To support its Beige Book efforts, the Chicago Fed gathers information from its business contacts using an online survey system. Respondents are asked to rate various aspects of business conditions along a seven-point scale ranging from “substantially increased” to “substantially decreased.” A series of diffusion indexes summarizing the distribution of responses is then calculated. Respondents’ respective average answers to a question can be interpreted as representing their historical trends or long-run averages. Thus, zero index values indicate that, on balance, activity, hiring, capital spending, or cost pressures are growing at their trend rates or that outlooks are neutral. Positive index values indicate above-average growth (or optimistic outlooks) on balance, and negative values indicate below average growth (or pessimistic outlooks) on balance.
