Discuss which principles of economics directly relate to your purchasing decision of a new house

The four principles of economic decisionmaking are: People face tradeoffs because to get one thing that they like, they usually have to give up another thing that they like. The cost of something is what you give up to get it, not just in terms of monetary costs but all opportunity costs. Rational people think at the margin by taking an action if and only if the marginal benefits exceed the marginal costs.

People respond to incentives because as they compare benefits to costs, a change in incentives may cause their behavior discuss which principles of economics directly relate to your purchasing decision of a new house change. The three principles concerning economic interactions are: Trade can make everyone better off because it allows countries to specialize in what they do best and to enjoy a wider variety of goods and services.

Markets are usually a good way to organize economic activity because the invisible hand leads markets to desirable outcomes. Governments can sometimes improve market outcomes because sometimes markets fail to allocate resources efficiently because of an externality or market power. The three principles that describe how the economy as a whole works are: Prices rise when the government prints too much money because more money in circulation reduces the value of money, causing inflation. Society faces a short-run tradeoff between inflation and unemployment that is only temporary and policymakers have some ability to exploit this relationship using various policy instruments.

Questions for Review 1. Examples of tradeoffs include time tradeoffs such as studying one subject over another, or studying at all compared to engaging in social activities and spending tradeoffs such as whether to use your last ten dollars on pizza or on a study guide for that tough economics course.

The opportunity cost of seeing a movie includes the monetary cost of admission plus the time cost of going to the theater and attending the show. The time cost depends on what else you might do with that time; if it's staying home and watching TV, the time cost may be small, but if it's working an extra three hours at your job, the time cost is the money you could have earned.

The marginal benefit of a glass of water depends on your circumstances. If you've just run a marathon, or you've been walking in the desert sun for three hours, the marginal benefit is very high. But if you've been drinking a lot of liquids recently, the marginal benefit is quite low. The point is that even the necessities of life, like water, don't always have large marginal benefits. Policymakers need to think about incentives so they can understand how people will respond to the policies they put in place.

The text's example of seat belts shows that policy actions can have quite unintended consequences. If incentives matter a lot, they may lead to a very different type of policy; for example, some economists have suggested putting knives in steering columns so that people will drive much more carefully!

While this suggestion is silly, it highlights the importance of incentives. Trade among countries isn't a game with some losers and some winners because trade can make everyone better off. By allowing specialization, trade between people and trade between countries can improve everyone's welfare. The "invisible hand" of the marketplace represents the idea that even though individuals and firms are all acting in their own self-interest, prices and the marketplace guide them to do what is good for society as a whole.

The two most important causes of market failure are externalities and market power. Market power refers to the ability of a single person or small group of people to unduly influence market prices, such as in a town with only one well or only one cable television company. In addition, a market economy also leads to an unequal distribution of income.

Productivity is important because a country's standard of living depends on its ability to produce goods and services.

The greater a country's productivity the amount of goods and services produced from each hour of a worker's timethe greater will be its standard of living. Inflation is an increase in the overall level of prices in the economy.

Inflation is caused by increases in the quantity of a nation's money. Inflation and unemployment are negatively related in the short run. Reducing inflation discuss which principles of economics directly relate to your purchasing decision of a new house costs to society in the form of higher unemployment in the short run. Problems and Applications 1. A family deciding whether to buy a new car faces a tradeoff between the cost of the car and other things they might discuss which principles of economics directly relate to your purchasing decision of a new house to buy.

For example, buying the car might mean they must give up going on vacation for the next two years. So the real cost of the car is the family's opportunity cost in terms of what they must give up. For a member of Congress deciding whether to increase spending on national parks, the tradeoff is between parks and other spending items or tax cuts. If more money goes into the park system, that may mean less spending on national defense or on the police force. Or, instead of spending more money on the park system, taxes could be reduced.

When a company president decides whether to open a new factory, the decision is based on whether the new factory will increase the firm's profits compared to other alternatives. For example, the company could upgrade existing equipment or expand existing factories. The bottom line is: Which method of expanding production will increase profit the most? In deciding how much to prepare for class, a professor faces a tradeoff between the value of improving the quality of the lecture compared to other things she could do with her time, such as working on additional research.

When the benefits of something are psychological, such as going on a vacation, it isn't easy to compare benefits to costs to determine if it's worth doing. But there are two ways to think about the benefits. One is to compare the vacation with what you would do in its place. If you didn't go on vacation, would you buy something like a new set of golf clubs? Then you can decide if you'd rather have the new clubs or the vacation.

A second way is to think about how much work you had to do to earn the money to pay for the vacation; then you can decide if the psychological benefits of the vacation were worth the psychological cost of working. If you are thinking of going skiing instead of working at your part-time job, the cost of skiing includes its monetary and time costs, which includes the opportunity cost of the wages you are giving up by not working.

If the choice is between skiing and going to the library to study, then the cost of skiing is its monetary and time costs including the cost to you of getting a lower discuss which principles of economics directly relate to your purchasing decision of a new house in your course. The idea that money has a time value is the basis for the field of finance, the subfield of economics that has to do with prices of financial instruments like stocks and bonds.

What matters now is the chance to earn profits at the margin. So what matters is not the total profit, but the profit you can earn at the margin.

Harry suggests looking at whether productivity would rise or fall. Productivity is certainly important, since the more productive workers are, the lower the cost per gallon of potion.

Ron wants to look at average cost. A firm wants to maximize its profits, so it needs to examine both costs and revenues.

Hermione is the only one who is thinking at the margin. The benefits provide some level of income to the individual when he or she retires.

This means that the individual is not entirely dependent on savings to support consumption through the years in retirement. Since a person gets fewer after-tax Social Security benefits the greater is his or her earnings, there is an incentive not to work or not work as much after age 65.

The more you work, the lower your after-tax Social Security benefits will be. Thus the taxation of Social Security benefits discourages work effort after age 65. When welfare recipients who are able to work have their benefits cut off after two years, they have greater incentive to find jobs than if their benefits were to last forever.

The loss of benefits means that someone who can't find a job will get no income at all, so the distribution of income will become less equal. But the economy will be more efficient, since welfare recipients have a greater incentive to find jobs. Thus the change in the law is one that increases efficiency but reduces equity.

By specializing in each task, you and your roommate can finish the chores more quickly. If you divided each task equally, it would take you more time to cook than it would take your roommate, and it would take him more time to clean than it would take you. By specializing, you reduce the total time discuss which principles of economics directly relate to your purchasing decision of a new house on chores. Similarly, countries can specialize and trade, making both better off.

For example, suppose it takes Spanish workers less time to make clothes than French workers, and French workers can make wine more efficiently than Spanish workers.

Then Spain and France can both benefit if Spanish workers produce all the clothes and French workers produce all the wine, and they exchange some wine for some clothes. Being a central planner is tough! To produce the right number of CDs by the right artists and deliver them to the right people requires an enormous amount of information.

You need to know about production techniques and costs in the CD industry. You need to know each person's musical tastes and which artists they want to hear. If you make the wrong decisions, you'll be producing too many CDs by artists that people don't want to hear, and not enough by others. Your decisions about how many CDs to produce carry over to other decisions. You have to make the right number of CD players for people to use.

3.1 Factors That Influence Consumers’ Buying Behavior

If you make too many CDs and not enough cassette tapes, people with cassette players will be stuck with CDs they can't play. The probability of making mistakes is very high. You will also be faced with tough choices about the music industry compared to other parts of the economy.

If you produce more sports equipment, you'll have fewer resources for making CDs. So all decisions about the economy influence your decisions about CD production. The market failure comes from the monopoly by the cable TV firm.

An externality arises because secondhand smoke harms nonsmokers. The market failure occurs because of Standard Oil's monopoly power.

Principles of Economics/Solutions

There is an externality because of accidents caused by drunk drivers. If everyone were guaranteed the best health care possible, much more of our nation's output would be devoted to medical care than is now the case. Would that be efficient? If you think that currently doctors form a monopoly and restrict health care to keep their incomes high, you might think efficiency would increase by providing more health care.

But more likely, if the government mandated increased spending on health care, the economy would be less efficient because it would give people more health care than they would choose to pay for.
