On the International Dissemination of Technology News Shocks
João Carlos Claudio, Gregor von Schweinitz
IWH Discussion Papers,
No. 25,
2020
Abstract
This paper investigates the propagation of technology news shocks within and across industrialised economies. We construct quarterly utilisation-adjusted total factor productivity (TFP) for thirteen OECD countries. Based on country-specific structural vector autoregressions (VARs), we document that (i) the identified technology news shocks induce a quite homogeneous response pattern of key macroeconomic variables in each country; and (ii) the identified technology news shock processes display a significant degree of correlation across several countries. Contrary to conventional wisdom, we find that the US are only one of many different sources of technological innovations diffusing across advanced economies. Technology news propagate through the endogenous reaction of monetary policy and via trade-related variables. That is, our results imply that financial markets and trade are key channels for the dissemination of technology.

The Value of Smarter Teachers: International Evidence on Teacher Cognitive Skills and Student Performance
Eric A. Hanushek, Marc Piopiunik, Simon Wiederhold
Journal of Human Resources,
No. 4,
2019
Abstract
We construct country-level measures of teacher cognitive skills using unique assessment data for 31 countries. We find substantial differences in teacher cognitive skills across countries that are strongly related to student performance. Results are supported by fixed-effects estimation exploiting within-country between-subject variation in teacher skills. A series of robustness and placebo tests indicate a systematic influence of teacher skills as distinct from overall differences among countries in the level of cognitive skills. Moreover, observed country variations in teacher cognitive skills are significantly related to differences in women’s access to high-skill occupations outside teaching and to salary premiums for teachers.

Downturn in Germany continues
Trade disputes are causing international trade in goods to decline this year. The manufacturing industry in Germany is particularly affected by this. However, a robust labour market is supporting the economy. According to IWH autumn economic forecast, German gross domestic product (GDP) will increase by 0.5% in 2019. At 1%, output growth in East Germany is likely to be significantly higher than in West Germany.

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.

Konjunktur aktuell: Schwache Auslandsnachfrage – Abschwung in Deutschland
Konjunktur aktuell,
No. 2,
2019
Abstract
Im Sommer 2019 deutet vieles darauf hin, dass die neuerliche Verschärfung der amerikanischen Handelspolitik den Welthandel und die internationale Konjunktur schwächt. Auf chinesische Waren sollen neue Zölle erhoben werden, und der weltwirtschaftlich stark verflochtene IT-Sektor wird durch die Genehmigungspflicht von Geschäften mit wichtigen chinesischen Anbietern der Telekommunikationstechnik belastet. Konjunktursorgen haben die Preise für wichtige Industriemetalle sowie für Erdöl sinken lassen. Mittlerweile erwarten die Finanzmärkte, dass die US-Notenbank ihren Leitzins im Herbst senken wird. Trotzdem dürfte der US-Aufschwung im Sommerhalbjahr zu Ende gehen, und für die Produktion im Euroraum ist für diesen Zeitraum mit einer Expansion unterhalb der Potenzialrate von knapp 1½% zu rechnen.
Von der Schwäche des Welthandels ist die international stark vernetzte deutsche Industrie besonders betroffen. Der deutliche Rückgang der Industrieproduktion im April lässt erkennen, dass die Belebung vom Jahresanfang vor allem auf temporäre Faktoren zurückging und die Grundtendenz der Konjunktur weiterhin schwach ist. Was die deutsche Konjunktur in diesem und wohl auch im nächsten Jahr stützen wird, ist die nach wie vor robuste Binnennachfrage. So bleibt der Zuwachs des privaten Konsums kräftig, denn die Einkommensentwicklung ist weiter positiv. Dazu trägt auch bei, dass von der Finanzpolitik in diesem Jahr ein expansiver Impuls im Umfang von 0,7% in Relation zum Bruttoinlandsprodukt ausgeht.
Deutliche Lohnsteigerungen bei anhaltendem Beschäftigungsaufbau lassen die Lohnstückkosten stark steigen. Hohe Preissteigerungen bleiben aber auf die Bauwirtschaft beschränkt. Alles in allem liegt die Produktion nach vorliegender Prognose im Jahr 2019 um 0,5% höher als im Vorjahr, im Jahr 2020 steigt die Rate auch wegen der höheren Zahl an Arbeitstagen auf 1,8%. Die ostdeutsche Wirtschaft expandiert in diesem Jahr um 0,8% und im Jahr 2020 um 1,7%.

Potential International Employment Effects of a Hard Brexit
Hans-Ulrich Brautzsch, Oliver Holtemöller
Abstract
We use the World Input Output Database (WIOD) to estimate the potential employment effects of a hard Brexit in 43 countries. In line with other studies we assume that imports from the European Union (EU) to the UK will decline by 25% after a hard Brexit. The absolute effects are largest in big EU countries which have close trade relationships with the UK like Germany and France. However, there are also large countries outside the EU which are heavily affected via global value chains like China, for example. The relative effects (in percent of total employment) are largest in Malta and Ireland. UK employment will also be affected via intermediate input production. Within Germany, the motor vehicle industry and in particular the “Autostadt” Wolfsburg are most affected.

The Effect of the Single Currency on Exports: Comparative Firm-level Evidence
Tibor Lalinsky, Jaanika Meriküll
IWH-CompNet Discussion Papers,
No. 1,
2019
Abstract
We investigate how adopting the euro affects exports using firm-level data from Slovakia and Estonia. In contrast to previous studies, we focus on countries that adopted the euro individually and had different exchange rate regimes prior to doing so. Following the New Trade Theory we consider three types of adjustment: firm selection, changes in product varieties and changes in the average value of the exports that compose the exports of individual firms. The euro effect is identified by a difference in differences analysis comparing exports by firms to the euro area countries with exports to the EU countries that are not members of the euro area. The results highlight the importance of the transaction costs channel related to exchange rate volatility. We find the euro has a strong pro-trade effect in Slovakia, which switched to the euro from a floating exchange rate, while it has almost no effect in Estonia, which had a fixed exchange rate to the euro prior to the euro changeover. Our findings indicate that the euro effect manifested itself mainly through the intensive margin and that the gains from trade were heterogeneous across firm characteristics.

Does Intermunicipal Cooperation Increase Efficiency? A Conditional Metafrontier Approach for the Hessian Wastewater Sector
F. Blaeschke, Peter Haug
Local Government Studies,
No. 1,
2018
Abstract
This paper analyses the relationship between intermunicipal cooperation and efficiency of public service provision. Organisational arrangements of public service production, including self-provision, joint provision or contracting, affect incentives and internal transaction costs. Hence, cooperation gains from scale effects need to be balanced against technical inefficiencies. We analyse relative efficiency of wastewater disposal for German municipalities. We employ a conditional analysis in conjunction with a metafrontier approach to calculate relative efficiency measures and technology gap ratios controlling for organisational arrangements and further environmental variables. Jointly providing municipalities and contractor municipalities exhibit lower technical efficiency than self-providing and contracting municipalities. As confirmed by previous research, scale effects from cooperation and contracting apply to small municipalities primarily.
