As applied to consumers, the quantity of one commodity or service that a given consumer feels he must acquire to compensate him exactly for the loss of one unit of some other commodity or service. When applied to money, the marginal rate of substitution is the price that a given consumer may be willing to pay for a specified quantity of some commodity or service.  3, record 1, English, - marginal%20rate%20of%20substitution

An "indifference curve" or "equal-utility contour" depicts the points of equally desirable consumption. The indifference contour is usually drawn convex from below, in accordance with the empirical law of diminishing relative marginal utilities (or of substitution ratios).  2, record 2, English, - indifference%20curve

Expresión gráfica en un sistema de coordenadas, que permite el trazado de líneas que expresan para cada uno de sus puntos una combinación concreta de consumo de dos bienes o grupos de bienes, que al consumidor le resulta indiferente con las situaciones expresadas por los demás puntos de la línea. Las curvas de indiferencia, a medida que se alejan del origen de las coordenadas, implican mayores consumos y, por ello, en principio, niveles crecientes de satisfacción.  1, record 2, Spanish, - curva%20de%20indiferencia

By the arithmetic slope of the indifference curve, we mean this : To find the slope of the curve at, say, point B, take a ruler and place it so that it is just tangent to the curve at B--it touches the curve, but does not cross it either above or below B. Mark the points at which the ruler's edge crosses the two axes. The slope is the ratio of the distance cut off on the vertical axis to the distance cut off on the horizontal axis.  1, record 5, English, - arithmetic%20slope%20of%20the%20indifference%20curve
