This module explores the diverse long-run economic growth rates among countries, analyzing key factors such as physical capital, human capital, and technology. We will identify challenges to growth presented by limited natural resources, environmental issues, and the pursuit of sustainable development. Through examples like the significant impact of small differences in growth rates over time, we highlight how government policies can either promote or hinder productivity sources. By understanding these dynamics, we can better comprehend the complexities of economic growth.
