Against the background of the international debt problem which
originated with the oil shocks of the seventies, this book undertakes a
theoretical analysis of the factors determining aggregate external debt,
using the example of a raw material importing country. Instead of the
usual static definition of the trade balance as the difference between
the value of exports and imports in a single period, here an
intertemporal approach is used with a country's current account balance
determined as the difference between aggregate saving and aggregate net
investment, variables which are primarily dependent on expectations
about the future. The analysis is based on microeconomic optimization
models which enables individual causal relationships to be presented in
a detailed way, the "optimal" size of external debt to be determined and
the desirability of an immediate adjustment in the level of debt
following an external disturbance to be shown from a welfare point of
view.
