The social multiplier effect is a term used in economics, economic geography, sociology, public health and other academic disciplines to describe certain social externalities. It is based on the principle that high levels of one attribute amongst one's peers can have spillover effects on an individual.
This process continues multiple times, and is called the multiplier effect. The multiplier may vary across countries, and will also vary depending on what measures of money are being considered. For example, consider M2 as a measure of the U.S. money supply, and M0 as a measure of the U.S. monetary base. If a $1 increase in M0 by the Federal ...
The local multiplier effect (sometimes called the local premium) is the additional economic benefit accrued to an area from money being spent in the local economy. The concept has been taken up by advocates for "spend local" campaigns in addition to more formal treatments in the area of regional economic development .
This example shows us how the multiplier is lessened by the existence of an automatic stabilizer and thus helping to lessen the fluctuations in real GDP as a result of changes in expenditure. Not only does this example work with changes in T, it would also work by changing the MPI while holding MPC and T constant as well.
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 approach bunches countries into groups (or "buckets") with similar multiplier values, based on their characteristics, and taking into account the effect of (some) temporary factors such as the state of the business cycle. Different tax and spending choices of equal magnitude have different economic effects: [26] [27] [28]
The above analysis of one target variable and one policy tool can readily be extended to multiple targets and tools. [2] In this case a key result is that, unlike in the absence of multiplier uncertainty, it is not superfluous to have more policy tools than targets: with multiplier uncertainty, the more tools are available the lower expected loss can be driven.
A different paradigm was one of the results of the theories of John Boyd, the "high-low mix" in which a large number of less expensive aircraft, coupled with a small number of extremely capable "silver bullet" aircraft, had the effect of a much larger force. Boyd's concept of quick action is based on the repeated application of the "Boyd loop ...
