Linked employer-employee data offer a wide range of possibilities for researchers. For example, this type of data is used to understand the role of worker and firm quality in the development of wage inequality, as for example in Card, Heining, Kline (2013). A widely used approach to identify worker and firm quality was developed by Abowd, Kramarz and Margolis (1999) who decomposed earnings in a worker-specific component, a firm-specific component and an error term in a two-way fixed effects model. Since then, many researchers have used the AKM model to study worker and firm heterogeneity in wages, as well as the importance of labour market sorting. While the model continues to be heavily used until today, recent developments discuss potential biases and propose corrections (for example Abowd et al, 2004; Andrews et al, 2008, 2012; Kline, Saggio, Sølvsten 2020; Bonhomme et al, 2023). The purpose of this workshop is to bring together researchers working with these models to present and discuss current work. Possible topics for the workshop are:
- How important are worker and firm heterogeneity for the variation of wages?
- How do wage premia differ for worker subgroups?
- How persistent are wage premia?
- How important is worker-firm sorting?
- Is there assortative matching in the labour market?
- Are there persistent penalties to working in low-quality firms?
