with H. Spencer Banzhaf, Martin Smith, Frank Asche: w26398
Extending recent results in the industrial organization literature (Carvajal et al. 2013), we de-rive non-parametric tests of behavior consistent with the tragedy of the commons model. Our approach derives testable implications of such behavior under any arbitrarily concave, differentiable production function of total inputs and when individual extractors of the resource have any arbitrary convex, differentiable cost of supplying inputs. We extend the tests to account for behavioral errors in observed data and derive statistical tests based on “how far off” the marginal costs are from those that are consistent with the model. We also extend the tests to allow for sampling error and/or measurement error. Applying our approach to panel data of Norwegian fishers, we find evidence rejectin...
