Shanghai's Air Pollution: Impact And Insights

Shanghai is one of the most polluted cities in the world, with air quality that is almost four times worse than the World Health Organisation's guideline. Air pollution in Shanghai is largely caused by the wind blowing in toxic air from the industrialised areas to its west. This has a significant impact on the health of Shanghai's residents, as well as their consumption patterns and behaviours. For example, air pollution has been found to increase negative emotions, decrease outdoor activities, and depress future expectations. It also affects the stock market, with worsening air quality leading to a decline in stock prices and returns.

Air pollution increases medical expenses and reduces income savings

Air pollution in Shanghai, China, has far-reaching consequences, including impacts on the health and finances of its residents. The effects of air pollution on physical and mental health can result in increased medical expenses and reduced income savings for individuals.

Firstly, air pollution can lead to various health issues, including respiratory diseases, depression, and other physical and psychological problems. The treatment of these health conditions can result in higher medical costs for individuals, reducing their disposable income. For example, in 2017, China's economic loss due to premature deaths and hospitalizations related to air pollution was 2065 billion Yuan, equivalent to 2.5% of the country's GDP for that year.

Secondly, air pollution can cause people to take more sick leave, reducing their annual income. It also increases the likelihood of accidents and crimes, leading to additional economic burdens. As a result, individuals may have lower incomes and be less likely to invest in riskier assets like stocks.

Additionally, air pollution can affect investor sentiment and behaviour, impacting stock market performance. Investors may become more risk-averse due to negative emotions and increased concerns about health and safety. This can lead to reduced participation in the stock market and a preference for more stable financial products.

Furthermore, air pollution disproportionately affects medium and low-income households, creating a "Matthew Effect." These households experience a greater negative impact on their consumption patterns and structures due to air pollution.

Overall, air pollution in Shanghai increases medical expenses and reduces income savings for its residents, impacting their financial well-being and investment behaviours.

Air pollution can cause industrial policy adjustments, affecting the operational performance of listed firms

Air pollution has had a significant impact on Shanghai and the rest of China, with particulate matter, especially PM2.5, being the primary air pollutant in urban areas. The Chinese government has implemented various policies and plans to combat this issue, such as the Action Plan on Prevention and Control of Air Pollution and the Three-Year Action Plan for Blue Sky Defense. These initiatives aim to reduce PM2.5 and other air pollutants, with a particular focus on the greater Beijing-Tianjin-Hebei region and the Fenwei Plain.

Shanghai, as one of the key regions targeted by these policies, has felt the direct impact of these industrial policy adjustments. The city has set specific targets to improve its air quality, including reducing the average PM2.5 concentration and increasing the number of clear sky days. These targets have influenced the operational strategies of listed firms in the area.

The effects of air pollution on the operational performance of listed firms in Shanghai are twofold. Firstly, firms in industries such as heavy industry, coal-based power generation, and vehicle emissions have had to adjust their operations to comply with stricter emissions standards. This has likely involved investing in new technologies, changing production processes, and improving energy efficiency. These adjustments may have increased operational costs and disrupted established practices, potentially affecting the firms' financial performance and competitiveness.

Secondly, air pollution has influenced human capital and labour costs, which are essential factors in a firm's operational performance. Studies have shown that air pollution can negatively impact the health and productivity of employees, leading to increased absenteeism, reduced labour supply, and higher healthcare costs. Firms may need to provide additional benefits or compensation to retain and motivate their employees, impacting their operational costs and profitability.

Additionally, air pollution has been found to inhibit technological innovation, both at the regional and enterprise levels. This could affect the ability of listed firms to adapt to changing market demands, develop new products, and maintain their competitiveness in the long run.

Overall, air pollution has been a driving force for industrial policy adjustments in Shanghai, and these adjustments have had a direct impact on the operational performance of listed firms in the region. While the immediate effects may pose challenges, the long-term benefits of improved air quality are expected to positively impact the firms' sustainability and public perception.

Air pollution can cause negative emotions, decreasing outdoor activities and depressing future expectations

Air pollution in Shanghai is a pressing issue, with the city facing challenges from various sources, including factories, power plants, and agricultural activities. While real-time air quality data is available from multiple sources, it is important to understand the impact of air pollution on people's emotions, outdoor activities, and future expectations.

Impact on Negative Emotions

Air pollution has been linked to an increase in negative emotions such as annoyance, dissatisfaction, worry, and disgust. It can evoke unpleasant emotions, leading to a decrease in perceived interpersonal trust. People may become more indifferent and hostile towards others, impacting their social relationships and overall well-being. This can have long-term consequences for mental health and psychosocial adjustment.

Decreasing Outdoor Activities

The presence of air pollution can deter people from engaging in outdoor activities and exertion. Active individuals, especially those with respiratory conditions like asthma, are advised to limit their time spent outdoors when air pollution levels are high. This reduction in outdoor activities can further contribute to a decline in physical health and social interactions.

Depressing Future Expectations

Air pollution can also affect people's future expectations and outlook. High levels of air pollution are associated with increased negative emotions, which can influence people's perceptions of the future. Additionally, individuals with lower emotional susceptibility, who are more easily influenced by external factors, may experience decreased trust in others and a more pessimistic view of the future due to air pollution.

The effects of air pollution on emotions, outdoor activities, and future expectations are complex and interconnected. It is important to address these issues to improve the overall well-being and quality of life for residents in Shanghai and other areas affected by air pollution.

Air pollution can cause diseases, increasing people's medical expenses and reducing their income savings

Air pollution in Shanghai can cause a range of health issues, from respiratory diseases to cancer, and even death. These health issues can result in increased medical expenses for individuals, which can eat into their income savings.

Air pollution can increase the risk of respiratory diseases such as asthma, as well as other health problems such as depression. For example, in 2017, an estimated 1.24 million people died in China from exposure to air pollution. The harmful effects of air pollution on health can lead to increased medical expenses for individuals, reducing their income savings.

Additionally, air pollution can also have indirect effects on income savings. For instance, people may need to take more sick leave due to health issues caused by air pollution, resulting in a loss of income. Furthermore, air pollution can also increase the probability of accidents and crimes, leading to additional economic burdens. All these factors can contribute to a decrease in disposable income for individuals, affecting their economic activities and investment decisions.

The impact of air pollution on health and the subsequent increase in medical expenses can vary depending on individual factors such as income level and pre-existing health conditions. For example, people with higher incomes may be more concerned about health precautions and seek medical care more readily. On the other hand, those with lower incomes may delay seeking medical attention due to financial constraints, potentially worsening their health outcomes.

Furthermore, air pollution can also influence investment decisions and stock market performance. Investors' sentiments and behaviours can be affected by air pollution, leading to changes in stock prices and returns. For instance, investors may become more risk-averse due to concerns about their health and potential medical expenses, choosing to invest in less risky financial products.

Overall, air pollution in Shanghai has far-reaching consequences, including increased medical expenses and reduced income savings for individuals, as well as potential impacts on investment decisions and stock market performance.

Air pollution can cause accidents and crimes, increasing unnecessary economic burdens

Shanghai, like many cities, struggles with air pollution. While the specific effects of air pollution on Shanghai are not clear, we do know that air pollution can have a range of impacts on human health, the environment, and even social behaviour.

One of the most significant ways that air pollution can increase economic burdens is by causing or contributing to accidents and crimes. Poor air quality, particularly when fine particulate matter and ozone are present, is linked to an increased risk of violent criminal behaviour. Research from the University of Minnesota and Colorado State University found that breathing dirty air can make people more aggressive and impulsive, even after just a day of exposure. This can escalate everyday minor conflicts into serious physical altercations.

The University of Chicago analysed crimes reported to the Chicago Police Department between 2001 and 2012 and found that violent crimes, including homicide, rape, assault, and battery, rose by 2.2% in areas with temporarily increased local air pollution. They estimated that the cost of violent crime attributable to pollution in Chicago is over $81 million per year, with almost all of it due to homicide. If assaults and batteries are the only crimes considered, the cost is still a significant $1.8 million per year.

Additionally, air pollution can contribute to accidents by reducing visibility and causing health issues in vulnerable individuals. Wildfires, for example, are a significant source of air pollution and can be caused or intensified by human activities. The smoke from wildfires can spread over large areas, affecting air quality and causing respiratory issues. This can result in increased healthcare costs and economic burdens for the affected regions.

Furthermore, air pollution can also lead to technological accidents and infrastructure damage. For example, earthquakes can cause damage to petroleum storage facilities, leading to smoke and the release of pollutants. Similarly, floods can release pollutants such as methane and hydrogen sulphide, as well as increase the risk of infectious diseases due to water contamination. These accidents and infrastructure failures can have significant economic impacts, especially in developing nations.

Overall, the effects of air pollution on human behaviour and health can indirectly lead to accidents and crimes, resulting in unnecessary economic burdens for societies. These issues are complex and multifaceted, and addressing air pollution is crucial to mitigating these burdens.
