Agri-food organizations that are capable of “sensing the market” – that is,capable of searching,processing and using market information,are usually also market oriented,innovative, entrepreneurial and successful. But how can a small farm with limited resources develop market sensing capabilities? This research explores when public Research & Development (R&D) has an impact on small farms’ market sensing capabilities. The literature on the impact of public R&D on small farms’ market orientation is limited despite the importance of the topic for regional competitiveness and economic development. This research follows an inductive “grounded theory” approach of investigation. Qualitative and quantitative data is collected from five cases of public-private R&D projects funded by the Australian Seafood Cooperative Research Centre (CRC). One “typical” in-depth case study of an R&D project in the oyster sector provide empirical evidence for cross-case comparison and structural equation modeling (SEM). Findings highlight the provision of R&D market information on estimated prices and quantities,end users’ lower initial capabilities and higher discipline clarity,and the absence of industry associations undertaking marketing roles for farmers to enhance the impact of public R&D on small farmers’ market sensing.
