Understanding Egg Price Volatility and Policy Implications in the U.S. With Machine Learning
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Eggs are an inexpensive and sustainable source of proteins, but volatility in the U.S. egg prices has intensified in recent years, raising concerns over food affordability and market stability. This study examines the drivers of U.S. egg price dynamics over 2004–2025 using a two‐stage framework that combines LASSO‐based variable selection with

IFAC-PapersOnLine, 2017 Abstract In this paper, it is shown that neither Riemann-Liouville’s nor Caputo’s definitions can be used to properly take into account initial conditions in the description of a fractional partial differential equation. This demonstration is done on a counterexample. Some suggestions are made to address this problem.

Noise and Music Together. Soundscapes of Seventeenth- and Eighteenth-Century Rome
, 2023 This chapter investigates the key elements of Rome’s soundscapes in the seventeenth and eighteenth centuries from a diachronic perspective through an analysis of various typologies of sounds, from the ‘keynote’ and ‘low definition’ sounds of ...

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 ...

Are all meats substitutes? A basket‐and‐expenditure‐based approach
Agribusiness, EarlyView.Abstract This study examines the relationship among animal‐based meat and plant‐based meat alternatives (PBMAs) using a basket‐and‐expenditure‐based choice experiment. In particular, we examine whether animal‐based meat products are substitutes or complements with PBMAs.

Proportional Caputo Fractional Differential Inclusions in Banach Spaces
, 2022 In this work, we introduce the notion of a (weak) proportional Caputo fractional derivative of order α∈(0,1) for a continuous (locally integrable) function u:[0,∞)→E, where E is a complex Banach space.

U.S. Consumer Preferences for Cage‐Free Eggs and Hen Housing Policies
Agribusiness, EarlyView.ABSTRACT Farm animal welfare (FAW) continues to be a divisive issue in the egg industry. In the United States, 10 states and most major retailers have implemented policies or voluntary pledges to transition to 100% cage‐free egg sales. We use best‐worst scaling and discrete choice experiments to evaluate U.S.

Analysis of JS-contractions with applications to fractional boundary value problems
Journal of Inequalities and Applications, 2023 In this article, we modify JS-contractions by weakening the conditions on the function θ, where θ : ( 0 , ∞ ) → ( 1 , ∞ ) $\theta : ( 0,\infty ) \rightarrow ( 1,\infty ) $ is a strictly increasing function.
