With the help of a diagram(s), explain what is meant by consumer surplus and producer surplus and consider whether a rise in the price of a product because of higher costs of production is likely to always reduce the consumer surplus. [8]

Consumer surplus is the difference between the maximum price an individual is prepared to pay for a good and the price actually paid. In the diagram above, the market price is at P with quantity at Q, hence the consumer surplus is indicated by the area under the demand curve and above the market price line (area AOP).

While producer surplus is the difference between the minimum price a supplier is willing to accept for a good and the price actually paid. Using the diagram above, the producer surplus is the area under the market price and above the supply curve (area POB).

When there is a rise in the price of a product due to higher costs of production, there is likely a reduce in the consumer surplus. This is most likely because the producers don’t want to bear the burden of the increase in price, so they will put it at the price for the consumers instead to pay. For example, a manufacturing company wants to buy more machines to help produce more goods hence will lead to an increase in the costs of production. To cover the company’s costs, they will raise the price of their goods.

Another example is when in the agriculture market, the government enforces an action to support farmers’ incomes by raising the price of the product above the market-clearing level, causing an increase in the labour costs of production The diagram above represents the reduce in the consumer surplus by looking at from area TWX to area TUV.

An economy is experiencing a fall in average incomes during a severe recession. Discuss the extent to which the concepts of income elasticity of demand and price elasticity of demand might be useful to an entrepreneur in this economy and consider which would be more useful. [12]

Assess whether the concept of price elasticity of supply or cross elasticity of demand will be more useful to a business wanting to increase its total sales in a growing economy. [12]

Income Elasticity of demand is a measure of the responsiveness of quantity demanded for a good following a change in the income, other things being equal.

Price elasticity of demand is a measure of the responsiveness of quantity demanded for a good following a change in the price of the good, other things being equal.

The concepts of income elasticity of demand is useful to an entrepreneur is it can help them to decide which goods they should produce and stock up on. In this case, as the economy is facing a severe recession causing a fall in the average incomes, entrepreneurs can focus on diverting their resources into production and increasing the stocks of inferior goods and less on luxuries, as consumer spending is now limited. They can also focus on promoting more on inferior goods as they would be more sought after.

Another way the concept of YED is useful is it can help entrepreneurs to decide which goods to decrease its price following a fall in income. Hence, if the YED is positive and income is falling, the quantity demand for the good will also fall, the entrepreneurs might want to reduce its price to compensate for the fall in demand for the good.

While the concept of PED is useful to entrepreneurs as it helps to see the proportion of income spent on the commodity. When the proportion of income spent on a good is small, demand tend to be price inelastic as it has little impact on the quantity demanded following a price change. For example, salt, as people do not usually buy salt, consumers are not as sensitive if there is a change in the price.

This can also help entrepreneurs to increase or decrease the price of luxuries or necessities. Demand for luxuries tend to be price elastic, which is a big response to a small change in price, because we could manage without them. Hence, if the economy is facing a severe recession, demand for luxuries will decrease. However, demand for necessities is price inelastic because we need these goods to survive, so when there is a fall in income, lessening consumer spending, entrepreneurs can decrease the price of the goods so there is an increase in quantity demanded.

In my opinion, YED is more useful to entrepreneurs than PED because it can predict and make long-term strategic decisions.
