ABSTRACT
We evaluate the usefulness of non-representative registry data such as Orbis in drawing inferences about economic phenomena in Poland. While firm-level studies of economic phenomena are of key policy relevance, census data and representative samples are scarcely available across countries. We obtain estimates of the labour share for the period 1995–2019. For the overlapping period and samples, we compare our estimates to Growiec [2009], who drew on a census of Polish firms employing 50+ employees. We also refer to OECD STAN data. We demonstrate that time patterns are common across data sources. Additionally, we study the potential for various imputation methods to enrich inference.
