α: calibrated so average coauthorship-adjusted count equals average raw count
This paper considers a matching model with both idiosyncratic productivity shocks that hit jobs at random and heterogeneity of workers according to ex ante unobservable abilities. We argue that firms' decisions about reservation productivity can help explain the shape of wage distributions. This is shown from numerical experiments, calibrated to French data, by considering alternative ranges of productivity shocks.
