What to Keep. After all creditors, taxing authorities and beneficiaries of the estate have been paid, the estate may be closed. How long the process of closing an estate will take varies from case to case. Generally, anyone making a claim against the estate must do so within a specified time frame.
Consumer surplus (Graph illustrating consumer (red) and producer (blue) surpluses on a supply and demand chart) Consumer surplus or Consumer's surplus (or in the plural Consumers' surplus) is the difference between the price consumers are willing to pay (or reservation price) and the actual price. If someone is willing to pay more than the actual price, their benefit in a transaction is how much they saved when they didn't pay that price.
But perfectly competitive markets are not necessarily productively efficient as output will not always occur where marginal cost is equal to average cost (MC = AC). In perfect competition, any profit-maximizing producer faces a market price equal to its marginal cost (P = MC). This implies that a factor's price equals the factor's marginal revenue product. It allows for derivation of the supply curve on which the neoclassical approach is based.
