How Video‐Based Information Affects Farmers' Willingness to Pay for Drone Services

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Professional service for digital technology like agricultural drones lowers transaction costs and scope thresholds for smallholders. Meanwhile, perceptual adoption barriers remain underexplored. We conduct a two‐stage choice experiment with a randomized video‐based information treatment among 384 Chinese crop farmers to measure its effect on ...

Do Universal Free School Meals Improve the Dietary Quality of Food‐At‐Home Purchases?

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Since 2014, the number of schools offering universal free meals to all enrolled children without requiring annual meal applications has increased meaningfully. Using USDA's Purchase to Plate Crosswalk, a difference‐in‐differences framework, and a nationwide consumer panel, the effect of universal‐free‐meal exposure on the diet quality of food ...

On robust nonparametric regression estimation for a functional regressor

open access: yesStatistics & Probability Letters, 2008
We study a family of robust nonparametric estimators for a regression function based on a kernel method when theregressors are functional random variables. We establish the almost complete convergence rate of these estimatorsunder the probability measure’s concentration property on small balls of of the functional variable. Simulations aregiven to show
