Zeitalter der Mammutprojekte

WASHINGTON, DC – Wir scheinen derzeit in ein neues Zeitalter der Mammutprojekte einzutreten. Viele Länder, insbesondere die G20-Länder, mobilisieren den privaten Sektor, um in großem Umfang in viele Millionen (wenn nicht gar Milliarden oder Billionen) Dollar schwere Infrastrukturinitiativen – Pipelines, Staudämme, Wasser-, Strom- und Straßennetze usw. – zu investieren.

Schon jetzt belaufen sich die Ausgaben für Mammutprojekte auf rund 6-9 Billionen Dollar jährlich, etwa 8% vom weltweiten BIP. Damit ist dies der „größte Investmentboom der Geschichte“. Und die Geopolitik, das Streben nach Wirtschaftswachstum, Bemühungen um die Erschließung neuer Märkte sowie die Suche nach natürlichen Rohstoffen treiben immer mehr Geld in große Infrastrukturprojekte. An der Schwelle zu dieser potenziell beispiellosen, explosionsartigen Vermehrung derartiger Projekte scheinen Politik und Kreditgeber die kostspieligen Lehren der Vergangenheit weitgehend unbeachtet zu lassen.

Sicher können Investitionen in die Infrastruktur echte Bedürfnisse befriedigen und helfen, den erwarteten steilen Anstieg der Nachfrage nach Lebensmitteln, Wasser und Energie zu befriedigen. Doch sofern die explosionsartige Zunahme von Mammutprojekten nicht sorgsam umgelenkt und gesteuert wird, dürften die Bemühungen kontraproduktiv und nicht nachhaltig sein. Ohne demokratische Kontrolle werden die Investoren möglicherweise die Gewinne privatisieren, die Verluste vergesellschaften und zugleich dauerhaft kohlenstoffintensive und andere für Umwelt und Gesellschaft schädliche Ansätze etablieren.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
