The incremental capital output ratio (ICOR) is a key economic indicator that measures the efficiency of capital investment in generating output growth. It is widely used to assess the relationship between capital formation and economic development across different countries. ICOR is calculated by dividing the incremental capital investment by the incremental output. Thus, incremental capital output ratio (ICOR) serves as a valuable tool for evaluating the efficiency of capital investments and their impact on output growth.

Analyzing the incremental capital-output ratio by country provides valuable insights into the efficiency and productivity of capital investments on a global scale. By comparing ICOR values between countries, it becomes possible to identify disparities in resource allocation and the effectiveness of investment strategies. Countries with a low ICOR yield a higher output growth per unit of investment, indicating more efficient resource utilization.

The incremental capital output ratio yield, or the amount of output generated per unit of investment, is an essential metric for policymakers and economists. A higher yield signifies that a smaller investment can yield a relatively greater output. Countries with a high ICOR yield tend to experience faster economic growth and are considered attractive investment destinations due to their potential for higher returns. On the other hand, a lower ICOR yield suggests that more investment is required to generate the same level of output. This can be an indication of inefficiency in resource allocation or structural constraints within the economy. Governments and policymakers in countries with a lower ICOR yield often strive to implement reforms and policies aimed at improving the efficiency of capital investments to boost output growth.

Another useful measure related to ICOR is the incremental capital output ratio Z score. The ICOR Z score represents the relative position of a country's ICOR within a larger dataset, often accounting for the average ICOR and its standard deviation. This score helps identify outliers and countries with exceptional performance in terms of capital productivity. A positive ICOR Z score suggests that a country's ICOR is better than the average, indicating high efficiency in capital allocation. Conversely, a negative ICOR Z score implies that a country's ICOR is worse than the average signaling potential inefficiencies in resource utilization. By examining the ICOR Z score, policymakers and researchers understand a country's position with its peers and can identify areas for improvement.
