Term | Definition |
---|---|
autonomous change in aggregate spending | an initial rise or fall in aggregate spending that is the cause, not the result, of a series of income and spending changes |
autonomous consumer spending | the amount of money a household would spend if it had no disposable income. |
inventories | stocks of goods and raw materials held to satisfy future sales. |
marginal propensity to consume (MPC) | the increase in consumer spending when income rises by $1. Because consumers normally spend part but not all of an additional dollar of disposable income, MPC is between 0 and 1. |
marginal propensity to save (MPS) | the increase in household savings when disposable income rises by $1. |
multiplier | the ratio of total change in real GDP caused by an autonomous change in aggregate spending to the size of that autonomous change. |
aggregate demand curve | shows the relationship between the aggregate price level and the quantity of aggregate output demanded by households, businesses, the government, and the rest of the world. |
fiscal policy | the use of taxes, government transfers, or government purchases of goods and services to stabilize the economy. |
monetary policy | the central bank's use of changes in the quantity of money or the interest rate to stabilize the economy |
aggregate supply curve | a graphical representation that shows the relationship between the aggregate price level and the total quantity of aggregate output supplied. |
long-run aggregate supply curve | a graphical representation of the relationship between the aggregate price level and the quantity of aggregate output supplied if all prices, including nominal wages, were fully flexible. The long-run aggregate supply curve is vertical. |
potential output | the level of real GDP the economy would produce if all prices, including nominal wages, were fully flexible. |
short-run aggregate supply curve | a graphical representation of the relationship between the aggregate price level and the quantity of aggregate output supplied that exists in the short run, the time period when many production costs can be taken as fixed. |
sticky wages | nominal wages that are slow to fall even in the face of high unemployment and slow to rise even in the face of labor shortages. |
AD/AS model | the basic model used to understand fluctuations in aggregate output and the aggregate price level. It uses the aggregate demand curve and the aggregate supply curve together to analyze the behavior of the economy. |
self-correcting | refers to the fact that in the long run, shocks to aggregate demand affect aggregate output in the short run, but not the long run. |
inflationary gap | exists when aggregate output is above potential output. |
long-run macroeconomic equilibrium | a situation in which the short-run macroeconomic equilibrium is also on the long-run aggregate supply curve; so short-run equilibrium aggregate output is equal to potential output. |
recessionary gap | exists when aggregate output is below potential output. |
stagflation | the combination of inflation and falling aggregate output. |
supply shock | an event that shifts the short-run aggregate supply curve. A negative supply shock raises production costs and reduces the quantity supplied at any aggregate price level, shifting the curve leftward. |
contractionary fiscal policy | fiscal policy that reduces aggregate demand by decreasing government purchases, increasing taxes, or decreasing transfers. |
expansionary fiscal policy | fiscal policy that increases aggregate demand by increasing government purchases, decreasing taxes, or increasing transfers. |
automatic stabilizers | government spending and taxation rules that cause fiscal policy to be automatically expansionary when the economy contracts and automatically contractionary when the economy expands. |
discretionary fiscal policy | fiscal policy that is the direct result of deliberate actions by policy makers rather than rules. |
