In the Disney movie Frozen, the Kingdom of Arendelle changes overnight from a warm, flower filled place to being completely frozen (the story takes place in July).  Just after this change in weather, there is a scene where two characters visit a trading post.  At the trading post one character (Kristoff) is looking to buy winter transportation equipment and eventually sell some ice.  The other character (Anna) is looking to buy some winter clothes.  A link to the scene can be found in the module. For this assignment, please show how this change in weather would likely effect the markets for winter transportation equipment, winter clothes, and ice (assume the ice would be used by people who want to cool drinks).  Specifically, draw a new supply or demand curve for the products and identify new equilibrium quantity or supply if you think the change in weather would have an impact on any of those measurements. In the clip Kristoff calls Oaken a crook for charging higher prices than he…

Assume the market clearing price is $5.00 for deli sandwiches and the amount of exchange that would take place at that price is 200 deli sandwiches per day. You, however, don't have this information and have just opened your deli. You decide to price your sandwiches at $9.00 and are willing and able to sell 285 sandwiches per day at that price. When you do this, you notice you sell 100 sandwiches per day. Draw this situation on a graph and then explain what will happen in this market -- i. e., if there is a shortage or surplus, show this on the graph and then explain what the shortage or surplus will cause to happen in the market. Make sure you talk about inventories in your answer.

Karan and Arjun work for a political campaign for 20 hours each per week. It takes Karan 2 hours to make a poster and 5 hours to write a memo. It takes Arjun 4 hours to make a poster and X hours to write a memo. The campaign needs 10 posters this week, and as many memos as possible. Since Karan is faster at making posters, he should be assigned the task of making posters.

A consumer has preferences over two goods, carrots and turnips, each measured in kilograms. For each of the following scenarios, identify which, if any, of the standard assumptions of preferences are violated. (a) The consumer will never eat more than ten kilograms of carrots per day. (b) The consumer cares only about the total weight of the two vegetables consumed, and always prefers more to less. (c) The consumer cares only about the product of the respective weights of the two vegetables consumed, and always prefers a greater product to a lesser one.

Ginny likes to eat Bertie Bott’s Every Flavour Beans (b), and Chocolate Frogs (f). Herpreferences over these lollies are Cobb-Douglas, and can be presented by the utility functionu(b, f) = 1/5(b − 2)(f + 3). Each Every Flavour Bean costs 25 Knuts and each Chocolate Frogcosts 12 Knuts. Ginny has 314 Knuts to spend. Assume that beans and frogs are both perfectlydivisible goods.(a) Find Ginny’s optimal bundle.(b) Suppose that Ginny is mugged by Draco on her way to the lolly cart, so that by the timeshe is there, she is left only with 75 Knuts. What is her optimal bundle now?(c) Now, consider the general case, where Ginny’s income is m, the price of Every FlavourBeans is pb, and the price of Chocolate Frogs is given by pf . In other words, treat ChocolateFrogs as the numeraire. Find Ginny’s demand for each good in terms of m, pb and pf .(d) Find the good on which Ginny will always spend more than half of her income.(e) Find the own-price, cross-price, and income elasticities of good 2…

In the diagram to the right, we have five different combinations of movies and books. Combination A represents 2 movies and 3 books. Combination C represents more books (7) and the same number of movies (2). Points B, E, and F are other combinations with more movies, more books, or more of both. When compared to combination A, combination B provides satisfaction to the consumer. When compared to combination F, combination B provides satisfaction to the consumer. When compared to combination A, combination F provides satisfaction to the consumer. These conclusions are based on what assumption about preferences?
