Father of economics

Answer 1

If we think about economics as the science that studies why some countries are richer than others, then the father is Adam Smith.

On the other hand, the economics that dominate undergraduate studies today are based upon the problem of how to allocate scarce resources having infinite necessities, then I think the fathers will be the economists of the so-called Marginal Revolution(Jevons, Menger and Walras), followed by Alfred Marshall.
