LACHMANN’S POLICY ACTIVISM‘plan complementarity’ or ‘designed complementarity’, which referto the relationship between elements <strong>in</strong> the firm’s plan, versus‘structural complementarity’—which refers to the relationship <strong>of</strong>elements across firms <strong>and</strong> <strong>in</strong>deed across <strong>in</strong>dustries, <strong>and</strong> thereforeacross plann<strong>in</strong>g consciousnesses. ‘Capital structure’ is given to bethe mode <strong>of</strong> complementarity expressed <strong>in</strong> the market as a whole, or‘a mode <strong>of</strong> the composition <strong>of</strong> the capital stock <strong>of</strong> society’ (Lachmann1986:63ff). In Capital <strong>and</strong> Its Structure, Lachmann dist<strong>in</strong>guishesbetween plan <strong>and</strong> structural complementarity along these l<strong>in</strong>es: ‘Thefirst type <strong>of</strong> complementarity is brought about directly byentrepreneurial action…. Our second type <strong>of</strong> complementarity is, ifat all, brought about <strong>in</strong>directly by the market, viz. by the <strong>in</strong>terplay<strong>of</strong> mostly <strong>in</strong>consistent entrepreneurial plans’ (Lachmann 1956:54,italics <strong>in</strong> orig<strong>in</strong>al). Aga<strong>in</strong>, <strong>in</strong> his last book The Market as an <strong>Economic</strong>Process, Lachmann draws the dist<strong>in</strong>ction:This second type <strong>of</strong> complementarity [here mean<strong>in</strong>g structuralcomplementarity] is not the direct result <strong>of</strong> planned action, butthe <strong>in</strong>direct result <strong>of</strong> the <strong>in</strong>teraction between the plans <strong>of</strong>different firms <strong>in</strong> the market. These latter plans need not havebeen consistent from the start, but were then made consistentby market forces.(Lachmann 1986:63)Structural complementarity is <strong>of</strong> the macro-level—on the order <strong>of</strong>the phenomena studied by policy makers; so is it valid to speak <strong>of</strong>policies on the macro-level, such as <strong>in</strong>creas<strong>in</strong>g the ‘level <strong>of</strong><strong>in</strong>vestment’, without mak<strong>in</strong>g reference to the coherence <strong>of</strong><strong>in</strong>dividual plans? If we follow Lachmann’s l<strong>in</strong>e <strong>of</strong> argument, we seeclearly that structural complementarity is a surface relationship orby-product, merely a manifestation <strong>of</strong> the dovetail<strong>in</strong>g (or failure todovetail) <strong>of</strong> <strong>in</strong>dividual plans, which are the more fundamental units<strong>of</strong> analysis. The morphology <strong>of</strong> capital at the structural level istherefore an order, which is to say that it is the result ‘<strong>of</strong> humanaction, but not <strong>of</strong> human design’—<strong>of</strong> <strong>in</strong>dividual <strong>and</strong> firm-level<strong>in</strong>vestment plann<strong>in</strong>g, but not <strong>of</strong> macroeconomic <strong>in</strong>vestment policy.To recognise this argument <strong>in</strong> Lachmann’s work is to drive thestake <strong>of</strong> subjectivism <strong>in</strong>to the heart <strong>of</strong> aggregate capital theory, <strong>and</strong>thus <strong>in</strong>to the heart <strong>of</strong> most arguments for macroeconomic<strong>in</strong>terventionism as well. This is because st<strong>and</strong>ard <strong>in</strong>vestment theoryfails to perceive the differences between conscious or <strong>in</strong>tended plancomplementarity at the firm level <strong>and</strong> manifested structural169
