α: calibrated so average coauthorship-adjusted count equals average raw count
This paper studies the model equation YTÂ =Â [lambda]YTÂ -Â 1Â +Â [alpha]0XTÂ +Â [alpha]1XTÂ -Â 1 and its error-correction equivalent as a temporal aggregate of an underlying true equation in continuous time. Given a stylized fact about [alpha]0Â /Â [alpha]1 we find that this underlying equation is not a Koyck partial adjustment model, but again an error-correction model. An illustration is given.
