The average annual wage fell fractionally last year to €35,768.
A number of sectors recorded pay rises, with construction seeing the biggest bump, rising 4.6pc to €37,884, according to the data from the Central Statistics Office (CSO).
But a separate survey from consultants Mercer shows that Dublin has moved up two places in its annual cost of living survey for expatriates, with rents driving the rise.
While Dublin is ranked behind a number of other European cities such as London and Paris (pictured), it is the only Eurozone city to move up the rankings this year, to 49th position, from 51st.
The CSO data showed that five of the 13 economic sectors recorded pay increases, but those that suffered the biggest drops were in education, and arts and entertainment, where values fell from €42,554 and €41,332 respectively, to €25,158 and €24,438.
Overall, average annual earnings last year fell to €35,768 from €35,830 in 2013, a decrease of 0.2pc, or €62.
That's an improvement on the previous year, in which earnings fell 0.7pc, or €249, between 2012 and 2013.
Those who work in the IT sector get paid the best, according to the CSO data, bringing in an annual average wage of €53,442 last year, up 0.7pc on 2013.
But those who work in the hotel and food businesses fare worse, with an annual wage of just €16,658. That's up 3.3pc on the previous year.
Sinn Fein's jobs and enterprise spokesman, Peadar Toibin, said the fall showed that "Fine Gael and Labour [are] failing to deliver a fair recovery".
