Consumers' valuation for cultured meat: A multi‐city choice experiment in China

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Despite the rising interest in cultured meat, there remains scant information on whether consumers would value it. This study evaluated consumers' willingness‐to‐pay (WTP) for cultured chicken and examined how information affects WTP. Using a choice experiment with a total of 571 samples, the results found that consumers are unwilling to pay a

On Modelling Insurance Data by Using a Generalized Lognormal Distribution || Sobre la modelización de datos de seguros usando una distribución lognormal generalizada [PDF]

Revista de Métodos Cuantitativos para la Economía y la Empresa, 2014
In this paper, a new heavy-tailed distribution is used to model data with a strong right tail, as often occurs in practical situations. The distribution proposed is derived from the lognormal distribution, by using the Marshall and Olkin procedure.

Inference with the lognormal distribution [PDF]

Several estimators of the expectation, median and mode of the lognormal distribution are derived. They aim to be approximately unbiased, efficient, or have a minimax property in the class of estimators we introduce.

Managing water resources and aquatic invaders: Public preferences, stakeholder perspectives, and policy implications

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Aquatic invasive species threaten water resources by reducing biodiversity, disrupting ecosystems, and impeding recreation. Managing these invaders is challenging due to public concerns over chemical control methods and conflicting stakeholder preferences.

Species traits shape the relationship between local and regional species abundance distributions

Ecosphere, 2019
The species abundance distribution (SAD) depicts the relative abundance of species within a community, which is a key concept in ecology. Here, we test whether SADs are more likely to either follow a lognormal‐like or follow a logseries‐like distribution

Essential and toxic elements intake from botanical extracts: a probabilistic risk–benefit evaluation within the Italian dietary context

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Botanical extracts are widely consumed for their claimed health benefits, yet their safety profile with respect to chronic consumption remains poorly characterized. Understanding the potential health risks associated with their inorganic content is a crucial issue for ensuring safe use, along with a characterization of the ...

Finding Most Reliable Path With Extended Shifted Lognormal Distribution

IEEE Access, 2018
Travel time uncertainty may cause late arrival and impose a high penalty on travelers. There is a growing interest in modeling travel time uncertainty to optimize the reliability of travel time at the path and network level. Real data analysis finds that
