My theory is that this very important glitch in public economic reasoning stems from the length of time it takes to build homes (and that homes are built when prices are rising).

Ireland has ~1.5 million homes suitable for families. Ireland is very unlikely to ever have more than 0.8m families (with kids under 18). Unbelievable that anyone paying attention to the housing crisis could have missed that the crisis is/will be for 1-2 person households. www.rte.ie/brainstorm/2...

Ireland has overtaken another EU member state, in population, for the first time since joining the EEC back in 1972. At current trends, Ireland will overtake Finland in 2028. (And Scotland maybe in 2027, just about.)

Important evidence on why housing is not like other markets - not because demand and supply don't work but because voters don't believe they do (despite the evidence). Likely key here is the long lag required to get new housing supply v other goods - so extra supply is associated with higher prices.

The latest JEP has an extraordinary set of papers on the economics of housing. My favorite? The one showing that most people incorrectly believe that increasing housing supply won't lower housing costs. Subsidizing home-buying is popular even though it raises costs. 🤦 www.aeaweb.org/issues/814

Given the CSO's pioneering work to develop true measures of national well-being in a globalized world economy, Ireland can feel a little bit cheated at being left out! For those curious, GNI* in 2024 was 57% of GDP. Following that thru, it would place Ireland ~10th, level with Germany.

Births weren't officially registered in Ireland until 1864 and then the census returns were burnt in the Four Courts, making it really hard for people in the 1920s/30s to prove their ages to get a pension. The acceptable alternative documentation included dated birthday cards

Why do women engage in sex work, especially given the health risks associated with the market? This paper shows that during a historical recession, the number of sex work establishments rose, suggesting that economic hardship may drive women into the market.

What determines electoral success in Ireland? Evidence from the last 30 years says being a woman reduces re-election chances by ten percentage points. Don't be in the out-going government (unless you're a Senior Minister). And Being Junior Minister, it turns out, does nothing.
esr.ie
Determinants of Incumbent Electoral Success: Evidence from 30 Years of Irish Elections | The Economic and Social Review
We examine the determinants of incumbent electoral success among members of Ireland’s lower house of parliament, Dáil Éireann, over a time-period covering seven General Elections (1992 to 2020). We utilise multiple sources to create a dataset linking incumbent politicians’ electoral outcomes to personal characteristics, constituency and election-specific characteristics, as well as a range of constituency-level socioeconomic variables. Our analysis reveals a number of important factors in determining the re-election success of politicians. Notably, being a woman reduces an incumbent’s chances of re-election by 10 percentage points, even after controlling for a wide range of other potentially important factors. Holding a senior ministerial position is found to significantly boost an incumbent’s re-election prospects, while being a junior minister has no impact. However, absent a senior ministerial position, being a member of a ruling government party or coalition is associated with significantly lower re-election success. We construct a measure of competitiveness and find that an incumbent in a more competitive constituency is less likely to be elected, while past performance, as measured by the order in which an incumbent is elected in the previous contest, is found to be an important predictor of current success.

And that's ok because the vast majority of additional housing required in all high-income countries is housing for 1-2 person households.

Interesting paper on effect of interviewer gender on gender gap in reported housework. "women tend to report significantly more hours of housework when interviewed by a woman rather than by a man" link.springer.com/article/10.1...
The regression table examines factors influencing daily housework hours for women and men, highlighting key findings:

- **Female Interviewer:** Women spend more time on housework with a female interviewer, increasing the gender gap.
- **Paid Work Time:** More paid work reduces housework time for both genders, more so for men.
- **Income:** Higher income correlates with less housework for both.
- **Marital Status:** Married women do more housework; married men do less.
- **Children:** Having children increases housework for both, with significant effects across all child age groups.
- **Interview Length:** Longer interviews slightly increase men's housework time.

The model explains 16.7% of the variance for women and 9.09% for men, based on 18,965 individuals and 110,544 observations. (Summarized by mistral)

Just as important as the general increase in tariffs is the complete abandonment of the principle of non-discrimination, which the US had traditionally championed. This will further increase international tensions at a time when the US is ripping up the post-1945 security architecture.

For Europeans that absolutely need to travel to the US at the moment, I suggest looking into flying through Dublin airport in Ireland and doing the US-Pre-Clearance there. That way if you get rejected by border control, you are in Europe and can return home a lot easier.
