I'm giving a brownbag seminar on "Accounting Research in the Twenty-First Century" at NC State University today, and I have summarized the talk for everyone else with this handy graphic...

Boardroom suggestion meme, three panels. A boss tells the meeting: "We need to increase the credibility of accounting research." Three researchers suggest: "More fixed effects," "More matching," and "Careful design." In the last panel, the one who said "Careful design" has been thrown out of the office window.

The 📦 `wrds` dev version displays the official product names for a more human-readable version of the table names. The package now comes with a #rstats #pkgdown site: statzhero.github.io/wrds/news/in... All that's missing is a hex sticker? Send ideas.

What’s going on in this chart? Accounting and finance sit in a strange upper-right quadrant: jobs are available, but fields are highly exposed to AI. Are firms just slow to adapt, or do entry roles fulfill a different purpose vs. IT? Gift link below: www.economist.com/finance-and-... #AI #jobs

Hell yeah @zotero.org

Coming less than three months after Zotero 8, Zotero 9 is the first major update since we announced a faster release cycle for Zotero, and it represents our commitment to getting stable features into the hands of users more quickly.

@paulgp.com where do the 70-90% identification rates from the dashboard website come from? I can't find them in the paper (or I'm reading it wrong). paulgp.com/econlit-pipe...

This is live on the official IRS website and hasn't been fixed in a year.

A table titled "Yearly average exchange rates for converting foreign currencies into U.S. dollars" showing one row for the Euro Zone. The Euro averaged 0.886 per U.S. dollar in 2025, 0.924 in 2024, and 0.924 in 2023. The 2024 value (0.924) is circled in red, highlighting a comma instead of a decimal point.

So confident, so wrong. I'm actually not sure why ChatGPT gets this basic #RStats behavior wrong.

$Predict the output here: x <- c("a cat", "concatenate", "cat!") grep("\\bcat\\b", x, value = TRUE) character(0) Reason: in base R’s default regex engine, \b is a backspace, not a word boundary. So "\\bcat\\b" doesn’t match anything in x.$
