German Economy: Strong domestic demand compensates for weak exports
The upturn of the German economy is expected to gain further momentum as a consequence of strong domestic demand. Real gross domestic product is expected to increase by 1.6% in 2016. Consumer prices are expected to rise by 0.9%. Unemployment is expected to rise slightly because it will take time to integrate refugees into the labour market.

Young, Restless and Creative: Openness to Disruption and Creative Innovations
Daron Acemoglu, Ufuk Akcigit, Murat Alp Celik
NBER Working Paper,
No. 19894,
2015
Abstract
This paper argues that openness to new, unconventional and disruptive ideas has a first-order impact on creative innovations—innovations that break new ground in terms of knowledge creation. After presenting a motivating model focusing on the choice between incremental and radical innovation, and on how managers of different ages and human capital are sorted across different firms with different degrees of openness to disruption, we provide firm-level, patent level and cross-country evidence consistent with this pattern. Our measures of creative innovations proxy for innovation quality (average number of citations per patent) and creativity (fraction of superstar innovators, the likelihood of a very high number of citations, and generality of patents). Our main proxy for openness to disruption is the age of the manager - based on the idea that only companies or societies open to such disruption will allow the young to rise up within the hierarchy. Using this proxy at the firm, patent and country level, we present robust evidence that openness to disruption is associated with more creative innovations, but we also show that once the effect of the sorting of young managers to firms that are more open to disruption is factored in, the (causal) impact of manager age on creative innovations is small.

Does Going Public Affect Innovation?
Shai B. Bernstein
Journal of Finance,
No. 4,
2015
Abstract
This paper investigates the effects of going public on innovation by comparing the innovation activity of firms that go public with firms that withdraw their initial public offering (IPO) filing and remain private. NASDAQ fluctuations during the book-building phase are used as an instrument for IPO completion. Using patent-based metrics, I find that the quality of internal innovation declines following the IPO, and firms experience both an exodus of skilled inventors and a decline in the productivity of the remaining inventors. However, public firms attract new human capital and acquire external innovation. The analysis reveals that going public changes firms' strategies in pursuing innovation.

Ökonomisches Wachstum in Ostdeutschland seit der Wiedervereinigung: Eine empirische Perspektive
Maike Irrek
Hochschulschrift, Online-Publikation,
2015
Abstract
The sluggish convergence between East and West Germany and the persistent productivity deficit of the East Germany economy are the motivation of a large number of studies and analyses. Public physical capital and human capital play a major role therein. However, there are no appropriate time series to verify the hypotheses which are discussed in the literature in empirical studies. Therefore, in this thesis public and private physical capital as well as human capital will be estimated for East and West Germany. The newly constructed data are then used to derive more exact estimates of total factor productivity in both regions.

Returns to Skills around the World: Evidence from PIAAC
Eric A. Hanushek, Guido Schwerdt, Simon Wiederhold, Ludger Woessmann
European Economic Review,
January
2015
Abstract
Existing estimates of the labor-market returns to human capital give a distorted picture of the role of skills across different economies. International comparisons of earnings analyses rely almost exclusively on school attainment measures of human capital, and evidence incorporating direct measures of cognitive skills is mostly restricted to early-career workers in the United States. Analysis of the new PIAAC survey of adult skills over the full lifecycle in 23 countries shows that the focus on early-career earnings leads to underestimating the lifetime returns to skills by about one quarter. On average, a one-standard-deviation increase in numeracy skills is associated with an 18 percent wage increase among prime-age workers. But this masks considerable heterogeneity across countries. Eight countries, including all Nordic countries, have returns between 12 and 15 percent, while six are above 21 percent with the largest return being 28 percent in the United States. Estimates are remarkably robust to different earnings and skill measures, additional controls, and various subgroups. Instrumental-variable models that use skill variation stemming from school attainment, parental education, or compulsory-schooling laws provide even higher estimates. Intriguingly, returns to skills are systematically lower in countries with higher union density, stricter employment protection, and larger public-sector shares.

Coordination between Municipalities and Local Non-Municipal Public Units (NMPUs) for Supporting Urban Economic Development: Theoretical Analysis and Empirical Evidence for the Example of Universities in Germany
Martin T. W. Rosenfeld, J. Hinz
Koordination raumwirksamer Politik: Mehr Effizienz und Wirksamkeit von Politik durch abgestimmte Arbeitsteilung,
2015
Abstract
In many European cities, policymakers are trying to change the local paths of economic development to head in new directions, e.g. by trying to become a location for Non-Municipal Public Units (NMPUs), like federal special agencies, state museums, military bases, universities or publicly funded research institutes. But as the competencies for such local NMPUs are allocated to higher levels of government, the municipal level has no direct formal institutional responsibilities for influencing their location. Once a NMPU has chosen a certain location, support from the municipality may, however, stabilize the NMPU. There are some categories of NMPUs that should have considerable interest in local conditions, as determined by the municipal level. This paper first theoretically categorizes NMPUs with regard to their importance for the urban economy, with regard to the importance of local conditions for the performance of NMPUs and with regard to their degree of fiscal autonomy. It is shown that universities are one example of NMPUs where the relevance of coordinating activities with the municipalities is fairly high. The benefits of universities for local economic development have often been discussed. From the point of view of universities, their capacity to attract human capital depends on factors which may be influenced by the municipalities. This means that there is a reciprocal relationship between municipalities and universities; coordination by cooperation between the partners could be useful for both – but in practice there is often a lack of cooperation. Information policy is one relevant field for coordination: the city should highlight publicly the advantages of local universities; the universities should highlight the advantages of their city. As information policy is a field for which empirical data is available, the empirical part of the paper presents results from an analysis based on the internet presentations of selected cities and universities. It is shown that in most cities the level of coordination in this field is so far quite low. One possible way to achieve a higher degree of coordination could be to introduce fiscal incentives for cities.

Kommentar: Betriebsgrößenstruktur und Arbeitsmarktergebnisse
Steffen Müller
Wirtschaft im Wandel,
No. 5,
2014
Abstract
Trotz aller Fortschritte bei der wirtschaftlichen Angleichung Ost- und Westdeutschlands seit der Vereinigung wird in der öffentlichen Debatte häufig auf fortbestehende Unterschiede bei Löhnen und Arbeitsproduktivität verwiesen. Als Erklärung hierfür wird der vergleichsweise geringe Anteil großer und damit in der Regel auch produktiverer und besser zahlender Betriebe in Ostdeutschland angeführt. Die Größe eines Betriebes ist jedoch – von möglichen Skalenerträgen einmal abgesehen – für sich genommen kein Bestimmungsfaktor für ökonomische Prosperität. Für das Verständnis der Folgen einer kleinteilig organisierten Wirtschaft muss geklärt werden, über welche Mechanismen die Betriebsgrößenstruktur auf Löhne und Arbeitsproduktivität wirkt.

Do Better Pre-migration Skills Accelerate Immigrants' Wage Assimilation?
Boris Hirsch, Elke J. Jahn, Ott Toomet, Daniela Hochfellner
Labour Economics,
2014
Abstract
This paper analyzes wage assimilation of ethnic German immigrants to Germany using unique administrative data that include an administrative estimate of immigrants' expected wage in Germany at the time of migration. We find that a 10% higher wage potential translates into a 1.6% higher wage in Germany when also controlling for educational attainment, thus pointing at partial transferability of pre-migration skills to the host country's labor market. We also document that wage assimilation is significantly accelerated for immigrants with higher wage potentials. Our results are both in line with complementarities between pre-migration skills and host country-specific human capital and a U-shaped pattern of immigrants' job mobility with initial downgrading and subsequent upgrading.

Socially Gainful Gender Quotas
Walter Hyll, Oded Stark
Journal of Economic Behavior and Organization,
No. 105,
2014
Abstract
We study the impact of gender quotas on the acquisition of human capital. We assume that individuals’ formation of human capital is influenced by the prospect of landing high-pay top positions, and that these positions are regulated by gender-specific quotas. In the absence of quotas, women consider their chances of getting top positions to be lower than men’s. The lure of top positions induces even men of relatively low ability to engage in human capital formation, whereas women of relatively high ability do not expect to get top positions and do not therefore engage in human capital formation. Gender quotas discourage men who are less efficient in forming human capital, and encourage women who are more efficient in forming human capital. We provide a condition under which the net result of the institution of gender quotas is an increase in human capital in the economy as a whole.
