Abstract:	This thesis studies the interaction of recent productivity dynamics and their various drivers with other economic outcomes, in particular related to the labour market. Chapter 1 exploits harmonised and comparable data for 13 OECD countries from the MultiProd database to shed new light on the relationship between productivity divergence, i.e. increasing gaps between the most and least productive firms in an industry, and aggregate productivity growth (APG). Chapter 2 again builds on the MultiProd database to comprehensively analyse the productivity-employment nexus at different levels of aggregation. The evidence suggests that both micro- and industry-level productivity growth translate positively into employment growth on average, which however is the outcome of counteracting mechanisms and the quantitative extent of the positive link depends on firm and industry characteristics. In Chapter 3, I theoretically investigate the previously neglected role of workers as task-aggregating institutions for the impact of automation technologies on labour demand. The analysis rationalises the positive micro-level relationship of automation on labour demand that prevails despite the task-replacing nature of automation. At the same time, automation may reduce employment at the more aggregate level and contribute to the fall of the labour share.
