A major South African city generates electricity and sells it to its consumers. The city faces competition from independentrenewable power producers who also have licences to sell electricity to the public. The city however has cost advantagesdue to its size, but it is concerned of the political and economic ramifications of raising its tariffs, in these uncertaineconomic times. As a result, it is highly likely that tariffs will remain unchanged over the next financial year. The city’smarginal revenue is given as R3 000, and its costs are given as follows:TC = R82 000 + R1 000 + 0.01q2 MCMC= R1 000 + R0.02q4.1 Assess the efficiency arguments in favour of and against the renewable energy generation in SouthAfrica

Steel is produced only in the US and the rest of the world (ROW). The inverse demand and supply in the US are p = 110 - Q8 and p = 20 + Qỗ, while in the ROW, they are p = 70 - Q and p = Qk. All quantities are in millions of tons and all prices are in dollars per ton. Since steel is produced more cheaply in the ROW, the US imports it from the ROW under international trade. At any price, p, the imports of the US, QM. is the excess demand for steel given by the difference between the quantity demanded and the quantity supplied domestically in the US: QM = Q% - Qi. Similarly, the exports of the ROw, QF, is the excess supply of steel given by the difference between how much they produce and how much they demand: QE = Qk - Qg. (b) Find the consumer and producer surplus in the US at the price p". consumer surplus $ million producer surplus million (c) The US government imposes a tax of $12 per unit on the ROw's exports. Find the new world equilibrium price, p**, and new world equilibrium…

In the world market, a pair of shoes from China is sold for $40 and that from Mexico is $50. U.S. made shoes are $70 a pair. Initially U.S. does not belong to any free trade agreement and imposes an ad valorem tariff of 30%. Later, the U.S. joins a free trade agreement with Mexico and remove all trade barriers including tariffs. The import demand function for the U.S. is Q = 280 – 4P. (Hint: Draw the import demand curve of the world market as shown in the examples on the textbook and lecture slides.) 13. How much will the U.S. government tariff revenue change (as a result of this free trade agreement? а. Increase by $144 O b. Decrease by $720 C. Decrease by $800 O d. Decrease by $864

The increase in prices resulting from the levy of import duty usually reduces the consumption capacity of thepeople.  True False

canada has not allowed for the bulk exportation of water. the current price for water for canadian consumers is $40 per tonne (typically delivered via an underground pipe to your house/business!) and canadians consume 3 m tonnes/yr. unfortunately, climate change has resulted in droughts in california and other southern states. to help meet this need and make a profit of course, canada has decided to allow international trade in water. the north america (or world) price for water is currently $60/tonne. (hint the supply lines does not move….) Explain in words:-1) what will happen to production (supply) and canadian demand for water. 2) The effect on the producer and consumer surplus.  3) any imports / exports

"Trinidad and Tobago is not only impacted by the economic consequences of COVID-19; but as an oil-and-gas exporting country, the economic, financial and social consequences have been further compounded by the dramatic drop in oil and gas prices. The worldwide demand for crude oil has crashed in the context of stay-home-lockdown orders. As I indicated earlier, on April 20, 2020, the price of West Texas Intermediate (WTI) took an unprecedented turn entering negative territory for the first time in its history, The WTI June 2020 delivery for crude oil is currently US$15 per barrel and the natural gas June futures price is US$1.82 per MMBTU." "The Central Bank of Trinidad and Tobago is helping the economy navigate through these difficult circumstances. For example, the Central Bank has reduced the reserve requirements for the commercial banks from 17.0 percent to 14.0 percent; and the repo rate from 5.0 percent to 3.5 percent. As a result, Commercial banks have reduced their prime lending…

GlobalCell is an American firm producing cell phones. GlobalCell imports cell phone components from Japan and assembles them domestically. Suppose that in the United States, a cell phone sells for $100 and that 60% of the cell phone's value comes from the value of the imported components. The United States imposes a 30% tariff on cell phones and a 10% tariff on the cell phone's components. Assume that costs of producing components are the same in the United States and Japan and that transit costs are nonexistent. Based on the information provided, the effective rate of protection that GlobalCell receives from the tariff is A. 60% B. -20% C. -13.3% D. 26.7%

Suppose that the world price of oil is roughly $90.00 per barrel and that the world demand and total world supply of oil equal 34 billion barrels per year (bb/yr), with a competitive supply of 20 bb/yr and 14 bb/yr from OPEC. Statistical studies have shown that the long-run price elasticity of demand for oil is -0.40, and the long-run competitive price elasticity of supply is 0.40. Using this information, derive linear demand and competitive supply curves for oil. Let the demand curve be of the general form Q=a-bP and the competitive supply curve be of the general form Q=c+dP, where a, b, c, and d are constants. The equation for the long-run demand curve is A.Q=47.50-0.15P. B.Q=13.50-47.50P. C.Q=47.50-P. D.Q=47.50+0.15P. E.Q=13.50-0.15P.
