The Consequences of Soil Organic Carbon for Crop Yield, Farm Productivity and Profit

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Crop choices affect soil organic carbon (SOC) stocks, allowing farmers to manipulate the amount of carbon sequestered in the soil over time. This paper examines the private and public benefits of crop rotations that sequester additional carbon across the province of Saskatchewan, Canada using a novel field‐level dataset from the Saskatchewan ...

Including Harvested Grain Biogenic CO2 to Address a Critical Flaw in Climate Accounting

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The international climate accounting system excludes both the biogenic CO2 sequestered in harvested crops and the biogenic CO2 emissions that occur when grain is digested or burned as biofuel. Despite being described in the literature as a critical flaw in climate accounting all parties within the United Nations Framework Convention on Climate

Market regulation and productivity: The case of the Canadian Wheat Board

open access: yesAmerican 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.

Harvesting benefits: Exploring the effects of second‐best policies on enhancing soil organic carbon stocks in agriculture

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Agricultural subsidies can be an effective policy tool to enhance soil organic carbon sequestration. This paper assesses the effectiveness of a second‐best hypothetical policy which subsidizes additional canola hectares optimally for each soil zone in Saskatchewan in an effort to increase soil organic carbon.
