If you have a policy area you like you might start there. From my lens, here are some interesting ways to look at political economy from a broader point of view: economic disruption from AI (could be from energy prices, labor substitution, and lots more), climate modeling and its impacts on economies, conservation and ecosystem stability, and economic growth under different levels of inequality. I would add this to the mix even though it isn't a typical economic area: geopolitical destabilization from autonomous weapons, both physical and cyber.

Those are definitely all areas of interest for me as well. Thanks for the pointers. Do you write anywhere?
