Table talk — what is the best new work in economics?

This is a thread I would love to see expanded upon.
I often lament the fact that economists are so unwilling to be publicly
enthusiastic about new ideas. I realize that there is a cost to backing
the wrong horse but when interesting ideas are being worked I think there
is value to dissemination even if they fail to pan out. With that in mind,
whose work in particular prompted #4?

I’m surprised that no one is talking about Experimental Economics. There is some exciting work in Game theory on making somewhat less ad hoc eq refinements, and the like. Particularly some new notions of fairness and why it is that actors take suboptimal actions.

Also, theres some interesting computational work on the distant hirzon, nothing there yet, but Ken Judd has some interesting thoughts, and programmatic solutions may help address problems for which there were no equilibria.

Arrow has been really interested in complexity work (a la Santa Fe) that may really go somewhere eventually.

Those I think could really advance the field. Theres also gret new stuff that might not advance economics, but uses economics to make life better. Theres a David Card paper lately that is the first good treatment of what happens when you raise the minimum wage.
