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.

Inference in Structural Vector Autoregressions when the Identifying Assumptions are not Fully Believed: Re-evaluating the Role of Monetary Policy in Economic Fluctuations
Christiane Baumeister, James D. Hamilton
Journal of Monetary Economics,
2018
Abstract
Point estimates and error bands for SVARs that are set identified are only justified if the researcher is persuaded that some parameter values are a priori more plausible than others. When such prior information exists, traditional approaches can be generalized to allow for doubts about the identifying assumptions. We use information about both structural coefficients and impacts of shocks and propose a new asymmetric t-distribution for incorporating information about signs in a nondogmatic way. We apply these methods to a three-variable macroeconomic model and conclude that monetary policy shocks are not the major driver of output, inflation, or interest rates.

Innovation, Reallocation, and Growth
Daron Acemoglu, Ufuk Akcigit, Harun Alp, Nicholas Bloom, William R. Kerr
American Economic Review,
No. 11,
2018
Abstract
We build a model of firm-level innovation, productivity growth, and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using US Census microdata on firm-level output, R&D, and patenting. The model provides a good fit to the dynamics of firm entry and exit, output, and R&D. Taxing the continued operation of incumbents can lead to sizable gains (of the order of 1.4 percent improvement in welfare) by encouraging exit of less productive firms and freeing up skilled labor to be used for R&D by high-type incumbents. Subsidies to the R&D of incumbents do not achieve this objective because they encourage the survival and expansion of low-type firms.

Within Gain, Structural Pain: Capital Account Liberalization and Economic Growth
Xiang Li, Dan Su
New Structural Economics Working Paper No. E2018010,
2018
Abstract
This paper is the first to study the effects of capital account liberalization on structural transformation and compare the contribution of within term and structural term to economic growth. We use a 10-sector-level productivity dataset to decomposes the effects of opening capital account on within-sector productivity growth and cross-sector structural transformation. We find that opening capital account is associated with labor productivity and employment share increment in sectors with higher human capital intensity and external financial dependence, as well as non-tradable sectors. But it results in a growth-reducing structural transformation by directing labor into sectors with lower productivity. Moreover, in the ten years after capital account liberalization, the contribution share of structural transformation decreases while that of within productivity growth increases. We conclude that the relationship between capital account liberalization and economic growth is within gain and structural pain.

Upturn Loses Momentum – World Economic Climate Grows Harsher
Roland Döhrn, Oliver Holtemöller, Stefan Kooths, Claus Michelsen, Timo Wollmershäuser
Wirtschaftsdienst,
No. 10,
2018
Abstract
The economic upturn in Germany is entering its sixth year but is losing momentum due to both demand and supply side factors. On the one hand, Germany’s key sales markets have weakened in line with the slowdown in world trade. On the other hand, a growing number of firms face production side bottlenecks, especially in terms of labour and sourcing intermediate goods. This coincides with problems in the automotive industry related to the introduction of the new World Harmonised Light Vehicle Test Procedure (WLTP), which has affected gross domestic product (GDP) growth due to the branch’s economic weight. These adjustment problems, however, should be overcome over the course of the winter. Fiscal stimuli will also take effect as of the beginning of 2019. After 1.7 % growth this year, GDP will increase at rates of 1.9 % in 2019 and 1.8 % in 2020.

Joint Economic Forecast Autumn 2018: Upturn Loses Momentum
Berlin, 27 September – Germany’s leading economics research institutes have downwardly revised their forecasts for 2018 and 2019. They now expect economic output to increase by 1.7 percent in 2018, and not 2.2 percent as forecast in spring. They also scaled back their 2019 forecast slightly from 2.0 to 1.9 percent. These are the results of the Joint Economic Forecast for autumn 2018 that will be presented in Berlin on Thursday.

Upturn Loses Momentum – World Economic Climate Grows Harsher: Joint Economic Forecast Autumn 2018
Externe Monographien,
No. 2,

Abstract
The economic upturn in Germany is entering its sixth year, but is losing momentum. This is due to both demand and supply side factors. On the one hand, Germany’s key sales markets have weakened in line with the slowdown in world trade. On the other hand, a growing number of companies are apparently facing production-side bottlenecks, especially in terms of labour and sourcing intermediate goods. This overlaps with problems in the automotive industry related to the introduction of the new World Harmonised Light Vehicle Test Procedure (WLTP), which has clearly impacted gross domestic product (GDP) growth due to the branch’s economic weight. Adjustment problems, however, should be overcome in the course of the winter half year. Stimuli from fiscal policy measures will also take effect as of the beginning of 2019. After 1.7% growth this year, economic output will increase at rates of 1.9% in 2019 and 1.8% in 2020. Employment will continue to expand clearly, although at a slower pace. The number of registered unemployed persons will approach the 2 million-mark by the end of the forecasting horizon. Inflation will pick up from an average rate of 1.8% this year to 2.0% in 2019 and 1.9% in 2020. Despite its expansionary fiscal stance, the German government will continue to post a budget surplus, although this can be expected to fall from 54 billion euros to around 40 billion euros.

Growth through Heterogeneous Innovations
Ufuk Akcigit, William R. Kerr
Journal of Political Economy,
No. 4,
2018
Abstract
We build a tractable growth model in which multiproduct incumbents invest in internal innovations to improve their existing products, while new entrants and incumbents invest in external innovations to acquire new product lines. External and internal innovations generate heterogeneous innovation qualities, and firm size affects innovation incentives. We analyze how different types of innovation contribute to economic growth and the role of the firm size distribution. Our model aligns with many observed empirical regularities, and we quantify our framework with Census Bureau and patent data for US firms. Internal innovation scales moderately faster with firm size than external innovation.

Current economic outlook: German upswing is slowing down
In summer 2018, the world economy is still rather strong. Dynamics in the euro area, however, have declined markedly, and the cyclical upswing in Germany has almost stalled, due to weaker exports. “Gross domestic product will, according to this forecast, expand by 1.7% in 2018 and by 1.6% in 2019. Growth in East Germany will be about as strong as in Germany as a whole”, says Oliver Holtemöller, head of the Department Macroeconomics and vice president at IWH.

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.”
