Recently, nongovernmental organizations have engaged in debt-for-natur
e swaps in an effort to slow the rate of deforestation. The purpose of
this paper is to provide analysis of the welfare properties that aris
e to self-enforcing swaps, We show that swaps may be self-enforcing in
that they can arise as noncooperative equilibria at high harvest and
debt levels. Under these conditions, a credit constrained LDC is likel
y to reduce harvest levels. Similarly if the NGO views preservation pr
ojects as complements, it is likely to provide debt relief. We provide
simulations to demonstrate the effects of different parametric values
for the utility functions of the LDC and NGO on the noncooperative an
d cooperative equilibria.
