![]() ![]() It continues until the deposited amount of $100 converts to $500 as deposits. This process keeps on going as there are more deposits made by people, and banks keep using this deposited amounts for lending purposes. Usually, customers further deposit this amount of $80 in some other bank, which again needs to keep 20% or $16 of the amount as reserves, and lending the remainder of $64. And, the bank can use the remaining amount of $80 for issuing loans to other customers. This 20% translates to keeping $20 reserves for every $100. ![]() For instance, a bank is required to keep 20% reserves for every $100 deposited by the customer. This is the amount of money that results in creating more money, and can be ascertained by dividing total bank deposits by the requirement of reserves. The proportion of deposited funds that banks need to keep as reserves affect the size of the multiplier. When banks start lending more, it leads to increasing the money supply of the nation. ![]() The banking system of a country clearly exhibits the multiplier effect. Say, decline in spendings may cause more unemployment, more reduction in aggregate demand and lesser GDP. ![]() The multiplier effect can have a negative impact too. Multiplier = 1 / (savings + taxes + imports) = 1 / (0.15 + 0.15 + 0.15) = 1 / 0.45 = 2.22 So, this states that an expenditure of $1 would affect or impact the gross domestic product by 2.22. For a better understanding, lets keep all three elements at 15%. The left amount, known as the marginal propensity to consume (MPC), will be something that is used for consumption. While we ascertain the spending multiplier in an open economy considers the percentage of the injection kept separately for leakages including savings, taxes, and imports. Multiplier is calculated by dividing the change in real gross domestic product (GDP) with changes made in injections such as government expenditure, reducing or increasing tax rates and/or interest rates, exports, etc. Considering the marco effects, the multiplier effect ascertains what impact the change in aggregate demand will create on the economic growth. The amount left is used for consumption purposes, and this remaining amount is referred to as marginal propensity to consume.īack to: ECONOMIC ANALYSIS & MONETARY POLICY How Does the Multiplier Effect Work?Ī significant point made in Keynesian economic theory states that aggregate demand can influence economic activity of a nation. Leakages include savings, taxes and imports.
