The Textbook „Theorien der Wirtschaftsgeographie“ (Theories of Economic Geography) by Ingo Liefner and Ludwig Schätzl is now available in 11. Edition. The book introduces the corpus of theories used in economic geography. Its structure reflects the so-called „Raumwirtschaftlicher Ansatz,“ which is a concept to determine the object and purpose of the economic geography discipline. The new edition additionally discusses some more recent theories and terms such as institutions, evolutionary approaches and Kuznets waves.
