Which of the following is true about the concept of concentration? Group of answer choices The lower the degree of rivalry amongst the firms, the higher the concentration. The lower the number of firms in a market, the lower the concentration. All of the answers are correct. The higher the degree of rivalry amongst the firms, the lower the concentration

To answer this question, you will want to work out the answer using a graph on a piece of scratch paper (not turned in). You are going to compare the outcomes in the case where there is perfect competition to the monopoly case. So, as an intermediate step, you will need to compute the equilibrium outcomes under competition and monopoly. Suppose that you have the following information about the demand for oil. Price ($/barrel) 80 70 60 50 40 30 20 10 Suppose that the marginal cost to produce a barrel of oil is $20. What is the deadweight loss if the oil market is a monopoly? Quantity demanded(# barrels) 5 6 7 8 9 10 11 12

1. Ten firms compete in a market to sell product X. The total sales of all firms selling the product are $3 million. Ranking the firms' sales from highest to lowest, we find the top four firms' sales to be $540,000, $430,000, $370,000, and $355,000, respectively. Calculate the four-firm concentration ratio in the market for product X.

Many European governments are reluctant to allow online betting in an attempt to protect their national gambling businesses. A recent study found that seven countries out of the 27 in the European Union banned online gambling. Of the other 20 only 13 have opened their markets to competition; in the rest gambling is dominated by monopolies owned or licensed by the government. In the Netherlands, for example, residents can only place online bets with a state monopoly: De Lotto. The Ministry of Justice even warned banks in the country that they could be prosecuted if they transferred money to online gambling companies. Other countries have ordered online betting companies to block access to their sites. Their governments argue that this is to protect people from gambling excessively. However the revenue they gain from their own monopolies should not be ignored as a possible motive. Questions  If governments believe that gambling is bad for their citizens then in economic terms how would…

Scenario Use the following information to answer questions 16-19. The graph below shows the market demand for computers in a small country. To develop a domestic computer industry, the government prohibits imports of computers and gives a single local firm the sole right to produce and sell computers (that is, it is a legal monopoly). The demand curve shows the local demand for computers. The cost curves show the marginal cost (MC) and average total cost (ATC) of the single producer. The graph also shows the marginal revenue (MR) curve faced by this firm. Price per computer (Dollars) $3500 $3000 $2500 $2000 $1500 $1000 $500 0 MR MC.. ATC Demand 10 20 30 40 50 60 70 Quantity of computers (number per year)

Monopoly outcome versus perfectly competitive outcome Consider the daily market for hot dogs in a small city. Suppose that this market is in long-run perfectly competitive equilibrium, with many hot dog stands in the city, each one selling the same kind of hot dogs. Therefore, each vendor is a price taker and possesses no market power. The following graph shows the demand (D) and supply curves (S = MC) in the market for hot dogs. Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from perfect competition. Use the green point (triangle symbol) to shade the area that represents consumers’ surplus, and use the purple point (diamond symbol) to shade the area that represents producers’ surplus.   (graph 1)   Assume that one of the hot dog vendors successfully lobbies the city council to obtain the exclusive right to sell hot dogs within the city limits. This firm buys up all the rest of the hot dog vendors in the city and…

Draw the graph for a monopoly earning a positive economic profit. Suppose the government institutes a per unit tax on the good produced by the monopoly (consider the impact it will have on the cost curves). On the graph, show how this will affect the monopoly’s profit maximizing level of output and the price charged by the monopoly. Draw and Label Price Axis, Quantity Axis, Demand Curve, Marginal Revenue Curve, Marginal Cost Curve, Average Total Cost Curve, New Marginal Cost Curve, New ATC Curve, Qm, MR=MC, MR=MC1 Qm1, Pm, Pm1, ATC point, ATC1 point, Deadweight Loss, Total Revenue, Total Cost, Profit

The figure below illustrates the market for steel. If the steel market is competitive, firms can produce steel at a constant marginal cost of $100 per ton. Therefore, the price of steel is $100 per ton, and 100 tons are produced. Assume that if all the steel companies consolidate into a monopoly, the monopoly marginal cost will fall to $70 per ton. Use the straight line tool to draw the monopoly marginal revenue and marginal cost lines (extend the marginal cost line to 300 tons). Then use the plot point tool to plot the monopoly profit maximizing price and output on the demand curve. Part 2. If the market is competitive, total surplus is $ _________ Part 3. If the market is controlled by a monopoly, total surplus is $________
