The pollution haven hypothesis describes how companies move their polluting activities to countries with less stringent environmental regulations, leading to an unequal distribution of environmental degradation across the world. This is often driven by the higher costs of production in countries with stricter environmental policies, which incentivises companies to relocate to countries with lower environmental standards or weaker enforcement. The environmental Kuznets curve (EKC) is a conceptual model that reflects this hypothesis, suggesting that a country's pollution concentrations rise with industrialisation until increased affluence allows for a reduction in pollution concentrations. This model suggests that the cleaner environment in developed countries may come at the expense of increased environmental degradation in developing countries.

What You'll Learn
The Pollution Haven Hypothesis
The PHH identifies two critical factors: foreign direct investment (FDI) and environmental laws. FDI is a crucial aspect of open and effective international economic processes and is a significant catalyst for the economic development, income growth, and employment of emerging economies. The hypothesis suggests that the movement of polluting industries from advanced to developing countries occurs through the trade of commodities and FDI.
According to the PHH, the severity of environmental laws in host countries encourages investment in emission-intensive industries from developed countries. The easy environmental rules in developing countries make it more attractive for foreign companies to relocate their factories to these regions, allowing them to save money on waste disposal and labour. This results in an increase in economic activity (Y) and a negative impact on regulatory stringency (R). Analysts can use this equation to calculate the expected effect on economic activity by altering the value of R.
While the PHH has some empirical support, its overall significance relative to other investment and trade factors remains controversial. Studies have found evidence supporting the hypothesis, particularly in the context of countries with poor air quality having higher net factor exports of coal. However, the impact is relatively small compared to other variables. Additionally, the environmental standards of host countries and the pollution intensity of multinational corporations can be challenging to measure accurately.

Environmental Kuznets Curve (EKC)
A pollution haven is a country that receives foreign toxic waste or pollutants as a result of another country's strict environmental regulations and the high costs of reducing pollution domestically. The concept of a pollution haven is often associated with the Environmental Kuznets Curve (EKC) hypothesis, which suggests that as an economy develops, it goes through stages of increasing and then decreasing environmental degradation.
The EKC hypothesis suggests that in the early stages of economic development, industrialization, and urbanization, pollution and environmental degradation tend to increase. This is because the priority during these stages is often placed on economic growth, and the environment is often a lower priority. As a result, the pollution levels in the atmosphere, water bodies, and land can rise sharply.
However, as per the EKC hypothesis, beyond a certain stage of economic development, a country's pollution levels tend to stabilize and eventually decrease. This decrease is attributed to several factors. Firstly, as countries become more affluent, they can afford to allocate resources towards environmental protection and cleaner technologies. Secondly, public awareness and demands for a cleaner environment increase, putting pressure on governments and industries to adopt more sustainable practices. Additionally, at higher income levels, the nature of economic activity shifts from heavy industry to services and high-tech industries, which are less polluting.
The EKC hypothesis suggests that there is an inverted U-shaped relationship between environmental degradation and income per capita. This implies that once a country reaches a certain level of economic development, it may become a "cleaner" country, potentially offsetting the pollution generated during its earlier development stages. However, it's important to note that the EKC hypothesis is not without criticism and controversy. Empirical evidence supporting the EKC varies across studies, and some argue that the relationship may not hold true for all types of pollution or across all countries.
In the context of pollution havens and the EKC, developing countries with lax environmental regulations and low costs may attract pollution-intensive industries from developed countries. This can result in these developing countries becoming pollution havens, experiencing high levels of pollution and environmental degradation. However, over time, as these havens undergo economic development, they may follow the EKC curve and eventually reduce their pollution levels. This transition could be influenced by factors such as international pressure, technological advancements, or a shift in public priorities demanding better environmental standards.
It is worth noting that the EKC hypothesis serves as a theoretical framework and may not perfectly align with the complex dynamics of pollution and economic development. Nonetheless, it provides valuable insights into the potential relationship between environmental degradation and economic growth, offering a perspective on the evolution of pollution havens.

Endogenous environmental policy
Pollution havens, also known as the pollution haven hypothesis, refer to the concept of large industrialised nations seeking to set up factories or offices abroad in countries with the cheapest resources and labour. However, this often comes at the cost of environmentally unsound practices. Developing nations with cheap resources and labour tend to have less stringent environmental regulations, and companies that invest in foreign countries often relocate to countries with the lowest environmental standards.
The validity of empirical tests of the Pollution Haven Hypothesis (PHH) has been questioned due to issues of unobserved heterogeneity and measurement errors in environmental regulation. Recent literature has emphasised the importance of geographic spillovers in determining the location choice of foreign investment, but these spatial effects have not been adequately incorporated into empirical tests.
Some studies have found that environmental regulations have a strong negative effect on a country's FDI, particularly in pollution-intensive industries when measured by employment. However, neighbouring countries' environmental regulations do not seem to have a significant impact on trade flows.
The role of government corruptibility has also been explored, with findings suggesting that when corruptibility is high, foreign direct investment may create pollution havens, whereas when it is low, pollution damage may decline despite increased economic output.
In conclusion, endogenous environmental policy is a critical aspect of understanding pollution havens. It highlights the complex interplay between environmental regulations, economic activity, and foreign investment, with potential consequences for pollution levels and environmental degradation.

Foreign investment and trade
The pollution haven hypothesis suggests that large industrialised nations seeking to establish factories or offices abroad will often opt for locations with the cheapest resources and labour, which typically coincides with a lack of stringent environmental regulations. This dynamic results in the relocation of polluting industries to developing nations with more lax environmental standards.
For example, following stricter air quality standards for lead pollution implemented by the US Environmental Protection Agency in 2009, American companies began exporting used lead-acid batteries to Mexico, where environmental officials acknowledged their limited capacity to regulate the influx. This resulted in a significant increase in babies born with low birth weight to mothers living near Mexican battery-recycling plants.
The environmental Kuznets curve (EKC) is a conceptual model that lends support to the pollution haven hypothesis. The EKC suggests that a country's pollution levels rise with industrialisation and development until a turning point is reached, after which they decrease as the country gains the financial means to reduce pollution concentrations. The EKC implies that the cleaner environment enjoyed by developed countries may come at the expense of increased environmental degradation in developing countries, as polluting industries are transferred abroad through foreign investment and trade.
However, it is important to note that the relationship between foreign investment, trade, and pollution havens is complex and challenging to quantify. Measuring the regulatory stringency of different jurisdictions and the indirect effects of trade liberalisation on pollution havens is a significant obstacle in fully understanding this relationship.

Environmental regulation and enforcement
The Pollution Haven Hypothesis (PHH) suggests that large industrialised nations seeking to establish factories or offices abroad will often opt for locations with the cheapest resources and labour, despite environmentally unsound practices. This hypothesis is supported by the Environmental Kuznets Curve (EKC), which indicates that pollution concentrations increase with development and industrialisation until a turning point is reached, after which concentrations decrease as the country can now afford to reduce pollution.
Developing nations with inexpensive resources and labour tend to have less stringent environmental regulations, making it more affordable for companies to operate there. Conversely, nations with stricter environmental regulations become costlier for businesses due to the expenses associated with meeting these standards. As a result, companies tend to relocate to countries with the lowest environmental standards or weakest enforcement, leading to the emergence of pollution havens.
For example, in 2009, the Environmental Protection Agency in the United States tightened National Ambient Air Quality Standards for lead pollution, making domestic recycling more challenging and expensive. Consequently, exports of used lead-acid batteries to Mexico increased significantly, with Mexican environmental officials acknowledging their lack of resources to effectively monitor and control this influx. This scenario exemplifies how stricter environmental regulations in one country can inadvertently lead to the creation of a pollution haven in another.
The identification and quantification of pollution havens are complex tasks due to the dynamic nature of economic and environmental factors. Models such as the dynamic H-O model and the factor endowment hypothesis are employed to analyse the relationship between international trade, the environment, and endogenous environmental policies. These models consider factors such as income levels, labour abundance, capital abundance, and technology, which collectively influence the emergence of pollution havens.
While GDP PPP per capita may not be a perfect indicator, e-waste dump sites in pre-industrial nations provide some support for the PHH. For instance, Guiyu, China, became a hub for electronic waste processing, attracting waste from developed countries due to its lack of environmental regulations and affordable labour. This resulted in significant environmental contamination, with lead levels in water samples far exceeding safe levels.
