„We inve­sti­ga­te three alter­na­ti­ve but com­ple­men­ta­ry indi­ca­tors of mar­ket power on one of the lar­gest onli­ne labo­ur mar­kets (OLMs) in Euro­pe: (1) the ela­sti­ci­ty of labo­ur demand, (2) the ela­sti­ci­ty of labo­ur sup­ply, and (3) the con­cen­tra­tion of mar­ket sha­res on the OLM under stu­dy. We explo­re how the­se indi­ca­tors rela­te to an exo­ge­no­us chan­ge in plat­form poli­cy. In the mid­dle of the obse­rva­tion period, the plat­form made it man­da­to­ry for employ­ers to signal the rates they were wil­ling to pay as given by the level of expe­rien­ce requ­ired to per­form a pro­ject, i.e., entry, inter­me­dia­te or expert level. We find a posi­ti­ve labo­ur sup­ply ela­sti­ci­ty ran­ging betwe­en 0.06 and 0.15, which is higher for expert-level pro­jects. We also find that the labo­ur demand ela­sti­ci­ty incre­ased whi­le the labo­ur sup­ply ela­sti­ci­ty decre­ased after the poli­cy chan­ge. Based on this, we argue that mar­ket-desi­gning plat­form pro­vi­ders can influ­en­ce the labo­ur demand and sup­ply ela­sti­ci­ties on OLMs with cor­re­spon­ding recru­it­ment poli­cies. We also explo­re the demand for and sup­ply of AI-rela­ted labo­ur on the OLM under stu­dy. We pro­vi­de evi­den­ce for a signi­fi­can­tly higher demand for AI-rela­ted labo­ur (ran­ging from +1.3% to +4.1%) and a signi­fi­can­tly lower sup­ply of AI-rela­ted labo­ur (ran­ging from ‑6.8% to ‑1.6%) than for other types of labo­ur. We also find that wor­kers on AI pro­jects rece­ive 3.0%-3.2% higher wages than wor­kers on non-AI projects”.

A series of Polish-language meetings during which researchers and guest speakers look at issues related to digital transformation, new technologies, innovation and digital research methods.

The aim of the "Digitisation under the closer look of science" seminars is to build cooperation between academia, the public sector and business. Scientists share their research findings and have the opportunity to discuss them with experts. The results of their work are available on the DELab UW website.
