Synopsis

Explore how households derive value from money and liquid assets, not just from consumption. This study presents a unified way to model asset demands that treats liquidity as a direct source of utility, alongside consumption.

The authors build a representative consumer model that includes four major asset classes—money, time deposits, short-term government debt, and corporate equity—and examine how these holdings interact with consumption. They estimate a utility-based framework using instrumental variables and test whether liquidity services are a real part of utility, not just a byproduct of other theories. The work also discusses estimation challenges, model identifiability, and how the results stack up against previous studies.


  • How the theory connects consumption, asset holdings, and liquidity services in a single framework

  • Estimation methods, overidentifying restrictions, and what the data say about utility from liquidity

  • Key findings on the share of spending devoted to consumption and the elasticity of substitution among assets

  • Implications for interpreting asset demand and for comparing with earlier models



Ideal for readers interested in monetary economics, asset demand, and empirical methods that link consumption with portfolio choices.
