“…In regional networks, these fall into three major types: economic spillover, technological spillover, and knowledge spillover (see Anandajayasekeram, Martella, and Rukuni, 1996, for a detailed discussion). Models exist to analyze economic spillover effects (Edwards and Freebairn, 1984;Davis, Oram and Ryan, 1987), but these models are data intensive. There is a need to develop simple but adequate methods and techniques that can be operationalized with available data.…”

“…These data provide a baseline against which to estimate gains that can be expected from further improving BNF as a result of research or by direct application of known technologies. With discounting for factors such as probability of success, time lags and ceiling rate of adoption, reasonable estimates can be made for costs and benefits of a suggested research and/or development effort (Davis et al, 1987(Davis et al, , 1994Edwards and Freebairn, 1984;Norton and Davis, 1981;McKenney et al, 1991).…”

IntroductionLimited adoption of inoculation technology Assessment of "need to-inoculate" Abstract Although viable Rhizobium inoculation technology for cultivated legumes has long been available, there has been little sustained adoption of this technology in tropical regions. Reasons contributing to this include inadequate demonstration of the technology, presence of adequate native rhizobia, high soil mineral nitrogen levels which suppress nitrogen fixation, inadequate quality control of Rhizobium inoculum and difficulties of inoculating under 280 tropical conditions. In order to ensure a better adoption rate of existing or emerging biological nitrogen fixation (BNF) technologies, it is proposed that future research and development efforts better focus on the researchadoption-impact continuum. The salient features of this approach are described in this paper, using the example of recently developed nodulation variants in chickpea as a potential means of increasing BNF in this crop. It is suggested that previous experience with Rhizobium inoculation technology is amenable to ex-post impact analysis to analyze bottlenecks, and that ex-ante impact analysis should be built into on-going or planned BNF research, to better ensure that technology adoption occurs.

“…More recent contributions to the literature also demonstrate that, the payoffs and distribution of payoffs from research and development (R&D) along the food value chain depend critically on the economic nature of the value chain (Freebairn et al 1982(Freebairn et al , 1983Alston and Scobie 1983;Edwards and Freebairn 1984;Holloway 1989;Alston et al 1995;Wohlgenant 1997). 1 The distribution of payoffs can shift up and down the chain depending on many economic variables.…”

The payoffs and distribution of payoffs from research and development (R&D) along the food value chain depend on many interacting economic factors. To quantify these, we have developed a general equilibrium model of the Australian economy with detailed farming, processing and marketing information. We use the model to assess potential payoffs and distributions from various R&D scenarios that lead to demand expansion and productivity improvement. We find that productivity improvement caused by R&D is unambiguously beneficial to the whole economy while the benefits of export or domestic market demand expansion mainly accrue to the primary producers and processing industry, when the economy is at full employment. Also, productivity improvement from R&D on-farm may benefit processors while improvements postfarm may benefit farmers.

The Gains from Research into Tradable Commodities

Abstract: This paper develops a model for assessing the aggregate level and distribution of the benefits of res each into tradable commodities. It estimates gains to Australia and to the rest of the world from research into the wool and wheat industries.
