Market regulation and productivity: The case of the Canadian Wheat Board
American Journal of Agricultural Economics, EarlyView.Abstract Changes to regulatory environments influence firm‐level incentives, which can move the productivity frontier or reposition firms within an existing frontier. Estimating causal effects of policy changes requires a credible counterfactual for productivity in the absence of policy change.

Environmentally adjusted productivity growth and shadow prices for dairy farms
Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.
