Hvor meget koster det ekstreme sommervejr europæerne?

Jeg kommenterer idag på et nyt studie, der undersøger netop det.

Og regningen bliver nok kun større i fremtiden...

🚨Working Paper Alert

We ask: can circular economy policies backfire?

In a macroeconomic model, we show that circular economy policies (e.g., increased recycling) may backfire in the sense that they increase virgin natural resource use

Publication alert! 🚨

10 years in the making!

Main takeaways:
💡 A stricter environmental policy unambiguously reduces economic growth
💡 But the effect is highly non-linear
💡 Economic growth barely affected by realistic environmental policy changes

@mogensfosgerau.bsky.social og jeg kommenterer i dag på et udkast til Københavns Kommunes klimaplan

Det bliver nogle dyre CO2e-reduktioner

Vi kunne have fået meget mere klima for de penge

Men konsulenterne har haft en fest med at beregne KK's klimaaftryk

Den Grønne Trepart finansieres delvist ved at sælge 4 mio. CO2-kvoter, som skulle være annulleret

Politikkerne er nødt til at anerkende, at det kommer med en omkostning for klimaet på ca. 4 mio. ton CO2

Our numerical simulations show that our tax-subsidy scheme could provide a welfare gain of around 0.3 percent of national income if politicians have a strong aversion to carbon leakage

End of 🧵

12/N

While the uniform carbon tax ensures a domestic emission reduction target, the other instruments depend on the politicians’ aversion to leakage

With no aversion to leakage, only a uniform carbon tax is needed

11/N

(7) Tax on domestic production of fossil fuels

Intuition: reducing domestic production increases net imports, thereby increasing the international price of fossil fuels and thereby decreasing foreign consumption

10/N

(6) Subsidy to green energy production

Intuition: increasing domestic production reduces net imports, thereby reducing the international price of green energy and thereby increasing foreign consumption, resulting in lower fossil fuel use

9/N

(5) Tax on green energy consumption

Intuition: increasing domestic production reduces net imports, thereby reducing the international price of green energy and thereby increasing foreign consumption, resulting in lower fossil fuel use

8/N

(4) Consumption taxes on all non-energy goods

Intuition: reduction in domestic consumption reduces net imports, thereby reducing the international price of green energy and thereby increasing foreign consumption, resulting in lower fossil fuel use

7/N

(3) Location subsidies to all non-energy sectors

Intuition: counteract leakage at the extensive intensive margin by reducing the profit loss from regulation

6/N

(2) Output subsidies to all non-energy sectors

Intuition: counteract leakage at the intensive margin by increasing international competitiveness

5/N

(1) A uniform carbon tax on households and all non-energy sectors

Intuition: equalize marginal abatement costs across sectors and ensures a domestic emissions target

4/N

Our general equilibrium model prescribes an intuitive tax-subsidy scheme with 7 elements…

3/N

As a novel feature, we distinguish between leakage at the extensive margin, where domestic firms relocate to foreign countries, and leakage at the intensive margin, where domestic firms lose world market shares

2/N

Excited to share this open access article, forthcoming in The Scandinavian Journal of Economics @scandjecon.bsky.social

We design a cost-effective tax-subsidy scheme that reduces domestic carbon emissions while also addressing leakage

*without* Border Carbon Adjustments

Det er svært at se, at Energiø Bornholm giver samfundsøkonomisk mening - selv hvis man medregne forsyningssikkerhed

Det har jeg kommenteret på til @klimamonitor.bsky.social

Jeg vil igen opfordre til, at man trækker stikket på Energiø Bornholm
