This course provides an applied and analytical overview of modern sustainability economics, emphasizing the use of econometric methods to evaluate environmental policies and quantify the value of environmental goods. Students will explore the economics of market failures and externalities, and learn how to assess the effectiveness of policy instruments such as pollution taxes, cap-and-trade systems, and regulatory standards. A core component of the course is the application of microeconometric techniques—such as revealed and stated preference models, discrete choice models, and property value regressions—to estimate willingness to pay, conduct cost-benefit analysis, and measure the impacts of environmental interventions. Through real-world data applications and case studies, students will gain the skills to critically analyze environmental outcomes and inform policy using empirical evidence.
