Understanding Embodied vs. Disembodied Technical Change    Disembodied Technical Change This refers to progress that is not tied to any specific factor of production. It is like manna from heaven that makes all existing capital and labor more productive simultaneously. In the standard Solow Model , technical change is typically represented as a shift in the production function, Y  At fK, L, affecting all K regardless of its age.   Embodied Technical Change This occurs when new technology can only be utilized through the introduction of new capital equipment. Older machines do not benefit from the new technology only the latest vintage of capital carries the improvement.        Why the Arrow Model 1962 fits  Kenneth Arrows model of Learning-by-Doing is a precursor to modern endogenous growth theory. He argued that   Technical change is a byproduct of experience in the production of capital goods.  Crucially, this knowledge is embodied in the design of new machinery.  As the economy accumulates more gross investment, it learns how to make better machines. Therefore, the productivity of the economy is linked to the vintage of its capital stock.        Analysis of Other Options    Solow-Swan A Primarily treats technical change as exogenous and disembodied though Solow later wrote on vintage capital models, his primary 1956 framework is disembodied.   Romer C While Romer endogenizes technology through RD, his 1990 model usually treats blueprints or ideas as a stock of knowledge A that increases the productivity of all intermediate goods sectors, making it closer to a disembodied or knowledge-spillover framework.   Lucas D Focuses on the accumulation of human capital H. While skills are embodied in people, the term embodied technical change in growth literature specifically refers to the link between technology and physical capital machinery.

Which of the following growth models is most closely associated with the concept of "embodied technical change," where technological progress is incorporated specifically into new capital goods rather than being a general improvement across all existing assets?
