Productivity-enhancing labour reallocation in Australia
Andrews, Dan; Hansell, David - 2019
International evidence suggests that aggregate productivity growth is driven by the within-industry reallocation of inputs away from less productive firms and towards more productive firms, but little is known about this process in Australia. Accordingly, this paper exploits firm-level data to...

Product market power and its implications for the Australian economy
Hambur, Jonathan - 2021
This paper documents the evolution of firm mark-ups in the Australian economy using a large and representative database derived from administrative tax data. I find that mark-ups have increased by around 5 per cent since the mid-2000s, which is less than previously documented for Australia, and...

Parametric dependence of a morphing wind turbine blade on material elasticity
Puterbaugh, Martin; Beyene, Asfaw - In: Energy 36 (2011) 1, pp. 466-474
A few recent works have suggested a morphing blade for wind turbine energy conversion. The concept is derived from fin … justification of this new concept. This paper establishes a parametric relationship between an asymmetric wind turbine blade and … constituent material modulus to predict the geometric response of the morphing blade for a given material characteristic. The …
