The government passes a law that allows a substantial subsidy for every acre of land use to grow tobacco. How does this program affect the long- run supply curve of tobacco?
The Correct Answer and Explanation is:
Correct Answer:
The long-run supply curve of tobacco shifts to the right.
Explanation:
When the government provides a substantial subsidy for each acre of land used to grow tobacco, it effectively reduces the cost of production for tobacco farmers. In economics, a subsidy acts like a negative tax—it gives money to producers, making the activity (in this case, growing tobacco) more profitable.
In the short run, some farmers may start reallocating land or resources to tobacco production to take advantage of the subsidy. However, the more significant effects occur in the long run, when all inputs are variable, and producers can enter or exit the market more freely.
Here’s what happens over the long run:
- Increased Profitability: The subsidy increases the expected profits from tobacco farming. As a result, more producers find it worthwhile to enter the tobacco industry, and existing producers may expand their operations.
- Market Entry: Because barriers to entry are usually lower in the long run, new farmers or companies will begin to grow tobacco, increasing total industry output.
- Rightward Supply Shift: As more producers enter the market and more land is allocated to tobacco farming, the overall supply of tobacco increases at every price level. This causes the long-run supply curve to shift to the right.
- Price Effects: If demand for tobacco remains unchanged, this increase in supply will eventually lead to lower market prices for tobacco. However, the continued existence of the subsidy may keep profit margins attractive, sustaining higher production levels than would exist without the subsidy.
- Efficiency and Resource Allocation: In the long run, resources like land, labor, and capital may be reallocated from other crops or industries into tobacco farming, potentially affecting the overall structure of the agricultural sector.
In summary, the subsidy encourages more production by making tobacco farming more lucrative, which increases the long-run quantity supplied and shifts the long-run supply curve to the right.
