Efficiency of Milk Processing Companies – Parametric and non-Parametric Approaches
In the paper, the authors considered estimation of efficiency, which measures the ability of a company to obtain the maximum output from given inputs. The comparison of results obtained by using two approaches: parametric (on the example of the SFA method, Stochastic Frontier Analysis) and non-parametric (on the example of the DEA method, Data Envelopment Analysis) has been carried out. Data from the companies of a key food processing sector in Poland, namely the milk...
Shelf life extension and food waste reduction
Pegah Amani & Lars-Erik Gadde
Waste is a significant problem in food supply chains. There is potential for spoilage of food products at any stage of the supply chain when the products reach their “best before” or “salable date”. As a key to the food waste problem, there is a trend towards developing shelf life extension solutions that are intended to allow products not only to last longer but also to improve their quality and nutritional benefits. The objective of...
Analyzing Food Supply and Distribution Systems using complex systems methodologies
Vanessa Armendàriz, Stefano Armenia, Alberto Stanislao Atzori & Angelo Romano
This paper discusses how a complex-systems perspective can shed light on the analysis of complex food-systems meeting urban food needs. The common features between complex systems and Food Supply and Distribution Systems (FSDS) are explored. A brief review of the major approaches - agent-based models (ABM), social network analysis (SNA), and system dynamics (SD) - is developed in order to make an assessment on the analysis performance of different complex system methodologies while dealing with...
Price Transmission in Vertical Dairy Chains: The Italian Case
R. D. Weaver, F. Rosa & M. Vasciaveo
At a theoretic level, price transmission does not provide a clear signal of competitiveness as many conditions may induce stickiness and even asymmetry in the speed of adjustment to positive and negative changes. While evidence from past EU studies for the dairy sector is mixed, several studies have found evidence of asymmetry in particular countries. However, none to our knowledge have considered evidence for Italy. We examine price dynamics within the chain and test for...
Birgit Schulze‐Ehlers
This paper shows how job search success, measured as search duration and entry salary, is affected directly or indirectly by personal and process as well as structural characteristics. A specific focus is on the relevance of practical experience which is claimed to be a key feature of employability. While self‐assessed practical and namely international experience is positively related to salary, but not to search duration, the number and duration of internships does not affect job...
Integration of the Food Supply Chain as a Factor of Sustainable Development
Agnieszka Bezat-Jarzębowska & Sebastian Jarzębowski
The aim adopted in the paper was to lead the scientific reasoning on sustainable development in context of economic entities and its integration in the supply chain. It is to be noticed that integration of supply chain is one of the factor for using or limiting the functional weaknesses of the market which are related to the three sustainability aspects as environmental, social and economic resources, as assumes the concept of sustainability. In the paper,...
