Macroeconomics: different types of inflation and methods to stabilize inflation

 

Types of inflation:

  • Demand pull inflation: caused by a rightward shift in the aggregate demand. The increased in consumption among consumers for a limited amount of goods forces prices to rise.
    • When the economy is below full employment, an increase in AD does not drastically change the price level, since the economy is not fully using its resources (workers and machines) and can therefore easily increase production.
    • When the economy is at full employment, an increase in AD causes a large increase in inflation, it becomes relatively more costly to increase production.
  • Methods for reducing demand pull inflation:
    • Contractionary fiscal policies: raising taxes or reducing the government spending, will put downward pressure on the aggregate demand, and thereby reduces its rightward shift.
    • Contractionary monetary policies: Usually, the central bank is the entity that deals with inflation. It does so by increasing the federal funds rate through open market transaction, which decreases the supply of money in the system.
  • Cost-push inflation: caused by an increase in the cost of production, a shift in the short run aggregate supply to the left.
    • This can be caused by an increase in the price of raw materials, or in energy and transportation cost. Higher business taxes can also have this effect.
  • Methods for reducing cost-push inflation:
    • Contractionary demand side policies: will reduce inflation by shifting the AD to the left, however, it will also increase the unemployment level and increase the level of economic contraction. Might need a larger fiscal and monetary stimulus in the future.
    • Expansionary supply side policies: corrects both the unemployment and inflation levels. Here are a few examples: reducing business taxes, minimum wage, subsidies for energy or transportation.

    Macroeconomics: real vs nominal gross domestic product

    Nominal GDP:   A nominal GDP measures the value of a nation's output produced in a year, given the prices charged for that year. However, if prices increase while the output level stays constant in a given year, the nominal GDP will drastically increase, even though the level of production is equal to that of the previous year. Estimating real GDP: To determine the actual change in output from one year to the next, we must adjust the nominal value of a country's output in a year based on changes in the average price level during that year.  Inflation is when the price level increases, whereas deflation is when the price level is decreasing. To determine whether the nominal GDP overestimates or underestimates the output of a country, one must know whether the average price level has increased or decreased. In order to achieve this task can use a price index known as the GDP deflator. The GDP deflator: Real GDP is calculated by replacing the prices for that current year with tho...

    Microeconomics: Firms and cost in the short run

    In Economics, the term short run refers to a time period where at least one variable of interest does not change . In our case, the short run for a firm is when at least one input  (labor, land, capital) stays fixed. Usually land and capital are considered fixed in the short run.  If an input is fixed during a period time, no matter how much the total product a firm produces, its cost stays the same. This cost is commonly known as fixed cost (FC). Examples of fixed costs: rent, property taxes, loan payments. Labor is often considered to be a part of the  variable cost (VC) . Variable cost can be defined as the cost a firm has control over during the short run. Unlike fixed cost, variable cost increases (decreases) as a firm's total product increases (decreases). Examples of variable costs include: utility bills, wages, raw materials A firm's total cost (TC) is the sum of its variable and fixed costs. As you can see, the fixed cost...

    Macroeconomics: the money market and loanable funds market

      The money market: The money market combines the supply of money and the demand for money for a country. The supply curve (Sm) is inelastic and is determined by the central bank. The demand curve (Dm) is the horizontal summation of the asset and transaction demand curves and is sloping downward. The intersection between the Sm and Dm is the equilibrium interest rate for a country. A change in the nominal interest rate implies that either or both curves (i.e Sm and Dm) have shifted to the right or left. An increase in nominal GDP (P*Y) will lead to an increase in the transaction demand for money which will shift the total demand (Dm) to the right. The nominal interest rate goes up. A decrease in the level of output (Y) will shift the Dm curve to the left. The Sm curve will shift whenever the central bank decides to change the money supply due to a monetary policy decision. The Fed expands the supply of excess reserves in commercial banks, by purchasing bonds from banks, Sm shi...
