MONOPOLY
To better predict a company's future profit stream, a financial analyst needs to know about market structures.
The ideal marginal cost and marginal revenue are equal.However, the marginal revenue and price are equal only in perfect competition. Price typically exceeds marginal revenue in the remaining structures because a company can only sell more units by lowering the price per unit.
Perfect competition results in the highest selling volume.In perfect competition, the price is typically the lowest, but this depends on things like demand elasticity and growing returns to scale (which may lower the producer's marginal cost).In monopolistic competition, producers, oligopolists,and monopolists attempt to differentiate their products in order to charge higher prices.
Monopolies typically charge more for smaller quantities.Being a shareholder in monopolistic businesses with substantial positive cash flows and high margins could be advantageous to investors.
Economic profit is not made by competitive businesses.The rental of capital and management services will be compensated by the market, but there won't be any additional margins due to the lack of pricing power.
While businesses in any market structure can make money in the short term, the faster the extra profits will disappear, the more competitive a market is and the lower the barriers to entry.Long-term, new entrants reduce margins and drive the least efficient businesses out of the market.
The importance of strategic behavior defines oligopoly.To gain an advantage over their rivals, businesses can alter the product's price, quantity, quality, and advertising. TheThe likelihood that each of the incumbents—as well as potential entrants in the long run—will generate economic profits is affected by a number of different kinds of equilibrium, such as Nash, Cournot, and the kinked demand curve.It is possible to start price wars to get weaker competitors to leave the market.
Market power measurement is challenging.It would be ideal to compute econometric estimates of the demand and supply elasticity.However, regulators and economists frequently employ simpler measures due to the absence of reliable data and the fact that elasticity changes over time (which means that previous data may not apply to the situation at hand).While the concentration ratio is straightforward, the HHI frequently yields a figure that is more useful for making decisions and does not necessitate as much computation.
