In the context of growing worldwide inequality, it is important to know what happens when the demand for low-skilled workers changes. Because natural resource shocks are global in nature, but have highly localized impacts on labor prospects in resource extraction areas, they offer a unique opportunity to evaluate low-skilled men's behavior when faced with extreme variations in local labor market conditions. This situation can be utilized to evaluate a broad range of outcomes, from education and income, to marital and fertility status, to voting behavior.

One of the primary considerations in policy debates related to energy development is the projected effect of resource extraction on local workers. These debates have become more common in recent years because technological progress has enabled the extraction of unconventional energy sources, such as shale gas and oil, spurring rapid development in many areas. It is thus crucial to discuss the empirical evidence on the effect of “energy booms” on local workers, considering both the potential short- and long-term impacts, and the implications of this evidence for public policy.

Climate change is rapidly deteriorating environmental conditions through droughts and floods, hurricanes, wildfires, rising temperatures, and more frequent and longer heatwaves. A growing literature has shown how higher temperatures reduce worker productivity and economic output. These effects are more pronounced in poorer countries and in climate-exposed economic sectors like agriculture, construction, and manufacturing. The development of new technologies that mitigate exposure to heat among workers, combined with better temperature control in the workplace, will be essential to reduce the economic burden of climate change.

New environmental technologies (environmental/eco-innovations) are often regarded as potential job creators—in addition to their positive effects on the environment. Environmental regulation may induce innovations that are accompanied by positive growth and employment effects. Recent empirical analyses show that the introduction of cleaner process innovations, rather than product-based ones, may also lead to higher employment. The rationale is that cleaner technologies lead to cost savings, which helps to improve firms’ competitiveness, thereby inducing positive effects on their market shares.

Environmental regulations such as air quality standards can lead to notable improvements in ambient air quality and to related health benefits. But they impose additional production costs on firms and may reduce productivity, earnings, and employment, especially in sectors exposed to trade and intensive in labor and energy. Growing empirical evidence suggests that the benefits are likely to outweigh the costs.

Environmental regulations raise production costs at regulated firms, though in most cases the costs are only a small fraction of a firm’s total costs. Productivity tends to fall, and firms may shift new investment and production to locations with less stringent regulation. However, environmental regulations have had enormous benefits in terms of lives saved and illnesses averted, especially through reductions in airborne particulates. The potential health gains may be even greater in developing countries, where pollution levels are high. The benefits to society from environmental regulation hence appear to be much larger than the costs of compliance.

Many industrial countries are pursuing so-called green energy policies, which typically imply the replacement of conventional fossil fuel power plants with renewable sources. Such a policy shift may affect employment in different ways. On the one hand, it could create new and additional “green jobs” in the renewables sector; on the other hand, it could crowd out employment in other sectors. An additional consideration is the potential increase in energy prices, which has the potential to stifle labor demand in energy-intensive sectors and reduce the purchasing power of private households.

Extreme weather events are increasing in frequency and intensity, threatening lives and livelihoods around the world. Understanding the short- and long-term effects of such events is necessary for crafting optimal policy. The short-term economic impacts of natural disasters can be severe, suggesting that policies that better insure against consumption losses during this time would be beneficial. Longer-term economic impacts are more complex and depend on the characteristics of the affected population and the affected area, changes in migration patterns, and public policy.

Research finds that hot weather causes a fall in birth rates nine months later. Evidence suggests that this decline in births is due to hot weather harming reproductive health around the time of conception. Birth rates only partially rebound after the initial decline. Moreover, the rebound shifts births toward summer months, harming infant health by increasing third trimester exposure to hot weather. Worse infant health raises health care costs in the short term as well as reducing labor productivity in the longer term, possibly due to lasting physiological harm from the early life injury.

Survey and register data indicate that many employees prefer a socially responsible employer and will accept a lower wage to achieve this. Laboratory experiments support the hypothesis that socially responsible groups are more productive than others, partly because they attract cooperative types, partly because initial cooperation is reinforced by group dynamics. Overall, the findings indicate corporate social responsibility may have cost advantages for firms.
