Friedman, Benjamin

Monetary policymakers normally seek to achieve multiple objectives: for prices as well as real economic activity, sometimes for the composition of real activity as well as the aggregate, and often for aspects of the economy's international balance. The fact that monetary policy has only one basic instrument to use therefore creates both complexity and tensions among these objectives. Although inflation targeting represents a way of imposing a logical consistency on monetary policy, in the presence of multiple policy objectives inflation targeting undermines policy transparency and therefore makes accountability more difficult too. Because of the limitation of monetary policy's having only one instrument, but multiple objectives, fiscal policy and prudential supervision and regulation of financial institutions are also important for enabling emerging market economies to achieve their macroeconomic aims.

The author argues that inequality, combined with only modest growth, can have grave moral consequences. History suggests that, in the past, a rising standard of living has promoted tolerance for others, commitment to economic opportunity, and democracy. But stagnating incomes due to inequality can lead to the opposite outcomes. The nation’s response to immigration is a good example, says the author.
