Finance theory suggests that leases and corporate debt are substitutes. How
ever, empirical evidence is mixed. The contribution of the present paper is
to test the substitution hypothesis for a sample of 1,066 large Belgian no
n-financial firms for the 1992-1994 period, considering different debt cate
gories, including intra-group loans. Belgium provides an interesting case t
o investigate the leasing decision because tax differences between lessor a
nd lessee do not matter. We find that long term bank debt and intra-group d
ebt are substitutes for lease financing. However, we do not find a one-to-o
ne relationship, which indicates that leases and long-term debt are not per
fect substitutes.
