Donald Trump thinks heโ€™s winning on trade, but America will lose The harm from tariffs will be lasting and deep

Donald Trumpโ€™s trade policy will be hard to dislodge. Its beneficiaries will be well-organised; its victims may not even realise why they are poorer than they could have been

This baseline context has to be defined by an ominous expert. Similarly, all results of the analysis will be taken into account by the expert to identify further actions.

Causal inference is challenging.

Ten indicators of whatโ€™s going on with Americaโ€™s economy Trumponomics has begun to hit Americaโ€™s growth

Donald Trumpโ€™s agenda has been consumed by his chaotic tariffs, a war on the civil service and attacks on the Fed. The dangers of his approach are starting to percolate into the economic data, as these charts illustrate

Sorry guys, I know you don't like it, but every time you talk to a statistician, you realize how useless traditional stats is at conveying any idea about causal inference.

Ok so this Pinheiro and Bates book - physical copy on my shelf having survived multiple international moves and downsizings - has been my bible on mixed effects models. But it's 25 years old, is there a modern (#rstats) equivalent i should upgrade to?

๐Ÿ“Š Data update: We've just updated to the 2025 release of the OECD Government at a Glance dataset.

It has general government spending data up to 2024 and spending by function data up to 2023.

has anyone written a nice review or summary of Bayesian approaches to causal inference? most of what I'm aware of is focused on frequentist approaches, or implicitly frequentist (caring about bias, ignoring variance); and methods which may not translate easily to the Bayes world (e.g. weighting)

A causal diagram. Z points to A which points to Y. There is a U that points to both A and Y. So A has unmeasured confounding, but Z is a valid instrument for A on Y

It's a musical #MEstimatorMonday (25/52) since we will focus on *instrumental* variables (IV)

IV analysis is nice because we can get around unmeasured confounding (at the cost of a more easily interpretable parameter)

If you get an answer, will be interesting to see whether mixed effects models are considered as part of the solution. They should. I doubt that this has been looked at.

Is there a good paper that thinks carefully through how to apply the rubin causal modeling framework to within-subjects experiments? I always feel like I am doing a lot of hand waving when asserting causality for those designs.
