Households face annual costs of roughly $400–$900 from climate change—mainly from disasters, higher insurance, and energy costs—with lower-income families and certain regions hit disproportionately, from @kclausing.bsky.social, Knittel, and @cwolfram.bsky.social www.nber.org/papers/w34525

Exciting news from FAIR 🎉 Professors Erik Ø. Sørensen just received a $23K Peder Sather Grant to study how we can make economics research more transparent, reproducible, and reliable.

Better science helps us all 👏

This is how you can do horizontal bars in #tidyplots 😉

Adapted ggarrow to the new ggplot2 theme features!

```r
library(ggplot2)

ggplot(ggarrow::whirlpool(5), aes(x, y, group = group)) +
ggarrow::geom_arrow() +
theme_minimal(ink = "purple")
```
#ggplot2 #rstats
An x/y plot with arrows spiraling outwards from the center. Everything is a shade of purple or white.

Ever stared at a table of regression coefficients & wondered what you're doing with your life?

Very excited to share this gentle introduction to another way of making sense of statistical models (w @vincentab.bsky.social)
Preprint: doi.org/10.31234/osf...
Website: j-rohrer.github.io/marginal-psy...
Models as Prediction Machines: How to Convert Confusing Coefficients into Clear Quantities Abstract Psychological researchers usually make sense of regression models by interpreting coefficient estimates directly. This works well enough for simple linear models, but is more challenging for more complex models with, for example, categorical variables, interactions, non-linearities, and hierarchical structures. Here, we introduce an alternative approach to making sense of statistical models. The central idea is to abstract away from the mechanics of estimation, and to treat models as “counterfactual prediction machines,” which are subsequently queried to estimate quantities and conduct tests that matter substantively. This workflow is model-agnostic; it can be applied in a consistent fashion to draw causal or descriptive inference from a wide range of models. We illustrate how to implement this workflow with the marginaleffects package, which supports over 100 different classes of models in R and Python, and present two worked examples. These examples show how the workflow can be applied across designs (e.g., observational study, randomized experiment) to answer different research questions (e.g., associations, causal effects, effect heterogeneity) while facing various challenges (e.g., controlling for confounders in a flexible manner, modelling ordinal outcomes, and interpreting non-linear models). Figure illustrating model predictions. On the X-axis the predictor, annual gross income in Euro. On the Y-axis the outcome, predicted life satisfaction. A solid line marks the curve of predictions on which individual data points are marked as model-implied outcomes at incomes of interest. Comparing two such predictions gives us a comparison. We can also fit a tangent to the line of predictions, which illustrates the slope at any given point of the curve. A figure illustrating various ways to include age as a predictor in a model. On the x-axis age (predictor), on the y-axis the outcome (model-implied importance of friends, including confidence intervals). Illustrated are 1. age as a categorical predictor, resultings in the predictions bouncing around a lot with wide confidence intervals 2. age as a linear predictor, which forces a straight line through the data points that has a very tight confidence band and 3. age splines, which lies somewhere in between as it smoothly follows the data but has more uncertainty than the straight line.

Millions of followers ≠ engagement. @theguardian.com has 1.4m followers on Threads with almost no engagement. On Bluesky, links can get 3–4x more clicks than likes.

The real question isn’t “how many followers do you have?” but “what kind of engagement do you get?”

I’ve got a new working paper with @danielavidart.bsky.social, hot off the press. We develop a new method for measuring the risk preferences of agents in the past, and apply it to the U.S. from 1890-1920.

Check it out! Feedback is welcome.

I'm so excited to see this paper coming out in RESTUD.

Fun facts about this paper:
1) My amazing co-author Bruno and I had never met in person until after we completed the first draft.
2) It's my first and only paper that was never rejected by a journal.
3) I can now claim to understand macro.

This looks a must read for those interested in triple differences (DDD) designs.

It shows that the standard way many estimate DDD is wrong.

It shows why and gives you tools that work with covariates and staggered adoption.

Bonus: free R package.
