AFL: The abbreviation for the American Federation of Labor, which started as a collection of craft unions in 1886, this is now one half of the umbrella organization for labor unions in the United States (the AFL part of AFL-CIO). As a collection of craft unions, the AFL primarily represented skilled workers in particular occupations. However, it also contained unions representing unskilled industrial workers, which led to a rift among AFL members in 1938 and spawned the formation of the Congress of Industrial Organizations (CIO). This rift was closed in 1955, when both joined together to form the AFL-CIO, which is the primary advocate for workers and labor unions in the United States.

  • Hypotheses from macroeconomic theories are not easily subject to experimental testing. Economists can't control the economy but must wait for it to cooperate.
  • The result of combining different political philosophies and vested interests with the inability to provide definitive explanations, creates alternative, competing theories that seek to explain the world.

MARGINAL PROPENSITY TO SAVE

The proportion of each additional dollar of household income that is used for saving. The marginal propensity to save (abbreviated MPS) is another term for the slope of the saving line and is calculated as the change in saving divided by the change in income. The MPS plays a central role in Keynesian economics. It quantifies the saving-income relation, which is the flip side of the consumption-income relation, and thus it reflects the fundamental psychological law. It is also a critical to the multiplier process. A related saving measure is the average propensity to save.
