International Marketing Reviewin two cross-border value chains also appear in the mental models of decision makers at two levels of these value chains.Design: The laddering method elicits mental models of actors in two value chains: Norwegian salmon exported to Japan and Danish pork exported to Japan. The analysis of the mental models centers on potential overlap and linkages between actors in the value chain, including elements in the mental models that may relate to the actors' market orientation. Originality: This article offers three novel ideas: using the concept of mental models as a possible mediator between factors that influence the degree of market orientation and marketoriented activity; using a laddering method to elicit mental models; and considering concepts shared among actors in a value chain as possible indicators of the degree of market orientation. Market orientation, commonly defined as the generation of market intelligence, its dissemination within the business organization, and its use to direct business activities (Kohli and Jaworski, 1990), can drive superior company performance in various contexts and industries (Cano et al., 2004), including exporting manufacturers (Cadogan et al., 2003;Racela et al., 2007). Research on market orientation also investigates external factors that may influence the degree of marketoriented activities undertaken by an organization, including competitive pressures, market growth, and the heterogeneity of customers served (e.g., Avlonitis and Gounaris, 1999;Cadogan et al., 2003;Grunert et al., 2005;Jaworski and Kohli, 1993;Slater and Narver, 1994). But what is the mechanism by which such factors work? They must influence managerial decision making that selects market-oriented activities as salient courses of action.Mental models might provide a means to analyze the extent to which manager's view customer-related or environmental factors as determinants of competitive advantage (Day and Nedungadi, 1994). This research extends such reasoning to external factors that may affect the degree of market orientation through their impact on decision makers. That is, when decision makers perceive market-oriented factors as decisive for the success of their business, they engage in market-oriented activity. Therefore, we consider the link between the organizational construct of market orientation and individual-level market-oriented cognitions, similar to recent contributions regarding individual-level market orientations (Celuch et al., 2000;Schlosser and McNaughton, 2007), the role of national culture in affecting the link between organizational factors and market orientation (Kirca and Hult, in press), and the global adoption of the marketing concept (Nakata, 2000). We also consider recent work in institutional theory that deals with environmental pressures and their appearance in managers' mental models (Daniels et al., 2002). 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 ...
