摘要:Business investment in advanced economies has been underwhelmingsince the 2007–09 global financial crisis, explained, in part, by slowergrowth in aggregate demand. A renewed period of weakness in investmentspending began in 2014, likely reflecting the impact of lower commodityprices and, most recently, a rise in economic uncertainty. In coming years, there is scope for growth in investment spending to pickup as the drag from low commodity prices and elevated uncertainty fades. But even as these headwinds recede, business investment growth islikely to remain slower than in the pre-crisis period largely because ofstructural factors. Such factors include slowing growth rates for populationand total factor productivity and an increasing share of services inthe economy.
