摘要:
This paper studies rational bubbles in dynamic stochastic general equilibrium models of the macroeconomy. The term ‘rational bubbles’ refers to multiple equilibria arising from the absence of a transversality condition (TVC) for capital. The lack of TVC can be due to an overlapping generations structure. Rational bubbles reflect self-fulfilling fluctuations in agents’ expectations about future investment. The rational bubbles considered here exhibit boom bust cycles of aggregate investment and output. Rational bubbles can generate persistent fluctuations of real activity, and capture key business cycle stylized facts.
