Pollution in River Delta Investigated
An environmental organization has raised concerns about heavy pollution in the River Delta caused by nearby manufacturing plants. The river is contaminated with hazardous chemicals, making the water unsuitable for agriculture and drinking. Local fish populations have also been severely affected, leading to reduced income for fishermen.
Residents have reported increased cases of respiratory and waterborne diseases, blaming the pollution caused by factories. The government has been criticized for insufficient policies to address the issue, but it announced potential measures, including the introduction of indirect taxes, subsidies for cleaner technologies, and regulations limiting pollutant emissions. Additionally, there are proposals to establish a tradable permit system to reduce pollution levels.
Table 1: Economic Impact of Pollution in the River Delta
| Year | Total Fish Catch (tons) | Fishermen's Income (US$ million) | Agricultural Losses (US$ million) | Healthcare Costs Due to Pollution (US$ million) |
|---|---|---|---|---|
| 2018 | 1200 | 25.4 | 10.2 | 15.6 |
| 2021 | 950 | 18.7 | 14.5 | 22.3 |
| 2024 | 700 | 12.3 | 19.1 | 30.8 |
Table 2: Government Intervention Strategies
| Policy | Expected Cost (US$ million) | Projected Reduction in Pollution (%) | Potential GDP Impact (%) |
|---|---|---|---|
| Indirect Taxes | 50 | 30 | -0.5 |
| Subsidies for Cleaner Technology | 70 | 45 | 0.3 |
| Regulation on Emissions | 40 | 35 | -0.2 |
| Tradable Permits | 60 | 50 | 0.5 |
(i) Using information from the text and your knowledge of economics, evaluate the impact of government intervention in reducing pollution while promoting economic development.

Pollution in the River Delta is a clear example of a negative externality of production, where manufacturing plants impose external costs on third parties such as fishermen, farmers and local residents. In this case, the marginal social cost (MSC) of production is greater than the marginal private cost (MPC), so the ma
