All courses in this year’s CEMFI Summer School look terrific. Applications are still possible for some of them, including — purely coincidentally — one taught by yours truly on the Economics of Global Value Chains. Come join us in Madrid!

I visited the University of Basel last December and sat down with Rolf Weder to discuss several aspects of my research and of global trade. A lot has changed in the last 4 months, but some of what I say may still be of relevance😅 Link to the interview: innoscape.ch/de/publikati...

9/ Key takeaway: Production length is an important but overlooked aspect of production and firm behavior. We hope that our measure will find broader applications across fields.

Pol Antras @pantras.bsky.social · 13/02/2025

8/ The negative relationship between APPs and capital costs holds across countries and industries. Even in sector-specific regressions, most industries show a similar pattern.

100

Pol Antras @pantras.bsky.social · 13/02/2025

7/ Extending the analysis worldwide: APP rankings are highly correlated across countries. Some industries naturally require long production periods, regardless of where they are carried out.

100

Pol Antras @pantras.bsky.social · 13/02/2025

6/ Industry correlations: Higher APP industries tend to be more skill-intensive but less physical capital-intensive. This suggests an interesting dichotomy between working capital intensity and physical capital intensity.

100

Pol Antras @pantras.bsky.social · 13/02/2025

5/ Since 2006, APP in U.S. manufacturing has risen as the cost of capital has fallen. Our regression results suggest that about 19% of this increase is due to cheaper borrowing costs.

100

Pol Antras @pantras.bsky.social · 13/02/2025

4/ Across industries and countries, APP is remarkably stable. Industries with complex production processes (e.g., pharmaceuticals, distilleries) have longer APPs, while perishable and commodity producers have shorter APPs.

100

Pol Antras @pantras.bsky.social · 13/02/2025

3/ Using firm-level data from various countries, we confirm a key theoretical prediction: firms facing a higher capital costs feature shorter production periods. As interest rates rise, firms shorten their production lengths.

100

Pol Antras @pantras.bsky.social · 13/02/2025

2/ APP is defined as a weighted average distance between the time a firm employs its inputs and the time these inputs deliver finished goods. In steady state, APP turns out to simplify to the ratio of inventories to the cost of goods sold (COGS). A simple yet informative metric!

Pol Antras @pantras.bsky.social · 13/02/2025

1/ 📢 New paper alert! 📄 Together with Vitalii Tubdenov, we propose a measure of the "Average Period of Production" (APP) to capture the temporal dimension of production processes. It is inspired by Böhm-Bawerk’s capital theory.

What would be the impact of Trump's announced 25% tariff on all steel and aluminium imports? Lydia Cox's (coxlydia.com) job-market paper, now an R&R at the American Economic Review, provides good guidance. Latest version is here (coxlydia.com/papers/cox_s...).

There's been a lot of debate about what economic theory says regarding tariffs. Drawing on my research with quantitative economic models, here's a thread explaining the textbook logic for why "tariffs are bad" for revenue generation. 🧵 Let’s dive in!
