Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

Integrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Risk management externalities in agrifood supply chains

American Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

Firm turnover under asymmetric information: Tanzania's agro‐dealer sector

American Journal of Agricultural Economics, EarlyView.
Abstract We study firm turnover (i.e., entry and exit) and its consumer implications in a market characterized by asymmetric information. Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

American Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Income sharing for common pool resources with uncertain productivity

American Journal of Agricultural Economics, EarlyView.
Abstract We address the interconnected issues of externalities in the use of a natural common‐pool resource system and adverse effects of environmental uncertainty on risk‐averse resource users. We set up a simple analytical model and derive conditions such that insurance by means of an income sharing mechanism mitigates externalities and hence ...

Using pre‐ and post‐entry data to identify the effect of ethanol plant entry on the spatial pattern of corn prices: A study in Indiana

American Journal of Agricultural Economics, EarlyView.
Abstract We estimate the long‐run effect of ethanol plant entry on local corn prices using a long‐horizon difference‐in‐differences framework that combines matching with fixed effects while explicitly accounting for treatment intensity and spatial heterogeneity.
