New econ insights on polycrisis:
💡 NEW WP💡 with Ottmar #Edenhofer takes #RiskManagement perspective on #NaturalCapital & #ClimateEconomics & their interlinkages. We propose new policies to harness financial markets 4 risk sharing & discuss institutions 4 implementation 🌍🦋📈🏛️

Non-permanent carbon removals #CDR, like afforestation, cannot compensate for emissions as permanent ones can. This should be reflected in #CarbonPricing.
PIK study in Environmental and Resource Economics provides guidance, calculates the price difference.

Für alle (sorry folks, German only), die noch keine Georgisten sind, hier einen spannende halbe Stunde zu einem Thema, über das alle lernen sollten:

New work lead by Martin Hänsel with other colleagues from @pik-potsdam.bsky.social. Germany's gas price brake winter 2022/23 may be "a blueprint for climate policy, where policy makers often struggle with carbon pricing due to its distributional impacts."

8/ 🌍 Curious about the details? Read the full study here: authors.elsevier.com/sd/article/S... Let’s talk about effective policies for sustainable diets! #ClimateAction #FoodPolicy
7/ 🤔 Note: We couldn’t include meat substitutes like soy or seitan in our analysis due to data limitations.
6/ Cf. @s-stantcheva.bsky.social post shorturl.at/Zw127: Public acceptance is possible if there's clear communication that 1) the approach is effective in reducing emissions, 2) poorest households are overcompensated on avg & 3) all revenue is returned, strongly limiting costs to each individual.
5/ 🛒 Price effects at €200/tCO2:
• Yoghurt & milk: +€0.25/kg
• Beef, sheep & goat meat: +€4/kg
4/ 📉 Emission reduction potential:
• At €30/tCO2, annual emissions fall by just 2 MtCO2eq.
• At the social cost of carbon (€200/tCO2), emissions drop by a significant 15 MtCO2eq.
3/ 💶 What is the effect of returning the public revenue as climate dividend? The poorest 20% of households are relieved by 0.14% of their income, i.e., on average they’d be overcompensated, while the better-off face an 0.02% reduction of their income
2/ 🍽️ We study how a climate fee on food combined with a #climatedividend could help achieve this target in a socially balanced way by encouraging households to choose less CO2-intensive foods—e.g., less red meat and dairy, more vegetables.
1/ 🐄🌾 Agriculture is responsible for 8% of Germany’s greenhouse gas emissions—about 62 MtCO2eq annually. The government aims to reduce this to 56 MtCO2eq by 2030.
New research on socially balanced policy for #sustainablediets! Why am I excited about the paper? It’s based on Julian’s Master’s thesis @freieuniversitaet.bsky.social @tuberlin.bsky.social, @pik-potsdam.bsky.social. I’m tremendously proud of this achievement! Here's a 🧵

(8/n) Higher GDP due to land taxes can be desirable, but this depends on the normative standpoint. Hence, we compare different welfare functions and show that already a very moderate level of inequality aversion is enough to make land rent taxes the best policy option.
(7/n) Our results suggest that land rent taxes reduce inequality, increase GDP and social welfare. Capital taxes are much less desirable and a tax on both types of wealth lies somewhere in the middle.
(6/n) How can this reduce inequality? With less capital tax & more land tax, 3 effects reduce inequality:
1) Housing prices fall (at least grow slower)
2) Increased investments -> higher GDP -> higher wages
3) More tax income for redistribution
(5/n) With capital taxes, by contrast, investors shift finance away from capital investments and instead demand for land increases, driving up land prices, but not land supply. The capital stock decreases and GDP falls.
(4/n) Under land rent taxes, investors redirect financial flows from land to capital investments. Importantly, while land supply is fixed, the capital stock grows, and output = GDP increases.
(3/n) Taxing land enhances investment in productive capital. This is the so-called (asset-)portfolio effect - a classic result by Martin Feldstein 1977. Now, we examine how governments can use this effect to reduce wealth inequality. So, how does the portfolio effect work?
(2/n) Importantly, wealth & capital aren’t equal. Often, it’s assumed that wealth consists of only one asset class: capital. In reality, there are more than that - and a very interesting one is land. So we analyze differences btw capital & land as tax base
#inequality is on the rise across #OECD nations, but at the same wealth taxes continually fell. In a new paper w/ Ottmar #Edenhofer, we present a new solution to reduce inequality: Tax land (and other rents). Why is this fair and also efficient? 🧵
