Productivity Growth and Workers' Job Transitions: Evidence from Census Microdata

We use administrative data for Chile to provide novel insights on the relationship between job transitions and productivity differentials and quantify how different groups contribute to aggregate reallocation. While on average workers move to more productive firms, almost half of transitions are 'down the productivity ladder'. Reallocation gains are mostly explained by a narrow subset of transitions: young, high-skilled workers generate the lion's share of aggregate productivity gains. Workers with high turnover contribute proportionally the least. Therefore, while job reallocation yields a net benefit, it hides massive and heterogeneous gross flows, with many appearing to add little to aggregate efficiency.
