The quantity theory of money holds that changes in price level are directly related to changes in the money supply. Most economists believe that this relationship explains long-run changes in the price level.
For example, a decrease in demand due to a recession can lead to lower price levels and deflation. A negative supply shock, such as an oil crisis, lowers aggregate supply and can cause inflation. The AD-AS model has become the standard textbook model for explaining the macroeconomy.
The aggregate demand curve's downward slope means that more output is demanded at lower price levels. The AD—AS diagram can model a variety of macroeconomic phenomena, including inflation. Changes in the non-price level factors or determinants cause changes in aggregate demand and shifts of the entire aggregate demand AD curve.
When demand for goods exceeds supply there is an inflationary gap where demand-pull inflation occurs and the AD curve shifts upward to a higher price level. When the economy faces higher costs, cost-push inflation occurs and the AS curve shifts upward to higher price levels. The IS—LM model gives the underpinnings of aggregate demand itself discussed above. The Solow model assumes that labor and capital are used at constant rates without the fluctuations in unemployment and capital utilization commonly seen in business cycles.
An increase in the savings rate leads to a temporary increase as the economy creates more capital, which adds to output. However, eventually the depreciation rate will limit the expansion of capital: savings will be used up replacing depreciated capital, and no savings will remain to pay for an additional expansion in capital. Solow's model suggests that economic growth in terms of output per capita depends solely on technological advances that enhance productivity.
This group of models explains economic growth through other factors, such as increasing returns to scale for capital and learning-by-doing , that are endogenously determined instead of the exogenous technological improvement used to explain growth in Solow's model.
Both forms of policy are used to stabilize the economy , which can mean boosting the economy to the level of GDP consistent with full employment. Typically, central banks take action by issuing money to download bonds or other assets , which boosts the supply of money and lowers interest rates, or, in the case of contractionary monetary policy, banks sell bonds and take money out of circulation.
Usually policy is not implemented by directly targeting the supply of money. Central banks continuously shift the money supply to maintain a targeted fixed interest rate. Some of them allow the interest rate to fluctuate and focus on targeting inflation rates instead.
Central banks generally try to achieve high output without letting loose monetary policy that create large amounts of inflation. Conventional monetary policy can be ineffective in situations such as a liquidity trap. When interest rates and inflation are near zero, the central bank cannot loosen monetary policy through conventional means. An example of intervention strategy under different conditions Central banks can use unconventional monetary policy such as quantitative easing to help increase output.
Instead of downloading government bonds, central banks can implement quantitative easing by downloading not only government bonds, but also other assets such as corporate bonds, stocks, and other securities. This allows lower interest rates for a broader class of assets beyond government bonds. In another example of unconventional monetary policy, the United States Federal Reserve recently made an attempt at such a policy with Operation Twist.
Unable to lower current interest rates, the Federal Reserve lowered long-term interest rates by downloading long-term bonds and selling short-term bonds to create a flat yield curve. Further information: Fiscal policy Fiscal policy is the use of government's revenue and expenditure as instruments to influence the economy.
Examples of such tools are expenditure , taxes , debt. For example, if the economy is producing less than potential output, government spending can be used to employ idle resources and boost output. Government spending does not have to make up for the entire output gap. There is a multiplier effect that boosts the impact of government spending.
For instance, when the government pays for a bridge, the project not only adds the value of the bridge to output, but also allows the bridge workers to increase their consumption and investment, which helps to close the output gap.
The effects of fiscal policy can be limited by crowding out. When the government takes on spending projects, it limits the amount of resources available for the private sector to use.
Crowding out occurs when government spending simply replaces private sector output instead of adding additional output to the economy.
Crowding out also occurs when government spending raises interest rates, which limits investment. Defenders of fiscal stimulus argue that crowding out is not a concern when the economy is depressed, plenty of resources are left idle, and interest rates are low. Automatic stabilizers do not suffer from the policy lags of discretionary fiscal policy.
