Following the end of the Allied occupation of Japan, real increases in GNP averaged 9.6 percent from 1952 to 1971. From 1972 to 1991, growth remained strong but less dramatic, averaging 4 percent per year. The rest of the 1990s and early 2000s have been a different story. From 1991 to 2003, real economic growth […]| Econlib
In 1974 the general public got a graphic illustration of the “tragedy of the commons” in satellite photos of the earth. Pictures of northern Africa showed an irregular dark patch 390 square miles in area. Ground-level investigation revealed a fenced area inside of which there was plenty of grass. Outside, the ground cover had been […]| Econlib
Intellectual property is normally defined as the set of products protected under laws associated with copyright, patent, trademark, industrial design, and trade secrets. The U.S. Constitution expressly allows for intellectual property protection, albeit for a limited time, in the form of protection of “writings and discoveries” in order to promote “science and useful arts.” This […]| Econlib
Corporations are easier to create than to understand. Because corporations arose as an alternative to partnerships, they can best be understood by comparing these competing organizational structures. The presumption of partnership is that the investors will directly manage their own money rather than entrusting that task to others. Partners are “mutual agents,” meaning that each […]| Econlib
To economists, efficiency is a relationship between ends and means. When we call a situation inefficient, we are claiming that we could achieve the desired ends with less means, or that the means employed could produce more of the ends desired. “Less” and “more” in this context necessarily refer to less and more value. Thus, […]| Econlib
The price of a share of stock, like that of any other financial asset, equals the present value of the sum of the expected dividends or other cash payments to the shareholders, where future payments are discounted by the interest rate and risks involved. Most of the cash payments to stockholders arise from dividends, which […]| Econlib
To most people, capital means a bank account, a hundred shares of IBM stock, assembly lines, or steel plants in the Chicago area. These are all forms of capital in the sense that they are assets that yield income and other useful outputs over long periods of time. But such tangible forms of capital are […]| Econlib
Few economic indicators are of more concern to Americans than unemployment statistics. Reports that unemployment rates are dropping make us happy; reports to the contrary make us anxious. But just what do unemployment figures tell us? Are they reliable measures? What influences joblessness? How Is Unemployment Defined and Measured? Each month, the federal government’s Bureau […]| Econlib
Compound Rates of Growth In the modern version of an old legend, an investment banker asks to be paid by placing one penny on the first square of a chessboard, two pennies on the second square, four on the third, etc. If the banker had asked that only the white squares be used, the initial […]| Econlib
When economists refer to the “opportunity cost” of a resource, they mean the value of the next-highest-valued alternative use of that resource. If, for example, you spend time and money going to a movie, you cannot spend that time at home reading a book, and you cannot spend the money on something else. If your […]| Econlib
The rate of interest measures the percentage reward a lender receives for deferring the consumption of resources until a future date. Correspondingly, it measures the price a borrower pays to have resources now. Suppose I have $100 today that I am willing to lend for one year at an annual interest rate of 5 percent. […]| Econlib
Businesses complain about regulation incessantly, but many citizens, consumer advocates, and nongovernmental organizations (NGOs) think it absolutely necessary to protect the public interest. What is regulation? Why do we have it? How has it changed? This article briefly provides some answers, concentrating on experience with regulation in the United States. Regulation consists of requirements the […]| Econlib
Investment is one of the most important variables in economics. On its back, humans have ridden from caves to skyscrapers. Its surges and collapses are still a primary cause of recessions. Indeed, as can be seen in Figure 1, investment has dropped sharply during almost every postwar U.S. recession. As the graph suggests, one cannot […]| Econlib
If any twentieth-century economist was a Renaissance man, it was Friedrich Hayek. He made fundamental contributions in political theory, psychology, and economics. In a field in which the relevance of ideas often is eclipsed by expansions on an initial theory, many of his contributions are so remarkable that people still read them more than fifty […]| Econlib
