The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other methodological possibilities, whose application to the valuation of this type of project may prove to be of interest. It is the case of the Contingent Valuation Method used for the evaluation of the effects of the Watershead Restoration and Erosion Control Projects of the Aljibe Basin (Almería) Spain, presented here. The results obtained show that, in this case study, application of Contingent Valuation ascribes greater social profitability of the project, with 5.23 % of IRR (Internal Rate of Return), compared to the value obtained using classic methodology of 2.25%, thus enabling us to draw closer to the true socio-environmental value of this type of project. In any case, both possibilities rather than alternatives can be considered as complementary, by focusing on the valuation from different perspectives.

By means of the transaction cost theory, the study identifies the motives for vertical integration or coordination in the Russian agro-food sector and assesses the forms of vertical integration developed so far. One can distinguish between state-initiated integration forms and such initiated by the economic agents themselves. Whereas the aim of the former is to dilute assumed market power of the food industry, uncertainty about market partners regarding reliable supply and marketing conditions and especially the fulfillment of payment obligation is the main motive for the latter. Often the chosen forms of vertical integration or cooperation not only comprise enterprises of the whole marketing chain, but also of a whole region. This could create problems with regard to competition, since barriers to entry could be raised substantially and collusion among economic agents facilitated.

This paper considers vertical price relationships between wholesalers and retailers on five local maize markets in Benin. We show that if the common factor and the long-run disequilibrium error are not explicitly taken into account in testing the channel model, one can easily be wrong about how restrictions on the error-correction structure must be interpreted in terms of economic power in the channel. The empirical results show interesting differences between markets and reveal that retailers play a more prominent role in the price formation process than generally assumed in the literature. Retailers in the two major towns do not allow wholesalers to behave as vertical price leaders, but in the two larger rural centers, wholesalers involved in arbitrage among urban markets are able to influence price formation.

Voluntary environmental agreements have been popular with government agencies in several countries. However, many questions remain about their efficiency as a regulatory tool. Recent analyses suggest that they are more effective than conventional regulatory or economic approaches when dealing with diffuse pollution and when innovation processes at the source are necessary to define effective regulation. This paper applies an activity-based framework to assess the contribution of such a voluntary agreement to the environmental performance of farms participating in a whole farm plan in the Southern part of Belgium. Using a cross-section of 52 farms, our results show that farms entering into environmental agreements are environmentally more efficient than non-participating farms in terms of the preservation and provision of landscape features. However, their environmental efficiency with regard to the reduction of non-desirable outputs, such as organic nitrogen, is mostly determined by technical efficiency and not by participation in the whole farm plan.
