Economics chap 22 Flashcards
Economic growth and business cycles
Economic growth
Economic growth is traditionally defined as the annual rate of increase in total production or income in the economy
First, the production or income should be measured in real terms, that is, the effects of inflation should be eliminated. Second, the figures should also be adjusted for population growth
Positive economic growth
Positive economic growth actually occurs only when total real production or income is growing at a faster rate than the population. In practice, however, economic growth is usually simply measured by determining the annual growth in real production or income.
Some problems associated with GDP
GDP and the other national accounting totals all have certain shortcomings
(“grossly deceptive product” or the “grossly distorted picture”
Non-market production
It is difficult to measure or estimate the value of activities that are not sold in a
market. This problem applies, for example, to the production of goods and services by the government. It is assumed, for example, that the value of the output of a public servant is equal to his or her salary. Another example of non-market production is farmers’ consumption of their own produce
Unrecorded activity
many transactions or activities in the economy are never recorded. Such transactions or activities are described by terms such as the unrecorded economy, the underground economy, the shadow economy and the informal sector Unrecorded activities range from smuggling, drug trafficking and prostitution to cash transactions aimed at evading taxation(black market). The existence of such unrecorded activities may result in a serious underestimation of the value of GDP. As a result, GDP figures are nowadays adjusted by including estimates of the total value of unrecorded activity
Data revisions
the original estimates are frequently adjusted as new and better data become available. This may be quite frustrating for analysts, since they are never sure whether or by how much the figures are going to be revised
Economic welfare
Many economists argue that GDP and the other national accounting totals are not good measures of economic welfare. They point out, for example, that unwanted by-products (also called negative externalities) such as pollution, congestion and noise are not taken into account. They argue that the value
of these “bads” should be subtracted from the value of “goods” included in GDP
Growth in real GDP may also be accompanied by an increase in the inequality of the distribution of income.
The business cycle
The business cycle is the pattern of upswing (expansion) and downswing (contraction) that can be discerned
in economic activity over a number of years. One complete cycle has four elements: a trough, an upswing or
expansion (often called a boom), a peak, and a downswing or contraction (often called a recession).
Causes of business cycles
Classical economists
Keynesians
Structuralist or institutionalist
Classical economists
Argued that the source of fluctuating in the growth of the economy are due to external factors that are outside the market system since markets are inherently stable
Jevons-changes in weather conditions affecting agricultural activity which was one of the main economic activity of the 19th century
The monetarists, for example, ascribe the fluctuations to faulty or inappropriate government policy which results in fluctuations in the rate of increase in the money stock. These fluctuations then cause changes in the rate of increase in prices, production and employment.
Keynesians economists
Keynesian economists, on the other hand, do not believe that the business cycle is caused by exogenous factors that governments have a duty to intervene in the economy by applying appropriate monetary and fiscal policies
they believe that the business cycle is an endogenous phenomenon. For example, if business conditions improve, such an improvement is reinforced by mechanisms such as the multiplier. A strong upswing therefore results. However, the upswing carries the seeds of its own destruction. As the economy grows, interest rates increase, imports increase, foreign exchange reserves fall, and so on, until a peak is reached. The whole process is then reversed and an economic decline sets in. As the economy declines, interest rates fall, imports decrease, foreign exchange reserves increase, and so
on. This continues until the economy reaches a trough.
government intervention to smooth the peaks and troughs as far as possible. When the economy is in a cyclical downswing, expansionary monetary and fiscal policies are recommended.
When the economy is booming, restrictive measures are proposed.
Structuralist or institutionalist
Changes in economic fluctuations are caused by various
structural or institutional changes. Changes in structure or institutions appropriate economic response will vary from time to time
Measuring business cycle
Economists are regularly confronted by people who want to know whether economic conditions are improving or worsening. What people are really asking is where the economy is on the business
cycle. It takes time so to overcome this problem, economists try to identify certain critical variables or indicators that possibly reflect or predict movements in overall economic activity. These variables are called business cycle indicators.
Business cycle indicators
Leading indicators
Coincident indicators
Lagging indicators
Leading indicators
which tend to peak before the peak in aggregate economic activity and reach a trough before the trough in aggregate economic activity. They thus give advance warning of changes in aggregate economic activity
