Herbicide-resistant (HR) rice technology is a potential tool for control of red rice in commercial rice production. Using an ex ante mathematical programming framework, this research presents an empirical analysis of HR rice technology adoption under uncertainty. The analysis accounts for stochastic germination of red rice and sheath blight to model a profit maximization problem of crop rotation among HR rice, regular rice, and soybeans. The results demonstrate that risk attitudes and technology efficiency determine adoption rates and optimal rotation patterns.

Bullock, David S..

It is well recognized that the statistical reliability of the conventional method of estimating the effects of technological change on producer welfare is often quite poor. I present a method that enhances the statistical reliability of such estimates. I emphasize that when measuring the welfare effects of technological change, valuable information can be gleaned from data on input prices and quantities. This type of data is often available, but the conventional measure typically does not take full advantage of its availability. Letting T0 be some initial level of technology and T1 be a subsequent level, the conventional measure of producer welfare change due to a technology change is the change in the “triangle” area under the price and behind the...

Adoption of herbicide-tolerant cotton and conservation tillage may be simultaneously related. Bayes' theorem and a two-equation logit model were used to test the simultaneity hypothesis. Evidence for Tennessee suggests that adoption of these technologies reduced residual herbicide use and soil erosion more than if adoption of these technologies were independent.

This article undertakes an empirical investigation of the determinants of voluntary adoption of the ISO 14001 environmental management system by French farmers. The adoption model incorporates the expected profitability of implementing the standard and investigates the impact of prior knowledge on the probability of adopting. Two information measures are considered: a “reported information” indicator and an “estimated knowledge” score. The probit parameter estimates reveal that, while the expected profitability of implementing the standard is a significant determinant of adoption, real and perceive prior knowledge measures play a significant but potentially counterintuitive role.

A nested logit model was used to analyze the 2009 Southern Cotton Precision Farming Survey to study the impact of farmer and farm characteristics on the adoption of Variability Detection Technologies (VDT) and the adoption of Variability Rate application Technology (VRT) conditioned on the type of the VDT chosen. The results showed that the farm size and exposure to extension activities are important factors affecting the choice of VDTs. The farmers adopting both soil and plant based VDTs are more likely to adopt VRT. The probability of adoption of VRTs was lower for Texas cotton farmers irrespective of the type of VDT adopted. In general, younger, more educated farmers who use computers for farming operations are more likely to adopt VRT when they...

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.

We employ propensity score matching (PSM) framework to examine the impact of sweet potato-based feed technology adoption on household-based pig production in Sichuan, China. An ex post survey in six villages was conducted in 2009, of which five villages were in project intervention sites (exposed area) and one village in the same township but not exposed to project intervention (non-exposed area). We randomly selected 111 households in the exposed areas from the list of households previously interviewed in a baseline survey and 53 households from non-exposed area. Matching estimators such as nearest neighbor matching (NNM), radius matching (RM) and kernel matching (KM) were used to estimate average treatment effects. Results indicate positive net benefit...

Pests like the larger grain borer (P. truncatus) and the maize weevil (S. zeamis) cause significant storage losses for African maize producers. The value of storage protection to a market-oriented farmer is a function of price seasonality, value loss prevention, and their opportunity costs of capital. Evidence suggests that hermetic technologies like Purdue Improved Crop Storage (PICS) bags can be effective against these key maize storage pests, but sustainable technology transfer requires that it be profitable for producers. This analysis references dry weight loss figures from key life science articles and builds on previous value loss research to provide a geographic model for potential storage technology adoption. PICS bag profitability with one and...

This article presents an integrated assessment of climate change, air pollution, and energy security policy. Basis of our analysis is the MERGE model, designed to study the interaction between the global economy, energy use, and the impacts of climate change. For our purposes we expanded MERGE with expressions that quantify damages incurred to regional economies as a result of air pollution and lack of energy security. One of the main findings of our cost-benefit analysis is that energy security policy alone does not decrease the use of oil: global oil consumption is only delayed by several decades and oil reserves are still practically depleted before the end of the 21st century. If, on the other hand, energy security policy is integrated with optimal...

This paper contributes to the induced innovation literature by extending the analysis of supply and demand determinants of innovation in energy-efficient technologies to account for international knowledge flows and spillovers. In the first part of the paper we select a sample of 38 innovating countries and we study how knowledge related to energy-efficient technologies flows across geographical and technological space. We demonstrate that higher geographical and technological distances are associated with a lower probability of knowledge flow. In the second part of the paper, we use our previous estimates to construct stocks of internal and external knowledge for a panel of 17 countries and present an econometric analysis of the supply and demand...

We study the driving forces behind the adoption of environmental innovations (EI) in the Italian industry over 2006-2008 through analyses of the new wave of Community Innovation Survey (CIS) data that covered for the first time environmental innovation adoptions. We investigate whether the first phase of EU ETS has exerted some effects on environmental innovations by using a very large sample of italian manufcturing firms. Estimates show that external forces and complementarity with other management practices are particularly relevant to increase the adoption of relatively new and radical technologies: relationships with other firms and institutions, local public funding, group membership are the key factors. The role of ETS on EI seems instead to be weak:...

Changing role of BRIC countries in technology-driven international division of labor

Community Pressure and Clean Technology in the Informal Sector: An Econometric Analysis of the Adoption of Propane by Traditional Mexican Brickmakers

Gryczka, Marcin.

In contemporary international division of labor the importance of ICT technologies and social capital is increasing, and allows the economy to be more competitive due to arising many connections to the global information networks. The major goal of this article was analyzing (mostly in descriptive manner) and comparing the recent trends in GDP growth and its composition and international trade of high-technology manufactures and services for developed and BRIC countries. The results of conducted statistical data analysis justify the conclusion that some developing economies, especially China and India, are in fact gaining on importance in international trade of high-tech products and knowledge-intensive business services, even having become more effective...

Blackman, Allen; Bannister, Geoffrey J..

In many developing countries the informal sector, comprised of low-technology unlicensed micro-enterprises, is a major source of pollution. Environmental management in this sector is exceptionally challenging. Though clean technologies offer a means of mitigating the problem, to our knowledge there has been no rigorous empirical research on why informal (or even small-scale) firms do and do not adopt them. As a first step towards filling this gap, this paper presents the results of an econometric analysis of the diffusion of propane among informal 'traditional' brickmakers in Cd. Juárez, Mexico--a leading source of air pollution owing to their reliance on cheap, highly polluting fuels such as used tires and scrap wood. The two key policy implications of...

This study provides a stylized model on “Exit, voice and loyalty” as alternative strategic responses taken by Kenyan green beans farmers in the context of new and more stringent international food safety standards. On the analytical side, we use the Nash bargaining theory where the exporter and a representative grower bargain over the product quality level and the premium producer price. The comparative statics analysis shows that the producer bargaining power unlike the compliance costs has, ceteris paribus, a positive effect on the equilibrium quality level while these exogenous variables have ambiguous effects on producer price at equilibrium. Empirical results from logit model estimation with survey data at farm-level in Kenya show that households with...

Cross-Border Securities Clearing and Settlement Infrastructure in the European Union as a Prerequisite to Financial Markets Integration: Challenges and Perspectives

de Carvalho, Cynthia Hirata.

The importance of an efficient securities clearing and settlement system lies on the safer transfer of ownership of assets against payment. Such a system must be developed in a way to minimize the risks involved on securities transactions, and it must still offer lower costs, which do not hinder the intention to acquire or dispose securities. The cross-border securities clearing and settlement transactions within Europe, especially equities transactions, are still much higher and riskier than if cleared and settled domestically. The fragmented structure of local securities depositories is hindering the integration of financial markets in Europe, because investors are not stimulated to enjoy opportunities cross-border. Thus a smoothly functioning integrated...

This paper empirically investigates the determinants of firms’ performance in the agri-food sector by using recent survey data for Denmark. Treating sales per employee as a proxy for value addition we estimate several bootstrapped regression models to draw conclusions on the marginal effects of potential performance determinants such as the form and nature of ownership, stage of the food chain and commodity sector, new product development, staff quality, firms’ competitive stance, and elements of firms’ strategy. To draw robust inferences we apply, besides the ordinary heteroscedasticity corrected Tobit ML-estimator, a nonparametric least absolute deviations estimator (LAD/CLAD) based on a quantile regression procedure. The results indicate that we cannot...
