Abstract
The paper subjects seven structural DSGE models, all used heavily by policymaking institutions, to discretionary fiscal stimulus shocks using seven different fiscal instruments, and compares the results to those of two prominent academic DSGE models. There is considerable agreement across models on both the absolute and relative sizes of different types of fiscal multipliers. The size of many multipliers is large, particularly for spending and targeted transfers. Fiscal policy is most effective if it has moderate persistence and if monetary policy is accommodative. Permanently higher spending or deficits imply significantly lower initial multipliers.

Auswirkungen der aus dem Konjunkturpaket II für das Zentrale Innovationsprogramm Mittelstand (ZIM) bereitgestellten Mittel auf die konjunkturelle Entwicklung. Gutachten im Auftrag des Bundesministerium für Wirtschaft und Technologie (BMWi)

Abstract
Das Zentrale Innovationsprogramm Mittelstand (ZIM) des Bundesministeriums für Wirtschaft und Technologie unterstützt in Deutschland Forschung und Innovation in kleinen und mittleren Unternehmen. In Reaktion auf die weltweite Wirtschafts- und Finanzkrise wurde das ZIM in den Jahren 2009 und 2010 – zusätzlich zu dem Haushaltsvolumen von 626 Mio. Euro – um 900 Mio. Euro aus dem Konjunkturpaket II aufgestockt. Das Institut für Wirtschaftsforschung Halle (IWH) hat die konjunkturelle Hebelwirkung dieser Mittel quantifiziert. Ergebnis: Die staatliche Anschubfinanzierung in Höhe von 1,3 Mrd. Euro führte zu Forschungsprojekten der Unternehmen und Wissenschafts-einrichtungen in beinahe dreimal so hohem Umfang (3,7 Mrd. Euro). Über zuliefernde Firmen erhöht sich der volkswirtschaftliche Effekt nochmals um das Doppelte. Kumuliert über die Jahre 2009 bis 2011 werden bis zu 69 500 Arbeitsplätze gesichert oder neu geschaffen.

Regional Entrepreneurial Opportunities in the Biotech Industry: Exploring the Transition from Award-winning Nascent Entrepreneurs to Real Start-ups
H. Wolf, Claus Michelsen, Michael Schwartz
Abstract
Knowledge of factors that determine the transition from nascent entrepreneurship into real entrepreneurship is of major importance for policies aiming to effectively stimulate start-ups. Whereas scholars concentrated on person-specific factors to explain transition probabilities, environmental characteristics have been fairly neglected. Given that entrepreneurship is a strongly localized phenomenon, this paper argues that regional entrepreneurial opportunities are a driving force behind the transition from nascent entrepreneurship to new venture creation. Based on unique data on 103 nascent entrepreneurs in the German biotechnology industry, we empirically assess the importance of regional entrepreneurial opportunities on transition probabilities. Further, we introduce a new
approach to measure nascent entrepreneurship by capturing individuals that actively participate in start-up competitions and have won at least one competition. Controlling for technology and individual characteristics, we find strong support for our hypotheses relating to the significant impact of general regional opportunities, specific regional opportunities and the entrepreneurial environment for the probability of transition from award-winning nascent entrepreneurs to real start-ups.

Human Capital and Fertility in Germany after 1990: Evidence from a Multi-Spell Model

IWH Discussion Papers,
Nr. 22,
2009
Abstract
We analyze the timing of birth of the first three children based on German panel
data (GSOEP) within a hazard rate framework. A random effects estimator is
used to accommodate correlation across spells. We consider the role of human
capital – approximated by a Mincer-type regression – and its gender-specific
effects on postponement of parenthood and possible recuperation at higherorder
births. An advantage of the use of panel data in this context consists in
its prospective nature, so that determinants of fertility can be measured when
at risk rather than ex-post, thus helping to reduce the risk of reverse causality.
The analysis finds evidence for strong recuperation effects, i.e., women with
greater human capital endowments follow, on average, a different birth history
trajectory, but with negligible curtailment of completed fertility.

Evaluating the German (New Keynesian) Phillips Curve

IWH Discussion Papers,
Nr. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.
