Learning curve in psychology and economics The first person to describe the learning curve was Hermann Ebbinghaus in 1885. He found that the time required to memorize a nonsense word increased sharply as the number of syllables increased.[1] Psychologist‚ Arthur Bills gave a more detailed description of learning curves in 1934. He also discussed the properties of different types of learning curves‚ such as negative acceleration‚ positive acceleration‚ plateaus‚ and ogive curves.[2] In 1936‚ Theodore

THE PHILLIPS CURVE The short-run relationship between inflation and unemployment is often called the Phillips curve. In 1958‚ economist A. W.

The Laffer curve‚ named after the economist Arthur Laffer‚ is a curve that demonstrates the trade-off between tax-rates and tax-revenues (Wanniski 1978). It is used to illustrate the concept of taxable income elasticity‚ the idea that a government can maximise the revenue by setting the tax rates at an optimum point. This curve can be traced back as far as 1844 to a French economist Jules Dupit who in 1844 found similar effects as Laffer did (Laffer 2004). Dupit also saw tax revenues rising from

Limitations of the Lorenz Curve The Lorenz Curve illustrates the degree of equality (or inequality) of distribution of income in an economy. It plots the cumulative percentage of income received by cumulative shares of the population and includes a straight line to illustrate perfect income equality. Thus‚ the closer the Lorenz curve is to the straight line‚ the greater the equality in income distribution‚ while‚ the further away it is from the straight line‚ the more unequal the distribution
