Graph of the Bilateral Trade in Services (BiTS) database coverage. While trade debates focus on tariffs and goods, services have quietly defied deglobalisation and become an increasingly important driver of growth. Services trade not only generates productivity spillovers and labour-market gains, but it is also where future policy tensions could emerge. Yet services trade remains under-measured and under-studied. This column introduces the new Bilateral Trade in Services (BiTS) database, which tracks services flows between countries over time and at the detailed sector level. It documents a declining distance elasticity for services trade in recent years, which is driven by the growing importance of less distance-sensitive service categories.

The analysis in our chapter is based on a new database on bilateral services trade which we have been compiling for the past year. We expect to publish it for others to use later this summer.

However, it appears that trade in modern services (the fastest-growing portion of international services trade) is most vulnerable to geoeconomic fragmentation. This could emerge as a headwind for services globalisation going forward.

We find that - in contrast with goods trade - the answer is: no (so far!).

My colleague Nan Li and I contributed a chapter on services trade. We ask: is there evidence that geopolitical alignments are reshaping bilateral trade in services? (In IMF parlance: is there “geoeconomic fragmentation” in services?)

📈IMF April WEO📉:
2025 global growth forecast would have been 3.2% pre-April 2 (down just 0.1 from January). It is 2.8% given the post-April 2 trade policy announcements. Even if all “tariff pauses” become permanent, global growth remains at 2.8% (but differently distributed across countries).

I stand corrected. The formula is not deficit/imports. The formula is surplus/(imports * ε * φ), where ε = -4 and φ = 0.25. That happens to equal deficits/imports.

🚨New data alert!

A beta version of the Global Tariff Database is now available! 🔗https://feodorateti.github.io

🔎If you're looking for cross-country data on bilateral tariffs, this might help you.

Today marks the 180th anniversary of the birth of great Irish/Oxford economist Francis Ysidro Edgeworth.

Most remembered now by students for the Edgeworth Box, he was the founding editor of the Economic Journal and is buried less than 400 feet from the Economics Dept with a beautiful Celtic cross.

Modern supply chains don't look like trade theory 101!

They involve constant border crossings, each now hit by tariffs.

Tariffs raise prices, but the more important thing they do is disrupt supply relationships.

Conventional wisdom seems to be that for many important services (think tourism!) the exporter has much better information about the extent/value than the importer.

Unlike with goods, there is no customs data on which to base services trade statistics - just firm surveys, the methodology of which may not be consistent across countries. And the extent to which they capture the “truth” may not be symmetric between the importer and exporter.

“That will require transformational reforms to lift productivity. In many countries, resources—including workers and capital—simply aren't flowing to the most dynamic firms, dragging average global productivity growth down by 0.6 percentage points annually.” www.washingtonpost.com/opinions/202...
