Abstract
Die vorliegende Expertise verfolgte das Ziel, Datenbedarfe für die Evaluierung der Kapitel-1-Maßnahmen des InvKG abzuleiten. Die Evaluierung und die daraus entstehenden Datenbedarfe müssen sich in ein theoretisches Modell der ökonomischen Literatur zur Wirkung von Politikmaßnahmen einordnen lassen. Bei den Kapitel-1-Maßnahmen handelt es sich im weitesten Sinne um Investitionen in wirtschaftsnahe Infrastrukturen. Charakteristisch für Infrastrukturen ist, dass sie durch mittlere Zeiträume der Planung und Errichtung auf der einen sowie lange Nutzungszeiträume auf der anderen Seite gekennzeichnet sind. Hinzu kommt, dass die Phasen der Planung/Errichtung und der Nutzung Aspekte von Marktmängeln berühren. In der Praxis unterliegt dieser Bereich daher einer umfassenden staatlichen Regulierung.

Abstract
Small and young businesses are essential for job creation, innovation, and economic growth. Even most of the superstar firms start their business life small and then grow over time. Small firms have less internal resources, which makes them more fragile and sensitive to macroeconomic conditions. This suggests the need for frequent and real-time monitoring of the small business sector’s health. Previously this was difficult due to a lack of appropriate data. This paper fills this important gap by developing a new Intuit QuickBooks Small Business Index that focuses on the smallest of small businesses with at most 9 workers in the US and the UK and at most 19 workers in Canada. The Index aggregates a sample of anonymous Quick- Books Online Payroll subscriber data (QBO Payroll sample) from 333,000 businesses in the US, 66,000 in Canada, and 25,000 in the UK. After comparing the QBO Payroll sample data to the official statistics, we remove the seasonal components and use a Flexible Least Squares method to calibrate the QBO Payroll sample data against official statistics. Finally, we use the estimated model and the QBO Payroll sample data to generate a near real-time index of economic activity. We show that the estimated model performs well both in-sample and out-of-sample. Additionally, we use this analysis for different regions and industries. Keywords:

Study on Europe's top bankers: Risky business despite bonus cap
Ten years ago, the EU Parliament decided to cap the flexible remuneration of bank managers. But the cap on bonuses misses its target: Managers of systemically important European banks take high risks without changes, shows a study by the Halle Institute for Economic Research (IWH).
