91热爆

The European Central Bank is expected to announce a massive asset-buying programme - otherwise known as quantitative easing, or QE - in an effort to revive the eurozone economy, but skeptics say it may not make much of a difference. The 91热爆's Andrew Walker explains the economics behind QE. We hear from Axel Weber, former president of Germany's central bank, the Bundesbank, and now chairman of UBS, and also from Andrew Sentance, formerly of the Bank of England's monetary policy committee, and now senior economic adviser to PricewaterhouseCoopers. Plus, we look at how the euro's buying power varies hugely throughout the eurozone with the Economist's finance editor, Ed McBride, and their latest Big Mac index.
