There is a growing body of literature on the role of power and influence as key behavioural constructs in supply chains. In order to use power it is necessary to apply specific influence strategies which represent certain techniques to gain desired objectives. In order to manage supply chain networks successfully the knowledge of different influence strategies is essential, since they may have different managerial effects depending on their origin. The aim of our article is to investigate the role of power and influence strategies in supply chains. To fulfil our aim we conducted an empirical survey of 97 multinational companies (MNCs) that operate in the Russian agri-food sector. © Rainer Hampp Verlag. Source

Purpose-With the introduction of the mandatory European Union (EU) organic logo for all organic food products in 2010, the European Commission aimed at fostering the internal organic food market. This needs consumers’ knowledge of the logo. According to earlier research consumers’ knowledge of the EU organic logo is low. Thus, the purpose of this paper is to elicit consumers’ attitudes towards organic certification and labelling and to develop recommendations on how to improve consumers’ knowledge of the EU organic logo. Design/methodology/approach-By means of an online survey with 3,000 participants in six European countries, knowledge of the logo and attitudes towards organic farming and European labelling, as well as organic food purchase behaviour and socio-demographic indicators were elicited. Factor and cluster analysis based on several statements on the test persons’ attitudes towards organic farming and corresponding EU legislation were conducted in order to segment consumers. Findings-The results indicate that knowledge of the logo is low. Only about 15 per cent of all respondents knew its meaning. Four clusters of consumers could be identified: “Committed organics”, “Pragmatic organics”, “Organic sceptics” and Organic disinteresteds’. With reference to the EU organic legislation’s aim of promoting the organic market, particularly “Organic sceptics” should be addressed by emphasising the trustworthiness of the organic certification and labelling system. Originality/value-Segmenting consumers according to their attitude towards organic farming, its labelling and certification allows for targeted and efficient communication and organic market development. © Emerald Group Publishing Limited.

Intra-annual (within crop year) price volatility and inter-annual (between crop years) price volatility are measured for wheat, maize, rice, barley, oats and rye. A set of explanatory variables is used in a pooled regression to explain variations in these price volatilities. With low cereal stocks, supply (yield) shocks (defined here as volatilities, as for the price volatilities) mostly influence inter-annual volatility while other influential factors are the crude oil price and exchange rate. Cereal demand and interest rate shocks combined with low stocks affect intra-annual volatility, while other explanatory factors include exchange rate and crude oil price shocks. The derivatives market activity appears to have no significant effect on either intra- or inter-annual volatility. In contrast, large cereal stocks and a well-functioning international cereal market reduce the effects of shocks in the explanatory variables on both intra- and inter-annual volatilities. © 2014 The Agricultural Economics Society.

Within German agriculture, horticulture plays a small but important role. However, in the national accounts only horticultural production is considered, which builds the core of the German horticulture cluster. Hence, important parts of the horticultural value chain such as processing, trade and services are not taken into account. To get a clearer picture of the economic importance of horticulture in Germany, it is required to extend the system boundary as defined in the national accounts in order to account for upstream and downstream industries of the cluster as well. In a first step all related industries, i.e., those that either supply products to horticultural production or use horticultural products need to be identified. Thereafter the economic relevance of the horticultural cluster is quantified based on the indicators employment, output value and gross value added for each industry along the horticultural value chain. In a first step this analysis quantifies first results for directly related industries such as the chemical industry, wholesale, processing and landscaping as in a parallel study the economic relevance of horticultural production in Germany is quantified based on farm accountancy data. Indirectly related industries such as finance, retail, gastronomy or education will be investigated later to complete the analysis in a following step. Source
