Submit your "core" labor economics papers (wages, employment..) to this great workshop I co-organize for the third time - join with, e.g., Cardoso, Machin, Mogstad and Spitz-Oener for some serious Labor Economics in Helsinki in August!

I don't think the argument for the price system rests on full information. I think it rests on Hayek 1945, hence precisely on dispersed local knowledge --i said that before. But let's leave it here. I think we clarified quite a bit, and I hope some of our readers (if there are any!) learned a bit.

So why does this happen? As we discussed in Lesson 5, it's difficult or impossible to reverse engineer LLMs to get precise answers. 

But we can understand the general problem. For us, the statements "Ed Sheeran has a song called The Crow" and "Ed Sheeran doesn't have a song called The Crow" feel like polar opposites. 

But recall that LLMs encode strings of words in high-dimensional spaces. For the LLM, these statements are very close to one another in that high dimensional space. Both involve Ed Sheeran. Both involve a song called The Crow. What fraction of English utterances involve either, let alone both? To the LLM, whether you throw in the word "doesn't" almost is trivial. 

Principle: predictive text machines like LLMs measure the distance between statements very differently from the way people do. Claims that seem diametrically opposed to us may seem almost identical to them. As a result, they can be wildly inconsistent in their responses.

This paper finds that both ice and hot days increase workplace accidents by ~7%.

Results suggest:

1. Little heterogeneity on hot days, on ice days older workers are more affected and accidents are more severe.

2. Main mechanisms are sleep problems on hot days, slipping on ice days.

A horizontal bar chart titled "Foreign aid given per capita in 2023" shows net official development assistance (ODA) divided by population for various countries. The chart depicts the following countries and their corresponding aid amounts in U.S. dollars:

- Norway: $1,160 (the longest bar, highlighted in green)
- Sweden: $515
- Netherlands: $370
- UK: $255
- France: $225
- US: $190
- Japan: $155
- Australia: $122
- Spain: $69
- Israel: $41 

A note indicates that Norway is the only country giving over $1,000 per capita in foreign aid. The data source is from the OECD, dated 2024, and the image has a copyright notice stating "CC BY."

Vuoden 2018 alkoholilain uudistuksen vaikutuksista

Tutkimuksemme 2018 alkoholilain uudistuksesta: aiempaa vahvempien alkoholituotteiden myynti PT-kaupassa jopa viisinkertaistui suhteessa myynteihin Alkossa aiemmin. Silti alkoholin kokonaiskulutus ei noussut.
