What responsibilities do oil companies in Angola have to improve the situation of the Angolan population? Standard corporate social responsibility (CSR) projects have little effect where the rents from natural resources entrench the lack of democratic accountability. Since corporations help fuel the Angolan patronage system, this raises the question of whether companies also have a responsibility to address governance in the country. This chapter argues, on the basis of the assigned- responsibility model, that companies do have a responsibility to act to improve governance in Angola. The chapter also argues, however, that because oil companies gain from dysfunctional institutions, they do not adopt this kind of responsibility. Accordingly, incentives will be necessary to change corporate behavior.
