We again looked at those individuals moving into and out of the finance sector, but this time restricted the sample only to those doing a job with the same title in both the finance and non-finance sectors, focusing on generic job titles such as ‘function manager’, ‘ICT professional’, ‘secretarial’, ‘customer service’ etc. The results reveal that the same people doing the same job earn around 20% more when doing that job in the finance sector rather than the non-finance sector. This premium is observed to be remarkably similar whatever job title is considered – whether it is a typically high-paid or low-paid job. This suggests that the pay premium is ubiquitous across all individuals working in the finance sector. This idea is further supported by looking at the wage premium at various points of the wage distribution. Although the finance sector pay premium is observed to be the largest between high earners in the finance and non-finance sectors – at the top end of the wage distribution – it is certainly the case that it is also observed throughout the full distribution.
That is from Joanne Lindley and Steven McIntosh, there is more here. As you will grasp from basic microeconomics, this is evidence of rents and rent-sharing in the financial sector, a conclusion which the authors second.
