| Abstract: | Using a panel of nine manufacturing industries in 43 economies over the period 1990-2015, we examine how international commodity price movements affect carbon emissions across industries. We find that commodity price movements are associated with larger reductions in emissions intensity in physical-capital-intensive industries, whereas the emissions response does not vary systematically with human capital intensity. The results are economically meaningful and robust. The evidence points to cross-industry reallocation as the dominant adjustment channel, with commodity price movements associated with lower value-added growth in physical-capital-intensive industries, whereas the evidence for within-industry emissions-efficiency improvements is weaker. We further show that industries experiencing larger declines in domestic emissions intensity also exhibit larger increases in emissions embodied in imports, suggesting some relocation of emissions-intensive production across borders. Overall, commodity price movements appear to support domestic decarbonization while raising concerns about carbon outsourcing. |

| Abstract: | Flight-booking websites, such as Google Flights and Skyscanner, increasingly display estimated CO2 emissions for flight itineraries, but little is known about whether this information affects booking decisions. We study how emissions disclosure affects consumers’ flight choices using US domestic flight data from 2018 to 2022 and a discrete-choice model and find that it increases consumers’ sensitivity to flight emissions. In our preferred specification, the absolute value of the emissions elasticity of demand increases from 0.23 in the predisclosure period to 0.28 in the period following the first disclosure. Expressed in willingness-to-pay (WTP) terms, the implied WTP for emissions reductions is $33 per ton higher in the postdisclosure period. Counterfactual simulations suggest that mandating emissions disclosure across all flight-booking platforms would further strengthen consumers’ responsiveness to emissions information.Keywords: Willingness to pay, Carbon emissions disclosure, Discrete-choice model, AviationJEL codes: D12, D83, L93, Q58 |

| Abstract: | What factors drove human migration before modern states, markets, and borders? We develop a framework of ecological sorting in which climate-specific subsistence knowledge depreciates with ecological distance. To test this, we use ancient DNA identity-by-descent segments to construct bilateral migration flows across Western Eurasia over the last 10, 000 years. We document four main findings. First, migration flows decline with differences in growing degree days, precipitation, and soil characteristics between origins and destinations. Second, the dimensions of climate that bind vary across subsistence systems: farmers exhibit strong thermal and soil matching, while pastoralists match most strongly on precipitation-consistent with differential ecological constraints and limiting factors. Third, periods of warming increase farmer expansion while cooling increases pastoral expansion in patterns that recover known archaeological migration episodes. Migration also acts as a margin of climate adaptation: populations exposed to temperature change move to destinations that partly offset the shift. Fourth, genetic flow predicts subsequent convergence in destination vegetation toward migrants' ecological profiles, consistent with migration shaping landscape change and the demic diffusion of subsistence practices. |
