      abstract = {Intellectual Property Regimes (IPRs) have been justified  on the basis that they promote
innovation, but it is not  always clear that they do so. Empirical studies of IPRs in  an
Australian context have been limited. Plant variety  protection is one form of IPR. The passing
of the  Australian Plant Breeder’s Rights Act of 1994 has been  followed by significant
commercialisation of the wheat  breeding industry. The purpose of this paper is to  consider
whether this commercialisation has benefited wheat  productivity through varietal
improvement. We estimate a  linear crop production function, using a random  effects
Hausman Taylor estimator to evaluate differences in  genetic contributions to productivity
between public and  private wheat varieties commercially released in NSW over  the period
1992-2009 using crop varietal data. Results from  the Hausman Taylor estimator show that
private varieties,  on average, have outperformed public varieties over the  period, suggesting
that Plant Breeder’s Rights has promoted  productive innovation in wheat. However, when we
consider  the best performing genetics of the varieties, public  varieties have, in some years,
outperformed privately bred  varieties.},
