WELCOME TO ECONOMICS!
You're taking a course in Economics, and this is the text. Congratulations! Though you probably haven't thought seriously about it, consider for a moment the problems solved by the economic system. You now have this book. Yet, none of the thousands of people, involved in creating this textbook ,whose special skills included making the paper and the ink, authoring, designing, printing, binding, and distributing the book -- knew everything required to make and distribute a book.
In fact, no one person or agency planned it all with the objective of producing this book for you. Indeed, none of them knew exactly who, if anyone, would be the purchaser. Nevertheless, here it is. Everyday, an incredibly wide range of goods and services are available to you. How are people motivated and coordinated to accomplish that in a decentralized economy in which the specific final products and users aren't known?
And, why, in that process, do some people earn
more than others? How does it happen that no one need understand how and
most probably don¡¦t care -- except for a few like you, which is
undoubtedly a reason you're learning Economics.
Motivating and underlying all behavior is the inevitable presence of SCARCITY.
¡§Scarcity¡¨ means your wants and desires exceed what is available.
Ever since the fiasco in the Garden of Eden, most of what you enjoy is
acquired by your efforts, accompanied by strain, sweat, and anxiety. And,
no matter how successful your efforts, you want even more.
We want more too. Two apparent devils restrict what you can have -- first, the limited amounts of goods, and second, the rest of us who want them too. You and the remainder of us want more than there is any prospect of ever achieving. One of the authors wants membership in the Augusta National Golf Club, better golfing talent, a second home at Mauna Kea, more scientific knowledge and expertise in mathematics, more research for curing heart disease and cancer, finer art objects, and a private plane. The other wants a third car, better friends, a 6-foot digital TV with a wall-to-wall sound system, an 80 foot yacht, and a villa in France ... for starters. Everyone, rich folk too, live in a state of scarcity, if not poverty.
And it's not because society produces the "wrong"
things (cosmetics, beer, pop-jazz, TV games) instead of the "right" things
(museums, symphony orchestras, art). That contention reveals merely different,
not "right" or "wrong", tastes. Scarcity is a fact for all living objects,
people, animals, plants and even germs.
Self-interest, as the concept is used in Economics,
means you want more power to control resources, whether for your own or
for someone else's benefit. You may act as a "Good Samaritan" in emergencies.
Economic analysis recognizes that charity is present, though not a motive
or objective in market transactions, however much it occurs elsewhere.
People who say they are seeking to serve the ¡§public interest¡¨, act also
with their own personal interest in mind. Neither extreme -- total narrow
exclusive self-interest or total altruism -- is the presumption of economic
analysis, although both extremes and most everything in between can be
understood with that analysis.
Goods: Economic or Free
A "good", as that word is used in Economics, is anything of which more is wanted -- milk, candy, shoes, gasoline, etc. It includes also services by doctors, painters, singers, athletes. The word, "goods", means services as well as physical things. Fresh chicken eggs are more plentiful than stale eggs; but fresh eggs are scarce. Fresh eggs are goods; stale eggs are not. In economic terms, fresh eggs are economic goods, the term we use to describe any good for which more is desired than is available.
If a good, however desirable, is so abundant that
no one wants more of it, it is a
" free¡¨ good. But examples are not easy to find. The classic case of a free good, to most of us most of the time, is air: we simply inhale, and there it is, without our sacrificing anything to obtain it. However, air is an economic good to the astronaut and the deep-sea diver and so is fresh air to the city resident on a smoggy day. Caution: "free good" does not mean something for which a zero price is charged, like "free education", "freeways", "free public parks" "free libraries" and "free beaches".
Those "zero-price" goods are scarce (economic) goods. Charging a zero-price does not convert an economic good into a free good. As we will see later, distributing goods for "free" (at a zero price) paradoxically makes their scarcity seem even greater. Hereafter, the one word "good" will always mean an "economic" (scarce) good. If we mean "free good" we'll write "free good".
Admittedly, the term "good" creates a psychological
bias suggesting that "goods" are necessarily good, and
perhaps even good for you. In Economics, however, "goods" are whatever
a person wants, no matter why. Your notion of what is proper may differ
from other people's. Maybe you think cigarettes are not "goods" and people
would be better off without them. Nevertheless, as long as someone thinks
they are desirable and wants more -- that makes them "goods".
Scarcity's inevitable companion is competition
with other people for "more". Never presume it is absent, unless you enjoy
fantasies, for which the movies are more effective. According to a master
competitor, the golfer Arnold Palmer, "If you aren't competing, you're
dead!" To which we add, "If you aren't dead, you must be competing." How?
Consider a few.
Violence is a respected common mode of competition. Alexander, Caesar, Napoleon, Ieyasu, Eisenhower, Lenin and Mao were highly respected and revered. To be sure, had Caesar merely roughed up only a few Romans he would have been crucified. Had Lenin been defeated, he would have been liquidated on the spot. If violence is attempted on a large enough (e.g. national) scale, the perpetrators are condemned only if they fail.
The power of violence is the jealously guarded near-monopoly of a "government"-- by definition of what a government is. "Near-monopoly" because, within a nation, it is often used byindividuals in street demonstrations for access to political power.
A wealthy nation is more likely to be attacked---unless
the potential aggressors know it is willing and able to defend itself and
impose severe losses on the aggressor. The Iraqi government in 1991 attempted
to confiscate wealth from Kuwait, butwas rebuffed by the cooperation of
other nations. Some years earlier, the poorer North Koreans attacked the
South Koreans, but they also were rebuffed by the aid of richer countries
that had taken the precaution to have sufficient defensive armor. The early
Mongols and Tartars lived by raiding productive, but
less defended, communities. Europeans invaded the Southeastern Asiatic
regions to expropriate wealth from the less ably defended areas. And similar
events occurred in the migration to the Western hemisphere.
Allocations by Authorities
Consider a hypothetical university -- possibly yours -- which has 5,000 students and only 2,000 parking spaces. On the assumption that most students desire a parking space, it has a rationing problem: in one way or another, the spaces must be allocated among competitors for the space. Who gets a parking space and who doesn¡¦t? There are alternative ways to assign them.
First Come, First Served
They could be allocated on a first-come, first-served basis. Though the money price would be zero, a competitive cost would be incurred in getting to the campus before dawn in an effort to get a space. Costs need not be in money payments. A zero price does not make something free.
The costly scramble to be earlier for a space
could be avoided by prior assignment of the spaces to the most "deserving"
or "needy". Professors will, of course, get space. The committee dispensing
privileges would say, "Who are the most deserving, most needy ones?" There
is almost no limit to the ingenuity of dispensing committees in rationalizing
their favors. Among the criteria may be: distance from campus, age, health,
senior status, family size, major of student, grades, etc. But one question
leads to another. For example, should those awarded rights to a parking
space be allowed to sell the rights to others?
Competitive Cooperation By Exchanges
The primary focus of economic analysis is on (a) competition in exchange of rights to services and goods and on (b) cooperation in creating wealth.
Competition by offers of exchange is also a form of cooperation. "I'll do this for you if you'll do that for me -- at better terms than someone else." In a private property economy, an offer of exchange of property rights is a dominant form of competitively controlled cooperation. Let Adam Smith, the 18th century Scot, author of the first systematic and classic treatise on economics, "An Inquiry Into the Nature and Causes of the Wealth of Nations" comment on why it is powerful:
"Man has almost constant occasion for the help of his brethren, and it is in vain for him to expect it from their benevolence only. He will be more likely to prevail if he can interest their self-love in his favor, and show them that it is for their own advantage to do for him what he requires of them.
... Give me that which I want, you shall have
this which you want. ... It is not from the benevolence of the butcher,
the brewer, or the baker, that we expect our dinner, but their regard of
their own interest. We address ourselves not to their humanity but to their
self-love, and never talk to them of our own necessities but of their advantages."
Jungle or Civilized Competition
You may have heard "Competition in the free enterprise,
private property economy promotes anti-social, jungle-like behavior, socially
irresponsible behavior, and it increases the inequality of incomes." There
is a strong case to the contrary. A memorable proposition is that in all
economic systems -- capitalist, communist, socialist, ecclesiastic, or
whatever -- scarcity is inevitable and so competition, and inequality are
inescapable. The forms of competition and their extent are affected by
the kind of economic system in a society. The resulting type of competition
affects the kind of culture and behavior of the public. It appears that
the forms of competition that are less conducive to greater production
and "civilized" behavior are less likely to be tolerated.
All competition and choice is discriminatory.
Choice is merely another name for discrimination
... to rank alternatives according to some attribute. It is not discrimination
that is condemned, but "invidious" discrimination -- which is discrimination
by whatever criteria enough people consider undesirable -- such as religion,
nationality and gender. But some forms are more conducive to production
and civility in human relations, as we¡¦ll see later.
At the same time people compete, they cooperate
with each other -- in the market, in the family, in firms and in governments.
We cooperate to make the "pie" larger, we compete over how much of the
pie each of us gets. Any effective combination of cooperation and competition
requires a control of the permissible types of competition so as to not
obstruct cooperation. If people could be trusted to work and cooperate
as they promise, life would be unimaginably different.
Procedure: Analyzing, Not Surveying
This text is not a guided tour through the economy with our running commentary and opinions. We assume you want to understand the causes and consequences of economic events in the economy in which you live and will work. For that you must have a working familiarity with the basic concepts and principles of economics. We emphasize "working familiarity", because that means both a knowledge of the principles and also an ability to apply them. Therefore, this textbook presents validated principles of economics, along with illustrative applications. The examples and applications will increase your familiarity with the principles and your ability to apply them.
Our intent is to make your study of Economics interesting and enjoyable. But, we promise one possibly unanticipated result: you'll be brain-washed -- in the good sense of removing fallacious and erroneous beliefs. We predict you¡¦ll begin to believe that a vast majority of what people popularly believe about economic events is wrong. A few examples of errors are:
price controls prevent higher costs to consumers;
reducing unemployment requires creating more
larger incomes for some people require smaller
incomes for others;
free, or low, tuition reduces costs to students;
unemployment is wasteful;
stockbrokers and investment advisors predict better
than throwing a dart at a list of stocks;
international trade deficits are bad and surpluses
inflation is caused by government deficits;
government budget deficits reduce saving and raise
new taxes are borne by the consumer of the taxed
employers pay for "employer provided insurance";
tax-exempt bonds avoid taxes:
minimum wages help unskilled and minorities;
housing developers drive up the price of land;
foreign imports reduce domestic jobs;
"equal pay for equal work" aids women, minorities
and the young;
very low unemployment causes inflation;
the Federal Reserve Board controls the rate of
Fortunately, societies have progressed despite
almost universal ignorance of economic principles. For example, the
United States economy, over more than two centuries, has generally performed
very well, yielding a growth and prosperity which is embarrassingly conspicuous
in world history. And, the socialist collapse in Soviet Russia was not
the result of a sudden awareness of economic principles.
Instead, tough, unavoidable experience showed its weaknesses and motivated
Organization of This Book
This text has, roughly, four main groups of chapters or zones of concentration. (a) The first group focuses on principles, explaining the operations of markets in a decentralized economy in which you will be spending and investing your income and wealth. (b) The second group pertains to firms in which you, your spouse, or both, will earn incomes. (c) A third group concentrates fluctuations in aggregate, nationwide incomes -- recessions -- that will affect your earnings and wealth. (d) The fourth group attends to governments in affecting economic activity within the nation and across national boundaries.
As an aid for your learning, we recommend a visit to your college library (the educational and romantic heart of your campus) to get acquainted with the U.S. Statistical Abstract. Published by the U.S. Department of Commerce, it¡¦s a compendium of facts and measures of population, incomes, commerce, finance, government, international trade and related matters. Browsing through it will give perspective and facts about the size of the economy. Another good source of data about the economy is the U.S. Department of Commerce¡¦s monthly ¡§Survey of Current Business¡¨. And you¡¦ll find the Monthly Labor Review, published by the U.S. Department of Labor, contains interesting information about wages and working conditions.
Finally, a word of assurance: Economics really
is easy. Some say it's just common sense, which, as you have been reminded
often, is uncommon. The most frequent source of failure and confusion is
not the difficulty of learning and applying the principles. Instead, forgetting
to apply them is the trouble. Always, always remember and be aware of them
-- as alertly and fully as you heed the law of gravity, because economic
principles are more powerful and accurate. The law of
gravity says that if you put a $20 bill on a table, it will stay there.
Economics says it will quickly disappear!
