Below is a reminder of the difference between physical and human capital:
Table 1: The Difference Between Physical and Human Capital
Physical Capital Physical capital encompasses all human-made resources strategically employed to produce various goods and services. This category includes various tools, tractors, machinery, buildings, factories, and more. These tangible assets play a pivotal role in enhancing the effciency and scope of production processes, thereby contributing to economic growth.
Human Capital
Human capital, on the other hand, delves into the intangible yet immensely valuable sphere of skills and knowledge that workers accumulate over time through education and hands-on experience. This accumulation of expertise includes educational achievements like college degrees and vocational training, etc . Human capital signifcantly elevates workforce productivity, innovation, and adaptability, making it a driving force behind economic advancement.
● The Quantity and Quality of Labor: Improvements in human capital through education, training, and enhanced healthcare increase labor productivity (the output per worker) and contributetohighereconomicgrowth.Moreover,aslongasthecapitalperworkerratiodoesnot decrease,anincreaseinthequantityoflaborresultsinmoreproductionandhigheroutput.

Technology improves when more is spent on research and development (R&D). The higher the spending on R&D and technology, the higher the capital accumulation leading to higher rates of economic growth.
