Most policy analysts implicitly relax the assumption that structural b
ottlenecks distinctively exist in developing economies. In this paper,
some bottlenecks are identified and modeled to augment a small model
of Uganda. The baseline and augmented model variants are estimated and
tested on aggregate data, 1963-85, and their results are compared. Th
e magnitudes and signs of the short-run estimates and long-run multipl
iers from the two variants show that bottlenecks constrain the potency
of stabilization policy. In general, the hypothesized effects of stru
ctural elements are validated for the aggregate supply and foreign bal
ance schedules of the economy, while orthodox budgetary and financial
policies are major players on the aggregate demand side. It is propose
d that policy makers in Uganda should pay more attention to supply-sid
e issues, especially with respect to the food and export sectors.
