Abstract

Recent empirical evidence suggests that product creation is pro-cyclical and it occurs largely within existing firms. Motivated by these findings, the current paper investigates the role of intra-firm product scope choice in a general equilibrium economy with oligopolistic producers. We show that the multi-product nature of firms makes the economy significantly more susceptible to sunspot equilibria. The estimated indeterminate model generates artificial business cycles that closely resemble empirically observed fluctuations.
