What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-LOC-2026-001 · Evidence A · P1

A staged improvement in eBay English-Spanish machine translation reduced search friction and increased completed cross-border trade, but quantity and revenue effects were not identical.

What this does not establish

This is marketplace purchase/sales evidence, not click, ad-attitude, comprehension or retention evidence. It is specific to eBay's English-Spanish search/title translation and US-to-Latin-America trade; it does not establish the same effect for full product-page translation, other language pairs, independent stores, margins, refunds or repeat purchase.

Counterevidence & uncertainty

The revenue lift (13.1%) is smaller than the quantity lift (17.5%), and heterogeneity contradicts a universal translation uplift across products or buyers.

What would change the reading

Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral, commercial or welfare outcomes.
