Fundamentally, the economics of pollution control attempts to balance the cost of pollution clean-up with the damage cost to the environment at the margin. With this in mind, explain what decision should be undertaken with respect to the level of pollution under each of the following situations:

a) \(\mathrm{MCC}>\mathrm{MDC}\)

b) \(\mathrm{MCC}<\mathrm{MDC}\)

c) \(\mathrm{MCC}=\mathrm{MDC}\)
