Information framing and the impact of nutrition label serving size change

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract The framing of information can significantly influence how consumers interpret and respond to it. This paper investigates how the change in serving sizes in Nutrition Facts Panel (NFP) affects consumer choices for carbonated soft drinks (CSD). We first estimate a reduced form difference‐in‐differences (DiD) model to document causal effects on ...

Reverse auctions for drought‐responsive water buybacks: Evidence from co‐designed lab and field experiments

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Protecting endangered aquatic species while sustaining farming communities can require water buyback programs that are both cost‐effective and responsive to the variability and unpredictability of drought conditions. Working in close partnership with The Nature Conservancy and the Georgia Water Planning and Policy Center, we co‐design parallel

Buck-Boost PWM Converters Having

open access: yes, 2007
Single-switch step-up/step-down converters, such as the buck-boost, SEPIC and Cuk, have relatively high voltage and current stresses on components compared to the buck or the boost converter.

Getting (un)wasted: How planning failures generate consumer waste across resources: Time, money, goods, and energy

open access: yesConsumer Psychology Review, EarlyView.
Abstract Past research suggests that people exhibit robust waste aversion. However, many consumers routinely feel that they waste not only goods but also time, money, energy, and emotion and would be hard‐pressed to imagine their lives otherwise. Why does consumer waste persist? In this paper, we first propose a definition for consumer waste.

Utilizing robustness of positive buck-boost converter against input voltage and load current disturbances

open access: yes, 2009
A Positive Buck- Boost (PBB) converter is a known DC-DC converter that can operate in step up and step down modes. Unlike Buck, Boost, and Inverting Buck Boost converters, the inductor current of a PBB can be controlled independently of its voltage ...
