@Prashant_Garg_ There currently is no title "Assistant Professor" in the Oxford system. So even if hired fresh from PhD you become an Associate Professor.

@instrumenthull If there exists a function f(Y) such that E(f(Y)|Z,W)=k(W), then I believe you are done (just set h(Y)=f(Y) and use your completeness assumption above). But something tells me that this is not the condition you are searching for. :)

Just checked my LinkedIn feed for the first time in a while --- way more interesting than Bluesky, way less noisy than X. Maybe this is the place to be?

This week we marked 40 years of unit roots & cointegration with a workshop hosted by the Oxford Bulletin journal. Yesterday, we enjoyed a panel discussing the key concepts and results of cointegration analysis developed over 4 decades. #UnitRoots #Cointegration #EconConference

Two insights from Economics: 1 Markets are flawed. 2 Government allocation is often worse. Two insights for research assessment in Economics: 1 Journal rankings are flawed. 2 Replacing them with something else is often worse. (this post is not about SQARE but about DORA!)

Today is a sad day as I have learned of the passing of my friend and @usc_econ colleague University Professor Richard Easterlin. Here is a happy photo of us back in 2018. Dick would have turned 99 in January. He was a highly productive and optimistic economist. A thread.

Detecting a clear structural break in social network migration over recent days. The process appears non-stationary with a strong upward trend. We might finally be observing that long-anticipated regime shift in platform adoption.

Logged into Bluesky for the first time in months, and it’s amazing to see the momentum building and the community growing! If this keeps up, we might all be able to close our Twitter accounts soon. Find me on Bluesky: @weidnerecon.bsky.social #Bluesky #SocialMediaShift
