PERSONAL TAX AND NONTAX PAYMENTS: The official item in the National Income and Product Accounts maintained by the Bureau of Economic Analysis measuring personal income taxes paid to the government sector on personal income received by the household sector. Personal tax and nontax payments are subtracted from personal income (PI) to calculate disposable income (DI). Personal tax and nontax payments are about 15% of personal income and about 13% of gross domestic product.

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

Every economic analysis builds on certain preconditions or assumptions. Assumptions, whether reasonable or seemingly unrealistic, let us:
  1. Establish abstract benchmarks for comparison or
  2. Break an analysis into simpler, more easily manageable parts.

Four key assumptions:

  • Two Goods: Resources are used to produce one or both of only two goods. This is a simplifying assumption that lets us display graphs on the screen.
  • Fixed Resources: The quantities of the labor, capital, land, and entrepreneurship resources do not change. This is a reasonable assumption that we can change to analysis resource changes.
  • Fixed Technology: The information and knowledge that society has about the production of goods and services is fixed. This is another reasonable assumption that we can change to analysis technology changes.
  • Technical Efficiency: Resources are used in a technically efficient way. We get the maximum possible production out of the resource inputs.

EXCHANGE RATES, AGGREGATE DEMAND DETERMINANT

One of several specific aggregate demand determinants assumed constant when the aggregate demand curve is constructed, and that shifts the aggregate demand curve when it changes. An increase in exchanges rates causes an increase (rightward shift) of the aggregate curve. A decrease in the exchanges rates causes a decrease (leftward shift) of the aggregate curve. Other notable aggregate demand determinants include interest rates, the money supply, inflationary expectations, consumer confidence, and the federal deficit.
