Intersectoral external effects, multiplicities & indeterminacies

This contribution focuses on the scope for indeterminacies that originate f rom global capital stock externalities in a reference two-sector growth mod el. A set of sufficient conditions for local indeterminacies and oscillatio ns is established and builds upon a new class of intersectoral dependency i n competitive economies, The uniqueness of the steady state is also questio ned and conditions for global indeterminacies are delimited. The underlying features of preferences and sectoral production technologies are assessed in this paper. It is shown that the principal attribute of a two-sector env ironment, i.e., a non-linear production possibility frontier, directly unde rlies indeterminacies. It is the influence of external effects on the relat ive price of the investment good that leads to these phenomena, a key role being detected in this perspective for external effects in the consumption good sector.
