Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver.

A characterization of matroidal systems of inequalities
Discrete Mathematics, 1988 We consider the polyhedron \(Conv\{x\in \{0,1\}^ n: Mx\leq b\}\), where M is a \(p\times n\) matrix of zeroes and ones and b is a nonnegative integer vector. We give a characterization of such polyhedra whose extreme points are the incidence vectors of the family of independent sets of a matroid and extend our result to polyhedra which are the convex ...

Why Didn't I Get a Payout? Understanding Farmer Choices, Index Insurance, and Basis Risk
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Index insurance, while heralded as a potential solution to alleviate poverty and food insecurity among agricultural households, has its own set of challenges, notably basis risk. Basis risk is the discrepancy between the insurance payout and losses incurred, posing a significant deterrent to the adoption of index insurance.

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 ...
