Public Goods and Externalities, Government Spending

    Public Goods and Externalities, from the Concise Encyclopedia of Economics
    Most economic arguments for government intervention are based on the idea that the marketplace cannot provide public goods or handle externalities. Public health and welfare programs, education, roads, research and development, national and domestic security, and a clean environment all have been labeled public goods.

    Public goods have two distinct aspects—"nonexcludability" and "nonrivalrous consumption." Nonexcludability means that nonpayers cannot be excluded from the benefits of the good or service. If an entrepreneur stages a fireworks show, for example, people can watch the show from their windows or backyards. Because the entrepreneur cannot charge a fee for consumption, the fireworks show may go unproduced, even if demand for the show is strong....
    Government Spending, from the Concise Encyclopedia of Economics
    In the past, government spending increased during wars and then typically took some time to fall back to its previous level. Because the effects of World War I were not totally gone by 1929, the line for the United States from 1790 to 1929 has a very slight upward slant. But in the second quarter of the twentieth century, government spending began a rapid and steady increase. While economists and political scientists have offered many theories about what determines the level of government spending, there really is no known explanation for either part of this historical record....
    Distribution of Income, from the Concise Encyclopedia of Economics
    The distribution of income is central to one of the most enduring issues in political economics. On one extreme are those who argue that all incomes should be the same, or as nearly so as possible, and that a principal function of government should be to redistribute income from the haves to the have-nots. On the other extreme are those who argue that any income redistribution by government is bad....
    Federal Budget, from the Concise Encyclopedia of Economics
    Deficit spending has been a way of life for the federal government for most years since World War II. A whole generation of elected federal officials has come and gone without ever balancing the budget. The last time that federal budget expenditures were brought into balance with revenues was in 1969, and prior to that the last time was in 1960....
    Taxation, A Preface, from the Concise Encyclopedia of Economics
    Economists specializing in public finance have long enumerated four objectives of tax policy: simplicity, efficiency, fairness, and revenue sufficiency. While these objectives are widely accepted, they often conflict, and different economists have different views of the appropriate balance among them....

    Public Schools, from the Concise Encyclopedia of Economics
    By most accounts America's schools are not performing very well. The average combined (verbal and mathematics) score on the Scholastic Aptitude Test was seventy-five points higher in 1963 than it was in 1990. A high school senior ranked at the 50th percentile on the SAT in 1990 would have ranked around the 33rd percentile in 1963. American students trail most of their international counterparts in mathematics and science achievement. Recent comparisons of industrialized countries place the United States between tenth and fifteenth in these economically vital fields. And excellence is not all that is missing. Performance among schools is quite inconsistent. Blacks score nearly two hundred points below whites on the SAT. Urban high schools, which serve disproportionately large numbers of poor families, fail to graduate nearly half of their students; high schools nationwide graduate about four-fifths of theirs....
    Electric Utility Regulation, from the Concise Encyclopedia of Economics
    Two characteristics of electric power make utilities different from most other industries. First, both high-voltage transmission and low-voltage distribution are most economically performed by a single line or a single network of lines. Because a single high-capacity line minimizes both capital costs and losses to electrical resistance per unit of power carried, transmission and distribution are natural monopolies....

    Bonds, Borrowing, and Lending, on Econlib.
    bond is a promise to pay. It is a promise to pay something in the future in exchange for receiving something today.

    Promises—that is, bonds—can be bought and sold. The buyer of a bond is a lender. The seller of a bond is a borrower. The bond buyers pay now in exchange for promises of future repayment—that is, they are lenders. The bond sellers receive money now and in exchange for their promises of future repayment—that is, they are borrowers.

    Bonds can be traded privately between individuals or in organized markets, called bond markets or credit markets.

    You may not realize it, but you buy and sell bonds all the time! Every time you lend someone a few dollars for lunch or borrow your friend's car in exchange for filling her tank, in economic terms you are buying and selling bonds. Simply remembering that bond buyers are lenders, bond sellers are borrowers, and that they are trading not pieces of paper but promises, can unlock the door to understanding both the vocabulary and the economics of a wide range of economic behavior, from private loans to interest rates to government budget deficits. It's much easier to understand borrowing and lending than abstract vocabulary like "the bond market"—even though they are the same thing—because we can by think about our own familiar experiences with borrowing and lending....

    When you use your credit cards or buy on installment, you are a borrower. In each case, someone—a bank or business owner—lends you the money by directly paying for the goods up front on your behalf. The lender later sends you a bill, at which time you are responsible to pay the principal and any accumulated interest to the lender. In economic terms, every time you use your credit card, you sell a bond—your promise to repay the credit card company in the future.

    When you deposit money in a bank, you are a lender! In economic terms, you buy the bank's bond— its commitment to repay you when you decide to use the money. The bank acts as an intermediary (a go-between) and pairs you with a borrower....

    Here's another example. When you buy a Treasury Bill, you are lending to the government. The government sells its promises to pay in organized markets each week....

    Bonds, from the Concise Encyclopedia of Economics
    Bond markets are important components of capital markets. Bonds are fixed-income financial assets--essentially IOUs that promise the holder a specified set of payments. The value of a bond, like the value of any other asset, is the present value of the income stream one expects to receive from holding the bond. This has several implications...
    Interest, from the Concise Encyclopedia of Economics
    Interest rates quoted by lenders usually include much more than "pure" interest. To persuade a lender to surrender current control of resources, the borrower will have to pay, in addition to interest, an amount that compensates the lender for any costs incurred in arranging the transaction, usually including some kind of insurance premium against the risk of default by the borrower. Someone without an established credit rating who applies for an unsecured loan will typically be required to pay "interest" at an annual rate that is several times the prevailing rate of pure interest....

    Bank Runs, from the Concise Encyclopedia of Economics
    A run on a bank occurs when a large number of depositors, fearing that their bank will be unable to repay their deposits in full and on time, try to withdraw their funds immediately. This creates a problem because banks keep only a small fraction of deposits on hand in cash; they lend out the majority of deposits to borrowers or use the funds to purchase other interest-bearing assets like government securities. When a run comes, a bank must quickly increase its liquidity to meet depositors' demands. It does so primarily by selling assets, frequently at fire-sale prices. Losses on these sales can make the bank insolvent....
    Bankruptcy, from the Concise Encyclopedia of Economics
    Bankruptcy is common in America today. Notwithstanding two decades of largely uninterrupted economic growth, the annual bankruptcy filing rate has quintupled, topping 1.5 million individuals annually. Recent years also have seen several of the largest and most expensive corporate bankruptcies in history. This confluence of skyrocketing personal bankruptcies in a period of prosperity, an increasingly expensive and dysfunctional Chapter 11 reorganization system, and the macroeconomic competitive pressures of globalization has spurred legislative efforts to reform the bankruptcy code....
    Housing, from the Concise Encyclopedia of Economics
    ... Assuming a family can spend 30 percent of its income on a mortgage, even with low 5 percent interest rates a family must earn more than $135,000 per year to afford the median-priced new home. If the above estimates are correct, regulations such as urban growth boundaries, moratoriums on building permits, environmental regulations, and other restrictions raise home prices as much as $300,000 in this county. Put another way, the portion of purchase price paid by residents of Santa Clara County due to regulation is almost enough to buy three complete homes of median value elsewhere in the United States....

    Federal deposit insurance became law for commercial banks in 1933 as part of the Glass-Steagall Act, and for S&Ls in 1934. Although a number of state governments had provided deposit insurance before 1933, most state programs had failed and all had been disbanded by then.

    For a while, the system worked well. In the 1960s and 1970s, almost all Americans got S&L financing for buying their homes. Interest rates paid on deposits at S&Ls were kept low, but millions of Americans put their money in them because deposit insurance made them an extremely safe place to invest. Starting in the 1960s, however, general interest rate levels began rising with inflation. By the 1980s, many depositors started seeking higher returns by putting their savings into money market funds and other non-bank assets. This put banks and savings and loans in a dire financial squeeze, unable to attract new deposits to cover their large portfolios of long-term loans....

Externalities occur when one person's actions affect another person's well-being and the relevant costs and benefits are not reflected in market prices. A positive externality arises when my neighbors benefit from my cleaning up my yard. If I cannot charge them for these benefits, I will not clean the yard as often as they would like. (Note that the free-rider problem and positive externalities are two sides of the same coin.) A negative externality arises when one person's actions harm another. When polluting, factory owners may not consider the costs that pollution imposes on others....
What is a public good? Defense, from the Concise Encyclopedia of Economics
National defense is a public good. That means two things. First, consumption of the good by one person does not reduce the amount available for others to consume. Thus, all people in a nation must "consume" the same amount of national defense (the defense policy established by the government). Second, the benefits a person derives from a public good do not depend on how much that person contributes toward providing it. Everyone benefits, perhaps in differing amounts, from national defense, including those who do not pay taxes. Once the government organizes the resources for national defense, it necessarily defends all residents against foreign aggressors....
Market-clearing vs. sticky prices: New Keynesian Economics, from the Concise Encyclopedia of Economics
The primary disagreement between new classical and new Keynesian economists is over how quickly wages and prices adjust. New classical economists build their macroeconomic theories on the assumption that wages and prices are flexible. They believe that prices "clear" markets—balance supply and demand—by adjusting quickly. New Keynesian economists, however, believe that market-clearing models cannot explain short-run economic fluctuations, and so they advocate models with "sticky" wages and prices. New Keynesian theories rely on this stickiness of wages and prices to explain why involuntary unemployment exists and why monetary policy has such a strong influence on economic activity....
Markets can fail if there are no property rights and negotiation is costly. The Coase Theorem: Ronald H. Coase, biography from the Concise Encyclopedia of Economics
"The Problem of Social Cost," Coase's other widely cited article (661 citations between 1966 and 1980), was even more path-breaking. Indeed, it gave rise to the field called law and economics. Economists b.c. (Before Coase) of virtually all political persuasions had accepted British economist Arthur Pigou's idea that if, say, a cattle rancher's cows destroy his neighboring farmer's crops, the government should stop the rancher from letting his cattle roam free or should at least tax him for doing so. Otherwise, believed economists, the cattle would continue to destroy crops because the rancher would have no incentive to stop them.

But Coase challenged the accepted view. He pointed out that if the rancher had no legal liability for destroying the farmer's crops, and if transaction costs were zero, the farmer could come to a mutually beneficial agreement with the rancher under which the farmer paid the rancher to cut back on his herd of cattle. This would happen, argued Coase, if the damage from additional cattle exceeded the rancher's net returns on these cattle. If for example, the rancher's net return on a steer was two dollars, then the rancher would accept some amount over two dollars to give up the additional steer. If the steer was doing three dollars' worth of harm to the crops, then the farmer would be willing to pay the rancher up to three dollars to get rid of the steer. A mutually beneficial bargain would be struck....

Balance of Payments, Imports, Exports, Mercantilism, Mercantile System, Foreign Trade, or The Wedding Gown

Definitions and Basics
Balance of Payments, from the Concise Encyclopedia of Economics
The balance of payments accounts of a country record the payments and receipts of the residents of the country in their transactions with residents of other countries. If all transactions are included, the payments and receipts of each country are, and must be, equal. Any apparent inequality simply leaves one country acquiring assets in the others. For example, if Americans buy automobiles from Japan, and have no other transactions with Japan, the Japanese must end up holding dollars, which they may hold in the form of bank deposits in the United States or in some other U.S. investment. The payments of Americans to Japan for automobiles are balanced by the payments of Japanese to U.S. individuals and institutions, including banks, for the acquisition of dollar assets. Put another way, Japan sold the United States automobiles, and the United States sold Japan dollars or dollar-denominated assets such as Treasury bills and New York office buildings....

Although the totals of payments and receipts are necessarily equal, there will be inequalities—excesses of payments or receipts, called deficits or surpluses—in particular kinds of transactions. Thus, there can be a deficit or surplus in any of the following: merchandise trade (goods), services trade, foreign investment income, unilateral transfers (foreign aid), private investment, the flow of gold and money between central banks and treasuries, or any combination of these or other international transactions.
Imports, from AmosWEB's Economics Gloss*arama.
IMPORTS: Goods and services produced by the foreign sector and purchased by the domestic economy. In other words, imports are goods purchased from other countries. The United States, for example, buys a lot of the stuff produced within the boundaries of other countries, including bananas, coffee, cars, chocolate, computers, and, well, a lot of other products. Imports, together with exports, are the essence of foreign trade--goods and services that are traded among the citizens of different nations. Imports and exports are frequently combined into a single term, net exports (exports minus imports)....
Exports, from AmosWEB's Economics Gloss*arama.
EXPORTS: The sale of goods to a foreign country. The United States, for example, sells a lot of the stuff produced within our boundaries to other countries, including wheat, beef, cars, furniture, and, well, almost every variety of product you care to name. In general, domestic producers (and their workers) are elated with the prospect of selling their goods to foreign countries--leading to more buyers, a higher price, and more profit. The higher price, however, is bad for domestic consumers. In that domestic consumers tend to have far less political clout than producers, very few criticisms of exports can be heard....
Balance of Trade, from AmosWEB's Economics Gloss*arama.
BALANCE OF TRADE: The difference between the value of goods and services exported out of a country and the value of goods and services imported into the country. The balance of trade is the official term for net exports that makes up the balance of payments. The balance of trade can be a "favorable" surplus (exports exceed imports) or an "unfavorable" deficit (imports exceed exports). The official balance of trade is separated into the balance of merchandise trade for tangible goods and the balance of services....

A balance of trade surplus is most favorable to domestic producers responsible for the exports. However, this is also likely to be unfavorable to domestic consumers of the exports who pay higher prices.

Alternatively, a balance of trade deficit is most unfavorable to domestic producers in competition with the imports, but it can also be favorable to domestic consumers of the exports who pay lower prices....


In the News and Examples
Popular myth: Aren't imports bad? Aren't exports good? Isn't a trade deficit a bad thing? The very word "deficit" sounds bad! Economic reality: An excess of imports over exports merely sends dollar bills overseas while bringing real goods and services into the country for immediate use. If foreigners want to hold onto those dollars, while we get to put their goods to immediate use benefiting our consumers and creating new investment for our industries, then we get an even better deal! Prohibiting trade severely limits what you can accomplish.


    • Don Boudreaux on the Economics of "Buy Local". Podcast at EconTalk, April 16, 2007.
Proponents of buying local argue that it is better to buy from the local hardware store owner and nearby farmer than from the Big Box chain store or the grocery store headquartered out of town because the money from the purchase is more likely to "stay in the local economy." Don Boudreaux of George Mason University talks with EconTalk host Russ Roberts about the economics of this idea. Is it better to buy local than from a seller based out of town? Is it better to buy American than to buy foreign products? Does the money matter?

    • The Balance of Trade, by Frédéric Bastiat. Chapter 6 in Economic Sophisms, first published 1845 in France.
There is still a further conclusion to be drawn from all this, namely, that, according to the theory of the balance of trade, France has a quite simple means of doubling her capital at any moment. It suffices merely to pass its products through the customhouse, and then throw them into the sea. In that case the exports will equal the amount of her capital; imports will be nonexistent and even impossible, and we shall gain all that the ocean has swallowed up.

Mercantilism, from the Concise Encyclopedia of Economics
Mercantilism is economic nationalism for the purpose of building a wealthy and powerful state. Adam Smith coined the term "mercantile system" to describe the system of political economy that sought to enrich the country by restraining imports and encouraging exports. This system dominated western European economic thought and policies from the sixteenth to the late eighteenth century. The goal of these policies was, supposedly, to achieve a "favorable" balance of trade that would bring gold and silver into the country. In contrast to the agricultural system of the physiocrats, or the laissez-faire of the nineteenth and early twentieth centuries, the mercantile system served the interests of merchants and producers such as the British East India Company, whose activities were protected or encouraged by the state....

The theory of the balance of trade and the consequences which were drawn therefrom constitute what is called the mercantile system, because the whole of this system tends to consider foreign commerce as the most productive branch of a nation's labor. It is supposed that a nation can sell more than it buys, in a way to ruin neighboring nations by absorbing their precious metals by the greatest possible exportation and the least possible importation. This false theory still prevails in the minds of the masses, and still serves as a rule for many administrations and governments; it forms the basis of the economic ideas of all the writers of the eighteenth century, who did not belong to the physiocratic school or to that of Adam Smith; it is still appealed to in our days by statesmen, and by all those who, by conviction or for financial considerations, defend prohibition, high tariffs and custom impediments....

Assumption of full employment


Loan able fund theory is based on the unrealistic assumption of full employment but the Keynesian theory of interest is applicable both even in full employment and in less than fall employment conditions.
Profit
            There are four factors of production. They are Land, labor, Capital and organization, which is also called entrepreneur.
            According to the pricing theory of factors of production or theory of distribution, all the factors of production are paid according to their contribution on the total national product or equal to their marginal productivity. In this regard, rent, wages & interest respectively are paid as the reward to the factors of production Land, Labor & capital. Alike mentioned factors of production, entrepreneur also gets remuneration which is termed as profit. Hence, profit is the reward of entrepreneur.
            Entrepreneur is the active factor of production. An entrepreneur collects the factors of production Land, Labor & capital in one place and uses them skillfully in the process of production. In this regard, entrepreneur has to perform entrepreneurial functions such as organizing & co-coordinating the other factors. So some economists argue that entrepreneur earns profit for his performing this function.
            A part of the confusion in the theory of profit is due to the lack of agreement among economists about the true or proper function of the entrepreneur.
            Some economists have described the use preneur as performing joint and, in separation functions of final risk bearing and final decision-making.
            Alfred Marshall gave the first systematic explanation of the nature of profit in terms of demand and supply of entrepreneurs.
            Walker looked upon profit as the reward of the entrepreneur with a superior ability than others. Hawley ascribed it to the entrepreneur's risk- taking, the greater the risk undertaken, and the larger the profit according to him.
            Mrs. Joan Robinson, Prof. Chamber line and Mr. Kalecki have associated profits with the imperfect competition and monopoly. Monopoly profits arise became a monopolist is able to restrict output and keep the price of his product much above the average cost of production.
            Though these are various views of economists on the meaning of profit. Profit is defined as the residual income rescind after paying all the expenses in curved in the process of production. Profits can be divided into two parts cross profit Net profit.
Dynamic theory of profit
            An American economist J.B. Clark propounded the dynamic theory of profit in 1900. According to him, profit is the difference between the selling price and the cost of production of good Commodity. But profit is the result of dynamic changes, which mean change in the condition of demand and supply. Now, in competitive long run equilibrium, as the price equals to the average cost of production, an entrepreneur cannot earn pure profit. In this condition, a normal profit is included in the cost of production. But this normal profit is called a wage received as a reward for supervision and management of an entrepreneur by Clark.
            To know the state of dynamic changes Clark has divided the whole economy into two parts. (i) Static economy (ii) Dynamic economy.
(i)   Static economy
            This is the stationary state of economy where no changes in the condition of demand & supply are made. So, all the factors affecting demand and supply are assumed to be constant in such a economy. There is no uncertainty & risk at all in these types of economy. As all the factors are constant, all the firms including industry are constant in such a situation. Hence, the cost of production of good is equal to the price. This creates no profits to the entrepreneur in static economy. According to Prof. Clark, the entrepreneur gets only wages for his labor and interest on his capital in such a static economy.
            But due to same reasons, if price is more than the cost of production, then the entrepreneur may earn profit, which will be only frictional profit and a kind of short-term phenomenon. But after some time, due to perfect competition in the economy, this profit will be disappeared.
(ii)  Dynamic economy
            The world is changing day by day. So the static economy is only an imaginary concept. So, there is change in the factors affecting demand for and supply of goods. Due to these changes, the state of equilibrium also after in the economy in this condition, if entrepreneur can make the situation favorable he gets profit. According to Clark, there are five kinds of changes which creates profits
