There is ample evidence of the negative effects of pollution on health, with about one in six deaths worldwide attributed to air pollution. However, the effect of one firm’s toxic emissions on neighbouring firms’ employees and profits are not known. This column examines whether opening toxic pollution-emitting plants affect the career paths of executives at S&P 1500 firms in the US. The opening of such plants triggers substantial increases in executive migration from neighbouring firms. Corporations exposed to toxic emissions from other firms lose talented individuals and suffer stock-price declines.

During 2013–2014, China launched a nationwide, real-time air quality monitoring and disclosure programme which substantially expanded public access to pollution information. This column analyses the impact of the programme and finds that it triggered a cascade of changes in household behaviour, prompting people to find out more online about pollution-related topics, adjust their day-to-day consumption to avoid exposure to pollution, and exhibit a higher willingness to pay for housing in less-polluted areas. The programme’s estimated annual health benefits far outweigh the combined costs of the programme and associated pollution-avoidance behaviours.

There is evidence that hot climatic temperatures and crime are linked. With climate change raising temperatures around the world, it is possible we may see higher levels of personal aggression. Based on data from Russia, this column shows that on hotter days, women are more likely to be killed in homicides, especially over weekends. Colder days have no similar effect on violence. Lower wages and higher unemployment contribute to higher homicide rates, so policies promoting employment may mitigate victimisation during extreme temperature days.

We think about climate policies as moderating or interceding in markets. 
But a new paper implies that when stock markets play a bigger part in the economy, polluting industries become cleaner. Tim Phillips asks Ralph De Haas of the European Bank for Reconstruction and Development whether we already have a green finance initiative under our noses.

The Trump administration recently repealed the US Clean Water Rule, which sought to extend federal water quality protection to cover most rivers and streams. This column seeks to better understand the effectiveness of such laws that govern US surface and drinking water quality, the efficiency of these laws, and the state of economic research on water quality. It finds that regulations governing surface water quality are more likely to fail cost-benefit tests compared to drinking water and air pollution regulations, possibly due to an underestimation of the benefits of surface water pollution control.

Economists argue whether foreign direct investment in developing economies exports pollution or generates green growth. Beata Javorcik talks to Tim Phillips about a surprising conclusion from factory-level research.

The link between foreign ownership and environmental performance remains a controversial issue. Data from the Indonesian manufacturing census show that plants undergoing foreign acquisitions reduce their energy intensity by about 30% two years after acquisition by multinationals. This column argues that foreign direct investment can serve as a channel for the international transfer of environmentally friendly technologies and practices, thus directly contributing not only to economic growth but also to environmental progress.

As climate change worsens and the forces of populism gather, there is a strong argument for moving beyond narrow economic measures of national progress. This column presents a new indicator of progress that integrates environmental, social, and governance factors into growth analysis. Results show that the countries that have been able to blend economic dynamism with environmental, social, and governance dynamism are mostly developing economies. These countries often fly under the radar of traditional macroeconomic analyses.

Many argue that the $1 trillion cost of the 1972 US Clean Water Act outweigh its benefits. The column uses new evidence on grants and water pollution readings to measure its impact. While the Act has decreased US water pollution, the estimated change in home values caused by this has been only one quarter of the grant costs, although this probably understates the full impact of the Act. The analysis suggests that targeting water pollution in more populous areas would improve net social benefits.

In the 2015 Paris Agreement, participating countries committed to trying to limit the increase in the global temperature to no more than 2 degrees, requiring a major transition in the way we produce products and services. Ralph de Haas explains his research on how this Green Transition can be financed, and whether certain types of finance - in particular stock vs. credit markets - are better suited to achieving 'greener growth'. This video was recorded at CEPR's Third Annual Spring Symposium.

Europe currently faces multiple challenges on economic, demographic, and environmental fronts. All of these can be addressed by innovations in technology and process. This video discusses some of the outcomes of the EU-FRAME mid-term conference, outlining ways in which innovation policy can be designed so as to best serve welfare and productivity across all actors. This conference took place in March 2018 at ZEW, Mannheim.

CEPR is a partner of the FRAME Project, which is coordinated by ZEW. The CEPR team is led by Diego Comin, a Research Fellow in its Macroeconomics and Growth Programme. The FRAME project has received funding from the European Union's Horizon 2020 Research and Innovation Programme under the grant agreement No #727073.

Traditional climate economics models recommend capturing the cheapest opportunities to reduce emissions first and keeping the most difficult options for later. This column argues that when the fact that reducing emissions takes time and requires investments in long-lived goods and assets is taken into account, the most cost efficient strategy overall is to act immediately in the sectors that are the most expensive and difficult to decarbonise, even if this means investing in options that have a higher cost right now than available alternatives. Actions on urban planning and urban transport systems are especially urgent.

Should countries keep extracting natural resources? In this video, Ruth Greenspan Bell discusses the challenge of promoting development while protecting the environment. This video was recorded at UNU-WIDER in May 2016.

Substantial headway has been made in the transition to clean technology, but recent political developments threaten this progress. This column examines the transition process using a microeconomic model of competition in production and innovation between clean and dirty technologies. The results suggest that production taxes can deal with dirty emission externalities, while research subsidies are sufficient to redirect innovation towards clean technologies. However, delaying intervention will drastically slow down the overall transition.

The ‘curse’ of natural resources on economic development has been well documented, but there is no consensus on its underlying causes. Exploiting the formation of new Indian states in 2001, this column shows that the effects of state breakup on local economies differ systematically across natural resource-rich and resource-poor areas, in line with the spatial distribution of natural resources within states. The relationship between resource abundance and economic outcomes flows, at least in part, through a political channel.

The health effects of pollution in terms of hospitalisations, mortality and morbidity are well researched, but not so much is known about the less severe effects of pollution on workers’ health. This column uses evidence from China to analyse the impact of pollution on productivity, finding that high levels of pollution reduce the productivity even of indoor workers. Reducing pollution is not just welfare-improving for society, it is also of financial benefit to the economy.

At the the Paris Climate Conference in December 2015, it was agreed that annual global temperature increase must be kept below 2 degrees, and a target of a 1.5 degree annual increase was set. Most environmental policies currently focus on emissions reductions and adaptation. This column discusses a new set of technologies collectively known as climate engineering, and explores their potential effectiveness and role in climate change economics. A lot of uncertainty surrounds the costs and effects of climate engineering tools, but it is clear that they would change the optimal levels of emissions reduction currently discussed in literature.

Across the world, 650 million people still lack access to clean water, despite great progress over last two decades. This column looks at the case of Bangladesh, where around 45 million people are at risk from drinking water that is contaminated with naturally occurring arsenic. Drinking this water can lead to symptoms of arsenicosis, which have a significant negative impact on mental health and thus on household productivity and wellbeing.

Pollution levels are orders of magnitude higher in lower-income countries than in the developed world. This means that studies of the health effects of pollution based on data from the latter will not necessarily be relevant to the former. This column reports on the effect of air pollution on infant mortality in Mexico City. Significant effects are found that are much larger than found in earlier work based on US data. These findings highlight the potential pitfalls of naively extrapolating findings from high-income to developing countries.
