tech workers in Dublin's booming FDI sector make up a disproportionate share of the jobs market because they bounce between employers far more frequently than other workers, according to a study of the relationship between online searches, employment and wages.
IT workers have higher rates of job turnover and spend 30 months less on average in roles relative to other workers.
In 2018, 7pc of Dubliners worked in the IT sector, compared with 4pc outside the capital.
Unlike traditional jobs data which tends to be "backward-looking", the so called job-search clicks give a real-time indication of the number of workers who fit a role and of the intensity of searches as well as wage growth patterns across different jobs.
"Clicks capture the degree of search for a given job or occupation," economists Reamonn Lydon and Pawel Adrjan wrote in the study by the Central Bank of Ireland and the online jobs site Indeed. "We show that clicks can explain more of the variation in salaries than regional unemployment alone," the report's authors said.
In the case of job-shifting Dubliners, that is down to the relatively high proportion of IT workers in the capital.
"Professional, Scientific and Technical Activities sector also tend to change jobs at a higher rate than average.
"Workers in this sector accounted for 7pc of Dublin employees, compared with 4pc in the rest of the country. These factors contributed to a higher rate of job switching more generally in Dublin," the economists wrote.
While many of the professions seeing demand for staff were in finance and law, there were significant shortages for registered disability nurses, senior staff nurses and registered nurses.
The Irish Nurses and Midwives Organisation's pay campaign earlier this year highlighted the difficulties of hiring and retaining qualified nurses.
