Long-term effects of privatisation in eastern Germany: award-winning US economist begins large-scale research project at the IWH
It is one of the most prestigious awards in the German scientific community: the Max Planck-Humboldt Research Award 2019 endowed with €1.5 million goes to Ufuk Akcigit, Professor of Economics at the University of Chicago. At the Halle Institute for Economic Research (IWH), Akcigit aims to use innovative methods to investigate why the economy in eastern Germany is still lagging behind that in western Germany – and what role the privatisation process 30 years ago played in this.

Uwe Cantner, Eva Dettmann, Alexander Giebler, Jutta Günther, Maria Kristalova
Regional Studies,
No. 9,
2019
Abstract
Public innovation subsidies in a regional environment are expected to unfold a positive economic impact over time. The focus of this paper is on an assessment of the long-run impact of innovation and innovation subsidies in German regions. This is scrutinized by an estimation approach combining panel model and time-series characteristics and using regional data for the years 1980–2014. The results show that innovation and innovation subsidies in the long run have a positive impact on the economic development of regions in Germany. This supports a long-term strategy for regional and innovation policy.

Downturn in Germany continues
Trade disputes are causing international trade in goods to decline this year. The manufacturing industry in Germany is particularly affected by this. However, a robust labour market is supporting the economy. According to IWH autumn economic forecast, German gross domestic product (GDP) will increase by 0.5% in 2019. At 1%, output growth in East Germany is likely to be significantly higher than in West Germany.

The Internet Effects on Sex Crime Offenses – Evidence from the Broadband Internet Expansion in Germany
André Diegmann
Journal of Economic Behavior and Organization,
September
2019
Abstract
This paper studies the effects of the introduction of a new mass medium on sex crime in Germany. I use unique data on criminal offenses and broadband internet measured at the municipal level to shed light on this issue. In order to address endogeneity in broadband internet availability, I exploit technical peculiarities at the regional level that determine the roll-out of high-speed internet. Results provide evidence of a substitution effect of internet exposure on sex crime. The substitution effect is neither driven by differences in reporting behavior, nor by matching processes at the victim and offender side. This suggests that the consumption of extreme media plays an important role in explaining the documented high-speed internet effect.

IWH Flash Indicator,
No. 3,
2019
Abstract
Die deutsche Wirtschaft schrumpfte im zweiten Quartal 2019 um 0,1%, nachdem das Bruttoinlandsprodukt zu Jahresbeginn noch um 0,4% zugelegt hatte. Der aktuelle IWH-Flash-Indikator deutet darauf hin, dass die Konjunktur auch in den kommenden beiden Quartalen schwach bleiben wird. So dürfte die Wirtschaft im dritten Quartal 2019 stagnieren, für das vierte Quartal kann ein kleines Plus von 0,2% erwartet werden.

Power Generation and Structural Change: Quantifying Economic Effects of the Coal Phase-out in Germany
Christoph Schult, Katja Heinisch, Oliver Holtemöller
Abstract
In the fight against global warming, the reduction of greenhouse gas emissions is a major objective. In particular, a decrease in electricity generation by coal could contribute to reducing CO2 emissions. We study potential economic consequences of a coal phase-out in Germany, using a multi-region dynamic general equilibrium model. Four regional phase-out scenarios before the end of 2040 are simulated. We find that the worst case phase-out scenario would lead to an increase in the aggregate unemployment rate by about 0.13 [0.09 minimum; 0.18 maximum] percentage points from 2020 to 2040. The effect on regional unemployment rates varies between 0.18 [0.13; 0.22] and 1.07 [1.00; 1.13] percentage points in the lignite regions. A faster coal phase-out can lead to a faster recovery. The coal phase-out leads to migration from German lignite regions to German non-lignite regions and reduces the labour force in the lignite regions by 10,100 [6,300; 12,300] people by 2040. A coal phase-out until 2035 is not worse in terms of welfare, consumption and employment compared to a coal-exit until 2040

East Germany Three Decades After the Wall Came Down: What has Been Achieved and What Should Economic Policy Do?
Reint E. Gropp, Gerhard Heimpold
Wirtschaftsdienst,
No. 7,
2019
Abstract
The persistent difference in productivity between East and West Germany not only results from the relative absence of large firms based in the East as many believe. Companies of all sizes exhibit an East-West productivity gap. The gap is larger in urban regions. Scarcity of skilled labour has emerged as the new barrier to business development. In order to boost productivity, economic policy should avoid additional subsidies that are conditional on creating jobs. Additionally, the potential of East German urban areas should be better explored. Mitigating the shortage in qualified workers requires in-migration of skilled labour from abroad, supported by an open mindset and environment.

HIP, RIP, and the Robustness of Empirical Earnings Processes
Florian Hoffmann
Quantitative Economics,
No. 3,
2019
Abstract
The dispersion of individual returns to experience, often referred to as heterogeneity of income profiles (HIP), is a key parameter in empirical human capital models, in studies of life‐cycle income inequality, and in heterogeneous agent models of life‐cycle labor market dynamics. It is commonly estimated from age variation in the covariance structure of earnings. In this study, I show that this approach is invalid and tends to deliver estimates of HIP that are biased upward. The reason is that any age variation in covariance structures can be rationalized by age‐dependent heteroscedasticity in the distribution of earnings shocks. Once one models such age effects flexibly the remaining identifying variation for HIP is the shape of the tails of lag profiles. Credible estimation of HIP thus imposes strong demands on the data since one requires many earnings observations per individual and a low rate of sample attrition. To investigate empirically whether the bias in estimates of HIP from omitting age effects is quantitatively important, I thus rely on administrative data from Germany on quarterly earnings that follow workers from labor market entry until 27 years into their career. To strengthen external validity, I focus my analysis on an education group that displays a covariance structure with qualitatively similar properties like its North American counterpart. I find that a HIP model with age effects in transitory, persistent and permanent shocks fits the covariance structure almost perfectly and delivers small and insignificant estimates for the HIP component. In sharp contrast, once I estimate a standard HIP model without age‐effects the estimated slope heterogeneity increases by a factor of thirteen and becomes highly significant, with a dramatic deterioration of model fit. I reach the same conclusions from estimating the two models on a different covariance structure and from conducting a Monte Carlo analysis, suggesting that my quantitative results are not an artifact of one particular sample.

Abstract
The present study examines the socio-economic consequences of a climate policy-driven coal phase-out in Germany. A focus lies on the lignite industry – especially in the lignite regions. In a first step, the regions are spatially defined and described. Additional analysis is based on energy economic modelling. The model examines phase-out scenarios, which differ in the chosen criteria for the order of power plant closure (specific emissions or plant age). An input-output-model and a regional macroeconomic model build up on these phase-out pathways and examine the socio economic effects of the phase-out in the lignite regions as well as in the rest of Germany. The combination of both models offers the advantage to consider the phase-out from different perspective and hence derive different and more robust effects. The models show, on the one hand, that in an early phase-out the negative effects of structural change are visible earlier. On the other hand, recuperative effects can counteract the negative consequences according to the regional economic model.
Furthermore, the structural change creates economic opportunities. Those opportunities are primarily diversified economic activities. Case studies show significant employment potentials for the lignite regions. New jobs in renewable energies and energetic optimization of buildings can already counteract the negative employment effects associated with the investigated structural change. The study concludes, describing accompanying political instruments that can support the regions on their way to master the challenges of the up-coming structural change.
