We develop a tractable rational bubbles model with financial frictions, downward nominal wage rigidity, and the zero lower bound. The interaction of financial frictions and nominal rigidities leads to a "bubbly pecuniary externality," where competitive speculation in risky bubbly assets can...

The two key questions which motivate our work are: do bubbles exist (in the sense that stock market prices do not always correspond to the present value of expected future profitability) and, if bubbles exist, do they have an effect on business fixed investment? The case of Japan is particularly...
