Abstract
Technological progress builds upon itself, with the expansion of invention in one domain propelling future work in linked fields. Our analysis uses 1.8 million US patents and their citation properties to map the innovation network and its strength. Past innovation network structures are calculated using citation patterns across technology classes during 1975–1994. The interaction of this preexisting network structure with patent growth in upstream technology fields has strong predictive power on future innovation after 1995. This pattern is consistent with the idea that when there is more past upstream innovation for a particular technology class to build on, then that technology class innovates more.

Joint Economic Forecast: German Economy on Track – Economic Policy needs to be Realigned
Thanks to a stable job market and solid consumption, the German economy is experiencing a moderate upswing. The GDP is expected to increase by 1.9 percent this year, 1.4 percent in 2017, and 1.6 percent in 2018, according to the Gemeinschaftsdiagnose (GD, joint economic forecast) that was prepared by five of Europe’s leading economic research institutes on behalf of the Federal Government. The most recent GD, which was released in April, predicted a GDP growth rate of 1.6 percent for 2016 and 1.5 percent for 2017.

Strong Financial Literacy could Lead to More Self-employment
The probability that a person is self-employed also depends on how much financial literacy they have. A new study by the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association recently confirmed this correlation.

Plant-level Employment Development before Collective Displacements: Comparing Mass Layoffs, Plant Closures, and Bankruptcies
Daniel Fackler, Steffen Müller, Jens Stegmaier
Abstract
To assess to what extent collective job displacements can be regarded as unanticipated exogenous shocks for affected employees, we analyze plant-level employment patterns before bankruptcy, plant closure without bankruptcy, and mass layoff. Utilizing administrative data covering all West German private sector plants, we find no systematic employment reductions prior to mass layoffs, a strong and long-lasting reduction prior to closures, and a much shorter shadow of death preceding bankruptcy. Our analysis of worker flows underlines that bankruptcies seem to struggle for survival while closures follow a shrinking strategy. We conclude that the scope of worker anticipation of upcoming job loss is smallest for mass layoffs and largest for closures without bankruptcy.

How Selective Are Real Wage Cuts? A Micro-analysis Using Linked Employer–Employee Data
Boris Hirsch, Thomas Zwick
LABOUR: Review of Labour Economics and Industrial Relations,
No. 4,
2015
Abstract
Using linked employer–employee panel data for Germany, we investigate whether firms implement real wage reductions in a selective manner. In line with insider–outsider and several strands of efficiency wage theory, we find strong evidence for selective wage cuts with high-productivity workers being spared even when controlling for permanent differences in firms' wage policies. In contrast to some recent contributions stressing fairness considerations, we also find that wage cuts increase wage dispersion among peers rather than narrowing it. Notably, the same selectivity pattern shows up when restricting our analysis to firms covered by collective agreements or having a works council.

Does the Plant Size–wage Differential Increase with Tenure? Affirming Evidence from German Panel Data
Daniel Fackler, Thorsten Schank, Claus Schnabel
Economics Letters,
2015
Abstract
We show that the major part of the plant size–wage premium in Germany is reflected in different wage growth patterns in plants of different size. This is consistent with the hypothesis that large firms ‘produce’ more skilled workers over time.

Works Councils and Labour Productivity: Looking beyond the Mean
Steffen Müller
British Journal of Industrial Relations,
No. 2,
2015
Abstract
After more than 25 years of empirical investigation, the analysis of works council effects on establishment productivity is still an active field of economic research. I present first evidence for works council regression coefficients along the unconditional log labour productivity distribution in Germany. The highest (lowest) coefficients were found at the bottom (top) of the distribution, which suggests that works councils have the most beneficial effects at low levels of productivity. Importantly, coefficients are positive at each productivity level. The results shed light on a classical theoretical argument concerning moderating factors for the productivity effect of employee participation.

The Levelling Effect of Product Market Competition on Gender Wage Discrimination
Boris Hirsch, Michael Oberfichtner, Claus Schnabel
IZA Journal of Labor Economics,
No. 19,
2014
Abstract
Using linked employer–employee panel data for West Germany that include direct information on the competition faced by plants, we investigate the effect of product market competition on the gender pay gap. Controlling for match fixed effects, we find that intensified competition significantly lowers the unexplained gap in plants with neither collective agreements nor a works council. Conversely, there is no effect in plants with these types of worker codetermination, which are unlikely to have enough discretion to adjust wages in the short run. We also document a larger competition effect in plants with few females in their workforces. Our findings are in line with Beckerian taste-based employer wage discrimination that is limited by competitive forces.

Firm Leadership and the Gender Pay Gap: Do Active Owners Discriminate more than Hired Managers?
Boris Hirsch, Steffen Müller
Journal for Labour Market Research,
No. 1,
2014
Abstract
Using a large linked employer–employee data set for Germany, we investigate differences in the unexplained gender pay gap between owner-run and manager-run firms. We hypothesise that owner-managers and hired managers differ in their discretion to engage in profit-reducing taste discrimination against women, which would translate into different pay gaps depending on leadership regime. We find that unexplained gaps are significantly higher in owner-run firms, both statistically and economically. Yet, scrutinising these results by restricting our analysis to firms that only differ in leadership regime, this substantial difference disappears. Therefore, our findings do not support that active owners are more discriminatory per se.

The Impact of Female Managers on the Gender Pay Gap: Evidence from Linked Employer–Employee Data for Germany
Boris Hirsch
Economics Letters,
No. 3,
2013
Abstract
We find that increasing the female share in first-level management by 10% points decreases the unexplained within-job gender pay gap by 0.5 log points. The effect is more pronounced for the female share in second-level than in first-level management.
