The book "Roadblocks to the Socialist Modernization Path and Transition. Evidence from East Germany and Poland" was published open access by Palgrave Macmillan. It is a result of the collaborative project Mod-Block-DDR (https://www.uni-bremen.de/en/obstacles-to-modernization-in-the-economy-and-science-of-the-gdr-mod-block-ddr).

This book examines how different economic systems impacted the development of East Germany and Poland. Through comparing these countries while they were centrally planned socialist economies with the periods when they transitioned to capitalism, the inability of socialist economies to modernize effectively and produce sustained economic growth is highlighted. Particular attention is given the role of technological progress and economic growth, institutions, the creation and transfer of knowledge, and post-socialist transformation.
