In a two-sector model with circulating capital, Laibman (1982) shows that a capital-using and labor-saving technical change in the consumption goods sector lowers the rate of profit under the assumption of constant rate of exploitation. This paper generalizes his finding in a two-department multi-sector model that considers the capital advanced.
