350. HANK or RANK – how monetary policy works, or doesn’t

10th May, 2023 New Keynesian economists have accepted that their HANK model, which models the behaviour of one representative agent, doesn’t explain the outcomes on different income groups. As we know, the latest rate rises are having a more profound impact on income variation. Steve says their models don’t work because they don’t realise the distribution of income. The answer , according to the new Keynsians, is to assume a HANK model, which allows for heterogeneity, with different consumer groups behaving in different way, dependent on their income and wealth. Is this a step forward, or a band aid on a flawed concept?
