In a certain year, the strong economic growth of developing countries increased their purchase of raw materials, including copper, for production. On the other hand, several South American countries had serious safety issues in their copper mines and closed many of these copper mines. Suppose the above changes led an increase in the global sales volume of copper. Use a well-labeled demand-and-supply diagram to show the above effects on the global market of copper. Briefly explain your answer.

The benefits of each of them depend on whether or not the first enters and whether the second sets a high or low price: After analazing the graph, answer the following question: Great Brew threatens Little Kona by telling her, "If you go in, we're going to set a low price, so the best thing you can do is not get in." Do you think Little Kona should believe the threat? Why yes or why not?Food prices in sports stadiums are notoriously high because there is a limit on the numberof vendors that can operate in the stadium, which is a barrier to entry. In 2017, the AtlantaFalcons, an American football team, lowered the barriers to entry by allowing more foodvendors into their stadium. If the market for food in the stadium follows our perfect marketassumptions, what might you expect happened after this change? Do not worry about theunderlying facts of each statement, only whether it makes economic sense given our model.(Select one or more.)(a) The price of food in the stadium decreased because of an increase in supply.(b) The price of food in the stadium decreased because of an increase in demand.(c) The quantity of food sold decreased because of a movement of the supply curve.(d) The quantity of food sold increased because of a movement along the demand curve.(e) Profit per vendor decreased because of lower food prices.(f) Profit per vendor increased because of greater…
- 4. Read the following article: Your Avocados and Olives Are Pricier Because Fat Is In Fashion. a. In one to three sentences, briefly summarize the main point(s) of this article. The increase and popularity of healthy fatty food like avocados, butter, olive oil, and salmon are making these products spike in price because of their popularity. b. Draw two graphs side by side (like in problem 3 above) for an individual firm in a competitive market and the accompanying market. Draw them so they are in long run equilibrium initially. c. In the article, it mentions that the producers of avocados, fish, and butter are struggling to increase output (quantity supplied). Why? There was such a high rate of interest in these products in such a short amount of time, the companies weren’t able to fill the orders fast enough. d. Draw the effect described in part d on your graph of the market in part c. e. What happened to the equilibrium price as a result? What does the article…As more and more people bought home computers during the 1990s, the demand for access to the World Wide Web and the Internet increased sharply.

Despite a massive increase in demand, the price of access to the Web actually declined. Change in demand? Change in supply? Change in market equilibrium price? Change in market equilibrium quantity?Graph?You own Naughty Pine lumber and sell fence panels in a competitive market. Right now, your selling price is $130 for a fence panel, and you sell 8 panels a day. You are considering changing your price. You estimate that if you raise your price to $152 a panel, you would sell 7 panels a day. On the other hand, if you lower your price to $108 a panel, you would sell 12 panels a day. (a) Draw a graph of the above information. Label your axes, and the curve. Be sure your work is clear. (b) Use the MIDPOINT FORMULA to calculate Ed over the ranges below. Use TWO decimals in your answers. (i)Calculate the price elasticity of demand for a price change from $130 to $152 and daily Total Revenue if you change your price to $152 a panel (ii)Calculate the price elasticity of demand for a price change from $130 to $108 and daily Total Revenue if you change your price to $108 a panel Should you keep your current price, or raise the price, or lower the price?
- Now suppose that the state of Alabama eliminates its system of licensing Alabama alligator sausage producers. That is, suppose that it is no longer necessary to obtain a license from the state in order to produce Alabama alligator sausage. Suppose that the demand for Alabama alligator sausage increases. In the short run, what will happen to the price of Alabama alligator sausage, the profits of Alabama alligator sausage producers, and the number of Alabama alligator sausage producers? Explain your answers. In the long run, what will happen to the price of Alabama alligator sausage, the profits of Alabama alligator sausage producers, and the number of Alabama alligator sausage producers? Compare the long-run equilibrium to the equilibrium that existed before the increase in demand. Explain your answers. Which is better – having the licensing requirements or not having them? Justify your answer, being sure to explain what you mean by “better.”6. Individual and market supply Suppose that Andrew and Beth are the only suppliers of ice cream cones in a particular market. The following table shows their monthly supply schedules: On the following graph, plot Andrew's supply of ice cream cones using the green points (triangle symbol). Next, plot Beth's supply of ice cream cones using the purple points (diamond symbol). Finally, plot the market supply of ice cream cones using the orange points (square symbol). Note: Line segments will automatically connect the points. Remember to plot from left to right.In 1896, Colgate dental cream was introduced in tubes similar to those we use now. Today, the Colgate-Palmolive Company’s brand of toothpaste is the best-selling toothpaste in the world (ahead of the Crest brand marketed by Procter & Gamble, which was introduced in 1955). While Colgate and Crest enjoy the lion’s share of the toothpaste market, if you view the oral care shelf at your local drugstore or supermarket, you will find over a hundred different varieties of toothpaste. Colgate alone sells over 40 different varieties that are marketed under names ranging from Shrek Bubble Fruit to Colgate Total Advanced Whitening. The high level of product differentiation in the toothpaste market stems from firms introducing new varieties in an attempt to boost their economic profits. In environments where makers of other brands (such as Crest) can easily enter profitable segments of the market, a profitable strategy is to attempt to quickly cover that segment (introducing Shrek Bubble Fruit…

The owner of the café says that their supply schedule is QS = 1600 + 315p. i) Identify the café’s daily profit maximising price and quantity. ii) When a new hot chocolate machine is installed, the Professor finds that the supply schedule has changed to QS = 1625 + 365p. What are the café’s new daily profit maximising price and quantity? iii) Find the price elasticity of demand for the café’s hot chocolate and comment on the result.
