Where a tax increases linearly, the deadweight loss increases as the square of the tax increase. This means that when the size of a tax doubles, the base and height of the triangle double. Thus, doubling the tax increases the deadweight loss by a factor of 4. The varying deadweight loss from a tax also affects the government's total tax revenue.
A monopoly has considerable although not unlimited market power. A monopoly has the power to set prices or quantities although not both. [37] A monopoly is a price maker. [38] The monopoly is the market [39] and prices are set by the monopolist based on their circumstances and not the interaction of demand and supply. The two primary factors ...
[1] [2] A monopoly occurs when a firm lacks any viable competition and is the sole producer of the industry's product. [1] [2] Because a monopoly faces no competition, it has absolute market power and can set a price above the firm's marginal cost. [1] [2] The monopoly ensures a monopoly price exists when it establishes the quantity of the ...
The clearest example is a monopoly, where a single producer has complete control over supply and can extract a monopoly price. An oligopoly - a small number of producers - can also sustain an undersupply if no producers attempt to gain market share with lower prices at higher volume. Lack of supply competition can arise in many different ways:
Producer surplus, or producers' surplus, is the amount that producers benefit by selling at a market price that is higher than the least that they would be willing to sell for; this is roughly equal to profit (since producers are not normally willing to sell at a loss and are normally indifferent to selling at a break-even price).
The average cost of funds is the total cost of distortions divided by the total revenue collected by a government. In contrast, the marginal cost of funds (MCF) is the size of the distortion that accompanied the last unit of revenue raised (i.e. the rate of change of distortion with respect to revenue). In most cases, the MCF increases as the ...
Although a regulated monopoly will not have a monopoly profit that is high as it would be in an unregulated situation, it still can have an economic profit that is still above what a competitive firm has in a truly competitive market. [2] Government regulations of the price the monopoly can charge reduce the monopoly profit, but do not ...
Moreover, the sale does not occur, so the government never collects the revenue that was the whole reason for the distortion. This is the deadweight loss—the government has not merely taken a cut of the benefits from the exchange, it has destroyed those benefits for all three. [7] These are the results optimal tax theorists seek to avoid.
