What Moved & What Held
Coming in, the standing view was: task‑level productivity gains from AI are common but uneven and depend on complements like skills and data, rather than being general across contexts; adoption, not exposure indices alone, predicts early labor‑demand shifts; and workers with AI skills disproportionately capture gains.
This week adds clean causal evidence that generative AI expands what early‑career, middle‑skilled workers can do without immediate comprehension loss, and that AI‑mediated disclosures change investor engagement and price reactions; at the same time, new measurements indicate verification costs and governance frictions constrain delegation, and hiring demand in high‑skill immigration appears to shift toward AI‑builder roles while investment shocks were associated with lower employment in lower‑software‑skill jobs. Still holds this week: gains remain context‑dependent and concentrated where complements exist, and near‑term quality/productivity improvements show up at the task level rather than as a universal aggregate surge.

Task Expansion with Generative AI: Experimental Evidence on Middle-Skilled, Early-Career Workers
Hanna Brosch, Christina Langer, Philipp Lergetporer, Sandra Mueller, Harald Pfeifer, Nele Tschoepe
RCT, high evidence
In a preregistered field randomized controlled trial in Germany (N=673 apprentices across 12 vocational schools), access to generative AI raised productivity broadly and by 26–31 percentage points on tasks outside formal training, with the biggest gains where baseline performance was weakest and larger effects for higher AI literacy.
So what: If this holds, staffing and training models that assume narrow junior scopes risk materially understating near‑term productive capacity in similar settings.

Enhancing Corporate Communication with AI-summarized Disclosures
T.J. Wong, Yang Yi, Gwen Yu, Shubo Zhang, Tianyu Zhang
RCT, high evidence
A firm‑call–level randomized field experiment in China shows providing AI‑generated annual‑report summaries increases both the number and quality of investor questions and amplifies capital‑market reactions, including spillovers beyond summarized content.
So what: If this generalizes, price discovery and who benefits from disclosure may hinge on AI‑mediated formats, raising information‑access and fairness risks around call design.

RCT, high evidence
In two undergraduate courses (846 submissions), AI graders reproduced rubric scoring at scale but graded 0.68 points lower than humans on a 5‑point scale, students could not reliably detect grader identity, and satisfaction tracked perceived human grading rather than actual grader.
So what: If this holds, scaling AI grading risks a gap between recorded performance and student satisfaction.
