The Great Migration is associated with increased residential segregation in northern cities, inflating rents and eroding housing values. This column uses new data at the block level to estimate the scale of price changes. Segregation and ghetto expansion meant that much of the gain in earnings for black families who moved north were cancelled out. The effects of this are still felt today.

Good architectural design is a public good, but economists and policymakers lack robust evidence on the impact of well designed architecture on location value when planning spaces. This column verifies the worth of preserving and designing good architectural spaces by analysing the changes in property prices across conservation and non-conservation areas in England. It finds that good design in buildings has a substantial positive impact on location value.

While some of the costs of climate change won’t be incurred for centuries, the actions to mitigate them need to be taken today. Over such a long timespan, small changes in discount rates can drastically change the attractiveness of such investments. This column presents estimates of appropriate discount rates for very long time horizons. The long-run discount rate for one important risky asset class – real estate – is estimated at 2.6%. This provides an upper bound on long-run discount rates for climate change abatement, one that is substantially lower than some of the rates currently being employed.
