Document Summary

Diference between total revenue and total cost- proit. Ppf= relaionship between output 1 and output 2. As more labor is used, the marginal product of labor is diminished. Addiional workers are not as producive as previous workers due to crowding of ixed machine. Fixed cost are the money spent on ixed inputs which are constant at all levels of output. Variable costs are the money spent on variable input which depends on the level of output the irm produces. Fixed cost- money on ixed input is on the y-axis and output is on the x-axis: must be a horizontal line (graph) Variable cost- money on variable input on y and output on x: concave graph, slope-marginal cost. Producion funcion- convex graph: input is on x axis and output on y axis, slope is marginal product. Total costs are the sum of the variable and ixed cost. Marginal cost is the extra cost of producing one addiional unit of output.
