I'm struck by my 17 month old daughter's affinity with and interest in the concept of private property.

There are classes of objects she knows generally have an owner – like a cup of tea or a pair of shoes – and when she sees a new item of this kind it becomes her priority to establish who it belongs to. She enjoys hearing the answer and telling everyone else about it.

@TheLizVariant VHS tapes are cheap. You can buy a movie for much less than the “buy” option on Amazon Prime at a thrift store or rummage sale with VHS and DVD shelves.

It shows clear risk aversion (upward sloping) and monotonicity (prefers higher μ, lower σ - blue region). It has local noise, but globally follows theory. Would you classify this agent as rational? #EconTwitter @joshuarfoster @BenSManning @BasilHalperin @ben_golub @gleech

Do LLMs possess coherent utility functions?
We mapped the preferences of Llama-3.1 over risky portfolios. A positive logit difference (blue) indicates that the model picked that portfolio over the reference (yellow star) in a binary choice scenario. The resulting indifference contour (black) closely tracks a standard Mean-Variance structural model (yellow dashed line).

@jennfrey This week I volunteered to run dodgeball at Field Day, because that worked for me. I could handle it without dropping other important things. At other times, doing the dress up day, especially for a preschooler(!), did not pass the cost benefit test and got entirely skipped.

@AlecStapp Do you have any grid for thinking about job security in this world? If someone talented really wants to do this but is tempted by the stability of government work, what would you tell them?

@RyanLEllis @MrRBourne Dads can stay home, too.

@dramadork884 @jennfrey Life is full of trade offs. Some days we don’t meet everyone’s (anyone’s) expectations. Still glad I have my kid. Some families can easily accommodate dress up days and some cannot.
