Government Intervention in the economy

Government Intervention in the economy

GOVERNMENT INTERVENTION IN THE ECONOMY SPILLOVER BENEFITS & COSTS When 1 persons consumption of a good provides utility to a 3rd party who has not directly purchased the good, we have spillover benefits Not reflected in the market price of the good AKA. Positive externality

EXAMPLE A home in a neighborhood spends money to professionally landscape their front yard. As a neighbor rides her bike past the yard, she smells the lovely scent of the roses. Although the neighbor did not spend any money on the roses, she is benefitting. AND, ON A GRAPH P S

} P marke t SpilloverD social benefits D private Q market Q social

Q SO, WHAT DOES THIS MEAN? The market demand curve for roses captured the private benefits received by consumers of roses, but not the additional benefits received by neighbors of those who consumed roses The private demand curve, which does not include the spillover benefits, lies below the societal demand curve. The market produces only Qmarket roses, but the optimal amount is greater at Qsocial Since the market produces less than the socially optimal amount, there is an underallocation of resources to rose productionsociety wants more than the market

provides The existence of spillover benefits in a market results in an underallocation of resources in that market= theres not enough of a good thing AND The neighbor provided a public good (community beautification) while the other neighbors were free riders How could we have contributed to the provision

of the public good? SUBSIDIES FOR CONSUMERS Market failures on a larger scale, are remedied through subsidies The goal is to move the EQ from the Qmarket to the Qsocial In the ex. of roses, the govt could provide a subsidy to gardeners, equal to the amount of the spillover benefit

By sending a check to the home who had the yard landscaped, the demand for roses would have increased, & shifted the Dprivate to the Dsocial SUBSIDY FOR CONSUMERS P S Pfirm } Pmarke

Q POLLUTION & SPILLOVER COSTS When a persons consumption of a good imposes a negative utility on a 3rd party who did not purchase the good, we have spillover costs/negative externalities EX. CIGARETTE SMOKE The thought is to move the spillover costs from those who do not smoke, and onto the

producers (hence the cigarette tax) ON A GRAPH P Ssocial Sprivate } spillover cost Pmarket D

Qsocial Qmarket Q COASE THEOREM Ronald Coase is a Nobel Laureate in Economics His theory states that resources can be allocated efficiently if private ownership rights are assigned and when there are no transaction costs. no matter who receives the legal rights to ownership, the assignment will have no effect on the way economic resources are used.

CONTINUED. The Coase Theorem changes the way people look at economic problems. There is less need for govt intervention In any economic transaction, solutions that can benefit most parties can be achieved by negotiations. Ex. Environmental problems can be resolved if property rights are assigned rather than relying on government command & control.

Sounds like the free market to me! PUBLIC CHOICE IS IT RATIONAL FOR GOVERNMENT LEADERS TO FAVOR SPECIAL INTERESTS OVER THE GENERAL PUBLIC INTEREST? The idea is that special interests have a big stake in govt, or a big interest in govt. When special interests give politicians contributions & support, each member of the public may lose just a little when a special interest gets its way, so the public doesnt

pay attention. The public is ignorant. Therefore, the politician goes with the special interest. The more concentrated the benefit for the special interest and the more diffused the cost to the public, the more likely the special interest will get its way. WHY ARE POLITICIANS MAINLY IN THE MIDDLE OF THE ROAD? The median-voter hypothesis predicts

that politicians, regardless of party, will appeal to the median voter in the constituency they represent. It also predicts that politicians will take a more extreme position in the party primary election (when they are appealing to the median voter in the party) than in the general election. ARE PEOPLE RATIONAL OR IRRATIONAL WHEN THEY SPEND LITTLE TIME EVALUATING CANDIDATES BEFORE THEY VOTE AND WHEN THEY DONT VOTE?

This is known as rational ignorance! Why be informed about the candidates when your vote counts so little? Why even vote? If this is true, why do so many people vote? The public-choice answer is that voting is a consumption activity. Voting gives people a feeling that they did their civic duty. By voting, they can complain without guilt when they dont like

a government policy. WHAT IS THE EFFECT OF BUREAUCRATIC ENTREPRENEURS ON GOVERNMENT? A business is successful if it can maximize profits. A bureaucrat is successful if he or she can maximize power. Bureaucrats are rewarded when they expand the duties & clientele of their departments. A bureaucrat will have a smaller department if it becomes more efficient.

Bureaucrats have an incentive to expand their departments, not to reduce them. With larger departments come more power, a bigger office, a higher salary etc. EFFICIENCY, EQUITY & TAX STRUCTURE INCOME DISTRIBUTION & TAX STRUCTURE The govt is also called to action to remedy issues of equity or fairness Markets do not provide equity or fairness

Ex. Some consumers can afford a new Mercedes, come cannot Ex. Some parents can not afford pediatric care for their children EQUITY AS A GOAL Some purpose that economics resources should be equally divided amongst all members of society

Egalitarianism: belief in the equality of all people, especially in political, social, or economic life. Incentive to work hard, take risk or seek a competitive advantage are gone EX. Everyone in class is guaranteed to be compensated with a B regardless of your effort. What does this mean?

C level students wont work hard because their grade will increase anyways A students lack motivation to do well because they are compensated below their quality of work Everyone works less HOW DO WE MEASURE INCOME DISTRIBUTION? Lets see what Reff Enomics has to say!

http ://www.reffonomics.com/TRB/chapter19/Loren zCurveLesson5.swf TAX STRUCTURES Tax: is a mandatory payment to local, state, or natl govt Revenue: is govt income from taxes & other nontax sources.

Revenues raised from taxes fund programs & govt services such as highways, police, education, & parks. Other forms of revenues include lotteries & fees TAX STRUCTURES Equitytax applied uniformly; people in same

situations pay the same Simplicityshould be easy for taxpayers to understand & govt to collect Efficiencyhow well tax raises revenue with least administrative cost & how small the effort & expense are required to pay the tax Criteria

sometimes conflict; a given tax may not meet all TAX STRUCTURES All taxes fall under the classification of 1 of these: Proportional taxflat taxall taxpayers pay same %age of income Ex. Corporate income tax (35%) Progressive taxhigher income earners pay higher

%age of income Ex. Federal Income Tax Regressive taxlower income earners pay higher percentage of income, Ex. sales tax And that ladies & gentlemen is the end of Microeconomics!
