This paper examines the application of quasi-experimental methods in environmental economics. We begin with two observations: (i) standard quasi-experimental methods, first applied in other microeconomic fields, typically assume unit-level treatments that do not spill over across units; (ii)...

This study provides a comprehensive assessment of firms' operation and environmental protection polices in Nigeria and Ghana, where there has been a rising industrial growth amidst low regulatory and institutional frameworks. We analyze the extents to whic h firms' adoption of environmental...

This paper analyzes the effect of financial constraints on firms' corporate social responsibility. Exploiting heterogeneity in firms' exposure to a monetary policy shock in the U.S., which reduced financial constraints for some firms, I find that firms increase their environmental...

In cities around the world, Covid-19 lockdowns have improved outdoor air quality, in some cases dramatically. Even if only temporary, these improvements could have longer-lasting effects on policy by making chronic air pollution more salient and boosting political pressure for change. To that...

In this study, a basic comparison between the Pigouvian and the Coasean approaches is carried out in order to discuss and comment on the mechanisms by which externalities are resolved. Environmental control approaches are examined and compared in terms of minimization of abatement costs,...

As in numerous big cities in developing countries, environmental problems in Cotonou are becoming more and more severe. These problems are the result, among other factors, of the strong air pollution by the motorbike transport sector. This study, while considering health expenditures due to air...

Axbard and Deng (2024) exploit the rollout of new pollution monitors in China in 2015 in 177 medium-size cities to study the effect of air-quality monitors on enforcement actions by local governments and air quality. In their main difference-in-difference analysis, they identify the change in...

On a theoretical front, environmental economists have one last pollution problem to contend with and that is the issue of non-point source pollution (NPSP). The issue of NPSP is important on many levels but central to this field is how to efficiently regulate what you cannot observe? A promising...
