Abstract

We model exogenous technology shocks in common-pool industries using a compound Poisson process for total factor productivity. Rapid di�usion of exogenous innovations is typical in the commons, but technology is rarely modeled this way. Technology shocks lower the equilibrium resource stock while causing capital buildup based on transitory pro�ts with myopic expectations. The steady state changes from a stable node to a shifting focus with boom and bust cycles, even if only technology is uncertain. A �sheries application is developed, but the results apply to many settings with discontinuous changes in value and open access with costly exit.
