This course defines the context of a regional economy, taking a systems approach to sustainable development planning. Students will be introduced to the techniques of input-output analysis and will learn how to use social accounting models to evaluate social and environmental impacts. We will use international datasets and will also learn IMPLAN, a software and database designed to quantify the impact of exogenous forces on U.S. regions. Examples of exogenous forces include out-migration of population, natural disasters, financial flows, or the introduction of new activities. The course methods enable practicing professionals to integrate environmental and social dimensions of planning into the framework of economic impact analysis.
