The social security system in the United States was established by the Social Security Act (1935) in response to the devastating problems of the Great Depression. Our current Social Security system has several parts. The first part, Old Age and Survivors Insurance (OASI) is the one the usually comes to mind when the phrase "Social Security" comes up. It provides benefits to anyone who has reached a certain age and who has paid taxes into the program while employed. It also provides benefits to qualified recipients survivors or dependents. The second part of the system is Disability Insurance (DI), which provides benefits to workers and their dependents in the case of physical disabilities that keeps them from working. The third part is Hospital Insurance (HI), more commonly termed medicare. Medicare provides two types of benefits, hospital coverage for anyone in the OASI part of the system and optional supplemental medical benefits that require a monthly insurance premium. The last part of the social security system is Public Assistance (PA), which is the official term for welfare and is covered under it's own heading.

U-SHAPED COST CURVES: The family of short-run cost curves consisting of average total cost, average variable cost, and marginal cost, all of which have U-shapes. They are U-shaped because each has high but falling cost at low quantities of output, which then reaches a minimum, then has rising cost at larger quantities of output. Although the average fixed cost curve is not U-shaped, it's occasionally included with the other three just for sake of completeness. See also | average total cost | average variable cost | marginal cost | average fixed cost | average total cost curve | average variable cost curve | marginal cost curve | average fixed cost curve | short-run production | stages of production | increasing marginal returns | decreasing marginal returns | law of diminishing marginal returns | total cost | total variable cost | total fixed cost |

SHORT-RUN AGGREGATE SUPPLY CURVE A graphical representation of the short-run relation between real production and the price level, holding all ceteris paribus aggregate supply determinants constant. The short-run aggregate supply, or SRAS, curve is one of two curves that graphical capture the supply-side of the aggregate market. The other is the long-run aggregate supply curve (LRAS). The demand-side of the aggregate market is occupied by the aggregate demand curve. The positive slope of the SRAS curve captures the direct relation between real production and the price level that exists in the short run.
