Measuring prices and their rate of change accurately is central to almost every economic issue, from the conduct of monetary policy to measuring economic progress (see economic growth) over time and across countries to the cost and structure of indexed government spending programs and taxes. Most of us are familiar with the prices of many […]| Econlib
How do economists measure income inequality, and how has it changed over time? This entry explores these questions and the cause of income inequality,| 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
The U.S. welfare system would be an unlikely model for anyone designing a welfare system from scratch. The dozens of programs that make up the “system” have different (sometimes competing) goals, inconsistent rules, and over-lapping groups of beneficiaries. Responsibility for administering the various programs is spread throughout the executive branch of the federal government and […]| Econlib
Rent seeking is one of the most important insights in the last fifty years of economics and, unfortunately, one of the most inappropriately labeled. Gordon Tullock originated the idea in 1967, and Anne Krueger introduced the label in 1974. The idea is simple but powerful. People are said to seek rents when they try to […]| Econlib
The Birth of the “Blues” In the 1930s and 1940s, a competitive market for health insurance developed in many places in the United States. Typically, premiums tended to reflect risks, and insurers aggressively monitored claims to keep costs down and prevent abuses. Following World War II, however, the market changed radically. Hospitals had created Blue […]| Econlib
Is Health Care Different? Health care is different from other goods and services: the health care product is ill-defined, the outcome of care is uncertain, large segments of the industry are dominated by nonprofit providers, and payments are made by third parties such as the government and private insurers. Many of these factors are present […]| 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
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
In recent years, taxation has been one of the most prominent and controversial topics in economic policy. Taxation has been a principal issue in every presidential election since 1980—with a large tax cut as a winning issue in 1980, a pledge of “Read my lips: no new taxes” in the 1988 campaign, and a statement […]| Econlib
Saving means different things to different people. To some, it means putting money in the bank. To others, it means buying stocks or contributing to a pension plan. But to economists, saving means only one thing—consuming less out of a given amount of resources in the present in order to consume more in the future. […]| Econlib
Insurance plays a central role in the functioning of modern economies. Life insurance offers protection against the economic impact of an untimely death; health insurance covers the sometimes extraordinary costs of medical care; and bank deposits are insured by the federal government (see financial regulation). In each case, the insured pays a small premium in […]| Econlib
The law of unintended consequences, often cited but rarely defined, is that actions of people—and especially of government—always have effects that are unanticipated or unintended. Economists and other social scientists have heeded its power for centuries; for just as long, politicians and popular opinion have largely ignored it. The concept of unintended consequences is one […]| Econlib
