measures by which a government attempts to influence the economy. The national budget generally reflects the economic policy of a government, and it is partly through the budget that the government exercises its three principal methods of establishing control: the allocative function, the stabilization function, and the distributive function.

Over time, there have been considerable changes in emphasis on these different economic functions of the budget. In the 19th century, government finance was primarily concerned with the allocative function. The job of government was to raise revenue as cheaply and efficiently as possible to perform the limited tasks that it could do better than the private sector. As the 20th century began, the distribution function acquired increased significance. Social welfare benefits became important, and many countries introduced graduated tax systems. In the later interwar period, and more especially in the 1950s and '60s, stabilization was central, although equity was also a major concern in the design of tax systems. In the 1970s and '80s, however, the pendulum swung back. Once more, allocative issues came to the fore, and stabilization and distribution became less significant in government finance.
