Benchmarks in Aggregate Household Portfolios
Reference-dependent preference models assume that agents derive utility from deviations of consumption from benchmark levels, rather than from consumption levels. These references can be either backward-looking (as explicit in the Habit literature) or forward-looking (as implicitly suggested by Prospect Theory). For both cases, we specify and estimate a fully structural multi-variate Brownian system in optimal consumption, portfolio and wealth using aggregate household financial and real estate wealth data. Our results reveal that references are (i) strongly relevant, (ii) state-dependent, and (iii) that the data is more consistent with the backward- than the forward-looking reference model.
