Economic Glossary

Lagging indicators
Old news. Some economic statistics move weeks or months after changes in the BUSINESS CYCLE or INFLATION. They may not be a reliable guide to the current state of an economy or its future path. Contrast with LEADING INDICATORS

Nafta
Short for North American Free-Trade Agreement. In 1993, the United States, Mexico and Canada agreed to lower the barriers to trade among the three economies. The formation of this regional TRADE AREA was opposed by many politicians in all three countries. In the United States and Canada, in particular, there were fears that NAFTA would result in domestic job losses to cheaper locations in Mexico. In the early years of the agreement, however, most studies found that the economic gains far outweighed any costs.

Nash equilibrium
An important concept in GAME THEORY, a Nash equilibrium occurs when each player is pursuing their best possible strategy in the full knowledge of the strategies of all other players. Once a Nash equilibrium is reached, nobody has any incentive to change their strategy. It is named after John Nash, a mathematician and Nobel prize-winning economist

Regressive tax
A tax that takes a smaller proportion of INCOME as the taxpayer’s income rises, for example, a fixed-rate vehicle tax that eats up a much larger slice of a poor person’s income than a rich person’s income. This goes against the principle of VERTICAL EQUITY, which many people think should be at the heart of any fair tax system.
