This study advanced a social dilemma analysis to examine the role of s
elf-interested and prosocial concerns in the approval of a real-life s
tructural solution: the privatization of the the British national rail
way system in 1996. As predicted, disapproval of privatizing this publ
ic good increased when people were more concerned about the transition
costs of privatization, and about how privatization would affect thei
r personal outcomes (e. g., travel convenience) and the outcomes for t
he collective (e.g., railway accessibility). Moreover the approval of
privatization among people guided primarily by their self-interest (i.
e., pro-self individuals) was influenced more strongly by personal out
come concerns. Contrary to hypothesis, however prosocial individuals:
approval of privatization was not influenced more strongly by collecti
ve outcome concerns. Finally, people who disapproved of privatization
also exhibited a weaker intention to travel by train in the future, an
indication that the willingness to engage in collectively desirable b
ehavior may decrease when people fail to endorse a structural solution
