Arne, Fernando, and I are happy to share the updated version of the “jwdid” command for heterogeneity-robust estimations with non-linear outcomes and high-dimensional fixed effects, along with the corresponding paper. We hope it is useful. ideas.repec.org/p/drx/wpaper...

Happy to see our survey on #sanctions with @gfelbermayr.bsky.social, Cliff Morgan, and Costas Syropoulos published at the Annual Review of Economics. go.shr.lc/3Rtj9dP

So looking forward to our Global Ecoonomic Networks Workshop next week at Lake Como! The exciting program is now availbale via: sites.google.com/site/peterep...

Good news on trade. Arne, Mario, Philipp and I construct a dataset on ‘trade specialists’. We find that the trade costs for the specialists are four times lower than for non-specialists. The corresponding welfare gain from globally efficient trade is 80%!

@kevinhorourke.bsky.social & Roger Vicquery introduce a new index of global exchange rate fixity and find that global anchoring to the US dollar fell sharply after 1971, and global exchange rate fixity is now only about one-third of the Bretton Woods level. cepr.org/voxeu/column... #EconSky

📢NEW DATA! Happy to share the new release of the International Trade and Production Database for Estimation - ITPD-E-R03. Thanks to my co-authors Mario Larch & Serge Shikher and to the USITC! For details: ideas.repec.org/p/drx/wpaper... Enjoy the data and have a great summer!

Sloppy headline. Of course, they were down in April -- because they were WAY up in March ahead of the (potential?) tariffs. It even goes on to say "However when compared with April 2024, goods exports were still up by €2.5 billion." Sorry to spoil your story with your OWN story.

Using a new data on international and domestic languages, we argue that having a uniform language within a country leads to significant welfare gains, however, the gains from bilingualism are even lerger.

Thanks for all your valuable service to the profession!

RePEc has no staff, thus we rely on volunteers and some self-help by users: publishers index their works, authors maintain their online profile, so that volunteers can take care of the rest. Thanks for doing your part. repec.org #RePEc #EconSky

It was an honor and a great pleasure!

Javier Flórez (@pseud0safari.bsky.social), Mario Larch, Sebastien Bradley, and I are very happy share the update of the most disaggregated dataset of consistently constructed international and domestic trade flows -- GRANTPA. So, let’s estimate GRAVITY with GRANTPA. ideas.repec.org/p/drx/wpaper...

🚨🚨Good news for the EU! The great Lionel Fontagné & I propose new measures of the potential of trade blocs. An EU application shows that the EU has been very successful, but only half of the potential gains from the EU have been realized to date.👇 ideas.repec.org/p/drx/wpaper... ‪@ec.europa.eu‬

Two sad news for science this weekend: 1. The (allegedly) fraudulent paper by the MIT student 👇 thebsdetector.substack.com/p/ai-materia... 2. And the revelation that one can buy citations at Google Scholar 👇 arxiv.org/abs/2402.04607 On the bright side ... I am going fishing

Despite the current challenges and prior doubts regarding the ability of GATT/WTO to promote international trade, the evidence from our meta-analysis is that the WTO/GATT effects on trade have been positive and significant. Happy 30th anniversary & thanks, GATT/WTO! ideas.repec.org/p/drx/wpaper...

🚨 GRAVITY for UNDERGRADS🚨 Very happy to share “Gravity for Undergrads” - a Chapter, designed to introduce the gravity model to undergrads and novices in trade. It comes with data and code in Stata & R. I hope it is useful. Gravity rules 💪 yotoyotov.com/Gravity_Unde...

🚨NEW COURSE🚨 Want to learn how to quantify the partial and general equilibrium effects of trade and other policies (e.g., tariffs, sanctions)? If so, consider taking my course on trade policy analysis with structural gravity. For more information visit: yotoyotov.com/gravity.html

A great threat on tariffs by one of the best trade economists of our time. Thanks, John!

I'm seeing a huge spike in interest in tariffs from people who normally don't work in the economics of international trade. Here are a few useful things to know about them. (1/14)

For no particular reason, it might be a good time to repost my Starter pack of academic economists who study international trade go.bsky.app/G3dqAYg

“there is little room for trade cost asymmetries to lead to bilateral trade imbalances except in certain sectors (e.g., Mining and Services), where modeling the direct bilateral trade costs… can be improved” @yotoyotov.bsky.social @gfelbermayr.bsky.social 2021 www.sciencedirect.com/science/arti...

In this paper, G. Felbermayr and I find that 88% of the variance in bilateral trade imbalances is not due to asymmetric trade costs (e.g., tariffs, NTBs, etc.). Thus, it is perhaps not correct/fair to use bilateral trade imbalance to calculate asymmetric trade costs. cepr.org/voxeu/column...

Happy to see our "Gravity in Transition" paper with Jim Anderson published (open access) in a Special Issue for the great Jeff Bergstrand at the Review of International Economics. Gravity rules 💪 onlinelibrary.wiley.com/doi/10.1111/...

Who will be the first to write the history of that short-lived period that began in 1989 and ended in 2025? So much hope and opportunity, so much short-sighted and incompetent leadership on all sides, and such an ugly, tragic ending.

Very happy that our paper with Jim Anderson, where we propose simple methods (interval-pair fixed effects) to estimate #gravity from the short to the long run is accepted in a SI in honor the great Jeff Bergstrand! 🙏 Editor Scott Baier! Gravity Rules 💪 ideas.repec.org/p/drx/wpaper...

Call for papers for the Second Annual Workshop on Sanctions! Consider submitting your paper on sanctions before the February 28 deadline at buff.ly/4bc3atC, and we hope that you will join us at the WIFO institute in Vienna on May 27.

It was a great pleasure and a privilege to deliver a keynote on the evolution and consequences of economic #sanctions at Lewis and Clark. I had stimulating discussions with excellent students and great colleagues. Thanks Anna Miromanova for the invitation and the hospitality!

The Drexel Center for Global Policy Analysis hosted the inaugural (and very timely!) Philly Trade Group workshop with excellent presentations on sanctions, innovation, and geopolitics by Jin Liu (UPenn) and Ohyun Kwon (Drexel), and an exciting keynote by the brilliant Bob Staiger (Dartmouth).

New at JIE: "The Empire project: Trade policy in interwar Canada" by Markus Lampe, Kevin Hjortshøj O’Rourke, Lorenz Reiter, Yoto V. Yotov (@yotoyotov.bsky.social) https://doi.org/10.1016/j.jinteco.2024.104024

Because of very important differences in their definitions, types, purposes, implementation, and outcomes, tariffs should not be confused with sanctions … Well, until Donald Trump redefined tariffs as “Sanctions with Revenues” – the best of both worlds.

📢NEW DATA! Aleksandra, Costas, Erdal, Gabriel, Heider, Ohyun & I are happy to share the new Global Sanctions Database (GSDB), including 1,547 sanctions, 1950-2023. We also estimate the effects of the sanctions on Russia. For details see ideas.repec.org/p/drx/wpaper...

Attention PhD students, postdocs, prof. economists! We will have our first Nottingham International Trade Summer School this summer! Lecturers: Arnaud Costinot and Andres Rodriguez-Clare Dates: 30/6 to 5/7 Registration open! www.nottingham.ac.uk/gep/news-eve...

After years in the making, I am happy to share a new guide for gravity estimations. Our recommendations are motivated by trade theory, but most of them apply broadly, e.g., to migration, FDI, etc. Mario Larch, Serge Shikher, & I hope this is useful. Gravity rules 💪 ideas.repec.org/p/drx/wpaper...

Our survey on #sanctions was accepted at the Annual Review of Economics. Thanks to my amazing co-authors @GFelbermayr, Cliff Morgan, and Costas Syropoulos for this interdisciplinary collaboration. I learned a lot. I wish a healthy and happy 2025 to all!🍾 ideas.repec.org/p/drx/wpaper...

It was a true pleasure and a privilege to teach a gravity module in the Ph.D. trade course of Prof. Grossman at Princeton. Thanks so much, Gene, for this amazing opportunity! Gravity rules 💪

Next stop: full Schengen accession. We welcome the decision of the Council of giving green light to Romania and Bulgaria to fully join the Schengen family.

I have written a review of the recent literature on "Multiproduct Firms in International Trade" for the Oxford Research Encyclopedia of Economics and Finance. Access it here: doi.org/10.1093/acre...

NEW DATA! Very happy that ITPD-S is now public (& free)! For the first time, we have consistent datasets (ITPD-E & ITPD-S) that can be used for estimation and simulation of trade policy effects. Ingo, Mario, Serge, and I hope it is useful. Gravity rules💪 www.usitc.gov/data/gravity...

Curious by what a new 400% tariff on China would do, I used a GE gravity model and new data from USITC to simulate the impact of various tariffs on China (with retaliation) on real expenditure in the US. Relative to the 60% tariff, a 400% tariff does very little. So, make it a 1000%! Gravity rules 💪
