ACCELERATOR: The ratio between investment expenditures and the change in gross domestic product. This is based on the notion that business investment depends on the rate of growth of aggregate output. If the economy is expanding, in other words, then the business sector invests in more capital goods to produce the extra output needed. This accelerator effect modifies and magnifies the simply multiplier effect based on the induced consumption and the marginal propensity to consume.

Lesson 11: Circular Flow | Unit 1: Basic Flow Page: 4 of 22

Topic: The Physical Flow <=PAGE BACK | PAGE NEXT=>

Two sectors: household and business.

Two markets: product and factor.

  • The physical flow is the counter-clockwise flow of resources from the household to business sector and production from the business to household sector.
  • Production flows from the business sector (supply) to the household sector (demand) through the product markets.
  • Resources flow from the household sector (demand) to the business (supply) sector through the factor markets.
  • The household sector sells the resources through the factor markets and buy goods through the product markets.
  • The business sector buys resources through the factor markets and sells goods through the product markets.

MARGINAL COST CURVE

A curve that graphically represents the relation between the marginal cost incurred by a firm in the short-run product of a good or service and the quantity of output produced. This curve is constructed to capture the relation between marginal cost and the level of output, holding other variables like technology and resource prices constant. Three related curves are average total cost curve, average variable cost curve, and average fixed cost curve.

This isn't me! What am I?

Paper money used by the Commonwealth of Massachusetts prior to the U.S. Revolutionary War, which was issued against the dictates of Britain, was designed by patriot and silversmith, Paul Revere.
