We had great opportunity to show our preliminary work on labour share in Poland at the (Ce)^2 Workshop 2022 poster session. The (Ce)² workshop was co-organised by Centre for Economic Analysis (CenEA, Poland) and the Centre for Microdata Methods and Practice (CeMMAP, UK). We are immensely grateful for valuable comments that broadened our way of thinking about the problem and suggested a few interesting extensions to our current work.

Firm level micro data allows researchers to dive deep in explaining the dynamics of labour share. Financial firm-level data about Poland provided by Central Statistical Office (CSO) is available only for a minor group of economists. Our study aim at providing to wider audience Orbis database, that is rich in financial statement information about substantial part of Polish firms. Using the data we present the evolution of labour share of value added in Poland, together with labour productivity and wages. We compare our estimates with Growiec (2009) and national accounts data. We find that different data source produce differing levels of indicators, however its shapes remain similar. Furthermore we show how to construct database using Orbis data and how to improve its coverage using imputation methods.
