Joint with: Luis Garicano
We present a model of endogenous growth in which agents acquire knowledge as organizations develop and allocate labor more efficiently. Building up organizations and acquiring the relevant pieces of complementary knowledge,
takes time so organizations develop slowly. As the technology is better known and the majority of problems faced in production are well understood, incremental
knowledge is less and less useful: productivity increases at a decreasing rate. But the depth of expertise accumulated facilitates the appearance of new, radical innovations. Eventually incremental growth slows down sufficiently that
agents choose to switch to a new technology, making existing organizations obsolete. We show that better communication technology increases the long term growth rate of the economy as larger organizations can organize labor and
knowledge more efficiently over longer periods. Our model can rationalize the cross-sectional relation between organization and development. It can also help explain the absence of returns to scale in research and the existence, which we document, of large long term technological cycles.
