Conversely, any economic quantity that is negatively correlated with the overall state of the economy is said to be countercyclical. [3] That is, quantities that tend to increase when the overall economy is slowing down are classified as 'countercyclical'. Unemployment is an example of a countercyclical variable. [4]
The multiplier–accelerator model can be stated for a closed economy as follows: [3] First, the market-clearing level of economic activity is defined as that at which production exactly matches the total of government spending intentions, households' consumption intentions and firms' investing intentions.
The circular flow of income is a concept for better understanding of the economy as a whole and for example the National Income and Product Accounts (NIPAs). In its most basic form it considers a simple economy consisting solely of businesses and individuals, and can be represented in a so-called "circular flow diagram." In this simple economy ...
A positive causal link can be said to lead to a change in the same direction, and an opposite link can be said to lead to change in the opposite direction, i.e. if the variable in which the link starts increases, the other variable decreases and vice versa. The words without arrows are loop labels.
Some sources argue identifying any such patterns as a "cycle" is a misnomer, because of their non-cyclical nature. [1] Economists using efficient-market hypothesis say that asset prices reflect all available information meaning that it is impossible to systematically beat the market by taking advantage of such cycles.
Cyclical dynamics at the level of individual industries may present rather different patterns from those of the general business cycles. For example, while the fluctuations of many industries correlate with those in the aggregate economy, there were also many industries that are not sensitive to business cycles — such as the pharmaceutical ...
Okun's law is an empirical relationship. In Okun's original statement of his law, a 2% increase in output corresponds to a 1% decline in the rate of cyclical unemployment; a 0.5% increase in labor force participation; a 0.5% increase in hours worked per employee; and a 1% increase in output per hours worked (labor productivity).
'Sunspots' have been included in economic models as a way of capturing these 'extrinsic' fluctuations, in fields like asset pricing, financial crises, [3] [4] business cycles, economic growth, [5] and monetary policy. [6] Experimental economics researchers have demonstrated how sunspots could affect economic activity. [7]
