This article analyzes the effect of information generation and disclos
ure upon free-riding and on the likelihood that cooperative efforts co
llapse in a public-goods game. In this model the prospect of greater d
isclosure can make all individuals worse off ex ante by reducing expec
ted contributions to the public good. The model provides conditions un
der which disclosure becomes either more or less desirable as a functi
on of the number of individual contributors. Regulation or competitive
problems that increase direct costs of disclosure may on average incr
ease the provision of public goods and improve welfare. The desirabili
ty of disclosure in the contexts of collective political action, debt
renegotiation and production in teams are discussed.
