🚨Job market paper🚨 Container ships are vital for global trade & large emitters of CO2. What happens when we tax their emissions? Check out my JMP: Can Unilateral Policy Decarbonize Maritime Trade? Paper: https://t.co/l9xuRHVZdf Website: https://t.co/PxrV45mqfe #EconTwitter 1/10

Take-away? Good climate policy anticipates strategic responses from oil producers. This paper shows how understanding #MarketPower can help policymakers turn #decarbonization into opportunities for global welfare gains.🌍🌎🌏 (10/10) @LeuvenEconomics

So, what’s the optimal #CarbonTax? 1️⃣ Start slightly lower than the social cost of carbon. 2️⃣ Increase faster than the social cost of carbon to capture those additional welfare gains. (9/10)

Compared to a flat tax, an 📈increasing carbon tax 📈heavily reduces inefficiencies. By reallocating market share to lower-cost fields, it achieves a win-win for emissions and welfare. (8/10)

Why? Under OPEC’s market power, production is withheld from the most efficient fields. Anticipation of stricter carbon policies erodes this distortion, leading to large welfare gains as production shifts toward efficient producers. 🌍 (7/10)

What do I find? 1️⃣OPEC exerted market power from 1990–2019 but didn’t fully exploit it. 2️⃣Carbon taxes can accelerate short-term production (green paradox). 3️⃣BUT under imperfect competition : Taxes also reallocate production, reducing inefficiencies and boosting welfare. (6/10)

To get this answer, I build and estimate a dynamic structural model of global oil production. Using micro-level data, I capture OPEC's balancing act: ⚖️slow production to boost prices today ⏬ ⚖️OR pump faster to avoid future losses from stricter policies ⏫. (5/10)

My JMP dives into this tension. Main takeaway: increasing carbon taxes don’t just cut emissions—they rewrite the rules of the oil market. Production shifts to efficient fields, curbing OPEC’s dominance and paving the way for a more efficient transition.. 💡🌍 (4/10)

Meanwhile, #OPEC ⏬slows down⏬production to keep prices high, exercising market power by creating artificial scarcity. This creates a tension: 👉How does OPEC’s behavior interact with climate policy? 👉Can policies tackle emissions and reduce market distortions? (3/10)

To align with the #ParisAgreement’s global warming target, an important portion of world oil reserves needs to remain untapped. The prospect of stricter climate policies can lead oil companies to ⏫speed up ⏫ production today—a phenomenon known as the green paradox. (2/10)
