Chapter 15: Problem 12

The Asian rice-exporting nations planned to discuss a proposal that they form a cartel. Ahead of the meeting, the countries said that the purpose of the rice cartel would be to contribute to ensuring food stability, not just in an individual country but also to address food shortages in the region and the world. The cartel will not hoard rice and raise prices when there are shortages. The Philippines says that it is a bad idea. It will create an oligopoly, and the cartel could price the grain out of reach for millions of people. Source: CNN, May 6,2008 a. Assuming the rice-exporting nations become a profit-maximizing colluding oligopoly, explain how they would influence the global market for rice and the world price of rice. b. Assuming the rice-exporting nations become a profit-maximizing colluding oligopoly, draw a graph to illustrate their influence on the global market for rice. c. Even in the absence of international antitrust laws, why might it be difficult for this cartel to successfully collude? Use the ideas of game theory to explain.

Short Answer

Expert verified
A profit-maximizing colluding oligopoly would reduce output to increase prices, illustrated by a shift in the aggregate supply curve. Game theory suggests collusion is difficult due to incentives to cheat.

Step by step solution

01

Understanding the Question

Read the exercise carefully. It involves the formation of a rice-exporting cartel and its potential impact on the global market and prices. We are required to explain their influence, illustrate with a graph, and use game theory to analyze the difficulty of collusion.
02

Definition of a Profit-Maximizing Colluding Oligopoly

Define the concept of a profit-maximizing colluding oligopoly. A colluding oligopoly is a market situation where a few producers agree to set prices and output levels to maximize their joint profits, behaving like a monopolist.
03

Influence on Global Market and World Price

Explain how a profit-maximizing colluding oligopoly would influence the rice market. By reducing the total output of rice, these nations could increase the world price of rice. This higher price would maximize their collective profits at the expense of higher costs for consumers globally.
04

Graphical Representation

Draw a graph showing the influence on the global market. Plot the aggregate supply curve of the cartel, the global demand curve, and indicate the original price and quantity versus the cartel's reduced supply and increased price.
05

Discussing Collusion Difficulties Using Game Theory

Use the concepts of game theory to analyze the difficulties of collusion. Explain that each country has an incentive to cheat on the agreement to maximize individual profits while the others stick to the agreed output. This creates a 'prisoner's dilemma' situation where the incentive to defect is high.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Colluding Oligopoly
A colluding oligopoly happens when a small number of producers in a market agree to work together. They set prices and output levels to maximize their combined profits, much like a single monopoly. By agreeing on how much each can produce and at what price, they can jointly control the market.
Game Theory
Game theory is the study of strategic interactions where the outcome for each participant depends on the actions of all. It helps us understand competitive and cooperative behaviors in economics. In the context of a colluding oligopoly, game theory explains why sustaining collusion is challenging.
Each member of the cartel will have private incentives to cheat to increase their market share and profits. Yet, if all members cheat, the cartel’s ability to control prices collapses.
Supply and Demand Graph
To illustrate the impact of a colluding oligopoly on the global market for rice, let's use a supply and demand graph. On the vertical axis, we have the price of rice. On the horizontal axis, we have the quantity of rice.
The **global demand curve** slopes downward, indicating that as rice becomes cheaper, people buy more.
The **supply curve** of the cartel would be higher because the cartel would restrict output to increase prices. The result is a new equilibrium with a higher price and lower quantity compared to a competitive market.
Prisoner's Dilemma
The prisoner's dilemma in game theory shows why two rational individuals might not cooperate, even if it appears that cooperation is in their best interest.
Imagine two criminals are arrested and interrogated separately. Each has the option to betray the other or remain silent. Mutual cooperation (staying silent) yields the best joint outcome. However, each individual has an incentive to betray the other to minimize their personal sentence.
Similarly, in a colluding oligopoly, each nation has an incentive to cheat by selling more rice independently, hoping others adhere to the agreed restrictions. This pursuit of personal gain over joint gain can lead to the breakdown of the cartel.

All four leading U.S. airlines - American Airlines, Delta, United, and Southwest- are down about 10 percent from their respective highs set two weeks ago. The fall came after Southwest Airline's decision to increase fleet capacity 7 percent and American Airline's response that they will "compete aggressively" on price to retain customers from low-cost carriers resulting from capacity increases. Source: www.seekingalpha.com, June 1,2015 As implied in the news clip, what type of market best describes the U.S. airline industry?

Gadgets for Sale \(\ldots\) or Not How come the prices of some gadgets, like the iPod, are the same no matter where you shop? No, the answer isn't that Apple illegally manages prices. In reality, Apple uses an accepted retail strategy called minimum advertised price to discourage resellers from discounting. The minimum advertised price \((\mathrm{MAP})\) is the absolute lowest price of a product that resellers can advertise. Marketing subsidies offered by a manufacturer to its resellers usually keep the price at or above the MAP. Stable prices are important to the company that is both a manufacturer and a retailer. If Apple resellers advertised the iPod below cost. they could squeeze the Apple Stores out of their own markets. The downside to the price stability is that by limiting how low sellers can go, MAP keeps prices artificially high (or at least higher than they might otherwise be with unfettered price competition). Source: Slate, December 22, 2006 a. Describe the practice of resale price maintenance that violates the Sherman Act. b. Describe the MAP strategy used by Apple and explain how it differs from a resale price maintenance agreement that would violate the Sherman Act.

Use the following news clip to work. Bud and Wise are the only two producers of aniseed beer, a New Age product designed to displace root beer. Bud and Wise are trying to figure out how much of this new beer to produce. They know (i) If they both produce 10,000 gallons a day, they will make the maximum attainable joint economic profit of \(\$ 200,000\) a day, or \(\$ 100,000\) a day each. (ii) If either firm produces 20,000 gallons a day while the other produces 10,000 gallons a day, the one that produces 20,000 gallons will make an economic profit of \(\$ 150,000\) and the other will incur an economic loss of \(\$ 50,000\). (iii) If both produce 20,000 gallons a day, each firm will make zero economic profit. Construct a payoff matrix for the game that Bud and Wise must play.

Consider a game with two players who cannot communicate, and in which each player is asked a question. The players can answer honestly or lie. If both answer honestly, each receives \(\$ 100\). If one player answers honestly and the other lies, the liar receives \(\$ 500\) and the honest player gets nothing. If both lie, then each receives \(\$ 50\). a. Describe the strategies and the payoffs. b. Construct the payoff matrix. c. What is the equilibrium of this game? d. Compare this game to the prisoners' dilemma. Are the games similar or different? Explain.

New Entrants Pose a Challenge to Boeing's Share of the Global Commercial Airplane Market Competition is going to get tougher for Boeing. Currently, the global commercial airplane market for airplanes with a seating capacity of over 100 passengers is lead by Boeing and Airbus. Last year, Boeing with 648 commercial airplane deliveries occupied 43 percent of this market. Airbus with 626 commercial airplane deliveries stood second. Source: Forbes, March 06,2014 a. According to Reuters, the market share of Boeing in the large commercial aircraft segment was above 75 percent before 1990 Describe how the structure of the airplane market has changed over the past few decades. b. If Boeing and Airbus formed a cartel, how would the price charged for airplanes and the profits made change?
