Q.1. Suppose that the demand for steel in Japan is given by the equation Q's = 1200- 4Ps + PA+ PT, where QS is the quantity of steel purchased (millions of tons peryear), PS is the price of steel (yen per ton), PA is the price of aluminum (yen per ton),and PT is the price of titanium (yen per ton). The supply curve for steel is given by Q$s= 4Ps. Similarly, the demand and supply curves for aluminum and for titanium aregiven by Q'A = 1200 – 4PA + Ps + PT (demand curve for aluminum), Q°A = 4PA (supplycurve for aluminum), Qʻr= 1200 – 4PT + Ps+ PA (demand curve for titanium), and QST= 4PT (supply curve for aluminum).a) Find the equilibrium prices of steel, aluminum, and titanium in Japan.b) Suppose that a strike in the Japanese steel industry shifts the supply curve for steelto Q°s = Ps. What does this do to the prices of steel, aluminum, and titanium?c) Suppose that growth in the Japanese beer industry, a big buyer of aluminum cans,fuels an increase in the demand for aluminum so that the demand curve for aluminumbecomes Q'A = 1500 – 4PA + Ps + Pr. How does this affect the prices of steel,aluminum, and titanium?

During the 1980s, most of the world’s supply of lysine was produced by a Japanese company named Ajinomoto. Lysine is an essential amino acid that is an important livestock feed component. At this time, the United States imported most of the world’s supply of lysine—more than 30,000 tons—to use in livestock feed at a price of $1.65 per pound. The worldwide market for lysine, however, fundamentally changed in 1991 when U.S.-based Archer Daniels Midland (ADM) began producing lysine—a move that doubled worldwide production capacity. Experts conjectured that Ajinomoto and ADM had similar cost structures and that the marginal cost of producing and distributing lysine was approximately $0.70 per pound. Despite ADM’s entry into the lysine market, suppose demand remained constant at Q = 208 − 80P (in millions of pounds). Shortly after ADM began producing lysine, the worldwide price dropped to $0.70. By 1993, however, the price of lysine shot back up to $1.65. Use the theories discussed in this…
Recently, China placed tariffs on the importation of US soybeans. Assume that the domestic market for soybeans in China is described by the following equations: Demand: P = 11.5 – Q Supply: P = 5.5 + Q Price is in 10 Yuan (¥) per bushel of soybeans and the units for Quantity are 100 million bushels per year. This is to make graphing simpler. This does NOT mean that the price is 10 and quantity is 100. Rather it means that if the price was 40¥ and the quantity was 7,500,000,000 bushels, this would plot as 4 and 7.5 respectively. The world price for soybeans is ¥65/bushel (this would graph as 6.5). Graph the soybean market in China showing equilibrium both with no barriers to trade and with a ¥15/bushel tariff. Be sure to fully and clearly label the graph including: Domestic Demand curve (D), Domestic Supply curve (S), the World Price (WP), and the Price with tariffs (PT). Based on your graph for question 3, what amount of soybeans will China import from the US if there are no…
Suppose that the world price of oil is roughly $50.00 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 f 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 O A. Q=47.50 -0.27P. O B. Q=13.50 -0.27P. OC. Q=47.50-P O D. Q=47.50+ 0.27P. O E. Q=13.50-47.50P. The equation for the long-run competitive supply curve is O A. Q=12.00 + 47.50P. OB. Q=12.00 -0.16P. OC. Q 8.00+ 0.16P. O D. Q=8.00+ 0.27P. O E. Q=12.00 +0.16P.

The domestic demand (Qpp) for wheat in the United States is estimated to be QDD=1430-55P, where the quantity of wheat is measured in millions of bushels per year. Suppose China also demands U.S. wheat (Qpc) and that its demand is given by QDc=1920-60P. What is the total demand for U.S. wheat, assuming the only two sources of demand are domestic and Chinese? The total demand for U.S. wheat is OA. Qp =3350-115P for all P. O B. Q =3350-115P for P≤ $26 and Qp = 1920-60P for P> $26. OC. Q=1920-60P for all P. O D.

Consider the market for sweet cherries in the Yakima Valley in Washington. The following are the equations of the supply and demand curves for sweet cherries in the Yakima Valley: Pd=452-Qd or Qd-452-Pd Ps=(1/450) * Qs+1 or Qs=450 * Ps-450=450 * (Ps-1) In these equations, P is the Price/lb of sweet cherries in the Yakima Valley, and Qd and Qs are the quantity demanded and the quantity supplied of cherries in milliion lbs per year. a) complete the table to find the Qd, Qs b) what are the equilibrium P and Q of cherries? c) Suppose that the P of sour cherries, a substitute of the sweet cherries, decreases. As a result the D curve for sweet cherries shifts, and the new D curve is given by the following equation: P=361.8-Qd or Qd-361.8-P Fill the Qd_d column of the table with your answers.
Home has 12,000 units of labor available. It can produce two goods, apples and bananas. The unit labor requirement in apple production is 100, while in banana production is 75. There is now also another country, Foreign, with a labor force of 18,000. Foreign’s unit labor requirement in apple production is 120, while in banana production is 150.

The market for gravel has the following demand and supply relationships: Supply function: Q = 100P - 1,000 Inverse demand function: P = 50 - 0.01*Q + PX, where P represents price of gravel per ton in dollars, Q represents sales of gravel per week in tons, and PX is the price of some other product X in dollars per unit. Let PX = $50/ton In a diagram, qualitatively describe the change that would occur in the market for gravel (i.e. equilibrium price and quantity) if a new discovery has just made the production of product X cheaper. Briefly explain whether it is a movement along or shift of demand curve and supply curve for gravel. In addition to the new discovery regarding product X in previous question), suppose now workers producing gravel ask for sick leave due to COVID. Use supply and demand analysis to predict how these two shocks will affect equilibrium price and sales. Illustrate your results in a diagram. Is there enough information to determine if market prices will rise or…

Consider the demand function for processed pork in Canada, Q = 171 - 20p + 20p, + 3p, + 0.002Y where Q is the quantity of pork demanded (measured in millions of kg per year), p is the price of pork, Ph is the price of beef, Pc is the price of chicken, and Y is the income of consumers. If per capita income, Y, increases by $180 a year, then the quantity demanded changes by million kg. per year.
