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.
Im Rahmen der Forschung zur sozial-ökologischen Transformation (SÖT) betrachten Forschende aus den verschiedenen Abteilungen des DIW Berlin die Risiken, Kosten und Nutzen dieser Transformation für private Haushalte, Unternehmen und staatliche Akteure in Deutschland und Europa. Aufbauend auf den bisherigen Schwerpunkten im Institut gehen die Forschenden des DIW Berlin insbesondere den ökonomischen und ...
A course by the Kiel Institute for the World Economy (IfW Kiel) In cooperation with DIW Berlin Researchers are often interested in calculating how variables respond over time to a given stimulus, such as a policy intervention. This is often referred to as an impulse response. The method of local projections offers a convenient approach to investigate such impulse response dynamics.

In ihrem Koalitionsvertrag hat die neue schwarz-rote Bundesregierung vereinbart, eine Rentenkommission einzusetzen, um die Zukunft des Alterssicherungssystems zu untersuchen. Zwar fehlen detaillierte Angaben zur Zusammensetzung und zum konkreten Auftrag der Kommission. ...
Noting that the shocks in vector autoregressive models can be correlated if a number of shocks is identified individually by multiple proxy variables, we propose a Generalized Method of Moments (GMM) approach for estimation that enforces uncorrelated shocks. We point out that if each proxy identifies exactly one shock and is uncorrelated with all other shocks, uncorrelatedness of the shocks provides ...
Public procurement accounts for a large share of Gross Domestic Product in many countries. Given its impact, governments and other public authorities can leverage their purchasing decisions to pursue welfare goals; among these, environmental protection and climate change mitigation have particular priority. By using procurement practices that account for the environmental quality of bids – so-called ...
Introducing electricity purchase conditions in renewable fuel regulations and carbon accounting is a controversial issue in the US and Europe. We argue that their impact must be assessed considering demand flexibility, local grid conditions, and overlapping policy instruments such as emissions trading schemes and renewable portfolio standards. The introduction of more stringent requirements has a significant ...
