Data Flows Restrictiveness and (Un)equal Productivity and Jobs Effects (joint with Ana Cusolito, Erik van der Marel, and Gaurav Nayyar)
This paper presents firm-level evidence on the uneven impact of cross-border and domestic digital data restrictions—hindering personal data transfers and data processing, respectively—on revenue-based productivity (TFPR) and employment, using a new database covering 32 European countries from 2010 to 2017. Overall, the paper demonstrates that data policies neutral in design can nonetheless reshape market dynamics due to their differential impact on productivity across sectors and firms
Transitions from non-wage to wage employment are critical for poverty reduction and economic growth, yet empirical evidence on these dynamics in developing economies remains scarce. Formal wage employment offers income stability, higher productivity, and welfare gains, but labor markets in these contexts exhibit high job turnover without sustained upward mobility. This paper examines intra- and inter-cohort employment transitions, distinguishing subsistence from entrepreneurial self-employment, and evaluates their impact on income and welfare.
