Exporting and Pollution Abatement Expenditure: Evidence from Firm-Level Data
The relevance of analyzing whether exporting firms engage in greater pollution abatement cannot be overemphasized. For instance, the question relates to the possibility of export promotion policies being environmentally beneficial. In fact, the issue is especially relevant for developing countries typically characterized by ineffective environmental regulation. However, despite the significance of the topic, the extant literature examining the environmental consequences of firm-level trade is skewed toward developed countries. Moreover, the existing contributions rarely attend to concerns ...

Pollution Taxes and Clean Subsidies in an Open Economy
In open economies, the effectiveness of carbon taxes is diminished by “pollution leakage,” where some polluting activity shifts abroad because of the tax. This paper shows that the same conditions that lead to pollution leakage enhance the efficacy of clean subsidies. As a result, the optimal policy in an open economy combines a pollution tax and a clean subsidy, the balance of which depends on the leakage rate. Furthermore, efficient policy sets the sum of the tax and subsidy rates, a measure of policy ambition, equal to the marginal damages from pollution, and does not depend on the ...

Processing Power: The Effect of Data Centers on Wholesale Electricity Markets
Data centers are reversing two decades of flat U.S. electricity demand. We estimate their effect on wholesale electricity markets using an hourly, unit-level dispatch model in which 23 U.S. regional markets trade over capacity-constrained interfaces. Data centers raised wholesale prices by 6.9 percent nationally by 2025 and by 15.0 percent in northern Virginia; under our preferred scenario, the national effect reaches 12.3 percent by 2028. Trade spreads these effects to regions hosting few data centers. Roughly half the increase in generator payments is a transfer to inframarginal generators. ...

Processing Power: The Effect of Data Centers on Wholesale Electricity Markets
Artificial-intelligence-driven data centers are reversing two decades of flat U.S. electricity demand and have generated questions about how this growth will impact electricity prices. We quantify this effect using an hourly, unit-level least-cost dispatch model covering wholesale electricity markets in the continental United States. We find that existing data centers have already increased wholesale prices by 3 to 5% on average nationwide, with substantially larger effects in regions hosting major data center corridors. Extending the model through 2028, we show that if proposed construction ...

If You Build It, They May Not Come: Willingness to Participate in Managed EV Charging
Despite the importance of program participation for policy, treatment effects are often measured on self-selected samples. We study electric vehicle (EV) managed charging, intended to reduce electric grid strain by optimally allocating charging across EVs. Prior work finds large impacts of managed charging among households who volunteer for an RCT. In contrast, we test managed charging with an experiment including all EVs within a California utility. Enrollment is low even with high incentives, and we can reject even modest intent-to-treat effects on electricity consumption. Managed charging ...

The Incidence of Fuel-Price Shocks and Tax Holidays: Evidence from the 2026 Oil Shock
We measure the distributional incidence of U.S. motor-fuel tax holidays using transaction records from ∼13,200 gasoline stations linked to neighborhood income. The 2026 Iran War raised gasoline expenditure shares 2.9 times more in the lowest- than highest-income census tracts. Pre-shock exposure accounts for 89% of the gap while the residual heterogeneity widens rather than offsets it. State-level tax holiday lowered retail prices but offset the same fraction (28%) of the per-gallon burden across quintiles. A counterfactual federal holiday preserves this incidence. Per-gallon relief is ...

Refining the Workhorse Oil Market Model
The Kilian and Murphy (2014) structural vector autoregressive model has become the workhorse model for the analysis of oil markets. I explore various refinements and extensions of this model, including the effects of (1) correcting an error in the measure of global real economic activity, (2) explicitly incorporating narrative sign restrictions into the estimation, (3) relaxing the upper bound on the impact price elasticity of oil supply, (4) evaluating the implied posterior distribution of the structural models, and (5) extending the sample. I demonstrate that the substantive conclusions of ...

Facts and Fiction in Oil Market Modeling
A series of recent articles has called into question the validity of VAR models of the global market for crude oil. These studies seek to replace existing oil market models by structural VAR models of their own based on different data, different identifying assumptions, and a different econometric approach. Their main aim has been to revise the consensus in the literature that oil demand shocks are a more important determinant of oil price fluctuations than oil supply shocks. Substantial progress has been made in recent years in sorting out the pros and cons of the underlying econometric ...

Facts and Fiction in Oil Market Modeling
Baumeister and Hamilton (2019a) assert that every critique of their work on oil markets by Kilian and Zhou (2019a) is without merit. In addition, they make the case that key aspects of the economic and econometric analysis in the widely used oil market model of Kilian and Murphy (2014) and its precursors are incorrect. Their critiques are also directed at other researchers who have worked in this area and, more generally, extend to research using structural VAR models outside of energy economics. The purpose of this paper is to help the reader understand what the real issues are in this ...

The Econometrics of Oil Market VAR Models
Oil market VAR models have become the standard tool for understanding the evolution of the real price of oil and its impact in the macro economy. As this literature has expanded at a rapid pace, it has become increasingly difficult for mainstream economists to understand the differences between alternative oil market models, let alone the basis for the sometimes divergent conclusions reached in the literature. The purpose of this survey is to provide a guide to this literature. Our focus is on the econometric foundations of the analysis of oil market models with special attention to the ...
