Gibson's paradox

Last updated

Gibson's paradox is the observation that the rate of interest and the general level of prices under the gold standard [1] are positively correlated. [2] It is named for British economist Alfred Herbert Gibson who noted the correlation in a 1923 article for Banker's Magazine. The correlation had been noted earlier by Thomas Tooke. [3]

The term was first used by John Maynard Keynes, in his 1930 work, A Treatise on Money . [4] It was believed to be a paradox because most economic theorists predicted that the correlation would be negative. Keynes commented that the observed correlation was "one of the most completely established empirical facts in the whole field of quantitative economics."

The Quantity Theory of Money predicts that a slower money-growth creates slower price-rise. In addition, slower money-growth means slower growth of loanable funds and thus raises interest rates. If both these premises are true, slower money-growth should mean lower prices and higher interest rates. However, Gibson observed that lower prices were accompanied by a drop—rather than a rise—in interest rates. This is the paradox that needs to be explained. For instance, in the 1873-96 depression, prices fell considerably while interest rates remained low. Economist S.B. Saul says that Alfred Marshall explained the paradox by saying that other factors might have been at play: a peace dividend and improving international system of banking and finance.

Economists generally thought that interest rates were correlated to the rate of inflation, whereas Keynes' findings contradicted this view. During the period of gold standard, he concluded that interest rates were correlated to the general price level, and not the rate of change in the prices. In fact, he thought that interest rates were highly correlated to the wholesale price index rather than the rate of inflation. [5]

With the establishment of the Federal Reserve in the United States in 1914, the correlation between interest rates and the general price level evaporated. This has led most commenters, including Barsky and Summers, to conclude that the correlation was a gold-standard phenomenon and that this can be observed in the inverse correlation between real gold prices and real interest rates.

Others have argued that this is not a strictly gold-standard phenomenon and continued in the correlation between real commodity prices and the earnings yield on equities. [6]

Keynesian economics are the various macroeconomic theories and models of how aggregate demand strongly influences economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the productive capacity of the economy. It is influenced by a host of factors that sometimes behave erratically and impact production, employment, and inflation.

<span class="mw-page-title-main">Macroeconomics</span> Study of an economy as a whole

Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study topics such as output/GDP and national income, unemployment, price indices and inflation, consumption, saving, investment, energy, international trade, and international finance.

Stagflation refers to an economic condition characterized by a simultaneous occurrence of high inflation, stagnant economic growth, and elevated unemployment. This phenomenon challenges traditional economic theories, which previously suggested that inflation and unemployment were inversely related, as depicted by the Phillips Curve. The term stagflation, a blend of "stagnation" and "inflation," was popularized by British politician Iain Macleod in the 1960s, during a period of economic distress in the United Kingdom. It gained broader recognition in the 1970s following a series of global economic shocks, particularly the 1973 oil crisis, which significantly disrupted supply chains and contributed to rising prices and slowing growth.

<span class="mw-page-title-main">Gold standard</span> Monetary system based on the value of gold

A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold, effectively ending the Bretton Woods system. Many states nonetheless hold substantial gold reserves.

<span class="mw-page-title-main">Inflation</span> Devaluation of currency over a period of time

In economics, inflation is a general increase in the prices of goods and services in an economy. This is usually measured using a consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices faced by households do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose.

<span class="mw-page-title-main">Monetarism</span> School of thought in monetary economics

Monetarism is a school of thought in monetary economics that emphasizes the role of policy-makers in controlling the amount of money in circulation. It gained prominence in the 1970s but was mostly abandoned as a direct guidance to monetary policy during the following decade because of the rise of inflation targeting through movements of the official interest rate.

In economics, deflation is a decrease in the general price level of goods and services. Deflation occurs when the inflation rate falls below 0%. Inflation reduces the value of currency over time, but deflation increases it. This allows more goods and services to be bought than before with the same amount of currency. Deflation is distinct from disinflation, a slowdown in the inflation rate; i.e., when inflation declines to a lower rate but is still positive.

Full employment is an economic situation in which there is no cyclical or deficient-demand unemployment. Full employment does not entail the disappearance of all unemployment, as other kinds of unemployment, namely structural and frictional, may remain. Full employment does not entail 100% employment-to-population ratio. For instance, workers who are "between jobs" for short periods of time as they search for better employment are not counted against full employment, as such unemployment is frictional rather than cyclical. An economy with full employment might also have unemployment or underemployment where part-time workers cannot find jobs appropriate to their skill level, as such unemployment is considered structural rather than cyclical. Full employment marks the point past which expansionary fiscal and/or monetary policy cannot reduce unemployment any further without causing inflation.

The Phillips curve is an economic model, named after Bill Phillips, that correlates reduced unemployment with increasing wages in an economy. While Phillips did not directly link employment and inflation, this was a trivial deduction from his statistical findings. Paul Samuelson and Robert Solow made the connection explicit and subsequently Milton Friedman and Edmund Phelps put the theoretical structure in place.

Within the budgetary process, deficit spending is the amount by which spending exceeds revenue over a particular period of time, also called simply deficit, or budget deficit, the opposite of budget surplus. The term may be applied to the budget of a government, private company, or individual. A central point of controversy in economics, government deficit spending was first identified as a necessary economic tool by John Maynard Keynes in the wake of the Great Depression.

The causes of the Great Depression in the early 20th century in the United States have been extensively discussed by economists and remain a matter of active debate. They are part of the larger debate about economic crises and recessions. The specific economic events that took place during the Great Depression are well established.

The quantity theory of money is a hypothesis within monetary economics which states that the general price level of goods and services is directly proportional to the amount of money in circulation, and that the causality runs from money to prices. This implies that the theory potentially explains inflation. It originated in the 16th century and has been proclaimed the oldest surviving theory in economics.

The paradox of thrift is a paradox of economics. The paradox states that an increase in autonomous saving leads to a decrease in aggregate demand and thus a decrease in gross output which will in turn lower total saving. The paradox is, narrowly speaking, that total saving may fall because of individuals' attempts to increase their saving, and, broadly speaking, that increase in saving may be harmful to an economy. The paradox of thrift is an example of the fallacy of composition, the idea that what is true of the parts must always be true of the whole. The narrow claim transparently contradicts the fallacy, and the broad one does so by implication, because while individual thrift is generally averred to be good for the individual, the paradox of thrift holds that collective thrift may be bad for the economy.

Asset price inflation is the economic phenomenon whereby the price of assets rise and become inflated. A common reason for higher asset prices is low interest rates. When interest rates are low, investors and savers cannot make easy returns using low-risk methods such as government bonds or savings accounts. To still get a return on their money, investors instead have to buy up other assets such as stocks and real estate, thereby bidding up the price and creating asset price inflation.

<span class="mw-page-title-main">History of macroeconomic thought</span>

Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.

The Cambridge equation formally represents the Cambridge cash-balance theory, an alternative approach to the classical quantity theory of money. Both quantity theories, Cambridge and classical, attempt to express a relationship among the amount of goods produced, the price level, amounts of money, and how money moves. The Cambridge equation focuses on money demand instead of money supply. The theories also differ in explaining the movement of money: In the classical version, associated with Irving Fisher, money moves at a fixed rate and serves only as a medium of exchange while in the Cambridge approach money acts as a store of value and its movement depends on the desirability of holding cash.

Inflationism is a heterodox economic, fiscal, or monetary policy, that predicts that a substantial level of inflation is harmless, desirable or even advantageous. Similarly, inflationist economists advocate for an inflationist policy.
