This book develops new economic theories of the interplay of distribution and accumulation processes in economies with organised agents. It is shown that unionised economies are threatened with dynamic inefficiencies, but they can be alleviated with the help of cleverly designed wage bargaining systems. The book adopts a unified methodological approach in which game-theoretic arguments are combined with dynamic programming techniques. All models are illustrated with figures and numerical analyses. The book will be of interest to economists and social scientists interested in labour markets, wage bargaining and social corporatism, and theories of growth and investment.
