The paper presents the synthetic results of research on the evaluation of efficiency of selected food industries in Poland, in the years 2000-2013. A dynamic approach was applied to the studies which were based on the analysis of prices of raw materials, meat products and product assortments of...

We consider a situation where the relatively ‘poor’ are concerned about their relative income status with respect to a relevant reference group. Such a concern is explicitly introduced in a utility function to study the consumption and saving behavior of the poor in terms of a static and...
