Economics: Fiscal Policy, Money Supply, and GDP

Study Notes

Economics: Fiscal Policy, Money Supply, Expenditure Approach, CPI, and GDP (Real and Nominal)

Fiscal Policy

Fiscal policy is a government tool to influence the economy by adjusting taxes and government spending. It is used to manage aggregate demand and stabilize the economy during economic downturns or recessions.

M1 and M2

M1, also known as narrow money, is a measure of money supply that includes cash, checkable deposits, and other easily convertible financial instruments. M2, another measure of money supply, includes M1 plus savings deposits and small-denomination time deposits.

Expenditure Approach

The expenditure approach is a method for measuring GDP that focuses on the total expenditure incurred on goods and services produced within a country during a specific period. It is calculated as the sum of consumption expenditure (C), investment expenditure (I), government expenditure (G), and net exports (X-M), where net exports is the difference between exports (X) and imports (M).

CPI

The Consumer Price Index (CPI) is a measure of inflation that tracks the average change in prices for a basket of consumer goods and services over time. It is widely used by economists and policymakers to monitor inflation and assess the effectiveness of monetary and fiscal policies.

GDP (Real and Nominal)

Gross Domestic Product (GDP) is a measure of a country's economic output, representing the total value of all finished goods and services produced within its borders. It can be measured in either nominal terms (current prices) or real terms (adjusted for inflation). Real GDP is a more accurate measure of the standard of living and economic growth, as it eliminates the effects of inflation and reflects the actual changes in economic activity.

Money Supply and GDP Relationship

The relationship between money supply and GDP is complex and depends on both short-term and long-term perspectives. In the short term, an increase in money supply can lead to a rise in nominal GDP, but this relationship can be less predictable over time. Real GDP, which adjusts for inflation, does not have a clear correlation with the money supply and is more influenced by factors such as productivity and economic agents' behavior.

M1 and M2 Effects on GDP

An increase in the money supply, represented by M1 and M2, can lead to lower interest rates, which in turn can stimulate consumption, investment, and borrowing. In the short term, this can result in higher economic output and spending, potentially contributing to an increase in GDP.

Central Banks and Money Supply

Central banks, such as the U.S. Federal Reserve (Fed) or the European Central Bank (ECB), can influence the money supply by adjusting interest rates and implementing tools such as quantitative easing and credit easing. These policies can help stabilize the economy by managing inflation, promoting growth, and responding to changes in aggregate demand.
