Regressive supply curve,
Definition of Regressive supply curve:
Graph curve that slopes upwards to the left of the chart, showing the unusual situation where the amount of a product (good or service) supplied decreases with the increase in its price. These curves are never found over a whole range of prices, but can occur over a part of the range such as in supply of labor where an increase in wages may result in a lower-availability of paying jobs.
