What are you smoking? The macro-economists supreme weakness: flows vs. balance sheets

In 2008, the financial sector was on the brick of collapse. Even if it accounted for only 4% to 10% of GDP (depending on the country), you could not let it implode. It's not the size of a sector itself that is relevant for assessing its economic importance. It is its connectivity with the rest of the economy. And no other sector is more at the centre of the economic system in a market economy than the financial sector. A feature it arguably shares with the electricity grid. So unless you think that because the electricity industry only accounts for 2% of GDP you can let the electricity grid collapse without causing a devastating damage on the rest of the economy, you cannot let the financial sector implode either (that instead of rescuing it via bail-outs you should rather do it via bail-ins is another story). This is the point that Larry Summers very correctly made at the latest IMF conference (8 November 2013). So far, so good.

But then he goes further and argues that monetary policy became ineffective in the developed world ("liquidity trap") because the equilibrium real interest rate is actually negative! Meaning: the FED, BoE, ECB & Co should keep their ultra-loose monetary policy for many years to come and try to create asset bubbles as without them there isn't any hope for economic growth to take place. On top of it, governments of developed countries should run large deficits and launch a massive programme of public investment financed by central banks monies for many, many years.

Paul Krugman, even goes further. He argues that it would be desirable for the private corporate sector to invest in all kinds of projects, even when their rates of return were likely to be negative at inception (and way, way below their cost of capital), because it would generate employment.

Negative real interest rates as the ideal asset allocation mechanism in a market economy? Asset bubbles as a way to generate sustainable economic growth? The government as a better investor and resource allocator than the private sector? Private companies pursuing projects with negative rates of return to generate demand and employment in the short-run and forgetting the mid-term consequences of it, i.e., sound companies today going bankrupt tomorrow as a result of bad investment decisions and....well...creating unemployment?

Larry Summers' and Paul Krugman were some of my heroes as I was an economics student. What happened? What are you smoking, guys?

To be fair, I don't think that they are smoking anything that they were not smoking years ago. But we all are the product of our education, training and experiences. Paul Krugman and Larry Summers included. And they happen to be academic (macro-)economists by education and training. Their views are simply the result and perfect example of macro-economists' supreme weakness: excellent at analyzing flows, terrible understanding balance sheets.

The reason why US and European monetary policies are ineffective is because the economies are over-leveraged. Balance sheets are impaired across the whole economy. When that happens no matter how low interest rates are, no one is neither willing nor able to take on more debt. The absolute priority is to de-leverage. Banks are impaired (even if they say otherwise) as a high percentage of the credits they conceded are de facto non-performing loans as a result of having been used to finance projects that turned out to have negative rates of return - why else would the borrowers not have been able to pay them back and in fact had to increase their levels of debt over time?

In such a scenario, a debt restructuring across the board is the only quick and effective solution. Followed by a recapitalization of the banking sector via-debt-to-equity swaps (bail-ins). Once this is done, all the problems are solved and monetary policy becomes effective again. Interest rates will start functioning, again, as the signaling mechanism for financial resource allocation across the economy they are supposed to be. Or would anyone not borrow money if he/she suddenly had no debts and lending rates were 2%?

Putting it differently: increasing leverage is a powerful economic growth accelerator until over-leverage is reached. When leverage turns into over-leverage is an interesting academic discussion for which there is no clear ex-ante answer. However, it is very easy to spot when that point is reached.....once it is reached: monetary policy becomes ineffective ("liquidity trap") and debt restructuring across the board is needed.

You don't solve the problem of an impaired balance sheet by trying to artificially increase the value of the assets - if a balance sheet is impaired that must mean that the quality of the assets is bad, i.e., they were not and are not able to generate sustainable positive returns. The result of bad investment decisions. You solve the problem of an impaired balance sheet by accepting that the assets are worth much less than they are accounted for and restructuring the balance sheet's right side, where equity and debt sit.

That public investment in areas where clear positive externalities exist, able to generate a positive impact on the economy's supply side (improvement of education system, internet / telecom infrastructure, transport infrastructure, R&D) and lead to an increase of potential GDP does make sense is undisputed. No one with a reasonable degree of common sense challenges that. But it has to be a complement to a comprehensive balance sheet restructuring in the private and public sector. Not a substitute for it.

PS Look at the Japanese total level of debt (both public and private) at the beginning of the 1950s and in 1989, when the country's two lost decades started. Do the same for the US and Europe: in both cases starting at the beginning of the 1950s up to 2007.

What do you see? A continuous increase in total debt as a % of GDP and since 1989 in Japan and 2007 in US / Europe a completely ineffective monetary policy in terms of generating economic growth. These were the points in time were over-leverage and impaired balance sheets finally revealed themselves.
