I am an applied microeconomist working primarily on environmental issues, with a focus on firms and the environment. My recent work shows how changes at the firm in response to environmental policy contribute to a cleaner economy, and how environmental policy affects a firm’s decision to participate in foreign markets.

Abstract: This paper investigates how a common form of environmental regulation—air quality standards—affect exporters. We develop a simple theoretical model to show how the design of these standards causes: (i) some firms to stop exporting, and (ii) a reduction in the export volumes of affected continuing exporters. We exploit quasi-experimental variation resulting from the design of Canadian air quality standards to test these predictions empirically. Our estimates confirm our model's predictions: we find that for the most affected manufacturers, regulation reduced export volumes by 32% and increased the likelihood plants stop exporting by 5 percentage points.

Abstract: For much of the industrialized world, pollution from manufacturing has been falling despite increased output. We examine how air quality standards—a common environmental regulation—have contributed to this "clean-up" of manufacturing. We develop a general equilibrium model to show how air quality standards can lead to a clean-up by causing: (i) reductions in plant emission intensity, (ii) relative changes in plant output, and (iii) plant entry and exit. We provide quasi-experimental evidence from Canada to highlight the magnitude of these responses. Our results suggest that air quality standards explain just under 40% of the clean-up of manufacturing.

McAusland, C.; Najjar, N., 2015, "Carbon Footprint Taxes", Environmental and Resource Economics, May 61(1): 37 - 70.
Abstract: We analyze whether a carbon consumption tax is logistically feasible. We consider a carbon footprint tax (CFT), which would be modeled after a credit-method value added tax. The basis for the tax would be a product’s carbon footprint, which includes all of the emissions released during production of the good and its inputs as well as any greenhouse gases latent in the product. Our analysis suggests that a pure CFT, requiring the calculation of the carbon footprint of every individual product, may be prohibitively costly. However a hybrid CFT seems economically feasible. The hybrid CFT would give firms the option to either calculate the carbon footprint of their outputs—and have their products taxed based on those footprints—or use product-class specific default carbon footprints as the tax basis, thereby saving on calculation costs. Because the CFT would be levied on all goods consumed domestically, the CFT would keep domestic firms on an even footing with those producing in countries without active climate policy, protecting competitiveness and reducing leakage.
