A lump-sum subsidy has NO EFFECT on a firm's level of output because a lump-sum subsidy does not change marginal costs. It reduces the firm's fixed costs and therefore shifts the average total cost down. This will increase a firm's economic profits, but not change output. If you see lump-sum subsidy or tax, DON'T CHANGE OUTPUT!
