Risk management externalities in agrifood supply chains

open access: yesAmerican 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 ...

Premium subsidy designs and crowding out of insurance demand

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is an important instrument to protect farmers against extreme weather events. Many countries provide subsidies for crop insurance products to make insurance more affordable for farmers. The Federal Crop Insurance Program in the United States and major European crop insurance programs such as in Spain, Italy, and France focus on ...

Information framing and the impact of nutrition label serving size change

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract The framing of information can significantly influence how consumers interpret and respond to it. This paper investigates how the change in serving sizes in Nutrition Facts Panel (NFP) affects consumer choices for carbonated soft drinks (CSD). We first estimate a reduced form difference‐in‐differences (DiD) model to document causal effects on ...

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

open access: yesAngewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Floral traits and hermaphrodite abundance shape female advantage in a gynodioecious plant

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Gynodioecy is maintained through female advantage in seed fitness that depends on the sex ratio of a population. We hypothesized that females of Silene acaulis would exhibit floral traits associated with elevated outcross pollination and that sex ratio would impact pollen limitation and inbreeding depression such that female advantage ...
