Joint Economic Forecast Spring 2018: Germany’s Economic Experts Raise Forecast Slightly
Berlin, 19 April – Germany’s leading economic experts raised their forecasts for 2018 and 2019 slightly in their Spring Joint Economic Forecast released on Thursday in Berlin. They now expect economic growth of 2.2 percent for this year and 2.0 percent for 2019, versus 2.0 percent and 1.8 percent respectively in their autumn forecast. “The German economy is still booming, but the air is getting thinner as unused capacities are shrinking“, notes Timo Wollmershaeuser, ifo Head of Economic Forecasting. Commenting on the new German government’s economic policy, he adds: “It is precisely when the government’s coffers are full that fiscal policy should reflect the implications of its actions for overall economic stability and the sustainability of public finances. The extension of statutory pension benefits outlined in the coalition agreement runs counter to the idea of sustainability.”

Progressive Tax-like Effects of Inflation: Fact or Myth? The U.S. Post-war Experience
Matthias Wieschemeyer, Bernd Süssmuth
IWH Discussion Papers,
No. 33,
2017
Abstract
Inflation and earnings growth can push some tax payers into higher brackets in the absence of inflation-indexed schedules. Moreover, inflation may affect the composition of individuals’ income sources. As a result, depending on the relative tax burden of labour and capital, inflation may decrease or increase the difference between before-tax and after-tax income. However, whether some and if so which percentiles of the income distribution net benefit from inflation via taxation is a widely unexplored question. We make use of a novel dataset on U.S. pre-tax and post-tax income distribution series provided by Pike ty et al. (2018) for the years 1962 to 2014 to answer this question. To this end, we estimate local projections to quantify dynamic effects. We find that inflation shocks increase progressivity of taxation not only contemporaneously but also with some repercussion of several years after the shock. While particularly the bottom two quintiles gain in share, it is not the top but the fourth quintile that lastingly loses.

Abstract
Applying the growth accounting model the impact of labor and capital inputs as well as of the technological progress on GDP growth in different historical periods oft Eastern Germany is estimated. The main finding is the failure of the central planning model to modernize the economy. The total factor productivity dominated the economic growth only during the economic reforms in the second halve of the 60ies.

Benchmark Value-added Chains and Regional Clusters in R&D-intensive Industries
Reinhold Kosfeld, Mirko Titze
International Regional Science Review,
No. 5,
2017
Abstract
Although the phase of euphoria seems to be over, policy makers and regional agencies have maintained their interest in cluster policy. Modern cluster theory provides reasons for positive external effects that may accrue from interaction in a group of proximate enterprises operating in common and related fields. Although there has been some progress in locating clusters, in most cases only limited knowledge on the geographical extent of regional clusters has been established. In the present article, we present a hybrid approach to cluster identification. Dominant buyer–supplier relationships are derived by qualitative input–output analysis from national input–output tables, and potential regional clusters are identified by spatial scanning. This procedure is employed to identify clusters of German research and development-intensive industries. A sensitivity analysis reveals good robustness properties of the hybrid approach with respect to variations in the quantitative cluster composition.

Abstract
The paper analyzes the crucial events and political strategies driving the economic history of the former GDR. Applying the growth accounting model I estimate the impact of labor and capital inputs as wells as of the technological progress on GDP growth in different time periods. The main finding is the dominant role of total factor productivity in economic growth only during the economic reforms in the second halve of the 60ies.

Joint Economic Forecast Spring 2017: Upturn in Germany strengthens in spite of global economic risks
The German economy is already in the fifth year of a moderate upturn. According to the Gemeinschaftsdiagnose (GD, joint economic forecast) that was prepared by Germany’s five leading economic research institutes on behalf of the Federal Government, capacity utilization is gradually increasing, and aggregate production capacities are now likely to have slightly exceeded their normal utilisation levels. However, cyclical dynamics remain low compared to earlier periods of recoveries, as consumption expenditures, which do not exhibit strong fluctuations, have been the main driving force so far. In addition, net migration increases potential output, counteracting a stronger capacity tightening. “Gross domestic product (GDP) is expected to expand by 1.5% (1.8% adjusted for calendar effects) and 1.8% in the next year. Unemployment is expected to fall to 6.1% in 2016, to 5.7% in 2017 and 5.4% in 2018”, says Oliver Holtemöller, Head of the Department Macroeconomics and vice president of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association. Inflation is expected to increase markedly over the forecast horizon. After an increase in consumer prices of only 0.5% in 2016, the inflation rate is expected to rise to 1.8% in 2017 and 1.7% in 2018. The public budget surplus will reduce only modestly. Public finances are slightly stimulating economic activity in the current year and are cyclically neutral in the year ahead.

Kalte Progression – Gefahr für die Stabilität der Schuldenbremse
Götz Zeddies
Wirtschaft im Wandel,
No. 5,
2016
Abstract
Geringfügige Steuermehrbelastungen, die auf die kalte Progression bei der Einkommensteuer zurückzuführen sind, werden vom Steuerzahler kaum wahrgenommen und bieten dem deutschen Staat daher die Möglichkeit für schleichende Steuererhöhungen. Überschreiten die kumulierten Mehrbelastungen allerdings nach einigen Jahren eine kritische Schwelle, entsteht gewöhnlich ein politischer Druck für die Korrektur der kalten Progression. Wie im Beitrag gezeigt wird, kann die kalte Progression somit Auslöser eines Einnahmezyklus sein. Im Unterschied zu konjunkturbedingten Einnahmeschwankungen findet dieser Einnahmezyklus in den Regelungen zur Schuldenbremse keine Berücksichtigung. Ob die Regierungen eigenverantwortlich einen ausreichenden Sicherheitsabstand zur maximal zulässigen Nettokreditaufnahme einhalten, um diesen Schwankungen vorzubeugen, ist fraglich. Eine Indexierung des Steuertarifs, die eine automatische Korrektur der kalten Progression vorsieht, könnte derartige Schwankungen verhindern und für ein weniger volatiles Einkommensteueraufkommen sorgen.

Alternatives to GDP - Measuring the Impact of Natural Disasters using Panel Data
Jörg Döpke, Philip Maschke
Journal of Economic and Social Measurement,
No. 3,
2016
Abstract
A frequent criticism of GDP states that events that obviously reduce welfare of people can nevertheless increase GDP per capita. We use data of natural disasters as quasi experiments to examine whether alternatives to GDP (Human Development Index, Progress Index, Index of Economic Well-Being and a Happiness Index) lead to more plausible responses to disasters. Applying a Differences-in-Differences approach and estimates from various panels of countries we find no noteworthy differences between the response of real GDP per capita and the responses of suggested alternative welfare measures to a natural disaster except for the Human Development Index.

Innovation Network
Daron Acemoglu, Ufuk Akcigit, William R. Kerr
Proceedings of the National Academy of Sciences of the United States of America (PNAS),
No. 41,
2016
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.
