Adam Smith, considered to be the founding father of modern Economics, defined Economics as
the study of the nature and causes of nations’ wealth or simply as the study of wealth.
The central point in Smith’s definition is wealth creation. Implicitly, Smith identified
wealth with welfare. He assumed that, the wealthier a nation becomes the happier are its
citizens. Thus, it is important to find out, how a nation can be wealthy. Economics is the
subject that tells us how to make a nation wealthy. Adam Smith’s definition is a wealth-centred
definition of Economics.
