The impact of subsidies A subsidy is a payment made to firms or consumers designed to encourage an increase in output. Figure 1 Impact of a subsidy The amount of the subsidy is shown by the gap between the supply curves.
Figure 2 Subsidy expenditure As with a tax see the previous section - click on the left arrow at the top or bottom of the page , some of the subsidy will benefit the consumer the amount of the price decrease and some will benefit the firm. Figure 3 Subsidy shares - producer and consumer. Copyright - Triple A Learning. The sellers gain area A in new producer surplus.
The buyers, who now pay a lower price, gain area B in consumer surplus. The subsidy thus costs C dollars more than the benefits it delivers. It is pareto inefficient, and area C is deadweight loss. If the supply of a good is inelastic, or doesn't change in response to a change in prices, this would mean that a subsidy program has no effect, and would become nothing more than a handout to the suppliers. If a supplier, such as a home builder couldn't increase its production any further, the supply curve would rise up steeply, and economists would call this an inelastic response to an increase in price.
A subsidy that affects the demand side would actually shift the entire curve from one position to another, such as moving to the right or left. This differs from the curve staying in one spot but new data points causing it to steepen, for example. A certain supply-price equilibrium exists on the chart, but this equilibrium would shift in the presence of a subsidy.
In the case of a demand-side subsidy, this would entail an increase in price rather than an increase in the number of available homes. This subsidy would then become an additional profit for the housing suppliers. A supply-side subsidy would attempt to reduce the price at which suppliers will provide a certain amount of houses, and this would affect the supply curve by causing it to shift sideways to a new chart location.
A new equilibrium would be established, and prices would decrease while the number of houses provided increases. Subsidies make sense in some situations, but not always. The tool can work well to provide a fix for problems in the market, such as when a private market doesn't deliver an outcome that works for society.
For example, subsidies can motivate companies to perform research and development in areas that would benefit society, even if it wouldn't necessarily be a large profit generator for the company. Subsidies can also provide much-needed help to startups that need to survive an initial period of financial losses until the business matures enough to become self-sustaining.
