We show that dependence of production on foreign inputs (or non-producible natural resources) can significantly increase the likelihood of indeterminacy. Payment of imported foreign factors of production may act as a semi-fixed cost, amplifying production externalities and returns to scale, making selffulfilling expectations driven busyness cycles easier to arise. This is demonstrated using a s...
