This paper identifies different groups in a cost function framework of thermo energy plants belonging to EDP-Electricity of Portugal. In particular, we have clustered the sample - comprising data for years 1987 to 2006 - into two groups. To do so, we have implemented a stochastic frontier latent...

Edible insects are receiving substantial attention because of their potential as a significant future food source of high nutritional value and with important environmental benefits. As a result, there is a focus on the supply side to establish and optimize the insect production sector and...

Generalized linear models with covariate measurement error can be estimated by maximum likelihood using gllamm, a program that fits a large class of multilevel latent variable models (Rabe-Hesketh, Skrondal, and Pickles 2004). The program uses adaptive quadrature to evaluate the log likelihood,...

Given the credence nature of functional food attributes labelling plays a key role inallowing consumers to make informed choices about foods with enhanced health attributes.The degree to which a particular jurisdiction permits health claims for food products and the type of allowable health...
