The North American Productivity Workshop (NAPW) is a major biennial conference on the topics of productivity, efficiency and performance analysis. We expect a very large number of participants to attend, from a wide international community. Presentations are invited on the theory and application of economics, econometrics, statistics, management science and operational research to various problems in the areas of productivity and efficiency. All popular techniques and methodologies will be represented, including stochastic frontier analysis, data envelopment analysis, bootstrapping approaches, and many more. We also welcome papers on broader issues related to measuring, understanding, incentivising and improving the productivity and performance of firms, public services and industries.
