Was taugt der Investitionsbooster?Reint GroppDer Spiegel, 23. Juni 2025
Climate change and inequality are critical and interrelated defining issues for this century. Despite growing empirical evidence on the economic incidence of climate policies and impacts, mainstream model-based assessments are often silent on the interplay between climate change and economic inequality. For example, all the major model comparisons reviewed in IPCC neglect within-country inequalities. Here we fill this gap by presenting a model ensemble of eight large-scale Integrated Assessment Models belonging to different model paradigms and featuring economic heterogeneity. We study the distributional implications of Paris-aligned climate target of 1.5 degree and include different carbon revenue redistribution schemes. Moreover, we account for the economic inequalities resulting from residual and avoided climate impacts. We find that price-based climate policies without compensatory measures increase economic inequality in most countries and across models. However, revenue redistribution through equal per-capita transfers can offset this effect, leading to on average decrease in the Gini index by almost two points. When climate benefits are included, inequality is further reduced, but only in the long term. Around mid-century, the combination of dried-up carbon revenues and yet limited climate benefits leads to higher inequality under the Paris target than in the Reference scenario, indicating the need for further policy measures in the medium term.
This study investigates whether and how financial technologies (FinTech) influence the effectiveness of monetary policy transmission. We use an interacted panel vector autoregression model to explore how the effects of monetary policy shocks change with regional-level FinTech adoption. Results indicate that FinTech adoption generally mitigates the transmission of monetary policy to real GDP, consumer prices, bank loans, and housing prices, with the most significant impact observed in the weakened transmission to bank loan growth. The relaxed financial constraints, regulatory arbitrage, and intensified competition are the possible mechanisms underlying the mitigated transmission.
Amiti et al. (2024) seek to answer a very topical and important research question: How much did supply-side disruptions and the tight labor market contribute to the recent surge in inflation? The answer provided by the authors is: about 2 percentage points. To arrive at their answer, the authors use a calibrated two-sector New Keynesian model in which they use three correlated shocks in a perfect-storm type setting. The paper also has an interesting empirical part that provides evidence that the channels emphasized in the theoretical model are at work in the data.
*** „Inflationsausgleichszahlung“ und Tariflohnsteigerungen dürften Verbraucherpreis-inflation nur knapp ausgleichen. *** Die Tarifvertragsparteien des öffentlichen Dienstes der Länder haben sich vor kurzem auf einen neuen Tariflohnabschluss geeinigt: Es wurde vereinbart, dass Einmalzahlungen von insgesamt 3 000 Euro in elf Monatsbeträgen abgabenfrei als so genannte Inflationsausgleichsprämie gezahlt werden. Bereits im Dezember 2023 soll ein Teilbetrag in Höhe von 1 800 Euro ausgezahlt werden, von Januar bis einschließlich Oktober gibt es monatlich jeweils 120 Euro. Die regulären Tabellenentgelte erhöhen sich währenddessen nicht. Erst ab November 2024, wenn die Inflationsausgleichszahlung wegfällt, gibt es eine Stufenerhöhung über 200 Euro für alle Beschäftigten. Auf diese setzt ab Februar 2025 dann eine reguläre prozentuale Erhöhung von 5,5% auf. Der Tarifvertrag läuft bis Ende Oktober 2025.
