Consider a manufacturing plant as an example of physical capital. Factor mobility with regard to this physical capital refers to
◦ the elasticity of supply of the labour employed in the plant.
◦ only the long-run concept of mobility because it is physical capital.
◦ the ease with which this plant can be converted to a different use.
◦ the ease with which the labour employed at the plant can be retrained to produce a different product.
◦ the ease with which this plant can be relocated to another location.
