- James mainly sells confectionery items, newspapers, magazines and cigarettes in his convenience store. Noting his small business is not thriving, he thought of selling hot pies and rolls too. Suppose the total cost function for rolls and pies is, TC = 900 + 50Q, Q = Q1 + Q2 Where Q1 and Q2denote the quantities of rolls and pies respectfully. If P1 and P2 denote the corresponding prices, the inverse demand equations are. Q1 = 70 - P1 and 0.5Q2 = 100 - P2 a)If James decides to make a total of 48 rolls and pies per day and charges different prices as above (that is, P1 ≠ P2 ), how many of rolls and pies each should he make in order to maximize the profit of a particular day? Estimate and interpret the Lagrange Multiplier λ [note: assume second-order conditions are satisfied]. b)Using your knowledge of input-output tables, explain which components of the economy will be affected if all convenience stores, including James’, closed down for three months due to the COVID-19. What would…Suppose that the marginal revenue fron selling sandwiches is constant at $9 per sandwich. Use the folllowing cost function to determane the optimal number of sandwiches to produce/sell. TC=Q2Consider a competitive market for red lentils with 100 identical farmers in Horsham Victoria, a competitive market price of $5 and the following MC for each farmer: MC = $0.05Q Also consider the following market demand function: QD a) Calculate the optimal level of production (in tonnes) for each farmer (show workings) = = 1000 - 40P b) Assuming 100 lentil farmers of equal size how many tonnes of lentils in total will be supplied in the entire market? (show all workings) c) Consider that the government now imposes a 25% tax on producers, calculate i) the new equilibrium level of output for each firm (hint - think about how this affects each farmer's marginal cost), and ii) new total supply in the entire market (show all workings)
- Please no written by hand solutions 2. Mr Gieves and Mr Hawkes produce items of clothing. The market demand for clothes is y = 13-p with y = y1+y2 and p denoting the market price of clothes. Mr Gieves and Mr Hawkes compete by simultaneously choosing the quantity of clothes to send to the market, and their cost functions are C1 (y1) = y₁ and C₂(y2) = y2 respectively. (a) Set up the profit functions, and derive the reaction functions. (b) Find the Cournot equilibrium of the market. Indicate what the market price, individual outputs and profits are.In 2020, the town of Rollaville had a more-or-less competitive market for hot pretzel stands. Any respectable seller could set up a hot pretzel stand as long as certain health requirements are met. Each stand has the constant marginal cost of $4 per pretzel and can make 40 hot pretzels per day. Let the demand function for hot pretzels be given by D(p) = 600 - 40p, where demand is measured in number of hot pretzels per day, and price is measured in dollars. Assume that the industry is perfectly competitive. 1. In equilibrium, the price will be [Select] and there will be [Select] hot pretzel stands in equilibrium. 2. In 2021, the City Council of Rollaville created a hot pretzel stand licensing board and issued a license to each of the existing stands. The board stated that they would issue no more new licenses in 2021. Costs had not changed, but the demand curve for hot pretzel had become D(p) = 680 - 40p. The the new equilibrium price of a hot pretzel in 2021 is [Select] 3. In 2022, the…Question Road Runner Co is a Pakistani manufacturer making Bicycles. It exports to two markets,Bangladesh and Sri Lanka. Demand for Bicycles in thesetwo markets is given by the following Functions: Bangladesh Q1 = 12 – P1 Sri Lanka Q2 = 8 – P2 Where Q1 and Q2 are respective quantities sold (in thousands) andP1 and P2 are the respective prices (in Pak. Rupees per unit) in the two markets. Total cost function is C = 5 + 2 (Q1+ Q2) Now consider two cases (i) Company is effectively able to price discriminate in the two markets. What will be the total profits? (ii) Suppose the company does not engage in price discrimination. By charging the same price in the two markets what are the profit maximizing levels of price, output, and the total profits? c. Analyze, with graphs, the two alternative pricing strategies…
- An industrial firm makes two products, A and B. These products require water resources where they are very scarce. The products they make are unique, and hence they can set the unit price of each product at any value they want to. However, experience tells them that the higher the unit price for a product, the less amount of that product they will sell. The relationship between the unit price and quantity that can be sold is given by the following two demand functions: Assume for simplicity that the unit price for product A is (16 - A) and for product B is (18-2.5B). Suppose the total amount of A and B could not exceed the total amount of Tmax. Where Tmax = 10. Please use "Lagrange Multiplier" method to determine what are the amounts of A and B, and their unit prices, that maximize total revenue (Set the marginal increments at 1).An industry has the following cost function: C(X, Y ) = 1500+20X +20Y . Market demands for the 2 goods are given by PX =80−X, and PY =140−2Y Suppose the government wished to use two part tariffs in these markets, and suppose further that two part tariffs are feasible. Imagine that there are 10 consumer in each market. Solve for a set of two part tariffs (one for each martket) that pay the firm zero profits in total, yet achieves efficiency.Road Runner Co is a Pakistani manufacturer making Bicycles.
