What Is Inflation?


“According to central bankers, inflation is generated by the gap between demand for goods and services and the economy’s ability to supply them.” This is a direct quote from an article that recently appeared in the WSJ, in which central bankers were described at being puzzled over the low rate of inflation that the G-20 has been experiencing. Inflation is a term which has taken on different meanings over time, and which continues to lead to general confusion.



The original meaning of the term was intended to reflect the central bank’s expansion, or inflation, of the money supply. Of course, generally, there is a relation between increased money supply and the price of things, with prices naturally rising for things that are measured in terms of another whose supply has just increased.  In time, the term “inflation became defined as being the secondary effect - rising prices, and not the primary cause – inflated money supply.

However, economic thinkers have over time made connections that are not necessarily always valid. To re-state: inflation is intended to refer to the expansion of money supply, and rising prices are a by-product of inflation, but not inflation itself. A common misunderstanding surrounding inflation is the belief that economic vibrancy leads to inflation. The thinking goes like this: cheap and abundant debt is made available which causes people to borrow and spend, which leads to an increased demand for goods, which causes companies to increase their hiring to produce more goods, which causes the unemployment rate to decline, which places the worker in an advantaged negotiating position which leads to increased wages, with those increased wages leading to more spending, and thus the cycle of rising prices and rising wages goes on. This is the current conventional view of inflation, and is at the root of the confusion at the Fed and other economic think-tanks, as they cannot seem to understand how with the unemployment rate so low today, the cycle of inflation that they defined, know, and love has not happened.

They forget the lesson of pre-WWII Germany, or if you prefer more recent examples the lesson of modern-day Venezuela. In both instances, the economies were in shambles, with very high unemployment rates and no consumer spending power. And yet in both instances, the value of the respective currencies collapsed completely and prices for things as measured in those currencies soared. From these examples, we learn that inflation, and the concurrent devaluation of currencies and soaring prices of things, need not be prompted by a healthy and vibrant economy with strong employment. Money printing in sufficient amounts will do the trick just fine.

We also have come to confuse inflation with necessarily being accompanied by very high levels of interest rates. This is the so because the greatest bout of inflation in modern U.S. history occurred in the decade beginning 1972, and during this time prices and interest rates, both soared. And in the conventional view where a vibrant economy characterized by low unemployment and higher spending leads to inflation, this would be true. But in today’s world, where central bankers have intervened very heavily in the interest rate markets, surely out of a perceived necessity given global debt levels, there is and will continue to be a decoupling of interest rates and inflation.

Taxes and Hyperbole

There is a new tax code in the U.S., and this is indeed a “Yuuuge” deal. As far as I can tell, it is as close to an unmitigated home run for America as can be. Is it perfect? Of course, it’s not. The code retains its unwieldy size and complexity, largely as a result of compromises made in order to bribe congressmen and senators for their votes. Until we get term limits, it seems we’re stuck with a tax code that is big and complex. However, it does hit the mark on a few key issues: most every taxpayer will now pay less to the federal government (except those in states with ridiculously mismanaged economies who now will be forced to hold their state politicians more accountable); and our businesses, large and small alike, will remit less of their profits to the federal government and will be liberated to invest that savings into growth – which will surely create job and wage growth in the productive private sector.

You Need to Ask the Right Question

If you ask the wrong questions, the answers will probably also always be wrong, and even irrelevant.  This might seem obvious, but I’ve noticed that this truth is often completely overlooked, and even by the world’s most intelligent. While I’m certain this is so in every facet of life, for the purpose of this short paper I will focus on the investment/finance world.

Interest Rates & The Trade War

These are the twin bogeymen that the hysterical media will continue to lean on to drive fear into the hearts of men and women and keep them glued to their TV sets for the predictable backwards looking drivel. Here is a different perspective for you to chew on:

Interest rates cannot go up by too much. Our nation has to service more than $20T of national debt and must also maintain a massive social safety net that will increase that debt by a further 50% before Trump’s second term ends. All the rest of the analysis is unimportant.
