问题如下：

考点：Other Valuation Models
解析：根据定义式：economic income = cash flow – economic depreciation = cash flow + (ending market value – beginning market value)，两句话的表述都是正确的。
上课时候老师讲 Economic income=cash flow-（beginning market value-ending market value）
题目中：cash flow plus the change of market value，请问（beginning market value-ending market value）这部分的英文是什么？
