In fact, don't trust macroeconomists in general: individual preferences cannot be aggregated, at least not with our present mathematical tools. As a result, micro-founded macro models (99% of them) are complete nonsense: that's why Caltech doesn't even bother teaching macro to its PhD students anymore. It also explains why DSGE models have no predictive power whatsoever. Rant over.
