In this paper, I demonstrate that an expanding variety model of endogenous growth with temporary monopoly power exhibits the indeterminacy of equilibrium paths. This implies the existence of a global range of initial growth rates for any initial level of the state variable.

In this note we introduce a family of functions that various theoretical results have revealed as useful mobility measures. These functions have enabled us to circumvent an impossibility result obtained by Shorrocks (1978), by adapting one of his axioms to the context of mobility as movement. A...
