Abstract
This study analyses the performance of the International Monetary Fund (IMF) World Economic Outlook output forecasts for the world and for both the advanced economies and the emerging and developing economies. With a focus on the forecast for the current year and the next year, we examine the durability of IMF forecasts, looking at how much time has to pass so that IMF forecasts can be improved by using leading indicators with monthly updates. Using a real-time data set for GDP and for indicators, we find that some simple single-indicator forecasts on the basis of data that are available at higher frequency can significantly outperform the IMF forecasts as soon as the publication of the IMF’s Outlook is only a few months old. In particular, there is an obvious gain using leading indicators from January to March for the forecast of the current year.

Mittelfristprojektion des IWH: Wirtschaftsentwicklung und Öffentliche Finanzen 2018 bis 2025

Abstract
In Deutschland wird die Anzahl der Erwerbspersonen mittelfristig aufgrund der Alterung der Bevölkerung sinken und damit auch das Wirtschaftswachstum niedriger ausfallen als in den vergangenen Jahren. Gleichzeitig hat die Bundesregierung eine Reihe von zusätzlichen Staatsausgaben beschlossen. Auf der Grundlage einer gesamtwirtschaftlichen Projektion mit dem IWH-Deutschlandmodell lässt sich aber zeigen, dass es bis zum Jahr 2025 kaum zu Haushaltsdefiziten kommt, auch wenn sämtliche im Koalitionsvertrag enthaltenen finanzpolitischen Maßnahmen umgesetzt werden. Selbst wenn sich die makroökonomischen Rahmenbedingungen verschlechtern, etwa wegen eines deutlichen Zinsanstiegs oder eines Einbruchs der ausländischen Nachfrage, würde der Finanzierungssaldo zwar negativ, die zu erwartenden Defizite lägen aber dennoch wohl unter 0,5% in Relation zum Bruttoinlandspro-dukt. Ein Einbruch der ausländischen Nachfrage würde die Produktion zwar stärker dämpfen als ein Zinsschock, die Effekte auf den gesamtstaatlichen Finanzierungssaldo wären aber vergleichbar. Denn ein Zinsschock belastet eher die Binnennachfrage, von deren Rückgang die staatlichen Einnahmen stärker betroffen sind als von einem Rückgang der Exporte. Für die kommenden Jahre dürfte der deutsche Staatshaushalt damit recht robust sein; dabei ist aber zu beachten, dass etwa die aus dem Rentenpaket resultierenden Mehrausgaben erst nach dem Jahr 2025 deutlich zu Buche schlagen.

IWH leads large scale EU research project on productivity
Is productivity growth slowing in industrialised countries? And if so, why? From the start of 2019, the Halle Institute for Economic Research (IWH) will be addressing these questions as the coordinator of a new EU project. Economists and statistics experts from nine European partners will collaborate on the three-year project, entitled MICROPROD. With a total budget of just under three million euros, it is the IWH’s largest EU project to date.

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.

On the Risk of a Sovereign Debt Crisis in Italy

No. 6,
2018
Abstract
The intention for the Italian government to stimulate business activity via large increases in government spending is not in line with the stabilisation of the public debt ratio. Instead, if such policy were implemented, the risk of a sovereign debt crisis would be high. In this article, we analyse the capacity of the Italian economy to shoulder sovereign debt under different scenarios. We conclude that focusing on growth enhancing structural reforms, would allow for moderate increases in public expenditure.

Innovation, Reallocation, and Growth

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.

Connecting to Power: Political Connections, Innovation, and Firm Dynamics

NBER Working Paper,
No. 25136,
2018
Abstract
How do political connections affect firm dynamics, innovation, and creative destruction? To answer this question, we build a firm dynamics model, where we allow firms to invest in innovation and/or political connection to advance their productivity and to overcome certain market frictions. Our model generates a number of theoretical testable predictions and highlights a new interaction between static gains and dynamic losses from rent-seeking in aggregate productivity. We test the predictions of our model using a brand-new dataset on Italian firms and their workers, spanning the period from 1993 to 2014, where we merge: (i) firm-level balance sheet data; (ii) social security data on the universe of workers; (iii) patent data from the European Patent Office; (iv) the national registry of local politicians; and (v) detailed data on local elections in Italy. We find that firm-level political connections are widespread, especially among large firms, and that industries with a larger share of politically connected firms feature worse firm dynamics. We identify a leadership paradox: when compared to their competitors, market leaders are much more likely to be politically connected, but much less likely to innovate. In addition, political connections relate to a higher rate of survival, as well as growth in employment and revenue, but not in productivity – a result that we also confirm using a regression discontinuity design.
