摘要: Sufficient conditions on the structure of technology that give rise to robust periodic cycles in stocks, outputs, and relative prices in a stationary, fully competitive economy with an infinitely lived representative agent are given. The results are first derived in the context of a general intertemporal model of accumulation that has been used in the turnpike literature. These results are then applied to a two-sector neoclassical model of production, and sufficient conditions giving rise to robust periodic cycles are obtained in terms of relative capital intensities of the two sectors.
