Deflation or Inflation - Guide to Picking Poisons

America's Greatest Fear - Deflation

Deflation is a decline in the price level of goods and services.  Generally, we cheer when the price of goods (groceries, gas, cars) decline.  As for policy makers, they fear deflation as if it was the great plague.  In fact, no country champions the cause against deflation more strongly than the U.S.

To understand the paradigm of America's decision makers, we must turn to a lesson in history.  The worst recession in recent memory, the Great Depression of the 1930's, was a deflationary period.  During such episodes, the economy could experience deflationary spirals, whereby declining prices induce the expectation of ever-lower prices in the future, hence creating a feedback-loop which results in uncontrolled price declines.

In addition, policy makers may run into what is known as a liquidity trap, whereby their traditional tools of monetary policy become exhausted.  This exact problem was addressed by current Fed Chairman Ben Bernanke, in the now famous speech Deflation: Making Sure "It" Doesn't Happen Here.  Chairman Bernanke reassured congress that through the 'helicopter drop' of money, the Fed would be able to successfully combat deflation.  With regard to this assertion, I am inclined to agree with Chairman Bernanke; I am also deeply concerned about the potential ramifications of such reckless monetary policy.  My fears are echoed by our neighbors across the Atlantic.


Germany's Worst Nightmare - Inflation

Just as America's paradigms were influenced by its history, so too were those of the German people.  Though the inflation in the Weimar Republic, post WWI Germany, was nearly 100 years ago, the people have not forgotten the horror:

Inflation is an increase in the general price level of goods and services.  Hyper-inflation is the runaway effects of such a price increase.  From the years 1918 to 1923, what used to cost 1 Mark increased in price, until the same good could not be purchased for less than 1 Trillion Marks.  To personalize this increase, imagine a 1 liter bottle of Coke costing approximately $1,000,000,000,000 dollars.  It sounds ridiculous, but sadly, it was a part of German history (Germans were not alone in this... hyperinflation dates back to as far as the time of the Romans... likely since the invention of money itself ).

All I'm saying is...

I believe our policy makers are influenced greatly by the events of the country's history.  To that extent, the strong aversion to deflationary periods is understandable.

However, the lack of respect for counterbalancing forces could force us to learn some harsh lessons in the near future.  Perhaps we should turn to our German neighbors to strike a more balanced view.

  1. yglesias had a good post today on why Germany's fear of inflation is based on bad history: http://yglesias.thinkprogress.org/2010/06/germanys-bad-folk-history/

  2. I think its too easy to point at one period in history, then point at another later point and say "cause/effect"...

    Unfortunately, what is easy is not always right. However, I will try to use this same simplicity to present a counter argument:

    Hyperinflation in latter-day-Rome crippled the emperial economy, and perhaps doomed the empire itself - this, in turn, led to hundreds (thousand?) years of dark ages...

    I'm inclined to believe, as many people that died directly/indirectly due to Hitler (and deflation), magnitudes more (at least in % of total world population), died due to the barbarism of the dark ages (and inflation)...

  3. Speaking of bad history...

    i think school systems do a terrible job of teaching history...

    they teach cause, effect, cause, effect... rinse/repeat (no offense to the educators, but shame on you administrators)

    history does not lend itself to such straightforward explanations. maybe that's why we never learn from it, and are forever doomed to repeat it.
