Temporary price reductions (sales) as a means of promotion have become an increasingly important tool in the marketing mix of food retailers around the world. This paper investigates the retailers' pricing strategy by explicitly accounting for the multi-product nature of retailing. We find that retailers systematically adjust the breadth and depth of sales over time and they respond aggressively to their rivals' promotional activities. Finally, the breadth and depth of sales are found to be substitutes in the set of the available strategies to increase the store traffic.

The paper presents an analysis of market power in the output milk-processing market. In particular, the paper identifies market failures in the output milk-processing market in 24 EU member states. The analysis is based on a mark-up model and the application of stochastic frontier methodology. The results show that market failures are pronounced on the EU output milk-processing market. However, the abuse of oligopoly market power is not large on average, despite the fact that we can find significant differences among the countries. The mark-up distribution is skewed toward lower values. That is, the majority of companies are characterized by only a small or almost no degree of market power; however, there are companies (about 10 %) with considerably high oligopoly market power.

The paper presents the analysis of cereal production in the EU. The analysis provides the comparison of production technologies and technical efficiency among EU countries using the country specific multiple output distance function models in the first step and metafrontier approach in the second step to determine the level and development of technical efficiency. The results show the high technical efficiency of cereal producers in the analyzed countries. On average, the differences in technical efficiency among the analyzed countries are not pronounced; however, the technologies used as well as the determinants of technical efficiency differ significantly.

Engaging relevant stakeholders in the planning process can generate better mutual understanding among participants and lead to decisions that are more sustainable. This study examines the potential for stakeholders to participate with modellers in the construction of development scenarios that can be explored through microsimulation modelling approaches. This activity requires participants, who are drawn from local administrations and the communities that they serve, to engage with the model at different stages of its development. Such engagement is important for model design and for ensuring that the resulting models are able to frame questions that the stakeholders are interested in. This study adopted a participatory workshop approach across three European countries to explore the potential for stakeholders to engage with modellers at different stages of the modelling process. The interactions between modellers and local stakeholders provided a number of important insights on the future design, conduct and application of such exercises and suggest some limits to the use of scenario development as a tool for participatory modelling and sustainable development.
