Liquidity Effects in Non‐Ricardian Economies

It has often been found difficult to generate a liquidity effect (i.e., a negative effect of monetary injections on the nominal interest rate) in the traditional “Ricardian” stochastic dynamic model with a single infinitely lived household. We show that moving to a non‐Ricardian environment where new agents enter the economy in each period allows such a liquidity effect to be generated.
