Inheritance taxation is unpopular, even amongst people who are unlikely to ever have to pay it. Why? In four different studies - experiment! panels! behaviour! - @cvalebeek.bsky.social and I show political trust is a strong predictor for support for the tax. www.tandfonline.com/doi/full/10....

Political trust and inheritance taxation: evidence from four studies
Inheritance (estate) taxation is a potentially powerful instrument for reducing inequality and raising state revenues, yet it attracts opposition well beyond the small minority who will ever pay it...

The projected fiscal gap has fallen dramatically: from 2.6% to 0.1% of GSP. But under unchanged policy, the primary balance remains in deficit in 2065-66 and gross debt rises from 19.4% to 89.9% of GSP.

Stable income inequality ≠ equality of opportunity. Wealth is much more unequally distributed: homeowner households hold around 17× the net wealth of renters. Measured inheritances & gifts also rose from $8bn in 2001-02 to $31bn in 2023-24. 4/5

Treasury also finds substantial potential benefits from more infill development. Interestingly, homeownership is projected to recover from 64.8% to around 69%, but this relies on fairly strong assumptions about house prices, incomes and ownership costs. 3/5

Housing is about household structure and location—not just population growth. Average household size is projected to fall from 2.4 to 2.2. NSW may therefore need ~2 million additional dwellings by 2066, even as population growth slows. 2/5

I had a look at the new 2026-27 NSW Intergenerational Report, which projects demographic, economic and fiscal trends to 2065–66 under “no policy change”. Three things stood out to me on housing, inequality and the state budget. 🧵 1/5

Interesting working paper on wealth mobility in Germany by Markus Grabka, @pmlersch.bsky.social, @smaexie.bsky.social, and @drschnitzlein.bsky.social population-economics.committee.socialpolitik.de/sites/defaul...
Abstract 
This paper provides the fi rst systematic evidence on intergenerational wealth mobility in Germany 
using newly harmonized wealth data from the German Socio-Economic Panel (SOEP) spanning nearly 
three decades (1988–2017). Linking parents and their adult children, we estimate intergenerational 
rank–rank correlations (IRRC) in net wealth to assess the persistence of relative wealth positions 
across generations. We fi nd substantial wealth persistence in Germany, with an IRRC of around 0.25. 
Strikingly, this association remains highly stable across two observation windows (1988–2002 and 
2002–2017), despite pronounced changes in the macroeconomic and institutional environment. 
Mobility curves indicate that the rank–rank relationship is approximately linear and exhibits little 
evidence of strong non-linearities at the top or bottom of the parental wealth distribution. We 
further document limited heterogeneity by off spring gender and birth cohort, and show that 
controlling for parental income and education attenuates the IRRC only modestly, suggesting that 
wealth captures an additional dimension of socioeconomic advantage beyond standard indicators of 
parental background. In an international perspective, Germany exhibits lower intergenerational 
wealth persistence than the United States. Exploratory evidence suggests that cross-country 
diff erences in homeownership may account for a sizable part of this gap, highlighting the potential 
role of housing-related institutions in shaping intergenerational wealth mobility. scatter plot titled “The Great Gatsby Curve in Wealth.”
X-axis: Wealth inequality in 2005 (more inequality to the right).
Y-axis: Intergenerational wealth correlation (higher values mean less mobility).
Countries country United States, Sweden, Italy, Taiwan, Norway, Germany, South Korea, Denmark, France, Australia, Japan
inear trend line (slope ≈ 0.46) shows a positive relationship: countries with greater wealth inequality tend to have higher intergenerational wealth correlation, meaning lower wealth mobility.
The United States and Sweden toward the upper-right; Denmark and France are lower-left; Germany in the right-middle.

(A) Cost-sharing cushions the impact of carbon pricing for tenants, especially in inefficient homes—but cannot offset general energy price spikes (B) Targeted retrofits significantly reduce heating costs (by up to 58%) and can virtually eliminate energy poverty among the most vulnerable.

Maximilian Longmuir @smaexie.bsky.social · 11/06/2025
To address this, we compare the effects of two policies under regular energy prices and energy price hikes such as observed in the recent energy price crisis: (1) Carbon pricing with tenant-landlord cost sharing, where landlords bear a greater share of the CO₂ cost if a building is inefficient.

Maximilian Longmuir @smaexie.bsky.social · 11/06/2025
