Productivity in the Mining Industry: Measurement

Yet output growth in mining in recent years has been weak at best, and multifactor productivity (MFP) has declined by 24 per cent between 2000-01 and 2006-07. Long lead times between investment in new capacity in mining and the associated output response can lead to short term movements in mining MFP unrelated to underlying efficiency.
