The Internet Effects on Sex Crime Offenses – Evidence from the Broadband Internet Expansion in Germany

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.

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

Aktuelle Trends: Der Rückgang der Exporte nach Russland betrifft alle Bundesländer und ist nur zum Teil durch die Sanktionen der EU gegenüber Russland zu erklären
Oliver Holtemöller, Martina Kämpfe
Wirtschaft im Wandel,
No. 2,
2019
Abstract
In den vergangenen 20 Jahren waren die deutschen Exporte nach Russland in Relation zur gesamten Wertschöpfung zweimal rückläufig: zunächst im Jahr 2009 und dann wieder seit etwa dem Jahr 2012, also bevor die Europäische Union 2014 erstmals Handelssanktionen gegenüber Russland verhängte. Betroffen sind alle Bundesländer, der Rückgang dauert meist bis in die heutige Zeit an. Die Sanktionen dürften nur einen Teil des Rückgangs erklären. Vielmehr schwächte sich die Nachfrage nach Investitions- und Konsumgütern aus Russland mit dem Ölpreisverfall und der damit verbundenen Abwertung des Rubels Ende 2014 deutlich ab. Dies betraf nicht nur Deutschland, sondern beispielsweise auch China, das an Sanktionen gegenüber Russland nicht beteiligt ist. Erst 2016, als der Ölpreis wieder stieg, setzte eine teilweise Erholung der russischen Importe ein.

Weak foreign demand – economic downturn in Germany
In the summer of 2019, uncertainty due to ongoing trade disputes weighs on the global economy. The export-oriented German economy is particularly affected. According to IWH summer economic forecast, gross domestic product is expected to increase by only 0.5% in 2019; the forecast for East Germany is 0.8%. The German labour market remains largely robust despite the economic downturn.

Banks' Funding Stress, Lending Supply and Consumption Expenditure
H. Evren Damar, Reint E. Gropp, Adi Mordel
Abstract
We employ a unique identification strategy linking survey data on household consumption expenditure to bank-level data to estimate the effects of bank funding stress on consumer credit and consumption expenditures. We show that households whose banks were more exposed to funding shocks report lower levels of nonmortgage liabilities. This, however, only translates into lower levels of consumption for low income households. Hence, adverse credit supply shocks are associated with significant heterogeneous effects.

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%.

Mindestlohnbeschäftigte: Dienstleister für den privaten Konsum oder Teilhaber am Exporterfolg? Ergebnisse einer Input-Output-Analyse
Hans-Ulrich Brautzsch, Birgit Schultz
Wirtschaftsdienst,
No. 1,
2019
Abstract
Im Jahr 2014 waren mehr als 38 Mio. Personen in Deutschland als Arbeitnehmer beschäftigt. Sie produzierten vor allem Güter für den Konsum, für Investitionen in Ausrüstungen und Bauten sowie den Export, aber auch Vorleistungsgüter, die als Bestandteil der Wertschöpfungsketten indirekt in deren Entstehung eingingen. Hier ist wirtschafts- und lohnpolitisch interessant, in welchen quantitativen Verhältnissen der Einsatz der Beschäftigten in der Vorleistungsgüterproduktion zur Endverwendung im Wirtschaftskreislauf steht. Dieses Interesse richtet sich nicht nur auf die Personenzahl, sondern im Besonderen auch auf deren Entlohnung. Ein Augenmerk liegt dabei bei den Beschäftigten, deren Löhne 2014 dem Mindestlohn 2015 (8,50 Euro) entsprachen.

Economic activity in the world and in Germany is losing momentum
In the second half of 2018, the upturn of the German economy has stalled. Production of the automotive industry declined because of delays in switching production to WLTP compliant cars. Irrespectively of this, the German export business has been weakening since the beginning of the year, since the global economy, burdened by the political uncertainties surrounding trade conflicts, the impending Brexit and the conflict over the Italian budget, was unable to keep up with the high momentum of 2017. “It is to be expected that the less benign external environment will not only dampen exports, but will also impact on companies’ investment and hiring decisions”, says Oliver Holtemöller, head of the Department Macroeconomics and vice president at Halle Institute for Economic Research (IWH). Gross domestic product is expected to increase by 1.5% in 2018 and by 1.4% in 2019, which is roughly equal to the growth rate of economic capacity in Germany.

Should We Use Linearized Models To Calculate Fiscal Multipliers?
Jesper Lindé, Mathias Trabandt
Journal of Applied Econometrics,
No. 7,
2018
Abstract
We calculate the magnitude of the government consumption multiplier in linearized and nonlinear solutions of a New Keynesian model at the zero lower bound. Importantly, the model is amended with real rigidities to simultaneously account for the macroeconomic evidence of a low Phillips curve slope and the microeconomic evidence of frequent price changes. We show that the nonlinear solution is associated with a much smaller multiplier than the linearized solution in long-lived liquidity traps, and pin down the key features in the model which account for the di¤erence. Our results caution against the common practice of using linearized models to calculate scal multipliers in long-lived liquidity traps.

Housing Consumption and Macroprudential Policies in Europe: An Ex Ante Evaluation
Antonios Mavropoulos, Qizhou Xiong
IWH Discussion Papers,
No. 17,
2018
Abstract
In this paper, we use the panel of the first two waves of the Household Finance and Consumption Survey by the European Central Bank to study housing demand of European households and evaluate potential housing market regulations in the post-crisis era. We provide a comprehensive account of the housing decisions of European households between 2010 and 2014, and structurally estimate the housing preference of a simple life-cycle housing choice model. We then evaluate the effect of a tighter LTV/LTI regulation via counter-factual simulations. We find that those regulations limit homeownership and wealth accumulation, reduces housing consumption but may be welfare improving for the young households.
