AbstractEmploying an overlapping generations model of R&D‐based growth with labour market frictions, this paper examines how employment changes induced by labour market frictions influence asset bubbles and long‐run economic growth. Asset bubbles can (cannot) exist when the employment rate is high (low), which leads to higher (lower) economic growth through labour market efficiency. We also explore the steady state and transitional dynamics of bubbles, economic growth and employment. Furthermore, we show that policy or parameter changes with a negative influence on the labour market can lead to a bubble burst.

A tractable model with infinitely lived agents is constructed for the examination of bubbles and unemployment. It is demonstrated that the presence of bubbles stimulates capital accumulation and reduces unemployment. The presence of bubbles also changes the effects of government policies that target unemployment and welfare conditions in the labor market. The main findings are as follows: (i) the presence of bubbles is more beneficial to an economy with severe credit constraints; (ii) the presence of bubbles mitigates the negative effects of taxation and unemployment benefits on unemployment and welfare; and (iii) these mitigation effects decrease as credit constraints are relaxed.
