Expected inflation is the major topic of this book. Yet, as we have noted before, the approach of pattern-based expectations can be applied to other macroeconomic variables as well. The second key variable besides inflation expectations that we have introduced and studied is the expected income. More concretely, Chapter 3 documents the laboratory data concerning subjective expectations of real GDP for patterns of length four.1 In this chapter, the generalized approach set out in Chapter 10 is extended to the case of income expectations. Accordingly, a new group of subjects sees the 25 possible patterns of length three, together with the information that the variable in question depicts the real GDP.2 Otherwise, the same instructions known from treatment (iii) are used again.
