Q4. Assume demand for a good is given by P=40-0.3X, where X is the number of units of the good produced. The marginal private cost of producing the good is constant and equal to 10. Production of the good is associated with an external cost and hence marginal social cost of production is MSC=10+0.1X. If we impose a tax of 7.5 on the producer social optimum will be achieved. True/False/Uncertain. Explain.
