  • The more recessionary the economy, the more uncertainty about the future, the higher the liquidity preference.
  • Walras: "The sum of excess demand for the various commodities is zero."
    • Liquidity preference in the money market creates excess demand for money
    • This causes "lack of labor demand = unemployment" in the labor market.
