Cement exports from the U.S. into Canada are valued at roughly $119M annually. Cement imports to the U.S. from Canada are valued at roughly $542M annually. Cement production is a highly carbon intensive process. Suppose the U.S. government is deciding whether to impose a carbon tax on the domestic (U.S.) cement production. One concern the government has is "leakage." A second concern is the potential to reduce the competitiveness of U.S. cement producers. Answer the following questions. Where applicable make sure to use a supply/demand market model to support and demonstrate your results. (a) How will a unilateral tax on domestic cement production affect the welfare of domestic consumers and producers? (b) How would the leakage problem undermine the goal of reducing global carbon emissions associated with cement production? (c) How might a border carbon adjustment tariff policy remedy the leakage problem? (d) How would a domestic producer subsidy remedy the government's anti-competitiveness concerns
