Lecture Plan - Trade Tariffs and Welfare

Estimated time - 1.30 minutes


To look at examples of the effects of trade creation/diversion

To explore the similarities of import quotas and restrictive licensing

to derive appropriate policy steps from this analysis

to show how the analysis in terms of macro institutions like the GATT and the WTO.

Learning objectives

Students should understand what a tariff and a deadweight loss is, be able to compute the 'before and after' effects of each type of tariff and quota imposition, and be able to argue for and against a policy on the grounds of free trade theory.


Last week we saw the differences between trade creation, trade destruction, and the welfare effects of both. We finished the history of the EU, showed some data, and did some institutional analysis with our friend Beach.

This week we'll look at the effects of tariffs, import quotas, and restrictive licensing, and derive some interesting and unexpected results from the analysis.
