2. How does the revenue effect of an import quota differ from that of a tariff?

A tariff is a tax on import able whereas an import quota is a direct quantitative restriction on trade which places an absolute limit upon the volume of imports that can be imported within a fixed time span.
In order to the compare revenue effects of tariff and import quota ,we can go for partial equilibrium or demand supply analysis. In fig2.1 the domestic supply curve and demand curve of a commodity is respectively S and D.
In autarky the equilibrium price and quantity of the goods produced is determined by the intersection of the domestic supply and demand curve. Market clearing autarkic price is Pt .If free trade prevails then price goes down to the international market clearing level Pw. At this price a country produces OT and consumes OW, thus imports TW amount of the good.
Now if the country(small) imposes a tariff of t per unit of the good imported , then domestic price raises immediately by the amount of tariff t ,and it becomes P*=(Pw+t).Increase in domestic price of the goods followed by a tariff has the following effects:
A) Consumption effect : consumption declines from OW to OV.
B) Output effect/protective effect: Higher price induces domestic producers to produce more. Domestic production and output rises from OT to OU.
C) Import reducing effect: as a result of increase in domestic output and a decrease in consumption demand the volume of import declined from TW to
