In this paper, we study the effect of financial markets on the investment of a two-good two-country economy with stochastic production in a dynamic framework. Each country produces and invests only one good and, therefore, makes decisions as a central planner in an optimal growth model. Trade between consumers of both countries, however, takes place on competitive (spot or financial) markets. We compare the investment-consumption decisions of both `market' models with the benchmark-case of an integrated world-equilibrium. In the log-linear case, we can uniquely characterize the state-dependent preferences of consumers that lead to dynamically efficient investment decisions. We show that the investment decisions in both `market' models are, in general, inefficient as compared with the efficient, or integrated world economy, case.
