In the middle of a cost of living crisis, key economic indicators are more important to track than ever. This week on Taxpayer Talk, host Peter Williams sits down with Dr Christoph Schumacher, Professor of Innovation & Economics and Director of the Knowledge Exchange Hub at Massey University. Dr Schumacher and the Knowledge Exchange Hub have developed a tool that tracks Gross Domestic Product (GDP) in real time to monitor how the economy is performing and forecast future performance. This powerful tool can be used to gain a better understanding of our economy quickly, rather than waiting for Statistics New Zealand to publish the figures two and a half months out of date. Following the success of this tool, the next project to be released will be one that tracks inflation in real time potentially revolutionising the way we respond to inflationary pressures.

Also this week, Peter gives his thoughts on the proposed RNZ-TVNZ mega-merger and asks "what problem are trying to fix?" As a veteran broadcaster, Peter knows a thing or two about media and fears this model may make our public broadcasting less independent and impose higher costs on hardworking taxpayers.
