Swofford and Whitney (1987) investigated the validity of two types of assumptions that underlie the representative agent models of modern macroeconomics and monetary economics. These assumptions are utility maximization and weak or functional separability that is required for an economic...

For previously identified weakly separable blockings of goods and assets, we construct aggregates using four superlative index numbers, the Fisher, Sato-Vartia, Törnqvist and Walsh, two non-superlative indexes, the Laspeyres and Paasche and the atheoretical simple summation. We conduct several...

We propose more general non-parametric revealed preference tests for weak separability and utility maximization with incomplete adjustment. Hence, these procedures account for a decision maker's inability to adjust his optimal allocation of the demanded goods and assets. Incomplete adjustment is...
