Gross National Product (GNP) ???

The gross national product (GNP) refers to the value of all goods and services produced during a specific period of time, usually one year, plus the difference between foreign receipts and payments. The GNP is, therefore, identical to the concept of gross national income (GNI); hence, GNP =GNI. Thus, while the GNP is estimated on the basis of product flows, the GNI is estimated on the basis of money income flows, i.e. wages, profits, rent, interest, etc.
