This study examines the determinants of total factor productivity (TFP) in US firms. Moreover, the firms' technology diversification and its effects on TFP is explored. This study uses the US Compustat database during the period 1976-2009. The overall results indicate that both firm and industry...

Why do cities differ so much in productivity? We document that most of the measured dispersion in productivity across US cities is spurious and reflects granularity bias: idiosyncratic heterogeneity in plant-level productivity and size, combined with finite plant counts. As a result, economies...

We study the behaviour of Canadian total factor productivity growth over the past 60 years. We find that the observed stagnation during the last 20 years is entirely accounted for by the Oil sector. Higher oil prices made capital-intensive sources of oil like the oil sands viable to extract on a...

We study potential impacts of future climate change on U.S. agricultural productivity using county‐level yield and weather data from 1950 to 2015. To account for adaptation of production to different weather conditions, it is crucial to allow for both spatial and temporal variation in the...
