Spain and Portugal are the fastest growing economies in Europe because they have cheap renewable energy. How long before they expand capacity to export electricity to the rest of Europe?

I've been waiting for this.

Japan has run debt >200% of GDP for decades, with no default and persistent fiscal capacity.

MMT predicted this outcome: a currency issuer with floating FX and domestic-currency debt faces real resource and inflation constraints, not solvency constraints. Japan behaves exactly that way.

(3/3) A weaker yen does not create yen insolvency. Japan’s liabilities are yen-denominated. FX movements affect relative prices and import costs, not the state’s ability to pay yen obligations.

But look at me, showing you the egg on your face.

(2/3) Rising JGB yields reflect BOJ policy choices and rate-path expectations. The central bank sets the price of reserves and can cap yields if it chooses. Higher yields does not equate to markets denying Japan funding.

(1/3) MMT does not claim β€œlow inflation -> low bond yields.” It claims a currency-issuing state cannot become insolvent in its own currency. You are conflating fiscal capacity with bond market pricing. Those are different categories.

Tall, middle-aged man seeking collaborator for light applied econometrics.

Interests include revenue stability, distributional outcomes, sectoral behaviour (vacancy, market power), and policy falsification. No drama - R or Python. Must be comfortable with regressions and bad-ass ideas. No romance.

I genuinely wonder if Trump realises that a US president has no legal power to postpone or cancel federal elections, even under martial law or in a civil war.

Many recurring economic failures look less like incentive problems and more like system design failures.

I tried analysing political economy the way a software engineer analyses architecture.

Why Ireland’s Vacancy Policies Are Designed to Fail Vacancy is Rewarded, Not Prevented

Ireland doesn’t have empty buildings because it lacks laws. It has them because leaving property unused is cheap, safe, and rewarded by system design.

This short article is about why vacancy taxes and enforcement fail, and what would actually fix it.

The graphic seems to have omitted the 'don't know' results, but it is a sign of the times that 46% can't immediately tell right from wrong.

The Cost of a Missed Climate Opportunity How delaying investment turned climate obligations into a bill

Ireland is facing climate fines, but that is not really the story. This is about a political choice to delay investment in transport and energy, and why that delay is now being priced.

'Door firmly closed' on increased sick days for workers, despite previous commitment Enterprise minister Peter Burke said the Government had also changed the trajectory to a living wage from 2026 to 2029

Here’s the article that prompted my response: the Government’s decision to close the door on expanded sick leave.

My post digs into what it means when authority is presented as necessity.

When Authority Pretends to Be Necessity Closing the Space for Argument on Sick Leave

Closing the door on sick leave doesn’t remove the cost of illness. It decides who carries it: workers, the public, and a private insurance system that profits from exclusion.

That’s not inevitability. It’s a choice.

Bad old Catholic Ireland is right.

The current housing crisis has everything to do with the real estate sector controlling the government and nothing to do with imaginary friends.

This is a necessary correction. Framing technology as a national policy lever ignores that both tech trajectories and profits are organised through global value chains. Once accumulation depends on cross border labour arbitrage, domestic β€œpro worker” tech policy is structurally constrained.

Same Struggle, Different Language (Part 2) How Progressive Movements Undermine Their Own Demands

Progressive movements are morally clear and highly organised, yet their demands are repeatedly diluted or delayed.

It's not a question of values or effort, but of economic assumptions that enter strategy before demands are set, weakening movements from the inside.

The Inheritance the Far Right Cannot Claim Irishness, memory, and the poverty of exclusion

Health shocks are now credibly associated with the release of premium vegetable assets, creating a moral hazard and accelerating delinquency across the nutrition schedule.

Vegetables in this household now function less as food and more as contested infrastructure, vulnerable to opportunistic extraction during governance failure.

The threatened deployment of ginger soup confirms a deeper incentive distortion...

No increase in total soup supply was observed, indicating the original constraint was normative rather than material. This reallocation established a precedent, triggering secondary allocation pressures including early access requests for mandarins earmarked for deferred healthy consumption.

I woke up with flu like symptoms and impaired cognition, constituting a negative health shock. In response, a minestrone scarcity constraint imposed the previous evening by the household provisioning authority was relaxed and the asset reclassified from dinner input to medical intervention.

4:36am - this is what's kept me awake so far:

Which fiscal structures are inherently unstable?

When does inequality become system breaking rather than redistributable?

Which forms of economic power cannot be safely permitted?

How much extraction can a system tolerate before legitimacy collapses?

This version (2.0) is substantially revised for clarity, precision, and coherence. Comments and critical engagement are welcome.
