This article got featured in the ABC today - but something's fishy about it

, isn't this a levelling-down argument? Rent is too much, so let's equalise by making home ownership pricier? Improving inequality by increasing the cost of living?

The government has asked for bold proposals. Maybe itβs time to consider taxing the family home
When it comes to improving the fairness of the tax system, this is no time to be squeamish.

Finally, we have a published version of the paper describing the ontology for capturing information about recipients of interventions. It's out for peer review but open to comments from all interested parties so do have a look and stress test it!

New Preprint! There has been a lot of work on models coupling behaviour with disease dynamics, typically (and understandably) agnostic about the exact behaviour. Here we consider specifically testing and isolation, providing mathematical and numerical analyses.
