Understanding our Economic Trajectory – 1952 to Today

This is a guest post by “Shunyata.” Shunyata has training in financial engineering, actuarial science, statistics, and mechanical engineering. While he does not work directly with structural economic theory, his background in financial engineering gives him insights. The observations below represent Shunyata’s personal opinions based on his study of economics and monetary policy to protect his personal interests. This post is not intended to represent investment advice.

Since 1952, Nominal GDP has grown by about 6% per year. Why did this growth occur?

A. Did the economy discover new efficiencies and/or develop new natural resources?

B. Did Government monetary policy artificially inflate GDP?

C. Did Society borrow against tomorrow to purchase luxuries today? (…meaning that Society borrowed against tomorrow’s GDP to inflate today’s growth.)

Certainly reality is a mixture of all three mechanisms, but is one dominant? We would hope for (A). We can live with (B). But (C) would be troubling.

We can evaluate the impact of monetary policy by examining Real GDP trends. Figure 1 shows Gross GDP divided by CPI to bring everything to 2011 levels.

NOTE: Throughout most of this analysis, only data up to the 2008 crisis is presented. The reason for this is that since 2008 non-debt policy tools such as government guarantees, government equity positions in private companies, and Quantitative Easing are used in large scale – a very different paradigm than previous years. So data up to the 2008 crisis is used to build insight about the mechanisms affecting economic growth and evaluate our current economic policies.

In Figure 1 we can see that Real GDP has been growing at about 2.8% per year. Although about half of GDP growth has been nothing more than inflation, there clearly has been genuine growth in the productive economy.

But not all is rosy. Looking at this sequence on a log-plot, however, we can see that this rate has SLOWED over time from about 3.5% down to 2.5%:

Clearly, something fundamentally changed in the economy beginning around 1980. There are three obvious candidates for this change.

  1. During the ‘70s and early ‘80s, inflation was quite high which dampens Real GDP.
  2. Since the mid ‘80s, annual debt growth has been at about half the rate incurred during ‘70s, which dampens real economic expansion.
  3. Energy and raw material availability/price has increasingly become a constraint on real growth.

We can further evaluate the impact of borrowing on GDP by examining the relationship between Debt and GDP. Here is the one-year change Nominal GDP compared to the one-year change in US Total Debt. These points represent overlapping quarterly intervals since 1952.

Here we see a very strong linkage between Debt and GDP. A few features are very important:

  1. Debt growth around 5% has no impact on GDP. This result suggests that GDP income alone is insufficient to service our societal obligations. This result suggests that we have to borrow 5% per year just to maintain our current lifestyle. This result should be troubling.
  2. Debt growth above 10% has no incremental benefit to GDP (possibly even a negative benefit). This result should raise serious questions about current fiscal policy.
  3. 5%-10% borrowing only creates 4%-8% GDP in the short-term. The longer-term benefit may be more significant.

Debt isn’t necessarily a bad thing – if it is “investment” in permanent productive capacity that will permanently raise GDP. Think about using debt to build a steel mill that supplies high quality material to the economy for decades to come. But if debt is used to purchase “ephemeral” goods like vacations or lawn service there is no return on the debt and you have created a future drag on the economy.

In a non-equilibrium economy is it not easily answerable whether an economy’s borrowing is “investment” or “ephemeral” in net. When money is borrowed today to make capital investments in the economy, the returns are realized over time. In a rapidly expanding economy, GDP growth will lag debt growth but eventually GDP will catch up and grow to a permanently higher level.

If debt is not used for “investment” or if growth occurs too quickly, however, debt can accrue to unsustainable levels resulting in default and lower economic activity. Since 1952, Total Public, Corporate and Private Debt has grown by about 8% per year while Nominal GDP has grown at about 6% per year. We can see this disparity in the Debt-to-GDP Ratio.

borrowing at a faster rate

Figure 4. (Note from Gail--this is the sum of "Governmental Debt" (Figure 3) and "Non-Governmental Debt" (Figure 1), in my 65-year Debt Bubble post. http://ourfiniteworld.com/2011/10/10/the-united-states-65-year-debt-bubble/)

Even if all of this borrowing is “investment”, it is clearly occurring at a rate faster than we are accruing the benefits of that investment. At some point, the debt service will exceed our short-term ability to pay it, even if all of the investments we made were sound in the long-run. Evidence all around us suggests that we have reached that point. Individuals are defaulting on personal debt. States and municipalities are defaulting on public debt. Nations are defaulting on sovereign debt. Financial Institutions have only escaped default by borrowing from tax-payers. Corporations have escaped default by cutting expenses and relaxing accounting standards – neither of which is a permanent solution.

From this viewpoint, our economic situation cannot possibly be corrected with MORE borrowing. Fortunately, we are not borrowing more.

Despite record expansion of Government debt, total debt in the economy has not increased since 2008! But unfortunately, until we pay down the debt burden (or default) that got us in this trouble we have not escaped or corrected the problem. What we have done, however, is:

  1. Relaxed accounting rules to allow corporations to inflate the reported value of assets and reduce the reported value of liabilities. This tactic obscures the true financial health of corporations, focuses attention on current earnings rather than long-term viability, and preserves poorly managed companies in expectation of a better tomorrow.
  2. We have shifted who is responsible for paying debts from financial institutions to private individuals. As large corporations, insurance companies, investment banks and savings institutions have found themselves unable to fully back their obligations, the Government has provided bailout funds, taken equity positions and issued guarantees – ultimately making the taxpayer responsible for these obligations. But this solution is no more sustainable than the original problem, either financially or socially.

What comes next will eventually be a debt contraction. Since we are fundamentally unable to even pay interest on the current debt, let alone pay it down, the contraction will eventually come through default. When this default happens, large swaths of “assets” will suddenly be worthless. This default will directly impact financial assets like pension plans, insurance contracts, and investment accounts. And this reduction in wealth will spill over into reduced demand for goods and services (including labor) throughout the entire economy. Prices for all goods and services will fall or cease to be available – this is deflation.

Central Banks are trying to avert this outcome by engaging in Quantitative Easing to indirectly pump money into the economy, avoid direct defaults, and stabilize the value of financial assets. Here is the one-year change in S&P500 Log Returns compared to the one-year change in US Total Debt. These points represent overlapping quarterly intervals since 2000.

Here we see what mechanism the Central Banks are trying to leverage – pumping money into the markets very effectively drives equity returns (either through inflation or by increasing GDP).

More recently, this has been accomplished through Quantitative Easing rather than direct debt issuance. Some reasons for this approach are that it is quicker to flow into the economy and allows economic planners finer control over the outcome. But another consideration is likely recognition that the economy cannot easily absorb greater debt levels.

One consequence of Quantitative Easing is devaluation of debt, both for the note holder and the debtor, by fueling inflation in the broad economy, especially in liquid financial instruments. (And the parallel consequence of deflation is inflated valuation of debt, both for the note holder and the debtor, an outcome economic planners are deliberately trying to avoid.) This Quantitative Easing / inflation approach can help if the Average Citizen holds financial assets and can reap the benefits of this “liquidity infusion”. But the wealth concentration in the developed world precludes this escape. The Average Citizen does not have a pension, does not have meaningful savings. Central Bank actions benefit those few who need it least and extract a terrible unemployment and inflated cost-of-living penalty on the rest. And this reduction in wealth will spill over into reduced demand for goods and services (including labor)throughout the entire economy, reduced tax base, and debt service default. Again,prices for all goods and services will fall or cease to be available – this too is deflation.

So how do we summarize our current economic health?

  1. Almost half of our “growth” has been monetary inflation.
  2. Our real growth has been heavily funded by debt accumulated at an unsustainable rate.
  3. Our debt is at a level that is not serviceable. Inflation and resource availability (especially energy) further reduce the serviceable level of debt.
  4. Our debt level has not been materially reduced since the crisis began.
  5. Our policy response has been to fuel inflation. This course will ultimately adversely impact resource affordability and further reduce the serviceable level of debt.
  6. Debt level and economic activity will ultimately be reduced.

Both financial and physical factors suggest that we cannot enjoy a resumption of Business As Usual. Credit availability must contract to sustainable levels and natural resource availability is unlikely to materially expand. Together these factors have a profound impact on societal features we have taken for granted. Imagine a return to cash-based transactions rather than credit. In a zero-growth economy, what happens to investment portfolios, pensions, social insurance, and public works? Without readily available credit or energy, business models such as “mobile warehousing”, disposable goods, and e- tailing may no longer be viable. Managing these transitions requires prudent rethinking of our expectations, physical lifestyles, and financial positioning.
