    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 ...

    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 ...

    Individual Differences in Short-term Social Dynamics: Theoretical Perspective and Empirical Development of the Social Dynamics Scale

    People have a need to form and maintain fulfilling social contact, yet they differ with respect to with whom they satisfy the need and how quickly this need is deprived or overly satiated. These social dynamics across relationships and across time are theoretically delineated in the current article. Furthermore, we developed a questionnaire to measure individual differences in three aspects of such ...

    Earn More Tomorrow: Overconfidence, Income Expectations, and Consumer Indebtedness

    This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt taking. We show suggestive evidence for a link between overconfidence and borrowing behavior in a representative survey of German households (German Socio-Economic Panel–Innovation Sample [GSOEP-IS]). This motivates a laboratory experiment to study causality behind these effects. In two experiments, ...

    Crowding of International Mutual Funds

    We study the relationship between crowding and performance in the active mutual fund industry. Using the equity holdings overlap of 17,364 global funds, we find that funds that crowd into the same stocks underperform passive benchmark funds by 1.4% per year. The negative returns to crowding can at least in part be explained by excess demand for liquidity and the associated discount for holding liquid ...

    Explaining the Absence of Climate Change Integration in Low-Carbon Sectoral Policies: An Analysis of Brazil’s Maritime Cabotage Policy

    Although maritime cabotage emits comparatively less CO2 per tonne kilometre than other means of transportation, the potential contribution of Brazil’s cabotage policy toward tackling climate change remained largely unexplored throughout its legislative process. Hence, to gather insights into how climate change can be integrated into sectoral policies, we apply Kingdon’s Multiple Streams Framework (MSF) ...

    Does Gender of Firm Ownership Matter? Female Entrepreneurs and the Gender Pay Gap

    We examine how the gender of business owners is related to the wages paid to female relative to male employees working in their firms. Using Finnish register data and employing firm fixed effects, we find that the gender pay gap is—starting from a gender pay gap of 11 to 12%—two to three percentage points lower for hourly wages in female-owned firms than in male-owned firms. Results are robust to how ...

    What is the Difference between Fossil Fuel Embargo and Price Shocks?

    In this paper, we model a fossil fuel embargo as a temporary quantity constraint on fossil fuel imports and wecompare the impact with the effect of a fossil fuel price shock. We show that while both shocks have similar responses of output and inflation, they differ with respect to the reaction of other macroeconomic components,such as consumption, exports and the trade balance. In particular, an embargo ...
