Consumption Effect: Reduction in the consumption or demand for G on account of import duty is termed its consumption effect. the tariff forces them down their supply curve, and they end up exporting less coffee and selling it for a lower price. Effect of Increased Trade. The effects of tariffs-The export supply curve-The import demand curve-The world equilibrium-Effective rate of protection-The welfare costs of tariff ( CS and PSefficiency loss, terms of trade gain, tariff revenue) Import quota-Quota rent and the welfare cost of quota (rent seeking activity) Effects of an Export Subsidy Local Content Requirement VER- A tariff has protective effect for the domestic industries. The labor demand curve is the MRP. Now an ad valorem tariff T, is applied, which raise the free trade supply curve (assuming foreign prices remain unchanged as a result), by Sd + Sf + T. Equilibrium now shifts to point Q. This is the elasticity of demand, or the slope of the demand curve. The imposition of a tariff shifts up the world supply curve to World Supply + Tariff. Market for Workers in an Import Industry. D. 2. Tabarrok then shows the effect of a Tariff. So they suffer a loss in producer surplus of $175 million. is labor demand before the increase in trade; D. 2. is labor demand after the trade increase. In short, there are several means to discourage the inflow – or outflow- of traded goods. The Imports will be the quantity supplied with free trade minus the quantity supplied with no international trade as illustrated below. Let us take a product, say computer, in which India has a comparative disadvan­tage. As a result, domestic producers’ share falls to Q1 and imports now dominate, with the quantity imported Q1 to Q2. Governments impose tariffs to discourage consumers from buying imported products by simply making them more expensive to purchase. As seen above, this is a part of the trade effect. This a tariff that goes into effect after a quota threshold is exceeded. In the diagram below, you can see a Local Demand and Local Supply curve. This effect varies inversely with the slope of the domestic supply curve, and directly with the rate of the tariff. We use partial equilibrium ap­proach represented by supply and demand analysis to examine the effects of tariffs. If a country opens up to world supply, price falls to P1, and output increases from Q to Q2. L. 2. It may also be termed the demand effect of the tariff. In Figure 2, DD and SS are the domestic demand and supply curves of the commodity in question. Supply, Demand, and Tariffs. W. 2. As a result of the tariff, the domestic price has gone up to P 2 causing a reduction of consumption to OQ 4 . Thus, with free trade, the country supplies and demands the good in the amounts S F and D F respectively, as determined by the supply and demand curves. 36.1 we have drawn domestic demand and supply curve D d and S A respec­tively of computers in India. The price rises to P2, and the new output is at Q3. For example, the general tariff rate on an imported microwave oven is 2%. As you can see from the graph below, S0 and D0 represent the original supply and demand curves, which intersect at (P0, Q0). In Fig. 4. The total losses exceed the gains, but the loss in producers’ surplus is suffered by foreigners and — ha ha! Let’s suppose, that the function of demand of potatoes is given by Q_D = 20 – P and the function of the supply of potatoes is given by Q_S = 4P – 5. It tends to raise the domestic price of the imported commodity, reduce the domestic demand for that commodity and thereby stimulates its domestic produc­tion. Your instructor asks you to determine P_E and Q_E and plot the demand and supply curves if the government has imposed an indirect tax at a rate of \$\,1.25 from each sold kilogram of potatoes. L. The world price is lower than the price in the US without trade. Tabarrok compares the domestic supply and demand in situation with Free Trade with that of a situation of no international trade. D. 1 . — we don’t care about them. The World Supply curve demotes imported goods. If that were not the case, a tariff on imports would have no effect.
