Unpacking the Farmland Capitalization Effect of Ethanol Establishment

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We unpack the impact of expansions in ethanol production—as measured by proximity to newly constructed ethanol plants and capacity expansions—on farmland values using land transaction data from Kansas in combination with modern causal inference techniques.

Crop Insurance Design and On‐Farm Risk Adaptation

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The United States spends billions annually on crop insurance premium subsidies, yet the prevailing distance‐based guarantee design unintentionally rewards risk‐taking by linking subsidies to yield variability. We consider a simple redesign: define guarantees in terms of probability so that coverage reflects a consistent likelihood of indemnity.

Drivers of Precision Agriculture Adoption in Italian Viticulture

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the main drivers influencing the adoption of two types of precision farming technologies in the viticultural sector: Decision Support Systems (DSSs) and Variable Rate Technologies (VRTs). We apply a partial proportional odds model and find that socio‐demographic characteristics are not significant determinants of adoption ...

Glucosinolate and Isothiocyanate Profiles in Different Varieties of Raphanus sativus Seed via Multivariate Data Analysis

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Through HPLC–MS/MS analysis and multivariate statistics, raphani semen (RS) varieties with high functional components were screened. The white raphani semen “Xuebawang” was identified as ideal for further study due to its high bioactive content: glucoraphenin (9010.27 mg/100 g), glucoraphanin (1027.76 mg/100 g), sulforaphane (66.14 mg/100 g), and ...
