Economic growth across the 19-country eurozone is showing signs of slowing, according to a survey conducted before any assessment of the impact on German industry of the emissions-rigging scandal engulfing carmaker Volkswagen, AP reported. Financial information company Markit said Wednesday its monthly purchasing managers' index a broad gauge of business activity fell to 53.9 points in September from 54.3 the previous month. Though anything above 50 indicates expansion, the decline points to slower growth. Markit says its survey points to quarterly growth of 0.4 percent in the third quarter, unchanged from the previous three-month period.
