Abstract
Using administrative data for West Germany, this paper investigates whether part of the urban wage premium stems from greater competition in denser labor markets. We show that employers possess less wage-setting power in denser markets. We further document that an important part of the observed urban wage premia can be explained by greater competition in denser labor markets.

Power Generation and Structural Change: Quantifying Economic Effects of the Coal Phase-out in Germany

Energy Economics,
forthcoming
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 [6300; 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.

High public deficits not only due to the pandemic – Medium-term options for fiscal policy
According to the IWH’s medium-term projection, Germany's gross domestic product will grow more slowly between 2020 and 2025 than before, not only because of the pandemic crisis, but also because the work force will decline. The resulting structural public deficits are, if the legal framework remains unchanged, likely to be higher than the debt brake allows. Consolidation measures, especially if they relate to government revenues, entail economic losses in the short term. “There is much to be said, also from a theoretical point of view, for not abolishing the debt brake, but for relaxing it to some extent,” says Oliver Holtemöller, head of the Department of Macroeconomics and vice president at Halle Institute for Economic Research (IWH).

Konjunktur aktuell: Neue Pandemiewelle verzögert konjunkturelle Erholung in Deutschland
Konjunktur aktuell,
No. 4,
2020
Abstract
Während die Weltwirtschaft zweigeteilt ist – die Wirtschaft in Ostasien und in den großen Schwellenländern hat sich zügig erholt, für Nordamerika und Europa ist mit einem schwachen Winterhalbjahr zu rechnen –, lässt der Shutdown die Produktion in Deutschland zum Jahresende zurückgehen. Nach Lockerung der Infektionsschutzmaßnahmen, dank Impfkampagnen und milder Witterung dürfte die Erholung ab dem Frühjahr langsam wieder in Gang kommen. Im Jahr 2021 wird das BIP um 4,4% zunehmen, nach einem Rückgang um 5% im Jahr 2020. In Ostdeutschland fällt sowohl der Rückgang als auch der Wiederanstieg deutlich geringer aus.

Competition, Cost Structure, and Labour Leverage: Evidence from the U.S. Airline Industry
Konstantin Wagner
IWH Discussion Papers,
No. 21,
2020
Abstract
I study the effect of increasing competition on financial performance through labour leverage. To capture competition, I exploit variation in product market contestability in the U.S. airline industry. First, I find that increasing competitive pressure leads to increasing labour leverage, proxied by labour share. This explains the decrease in operating profitability through labour rigidities. Second, by exploiting variation in human capital specificity, I show that contestability of product markets induces labour market contestability. Whereas affected firms might experience more stress through higher wages or loss of skilled human capital, more mobile employee groups benefit from competitions through higher labour shares.

Recovery Loses Momentum ‒ Economy and Politics Still Shaped by the Pandemic
The corona pandemic leaves substantial marks in the German economy and its impact is more persistent than assumed in spring. In their autumn report, the leading German economic research institutes have revised their economic outlook downwards by roughly one percentage point for both this and next year. They now expect gross domestic product to fall by 5.4% in 2020 (previously -4.2%) and to grow by 4.7% (5.8%) in 2021 and 2.7% in 2022.

Economy recovers from the shutdown – but a quick return to pre-crisis normality is unlikely
The German economy has bounced back strongly over the summer, recovering a considerable part of the production slump caused by the shutdown in spring. Nevertheless, real gross domestic product in 2020 is likely to contract by 5.7%. In 2021, growth is expected to average 3.2% according to IWH autumn economic forecast. The decline in production in 2020 is likely to be less pronounced in East Germany com¬pared to Germany as a whole.

Abstract
Die Corona-Pandemie hat die Weltwirtschaft im ersten Halbjahr 2020 drastisch einbrechen lassen. Im Sommer wurden viele Aktivitäten aber wiederaufgenommen, und ein großer Teil des Einbruchs dürfte im zweiten Halbjahr wieder wettgemacht werden. Einige wirtschaftliche Aktivitäten wie der Tourismus oder Verkehrsdienstleistungen werden allerdings noch eine Weile eingeschränkt bleiben.

Labour Market Power and Between-Firm Wage (In)Equality
Matthias Mertens
IWH-CompNet Discussion Papers,
No. 1,
2020
Abstract
This study investigates how labour market power shapes between-firm wage differences using German manufacturing sector data from 1995 to 2016. Over time, firm- and employee-side labour market power, defined as the difference between wages and marginal revenue products of labour (MRPL), increasingly moderated rising between-firm wage inequality. This is because small, low-wage, low-MRPL firms possess no labour market power and pay wages equal to or even above their MRPL, whereas large, high-wage, high-MRPL firms possess high labour market power and pay wages below their MRPL. These wage-MRPL differences grow over time and compress the firm wage distribution compared to the counterfactual competitive labour market scenario. Particularly for the largest, highest-paying, and highest-MRPL firms, wage-MRPL differences strongly increase over time. This allows these firms to generate increasingly large labour market rents while being active on competitive product markets, providing novel insights on why such “superstar firms” are profitable and successful.
