks will lobby against such restraints. Even though they will say that they know their customers best. Risk based models that the banks used to price such debts clearly did not work and in my opinion shows that the Basel risk capital rules are obsolete.

    The problem for consumers is that as their government has been bought by corporations any solutions that will help them will not get past a congress owned by corporations. So that means the US really is facing multi decade stagnation, even longer if balance budgets become law.

    I think the problem with the argument “one person’s liability is another person’s asset” is that it doesn’t take default into account.

    High debt levels increase the probability of default. If the debt isn’t collateralized or is collateralized on a deflated asset, and that debt is then defaulted on, then it’s nobody’s asset. That wealth just evaporated.

    1. David Lazarus says

      It also ignores sustainability. High debt levels can be unsustainable, especially if incomes fall. If it is on collateralised debts the original lending institution suffers no losses. It does encourage reckless lending.

  6. Warren Mosler says

    Seems federal deficit spending has worked to bring financial burdens ratios way down?

    1. David Lazarus says

      Primarily for business, but not so much for households.

  7. Element says

    Hi Steve,

    Heard you and Edward on ABC “Rear Vision” yesterday morning. As I was listening to both of you I was struck by two things;

    1. Steve thinks no one at IMF or FED saw the debt collapse coming.

    This I think is very wrong, for many reasons, that should be obvious.

    2. Edward still posits a formulae for the resolution and recovery of this mess.

    To which all I could think was, “ok, so who’s left to pay the debt then, and supply the waves of demand?”

    1. David Lazarus says

      The few economists who did see this coming were not interest only in flows of debts but balances. As for who will pay the debt? Much of that debt is unsustainable and will have to be written off. That will mean big losses for investors and banks. It could mean the end of the securitised business model.

      The current solution of inflating asset values so that people do not walk away from the debts means that they are trapped in debt servitude so any disposable income is paying creditors. Once these debts are written off the consumer will be in a much better financial position to spend supplying the demand needed.

    I have been reading Keen for a while, and I think what he says makes a lot of sense.

    When I hear that phrase that one person’s debt is another person’s asset, it just puts my teeth on edge. It strikes me as equivalent to an economist saying that slavery is just a shift in consumption and production between worker (slave) and owner, and as the sum total of production and consumption remains the same it is not a problem…

    1. Dimm says

      Great analogy!
