This paper extends the literature on the potential negative employment effects of environmental policy by bringing to the fore a key factor that directly regulates its magnitude: the elasticity of substitution between labor and energy. Using firm-level data from the French manufacturing sector and addressing endogeneity concerns, we provide empirical estimates that point to strong complementarity between labor and energy. We then investigate the empirical relevance of the elasticity of substitution in studying firms’ response to changing energy prices. Our findings suggest that the negative employment effects of rising energy prices are largely driven by firms with limited substitution capacity.

Effective climate change mitigation requires green innovation, but not all projects have equal social value. We examine the role of innovation heterogeneity in a model where the policy maker cannot observe innovation quality and directly subsidize the socially most valuable green innovations. We find that carbon pricing works as an innovation screening device; this creates a premium on the optimal carbon price, raising it above the Pigouvian level. We identify conditions for perfect screening and generalize results to screening policies under alternative intellectual property regimes and complementary policies. A calibration reveals that screening can justify a carbon price that is up to three times the Pigouvian price.

This paper investigates the impact of the timing of adaptation on the stability of international environmental agreements (IEAs) for different levels of cooperation. This issue is addressed by solving a three-stage coalition formation game in a Nash-Cournot setting. In the first stage, countries decide non-cooperatively on their participation in an IEA. Then, depending on the timing, countries decide on adaptation and emissions in the second and third stage. The game is solved for three levels of cooperation. Countries can either cooperate on emissions (emission agreement), on adaptation (adaptation agreement), or both actions (complete agreement). When emissions are chosen first, this extension to an emission–adaptation game is a generalization of the pure emission game. However, when adaptation is chosen first, the grand coalition is stable, provided that countries sign a complete agreement. With partial cooperation, stable coalitions are small. The results establish a connection between the strategic role of adaptation, the levels of adaptation of non-signatories and signatories for the different types of agreements and the participation in an IEA. Moreover, the results indicate that the grand coalition is stable even when it significantly enhances net benefits.

We develop a simple political-economic model of a climate trap. We apply our model to gasoline taxes, which vary dramatically across countries. Externalities cannot fully account for this. Our model shows that group interests, resulting from the composition of a country’s car fleet, can explain differences in gasoline taxes even among countries with identical fundamentals. Endogenous car ownership can yield multiple equilibria. This can lead to a political climate trap, where a low gasoline tax reflects the views of a majority, but another majority would benefit from transitioning to a high-tax equilibrium with fewer emissions.

This paper explores the spatial spillover effects of water scarcity on local economic activity and examines the role of irrigation in modulating these effects. Utilizing a newly assembled global geospatial data set that combines information on seasonal water availability and economic activity measured by nighttime luminosity, I conduct a spatial econometric analysis at the granular level of $0.25°$ $\times$ $0.25°$ grid cells worldwide. My results reveal that agricultural water scarcity in rainfed grid cells has negative spatial spillover effects on economic activity, extending up to 300 kilometers away. However, the presence of irrigation infrastructure effectively mitigates both the direct negative impacts and the negative spatial spillover effects of agricultural water scarcity on economic activity. These results suggest that the benefits of certain climate adaptation measures may not be confined locally, but are observable at a larger scale. This paper emphasizes the importance of considering spatial dynamics and irrigation in understanding the effects of water scarcity on economic activity, providing valuable insights for water resource management policies targeted at promoting climate-resilient development.

This paper examines the impact of transboundary vegetation fire smoke on the real-time sentiment of Twitter users in Southeast Asia, including countries such as Brunei, Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. We leverage the exogenous variation in wind directions for identification. We find that an increase in upwind fires by one standard deviation reduces the sentiment score by 0.5 percent of a standard deviation (after netting out the impact of unobserved local socioeconomic factors). During peak fire seasons, our estimate translates into sentiment damages comparable to the average Sunday-to-Monday sentiment drop. The adverse sentiment impact exhibits significant variation across countries and intensifies with factors such as the number of upwind fires, income levels, proximity to fires, and limited adaptability on weekdays. We show that cross-boundary air pollution is the primary channel, with smoke from neighboring countries exerting a greater impact on sentiment than domestically produced smoke. These findings underscore the psychosocial costs and geopolitical tensions associated with cross-border air pollution spillovers.

Rivalry in consumption generates variation in the choice sets decision-makers face. Neglecting such variation generates biased demand estimates. Whereas previous research used information from periodic inventory systems to correct this bias, this study instead uses novel data from a real-time inventory system that records all public charging sessions by electric vehicles in a residential area of Amsterdam.

For each transaction I can reconstruct a user’s exact set of available alternatives at the time of arrival which allows me to impose deterministic choice set constraints. I show that this significantly improves demand forecasts for local charging facilities, with estimated differences between observed and latent demand reaching up to 40 percentage points at some locations. For the current demand and infrastructure, consumption rivalry however remains a local phenomenon limited to peak hours. A policy analysis suggests that it is not cost effective to install more capacity just to mitigate consumption rivalry. Instead, it may be better to implement policies aimed at increasing the utilization of existing capacity.

As the amount of solar and wind generation capacity installed in a region grows, there will increasingly be periods during which a portion of the potential renewable generation will need to be curtailed to maintain the stability of the electric grid. Across markets worldwide, average curtailment rates for wind and solar are generally quite low, often around 3%. However, these low average curtailment rates may overstate how much renewable supply increases as a result of further increases in renewable capacity. Using historical hourly generation and curtailment data from California’s electricity market, we estimate that only 91% of the output supplied by new solar capacity goes towards increasing the state’s renewable supply — with the remaining 9% being discarded in the form of increased curtailments.

We study the effect of resource discoveries on dictator failure. We extend existing conflict literature by developing a dynamic stochastic model where timing of attack and probability of success are endogenous. Incumbent and opposition invest in military arsenals which determine success probability, while opposition also chooses when to stage a coup. A resource discovery delays the attack and reduces the probability of overthrow. We test these hypotheses using duration models and timing of giant oil and gas discoveries, finding that large discoveries more than double remaining time until failure and reduce hazard faced by an autocrat by 30%–50%.

Contests are widely used as mechanisms to incentivize efforts in various contexts, from research innovation to athletic and employee performance. This paper builds an analytical model and provides empirical evidence to assess the effectiveness of a large-scale, real-world residential energy conservation contest in Vietnam. The model suggests that contests offering multiple prizes and requiring a minimum amount of effort can effectively promote conservation. It also identifies factors that influence the conservation effort, such as the cost of effort, size of prizes, and types of contestants. To empirically estimate the effect of the energy conservation contest, this paper uses a unique confidential dataset of monthly residential electricity usage with over 45 million observations. The results indicate that the contest significantly reduced electricity consumption among contestants, and the effect of the contest could persist for months after its conclusion, leading to an average abatement cost of $27 per ton of CO2 emissions.
