A diffusion model for the adoption of agricultural innovations in structured adopting populations AgEcon
McRoberts, Neil; Franke, A.C..
We introduce a new model for examining the dynamics of uptake of technological innovations in agricultural systems, using the adoption of zero-till wheat in the rice-wheat system in Haryana state, India, as a case study. A new equation is derived which describes the dynamics of adoption over time and takes into account the effect of aggregation (e.g. on a spatial and/or cultural basis) in the adopting population on the rate of adoption. The model extends previous phenomenological models by removing the assumption of homogeneity in the non-adopting fraction of the population. We show how factors affecting the per capita rate of adoption can be captured using cognitive mapping and simulate the dynamics of the adoption process.

Riva, Fabiana Rodrigues; Costa, Patricia Ferreira; Cordeiro, Higor.
As informações se restringem cada vez mais em poder de menos pessoas ocasionando uma disparidade na utilização das praticas administrativas. O setor agrícola constantemente tem sofrido com esta situação, pois os micros e pequenos empresários dificilmente conseguem acompanhar tais mudanças e o nível de competitividade destes diminui ocasionando baixa produtividade e perdas na qualidade dos produtos, prejudicando os processos de aprendizagem, cooperação e inovação e consequentemente o desenvolvimento deste APL. Buscando identificar como ocorrem esses processos e conhecer sua importância para os atores de um arranjo foi realizado um levantamento de suas interações nos diversos segmentos do arranjo produtivo local do agronegócio leite no município de Jaru em...

A KUTATÁSI EREDMÉNYEK SORSA ÉS HASZNA AgEcon
Szucs, Istvan; Jarasi, Eva Zsuzsanna; Erdeine Kesmarki-Gally, Szilvia.
The economic development is generated by the continuous technical and economic innovation, what should be based on high level basic and applied research activity. For these reasons applied research based on high level may lay foundations. The utilization of the result of basic research may mean a lasting economic benefit. A country needs him for this for well-funded one to be, has to pursue a research-developmental activity with suitable intensity. Currently the intensity of R&D activity is very diverse in the world's countries, the R+D proportions of expenditures to GDP are between 0.8 and 5.0 %. The low research intensity is typical of the poorer countries, generally. Big efforts are put onto the increase of the efficiency of the research and...

A Quality-Adjusted Cost Index for Estimating Future Consumer Surplus from Innovation AgEcon
Austin, David H.; MacAuley, Molly K..
This paper describes a model for estimating, in a probabilistic framework, expected future consumer surplus from planned new product innovations. The model has been applied to estimations of taxpayer benefits from NASA's New Millenium Program (NMP), which develops new technologies for space science, and to the digital data storage technologies being supported by the Department of Commerce's Advanced Technology Program (ATP). The model uses cost index methods based on consumers' estimated marginal valuation for quality improvements in the technology. Probabilistic values for performance increases are taken from the innovators' own expectations. The analysis reveals the sensitivity of welfare increases to these values, which are assumed to be biased upward....

Economic expansion revaluates continuously the economic and social role of agriculture. Population explosion in the world generates continuously growing demand on foods and industrial raw materials. Supply of increased demand is supported by R&D, at the same time using results of it polarizes the economies. In the agriculture the technical development (i.e. development of technical, technological and biological basis of production, chemicalization, education of human resources) produces potential for increasing efficiency of production. The first period of technical development serves characteristically the supply of quantitative demand, but after it reached the equilibrium of supply and demand, then qualitative development becomes aim.

Adjustment and Differences in Farm Performance - a Farm Management Perspective from the Netherlands AgEcon
Poppe, Krijn J.; van Meijl, Hans.
There are differences in performance between farmers. In the Netherlands this has been a major topic of research for at least 30 years. Research has shown that the managerial capacities of farmers play a major role in differences in economic and environmental performance. Management can be measured and the optimal level is not the maximum level. Farmers differ in their objectives, competences and local external situation and therefore their strategies. These strategies can be identified. In recent years strategic management has become more important and this can be supported with consultancy. Farmers also differ in their adoption and innovation behaviour. These micro economic results, that correlate with large differences in income and high prices of fixed...

An Economic Assessment of Space Solar Power as a Source of Electricity for Space-Based Activities AgEcon
MacAuley, Molly K.; Davis, James F..
We develop a conceptual model of the economic value of space solar power (SSP) as a source of power to in-space activities, such as spacecraft and space stations. We offer several estimates of the value based on interviews and published data, discuss technological innovations that may compete with or be complementary to SSP, and consider alternative institutional arrangements for government and the private sector to provide SSP.

ANALYSING THE LOW ADOPTION OF WATER CONSERVATION TECHNOLOGIES BY SMALLHOLDER FARMERS IN SOUTHERN AFRICA AgEcon
Perret, Sylvain R.; Stevens, Joe B..
Natural resource degradation and water scarcity are a global concern, which typically threatens the sustainability of smallholder farmers' livelihoods in semi-arid developing areas. As part of research efforts, a number of water-conservation technologies (WCT) have been developed, yet with low adoption rates in smallholder farming environments. This paper discusses the concepts of adoption and innovation, comparing the perspectives of research operators to the ones of smallholder farmers. Discrepancies are highlighted and ultimately explain low uptake of technologies by farmer. Then it addresses socio-economic factors affecting such adoption. It is argued that WCT show specific traits: (1) diversity and applicability to different time and spatial...

Analysis of Farm Development in Dutch Agriculture and Horticulture AgEcon
Bremmer, Johan; Oude Lansink, Alfons G.J.M.; Olson, Kent D.; Baltussen, Willy H.M.; Huirne, Ruud B.M..
This paper analysis the effects of farmer characteristics, farm structure and farm performance on farm renewal and farm growth. The data set used in this research consists of panel data from the Dutch Farm Accountancy Data Network of farms specialized in plant production extended with a data from survey among those farms. Probit models were used to determine the likelihood of the changes. Results show that the degree of mechanization increases the probability of farm growth and farm renewal. Family labour input and solvency have a negative impact on farm growth. Farm size is positively correlated with farm renewal. No indications of the influence of the life cycle have been found.

Analysis on Farmers’ Land Right Protection AgEcon
Wei, Feng-xiu.
Land is the fundamental income sources for farmers. However, farmers stay in disadvantaged state in the political, economic and social aspects. Their land is exploited and occupied, which facilitates the rapid development of economy, as well as brings the gap between the poor and the rich and the inharmonious disputes. The necessity for protecting the land right of farmers under the new situation is expounded, covering the necessity of carrying out the relevant agricultural policies; the necessity of improving rural economic status and narrowing the gap between urban and rural areas; the necessity of reducing land disputes and constructing harmonious society. The violation of farmers’ land rights is analyzed from two aspects. The first one is the violation...
