What is Inflation: Five Types of Inflation Defined


Over on RealMoney, Barry Ritholtz argues that the U.S. government is probably underestimating inflation because it is focusing on the wrong type of inflation. I would agree with that, having identified no less than five different types of inflation: commodity inflation, wage inflation, monetary inflation, fiscal inflation, and foreign exchange inflation. Before discussing “inflation,” it helps to define, “What is inflation” and identify which form of inflation is being talked about. Failure to do so may have caused some of the confusion that often surrounds this topic.

The inflation that most American economists remember best (from the 1960s and later) is wage inflation, otherwise known as demand-pull inflation. Workers observe rising prices and demand compensation in the form of higher wages, which creates a vicious cycle of more inflation and more wage demands. This has not been happening until recently in the United States, due to the absence of labor unions, and to what Karl Marx called the “reserve army of the unemployed” in “offshore” markets. This appears to be the form of inflation that the Fed and other U.S. government authorities are focusing on, and it has indeed been benign up to now.

A less common, but more volatile form of inflation is commodity inflation, better known as cost-push inflation. We can see it today in commodity prices such as energy and metals. Energy and food price changes are excluded from “core” inflation because of their period-to-period volatility. But over time, oil price rises have averaged 6% a year, higher than other forms of inflation, and assuming that they don’t cause inflation is really assuming away the problem. Other commodities such as timber rise at 3% a year “real” (above the rate of calculated inflation).

That’s largely because such rises are (wrongly) excluded from the calculation. Another form of commodity inflation that is excluded from the official statistics has been the parabolic rise in housing prices. (The government instead uses a calculation of “owner equivalent rents,” which are basically tied to the benign wage numbers.) Commodity inflation is the most obvious form of inflation today (after having been quiescent in the 1990s), as reflected in higher food, gasoline and gas bills, but is severely understated.

Monetary inflation was most famously seen in Weimar Germany during the 1920s, when the German government went crazy with the printing presses to the point where it took billions of marks to equal one dollar. This wiped out the savings of the middle class, most members of which were compensated with (worthless) “million mark” notes, and eventually led to the rise of Hitler. Nothing of this sort has happened in the western world since, but it is a worry when the United States has a chairman of the Federal Reserve who has talked (hopefully facetiously) of dropping money out of helicopters.

Fiscal inflation is due to excess government spending, for which the budget deficit is a reasonably good proxy. It originated in the “guns and butter” spending of President Lyndon Baines Johnson in the 1960s, and similar spending of today’s President George W. Bush. We have war spending without a “war economy” e.g. rationing or wage and price controls, and if the 1960s are any guide, we will be paying the price later this decade and in the 2010s.

The last type of inflation, foreign exchange inflation, is particularly scary to me, someone who lived in Mexico before and during the peso crisis in 1994. This happens when the local currency (pesos in this case) falls dramatically against other world currencies, thereby sharply raising the price of imported goods, and hence the overall price level.

This is a real worry for the United States when the latest annual trade deficit is somewhere over $760 billion. I’m not looking for anything like the two-thirds fall of the Mexican peso in 1994-95 as a result, but even a 20% across the board drop of the U.S. dollar against the Euro, yen and yuan (the Chinese currency was unpegged from the dollar only in 2005) would be a severe shock stateside.

Inflation, The Sixth Sense: Asset Inflation Financial assets inflation is what we’re observing all around the world at the moment. Information technology has enabled us to conquer drastic reductions in the costs of transacting financial assets, most notably stocks. With lower transaction costs, and consequent increase in traded volume (turnover in US equity markets has quadrupled since 1980), stocks have become an effective alternate to sovereign money as a means of exchange. We get paid in company stock; what could be a clearer sign? With higher liquidity, stocks trade at a lower discount. This means their prices go up. However,… Read more »

Monetary inflation is better advocated utilizing the equation of exchange and the quantity theory of money, the former, which is MV=PT (money supply x velocity of circulation = price levels x total transactions) and the latter, explains that the velocity of circulation be will equal to the level of transactions, therefore after removing them from the equation, only M=P remains, hence saying that any change in the money supply will bring about a change in the level of prices.

What is inflation by defination: inflation is persistent rising in price of commondities. If looks around the world todays inflation has caused alots of damages to our economy. If we are to examines the types of inflation that occur in 1960s around the world is not even caused damage to economy alone, but to well-being of nations affected. In ours’ nation today the rate of inflation had gone beyoung the normal standard of economic statistics. Independent of money(sovereignty of money) it means when money valuation-standard without been inflated.

(1) Creeping inflation: a period of gentle level continuous rise in the general price level of <5%/ year. (2) Hyper inflation: rapid rise the general price level causing serious instability in the economy. (3) Walking inflation: prise rise moderatly&annual inflation rate is a single digit of between 5-10%. (4) Running inflation: price rise at the rate of 10-20% (annualy). (5) Pure inflation: A situation in which all price inculding wages & order source of income rise at an equal rate. (6) Shock inflation: A sudden change in the price level that is caused by a rise of an important goods.

What I really need to know is what triggers inflation and what are the remedies that curve inflation.
Thank you

Inflation is man-made – a consequence of man’s agenda for profit and business interests. Inflation does not simply pop out of thin air. Man raises or lowers the price of his commodities or services to pursue his business direction ( popularly known as corporate goals). You may categorize inflation into such names as wage, monetary, commodities,foreign exchange, etc.. yet they are all one and the same. The common denominator is the Price, the rise and fall of which changes the value of the money in our pockets.Man himself and his lieutenants under a corporate mantel known as corporation or whatever… Read more »
