East German espionage raised GDP by 7.4% in late 1980s, study finds

In the late 1980s, East Germany's extensive Cold War espionage initiatives significantly boosted its economic output, according to a study by the Rockwool Foundation Berlin. The research, focusing on 1988—the year preceding the Berlin Wall's fall—revealed that industrial value added rose by 22.3%, equivalent to 20.2 billion East German marks or €4.1 billion in current prices.

Lead co-author Adrian Lerche emphasized the study's relevance today, as governments worldwide tighten export controls, scrutinize foreign investment, and protect strategic technologies. The intelligence service, Stasi, played a pivotal role in facilitating this economic growth by helping East German companies obtain valuable scientific and technical information from Western businesses and institutions.

Companies benefiting from this intelligence reported faster productivity growth, increased investments, and a greater focus on core products. According to co-author Albrecht Glitz, the Stasi's espionage efforts strengthened East Germany's standing within the socialist bloc but did not significantly enhance its competitiveness in Western markets.

The researchers found that the gains resulting from espionage cascaded through supplier and customer networks, amplifying broader economic effects. Each piece of valuable intelligence generated an estimated annual return of around €330,000 in 2020 prices, underscoring the substantial impact of this covert economic strategy.
