We find that job churn is prevalent in construction, with around 60 percent of firm-worker pairs not existing previously or not existing subsequently. The data also show that firms gaining or losing any labour are more productive than static firms, and that firms gaining labour from other construction firms are 4-6 percent more productive than the industry average in a given year. Our analysis suggests such firms are productive in part because of knowledge flows from other construction firms; in our preferred specification, with firm fixed effects, a standard deviation increase in the productivity of new employees’ previous firms is associated with a 0.6 percent increase in productivity. New entrants are more productive than pre-existing firms. Firms that enter briefly and disappear exhibit high productivity for that brief period, and firms that enter and persist exhibit a persistent productivity advantage that averages about 5%, but which grows as experience accumulates. The entry and worker-knowledge-flow phenomena are distinct, in that the entry effect is not explained by employee composition, and non-entrant firms also benefit from worker knowledge flows.
