Firm Pay Dynamics

We study the nature of firm pay dynamics using matched employer-employee data from Sweden, including rich, administrative firm financial data. To this end, we propose and estimate a statistical model that extends the seminal framework by Abowd, Kramarz, and Margolis (1999a, henceforth AKM) to flexibly account for time-varying firm pay policies. We validate our approach by showing that firm-year pay variation is systematically related to firm financial performance. Subsequently, we apply our methodology to assess the role of firm pay dynamics in accounting for a rise in earnings inequality in Sweden, to investigate the properties of the distribution of within-firm pay differences over time, to measure the degree of firm pay mobility, and to quantify the relative contribution of ex-ante versus ex-post heterogeneity towards firm pay differences over the firm life cycle. We conclude that no more than two thirds of firm pay heterogeneity are permanent, with persistent and transitory fluctuations in firm pay constituting the remainder

How to issue a privacy-preserving central bank digital currency

Many central banks are currently investigating Central Bank Digital Currency (CBDC) and possible designs. A recent survey conducted by the European Central Bank has found that both citizens and professionals consider privacy the most important feature of a CBDC. We show how a central bank could issue a CBDC that would be easily scalable and allow the preservation of a key feature of physical cash: transaction privacy. At the same time the proposed design would meet regulatory requirements and thus offer an appropriate balance between privacy and legal compliance
