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: multiplier and crowding out effects

    Multiplier effect: whenever   any of the components of AD increases, the increase in GDP will be greater than the initial increase in expenditures. The impact on GDP of a particular increase in spending depends on the proportion of the new income that is taken out of the system to the proportion that continues to circulate in the economy. The multiplier effect tells us the impact a particular change in one the components of AD will have on the total income (GDP).  Let k denote the spending multiplier, which is a function of MPC and MPS. The larger the marginal propensity to consume, the larger the spending multiplier. Notice that the larger the MPC, the greater the impact a particular change in the spending variables will have on the nation's GDP. The crowding out effect: If government spending increases without an increase in taxes, the government must borrow funds from the private sector to finance its deficit, thereby increasing the interest rate. This increase in interest ...

    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...

    Microeconomics: Factor Markets

    Definition: Factor markets: markets for the factors of production (example: labor and capital). Markets are formed whenever consumers and producers meet to exchange goods or services. Deriving factor demand: the demand for goods or services in the product markets creates demand for the factors of production.  An increase (decrease) in demand for good X leads the suppliers to increase their production thereby increasing (decreasing) the demand for the factors of production.   Marginal revenue product: The demand for the factor of production is formed by multiplying a firm's marginal revenue by its marginal product.  Remember that by taking the derivative of the TR function with respect to Q we are able to find the MR. Marginal product on the other hand is found by taking the derivative of the production function with respect to a factor of production (L or K for example). Marginal revenue product (MRP): the change in total revenue when one more input is employed. It decrea...
