● Job market paper abstract: Unilateral environmental policy on a tradable commodity raises the classic concern that emissions are displaced rather than eliminated. From 2030, EU Regulation 2024/1787 will exclude crude oil imports above a maximum methane-intensity threshold, a binary, partial-coverage standard imposed on a globally fungible commodity. Using an asset-level model of global oil trade calibrated to over 14,000 deposits, with endogenous abatement and route-specific transport, I find that the standard cleans the EU import basket but has little effect on the atmosphere, because the methane it could remove leaks back almost entirely, at a rate near 0.98. A Shapley decomposition splits this leakage into two channels of similar size: crude rerouted to unregulated buyers, and high-methane crude refined abroad and returned to the EU as product. The abatement the policy could induce is cheap and welfare-improving on its own, but the reshuffling it sets off turns the net effect negative. The import standard is equivalent to a methane price of barely a dollar a tonne. At that same level of abatement, an explicit content price raises EU welfare where the standard lowers it. The near-complete leakage is robust to oil-market power: it persists when the market equilibrium is re-solved with a strategic cartel of Gulf OPEC producers facing a competitive fringe.

● Job market paper abstract: Cities are places where people commute to work and where goods are traded across space. While a large literature examines how lower commuting costs reshape cities, much less is known about within-city trade costs as a distinct force. This paper studies both channels using the construction of the Petite Ceinture railroad in nineteenth-century Paris, the world's first circular transit system, designed for both freight and passengers. Using newly digitized data on firms, population, rents, and transport networks spanning 1801 to 1906, I provide causal evidence that improved access to the railroad reshaped the spatial distribution of economic activities during this period. To quantify general equilibrium effects, I develop and calibrate a quantitative urban model in which within-city freight costs generate spatial variation in tradable goods prices, creating consumption-driven forces at the residence absent from canonical models. Counterfactuals show that removing the railroad would substantially reduce total population, consumption of tradables, and spatial specialization. Ignoring within-city freight costs leads to a 17.1% underestimation of the effects of transport infrastructure on urban structure and welfare.

● Job market paper abstract: Imperfect pass-through of marginal costs into prices reduces the potential welfare gains from input trade liberalization. This paper analyzes an understudied, countervailing effect: as more firms are induced to import (extensive margin), each individual firm is forced to pass through more of its cost reductions in order to retain their market position. I introduce a partial equilibrium model of monopolistic competition under non-CES demand, in which firms choose to either import an intermediate or to source it domestically. The model reveals the theoretical link between the extensive margin and pass-through, and yields a simple way to estimate the relevant parameters in the data. I then quantify the extensive margin for French firms, using detailed product-level price data on both the output and input side. Results show that the extensive margin is sizable, a 10% increase in the marginal cost savings potential from sourcing from abroad increases the share of firms importing by 4.1%. A quantitative exercise using a sufficient statistics approach and parametrizing a Kimball demand system suggests that the extensive margin can explain around 11.7% of the decrease in the aggregate price index following a 10% reduction in foreign prices.
