This study explores rational bubbles in a monetary economy using an endogenous growth model with status seeking. Rational bubbles may arise when the money growth rate is higher than some threshold level. In a bubbly economy, a higher money growth rate leads to a larger bubble size, while the monetary policy is super-neutral. However, in a bubbleless economy, the monetary policy is non-neutral. Based on a comparative analysis of the calibrated model, I argue that an optimal monetary policy that maximizes the social welfare of a bubbleless economy may trigger bubbles and hurt the economy.

Keywords: monetary policy; rational bubbles; status seeking
