Do note the latter aspect of the final sentence, but the whole thesis is exciting:
This paper utilises a one of a kind, objective-constructed panel dataset on prominent authors in the UK and Ireland born 1700–1925 to estimate the productivity gains related with agglomeration of an market with handful of capital specifications and no apparent want to cluster geographically. I uncover the typical author experiences productivity gains of 11.94% per annum when residing in London, the only big literary cluster – a acquire not related with living in any of the minor literary clusters. I uncover proof of damaging choice with respect to productivity, indicating the benefits are not driven by the self-choice of hugely productive authors to London. I uncover heterogeneity of returns to living in London by birth cohort and Effect Index quartile (a measure of author good quality) and that the cohorts who get the greatest gains from locating in London are these for which there is the strongest proof of damaging choice with respect to productivity.
