Changing energy prices will normally have important long range implica
tions for an oil-importing country with a persisting trade deficit. Th
e availability of relatively expensive local energy can complicate the
issue further since developing such resources may save foreign exchan
ge but may be inefficient in the long run. This paper describes two no
nlinear programming models for energy policy analysis in which foreign
trade is considered within a one-sector representation of the economy
. A putty-clay technology is assumed as it is more representative of n
on-mature market economies which have to deal with such problems. The
models are capable of addresing energy issues in general as demonstrat
ed by results for Turkey.
