The marginal revenue curve is affected by the same factors as the demand curve – changes in income, changes in the prices of complements and substitutes, changes in populations, etc. [15] These factors can cause the MR curve to shift and rotate. [16] Marginal revenue curve differs under perfect competition and imperfect competition (monopoly ...
In economics, the Laffer curve illustrates a theoretical relationship between rates of taxation and the resulting levels of the government's tax revenue. The Laffer curve assumes that no tax revenue is raised at the extreme tax rates of 0% and 100%, meaning that there is a tax rate between 0% and 100% that maximizes government tax revenue. [a ...
Maximum total revenue is achieved where the elasticity of demand is 1. The above movements along the demand curve result from changes in supply: When demand is inelastic, an increase in supply will lead to a decrease in total revenue while a decrease in supply will lead to an increase in total revenue.
The company maximises its profits and produces a quantity where the company's marginal revenue (MR) is equal to its marginal cost (MC). The company is able to collect a price based on the average revenue (AR) curve. The difference between the company's average revenue and average cost, multiplied by the quantity sold (Qs), gives the total profit.
The break-even points (A,B,C) are the points of intersection between the total cost curve (TC) and a total revenue curve (R1, R2, or R3). The break-even quantity at each selling price can be read off the horizontal axis and the break-even price at each selling price can be read off the vertical axis.
In perfectly competitive markets the demand curve, the average revenue curve, and the marginal revenue curve all coincide and are horizontal at the market-given price. [11] The demand curve is perfectly elastic and coincides with the average and marginal revenue curves. Economic actors are price-takers.
The Laffer curve embodies a postulate of supply-side economics: that tax rates and tax revenues are distinct, with government tax revenues the same at a 100% tax rate as they are at a 0% tax rate and maximum revenue somewhere in between these two values. Supply-siders argued that in a high tax rate environment lowering tax rates would result in ...
The marginal revenue function is the first derivative of the total revenue function or MR = 120 - Q. Note that in this linear example the MR function has the same y-intercept as the inverse demand function, the x-intercept of the MR function is one-half the value of the demand function, and the slope of the MR function is twice that of the ...
