„Geh’n Sie mit der Konjunktur!“, so lautete der Refrain eines Gassen­hauers aus den soge­nannten Wirtschafts­wunder-Zeiten der noch jungen Bundes­republik. Doch hat die Konjunk­tur noch Konjunktur? Ist Konjunk­turpolitik (noch) sinnvoll, ist sie überhaupt relevant? Wenn nein, warum nicht? Wenn ja, unter wel­chen Voraus­setzungen? Welche Bedeutung haben Konjunk­turum­fragen für eine zuver­läs­sige und zugleich rasche Beurteilung der aktu­ellen wirtschaftlichen (i. e. „konjunk­turellen“) Lage? Haben solche Umfragen, wie sie beispiels­weise das Münchner ifo Institut, aber auch die Industrie- und Handels­kammern durchführen, Bedeutung für Wissenschaft und Forschung oder auch für die praktische Wirtschafts­politik? Wie steht es um das Verhältnis zwischen Konjunktur und Wachstum? Wie wichtig ist die Saison­bereinigung? Was genau verbirgt sich eigentlich hinter der „Geschäftslage“? Diese und ähnliche Fragen wurden auf einer Fachtagung diskutiert, zu der die Industrie- und Handels­kammer Halle-Dessau im April 2016 renommierte Konjunk­tur­forscher eingeladen hatte. Anlass war die Veröffent­lichung ihres 100. Konjunktur­berichts. Zu den Referenten zählten Klaus Abberger (Konjunk­turforschungs­stelle / KOF der ETH Zürich), Roland Döhrn (RWI – Leibniz-Institut für Wirtschafts­forschung, Essen) und Udo Ludwig (ehem. IWH – Leibniz-Institut für Wirtschafts­forschung Halle). Der vorliegende Sammel­band bringt die Referate und Diskus­sions­beiträge zusammen, ergänzt um Literatur­hinweise und Hinter­grund­informa­tionen. Deutlich wird: Konjunkturumfragen leisten wichtige Beiträge für Politik, Wissenschaft und selbst für Unternehmen: Aus den rasch vorliegenden Ergebnissen solcher Umfragen lassen sich Schlüsse für eine recht zuverlässige Beurteilung der aktuellen wirtschaft­lichen Situation wie auch für eine „bessere“ Wirtschafts­politik ziehen. Aber auch die Grenzen hinsichtlich Methodik und Reichweite von Unter­nehmens­umfragen werden thematisiert. Das Buch liefert eine wertvolle Bestands­auf­nahme – nicht nur für Experten, sondern auch und insbe­sondere für ökonomisch interessierte Laien.

Vermitteln subjektive Unternehmensurteile zum Geschäftsklima nur Stimmungsbilder oder sind sie auch ein verlässlicher Konjunkturindikator? Anhand einer Korrelationsanalyse wird der Nachweis geführt, dass ein statistisch signifikanter, positiver Zusammenhang zwischen den Unternehmensantworten und dem Konjunkturverlauf in der Region für die Gesamtheit der Unternehmen und für das produzierende Gewerbe besteht, nicht aber für die einzelnen Dienstleistungsbereiche.

Globalisation has greatly increased the degree of interdependence across countries. Macroeconomic policy must therefore take a global perspective, particularly in the case of small open economies such as Singapore. From a modeller’s point of view, this requires considering many countries, regions and markets, as well as multiple channels of transmission, including trade and financial linkages. Cross-country interdependencies are increasingly reflected in the effects of global shocks, to oil or food prices for example, as well as technology and policy uncertainty spillovers.

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.

We empirically analyse whether television (TV) can influence entrepreneurial identity and incidence. To identify causal effects, we utilise a quasi-natural experiment setting. During the division of Germany after WWII into West Germany with a free-market economy and the socialistic East Germany with centrally-planned economy, some East German regions had access to West German public TV that – differently from the East German TV – transmitted images, values, attitudes and view of life compatible with the free-market economy principles and supportive of entrepreneurship. We show that during the 40 years of socialistic regime in East Germany entrepreneurship was highly regulated and virtually impossible and that the prevalent formal and informal institutions broke the traditional ties linking entrepreneurship to the characteristics of individuals so that there were hardly any differences in the levels and development of entrepreneurship between East German regions with and without West German TV signal. Using both, regional and individual level data, we show then that, for the period after the Unification in 1990 which made starting an own business in East Germany, possible again, entrepreneurship incidence is higher among the residents of East German regions that had access to West German public TV, indicating that TV can, while transmitting specific images, values, attitudes and view of life, directly impact on the entrepreneurial mindset of individuals. Moreover, we find that young individuals born after 1980 in East German households that had access to West German TV are also more entrepreneurial. These findings point to second-order effects due to inter-personal and inter-generational transmission, a mechanism that can cause persistent differences in the entrepreneurship incidence across (geographically defined) population groups.

Ostdeutschland hat vom gegenwärtigen Aufschwung in Deutschland bisher besonders deutlich profitiert. In jedem der Aufschwungsjahre 2014 bis 2016 nahm die gesamtwirtschaftliche Produktion schneller zu als in Westdeutschland; auch für das Jahr 2017 prognostiziert das IWH, dass der Zuwachs der Produktion in Ostdeutschland mit 1,8% etwas höher liegt als in Westdeutschland. Freilich ist auch nach mehr als 25 Jahren Deutscher Einheit in jeder der ostdeutschen Regionen die Produktivität immer noch niedriger als in derjenigen westdeutschen Region mit der geringsten Produktivität. Der größte Teil der Zuweisungen vom Bund wird auch ab dem Jahr 2020, wenn der reformierte Länderfinanzausgleich gilt, in den Osten der Republik fließen. Die Reform des Länderfinanzausgleichs hat dabei nicht zu einer Verbesserung der wirtschaftspolitischen Anreize für die finanzschwachen Bundesländer geführt, was auch dazu beitragen könnte, dass die ökonomische Konvergenz nur schleppend verläuft.

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 study examines income convergence in regional GDP per capita for a sample of 269 regions within the European Union (EU) between 2003 and 2010. We use an endogenous broad capital model based on foreign direct investment (FDI) induced agglomeration economies and human capital. By applying a Markov chain approach to a new dataset that exploits micro-aggregated sub-national FDI statistics, the analysis provides insights into regional income growth dynamics within the EU. Our results indicate a weak process of overall income convergence across EU regions. This does not apply to the dynamics within Central and East European countries (CEECs), where we find indications of a poverty trap. In contrast to FDI, regional human capital seems to be associated with higher income levels. However, we identify a positive interaction of FDI and human capital in their relation with income growth dynamics.

A growing body of evidence indicates that the U.S. economy has become less dynamic in recent years. This trend is evident in declining rates of gross job and worker flows as well as declining rates of entrepreneurship and young firm activity, and the trend is pervasive across industries, regions, and firm size classes. We describe the evidence on these changes in the U.S. economy by reviewing existing research. We then describe new empirical facts about the relationship between establishment-level productivity and employment growth, framing our results in terms of canonical models of firm dynamics and suggesting empirically testable potential explanations.
