BEC 5 Flashcards
How is GDP calculated under the expenditure approach?
Hint: GICE
Under the expenditure approach, GDP is calculated by summing the total expenditures in the domestic economy. GDP is calculated as:
Government purchases of goods and services + gross private domestic Investment + personal Consumption expenditures + net Exports (exports minus imports)
How is GDP calculated under the income approach?
Hint: I PIRATED
Under the income approach, GDP is calculated by summing the value of resource costs and incomes generated during the measurement period. GDP is calculated as:
Income of properties + Profits of corporations + Interest (net) + Rental income + Adjustments for net foreign income + Taxes (indirect business taxes) + Employee compensation (wages) + Depreciation (capital consumption allowance)
What are the causes of demand-pull inflation and cost-push inflation?
Demand-pull inflation is caused by increases in aggregate demand. Thus, demand-pull inflation could be caused by factors such as increases in government spending, decreases in taxes, increases in wealth, increases in consumer confidence, and increases in the money supply.
Cost-push inflation is caused by reductions in short-run aggregate supply. Thus, cost-push inflation could be caused by factors such as an increase in oil prices and an increase in nominal wages.
What is the difference between nominal GDP and real GDP?
Nominal GDP measures the value of all final goods and services produced within the borders of a nation in terms of current dollars (i.e., the prices prevailing at the time of production).
Real GDP measures the value of all final goods and services produced within the borders of a nation in terms of constant prices (i.e., the value of goods and services adjusted for changes in the price level). Specifically,
Real GDP = [(Nominal GDP) / (GDP Deflator)] x 100,
where the GDP deflator is the price index used to adjust nominal GDP for changes in the overall prices of goods and services.
Define gross domestic product (GDP).
Gross domestic product is the total market value of all final goods and services produced within the borders of a nation in a particular period. Note that GDP includes the output of foreign owned factories in the U.S., but excludes the output of U.S. owned factories operating abroad.
Explain the relationship between interest rates and the money supply.
Changes in the money supply directly affect interest rates through the money market. An increase in the money supply shifts the money supply curve to the right and causes interest rates to fall. A decrease in the money supply shifts the money supply curve to the left and causes interest rates to rise. Thus, an increase in the money supply leads to a decline in interest rates and a decline in the money supply leads to an increase in interest rates.
List the three ways the Federal Reserve could increase the money supply.
- Open market operations: Purchase government securities on the open market.
- Changes in the discount rate: Lower the discount rate.
- Changes in the required reserve ratio: Lower the required reserve ratio.
What is the likely impact of a decrease in the money supply on interest rates, real GDP, and the overall price level?
A decrease in the money supply leads to an increase in interest rates. As interest rates rise, the cost of capital increases, leading to a decline in investment spending and a shift left in the aggregate demand curve. As the aggregate demand curve shifts left, real GDP and the overall price level fall. Thus, a decrease in the money supply leads to: (1) an increase in interest rates, (2) a decrease in real GDP, and (3) a decrease in the overall price level.
List and define the phases of a typical business cycle.
Business cycles are typically composed of: (1) an expansionary phase characterized by rising growth in economic activity (real GDP); (2) a peak, or high point of economic activity; (3) a contractionary phase characterized by declining growth in economic activity; (4) a trough, or low point of economic activity; and (5) a recovery phase, during which economic activity starts to increase and return to its long-term growth trend.
How is a recession defined?
A recession is defined as a period during which real GDP (national output) is falling for at least two consecutive quarters. Recessions are characterized by falling real output (negative real GDP growth) and rising unemployment.
What is the definition of a business cycle?
Business cycles are defined as the rise and fall of economic activity relative to its long-term growth trend. Business cycles vary in duration and severity. Some cycles are quite mild; others are characterized by large increases in unemployment and/or inflation. Business cycles are also called economic fluctuations.
What are the characteristics of a depression?
A depression is a very severe recession. A depression is characterized by a sustained period of falling real GDP and high rates of unemployment. For example, during the height of the Great Depression, real GDP fell by approximately 33% and one of every four workers was unemployed.
Economists generally agree that business cycles result from what?
Shifts in aggregate demand and aggregate supply.
List the factors that shift aggregate demand.
- Changes in wealth
- Changes in real interest rates
- Changes in expectations about the future economic outlook
- Changes in exchange rates
- Changes in government spending
- Changes in consumer taxes
List the factors that shift short-run aggregate supply.
- Changes in input (resource) prices
- Supply shocks
