Mr. Barajas says a huge migration has driven this flow of money to countries around the world. But he says there are problems with governments receiving large amounts of money. They may use the money less effectively. Barajas先生说大批移民推动了这笔钱流向世界各地.但收到巨款的政府存在问题,政府的资金使用效率低下. Economists have said that remittances help families who receive them by increasing their income. But there is a concern that the income into a national economy will cause its money to increase in value. In turn, a country's exports can become more costly and less competitive. 经济学家称汇款增加了家庭收入,帮助了这些家庭.但是有人担忧入全国经济的收入会使货币增值,由此导致这个国家的出口费用将更贵、失去竞争力. __________________________
