Determinants of Elasticity
answer
1. Number of substitutes available
2. The cost of proportion of one's budget
3. Whether a good is a necessity or a luxury
4. The period to respond to changes in price
Elastic goods have many substitutes, are a large portion of one's budget, tend to be luxury goods, and/or have a long time horizon for responses
