Abstract: A person cannot make many decisions at a time, but an organization needs millions of interrelated decisions. We incorporate this idea into a standard theory of production. Two assumptions are emphasized: an agent cannot optimize more than one input at a time, and there is interaction among inputs. When a firm alternates its attention, the demand for inputs gradually adjusts to the static optimal level. When a firm optimally allocates its attention, this adjustment may not occur. We investigate the conditions under which the adjustment takes place. The results are applied to a standard investment theory. The derived investment-capital ratio is independent of firm size and imperfectly correlated with Tobin's Q.
