No shit, Sherlock.
The World Cup is averaging 3.1 goals per match so far, the highest since 1958. Will likely regress some, but lopsided matchups like Germany-Curacao will contribute to it. Generally speaking in international soccer, the bigger the talent differential the more scoring there is.

Define "any of us"
This shows the top econ authors by solo top 5 equivalents per person (i.e. papers count for 1/N_authors). Of course this is a deeply imperfect measure. There are lots of great papers outside the top 5, and some authors contribute more to a paper than others. But it's probably about as good a measure as we can hope for to judge someone's probable lasting impact. And I find it extremely reassuring. I don't know if I'll ever get to 4 solo top 5 equivalents, but it certainly feels possible. That any of us could make it to the bottom of this list means our profession is not quite as segmented as you might think.

1 year ban from seminar attendance for those who fail to ask the “how is this economics?” question before the presenter moves on to slide 2.
1 year arXiv ban for those who don't clearly state their research questions within the first 5 paragraphs of the introduction.

There is a difference between citing articles you have not read and citing articles that do not exist. And we cannot justify one faulty practice by analogy to another, arguably lesser, faulty practice.

There is quite a bit of high-frequency movement in agricultural input and output prices these days, so sometimes it is helpful to zoom out a little. These graphs show MoM and YoY changes in key fertilisers and cereals as of April 2026.

This is, probably, my favourite.
