March 2018Worker Flows, Entry and Productivity in the New Zealand Construction Industry
with Nathan Chappell, Adam B. Jaffe: w24376
The 21st century global decline in productivity growth is not well understood. One possible contributor is a decline in economic dynamism. We explore the contribution of firm formation and employee movement to productivity using administrative data on the population of New Zealand construction firms from 2001-2012, along with linked data on their employees and working proprietors, to study the relationships among entry, worker flows and firm productivity. Entrants are more productive than pre-existing firms. Firms that enter and stay exhibit a persistent productivity advantage that averages about seven percent, but which grows as experience accumulates. We find that job churn is prevalent in construction, with around 60 percent of firm-worker pairs not existing previously or not existing s...
August 2015The Impact of R&D Subsidy on Innovation: a Study of New Zealand Firms
with Adam B. Jaffe: w21479
This paper examines the impact of government assistance through R&D grants on innovation output for firms in New Zealand. Using a large database that links administrative and tax data with survey data, we are able to control for large number of firm characteristics and thus minimise selection bias. We find that receipt of an R&D grant significantly increases the probability that a firm in the manufacturing and service sectors applies for a patent during 2005–2009, but no positive impact is found on the probability of applying for a trademark. Using only firms that participated in the Business Operation Survey, we find that receiving a grant almost doubles the probability that a firm introduces new goods and services to the world while its effects on process innovation and any product innov...
