Microeconomic regulation

Everyone contributes equally to government-run pension schemes, but not everyone will spend the same number of years in retirement – blue-collar workers, for instance, do not live as long as their white-collar counterparts. Rather than pooling the resources of a heterogeneous group of workers, this column proposes that each worker receive a lump sum at a certain age, which they can then give to an occupational pension fund better informed about the life expectancy of its own participants.

The Cambridge Analytica scandal highlighted the sophisticated ways social media platforms can allow companies to infer information about users and non-users from shared data. This column shows how correlations between platform users’ and non-users’ characteristics mean companies can obtain data at below equilibrium prices, implying welfare inefficiencies for individuals. The authors make some suggestions of regulations that could improve on these data-sharing inefficiencies for users and non-users of the platforms.

Housing affordability is a leading challenge for local policymakers around the world, yet a coherent framework for analysing the various policy options is lacking. This column builds such a framework and uses it to show that policies that make affordable housing more efficient, that expand rent control, and that increase vouchers have a redistributive effect. Upzoning policies creates smaller, but more uniformly distributed benefits.

There is much debate, and nowhere more than in the US, about whether public services such as healthcare should be provided by private companies, which may offer greater efficiencies but which are more susceptible to moral hazard and adverse selection of consumers. This column uses evidence from a provision change in Texas to show that contracting healthcare provision out to private companies increased the level of care patients received, but increased overall costs for the government.

A dominant view in urban economics suggests that the solution to the housing crisis of major cities is to relax zoning and other planning regulations. This column challenges this position, arguing that there is no clear and uncontroversial evidence that housing regulation is a principal source of differences in home availability or prices across cities and that these issues are more linked to rising inequalities in the geography of employment, wages and skills. Blanket changes in zoning are unlikely to increase affordability for lower-income households in prosperous regions, but would increase gentrification without appreciably decreasing income inequality.
