Land use regulation and productivity—land matters: evidence from a UK supermarket chain

We use store-specific data for a UK supermarket chain to estimate the impact of planning on store output. Exploiting the variation in policies between England and other UK countries, we isolate the impact of Town Centre First (TCF) policies introduced in England. We find they directly reduced output by forcing stores onto less productive sites. We estimate TCF policies imposed a loss of output of 32 percent on a representative store opening after their rigorous implementation in 1996. Additionally, we show that, household numbers constant, more restrictive local authorities have fewer stores and lower chain sales within their areas.

Accounting for Big-City Growth in Low-Paid Occupations: Immigration and/or Service-Class Consumption

Abstract The growth of “global cities” in the 1980s was supposed to have involved an occupational polarization, including the increase in low-paid service jobs. Although held to be untrue for European cities at the time, some such growth did emerge in London a decade later than first reported for New York. The question is whether there was simply a delay before London conformed to the global city model or whether another distinct cause was at work in both cases. This article proposes that the critical factor in both cases was actually an upsurge of immigration from poor countries that provided an elastic supply of cheap labor. This hypothesis and its counterpart based on the growth in elite jobs are tested econometrically for the British case with regional data spanning 1975–2008, finding some support for both effects, but with immigration from poor countries as the crucial influence in late 1990s London.

What Makes Cities More Productive? Evidence from Five OECD Countries on the Role of Urban Governance

In estimating agglomeration benefits across five OECD countries, this paper represents the first empirical analysis that contrasts cross‐country evidence on agglomeration benefits with the productivity impact of metropolitan governance structures, while taking into account the potential sorting of individuals across cities. The comparability of results in a multicountry setting is supported through the use of a new internationally harmonised definition of cities based on economic linkages rather than administrative boundaries. The analysis finds that cities with fragmented governance structures tend to have lower levels of productivity. The estimated elasticity for an increase in the number of local jurisdiction is 0.06, which is halved by the existence of a metropolitan governance body. The productivity effect is sizeable and at least as important as the agglomeration benefit found due to city size.
