This module covers the different dimensions of a sustainable economy, i.e. material well-being, social justice and inclusion, and ecological sustainability, from a macroeconomic perfective. Pursuing these goals may involve trade-offs which generate difficult problems for economic policy. We analyze how current economic systems deal with these trade-offs and reflect on alternative models to organize the economy. In particular, we discuss the concepts of limits to growth, green growth, post-growth and degrowth and their macroeconomic and societal consequences. An important topic of the module is how to deal with the uncertain future and how to acquire future literacy, which is closely linked to the question of sustainability. The module covers methods of futures research like scenario thinking, which are widely used in government agencies and large companies. Finally, we discuss how the transition toward a more sustainable economy can be achieved.
