The children of rich families tend to go to better quality schools, have higher cognitive skills, and complete more years of schooling. This column exploits unique data from the National Child Development study to determine these early childhood factors go on to have long-run impacts on an individual’s lifetime earnings, perpetuating a cycle of wealth. These results suggest that policies that equalise investments, such as improving school quality, could promote income mobility.

Research on economic mobility has failed to disentangle the underlying economic drivers. In particular, opportunities for upward movement represent welfare-enhancing mobility, while risky income shocks represent welfare-reducing mobility. This column presents a framework for differentiating between these factors, and applies the model to Mexican data. Results show that opportunity and risk are equally important drivers of income mobility, with large but opposing welfare effects. This challenges the idea that societies with higher measured income mobility are better.
