ACCESSIBILITY: The location of economic activity (especially in terms of land) relative to other activities. As real estate agents are prone to say, "The three most important factors in real estate are 'location, location, location.'" Accessibility determines how easy or difficult (read this as costly) it is to allocate good, services, and resources. Transportation is a key factor in accessibility. Efficient, low cost transportation systems improve accessibility.

Lesson 12: Business Cycles | Unit 4: Causes Page: 17 of 26

Topic: Complexity <=PAGE BACK | PAGE NEXT=>

Business cycle instability happens, 3 to 4 years of expansion and a year or so of contraction. During each new expansion, we think the business cycle contraction problem has been solved.
  • Every expansion, except the current one, has ended with a contraction. Perhaps we have found THE cause of business cycles and can avoid future contractions.
  • Economy is complex, with many different business cycle causes. Hard to juggle a cell phone, remote control, and lit candle. Eventually you stop and begin again.
Aggregate economic activity is delicate balancing act, with numerous reasons for a contraction.
  • Note that explanations are often influenced by politics and vested interests.

SIMPLE EXPENDITURES MULTIPLIER

A measure of the change in aggregate production caused by changes in an autonomous expenditure that shocks the macroeconomy, when consumption is the ONLY induced expenditure. The simple expenditures multiplier is the inverse of one minus the marginal propensity to consume, or more simply the inverse of the marginal propensity to save. A related multiplier is the simple tax multiplier, which measures the change in aggregate production caused by changes in taxes.

This isn't me! What am I?

There were no banks in colonial America before the U.S. Revolutionary War. Anyone seeking a loan did so from another individual.
