Ampel-Monitor Energiewende: ambitionierte Ziele, aber zu geringe Dynamik

The German “traffic light” (Ampel) coalition has set ambitious new energy transition targets. Using an open data tool developed at DIW Berlin, we discuss the progress and challenges of selected indicators. Since the government took over, photovoltaic capacity increased by 45 % to 87 GW by April 2024, with a planned doubling by 2030. However, onshore wind power grew by only 11 % to 62 GW. The installation ...

DECIPHE – Demographic Change and the Intergenerational Persistence in Homeownership in Europe

DECIPHE ist das erste Projekt, das umfassend untersucht, ob und wie tiefgreifend sich demografische Veränderungen in Europa auf die intergenerationale Persistenz von Wohneigentum auswirken. Dabei werden Unterschiede zwischen Ländern, Regionen und Geburtskohorten berücksichtigt. Das Projekt nimmt  eine Lebensverlaufsperspektive auf Wohneigentum ein, bei der die Präferenzen und Ressourcen der...

DECIPHE – Demographic Change and the Intergenerational Persistence in Homeownership in Europe

DECIPHE is the first project to comprehensively study whether and how profound demographic changes in Europe impact the intergenerational persistence of homeownership, considering variations across countries, regions, and birth cohorts. It adopts a life course framework on housing tenure, in which individuals’ homeownership is shaped by their household members’ preferences and resources and...

Renewable Energy and Equilibrium Hedging in Electricity Forward Markets

We study the impact of renewable energy on forward markets for electricity. Previous literature shows that forward prices are determined by time-varying demand and volatile spot prices. We introduce supply risk from renewable generation and find that stochastic renewable output mitigates income risk for generating firms, in particular when negative shocks to renewable output have large positive price ...

Ergebnisse der EU-Wahl werden Europa schwächen und polarisieren

Technological Progress, Occupational Structure, and Gender Gaps in the German Labour Market

We analyze if technological progress and the change in the occupational structure have improved women’s position in the labour market. We show that women increasingly work in non-routine manual and in interactive occupations. However, the observed narrowing of the gender wage gap is entirely driven by declining gender wag gaps within, rather than between, occupations. A decomposition exercise reveals ...

Study on the Effectiveness of COVID-Aid on Firms

The study investigates the impact of COVID-related State aid measures (COVID-aid) on firms’ performance in selected EU countries, distinguishing among different categories of (pre-crisis) firm size, economic sector, and type of financial instrument received. The current analysis covers three countries with available National State Aid Registries, namely Italy, Poland, and Spain, which enable precise ...

Die neue Migrationspolitik kostet Milliarden und hilft nur minimal

Die Regierung kürzt immer stärker die Leistungen für Geflüchtete. Doch es ist ein Irrglaube, dass sich so Geld sparen lässt. Im Gegenteil: Es wird sogar teurer. Das Narrativ der Populisten, das auch zunehmend Politiker demokratischer Parteien befeuern, ist simpel: Geflüchtete erhielten zu großzügig Sozialleistungen vom deutschen Staat, was vielen Deutschen erheblich schade. So behauptete CDU-Chef Friedrich ...
