🧵 (1/4) There are four fundamental flaws of the House tax bill.

#1 It is fiscally irresponsible; all reputable sources agree. Bond markets & downgrades show US financial fragility; this is a bad time to take on trillions in additional debt toward no useful policy rationale.

Thanks Ludovic! Below is a first breakdown of the pesticides embedded in EU consumption/imports. Some of those forbidden substances are produced in Europe, see www.lemonde.fr/planete/arti...
Tracking the whole chain is on the todo list!

5/ We evaluate two policy instruments with distinct WTO compatibility considerations: (1) a Leakage Border Adjustment Mechanism designed to neutralize competitive distortions, and (2) a Phytosanitary Border Adjustment Mechanism which prices pesticide externalities in imports.

4/ We introduce the "phytosanitary footprint" metric to quantify the aggregate pesticide load in agricultural production. This methodology enables assessment of transboundary environmental impacts embedded in trade flows, similar to carbon footprint accounting.

3/ Quantitative modeling demonstrates that implementing a unilateral 50% pesticide reduction policy (e.g., Farm-to-fork) without complementary measures would significantly impair EU agricultural competitiveness while facilitating production displacement to regions with less stringent standards.

2/ Without safeguards, stricter EU regulations not only fail to achieve global environmental goals but actively tilt the playing field against EU farmers.

4/ Key to understanding this issue is the "phytosanitary footprint" - similar to a carbon footprint, it measures the total pesticide load used (directly & indirectly) in producing agricultural goods. It reveals environmental impacts that cross borders through trade 👇

1/ 🚨 NEW: 46% of the pesticides embedded in EU agricultural consumption come from imports—despite imports making up just 17% of total consumption. Many of these include substances banned in the EU 🇪🇺

This regulatory gap fuels leakage effects and hurts EU competitiveness 🧵👇

French organizations Carbone 4 + ECF launch this essential report on "imported emissions".

It's essential because a significant part of global emissions are embedded in trade and interdepencies, raising questions about responsibilities and partnerships for climate.

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.

My Trade Secrets today. When Trump replaces Biden, America’s trading partners fear he will impose high unilateral tariffs, treat WTO rules with contempt and coerce them with threats of trade restrictions.

“No change there then” would be an exaggeration, but not a grotesque one.

Here is my attempt to systematically think through possible consequences of new Trump tariffs

Suppose US imposes 20% tariff on all goods imports

Effect 1: higher prices for goods imported into US. This hurts US consumers by raising living costs 1/
