My question is to the minister representing the Treasurer, Minister Gallagher. The RBA said yesterday that the board also remains concerned about the continued weakness in productivity growth, and continued weakness will constrain the economy's ability to grow without generating high inflation. The RBA revised down productivity growth in the December quarter to negative 0.5 per cent, significantly below the 0.2 per cent increase that had been forecast by Treasury. Minister, why is productivity continuing to fall?
