This year’s economics Nobel Prize has gone to Oliver Hart and Bengt Holmström, for their work on the theory of contracts. It’s about incentives, and imperfect information, and long-term relationships. But it’s related to lots of real-world economic issues — performance pay, mergers and acquisitions, and bank lending.
During the past two years, we have seen signs that wage pressure is building as the economic recovery grinds on. Enough evidence has now accumulated to suggest that it is already happening.

For a few decades, economists used to imagine how the world works, write down a theory describing their idea, and call it a day.

As one old joke put it, if an idea worked in practice, economists would ask whether it worked in theory.
