WELFARE: An assortment of programs that provide assistance to the poor. The cornerstone of our welfare system is Aid to Families with Dependent Children (AFDC), which was created by the Social Security Act (1935). It provides cash benefits to assist needy families with children under the age of 18. Funding comes partly from the federal government and partly from states. Because states also administer their own programs, benefits and qualification criteria differ from state to state. A second part of the welfare system, one that's run entirely by the federal government, is Supplemental Security Income (SSI). This program provides cash benefits to elderly, blind, and disabled in addition to any benefits received through the Social Security system. Our welfare system includes a whole bunch of additional benefits, including Medicaid, food stamps, low-cost housing, school lunches, job training, day care, and earned-income tax credits.

                           MARGINAL REVENUE PRODUCT CURVE: A curve that graphically illustrates the relation between marginal revenue product and the quantity of the variable input, holding all other inputs fixed. This curve indicates the incremental change in total revenue for incremental changes in the variable input. The marginal revenue product curve plays a key role in marginal productivity theory and the economic analysis of factor markets. The marginal revenue product curve indicates how marginal revenue product is related to the quantity of a variable input used in production. While the analysis of factor markets tends to focus on labor as the variable input, a marginal revenue product curve can be constructed for any input.| Marginal Revenue Product Curve |  |
This diagram graphically illustrates the relation between marginal revenue product and the variable input. This particular curve is derived from the hourly production of Super Deluxe TexMex Gargantuan Tacos (with sour cream and jalapeno peppers) as Waldo's TexMex Taco World restaurant employs additional workers. The number of workers, measured on the horizontal axis, ranges from 0 to 10 and the revenue generated from the marginal production of Gargantuan Taco attributable to each extra worker, measured on the vertical axis. This variable ranges from -$20 to $60.The shape of this marginal revenue product curve is most important. For the first two workers of variable input, marginal revenue product increases, as each added worker contributes more to total revenue than previous workers. This is reflected in a positive slope of the marginal revenue product curve. From the third worker on, the marginal revenue product declines, as each added worker contributes less to total revenue than previous workers. This is seen as a negative slope. The hump-shape of the marginal revenue product curve embodies the essence of the analysis of short-run production. The upward-sloping portion of the marginal revenue product curve, up to the second worker, is due to increasing marginal returns. Decreasing marginal returns sets in after the marginal revenue product curve peaks with the second worker and declines for the third worker. In particular, this declining segment of the marginal revenue product curve reflects the law of diminishing marginal returns. This marginal revenue product curve is THE key ingredient for deriving the factor demand curve.

Today, you are likely to spend a great deal of time visiting every yard sale in a 30-mile radius trying to buy either a decorative windchime with plastic or a flower arrangement for that special day for your mother. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
