Selbst ohne die Kindergrundsicherung kann der Staat Milliarden für arme Kinder mobilisieren – ohne mehr Geld auszugeben. Dafür müsste er nur an gewisse Freibeträge ran. Mit großen Ambitionen war die Bundesregierung angetreten, um Kinderarmut durch die Einführung einer Kindergrundsicherung zu bekämpfen. Diese Kindergrundsicherung steht jedoch nun vor dem Scheitern, auch weil es vielen nicht um den Inhalt ...
This paper investigates how the number of brackets and the choice of upper cutoffs in grouped data affect the metric approximation of income and wealth. The literature currently lacks a definition of what should be considered too few brackets or too-low cut-offs. Using German survey data, we show that more than six (eight) brackets and an upper cut-off at the 95th (97th) percentile are sufficient to ...
Evidence on how proximity to ethnic outgroups shapes attitudes toward immigration remains inconclusive. We suggest this may be driven, in part, by the fact that studies rarely account for the role of residential segregation. We argue that how the minority-share in an environment affects majority-group attitudes will depend on how segregated groups are from one another. To explore this, we undertake ...
Significant amounts of electricity consumed in air and water pumping make wastewater treatment energy-intensive. This study investigates the potential power system benefits of load shifting within these pumping processes. As a case study, the Irish power system and wastewater sector are studied by using an integrated modelling approach. The results show that demand flexibility within the wastewater ...
Ökonom Marcel Fratzscher zeigt sich schockiert über unlautere Wahlversprechen. Milliardenschwere Steuerentlastungen hält er für unrealistisch. Was ihm in der aktuellen Lage trotzdem Hoffnung macht.

Gibt es etwas, das Ihnen als Ökonom Hoffnung ...
This study examines how student aid eligibility influences application decisions to higher education using administrative data from France. We study the impact of a change in income thresholds for aid eligibility. We find that aid eligibility did not have a uniform effect on students’ applications but varied by gender and academic performance. Highperforming male students shifted their First-Ranked ...
Common ownership - where several firms are (partially) owned by the same investors - and its impact on product market competition has recently drawn much attention. This paper focuses on its implications for market entry. We consider the entry decisions of generic pharmaceutical firms into drug markets that are opened up by the end of regulatory protection and which were previously dominated by a single ...
Der Schweinezyklus beschreibt das Problem der Zeitverzögerung bei der Anpassung des Angebots auf einem Markt. Der Begriff geht auf den früheren DIW-Ökonomen Arthur Hanau (1902-1985) und dessen Dissertation „Die Prognose der Schweinepreise“ zurück, die er im Jahr 1928 im Vierteljahrsheft zur Konjunkturforschung veröffentlichte – damals hieß das DIW Berlin noch Institut für Konjunkturforschung.
