We can also capture hard-to-quantify characteristics such as aesthetic similarity captured by images and functional benefits mentioned in reviews. Finally, our method can be scaled very easily across categories.

👉 What are advantages of our approach? We side-step the need define which product characteristics are relevant in a given category and instead extract information from product descriptions and reviews which likely mention the characteristics most important to consumers.

👉 Does this work well? In an online choice experiment we show that our approach predicts second choices better than characteristics-based models and it predicts substitution pattern well in real-world data across 40 product categories.

👉 What do we do? We propose an approach to extract product information from unstructured text and image data that we then use as an input for a mixed logit demand model.

For those attending #ASSA2025, come to our session on ML/AI + unstructured data (e.g., text and images).

We'll have a couple of papers on the econometrics of it, and I'll talk about incorporating this type of data in demand estimation.

It's Sunday Jan 5 at 10:15 AM.
