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.

Structural Interpretation of Vector Autoregressions with Incomplete Identification: Revisiting the Role of Oil Supply and Demand Shocks
Christiane Baumeister, James D. Hamilton
American Economic Review,
No. 5,
2019
Abstract
Traditional approaches to structural vector autoregressions (VARs) can be viewed as special cases of Bayesian inference arising from very strong prior beliefs. These methods can be generalized with a less restrictive formulation that incorporates uncertainty about the identifying assumptions themselves. We use this approach to revisit the importance of shocks to oil supply and demand. Supply disruptions turn out to be a bigger factor in historical oil price movements and inventory accumulation a smaller factor than implied by earlier estimates. Supply shocks lead to a reduction in global economic activity after a significant lag, whereas shocks to oil demand do not.

Service providers in Berlin give boost to East German economy – implications of the Joint Economic Forecast and of official data on the East German economy in 2018
In its spring report, the Joint Economic Forecast group states that the upturn in Germany came to an end in the second half of 2018, mainly because the manufacturing sector is weakening due to a slowing international economy and to problems in the automotive industry. Accordingly, in places such as Saxony (1.2%), Thuringia (0.5%), and Saxony-Anhalt (0.9%), where manufacturing plays a particularly important role, gross domestic product (GDP) grew less than in Germany as a whole (1.4%).

Bank profitability increases after eliminating consolidation barriers
When two banks merge because political consolidation barriers are abolished, the combined entity is considerably more profitable and useful to the real economy. This is the headline result of an analysis of compulsory savings banks mergers carried out by the Halle Institute for Economic Research (IWH). The study yields important insights for the German and the European banking market.

Private Equity and Financial Fragility During the Crisis
Shai B. Bernstein, Josh Lerner, Filippo Mezzanotti
Review of Financial Studies,
No. 4,
2019
Abstract
Does private equity (PE) contribute to financial fragility during economic crises? The proliferation of poorly structured transactions during booms may increase the vulnerability of the economy to downturns. During the 2008 crisis, PE-backed companies decreased investments less than did their peers and experienced greater equity and debt inflows, higher asset growth, and increased market share. These effects are especially strong among financially constrained companies and those whose PE investors had more resources at the crisis onset. In a survey, PE firms report being active investors during the crisis and spending more time working with their portfolio companies.

German economy will pick up speed only slowly
In winter of 2018/2019, the global economy weakened considerably, mainly due to economic policy risks. In Germany, the economy will pick up speed only slowly. According to IWH spring economic forecast, gross domestic product will increase by 0.5% in 2019. Growth in East Germany will amount to 0.7%.

New IWH publication takes stock: “United country – three decades after the Wall came down”
How is Germany’s economy faring 30 years after the fall of the Berlin Wall? A new publication by the Halle Institute for Economic Research (IWH) uses illustrative maps and graphs to show how the Federal Republic has developed compared to other countries and how economic unification has progressed. The publication presents many new findings, including on productivity differences between east and west, urban and rural development, as well as the availability of skilled labour.

United Country – Three Decades After the Wall Came Down
One-off Publications,
2019
Abstract
The Berlin Wall, once the symbol of the divided Germany, has now been gone for longer than it ever existed. But the differences within the country are still visible. However, recent research suggests that different economic development does not always follow the former inner-German border. Apart from the west-east divide, differences also emerge between the south and the north or between the cities and the country.

No-deal Brexit would hit the German labour market particularly hard
The United Kingdom leaving the European Union without a deal would have consequences for international trade and labour markets in many countries, including outside Europe. Calculations by the Halle Institute for Economic Research (IWH) indicate: More than 600,000 jobs may be affected worldwide, but nowhere as many as in Germany.

How Do Banks React to Catastrophic Events? Evidence from Hurricane Katrina
Claudia Lambert, Felix Noth, Ulrich Schüwer
Review of Finance,
No. 1,
2019
Abstract
This paper explores how banks react to an exogenous shock caused by Hurricane Katrina in 2005, and how the structure of the banking system affects economic development following the shock. Independent banks based in the disaster areas increase their risk-based capital ratios after the hurricane, while those that are part of a bank holding company on average do not. The effect on independent banks mainly comes from the subgroup of highly capitalized banks. These independent and highly capitalized banks increase their holdings in government securities and reduce their total loan exposures to non-financial firms, while also increasing new lending to these firms. With regard to local economic development, affected counties with a relatively large share of independent banks and relatively high average bank capital ratios show higher economic growth than other affected counties following the catastrophic event.
