I've traded 22 of @PolicyEngineUK's play-money Budget markets this week. On the reporting, I now put a bank tax rise at 75%, a main CGT rate rise at 20% and a lower mansion tax threshold at 15%.
We've also opened seven new ones. Trade against me: manifold.markets/topic/uk-au…

We're at the International Microsimulation Association World Congress in Brussels, 1–3 July. Three talks:
• Maria Juaristi — local microdata calibration with L0 regularisation
• @vahiidahmadi — firm microsimulation + VAT
• @MaxGhenis — hands-on PolicyEngine tutorial

@MaxGhenis and @ThePolicyEngine team have integrated frontier agentic AI into the most expansive open source microsimulation model of US fiscal policy. AI allows easier use and access as well as automates much of the model creation and maintenance.

Can the government solve the student loan crisis in England and Wales? 💷
And does the system work better in Scotland? 🏴
Watch our analysis featuring new modelling from @PolicyEngineUK and let us know what you think should be done👇

1/3 Excited to share this! For the past 6 months I've been working with the powerhouse No 10 Data Science team @10DowningStreet to push the speed and accuracy boundaries of tax-benefit policy analysis with @ThePolicyEngine 's open source technology.
PolicyEngine is now powering rapid policy analysis at 10 Downing Street.
Our co-founder and CTO @nikhil_woodruff spent 6 months with the 10DS data science team as an Innovation Fellow, adapting our open-source microsimulation model for government use.

We tested whether Claude Code's multi-agent system could automate policy research workflows.
Three specialized agents handled data fetching, Python scripting, and report generation. Now we're applying these insights to develop a Claude Code plugin.

The @OECD's new Global Trends in Government Innovation report highlights how governments are translating regulations and policies into executable code to make public services more consistent, transparent and efficient. This is exactly why we're building PolicyEngine!

Policy wonks- PolicyEngine has recently added capital gains behavioural responses to our freely-available microsimulation model (adding to labour supply responses already).

Anyone on here that wants to be able to quickly and easily answer questions like:
* How much would [tax/ben reform] cost?
* Who would [tax/ben reform] affect?
* How does that change with [X behavioural/economic assumption]?
Come along to PolicyEngine's session on Monday at 2pm!

Super interesting from @PolicyEngineUK - a great group of people doing really good work.
PolicyEngine analysed potential Autumn Budget reforms to Income Tax, National Insurance, Capital Gains Tax and VAT. Here's what we found:
• Raises £23 billion in 2025
• Lowers income inequality by 0.6%
• 47% of revenue comes from top decile

Nice to see this report by @Schalkenbach on land value taxes cite @PolicyEngineUK research on a land value dividend!
For part three of our homelessness series we touch on local housing costs, solutions via a land value tax, and the merits of redistributing land values through a universal basic income.
