In the Lindahl Model, Dt represents the aggregate marginal benefit curve, which is the sum of Da and Db---the marginal benefits for the two individuals in the economy. In a Lindahl equilibrium, the optimal quantity of the public good will be where the social marginal benefit intersects the marginal cost (point P).
A social optimum occurs when the nominal rate is zero (or deflation is at a rate equal to the real interest rate), so that the marginal social benefit and marginal social cost of holding money are equalized at zero. Thus, the Friedman rule is designed to remove an inefficiency, and by doing so, raise the mean of output.
In the previous example of the taxpayer with $60,000 in taxable income, only some of that income will be taxed at the marginal rate — or highest applicable rate — of 22%.
Managers can make business decisions on the output level based on this analysis in order to maximize the profit of the firm. Marginal Analysis is considered the one of the chief tools in managerial economics which involves comparison between marginal benefits and marginal costs to come up with optimal variable decisions.
When the marginal social interest diverges from the marginal private interest, the industrialist has no incentive to internalize the marginal social cost. Conversely, Pigou argues, if an industry produces a marginal social benefit, the individuals receiving the benefit have no incentive to pay for that service.
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 ...
The person hits a benefits cliff at the income of $31,000, losing several welfare benefits and tax credits, making their effective less than $50,000. At an earned income of $45,000, the person hits a bigger cliff, paying additional taxes while losing more benefits, taking the effective income below $40,000.
The price that consumer is willing to pay is same as the marginal utility of the consumer. Allocative Efficiency example . From the graph we can see that at the output of 40, the marginal cost of good is $6 while the price that consumer is willing to pay is $15. It means the marginal utility of the consumer is higher than the marginal cost.
