Climate and fiscal policy interact closely. The former imposes explicit prices for carbon emissions, while the latter affects emissions implicitly. We study the correspondence between explicit and implicit carbon pricing of a Ramsey-optimal fiscal policy in a neoclassical growth model of climate change. Our central result is that any arbitrary sequence of explicit carbon prices can be achieved implicitly through a blend of conventional taxes (e.g., consumption, energy, and income taxes), when lump-sum transfers are available. In a Ramsey setting, policy balances these taxes’ traditional revenue-raising role with the Pigouvian role of fixing the climate externality. We characterize the Ramsey and Pigouvian components of optimal tax rates. We show that explicit carbon pricing is implicitly implementable through a mix of conventional taxes also in this framework. We extend these findings to scenarios compatible with net-zero emissions, adding carbon capture technologies and a cap on cumulative emissions.

Open defecation has been linked to various environmental and public health issues and has gained significant policy attention. Investing in better sanitation has also been advocated to provide women with privacy and protection from harassment. Nonetheless, previous research has shown that because of son-biased preferences, households in India underinvest in outcomes for their female children. Linking the gender composition of children to the sanitation behavior in Indian households, I find that households increase toilet ownership in the presence of female children by 5% in urban and 2.5% in rural areas, respectively. These results are robust to various empirical specifications, falsification tests, and bounding analysis to test for omitted-variable bias. Various heterogeneity analyses suggest that the decline in open defecation in response to having a female child is driven by households living in regions with a higher prevalence gender-based harassment and weaker law and order. These findings provide new evidence that differences in the gender composition of households create differential incentives to adopt toilets, which can be harnessed to reduce open defecation in India.

We study the effects of in utero exposure to climate change induced high ocean salinity levels on children's anthropometric outcomes. Leveraging six geo-referenced waves of the Bangladesh Demographic and Health Surveys merged with gridded data on ocean salinity, ocean chemistry and weather indicators (temperature, rainfall and humidity) from 1993 to 2018, we find that a one standard deviation increase in in utero salinity exposure leads to a 0.11 standard deviation decline in height-for-age. Effects on weight-for-height and weight-for-age for a similar magnitude increase in salinity are 0.13 and 0.15 standard deviations, respectively. Analyses of parental investments and health-seeking behaviors demonstrate that compensating actions along these dimensions to attenuate the detrimental effects of salinity are few and restricted to poorer households. Using satellite-sourced datasets on agriculture and land-use, we find that increasing salinity constrains farmers' land use choices, restricting cultivation in the more profitable seasons which leads to lower agricultural potential. In particular, the effects of salinity on child health originate in areas with lower agricultural intensity caused by the progressive salinization of productive lands. These results highlight the climate change related costs of environmental insults on early-life health outcomes in vulnerable populations.

Environmentally friendly alternatives (EFA) are touted as a key component of a transition towards lowering the impact of human activity on the environment. Still, the environmental costs of these technologies are seldom null; they are simply less environmentally damaging than existing options. In this paper, we investigate consumer behavior when an EFA is introduced. Using a carefully constructed field experimental design, we look at plastic bags vis-a-vis biodegradable (bio) bags, when the latter are offered for free versus at a price. Moreover, we explore offering costly biodegradable bags as part of the default choice. We find that giving away the bio bags for free results in a large behavioral rebound effect, resulting in a substantial increase in the total number of bags. Setting a small, rather symbolic price offsets this rebound effect completely. Interestingly, when the bio bag is offered as a default, the behavioral rebound remains. Our results lead us to conclude against providing these EFA for free and to caution against the use of subsidies to promote their uptake.

We analyze welfare effects of trade in renewable resources, which is induced by consumer love of variety in resource consumption. We model two countries, one being relatively wealthy in labor and capital, the other one being relatively resource abundant. For open-access resources, we show that trade freeness benefits the country that is wealthy in labor and capital, as it improves access to a larger variety of resources, especially to those of the resource-abundant country. The resource-abundant country also benefits from improved access to variety, but due to the increased resource demand and resulting overuse, this country’s welfare may depend on trade freeness in a non-monotonic fashion. We derive conditions such that welfare first decreases and then increases when trade freeness varies from autarky to costless trade. In direct comparison, autarky may generate higher welfare than costless trade only under restrictive conditions, in particular if endowments are very asymmetric and if the love of variety effect is weak. We also consider resource harvesting under private property rights and show that only for a sufficiently low discount rate the welfare increase from trade freeness in the resource-abundant country is sustainable.

In the game-theoretical literature on forming international environmental agreements (IEAs) countries use to be self-interested materialists and stable coalitions are small. This paper analyzes IEA games with identical countries that exhibit Kantian moral behavior. Kantians are concerned with doing the right thing which means that they take those actions and only those actions that they advocate all others take as well. Countries may behave morally with respect to both emissions (reduction) and membership in an IEA. If countries are emissions Kantians or membership Kantians the equilibrium of the IEA games is socially optimal. To model more realistic Kantian behavior, we define an emissions [membership] moralist as a country whose welfare is a weighted average of the welfare of an emissions [membership] Kantian and a materialist. The game with emissions moralists produces stable coalitions not larger than those in the standard game with materialists. The game with membership moralists yields stable coalitions that are increasing in the membership morality. The aggregate emissions decline if the degree of morality of either type of moralists increases. Finally, we characterize the equilibrium of an IEA game with moderate moralists with respect to both emissions and membership.

We provide evidence of a substantial impact of pollution in the vicinity of a school on student learning using standardized test results from the universe of Tehran junior schools. The 2010 US sanctions prevented the sale of refined petroleum products to Iran. Causal identification exploits that the impact of sanctions on air quality in the vicinity of schools in the city varied according to the proximity of each school to roads. Relative academic performance dropped at more road-exposed (variously-measured) schools. Roads upwind appear to have four times the impact compared to those downwind, aligning with the prevailing wind direction which blows 80% of the time from the west, a finding that also provides compelling evidence against alternative interpretations.

In Bangladesh, cholera poses a significant environmental health risk. Yet, information about the severity of cholera risk is limited as risk varies over time and changing weather patterns make historical cholera risk predictions less reliable. In this paper, we examine how households use geographically and temporally personalized cholera risk predictions to inform their beliefs and behaviors related to cholera and its aversion. We estimate how access to a smartphone application containing monthly cholera risk predictions unique to a user’s home location affects households’ beliefs about their cholera risk and their water use and hygiene behaviors. We find that households with access to this application feel more equipped to respond to environmental and health risks and reduce their reliance on surface water for bathing and washing – a common cholera transmission pathway. We do not find that households invest additional resources into drinking water treatment, nor do we find reductions in self-reported cholera incidence. Further, households with a static, non-personalized app containing public health information about cholera exhibit similar patterns of beliefs updating. Taken together, our results suggest that access to risk information can help households make safer water choices, yet improving design and credibility remain important dimensions for increasing application usability.

The ongoing debate concerning the ranking of taxes versus cap and trade for climate policy begins with Weitzman’s (1974) seminal slope-based criterion and concludes that taxes likely dominate quotas. We challenge this conclusion and the intuition behind it. Because technology shocks and pollution stocks are both persistent, a technology shock alters the intercepts of both the marginal damage and abatement cost curves. The ratio of these two intercept shifts is as important as the ratio of slopes in ranking policies. Technology innovations diffuse gradually, strengthening the importance of the ratio of intercept shifts. For plausible parameter combinations, quotas can dominate taxes.

Using quarterly temperature and employment data between 1990 and 2021, this paper uncovers nuanced evidence on the impact of seasonal temperature within US counties: higher winter temperature increases private sector employment growth while higher summer temperature decreases it. The impacts of higher temperature in milder seasons, fall and spring, are statistically insignificant. Moreover, the negative impact of higher summer temperature persists while the positive impact of higher temperature in the winter is more short-lived. The negative effects of a hotter summer are pervasive and persistent in many sectors: most significantly in “Construction” and “Leisure and Hospitality” but also in “Trade, Transport, and Utilities” and “Financial Activities”. In contrast, the positive effects of a warmer winter are less pervasive. The employment effect of a hotter summer has been more severe in recent decades.
