The United States and all other modern industrial economies experience significant swings in economic activity. In some years, most industries are booming and unemployment is low; in other years, most industries are operating well below capacity and unemployment is high. Periods of economic prosperity are typically called expansions or booms; periods of economic decline are […]| Econlib
Robert Lucas was awarded the 1995 Nobel Prize in economics “for having developed and applied the hypothesis of rational expectations, and thereby having transformed macroeconomic analysis and deepened our understanding of economic policy.” More than any other person in the period from 1970 to 2000, Robert Lucas revolutionized macroeconomic theory. His work led directly […]| Econlib
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
The term “supply-side economics” is used in two different but related ways. Some use the term to refer to the fact that production (supply) underlies consumption and living standards. In the long run, our income levels reflect our ability to produce goods and services that people value. Higher income levels and living standards cannot be […]| Econlib
The marginal tax rate is the rate on the last dollar of income earned. This is very different from the average tax rate, which is the total tax paid as a percentage of total income earned. In 2003, for example, the United States imposed a 35 percent tax on every dollar of taxable income above […]| 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
A worldwide depression struck countries with market economies at the end of the 1920s. Although the Great Depression was relatively mild in some countries, it was severe in others, particularly in the United States, where, at its nadir in 1933, 25 percent of all workers and 37 percent of all nonfarm workers were completely out […]| Econlib
The world’s population increased by 50 percent between 1900 and 1950 and by 140 percent between 1950 and 2000, and is projected by the United Nations to increase by just under 50 percent between 2000 and 2050. Of the 3.44 billion increase in the number of people between 1950 and 2000, only 8 percent was […]| Econlib
The most basic laws in economics are the law of supply and the law of demand. Indeed, almost every economic event or phenomenon is the product of the interaction of these two laws. The law of supply states that the quantity of a good supplied (i.e., the amount owners or producers offer for sale) rises […]| Econlib
