Wikipedia (reference below) defines public finance as the study of the role of the government in the economy.
Wikipedia goes on to say:
[“Public finance] is the branch of economics which assesses the government revenue and government expenditure of the public authorities and the adjustment of one or the other to achieve desirable effects and avoid undesirable ones. The purview of public finance is considered to be threefold: governmental effects on (1) efficient allocation of resources, (2) distribution of income, and (3) macroeconomic stabilization.”
