This paper examines the general equilibrium consequences of temporary
and permanent trade policy interventions in circumstances where the pr
ice of non-tradeables endogenously adjusts to trade policy changes and
where there may be learning-by-doing externality effects in the trade
ables goods sector. Using a simple multisector, dynamic model, the pap
er demonstrates the difficulties of designing mixed and selective inte
rventions such that the ex-post real exchange rate and welfare outcome
s are in line with the ex-ante intent. (C) 1997 Elsevier Science Ltd.
