LABOUR SHARE AND PRODUCTIVITY DYNAMICS

We pose technology shocks where the innovation is biased towards more recently installed plants. On one extreme. the shock is like a neutral technological shock, while on the other end it resembles investment-specific technological shocks. We embed these shocks in a model with putty-clay technology and estimate it requiring that the model replicates the volatility properties of the Solow residual and the overshooting property of the labour share of output. Our estimates show that putty-clay nature of technology, a time bias towards new plants and competitive wage setting replicate well the overshooting property.
