Good and Bad International Commitments

On his blog, Dani Rodrik argues that

the fact that an international rule is negotiated and accepted by a democratically elected government does not inherently make that rule democratically legitimate.

Rodrik distinguishes two types of international commitments. On the one hand, there are commitments that help to overcome time-inconsistency problems.

[For example, the government] would like to commit to free trade or to fiscal balance, but realizes that over time it will give in to pressure and deviate from what is its optimal policy ex ante. So it chooses to tie its hands through external discipline. This way, when protectionists and big spenders show up at its door, the government says: “sorry, the WTO or the IMF will not let me do it.” Everyone is better off, save for the lobbyists and special interests. This is the good kind of delegation and external discipline.

On the other hand, there are commitments that mainly serve to tie the hands of current or future political opponents.

From an ex-ante welfare standpoint, this strategy has much less to recommend itself. The future government may have better or worse ideas about government policy, and it is not clear that restricting its policy space is a win-win outcome. This kind of external discipline has much less democratic legitimacy because, once again, it privileges one set of interests against others.

In an earlier contribution, I have argued that a key role of the European Union should be to play the former role.

  • The US fiscal system underwent a radical transformation around the time of the Great Depression.
  • Perceived cost differences of revenue collection across levels of government, due to general equilibrium effects, can partly explain the rise of tax centralization and intergovernmental grants.
  • We develop a micro-founded general equilibrium model that blends politics and macroeconomics. (See the working paper.)

Science and the Senate

The Economist’s Graphic Detail reports about research documenting that

While the Senate’s interest in science is generally quite low, Senate Democrats are three times more likely than Republicans to follow science-related Twitter accounts like NASA or the National Oceanic and Atmospheric Administration. Interest in science, the authors conclude, “may now primarily be a ‘Democrat’ value”.
