The price elasticity of demand for insulin is about 0.20 -- that is, demand is very inelastic, because diabetics need insulin. On the other hand, the price elasticity of supply for insulin is 1.8 as production is easy but pharmaceutical companies want to maintain a presence in the insulin market. If the government decides to impose a $20 excise tax on pharmaceutical companies for each vial of insulin, which of the following likely best describes how much of the $20 tax will be born by consumers and how much will be born by firms? O a. Consumers will bear $8 of the tax, while firms will bear $12 of the tax. O b. Consumers will bear $20 of the tax, while firms will bear $0 of the tax. c. Consumers will bear $18 of the tax, while firms will bear $2 of the tax. O d. Consumers will bear $10 of the tax, while firms will bear $10 of the tax. Ore. Consumers will bear $0 of the tax, while firms will bear $20 of the tax
