Nonparametric estimation of diffusion process: a closer look [PDF]

A Monte Carlo simulation is performed to investigate the finite sample properties of a nonparametric estimator, based on discretely sampled observations of continuous-time Ito diffusion process. Chapman and Pearson (2000) studies finite-sample properties

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.

On using nonparametric approaches for precipitation estimation

ITM Web of Conferences, 2018
Nonparametric density estimation methods have been used for precipitation estimation for decades. The new approach for estimating the density proposed recently by Geenens and Wang appears to offer advantages over them as far as their behavior in the tail

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

Applied 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 ...

Nonparametric curve estimation with bernstein estimates

Metrika, 1997
For the estimation of the regression function in a random design model a Bernstein type estimator is proposed. The author studies various local and global asymptotic properties of this estimator: Consistency and asymptotic normality at a fixed point are proved and an asymptotic expression for the expectation of the estimator is derived.

Disentangling the relationships between denomination of origin regulatory councils activities and Spanish wineries' export performance

Agribusiness, EarlyView.
Abstract World markets for quality differentiated agri‐food products are highly competitive, presenting significant challenges for firms aiming to compete effectively. Government agencies and business organizations often implement various export promotion policies to address these challenges.

Estimation of Nonparametric Conditional Moment Models With Possibly Nonsmooth Generalized Residuals [PDF]

This paper studies nonparametric estimation of conditional moment models in which the generalized residual functions can be nonsmooth in the unknown functions of endogenous variables. This is a nonparametric nonlinear instrumental variables (IV) problem.
