The ICOR - Incremental Capital Output Ratio, also known as the ICOR, is a tool that is frequently used to explain the connection between the level of economic investment and the subsequent rise in GDP. The additional unit of capital or investment required to produce an additional unit of output is indicated by ICOR. The relationship between the level of economic investment and the resulting increase in GDP is explained by the incremental capital output ratio (ICOR).A metric called ICOR measures how much investment capital is needed for a country or other entity to produce the next unit of production. A country's production efficiency is better reflected by a lower ICOR. Some people who don't like ICOR say that it's only used in limited ways because it favors developing countries that can use more technology and infrastructure than developed countries, which are doing their best.

The ICOR - Incremental Capital Output Ratio measures the smallest amount of investment capital required for a nation or another entity to produce the subsequent unit of production. A higher ICOR value is generally unfavorable because it suggests that the entity's production is inefficient. The measure is mostly used to figure out how efficient a country's production is. Some people who have criticized ICOR have said that its uses are limited because countries can only become so efficient with the technology they have. With a certain amount of resources, a developing nation could theoretically increase its GDP by a greater margin than a developed nation could. This is because a developing nation has room for improvement while a developed nation already operates with the highest level of technology and infrastructure. A developed nation would need to spend more money on research and development (R&D) in order to make any further advancement, whereas a developing nation could use the technology it already has to improve its situation. ICOR can be calculated as follows:

ICOR = Change in Capital / Change in GDP

Consider Country A, for instance, whose incremental capital output ratio (ICOR) is 10: This indicates that an additional Rs 1 in production necessitates a capital investment of Rs10. In addition, the fact that country A's ICOR was 12 last year indicates that the country has improved its capital utilization efficiency.

Limitations of the ICOR or, the Incremental Capital Output Ratio

There are numerous challenges to accurately estimating ICOR for advanced economies. Its inability to adapt to the new economy, which is increasingly driven by intangible assets like design, branding, software, and research and development (R&D), which are difficult to measure or record, is one of its primary criticisms. Compared to tangible assets like computers, buildings, and machinery, intangible assets are more difficult to account for in GDP and investment levels. Software-as-a-service (SaaS) and other on-demand options have significantly reduced the requirement for fixed asset investments. With the rise of "as-a-service" models for nearly everything, this can be extended even further. All of this adds up to businesses increasing production levels using items that are now expensed rather than capitalized and are therefore regarded as investments.

A Classic Illustration for the ICOR or, the Incremental Capital Output Ratio

The Indian economy was based on planning and implemented through the Five-Year Plans from 1947 to 2017.India's final five-year plan was the 12th Five-Year Plan, which was created by the Indian government. In the 12th Five-Year Plan, the Planning Commission of India determined the required investment rate for various growth outcomes. The investment rate at market price would need to be 30.5% for a growth rate of 8%, and it would need to be 35.8% for a growth rate of 9.5%.From 2007 to 2008, India's investment rates were 36.8 percent of GDP, but they fell to 30.8 percent in 2012 and 2013.The pace of development during a similar period tumbled from 9.6% to 6.2%.Clearly, India's growth declined more rapidly and abruptly during this time than investment rates did. Therefore, the decline in the Indian economy's growth rate must have been due to factors other than savings and investment rates. Otherwise, the economy is becoming less effective: India's GDP growth rate in 2019 was 4.23 percent, and the country's investment rate as a percentage of GDP was 30.21 percent.
