Macro 2 Flashcards
The fraction of change in an income that is spent on consumption divided by the change in income that caused it
Marginal propensity to consume
The relationship between consumption and income
Consumption function
The fraction of a change in income that is saved, the change in income that caused it
Marginal propensity to save
The relationship between saving and income
Saving function
The value of assets minus liabilities
Net wealth
Young people borrow, middle ages pay off debt, in order people draw from their savings: on average net savings over a lifetime or small
Lifecycle model of consumption and saving
The relationship between the price level and out put the firms are willing to supply
Aggregate supply
Dollars of the current year
Nominal wage
Dollars of the constant purchasing power
Real wage
The output produced when there are no surprises about the price level
Potential output
The unemployment rate when the economy produces its potential output
Natural rate of unemployment
And macro economics, a period during which the resource prices, especially those of the labor, Are fixed by explicit or implicit agreements
Short run
A curve that shows a direct relationship between the price level in the real GDP supplied in the short run
Short run aggregate supply curve
The price level and real GDP that occur when aggregate demand curve intersects the short run aggregate supply curve
Short run equilibrium
The amount by which output in the short run exceeds the economies potential output
Expansionary GDP
And macro economics, A period. During which wage contracts and resource price agreement can be renegotiated: there are no surprises about the economies actual price level
Long run
The price level in real GDP that occurs when the actual price level equals the expected price level, the real GDP supplied equals potential output, and the real GDP supplied equals the real GDP
Long run equilibrium
The amount by which the actual output in the short run fall short of the economies potential output
Contractionary GDP
A vertical line at the economies potential output: aggregate supply when there are no surprises about the price level and all resource contracts can be re-negotiated
Long run aggregate supply curve
A situation in which workers and employers failed to achieve an outcome they would all prefer
Coordination failure
Unexpected events that affect aggregate supply, sometimes only temporarily
Supply shocks
Unexpected events that increase aggregate supply, sometimes only temporarily
Beneficial supply shocks
Unexpected events that reduce aggregate supply sometimes only temporarily
Adverse supply shocks
The theory that the natural rate of unemployment depends and a part of the recent history of unemployment, high unemployment rates increase the natural rate of employment
Hysteresis
