This paper investigates the role of social learning in the diffusion of a new agricultural technology in a developing country: Ghana. We use unique data on farmers communication patterns to define each individuals information neighborhood, the set of others from whom he might learn. Our empirical strategy is to test whether farmers change their input decisions to align with those of their neighbors who were successful in previous periods. We present evidence that farmers adopt successful neighbors practices, conditional on many potentially confounding factors including the physical proximity of plots, credit arrangements, clan membership, and soil characteristics.

The recent volatility of energy prices has numerous policy implications for agriculture. A better understanding of the factors associated with energy consumption as related to crop production management decisions and technology use may provide insight about how producers might respond to program or market incentives targeting energy use in particular, and soil and water conservation in general. Adoption of minimum tillage could reduce erosion and improved fertilizer management practices could reduce nitrogen runoff. Energy costs may be reduced with adoption of reduced tillage technology, improved drying and irrigation systems, or more careful attention to the application and timing of fertilizers.

Agricultural Science and Technology during Ming and Qing Dynasties

Chudleigh, Peter D..

An economic evaluation of two Australian Centre for International Agricultural Research (ACIAR) projects in the area of postharvest technology for tropical fruits was undertaken. This evaluation considered a 30 year time period from the first year of investment and assumed a discount rate of 5 per cent. The estimate of the net present value of the research and development investment was $93 million expressed in 1996/97 terms. The benefit–cost ratio was 38:1 and the internal rate of return estimated at 64 per cent. If benefits realised by 1996/97 were considered, the net present value was $30 million, the benefit–cost ratio was 13:1, and the internal rate of return was 63 per cent. Benefits accrued to both Thailand and Australia, with the proportion of...

This paper analyzes the sources of growth of Dutch agriculture (arable, meat, and dairy sectors). Because the time series data (1950-1997) are non-stationary and not cointegrated, it is argued that a model estimated in first differences should be used. Estimated price elasticities turn out to be very inelastic, both in the short-run and the long-run. The direct distortionary effect of price support has therefore been rather limited. However, price support has an important indirect effect by improving the sectors investment possibilities and therewith the capital stock. Public R&D expenditure mainly affected agriculture by contributing to yield improvement therewith favoring intensification of production.

Carbon capture and storage (CCS) technologies remove carbon dioxide from flue gases for storage in geologic formations or the ocean. We find that CCS is technically feasible and economically attractive within the range of carbon policies discussed domestically and internationally. Current costs are about $200 to $250 per ton of carbon, although costs are sensitive to fuel prices and other assumptions and could be reduced significantly through technical improvements. Near-term prospects favor CCS for certain industrial sources and electric power plants, with storage in depleted oil and gas reservoirs. Deep aquifers may provide an attractive longer-term storage option, whereas ocean storage poses greater technical and environmental uncertainty. Vast...

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown

Kerr, Suzi; Newell, Richard G..

The theory of environmental regulation suggests that economic instruments, such as taxes and tradable permits, create more effective technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing technological responses to a dramatic decrease in allowed pollution levels - the petroleum industry's phasedown of lead in gasoline. Using a panel of refineries from 1971 to 1995, we provide some of the first direct evidence that alternative policies affect the pattern of adoption in expected ways. Importantly, we find that the tradable permit system used during the lead phasedown provided incentives for more efficient technology adoption decisions. Where environmentally appropriate, this suggests...

Farmer Willingness to Pay for Seed-Related Information: Rice Varieties in Nigeria and Benin

Horna, J. Daniela; Smale, Melinda; von Oppen, Matthias.

A typical private good is defined by its excludability and rivalry characteristics. Information embodied in a technology might not generate rivalry among its users. By contrast, excludability is certainly a characteristic of this kind of information and its delivery can generate incentives for private participation. This study examines farmers’ preferences for seed of new rice varieties and their willingness to pay for seed-related information in villages of Nigeria and Benin. Conjoint analysis is used to estimate the structure of farmers’ preferences for rice seed given a set of alternatives. Farmers are considered to be consumers of seed as a production input, preferring one variety over another based on the utility they obtain from its attributes, which...

If a durable-good monopoly can use either of two technologies whose properties are known to consumers, the monopoly uses only the technology with the lowest average cost at low levels of production. If consumers only know about technologies in use, the monopoly may use an inferior technology initially to increase its profits, keeping the new, efficient technology secret and switching later. Thus, in either case, an inferior technology may be used; however, switching between technologies occurs only if consumers are not fully informed about both technologies.

Innovation and changes in technology have been a driving force for gains in productivity growth in U.S. agriculture. USDA's Economic Research Service has developed annual indexes of agricultural inputs, outputs, and total factor productivity (TFP) for 1948 through 2004. American agriculture relies almost entirely on productivity growth to raise output. By lowering the cost of agricultural commodities, productivity growth benefits not only farmers but also food manufacturers and consumers.

Application of a Spatial Water Model in a Chinese Watershed

Fang, Lan; Nuppenau, Ernst-August.

China's fast growing economy has brought some environmental problems, especially in water administration. Inefficiencies in irrigation activities have created severe negative effects to the environment of rural communities, and the more serious water shortages hamper food production, too. Major questions at hand are, how to improve water use efficiency, to reduce negative external effects, to optimize water allocation in agriculture, to invest in water saving technologies, and to assure more water for high value added agriculture. This paper investigates the impacts of irrigation technologies and investments in water saving on the rural economy and the environment. By taking into account individual farmers' inclination to adopt modern water-saving...

Environmental and Technology Policies for Climate Change and Renewable Energy

Fischer, Carolyn; Newell, Richard G..

We assess different policies for reducing carbon dioxide (CO2) emissions and promoting the innovation and diffusion of CO2-reducing power technologies: (1) emissions price, (2) tax on fossil power, (3) tradable emissions performance standard, (4) market share requirement for renewables, (5) renewables production subsidy, and (6) R&D subsidy for renewables. We evaluate the relative performance of the policies according to incentives they provide along different avenues for emissions reduction, their efficiency, and other salient outcomes. We also assess how the nature of technological progress-whether it occurs by learning by doing or R&D investment and the degree of knowledge spillovers -affects the desirability of different policies.

Food can be produced under a number of technological conditions. Some observers hold that modern crop production technologies, typified by those embodied in the Green Revolution, are so intensive in the use of external inputs that they damage the environment and so are not sustainable. Those observers argue that "alternative" technologies that use fewer, safer external inputs mark the path toward agricultural sustainability. But the question arises: will those alternative technologies permit increases in global food production on the required scale? In this paper, we address this question and the conflicting arguments regarding the answer.
