Given the demand curve in the following graph, find (and label) the monopolist’s profit-maximizing output and price. In this graph the monopolist’s profit-maximizing output is equal 3 and the monopolist’s profit-maximizing price is equal 8.

2. Show graphically an example of a monopolist that is producing the profit-maximizing output, but is not making a profit. The monopolist loss when the Average Total Cost exceeds the price that the monopolist can charge at the profit maximizing level of output.

3. Suppose the demand curve for a monopolist is Qd= 500-P, and the marginal revenue function is MR= 500-2Q. The monopolist has a constant marginal and average total cost of $50.00 per unit.

a. Find the monopolist’s profit-maximizing output and price.

Qd= 500-P MR =500-2Q ATC= 50 MC=50

MR = MC Qd= 500 - P
500- 2Q = 50 225 = 500 – P
-2 Q = 50 -500 = -450 - P= 225-500 = -275
Q= -450/-2 = 225 P= 275

The monopolist’s profit-maximizing output is 225, and the monopolist’s profit-maximizing price is 275.

b. Calculate the monopolist’s profit.

PR = TR – TC = (P * Q) – TC = ( 225 * 275 ) – ( 225 * 50) = 50625

The monopolist profit is 50625

c. What is the Lerner Index for this Industry?

L = ( P – MC ) / P = 275- 50 / 275 = 0.82

2. a. Define the term: Dominant Strategy.

Dominant Strategy is the strategy that result in the best outcome to given company in the Industry, no matter what action or choice the other company makes.

b. Define the term: Nash equilibrium.

Nash equilibrium is the strategy that managers choose that is the best for them, given the assumption that their competitors will choose its best strategy.

Business Models in the Video Game Industry

...When the refinement of products and services, or the monetary flow has two directions, it is referred as Two-Sided Business Models. The concept of a value chain and terms such as upstream and downstream is not as clear as in One-Sided Business Models. Development can be made by what is in One-Sided Business Models referred to as downstream actors and monetary flow can come from actors referred to as upstream. Two – Sided Business Models are also mentioned as “Multi-sided Platforms”. One of the best examples for “Multi-sided Platform” is gaming platforms. The platform’s value for a particular user group depends substantially on the number of users on the platform’s “other sides”. A video game console will only attract buyers if enough games are available for the platform. On the other hand, game developers will...

Emi Case Study

...independent music company and is 3rd among the top 5 music companies globally, with 12.6% of the global market share. The firm engages in the recording, producing, and distribution of music, mainly through CDs. EMI is a British based company, but North America is the largest market for the music industry. CD buyers have low brand awareness and loyalty. They typically don’t even know the music company that is producing the product. Brand awareness for the artist is very high and will drive the purchase decision almost exclusively. Buyers will seek out a store to purchase the music they desire. However, brand loyalty is low, with many “one hit wonders” that are #1 sellers one year, then gone the next. CDs are durable goods. They last a long time, but people’s tastes for music may change and, thus, categorizes them as a non-durable good. In this case, it is more about music than the actual CD. The location of the purchase decision has changed dramatically with a significant number of people using the Internet to illegally share music files. EMI and its recording artists do not receive any compensation from music file sharing. Those music consumers who remain have shifted from music stores to mass marketers. The market for CDs in the United States is splintered into different genres, with Rock, Rap/R&B, and Country as the top 3 in that order, comprising 60% of the US market. Demographics show that the greatest loss has been in ages 15-29, who have adopted online sites as...

Building Competitive Advantage Through Business-Level Strategy

...a company to gain a competitive advantage over its rivals in a market or industry. The way that strategic managers define their company’s business is the first step in crafting business level strategy. Customer Needs and Product Differentiation Customer needs are desired, wants or cravings that can be satisfied by means of the attributes or characteristics of a product a good or service. Two factors determine which product a customer chooses to satisfy these needs: The price of the product and the way a product is diffetentiated from other products of its type. Product differentiation is the process of designing products to satisfy customers needs. A company obtains a competitive advantage when it creates, designs, and supplies a product in a way that better satisfies customer needs than its rivals do and chooses the correct pricing option the one that results in the level of demand that optimizes profitability. Customer Groups and Market Segmentation Market Segmentation is the way a company decides to group customers, based on important differences in their needs or preferences, in order to gain a competitive advantage. One principal way of grouping customers and segmenting the market is by what customers are able and willing to pay for a particular product, the other principal method of segmenting customers is according to the specific kinds of need that is being satisfied by a particular product. Market segmentation is an evolving, ongoing process that presents considerable...

Bitter Competition

...Bain-Chekal Introduction: The worldwide aspartame market has enjoyed patent protected financial prosperity since the early 1980’s. In 1986 the world demand for aspartame was 5,730 tons annually with future projected world demand reaching 10,000 tons annually, a 75% increase over 1986 demand. The Monsanto Corporation, the current owner of the rights to manufacture aspartame, under the brand name NutraSweet (NS), reported 1986 sales of $711 million. The estimated ROA was approximately 8%.1 With this being such an attractive industry, companies like Holland Sweetener Company (HSC) needed to determine whether or not to compete in the aspartame business. This paper will first analyze NS’s case for accommodating or deterring entry before turning to a discussion as to which strategy NS will actually choose. Given the above analysis the paper will briefly address what Holland Sweetener Company’s entry strategy should be. There are several industry factors that will affect how this game is played. First, the two versions of aspartame, as produced by HSC and NS, are relatively identical goods. This leaves the consumer indifferent to product attributes and only concerned with price. It is also assumed that geography is not a real strategic factor since shipping costs are so low. The shipping costs for a pound of aspartame average 15-20 cents.2 Compared to the 1986 market price of $70 per pound shipping costs only account for 0.002% of the market price, hardly a significant factor of concern...

Video Game Industry

...VIDEO GAME INDUSTRY Son Tung Nikkila ID: 61191023 Introduction The first video game, Spacewar, which was created by Steve Russell in 1960s, marked a beginning of the video game industry. However, video games were not commercized until 1970, when Nolan Bushnell made a clone of Spacewar, called it Computer Space, and marketed it to the market in the form of a coin-operating arcade machine. And thus the video game industry started (Kline, Dyer-Witheford & Peuter, 2003). As video game expanded people spent less time on TV and spent more time on video game (Allen & Kim, 2005). In their article “Paradigm shifts in the video game industry”, Zackariasson and Wilson (2010) wrote about four important shifts in the video game industry: the starting period of video game industry, the development of the home cartridge, the entry of independent game developer-publishers, and the development of massively multiplayer online role playing games, known as MMORPG. According to the authors, those changes in the industry had an impact on its competition and culture (Zackariasson & Wilson, 2010). Kline, Dyer-Witheford and Peuter (2003) also mentioned about the starting period of the video game industry and agreed that it marked a great beginning of the industry. Along with the fast growth, the authors also brought up how the fast growing industry came to an end in 1984. However, not long after the meltdown of the industry, Nintendo stepped in and rescued the industry with its...

Game Theory and the Prisoner's Dilemma

...Game Theory and the Prisoner’s Dilemma Business Strategy Antoinette Monteiro Grand Canyon University DBA 815 January 13, 2016 The Definition of Game Theory The game is the object of game theory, which is an interactive situation. There are several players involved in the situation; a game with only one person is a decision problem. According to game theory, the players, their preferences, their information, the strategic actions available to them, affects the outcome. Game theory is conflict and cooperation; the agents are interdependent on the actions of others. These agents are individuals, groups, firms or a combination of these combined. Game theory provides a language to formulate, structure, analyze and understand different circumstances (Turocy and Stengel, 2001 p.4). History and Effects of Game Theory An example of game analysis is the idea of two players dominating the marketplace which was introduced by Antoine Cournot in 1838. Emile Borel, a mathematician proposed a game theory in 1921 and this research was expanded by Neumann in 1928 called the “theory of parlor games.” This theory was solidified in the publication, “The Theory of Games and Economic Behavior by Neumann and Morgenstern. This book pioneers the basic terms and problems that are still in use to this day (Turocy and Stengel, 2001, p.4). The mathematician, John Nash showed that finite games have an equilibrium point in which players choose actions which give the best outcome for themselves...
