Modern macro models offer insights into the outcomes of adopting entire policy regimes, but in reality, policymakers are rarely required to make such broad-ranging policy decisions. This column suggests how theoretical and applied microeconomics can be used to develop a framework for modern macroeconomic policymaking, and demonstrates how game-theoretic principles could be used to make series of sequential policy decisions. While this approach requires large amounts of data, it would allow academic macroeconomists to refocus on important policy questions.

Evidence shows that individuals often do not act in a completely selfish manner, but rather take into account the welfare of other parties when making decisions. But how decision-makers trade off costs and benefits when the costs are dispersed among many individuals is unclear. This column discusses new experimental evidence showing that a large fraction of individuals are ‘insensitive to group size’, attaching similar weights to small and large groups. These findings provide a new explanation for a number of empirical patterns, including political and medical decision-making, lobbying, tax evasion, and charity donations.

Japan is under new leadership, bringing fresh attempts to tackle deflation. This column argues that the lessons we can learn are Going forward, a change of party politics with every change of government will likely become a recurring event in Japan. In order to restore people’s confidence in the fiscal management and social security system in the light of that prospect, institutional systems should be designed in a way to allow flexibility, premised on the fact that the government cannot make commitments into the remote future. Political leaders – whether they belong to the ruling or opposition parties – need to come up with new ideas toward achieving that end.

Central banks are increasingly transparent but is the spotlight is stifling? Analysis of FOMC transcripts before and after Committee members knew that they would be published shows how transparency deadened the debate and reduced the number of challenges to Greenspan’s position.
