Så meget koster det ekstreme sommervejr for os europæere - og det bliver kun værre I år er regningen for sommerens hedebølger, tørke og oversvømmelser mindst 320 milliarder kroner, men om få år er prisen oppe på en billion kroner.

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...

Is Recycling Wasted? Circular Economy and the Material Rebound Effect We investigate how circular economy policies-such as increased recycling or reduced waste generation-affect primary (virgin) natural resource use at the macro l

🚨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

Redirecting

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

Ny københavnsk klimaplan hegles ned af økonomer: ”Minimal CO2-reduktion for et astronomisk højt beløb” : Klima - Altinget | Nyheder, analyser og debat om dansk politik Første udkast til Københavns nye klimaplan byder på milliarddyre investeringer. Men klimaeffekten er tvivlsom og virkemidlerne usikre, lyder det fra økonomer. For nemt at sidde i et elfenbenstårn og s...

@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

Økonomer: Salg af CO2-kvoter til at finansiere grøn trepart bryder med central prioritet Salg af fire millioner CO2-kvoter til at finansiere treparten virker inkonsistent med det hidtidige fokus på lækage i klimapolitikken. Politikerne bør anerkende den sandsynlige lækageeffekt fremfor at...

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

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

(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

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

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

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

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

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
