2009 PRECISION AGRICULTURAL SERVICES DEALERSHIP SURVEY RESULTS AgEcon
Whipker, Linda D.; Akridge, Jay T..
In the spring of 2009, Crop Life magazine and Purdue University’s Center for Food and Agricultural Business conducted a survey of crop input dealers for the 14th consecutive year. In February, a questionnaire was mailed to 2500 Crop Life retail crop input dealership readers across the US. (See Appendix I to this report for a copy of the questionnaire.) A total of 258 questionnaires were returned, with 241 being usable. This provided an effective response rate of 9.6 percent, the lowest response rate in the 14 year history of the project. (In prior years, response rates have ranged from a high of 38 percent in 1996 to a low of 11 percent in 2001 and 2008.) Consistent with previous surveys, dealerships were asked questions about the types of precision...

Current Contribution of Four Biotechnologies to New Zealand's Primary Sector AgEcon
Kaye-Blake, William; Saunders, Caroline M.; Emanuelsson, Martin.
Over the last several decades, changes to production technologies have significantly increased output from the primary sector. The contribution of improved genetics has been variously estimated, and the impacts of genetic engineering have received much attention. The present research estimated the economic impact of four modern biotechnologies (other than genetic engineering) on the primary sector. Information from interviews with key informants was incorporated into a cost-benefit analysis to estimate these impacts. The net contribution was estimated at $266 million per year, with impacts spread unevenly through the sector and across biotechnologies.

Technology Capital: The Price of Admission to the Growth Club AgEcon
Evenson, Robert E.; Fuglie, Keith O..
We assess long-run patterns of global agricultural productivity growth in developing countries between 1970 and 2005 and examine the relationship between investments in technology capital and productivity. To measure agricultural total factor productivity (TFP) we employ a Solow-type growth accounting method to decompose output growth into input and TFP growth. For technology capital we construct two indexes reflecting national capacities in agricultural research and education-extension for 87 developing countries. We then correlate technology capital levels with long-term growth rates in agricultural TFP. Our findings show that average agricultural TFP growth in developing countries accelerated in the 1980s and 1990s but fell marginally in the early...

Environmental Options and Technological Innovation: An Evolutionary Game Model AgEcon
Antoci, Angelo; Borghesi, Simone; Galeotti, Marcello.
This paper analyses the effects on economic agents' behaviour of an innovative environmental protection mechanism that the Public Administration of a tourist region may adopt to attract visitors while protecting the environment. On the one hand, the Public Administration sells to the tourists an environmental call option that gives them the possibility of being (partially or totally) reimbursed if the environmental quality in the region turns out to be below a given threshold level. On the other hand, it offers the firms that adopt an innovative, non-polluting technology an environmental put option that allows them to get a reimbursement for the additional costs imposed by the new technology if the environmental quality is above the threshold level. The...

Technology, Trade, and Income Distribution in West Germany: A Factor-Share Analysis, 1976-1994 AgEcon
Ochsen, Carsten; Welsch, Heinz.
This paper examines the determinants of functional income distribution in West Germany. The approach is to estimate a complete system of factor share equations for low-skilled labor, high-skilled labor, capital, energy, and materials, taking account of biased technological progress and increasing trade-orientation. Technological progress is found to reduce the share of low-skilled labor and to raise the share of high-skilled labor. The effect of technology bias on the two labor shares is enhanced by substitution of intermediate inputs for lowskilled labor, which is almost absent in the case of high-skilled labor. Trade-induced changes in the composition of aggregate output tend to mitigate these effects, due to the relatively favorable export performance...

The Environment and Directed Technical Change AgEcon
Acemoglu, Daron; Aghion, Philippe; Bursztyn, Leonardo; Hemous, David.
This paper introduces endogenous and directed technical change in a growth model with environmental constraints. A unique final good is produced by combining inputs from two sectors. One of these sectors uses "dirty" machines and thus creates environmental degradation. Research can be directed to improving the technology of machines in either sector. We characterize dynamic tax policies that achieve sustainable growth or maximize intertemporal welfare. We show that: (i) in the case where the inputs are sufficiently substitutable, sustainable long-run growth can be achieved with temporary taxation of dirty innovation and production; (ii) optimal policy involves both “carbon taxes” and research subsidies, so that excessive use of carbon taxes is avoided;...

The Determinants of the Global Digital Divide: A Cross-Country Analysis of Computer and Internet Penetration AgEcon
Chinn, Menzie D.; Fairlie, Robert W..
To identify the determinants of cross-country disparities in personal computer and Internet penetration, we examine a panel of 161 countries over the 1999-2001 period. Our candidate variables include economic variables (income per capita, years of schooling, illiteracy, trade openness), demographic variables (youth and aged dependency ratios, urbanization rate), infrastructure indicators (telephone density, electricity consumption), telecommunications pricing measures, and regulatory quality. With the exception of trade openness and the telecom pricing measures, these variables enter in as statistically significant in most specifications for computer use. A similar pattern holds true for Internet use, except that telephone density and aged dependency...

Stochastic Production Frontiers and Decomposition of Output Growth: The case of citrus-growing farms in Tunisia AgEcon
Dhehibi, Boubaker; Elloumi, Mohamed.
The aim of this paper is to investigate the relative contribution of technical efficiency, technological change and increased input use to the output growth of the Tunisian citrus growing farms using a stochastic frontier production function approach applied to panel data for the period 2003-2005. Knowledge of the relative contribution of factors productivity and input use to output growth and improvements in technical efficiency is crucial to provide a comprehensive view of the state of the citrus producing sector in the country and help farm managers and policy makers draw appropriate policy measures. The proposed methodology is based on the use of a flexible translog functional form. Results indicate that technical efficiency of production in citrus...

Intellectual Property Rights and Innovation in Developing Countries: Evidence from Panel Data AgEcon
Leger, Andreanne.
The determinants of innovation and the role of intellectual property rights in different countries are not well understood. This paper estimates the determinants of innovation using a new panel dataset. It compares different panel estimation methods appropriate for finite size samples. Past R&D investments have a positive and significant impact on current innovation, while openness to trade has a negative and significant impact on innovation in developing countries and population size has a negative and significant impact on innovation in industrialized countries. Intellectual property protection is not significant for any of the groups. We discuss econometric issues and the policy implication of these results.

Análisis económico de la “bio-carbonización” como práctica de manejo agrícola AgEcon
Ramirez, Juan Andres; Rosales Alvarez, Ramon.
Las altas concentraciones de gases de efecto invernadero, específicamente CO2, han sido señaladas como la principal causa del cambio climático. La adopción de prácticas agrícolas capaces de incrementar el contenido de carbono en el suelo, ha sido propuesta como una estrategia de bajo costo y disponibilidad inmediata para enfrentar este fenómeno. La Bio-carbonización es una de estas prácticas agrícolas, la cual implica la aplicación de carbón vegetal al suelo, de modo que el carbono queda capturado en una forma altamente recalcitrante al tiempo que se mejora la calidad del suelo. Este artículo es el primero en evaluar la viabilidad financiera y considerar algunos de los efectos económicos de la práctica, estimados para una finca tipo en la altillanura...

Learning in Organic Farming – An Application on Finnish Dairy Farms AgEcon
Sipilainen, Timo; Oude Lansink, Alfons G.J.M..
Organic farming technology may be relatively unknown to farmers at the time when they switch from conventional into organic farming. Therefore, experience gained over time and learning by doing may be important determinants in the efficiency of organic farming. It may also take time to reach the optimal nutrient stock of soil and optimal nutrient supply for arable crops under organic farming. Thus, efficiency of organic farming can either grow or decrease over time depending on the nature of the technology and the learning process. This paper estimates technical efficiency of organic farming and its development over time. We control for possible selection bias and regional heterogeneity when estimating a stochastic frontier distance functions for a sample...

Water Saving Technology in Chinese Rice Production - Evidence from Survey Data AgEcon
Abdulai, Awudu; Glauben, Thomas; Herzfeld, Thomas; Zhou, Shudong.
Whereas water is an important input in rice production, China faces severe problems with increasing demand for water and limited water resources. In conventional paddy production, one of the most important irrigated crops, a significant amount of irrigation water is lost due to percolation and evaporation. Therefore, it exist a vivid research in water saving rice technologies. This paper analyzes the adoption of one of these water-saving rice production technologies, the so-called Ground Cover Rice Production System (GCRPS), in the Hubei province. Based on farm survey data several factors which affect the adoption decision could be identified. The adoption decision is treated as a binary choice problem and therefore a probit model is used for the...

Dung, Khong Tien; Sumalde, Zenaida M.; Pede, Valerien O.; McKinley, Justin D.; Garcia, Yolanda T.; Bello, Amelia L..
This study has evaluated the technical efficiency of farmers engaged in rice-wheat cropping systems in North-eastern India, who are using Resource-Conserving Technologies (RCTs) such as Zero Tillage (ZT) and Direct Seeded Rice (DSR). These technology promotions are being carried out under the intervention of the Cereal Systems Initiative for South Asia (CSISA) project, primarily funded by the Bill and Melinda Gates Foundation. The resource-conserving technologies are being promoted as part of conservation agriculture supported by the project. The data used in this study have been derived from the socioeconomic surveys conducted in Eastern Uttar-Pradesh and Bihar in North-eastern India during the kharif season of 2009 and rabi season of 2010. A stochastic...

IMPERIALISM AND COMPETITION IN ANTHROPOLOGY, SOCIOLOGY, POLITICAL SCIENCE AND ECONOMICS: A PERSPECTIVE FROM DEVELOPMENT ECONOMICS AgEcon
Ruttan, Vernon W..
In work published in the 1980's Yujro Hayami and I elaborated a theory of institutional innovations in which institutional changes are induced, on the demand side, by changes in relative resource endowments and technical change and, on the supply side, by changes in cultural endowments and advances in social science knowledge. In the mid-1980's I initiated a research program to explore what development economists might learn from research by other social scientists working in the field of development. In this paper I draw on this earlier work, and on related literature to explore the conditions under which interdisciplinary imperialism or interdisciplinary collaboration can be most productive. I argue that when the objective of research is to advance...

Optimal Timing of Environmental Policy; Interaction Between Environmental Taxes and Innovation Externalities AgEcon
Gerlagh, Reyer; Kverndokk, Snorre; Rosendahl, Knut Einar.
This paper addresses the impact of endogenous technology through research and development (R&D) and learning by doing (LbD) on the timing of environmental policy. We develop two models, the first with R&D and the second with LbD. We study the interaction between environmental taxes and innovation externalities in a dynamic economy and prove policy equivalence between the second-best R&D and the LbD model. Our analysis shows that the difference found in the literature between optimal environmental policy in R&D and LbD models can partly be traced back to the set of policy instruments available, rather than being directly linked to the source of technological innovation. Arguments for early action in LbD models carry over to a second-best...

2008 PRECISION AGRICULTURAL SERVICES DEALERSHIP SURVEY RESULTS AgEcon
Whipker, Linda D.; Akridge, Jay T..
Precision technologies are now well-integrated into the agricultural industry – both at the farm level and at the crop input dealer level. No longer are crop input dealers only using the technologies to bring new services to their customers, they are also utilizing the technology in their own businesses to improve the efficiency and effectiveness of their operations. In early 2008, Crop Life magazine and Purdue University’s Center for Food and Agricultural Business conducted a survey for the 13th consecutive year to assess the adoption of precision agriculture practices in the U.S. from the perspective of the retail crop input dealer. The questionnaire was mailed to 2500 retail crop input dealerships across the U.S. A total of 298 questionnaires were...
