During the Revolutionary War, the American colonies could not raise enough tax revenue to fully fund the war effort; to make up the difference, the colonies decided to print more money. Printing money to cover expenditures is sometimes referred to as an inflation tax. Who is being taxed when more money is printed? A- Banks only B- Families of soldiers in active duty C- Anyone who is holding money

Answer is C. When the government prints money, it imposes a tax on anyone who is holding money. This is because printing money decreases the value of money by causing inflation, or an increase in the overall level of prices in the economy. See Section: Principle 9: Prices Rise When the Government Prints Too Much Money.

example of how government can improve market outcomes

Because a type of fish is on the verge of extinction, the government imposes rules that prohibit fishing in the publicly owned spawning grounds. At first, owners of fishing boats complain about this restriction on where they can fish, but soon they notice that the number of adult fish swimming outside the protected area is much higher than it was before. With the restriction, each fishing boat ends up catching more fish than it did before the restriction was in place. Which of the following principles of economic interaction best describes this scenario? When a market outcome is inefficient, government intervention can improve overall welfare. In this case, since the young fish can be caught by any boat owner, the individual pursuit of self-interest leads to a bad outcome—extinction of this type of fish—which makes everyone in the fishing industry worse off. If the government prohibits fishing in the spawning grounds where young fish are born and mature, this motivates boat owners to consider alternatives until the fish mature and reproduce. With this restriction, everyone is better off in the end.

hw example of opportunity cost

Caroline is training for a triathlon, a timed race that combines swimming, biking, and running. Consider the following sentence: Each hour she spends swimming is an hour that she can't spend biking or running. Which basic principle of individual choice does this sentence best illustrate? Answer: All choices have opportunity costs. If Caroline decides to swim, she forgoes the time that she could have spent biking or running. So the opportunity cost of an hour of swimming is an hour of biking or an hour of running, whichever is the highest-valued alternative Kyoko must sacrifice in order to spend an additional hour swimming. There is no information on the effectiveness of an extra hour of swimming as compared to that of an extra hour of biking or running. Therefore, you don't know whether Caroline has an incentive to spend more time on swimming. Similarly, you don't know whether it is most efficient for Caroline to spend the same amount of time on each of the three activities.

Important role for government

What causes inflation?

In almost all cases of large or persistent inflation, the culprit is growth in the quantity of money. When a government creates large quantities of the nation's money, the value of the money falls. In Germany in the early 1920s, when prices were on average tripling every month, the quantity of money was also tripling every month. Although less dramatic, the economic history of the United States points to a similar conclusion: The high inflation of the 1970s was associated with rapid growth in the quantity of money, and the low inflation of more recent experience was associated with slow growth in the quantity of money.

Inflation

Increases in general level of prices

How are inflation and unemployment is related short run?

Increasing the amount of money in the economy stimulates the overall level of spending and thus the demand for goods and services. Higher demand may over time cause firms to raise their prices, but in the meantime, it also encourages them to hire more workers and produce a larger quantity of goods and services. More hiring means lower unemployment.

Marginal Changes

Incremental adjustments to an existing plan.

Long-Run Inflation

Inflation is almost always caused by excessive growth in quantity of money, which causes the value of money to fall

Many decisions are made on the margin. explanation: Neha's decision about pool time versus bike time is a how-much decision. Both bike time and pool time can help reduce her race time. Because pool time seems to be having a greater effect at the moment, it makes sense for her to spend a bit more time in the pool and a bit less time on the bike. However, this does not mean that it makes sense for her to spend all her time in the pool and no time on the bike. If she cut out all training on the bike, the value of a little bit of bike training might be higher than the value of the last hour of pool training. Neha does not treat biking versus swimming as an all-or-nothing decision. She makes small changes at the margin in the number of hours spent training for each activity.

People in the U.S. state of Iowa eat both corn and potatoes. It is technically possible for farmers to grow both corn and potatoes in Iowa, yet almost no farmers grow potatoes. Instead, every year, Iowa exports corn and imports potatoes from the U.S. state of Idaho, where farmers specialize in potatoes. Which of the following principles of economic interaction best describes this scenario? There are gains from trade when producers specialize. Idaho specializes in potatoes, and Iowa specializes in corn. Specialization allows the two states to produce more potatoes and corn as a whole than if both states attempted to produce everything. Trade ensures that people in both states have enough corn and potatoes to eat.

Promoting Efficiency

Public policy may promote efficiency

Why Policymakers should think about incentives?

Public policymakers should never forget about incentives: Many policies change the costs or benefits that people face and, as a result, alter their behavior. A tax on gasoline, for instance, encourages people to drive smaller, more fuel-efficient cars. That is one reason people drive smaller cars in Europe, where gasoline taxes are high, than in the United States, where gasoline taxes are low. When policymakers fail to consider how their policies affect incentives, they often end up with unintended consequences

example of incentive

Suppose that in the hypothetical country of Trashland, garbage cans are distributed to whoever is willing to pay the most. This distribution rule gives the residents of Trashland an incentive to spend time Economists study the choices that people make as they seek to obtain the greatest benefits at the least possible costs. If owning a good will maximize people's benefits in this sense, they will choose to do things to help them obtain that good. As a result, the way that goods are distributed influences how people act. If the distribution of goods is to those willing to pay the most, people have an incentive to spend time earning money to pay for goods. When goods are distributed by price, economists refer to it as a market economy. Different rules for distributing goods will change individuals' incentives. For example, if the next person in line will be awarded a good, people have an incentive to hold their place in the line. Similarly, if a government policy assigns goods to individuals, then people have an incentive to lobby government officials to try to influence the way the goods are given out.

The Social Security system provides income for people over age 65. If a recipient of Social Security decides to work and earn some income, the amount he receives in Social Security benefits is typically reduced.

The provision of Social Security benefits lowers an individual's incentive to save for retirement because it provides income to retired individuals once they've reached age 65. This means that even if an individual hasn't been saving for retirement while working, he can still count on Social Security benefits to support himself through the retirement years. Moreover, because a person gets fewer after-tax Social Security benefits the greater his earnings are, there is also an incentive not to work (or not work as much) once he has hit the retirement age of 65.

Economics

The study of how society manages its scarce resources -How much people decided what to buy, how much to work, save, and spend -How firms decide how much to produce, how many workers to hire -how society decides how to divide its resources between national defense, consumer goods, protecting the environment, and other needs

Suppose Americans decide to save more of their incomes. If banks lend this extra saving to businesses, which use the funds to build new factories, how might this lead to faster growth in productivity? Who do you suppose benefits from the higher productivity? Is society getting a free lunch?

The savings made by people are mobilized by the banks. Banks in turn provide loans to the business firms which use the funds to expand their production by establishing new factories. This leads to faster growth in productivity because when production capacities are increased so is the per capita production. The benefit from the increased productivity is enjoyed by workers, entrepreneurs and all households. Society is not getting a free handout because when people are saving their money there is a trade-off. The people postponing their present needs and saving for the future helps the economy improve productivity.

The requirement to use a safety seat when traveling with young children by air results in more injuries from auto accidents. Which of the following best interprets the statement?

The statement demonstrates that good policies do not guarantee desirable outcomes.

Because the requirement to use a safety seat when traveling with young children by air results in more injuries from auto accidents, all safety regulation must be abandoned.

The statement presents the fallacy of composition. The statement illustrates the fallacy of composition. The fact that the requirement to use a child safety seat during air travel results in more injuries from auto accidents does not imply that all safety regulation should be abandoned. Although good policies do not guarantee desirable outcomes, abandoning all safety regulations may promote reckless behavior and result in even more injuries. Instead, regulators should find an efficient way to address the pitfalls of particular regulations. For example, they may consider requiring airlines to charge lower airfares for children.

Which of the following accurately explains why professional wrestlers earn more than nurses?

The supply of professional wrestlers is small relative to nurses, and price is determined by marginal value (not total value).

example of opportunity cost

The total cost of a choice includes both the actual monetary amount paid and the opportunity cost of your time incurred by making that choice over another. By turning down the cashier job (and going to college), you forgo earning your annual salary of $27,000, so this is the opportunity cost of your time from attending your first year of college. You also choose to pay $34,000 for tuition, supplies, and additional housing expenses. So your total cost of attending your first year of college is over $61,000 . Nevertheless, you decide to attend college, so the value of the benefits must exceed the cost.

Which of the following most accurately explains why the supply curve for a good slopes upward to the right?

There is a direct relationship between a good's price and the amount offered for sale by suppliers.

A 1996 bill reforming the federal government's antipoverty programs limited many welfare recipients to only 2 years of benefits. This change gives people the incentive to find a job ____ quickly than if welfare benefits lasted forever. The loss of benefits after 2 years will result in the distribution of income becoming ____ equal. In addition, the economy will be ____ efficient because of the change in working incentives.

This change gives people the incentive to find a job more quickly than if welfare benefits lasted forever. The loss of benefits after 2 years will result in the distribution of income becoming less equal. In addition, the economy will be more efficient because of the change in working incentives. This change in the government's antipoverty program reduces equality in the distribution of income, since those who cannot find a job will get no income at all; however, the economy is more efficient given the increased incentive for the unemployed to find work and contribute to the nation's output.

Tradeoff

To achieve greater equality, could redistribute income from wealthy to poor. But this reduces incentive to work and produce, shrinks size of economic "pie".

Equality

When prosperity is distributed uniformly among society's members

Efficiency

When society gets the most from its scarce resources

Positive

When the government increases taxes, rates of tax evasion increase.

When monetary policy increases and decreases what happens?

When the government uses monetary policy to decrease the quantity of money, then the demand for goods and services decreases. This change in the demand will lead to lower prices, causing firms to produce fewer goods and services—which requires fewer workers. Therefore, lower prices lead to higher unemployment levels in the short run. When the government uses monetary policy to increase the quantity of money, then the demand for goods and services increases. This change in the demand will lead to higher prices, causing firms to produce more goods and services—which requires more workers. Therefore, higher prices lead to lower unemployment levels in the short run. In the long run, however, an increase in the quantity of money will lead only to an increase in the price levels but will have no effect on the unemployment level. The economy faces a trade-off between inflation—an increase in the overall price levels—and unemployment in the short run. In particular, higher inflation rates usually correspond to lower unemployment levels, while lower inflation rates correspond to higher levels of unemployment.

production possibilities frontier

profit=revenue-costs

profit formula

equality

prosperity/benefits are distributed uniformly among society's members - each portion of the pie is equal to each other tradeoff: to achieve greater equality, could redistribute income from wealthy to poor but this reduces incentive to work and produce and thus shrinks size of total economic pie

Microeconomics

small scale

scarcity

society has limited resources and therefore cannot produce all the goods and services people to wish to have SCARCITY = the limited nature of society's resources

Absence of poverty

some basic level of need has been met

incentive

something (such as prospect of a punishment or reward) that includes a person to act

incentive

something that motivates a person to take an action

example of marginal benefits and costs

spend more on water or diamonds? The reason is that a person's willingness to pay for a good is based on the marginal benefit that an extra unit of the good would yield. The marginal benefit, in turn, depends on how many units a person already has. Water is essential, but the marginal benefit of an extra cup is small because water is plentiful. By contrast, no one needs diamonds to survive, but because diamonds are so rare, people consider the marginal benefit of an extra diamond to be large.

An increase in ________ will cause a movement along a given demand curve, which is called a change in ______

supply, quantity demanded

invisible hand

tendency for market prices to direct individuals pursuing their own self-interests into productive activities that also promote the economic well-being of society

market power

the ability of a single economic order (or small group of actors) to have a substantial influence on market prices ex:if everyone in town needs water but there is only one well, the owner of the well is not subject to the rigorous competition with which the invisible hand normally keeps self-interest in check; she may take advantage of this opportunity by restricting the output of water so she can charge a higher price.

property rights

the ability of an individual to own and exercise control over scarce resources

opportunity cost

the cost of something is what you give up to get it includes not just money but value of time //best alternative use of resource - cost of any action is measured in terms of foregone opportunity opp cost of any item is whatever must be given up to obtain it - it is the relevant cost for decision making

Movie tickets and DVDs are substitutes. If the price of DVDs increases, what happens in the market for movie tickets?

the demand curve shifts to the right

the efficiency of market organization is dependent on 2 things:

competition

the great regulator

opportunity costs

the highest value of alternative sacrificed in order to choose an option incurred when people make choices and they are subjective and vary across people

externality

the impact of one person's actions on the well being of a bystander / production or consumption of good affects bystanders ex: factories polluting

A change in which of the following will not shift the demand curve for hamburgers?

the price of hamburgers

transaction costs

the time, effort, and other resources needed to search out, negotiate, and consummate an exchange

law of comparative advantage

the total output of an economy or trading partners is greatest when each good is produced by person with the lowest opportunity cost for that good

example of tradeoff - giving up something to do something else

there is no such thing as a free lunch, guns and butter (more we spend on national defense the less can spend on consumer goods to raise std of living), have more $ to buy stuff requires working longer hrs which leaves less time for leisure, society deciding between efficiency or equality

what are the broad reasons for a government to intervene in the economy and change the allocation of resources that people would choose on their own?

to promote both efficiency and equality efficiency: think of market failure --> externality+ market power when there is market failure, the government can implement policies to reduce externality. With the example of the factories creating pollution and health problems, the government can make rules to restrict factories polluting. The market power example of a person owning the only water well reminds me of a monopoly and government can have rules to restrict monopolies and trusts. the invisible hand promote efficiency, but not equality. Government can promote both efficiency and equality. For example, making lower income people pay lower taxes than higher income people. Welfare programs. EOP programs.

opportunity cost of production

total economic cost of producing a good or service

True or False: Suppose that the hypothetical country of Kernaland has a chronic scarcity of corn, its staple grain. This implies that there is less corn freely available from nature than residents of Kernaland would like.

true

Because of scarcity it is important

we use resources productively and efficiently

marginal analysis example

when a manager considers whether to increase output, she compares the cost of the needed labor and materials to the extra revenue

incentive example:

when gas prices rise, consumers carpool and buy more hybrids and fewer SUVs, when cigarette taxes increase teen smoking falls, high price in a market provides an incentive for buyers to consume less and an incentive for sellers to produce more
