How do exchange rates affect environmental quality?

Abstract

Exchange rates are integral to explaining the environmental consequences of globalization because they govern the prices of imported inputs and the price competitiveness of exports and, consequently, firms' input use decisions, production levels and emissions. We study how exchange rates, foreign input sourcing and export orientation determine environmental outcomes across countries and industries in both theoretical and empirical contexts. For industries that rely intensively on imported intermediate inputs, a stronger domestic currency leads to higher emission intensities (emissions per unit of output), while the reverse holds for industries that export intensively. Our results thus show that exchange rates have implications for the environment that have heretofore remained unexplored. Quelle est l'incidence des taux de change sur la qualité de l'environnement? Les taux de change font partie intégrante de l'explication des conséquences environnementales de la mondialisation, car ils régissent le prix des intrants importés et la compétitivité des prix des exportations et, par conséquent, les décisions des entreprises en matière d'utilisation des intrants, les niveaux de production et les émissions. Nous étudions comment les taux de change, l'approvisionnement en intrants étrangers et la vocation exportatrice déterminent les résultats environnementaux dans les pays et les industries dans des contextes à la fois théoriques et empiriques. Pour les industries qui dépendent fortement des intrants intermédiaires importés, une monnaie nationale plus forte entraîne des intensités d'émission plus élevées (émissions par unité produite), tandis que l'inverse est vrai pour les industries qui exportent de façon intensive. Nos résultats montrent donc que les taux de change ont des répercussions sur l'environnement qui restent jusqu'à présent inexplorées.
