One big and very recent development is the #ergodiciity theory in #economics. It throws things like the entire #behavioral economics to the bin and shows how rational the people actually are, confirmed experimentally. All of the taken out of the butt utility functions disappear. It's very satisfying to read.
The foundational paper:

But again, it's #microeconomy, way less political area. I'm personally most familiar with the market microstructure field. If you wanted something not very political, try those keywords. It's most connected to the mathematical decision theory, the PvE version of game theory, which is PvP.
The ergodicity problem in economics - Nature Physics
This Perspective argues that ergodicity — a foundational concept in equilibrium statistical physics — is wrongly assumed in much of the quantitative economics literature. By asking the extent to which dynamical problems can be replaced by probabilistic ones, many economics puzzles are resolved in a natural and empirically testable fashion.
