iiinova — where your digital self keeps evolving

At least it gives me an opportunity to make nice graphs

Idk but if you pay me $799 than I can work it out

Two things remain on my to-do list: 1/ Assess how well the model performs at predicting the outcome of previous elections ("out-of-sample" performance); and 2/ Incorporate economic variables, such as unemployment, inflation, and interest rates, into the model.

230

Note the model accounts for: - Sampling size ("uncertainty") - House effects for individual pollsters - Public versus internal polls - Trends (by party)

141

The main findings are (see above figures for eye-candy): 1/ Support for the Government (light blue) and Opposition (rose) blocks is neck-and-neck, as are National (dark blue) and Labour (red); and 2/ Support for the smaller parties is sitting at similar levels to the last general election.

⭐ New Zealand polling update⭐ As we wait on new polling data following the recent budget here in New Zealand, I thought I'd crank the handle on my model that aggregates political polling data and infers the "average" levels of support for individual parties.

Put simply, turbo-charging urban development can complement the provision of infrastructure to rural areas, and vice versa. I enjoyed writing the post and hope you enjoy reading it. Ka kite! Thanks again to @greaterauckland.bsky.social for facilitating these conversations.

The post finishes by observing how improving infrastructure in New Zealand's remote / rural communities can also deliver tangible value to urban areas, by providing access to obscenely beautiful natural environments. Like Wharariki Beach.

Infrastructure "cross-subsidies" from urban to rural areas are already happening, of course, and have happened for eons. For me, the focus should be on ensuring New Zealand has a sufficiently large and prosperous urban core to sustain these cross-subsidies into the future.

151

The post discusses how adopting policies to strengthen the urban core, such as upzoning to enable housing, can support remote, rural communities. How? Well, it spreads the fixed costs of providing infrastructure over more people, reducing costs per person. E.g. the road to Rangiwhakaoma.

It'll depend on the context but high land prices supporting higher density development seems intuitive to me. But we might have achieved better outcomes from allowing 4-10 storeys in more places.

Thanks to Matt for his efforts, several people for helpful comments on an earlier draft, my employer Motu for supporting unfunded research, Land Use Policy for publishing what is an unusual paper, and the Vrije Universiteit Amsterdam for paying the open access fee. Onwards and upwards!

Stu Donovan @studonovan.bsky.social · 12/02/2025

Main takeaways: - the evidence suggests upzoning in Auckland led to more supply and lower rents - these findings hold under plausible assumptions and are very robust to changes in those assumptions - all available evidence indicates upzoning had large effects The conclusions sum up where we stand.

And just like in Auckland, the synthetic control method shows rents falling soon after the reforms with the size of the effect growing with time. Honestly, this is beautiful.

Like Auckland, the paper presents data showing a big spike in housing permits especially for apartments and townhouses.

I should say the benefits of bus priority above and beyond their effects on speed, which are already captured.

One of my final fun projects as a consultant in Australia was to contribute to a project that sought to incorporate the benefits of bus priority into a macroscopic ("strategic", or four step) transport model. You can read more about the process here. veitchlister.com/bus-priority...

Does housing affordability and security affects fertility? According to this study the answer is "yes": When people aged 20-25 years are given social housing (via lottery), then they are 32% more likely to have a child and end up having 33% more children in total. papers.ssrn.com/sol3/papers....

And great comments from Dorina Pojani: "... homeowners losing out on capital gains was a "fair price to pay" to ensure more people had a roof over their heads. "If new developments cause housing prices to go down, I — as a planner — am completely fine with that because we want prices to go down ..."

Great decision from Brisbane City Council to allow this apartment building.

Lower home values a fair price for more housing, planner says

"Impacts on the value of adjoining properties are not a matter for consideration under the planning scheme ... The development contributes to Brisbane's housing in that it is diverse in type and form, offering choice to different household types and income levels ..." www.abc.net.au/news/2025-01...

Apartment owners in the Brisbane suburb of St Lucia fear a new development nearby will lower their property prices, but urban planners say housing affordability is more important.

Hmmmm not sure. Keep in mind that realtors revenue is a function of prices and volumes. Upzoning reduces the former (lower prices) but increases the latter (higher volumes).

Stu Donovan @studonovan.bsky.social · 22/12/2024

those standards could also be set nationally, though. A national standard doesn't have to be the same everywhere, e.g. insulation, geotech etc. Rather, it just means that the response to local conditions is nationally consistent.
