Title: Principles of Political Economy and Taxation
David Ricardo's On the Principles of Political Economy and Taxation the implications of land rent increases along with population among other things. Ricardo argues for the acceptance of free trade and shows how it's both short and long term advantages. The arguments laid out in this book form the basis of modern trade theory and are, therefore, of interest in today's global economy.
Ricardo suggested that there is mutual national benefit from trade even if one country is more competitive in every area than its trading counterpart and that a nation should concentrate resources only in industries where it has a comparative advantage, that is in those industries in which it has the greatest competitive edge.
