(p. 183) We have argued that the remarkable transformation of the German economy from the "sick man of Europe" to a lean and highly competitive economy within little more than a decade is rooted in the inherent flexibility of the German system of industrial relations. This system allowed German industry to react appropriately and flexibly over time to the demands of German unification, and the global challenges of a new world economy.
