Extremely thrilled to see my new paper titled "Parental Educational Attainment and Child Labor: Evidence from Malawi" published open access in the Journal of Agricultural and Applied Economics.

A year ago on Facebook, at the request of a former MSU student, I made this post. I used to say in class that econometrics is not so hard if you just master about 10 tools and apply them again and again. I decided I should put up or shut up.

The Geometry Behind Maximum Likelihood Estimation (MLE):

Maximum Likelihood Estimation (MLE) has a rich geometric interpretation that views statistical models as curved surfaces embedded in high-dimensional probability spaces. Each parameter value corresponds to a point on a statistical manifold, and the likelihood function defines a landscape whose peaks represent the most plausible explanations of the data. Gradients and Hessians of the log-likelihood describe local geometry, while the Fisher information acts as a Riemannian metric, measuring how distinguishable nearby distributions are. From this perspective, MLE becomes a problem of finding geodesic directions of steepest ascent on a curved surface rather than in flat Euclidean space. In statistics, this geometry explains efficiency, curvature bias, and asymptotic normality. In machine learning and deep learning, natural gradient methods, information geometry, and mirror descent exploit this structure to accelerate training and improve stability. The geometric view reveals that learning is not just optimization, but navigation on a curved space of probability models.

Let's discuss different DiD estimators with unbalanced panels -- often due to missing data on Y, or attrition. I will use the Stata commands csdid and jwdid as part of the discussion. First, a review. Assume time-constant covariates, X and a balanced panel.

I recommend both books, to be read simultaneously. The first, for breadth of coverage, the second, for clarity -- free of the cognitively opaque notion of "potential outcome". @KirkDBorne

gander is an R package that brings AI directly into RStudio or Posit.

Instead of switching between your IDE and a chat window, gander lets you ask questions or request code changes right inside your script. It automatically shares relevant context such as variable names, data types, and the surrounding code, so the model can provide precise answers without extra copy-pasting.

You can trigger it with a simple keyboard shortcut, choose from different AI models (OpenAI, Claude, or local ones), and control how much of your data is sent for context. In short, gander makes working with AI in RStudio smoother, faster, and smarter.

Take a look at the visualization below. It shows an example of how to use gander to create a ggplot2 graph. It’s taken from the package website: https://t.co/DbsZTbsmVK

I’ve started an ongoing project to collect all the datasets which economists can use, all in one place, organized by topic. Started with 50, further suggestions are extremely welcome. It will grow considerably.

[Bryan Hardy @BryanHardyEcon]

Great initiative! For macro/finance/international topics, we’ve assembled a number of links to different datasets (as well as code and other resources) here:

The NBER IFM data page is another great resource.

Tired of referees saying your standard errors are wrong?

This survey will help you understand if you really have a problem — and, if so, how to fix it!

@TheImmortalKop Ekitike is a €60M player max. Isak was more complete at 22 especially with influencing big games. This is a massively risky signing for LFC. Would rather spend on both Watkins and go all out for Isak if selling Nunez, Chiesa, and Diaz.

[Melissa Dell @MelissaLDell]

Neural networks (e.g., LLMs) make often imperfect predictions, introducing biases into analyses that rely on them. Common empirical economics scenarios fall outside the existing literature on debiasing “black-box AI”. Our paper (with @J_S_Carlson) on robust and efficient inference with unstructured data (e.g., text, images) provides a unifying theoretical framework, relates inference with text/images to familiar problems like causal inference, develops new insights into efficiency, and provides practical guidance on common empirical scenarios. https://t.co/FQdVMuLpl0

[Eric Abaidoo @EricAbaidoo]

@LFCTransferRoom @valterdemaggio Selling Nunez alone can get us close to Osimhen’s release clause. Then they have to negotiate separately for Chiesa. This deal doesn’t make sense.
