The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
This paper analyzes the borrowing behavior of a small open economy of a developing country that relies heavily on imports for its capital formation and faces an upward-sloping supply function of foreign loans. Decision makers face uncertainty about the longevity of external shocks. That uncertainty generates forecast errors that lead to substantial debt accumulation. It is found that the assumption of an upward-sloping supply function of foreign loans, which is a more realistic formulation for developing countries than the usual perfect elasticity, offers an alternative to the Uzawa-type utility function for analyzing asset accumulation in the small open economy framework.
