Fifty Years of IO in Agricultural Economics: Evidence, Evolution, and Emerging Directions
Over the past two decades, industrial organization (IO) research within agricultural and resource economics (ARE) has gained substantial influence. We document

How did we do this?
Web scraping with python to extract text
LLMs (GPT-4.1-mini + embeddings) to classify themes, extract topics and methods.
Google Scholar and Web of Science for citations
Shows what ML/AI can do for meta-research:
→ scale, and insight extraction

What do the experts think?
Top takeaways:
• Econ IO is highly respected; methods and Econ journals appreciated as gold standard.
· However, field is distinct. Its impact and uniqueness maybe underappreciated!
• Big appetite for upstream IO, climate policy, and machine learning

Why the rise in IO in ARE?
We ran regressions on 5,000+ IO papers. Here's what correlates with citations (Google Scholar and Web of Science):
(+) Practical relevance
(+) Applied, policy-facing work
(-) Structural modeling

Publications:
IO in ARE is growing.
Food Policy, AJAE, JARE among others.
30%+ of ARE journal output is now IO-flavored.
And citations? ARE journals are climbing the ranks.
Food Policy is now #1 by median IO citations.
August 6, 2025 at 8:39 PM
Methods:
Today, 95% of IO in ARE is empirical.
But mostly reduced-form + descriptive.
Structural models? Shrinking.
Meanwhile, IO econ is doubling down on structural

Themes:
IO in ARE has steadily shifted focus:
From upstream issues like grain markets & coops
→ To downstream topics: food retail, nutrition, labeling, climate, & resilience.
Consumer-facing policy issues now dominate.

We asked 5 questions:
What has IO in ARE studied?
What methods have been used?
Where has it been published?
How influential is it?
Where is IO in ARE going?
August 6, 2025 at 8:37 PM
Key result: IO in ARE is now more influential than ever. The fraction and volume of IO papers in ARE journals keeps growing fast. They receive a large volume of citations.
IO papers in ARE journals now receive comparable or higher citations than those in leading IO econ journals
