Charts, charts, charts. I'm starting a collection of my main ones here should you want more: ravebydave.blogspot.com.au/2016/04/emtr-a…

An update on Australia's use of the US Strategic Petroleum Reserve: markthegraph.blogspot.com/2026/03/austra… #auspol #ausbiz #ausecon #OOTT

@e11_anna Indeed.

@DPlunky Expect so. Have thought about it but as a renter not sure how you guarantee access to charging power?

Local petrol station almost out. Covid vibes and feels as if Morrison is still in charge & asleep at the wheel. Victorian. Are we going to be stuck at home again? Shudder…..

1, 5 & 10 year change in disposable income for single income couple, 3 young children. 5 year case looks extra wild because it's showing the loss of the COVID supplement.

Austudy's design (?) gives some earners a choice about how much to earn to get a given disposable income. Eg, to get a disposable income of $50K they can earn either $36.7K or $67.5K. Two different ways of showing this in chart form

@e11_anna Did you pass? 😊

Test

@e11_anna Have been reading.

Not sure why I have returned to talking to myself 😅 No one cares. Read only mode. Bluesky missing what I do like here. Uncomfortable, realistic debate on housing and Auspol.

@ZacGross I only included the most common formula scenarios in my spreadsheet. From memory there are several I didn't include, based on their relative obscurity and my laziness. If you want more details, DM me.

@DPlunky Is there a general formula for child support you use?

Might be better for a child support payer not to find a new partner, especially one that's unemployed and looking for work...

I was tempted to give them a HECS debt to really sweeten the deal 😈

@beckyquick83 Maybe, although in the income ranges I mentioned the earner is no longer on Austudy, so it is equally applicable to a couple with only 1 student partner in those cases.

@DPlunky Could this have the salutary effect of deterring students from working too many hours?

I hadn't taken this one for a run for a couple of years: Almost $7K range with EMTR >100% Appears one needs to earn extra $32,500 just to get disp inc back to where it was when earning $47,500. Magnificent stuff.

@markbouris @DrCameronMurray The different unit of assessment between tax and social security and the problems this causes for EMTRs, particularly in sequentially income tested payments. Too niche? 😄

What’s everyone’s take on the Productivity Summit kicking off tomorrow? What do you actually want to hear more about and what are you already sick of hearing?

Oops. That's the same one, twice. Here's the right one.

and a couple more

The recent post from @ChrisEconomist looking over the last decade reminded me to update the handful of charts I do covering a 10 year period...

@BenPhillips_ANU @MattGLilley @lachlanvass Just zooming in on the min wage split, it's interesting to see the dip around the 50/50 mark is still there after several decades. That's what got me into this sort of stuff back in the 90s.

@BenPhillips_ANU @MattGLilley @lachlanvass

Call to simplify family payments. Makes sense although basing the payment on individual incomes rather than family income will likely cost big dollars and benefit mid/high income couples who need the $s less than single parents who’d be no/worse off.

@Austaxpolicy The first example seems odd. It ignores the tax treatment. The single income household is much worse off in net terms.

#NewPost Introduced by the Howard government in 2000, Family Tax Benefit part A and part B are the largest single government program of family assistance spending. They are long overdue for an overhaul, argue Ana Gamarra, Guyonne Kalb and Miranda Stewart. austaxpolicy.com/how-to-fix-aus…

@MattGLilley @lachlanvass @BenPhillips_ANU

@lachlanvass @BenPhillips_ANU Yep, exactly. The single earner HH pays $8k more in income tax. That said, all of these things are bizarre, arbitrary, and it would be better to tax HH income, or better yet, family-size adjusted HH income.
