In recent years, economists since the 1970s have sought to redefine the theory to make it more appropriate and relevant in modern economic societies. Proposed on the cusp of the First Industrial Revolution, it was motivated with single outputs in mind. The law of diminishing returns remains an important consideration in areas of production such as farming and agriculture. Diminishing returns are due to the disruption of the entire production process as additional units of labor are added to a fixed amount of capital. Ĭlassical economists such as Malthus and Ricardo attributed the successive diminishment of output to the decreasing quality of the inputs whereas Neoclassical economists assume that each 'unit' of labor is identical. In addition, at the end of the Napoleonic Wars, grain imports were restored which caused a decline in prices because the farmers needed to attract customers and sell their products faster. The four economists concluded that the prices of the products had risen due to the Napoleonic Wars, which affected international trade and caused farmers to move to lands which were undeveloped and further away.

These works were relevant to the committees of Parliament in England, who were investigating why grain prices were so high, and how to reduce them.

He argued that “each increase would be less and less productive.” In 1815, David Ricardo, Thomas Malthus, Edward West, and Robert Torrens applied the concept of diminishing returns to land rent. The law of diminishing returns can be traced back to the 18th century, in the work of Jacques Turgot. The concept of diminishing returns can be traced back to the concerns of early economists such as Johann Heinrich von Thünen, Jacques Turgot, Adam Smith, James Steuart, Thomas Robert Malthus, and David Ricardo. Together, these demonstrate diminishing returns from L 1. After L 1, the output per unit decreases to zero at L 3. Seen in, until an input of L 1, the output per unit is increasing. Input Seen in, the change in output by increasing input from L 1 to L 2 is equal to the change from L 2 to L 3. Similarly, it will begin to decline towards zero but not actually become a negative value, the same idea as in the diminishing rate of return inevitable to the production process.įigure 2: Output vs. Constraints such as resources will see the population growth stagnate at some point and begin to decline. The population size on Earth is growing rapidly, but this will not continue forever (exponentially). This idea can be understood outside of economics theory, for example, population. Innovation in the form of technological advances or managerial progress can minimise or eliminate diminishing returns to restore productivity and efficiency and to generate profit. Therefore, as a result of these constraints the production process will eventually reach a point of maximum yield on the production curve and this is where marginal output will stagnate and move towards zero.

These factors have the ability to influence economic growth and can eventually limit or inhibit continuous exponential growth. This example of production holds true to this common understanding as production is subject to the four factors of production which are land, labour, capital and enterprise. It is commonly understood that growth will not continue to rise exponentially, rather it is subject to different forms of constraints such as limited availability of resources and capitalisation which can cause economic stagnation. The concept of diminishing returns can be explained by considering other theories such as the concept of exponential growth. The law of diminishing returns is a fundamental principle of both micro and macro economics and it plays a central role in production theory. An example would be a factory increasing its saleable product, but also increasing its CO 2 production, for the same input increase. The modern understanding of the law adds the dimension of holding other outputs equal, since a given process is understood to be able to produce co-products. Under diminishing returns, output remains positive, but productivity and efficiency decrease.

The law of diminishing returns does not cause a decrease in overall production capabilities, rather it defines a point on a production curve whereby producing an additional unit of output will result in a loss and is known as negative returns. The law of diminishing returns (also known as the law of diminishing marginal productivity) states that in productive processes, increasing a factor of production by one unit, while holding all other production factors constant, will at some point return a lower unit of output per incremental unit of input. In economics, diminishing returns are the decrease in marginal (incremental) output of a production process as the amount of a single factor of production is incrementally increased, holding all other factors of production equal ( ceteris paribus).
