We propose and test a view of corporate diversification as a strategy that exploits internal information markets, by bringing together information that is scattered across the economy. First, we construct an inter-industry network using input-output data, to proxy for the economy's information...

We document a strong decline in corporate-diversification activity since the late 1970's, and we develop a dynamic model that explains this pattern, both qualitatively and quantitatively. The key feature of the model is that synergies endogenously decline with technological specialization,...
