B. the demand and supply curves don't reflect the full cost of producing a good or service. C. government imposes a tax on a good or service. D. a good or service is not produced because no one demands it. 3. Supply side market failures occur when: A. the demand and supply curves don't reflect consumers' full willingness to pay for a good or service. B. the demand and supply curves don't reflect the full cost of producing a good or service. C. government regulates production of a good or service.

Supply curves must reflect all costs of production, and demand curves must reflect consumers' full willingness to pay. C. Firms must minimize production costs, and consumers must minimize total expenditures. D. Firms must maximize profits, and consumers must all pay prices equal to their maximum willingness to pay. 1 5. Consumer surplus: A. is the difference between the maximum prices consumers are willing to pay for a product and the lower equilibrium price. B. the difference between the maximum prices consumers are willing to pay for a product and the minimum prices producers are willing to accept.

D. improve accountability of government officials, thus leading to more efficient policies. 19. Government officials tend to make: A. better economic decisions than private individuals because of the wealth of information at their disposal. B. better economic decisions than private individuals because of the efficient processes and flexibility built into the government bureaucracy. 5 C. inefficient choices because they lack the information necessary to accurately weigh marginal benefits and marginal costs.
