The famous book on economics, The Wealth of Nations, was written by Adam Smith.

Explanation:

The Wealth of Nations is the most famous work of Adam Smith. Published in 1776, it is considered the first modern book of economics.

Smith exposes his analysis on the origin of the prosperity of countries like England or the Netherlands. In it he develops economic theories about the division of labor, the market, currency, the nature of wealth, the price of goods in labor, wages, profits and the accumulation of capital. It examines different systems of political economy, in particular, mercantilism and physiocracy.

It is the founding document of classical economics and, without doubt, of economic liberalism.
