Problem
Consider the tax on study drugs from before. Let's get real. The average student buys two buckets of Adderall per semester for $10 each, so P= 10 and Q=2. The dean finally applies a $1 tax. The elasticity of demand for cocaine at CWRU is -0.5 and the elasticity of supply is 0.7. What is the DWL per student caused by the tax?
