De klassieke dynamiek van Ricardo

In 1817, David Ricardo expanded on Smith and Malthus’s ideas with his book Principles of Political Economy and Taxation. He focused on how economic growth is affected by land scarcity, capital accumulation, and rent.

Imagine a growing agricultural economy. As the population increases, farmers expand to less fertile land. This leads to the law of diminishing returns, where output increases at a decreasing rate. Ricardo argued that landowners benefit: as food prices rise, rents on the best land increase, giving them a larger income share.

Meanwhile, capitalists who invest in tools and labor see their profits shrink. Rising wages, driven by higher food prices, cut into their returns. Ricardo believed this process would eventually lead to a “stationary state”—investment stops, profits disappear, and growth halts. His theory highlights conflict among landowners, workers, and capitalists in a land-scarce economy.

While this prediction ultimately proved inaccurate due to technological progress, Ricardo’s most impactful and enduring legacy lies in his theory of comparative advantage and international trade.
