• The world economy is booming. The global upswing is investment-driven, and since investment goods usually have a large import content, it is no surprise that world trade has been buoyant during winter. The very expansionary US fiscal policy (tax reform and lifting of spending caps) could give an additional shortterm stimulus for the world economy. • However, we forecast world trade to slow down during 2018. The US administration’s announcement of high tariffs on steel and aluminium comes close to triggering a spiral into a broader trade conflict. Moreover, the globalization of value chains has been slowing down since the financial crisis due to the industrial upgrading in China and in other emerging economies that has declined processing trade. In addition, some types of manufacturing jobs have returned to source countries (reshoring) in response to technology innovation and lower labour costs differentials. • The euro area is in the middle of a broad based cyclical upswing. Higher exports and improved expectations have induced firms to invest more into equipment, as capacity utilization has been above average for some time now and is still increasing, and financing costs are very low. However, recent soft indicators, but also industrial production have been surprisingly downbeat, and there was some turbulence in financial markets, which suggests some caution. • The ECB will probably stop its asset purchase program at the end of 2018, but only later in 2019 start raising interest rates. Fiscal policy in the euro area is slightly expansionary this year, and a notable fiscal stimulus in France and in Germany is to be expected for 2019. • Overall, we forecast euro area GDP to expand by 2.2% in 2018 and by 1.6% in 2019. Accelerating wage dynamics will, together with higher price setting powers of firms and the recent increase in oil prices, cause consumer price inflation rising to nearly to 2% in 2019. Uncertainty, is however substantial, as a slight slowdown cannot be ruled out, which would also impact inflation dynamics.

Der neue Tariflohnabschluss verheißt Positives für die 2,3 Millionen Beschäftigten des öffentlichen Dienstes von Bund und Kommunen: Rückwirkend zum 01.03.2018 erhalten sie 3,2%, ab dem 01.04.2019 weitere 3,1% und zum 01.03.2020 nochmals 1,1% mehr Lohn. Die Beschäftigten bis zur Entgeltgruppe 6 erhalten zudem eine Einmalzahlung von 250 Euro.

In 2017 the world economy is in an upswing, but consumer price inflation is still surprisingly low in advanced economies, and central banks will therefore keep key interest rates very low and financial conditions favorable for the rest of the year and, probably, for 2018. Global growth, though, will moderate a bit, since expansive policy measures in China have been reduced. As an early consequence, imports of emerging Asia were no more than stagnant during summer. The upswing in the euro area is broad based, both regionally and with respect to the different components of aggregate demand, as investment has recently picked up markedly, partly due to construction of dwellings. From the production side, the level of capacity utilization in the manufacturing sector is clearly above its long-term average and rising further. Inflation will not have reached the ECB’s target rate of below but close to 2% at the end of 2018. The trend of a growing participation rate in labour markets and the amount of part-time and low quality jobs are some reasons why overall wage and price dynamics are still very moderate; the appreciation of the euro, the incorporation of technical innovations and a possible change in the consumer preferences for low-cost products could be other reasons. We forecast a GDP growth rate of 2.3% for 2017 and 1.9% for 2018. This year’s strong pickup of world trade means that net exports will, in spite of rather strong domestic demand, contribute positively to GDP growth in 2017, while the opposite holds for 2018, due to the significant appreciation of the Euro.

Global economic activity appears to be expanding rapidly during spring 2017. Confidence among managers is either strong or has improved in all major regions, and world trade and industrial production have, after two years of weakness, picked up markedly during last winter. For 2 ½ years, the euro area economy has now been constantly expanding at an annual rate of about 1.6%, slightly above potential. Employment has also been expanding steadily. Production and employment have been recently rising almost everywhere, including countries such as France and Italy where unemployment rates still do not appear to be on a downward trend. Official investment data for 2015 and 2016 appear to be distorted: big multinational firms relocated parts of their assets (intellectual property products in particular) or their registered business offices from countries outside the euro area to Ireland. As a consequence, reported gross fixed capital formation in Ireland expanded by 33% in 2015 and by 45% in 2016. Without this effect, investment growth in the euro area is about one percentage point lower in 2015 and 2016. Headline inflation hit 2% in February, but this was only the effect of higher world oil prices. The core rate is stubbornly at slightly below 1%, and wages rise annually by scarcely 1.5%. The revival of the economy will have to continue for considerably more time until inflation will come close to the ECB target zone. As monetary conditions continue to support growth, financial policies will be slightly expansive, and a certain external stimulus should come from the apparent recovery of world trade. Overall, we forecast euro area GDP to expand by 1.7% in both 2017 and 2018. However, policy uncertainty is substantial and could have a negative effect. In particular, elections in member states might give power to movements that aim at disintegrating Europe. Such a turn could rapidly undermine confidence, in particular in the financial strength of highly indebted member states.

This paper investigates the macroeconomic risks associated with undesirably low inflation using a medium-sized New Keynesian model. We consider different causes of persistently low inflation, including a downward shift in long-run inflation expectations, a fall in nominal wage growth, and a favorable supply-side shock. We show that the macroeconomic effects of persistently low inflation depend crucially on its underlying cause, as well as on the extent to which monetary policy is constrained by the zero lower bound. Finally, we discuss policy options to mitigate these effects.

We develop and estimate a general equilibrium search and matching model that accounts for key business cycle properties of macroeconomic aggregates, including labor market variables. In sharp contrast to leading New Keynesian models, we do not impose wage inertia. Instead we derive wage inertia from our specification of how firms and workers negotiate wages. Our model outperforms a variant of the standard New Keynesian Calvo sticky wage model. According to our estimated model, there is a critical interaction between the degree of price stickiness, monetary policy, and the duration of an increase in unemployment benefits.

The German government provides discretionary investment grants to structurally weak regions to reduce regional disparities. We use a regression discontinuity design that exploits an exogenous discrete jump in the probability of receiving investment grants to identify the causal effects of the investment grant on regional outcomes. We find positive effects for regional gross value-added and productivity growth, but no effects for employment and gross wage growth.

Ein Jahr nach Einführung des flächendeckenden gesetzlichen Mindestlohns in Höhe von 8,50 Euro brutto je Stunde ist die Diskussion über die Beschäftigungseffekte dieser Maßnahme in vollem Gange. Die momentan verfügbaren Daten deuten zwar nicht darauf hin, dass Arbeitsplätze in großem Umfang weggefallen sind, aber die wöchentliche Arbeitszeit Ungelernter ist in vom Mindestlohn besonders betroffenen Bundesländern gesunken.

Using linked employer–employee panel data for Germany, we investigate whether firms implement real wage reductions in a selective manner. In line with insider–outsider and several strands of efficiency wage theory, we find strong evidence for selective wage cuts with high-productivity workers being spared even when controlling for permanent differences in firms' wage policies. In contrast to some recent contributions stressing fairness considerations, we also find that wage cuts increase wage dispersion among peers rather than narrowing it. Notably, the same selectivity pattern shows up when restricting our analysis to firms covered by collective agreements or having a works council.

We show that the major part of the plant size–wage premium in Germany is reflected in different wage growth patterns in plants of different size. This is consistent with the hypothesis that large firms ‘produce’ more skilled workers over time.
