The lost consumer surplus plus the lost producer surplus is the total deadweight loss to society. Graph 7. The blue rectangle is the amount transferred to the monopolist from the consumers. By operating at the monopolist output, the monopolist captures some consumer surplus. Since the monopolist gains the blue rectangle, it is not part of the deadweight loss to society.
Although the monopolist lost some producer surplus red area in graph 6 , the transfer to him blue rectangle is greater than the loss, therefore, he ends up better off. Graph 1 The red triangle in the above graph represents producer surplus. Graph 2 The yellow triangle in the above graph represents consumer surplus.
Graph 3 Graph 3 combines producer surplus and consumer surplus into one graph. Graph 4 Graph 4 shows the areas of producer surplus and consumer surplus with a downward sloping demand curve. Graph 5 The monopolist produces where marginal cost equals marginal revenue.
Looking at Figure 3. Whereas consumer surplus is the difference between what the consumer is willing to pay and the price they pay, producer surplus is the difference between what the producer is paid revenue , and the variable cost of production. Our variable costs are represented by our implicit and explicit costs.
As we will explore later in the course, there is a key distinction between economic profit and the classic profit calculated in accounting. Accounting profit, on the other hand, does not include opportunity costs.
Economic profit subtracts fixed costs, whereas producer surplus does not. We will explore fixed costs in depth soon. The problem is simple.
On the graph, this always corresponds to a rectangle bounded by the price and the quantity supplied the blue shaded region.
To find total variable cost we need to add the MC at each level, calculating the area under the supply curve the red shaded region. The calculation of cost for Figure 3. Bringing all this information together we can calculate producer surplus.
This corresponds to the area between the price producers receive, and their costs, shown in green in Figure 3. Determining producer surplus with changing prices closely mirrors that of consumer surplus during changing prices, but in order to get comfortable with the terminology, we will analyze the effects separately.
According to the law of supply, we know this decrease in price will cause a decrease in quantity supplied, but how does our producer surplus change? Calculating the change in the green area in Figure 3. This change is due to two factors. The last step we have in the derivation of supply is recognizing that there is divisibility of goods.
In the stair-step example, we are implicitly assuming that we can only trade cupcakes and cookies in 5 cupcake increments. Of course, this is not actually the case. Description: Institutional investment is defined to be the investment done by institutions or organizations such as banks, insurance companies, mutual fund houses, etc in the financial or real assets of a country. Simply state. Marginal standing facility MSF is a window for banks to borrow from the Reserve Bank of India in an emergency situation when inter-bank liquidity dries up completely.
Description: Banks borrow from the central bank by pledging government securities at a rate higher than the repo rate under liquidity adjustment facility or LAF in short. The MSF rate is pegged basis points or a percentage. Description: If the prices of goods and services do not include the cost of negative externalities or the cost of harmful effects they have on the environment, people might misuse them and use them in large quantities without thinking about their ill effects on the env.
