1.A profit maximizing dairy farm is currently producing 10,000 gallons of milk per day. The government is considering two alternative policies. One is to give the farm a lump sum subsidy of $500 per month. The other policy is to give the farm a subsidy of $.05 per gallon of output.
A:Both kinds of subsidy will increase production at this farm. B:Which subsidy has the greater effect on production at this farm depends on whether fixed costs are greater than variable costs. C:Neither subsidy will affect production at this farm, since output is determined by profit maximization.
