Inflation, interest rates and the RBA. Warren Hogan economic advisor to Judo Bank provides his prediction of when rates will go up and by how much as well as what are the key questions for a forthcoming review of the RBA. As the Solomon Islands and China deal continues to dominate the election campaign what are the differences in each party's approach to foreign aid and is it economically viable? Stephen Howes, professor of economics at the Crawford School of Public Policy at the ANU discusses. Over ninety billion dollars in revenue could be collected from offshore gas projects if changes to the petroleum resource rent tax (PRRT) are made according to a recent Greens policy. So what is the PRRT, why hasn't it worked and why hasn't the Coalition or the ALP in the past done anything about it? Diane Kraal, senior lecturer at the Monash University's Business School explains.
