Studies of the crude oil market based on structural vector autoregressive (VAR) models typically assume a time-invariant model and transmission of shocks or they consider a time-varying model and shock transmission. We assume a heteroskedastic reduced-form VAR model with time-invariant slope coefficients and test for time-varying impulse responses in a model for the global crude oil market that includes ...
The project seeks to identify the share of productive and fast-growing firms in the economy, their characteristics such as sector, location (urban/rural, low-density, high-density, etc.), size and age since formation, and their growth performance. Furthermore, it will be analyzed - as far as the data situation allows - which factors contribute to the success.
Das Projekt zielt darauf ab, den Anteil von produktiven und schnell wachsenden Unternehmen an der Wirtschaft, ihre Merkmale wie Sektor, Standort (Stadt/Land, schwach verdichtet, verdichtet, stark verdichtet etc.), Größe und Alter seit der Gründung sowie ihre Wachstumsentwicklung zu ermitteln. Ferner soll untersucht werden - soweit es die Datenlage zulässt - welche Einflussgröße zum Erfolg beitragen.
The study will provide a quantitative and qualitative assessment of the impact of the State aid rules for banks, which will serve as evidence for the evaluation of the State aid rules applicable to banks in difficulty since their entry into force in end-2008.
The main purpose of the project is to put together a comprehensive database including qualitative and quantitative information from past merger cases, which would enable DG Competition to produce statistical reports which could serve as an input to DG Competition's decision making practice in relation to EU merger control, both for operational and for policy purposes.
To determine how wives’ and husbands’ retirement options affect their spouses’ (and their own) labour supply decisions, we exploit (early) retirement cutoffs by way of a regression discontinuity design. Several German pension reforms since the early 1990s have gradually raised women’s retirement age from 60 to 65, but also increased ages for several early retirement pathways affecting both sexes. We ...
