Het Innovatie enigma

NEW YORK – Over de hele wereld is er een enorm enthousiasme voor het soort technologische innovatie gesymboliseerd door Silicon Valley. In deze zienswijze representeert de Amerikaanse vindingrijkheid zijn ware comparatieve voordeel, dat anderen proberen te imiteren. Maar er is een raadsel: het is moeilijk om de voordelen van deze innovatie te detecteren in de bbp-statistieken.

Wat er vandaag de dag gebeurt is analoog aan ontwikkelingen enige tientallen jaren geleden, vroeg in het tijdperk van de personal computers. In 1987 klaagde de econoom Robert Solow (die de Nobelprijs kreeg voor zijn pionierswerk op het gebied van groei): ‘men kan het computertijdperk overal zien, behalve in de productiviteitsstatistieken’. Er zijn hier verschillende mogelijke verklaringen voor.

    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.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships.
