HUMAN DEVELOPMENT INDEX: A summary composite index that measures a country's average achievements in three basic aspects of human development: longevity, knowledge, and a decent standard of living. Longevity is measured by life expectancy at birth; knowledge is measured by a combination of the adult literacy rate and the combined primary, secondary, and tertiary gross enrollment ratio; and standard of living is measured by GDP per capita. The Human Development Index (HDI), reported in the Human Development Report of the United Nations, is an indication of where a country is development wise. The index can take value between 0 and 1. Countries with an index over 0.800 are part of the High Human Development group. Between 0.500 and 0.800, countries are part of the Medium Human Development group and below 0.500 they are part of the Low Human Development group.

PERFECT COMPETITION, REALISM

Perfect competition is an idealized market structure that does NOT exist in the real world. While some real world industries might come relatively close to one or two of the four key characteristics of perfect competition, none matches all four sufficiently that they can be declared PERFECTLY competitively. Some industries come close on the large number of small firms and the identical product characteristics. A few industries have relatively good, although not perfect, information about prices and technology. However, almost all industries fall far short of the perfect mobility characteristics.
