A TEST OF BAYESIAN LEARNING FROM FARMER TRIALS OF NEW WHEAT VARIETIES AgEcon
Lindner, Robert K.; Gibbs, Melissa.
In this study, elicited estimates of farmers' subjective beliefs about the mean and variance of wheat variety yields were used to test propositions about Bayesian learning developed in the recent literature on innovation adoption. A series of empirical tests of the Bayesian adoption model were conducted using beliefs elicited from farm surveys conducted in 1982, 1983 and 1984. The results of the analysis neither confirm nor reject the Bayesian approach as a model of how farmers revise subjective beliefs, but do raise serious doubts about its realism, and suggest some issues requiring further investigation. Shortcomings in the elicitation techniques are discussed and the assumptions of the Bayesian model are reviewed.

Access Issues for Plant Breeders in an Increasingly Privatized World AgEcon
Lindner, Robert K..
There is a growing trend to widespread privatisation of crop breeding, and there are grounds for expecting this trend to continue and even to accelerate. Possible consequences for Australian grain growers and the national interest of much greater private sector involvement in plant breeding are explored. Growing privatisation and commercialisation of plant breeding will lead to increased competition between plant breeders. While this increased competition has been at least partly driven by the potential for value creation, it also is likely to enhance value creation from plant breeding so long as there is adequate continuing investment in the capacity for plant breeding, and more particularly in productivity enhancing enabling technology. In the event of...

ACIAR’s 25 year investment in fruit-fly research AgEcon
Lindner, Robert K.; McLeod, Paul.
Fruit flies are recognised as one of the major pests of fruit and vegetable crops worldwide. Potential benefits from fruit fly research include biosecurity benefits from better quarantine surveillance that reduces the costs of an incursion by a damaging exotic pest fruit fly; market access benefits by enabling new fruit exports; and field control benefits from better crop management. The Australian Centre for International Agricultural Research (ACIAR)’s investment in fruitfly research goes back some 25 years to an initial project in Malaysia. Since that time, ACIAR’s continued investment has funded a total of 18 projects ranging across several areas of fruit-fly research, and covering Malaysia, Thailand, Philippines, Fiji Islands, Samoa, Tonga, Cook...

Catch allocation in a shared fishery with a minimally managed recreational sector AgEcon
Lindner, Robert K.; McLeod, Paul.
A prevalent problem in shared fisheries is competition between commercial and recreational fishers for access to a resource that is subject to increasing utilisation pressure. For most shared fisheries in New Zealand, the commercial sector is efficiently managed with a regime of individual transferable quota (ITQ), but the recreational fishing is only minimally managed. A model is developed that can be used to explore the size of the total allowable catch (TAC) that is both sustainable AND maximises the value to the NZ economy of the combined commercial and recreational catch when the commercial catch is regulated via a total allowable commercial catch (TACC) while the recreational catch (RC) is self regulating. Determinants of the optimal catch allocation...

CONSUMER PREFERENCE FOR PST-SUPPLEMENT PORK AgEcon
Halbrendt, Catherine K.; Pesek, John D., Jr.; Parsons, April; Lindner, Robert K..
Conjoint measurement was used to determine consumer preference for fresh pork produced with genetically engineered porcine somatotropin (pST). A preference model was constructed based on three pork attributes, degree of fat reduction, price, and production technology, which allowed for interactions between attributes to be estimated. Interview surveys were used to collect data in several shopping centres in three Australian cities. Respondents generally preferred leaner pST-supplemented pork, but only at fat reduction levels greater than those possible with conventionally produced pork, and at competitive prices.

DISTANCE TO INFORMATION SOURCE AND THE TIME LAG TO EARLY ADOPTION OF TRACE ELEMENT FERTILISERS AgEcon
Lindner, Robert K.; Pardey, Philip G.; Jarrett, Frank G..
Some hypotheses about the timing of farmers becoming aware of an innovation and the subsequent decision to use that innovation are derived from a recently developed, decision-theoretic model of the adoption process. They are tested using empirical evidence on the time taken by early adopters of trace element fertilisers in S.A. to discover and decide to use this innovation. The central role of information search in the adoption process is emphasised and it is postulated that various distance measures provide a useful measure of information availability and reliability. The results of the empirical analysis are consistent with the hypothesised relationships. Another finding is the importance of distinguishing between early adopters who are genuinely...

Effective information and the influence of an extension event on perceptions and adoption AgEcon
Llewellyn, Rick S.; Lindner, Robert K.; Pannell, David J.; Powles, Stephen B..
Perceptions are known to play an important role in the innovation adoption decision. Once influential perceptions have been identified, there is the potential for information to influence adoption by changing these perceptions. In this paper, the influence of an extension workshop targeting grain growers’ perceptions known to be associated with the adoption of integrated weed management and herbicide resistance management has been measured using regression analysis. Consistent with a Bayesian learning framework, the greatest influence on grower perceptions and intended adoption behaviour was observed where information could be delivered with a high degree of certainty and validity.

INVESTING IN GRAIN STORAGE FACILITIES UNDER FLUCTUATING PRODUCTION AgEcon
Brennan, Donna C.; Lindner, Robert K..
Fluctuating annual harvest volumes create a peak load problem in the provision of grain storage capacity. There are a number of technologies for handling and storing grain, ranging from capital intensive to labour intensive methods. Optimal provision of grain storage capacity can therefore be analysed in the framework of the conventional peak load pricing model. An investment model of grain storage is outlined and the optimal technology choices are determined according to simple investment roles. Capacity of the more capital intensive storage types should be only provided if the extra capital cost is justified by the saving in operating costs, which depends on the expected utilisation of storage. Some level of supply failure is justifiable. An examination...

Monitoring of compliance in Australian conservation contracts AgEcon
Crowe, Bronwyn; White, Benedict; Pannell, David J.; Lindner, Robert K..
Government and non-government conservation agencies have long-term goals and objectives to provide environmental services, such as conserving the biodiversity of Australian native vegetation. In addition to national parks and reserves, private lands are often included in conservation programs to achieve these objectives. Formal contracts are entered into between the private landholder and the conservation agency to provide environmental services, or more commonly to provide inputs that are likely to lead to environmental services. The paper examines the costs and benefits of monitoring these conservation contracts when biodiversity change is stochastic.

Out of the pot and into the money: Managing the Western Rock Lobster Fishery by ITE's or ITQ's? AgEcon
McLeod, Paul; Lindner, Robert K.; Nicholls, John.
The West Coast Rock Lobster fishery is Australia's most valuable commercial fishery. Around 550 vessels harvest an average of 10,500 tonnes of lobster per annum. The industry has an enviable track record of biological management based on a variety of input controls, although three significant pot reduction interventions have been necessary in recent years. An evaluation of a range of possible future management regimes is reported in this paper. The results were derived from a purpose built bio-economic model three separate biological zones in the fishery using non linear optimization to produce ten year steady state solutions for alternative management options. Management options included the current pot control system, and versions of variable...

Privatised provision of essential plant breeding infrastructure AgEcon
Lindner, Robert K..
As private plant breeding replaces public programs, the efficient provision and utilisation of key enabling technologies for crop breeding, which are largely knowledge based and provide the foundation for variety improvement, might be at risk. Typically, such inputs are non‐rival in use and are therefore termed essential plant breeding infrastructure (EPBI). Specific threats include the possibility of wasteful duplication in production, under‐production, under‐utilisation of produced EPBI because of price rationing, and anticompetitive outcomes in plant breeding and downstream markets. The likely level of under‐investment in hypothetical molecular‐marker technology by a profit‐maximising monopoly producer, charging uniform prices for access, is analysed...

PRIVATISING THE PRODUCTION OF KNOWLEDGE: PROMISE AND PITFALLS FOR AGRICULTURAL RESEARCH AND EXTENSION AgEcon
Lindner, Robert K..
In the absence of some form of government intervention, knowledge is a classic public good which will be under-produced because of lack of price excludability. Government intervention may take the form of establishing intellectual property rights, or other means of shielding knowledge-based innovations from imitation or copying. Such intervention offers the prospect of 'privatising' the production of knowledge in the sense that a certain level of private knowledge production may become profitable if producers can appropriate at least part of the benefits of R&D. However, publicly funded R&D or extension still can 'crowd out' private knowledge production by charging lower prices. The principal finding of this study is that such 'crowding out'...
