remains constant
"When workers already have a large quantity of capital to use in producing goods and services, giving them an additional unit of capital increases their productivity only slightly." This statement
represents the traditional view of the production process. is an assertion that capital is subject to diminishing returns. is made under the assumption that the quantities of human capital, natural resources, and technology are being held constant.
