Thanks a lot Mathieu! I wasn’t expecting such a high share from Mercosur countries, this is important given the trade deal between the two blocs…

Thanks a lot, that’s interesting. Out of curiosity, which countries does the EU import pesticides/forbidden pesticides from?

🇪🇺New VoxEU column‼️
🚨We show that a 50% reduction in imports of critical inputs from China and China-aligned countries would lead to transitory value-added losses in manufacturing of about 2-3%.

🇧🇪🇫🇷🇮🇹🇸🇮🇪🇸We find significant variation of such a shock across firms, sectors, regions, and countries.

And more international trade economists that listed there Mastodon handle in their RePEc profile:

Our brand new paper. Feel free to check it out!

Our finding: markup adjustments dampened the aggregate productivity cost of the 2012 Italian earthquake by ~30%.

This mechanism matters!

What’s the overall effect of markup adjustments on the economy?

We calibrate an oligopolistic model to firm-level data: firms hit in the model are those hit in reality.

What’s the story?

NDs ⬆️ marginal costs, pushing firms to charge higher prices. But higher prices mean losing market shares - so firms cut markups to stay competitive.

How about agg. productivity? The effect of disasters depend on which firms are hit (more productive or not)!

Our finding? Larger firms hit by these shocks reduce their markups - and the drop is persistent!

We study one channel through which firms adjust: markups.

Using 15 years of micro data on Italy's manufacturing sector, we examine the impact of costly events like earthquakes & floods 🌊.

Economic activity spans many locations. So, if a flood hits 🚗 producers in a region, market shares might shift to unaffected producers in another one.

In short: location-specific shocks can reallocate activity, impact misallocation, and shape aggregate productivity!

Natural disasters are costly - but firms don't just stand by. They adapt and respond.
How do they do it? What are the macro implications?

In our new paper with @fpconteduca.bsky.social, we look into that. A 🧵 (1/7)
