Social Overhead Capital (SOC) refers to the essential public infrastructure and services that support economic activities and enhance the quality of life. Introduced by Hirofumi Uzawa in the 1970s, SOC includes capital goods that are available to all members of society and are not tied directly to a specific part of production. These assets are usually provided by the government due to their non-excludable and non-rivalrous nature.
Historical Context
Hirofumi Uzawa, a prominent Japanese economist, introduced the concept of SOC in the 1970s to emphasize the critical role of public infrastructure in economic development. Uzawa’s theory built on the foundations laid by earlier economists who studied public goods and their impact on economic growth.
