The book "Managerial Economics and Value Chain Management" offers a comprehensive introduction to the fundamental approaches of production, finance, and marketing theory. It addresses the two central areas of economics, namely supply and demand, and also delves into project analyses as well as approaches to value chain management. This work is aimed at students at the bachelor's, master's, and doctoral levels and is particularly valuable for those looking to tackle decision-making problems in various types of organizations. Unlike business administration, which focuses solely on profit-oriented companies, managerial economics also provides solutions for non-profit organizations such as schools and hospitals. The broader perspective of managerial economics makes it an essential guide for anyone looking to successfully navigate today's complex economic landscape.
