The short-run economies of operation associated with production of an information product arise because: a) AFC is constant and MC slopes downward, so that AVC slopes downward.
b) AVC and AFC slope downward though MC is constant, so that ATC slopes downward.
c) AVC, which is equal to MC, is constant and AFC slopes downward, so that ATC slopes downward.
d) MC is constant and MC slopes upward, so that AVC slopes upward.

The plastic flowerpots company has two manufacturing departments, molding and packaging. at the beginning of the month, the molding department has 2,100 units in inventory, 70% complete as to materials. during the month, the molding department started 18,500 units. at the end of the month, the molding department had 3,150 units in ending inventory, 80% complete as to materials. units completed in the molding department are transferred into the packaging department. cost information for the molding department for the month follows: beginning work in process inventory (direct materials) $ 1,300 direct materials added during the month 28,900 using the weighted-average method, compute the molding department's (a) equivalent units of production for materials and (b) cost per equivalent unit of production for materials for the month. (round "cost per equivalent unit of production" to 2 decimal places.)

Consider how health insurance affects the quantity of health care services performed. suppose that the typical medical procedure has a cost of $160, yet a person with health insurance pays only $40 out of pocket. her insurance company pays the remaining $120. (the insurance company recoups the $120 through premiums, but the premium a person pays does not depend on how many procedures that person chooses to undergo.) consider the following demand curve in the market for medical care. use the black point (plus symbol) to indicate the quantity of procedures demanded if each procedure has a price of $160. then use the grey point (star symbol) to indicate the quantity of procedures demanded if each procedure has a price of $40. q d at p=$160 q d at p=$40 0 10 20 30 40 50 60 70 80 90 100 200 180 160 140 120 100 80 60 40 20 0 price of medical procedures quantity of medical procedures demand if the cost of each procedure to society is truly $160, the quantity that maximizes total surplus is procedures. economists often blame the health insurance system for excessive use of medical care. given your analysis, the use of care might be viewed as excessive because consumers get procedures whose value is than the cost of producing them.

Which one of the following statements is true? ddt does not prevent disease from passing from agricultural animals to humans. cost was a major factor in the united states government's decision to ban ddt. many african governments concluded that the potential long-term health effects of ddt were not as serious as the immediate problem of insect control. ddt cannot accumulate in the fat of animals. the ddt ban in the united states has made it very difficult to control agricultural insect pests.
