The insights developed in the coming chapters will give you a new perspective on how best to make these decisions. Studying economics will not by itself make you rich, but it will give you some tools that may help in that endeavor. The third reason to study economics is that it will give you a better understanding of both the potential and the limits of economic policy.
What are the burdens associated with alternative forms of taxation? What are the effects of free trade with other countries? What is the best way to protect the environment? How does a government budget deficit affect the economy? An understanding of economics will help you carry out that responsibility. And who knows: Perhaps someday you will end up as one of those policymakers yourself. Like, the other book Principles of Macroeconomics , it also contains several parts.
There are seven parts in total. First 3 parts of Microeconomics books are same as Macroeconomics. Both sister books also have the common initial chapters. In these chapters, the reader gets an overview of what economics is? Then afterwards, there is a division in both the books. Meanwhile, Fourth part deals with the public sector economy. It puts special emphasis on public goods. The tax system affecting the economic power of consumers is also discussed in separate chapter.

The most recent significant models rejuvenate microeconomic standards. Acclaimed text creator N. Gregory Mankiw clarifies, "I have attempted to place myself in the situation of somebody seeing financial aspects just because.
I will likely underline the material that understudies ought to and do discover intriguing about the investigation of the economy.

While it seems as if economists do not agree on much, this is in fact not true. Table 1 contains 20 propositions that are endorsed by a majority of economists. Table 1 2. Almost all economists believe that rent control adversely affects the availability and quality of housing.
Most economists also oppose barriers to trade. Ask the Experts: Ticket Resale 1. In this case, ask students their opinion on ticket scalping laws. Discuss the opportunity for potential audience members to pay a price higher than the stated ticket price to be able to attend the event rather than be excluded from the event because there are no more tickets available at the stated ticket price.
Training in economics helps us to understand fallacies and to anticipate unintended consequences. This excerpt from a commencement address by Robert D. McTeer, Jr. Appendix—Graphing: A Brief Review Many instructors may be unaware of how much trouble beginning students have grasping the most basic graphs.
It is important for instructors to make sure that students are comfortable with these techniques. Pie Chart 2. Bar Graph 3. Time-Series Graph B. Economists are often concerned with relationships between two or more variables. Ordered pairs of numbers can be graphed on a two-dimensional grid.
The first number in the ordered pair is the x-coordinate and tells us the horizontal location of the point. The second number in the ordered pair is the y-coordinate and tells us the vertical location of the point.
The point with both an x-coordinate and y-coordinate of zero is called the origin. Two variables that increase or decrease together have a positive correlation. Two variables that move in opposite directions one increases when the other decreases have a negative correlation. Curves in the Coordinate System 1. Often, economists want to show how one variable affects another, holding all other variables constant.
Table A-1 Figure A-3 a. An example of this is a demand curve. The demand curve shows how the quantity of a good a consumer wants to purchase varies as its price varies, holding everything else such as income constant. If income does change, this will alter the amount of a good that the consumer wants to purchase at any given price. Thus, the relationship between price and quantity desired has changed and must be represented as a new demand curve.
A simple way to tell if it is necessary to shift the curve is to look at the axes. When a variable that is not named on either axis changes, the curve shifts. Slope Figure A-5 1. We may want to ask how strongly a consumer reacts if the price of a product changes. If the demand curve is very steep, the quantity desired does not change much in response to a change in price. If the demand curve is very flat, the quantity desired changes a great deal when the price changes.
A small slope in absolute value means that the demand curve is relatively flat; a large slope in absolute value means that the demand curve is relatively steep.
Cause and Effect 1. Economists often make statements suggesting that a change in Variable A causes a change in Variable B. Ideally, we would like to see how changes in Variable A affect Variable B, holding all other variables constant. This is not always possible and could lead to a problem caused by omitted variables.
Figure A-6 a. But, if Variable C has also changed, it is entirely possible that Variable C is responsible for the change in Variable B. Another problem is reverse causality. However, it is entirely possible that the change in Variable B led to the change in Variable A.
It is not always as simple as determining which variable changed first because individuals often change their behavior in response to a change in their expectations about the future.
There are two very good examples in the text that you should use in class. To discuss the omitted variable problem, point out to students that a rise in the sales of cigarette lighters is positively related to the number of individuals diagnosed with lung cancer.
To discuss reverse causality, show that an increase in minivan sales is followed by an increase in birth rates.
Economics is like a science because economists devise theories, collect data, and analyze the data in an attempt to verify or refute their theories.
In other words, economics is based on the scientific method. Figure 1 shows the production possibilities frontier for a society that produces food and clothing. Point A is an efficient point on the frontier , point B is an inefficient point inside the frontier , and point C is an infeasible point outside the frontier. Figure 1 The effects of a drought are shown in Figure 2.
The drought reduces the amount of food that can be produced, shifting the production possibilities frontier inward. Figure 2 Microeconomics is the study of how households and firms make decisions and how they interact in markets. Macroeconomics is the study of economy-wide phenomena, including inflation, unemployment, and economic growth. Many other examples are possible. Many other answers are possible.
Economic advisers to the president might disagree about a question of policy because of differences in scientific judgments or differences in values. Chapter Quick Quiz 1. Economics is a science because economists use the scientific method. Economists use theory and observation like other scientists, but they are limited in their ability to run controlled experiments.
