Macro Economics Flashcards
Aggregate Demand (AD)
Total level of demand for desired goods and services (at any time by all groups within a national economy) that makes up the gross domestic product (GDP).
Aggregate demand is the sum of consumption expenditure, investment expenditure, government expenditure, and net exports.
Aggregate demand is the total amount of expenditures for consumer goods and investment for a period of time. It includes purchases by consumers, businesses, government, and foreign entities.
Aggregate Demand (AD)
In macroeconomics, Aggregate Demand (AD) or Domestic Final Demand (DFD) is the total demand for final goods and services in an economy at a given time.
It is often called effective demand, though at other times this term is distinguished. This is the demand for the gross domestic product of a country.
Aggregate Demand can increase or decrease depending on several things. In effect, these things will cause shifts up or down in the AD curve. These include: Exchange Rates: When a country’s exchange rate increases, then net exports will decrease and aggregate expenditure will go down at all prices.
Aggregate Demand (AD)
There are four components of Aggregate Demand (AD);
- Consumption (C)
- Investment (I)
- Government Spending (G)
- Net Exports (X-M)
Aggregate Demandshows the relationship between Real GNP and the Price Level
Central Bank
The central bank’s most important function is to regulate the money supply in accordance with policies established to promote the nation’s economic well-being.
Monetary policy seeks to provide a supply of money, employment, and a relatively stable price level.
Control of Money Supply
- Open market operations through bond sales and purchases are flexible (government securities can be purchased or sold in large or small amounts), cause prompt changes in bank reserves, and are more subtle than reserve ratio changes.
- The amount of commercial bank reserves obtained by borrowing from the central bank is small and because whether a change in the discount rate has much impact depends on whether the change occurs at a time when the commercial banks are inclined to alter their central bank borrowings.
CPI vs PPI
The CPI is measured as the price that urban consumers paid for a fixed basket of goods and services in relation to the price of the same goods and services purchased in some base period.
The producer price index (PPI) is the measure used by companies.
The price index measures the combined price of a selected group of goods and services for a specified period in comparison with the combined price of the same or similar goods for a base period. The U.S. government’s producer price index (PPI) is an example. It measures the price of a basket of 3,200 commodities at the point of their first sale by producers.
Deflation
Deflation is a general decline in prices of goods and services.
Demand Pull Inflation
The most effective government fiscal policy would involve reducing demand that could be done by increase in taxation and reduced government spending.
Discount Rate
The discount rate is the rate of interest banks pay when they borrow from a Federal Reserve Bank in order to maintain reserve requirements.
An increase in the discount rate (i.e., a bank’s cost of borrowing) tends to increase the rate banks charge for loans, which tends to have a ripple effect on interest rates charged by others.
Expansionary Monetary Policy
Expansionary monetary policy is when a central bank uses its tools to stimulate the economy. That increases the money supply, lowers interest rates, and increases aggregate demand.
Frictional Unemployment
Frictional unemployment measures the temporary unemployment that always exists as workers change jobs or new workers enter the workforce.
Major Components of Real Gross Domestic Product
- Total worker hours
- Labor Productivity
Marginal Propensity To Consum
The marginal propensity to consume (MPC) is the proportion of an aggregate raise in pay that a consumer spends on the consumption of goods and services, as opposed to saving it.
Marginal propensity to consume is a component of Keynesian macroeconomic theory and is calculated as the change in consumption divided by the change in income. MPC is depicted by a consumption line, which is a sloped line created by plotting change in consumption on the vertical “y” axis and change in income on the horizontal “x” axis.
Multiplier Effect
The multiplier provides an indication of the impact of an increase in consumption or investment in GDP. An increase in spending ripples through the economy because individuals and business save only a portion of the increase in income.
Recession
Recession is a contraction in the economy.
