Online Research Panel

The Online Research Panel (PEO) is an online management recruitment system that allows conducting online and in-person studies in the fields of Economics and Management. PEO is under the responsibility of Center for Applied Studies (CEA) of CATÓLICA-LISBON, providing support on applied projects.

Currently, PEO has the support of faculty and research members of CATÓLICA-LISBON, which constitute a multidisciplinary, international, and highly professional team. This team allows the development of customized solutions, using different methodologies both in terms of qualitative studies and quantitative studies, having the ability to meet specific needs of public, private and social institutions.

PEO also collaborates with the Laboratory of Experimental Research iN Economics and Management (LERNE), which provides a research lab with individual working stations, as well as a retail lab, allowing the collection of in-store data, expanding the field of study and of data collection of PEO.

One of the main objectives of PEO is to maintain a panel of participants with different characteristics, allowing the definition of specific and generic samples in order to respond accurately to the objectives of the studies requested by researchers or companies. PEO uses varied strategies to recruit participants, and ensures that participants’ data are updated on a regular basis.

Currently, the panel has approximately 15.700 registered participants, aged between 17 and 77 years old. Participants live in different districts of Portugal, with 30% living in Lisbon, 14% in Oporto, 6% in the autonomous regions of Madeira and Azores, and 50% distributed by the remaining districts.

PEO provides a unique research tool to collect data from a heterogeneous and highly diversified panel.
