 ARBITRATION: Intervention of an impartial third party to settle disputes between two others. The decisions of this third party -- the arbitrator -- are legally binding, much like the ruling of a judge in a court of law. Arbitration is commonly used to interpret a collective bargaining agreement between unions and employers. Much like a judge (in some cases it is a judge) an arbitrator determines how a given union and employer conflict stacks up against the terms of existing agreement. Note that an arbitrator doesn't try to decide what's "best, "fair," or mutually agreeable to both sides -- as would be the case with mediation -- but only what's in line with the existing agreement.

 Lesson 12: Elasticity and Demand | Unit 3: Measurement Page: 10 of 25

 Topic: Doing The Numbers <=PAGE BACK | PAGE NEXT=>

• Suppose we have the following price and quantity values for the demand of calling minutes in cellular phones:

P1 = 10 cents, Q1 = 5 million minutes, P2 = 11 cents, and Q2 = 4.5 million minutes.

• Plugging theses numbers into the formula gives us:

 elasticity = - 0.105 ÷ 0.095 = - 1.105

• While the quick and dirty elasticity indicates exactly unit elastic demand (1 on the nose), the midpoint formula indicates relatively elasticity demand (1.105).

INDUCED GOVERNMENT PURCHASES

Government purchases that depend on income or production (especially national income and gross domestic product). That is, changes in income induce changes in government purchases. Induced government purchases reflect the observation that the government sector (especially state and local governments) is inclined to use tax revenue, which increases with income, for purchases. They are measured by the marginal propensity for government purchases (MPG) and are reflected by the positive slope of government purchases line. The alternative to induced government purchases is autonomous government purchases, which do not depend on income.
