Japan’s economy was expected to post a second straight quarter of moderate growth in January-March, led by a pickup in exports and business investment, a Reuters poll found, pointing if realized to a steady recovery from recession after last year’s sales tax hike. Annual expansion of 1.5 percent in gross domestic product (GDP) would match the rate of growth in October-December, translating into a quarterly increase of 0.4 percent, unchanged from the prior quarter, the Reuters poll of 22 economists found.
