Описание: How much does quantity demanded change when price changes? By a lot or by a little? Elasticity can help us understand this question. This video covers determinants of elasticity such as availability of substitutes, time horizon, classification of goods, nature of goods (is it a necessity or a luxury?), and the size of the purchase relative to the consumer’s budget.
