Define or explain the following concept:
Unitary Elastic Demand
उत्तर
Unitary elastic demand implies that a change in the price of a commodity leads to a proportionate change in the quantity demanded of that commodity. For instance, if the demand for Good X is unitary elastic, a 50% increase in the price of Good X will lead to a 50% decline in the quantity demanded of Good X. In this case, Ed = 1.
