MARGINAL COST: The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost indicates how much total cost changes for a give change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (remember total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. Marginal cost, usually abbreviated MC, is found by dividing the change in total cost (or total variable cost) by the change in output.

Election seeking politicians who undertake risks inherent in the allocation of resources made through government actions. Like business entrepreneurs, political entrepreneurs take risks and organize production. They organize production with government laws, regulations, and policies. They run the risk of failed policies and losing elections. Their utility-maximizing actions are also a prime source of government failure. Falling victim to the principal-agent problem, pursuit of their own satisfaction (winning elections) often conflicts with what is best for the rest of society.
