TL;DR: It is proposed that when using SA for decision support, it can be very helpful to attempt to identify which of the following forms of recommendation is most appropriate, and that an understanding of Bayesian probability revision will help the modeller plan and interpret an SA.

TL;DR: In this paper, the authors evaluated the impact of water markets and transactions costs in Chile, and showed that the market transfer of water-use rights does produce substantial economic gains from trade in both the Elqui and Limari Valleys.

TL;DR: In this article, the authors examined the level of technical efficiency across ecological zones and farm size groups in paddy farms of the southern Indian state of Tamil Nadu and found that 90% of the variation in output among paddy (IR-20) farms in the state is due to differences in technical efficiency.

TL;DR: In this article, an econometric procedure for estimating Arrow-Pratt coefficients of risk aversion is derived, and the model of farmers allocating land among different crops, and time between leisure and labor, allows for testing Arrow's hypotheses of decreasing absolute risk aversion and increasing relative risk aversion.

TL;DR: In this paper, the authors used the restricted normalised profit function method to determine whether women rice farmers are less efficient than men rice farmers in Cote d'Ivoire.

TL;DR: In this paper, a model that focuses on the role of assets and consumption risk in influencing soil conservation adoption decisions in low-income farmers in the Philippines has been presented, and results from a reduced-form probit model of adoption are reported.

TL;DR: The authors reviewed the literature dealing with the link of agricultural prices and macroeconomic policies to agricultural supply with particular emphasis on Sub-Saharan Africa and pointed out that our understanding of the quantitative dimensions of agricultural supply response is weak given the importance of this assumed response for growth, poverty alleviation, and the environment.

TL;DR: In this article, the market efficiency hypothesis for coffee and cocoa futures using daily data for contracts with a maturity of 2 and 6 months was tested sequentially, and the unbiasedness was found to be robust across testing procedures.

TL;DR: In this article, the potential for applying conjoint analysis to aid the design and targeting of client-responsive modern crop varieties was discussed, and utilities were estimated using the choice-probability-based method of ordered probit.

TL;DR: The features and uses of some recent biophysical and bioeconomic simulation models in agricultural economics research and problems associated with earlier models are discussed and the extent to which recent simulators have addressed concerns is appraised.

TL;DR: In this paper, the authors analyzed linkages between growth, trade and the environment in Mexican agriculture with an empirical economy-wide model and found that free trade does not induce wholesale specialization in dirty agricultural activities.

TL;DR: In this paper, a stochastic varying coefficients frontier approach is applied on recent household survey data of 1000 grain farmers covering the periods 1993-1995 to investigate whether China has achieved its potential in grain production fully with the existing technology.

TL;DR: In this paper, the authors used Heckman's two-stage procedure to determine factors influencing smallholder farmers' adoption of a stall-feeding management system for improved dairy cattle in semi-arid Tanzania and other related technology packages.

TL;DR: The data set of the Ghana Living Standards Survey was utilized to analyse the principal determinants of health and nutrition of children under five in Ghana and a specific finding was a rather strong negative effect of prolonged breastfeeding on the nutritional status of children.

TL;DR: A quality-of-life index (QLI), a proxy measure of utility, is constructed by factor-weighted and simple-summation weighted aggregation of socio-psychological measures of well-being.

TL;DR: In this paper, the authors used stochastic dominance to determine the risk characteristics of phosphate fertilization of millet, sorghum and maize with commercial NPK fertilizer, rock phosphate and partially acidulated rock phosphate in Burkina Faso.

TL;DR: In this article, the effects of macroeconomic policy, environment, and violence variables on investment in irrigation in Colombia were quantified and compared to previous studies, and variables such as violence, climate, and governmental price and credit policies were used to explain changes in private investment.

TL;DR: In this article, the agricultural sector's relative prices are taken into account along with economy-wide factor market adjustments to compare the agricultural GDP of four major European countries compared with US agricultural growth for the period 1974-1993.

TL;DR: In this article, the authors used duality theory to develop a model of European Community agriculture and investigated the impact of the land set-aside provision of the recent package of reforms of the Common Agricultural Policy.

TL;DR: In this article, the authors investigated the impact of China's and Taiwan's accession to the World Trade Organization (WTO) on U.S. and world agricultural trade by means of a 12-region, 14-sector Computable General Equilibrium model for world trade and production.

TL;DR: In this paper, the impact of minimum access (MA) import on the supply and demand balance of rice, and the rice diversion areas in the future is also predicted, based on the recent development of rice policies in Japan.

TL;DR: The Australian Wheat Board and Canadian Wheat Board (CWB) have attracted attention recently because they are two of the largest state trading enterprises engaged in agricultural trade as discussed by the authors, however, during the past 6 years, similarities between the AWB and CWB have begun to diverge and the importance of their differences is becoming increasingly apparent.

TL;DR: In this paper, a stochastic dynamic model was constructed to analyze investment decisions of an individual farmer under risk in the presence of irreversibilities, embedded technical change and indivisible capital.

TL;DR: In this article, the authors examined the financial attractiveness of dairying to smallholders in an area of high dairy potential on the slopes of Mount Kilimanjaro and found that at prevailing prices, returns to dairies were around 20%.

TL;DR: In this article, the authors estimate production costs and elasticities of factor substitution for Zimbabwean smallholders, using a dual (cost function) approach with detailed data on prices paid and received by each farm.

TL;DR: In this paper, the authors present a process for ex-ante research evaluation which accounts for agroecological conditions for technology generation and adoption, as well as commodity market-structure.

TL;DR: In this article, the impacts of trade liberalization for India have been examined with an applied general equilibrium model with nine agricultural sectors, one non-tradeable nonagriculture sector and one tradeable non agri-commodity sector and with five rural and five urban expenditure classes.

TL;DR: In this paper, the authors estimate frontier production functions with cross-section data for the Spanish agrofood industry by using deterministic and stochastic parametric approaches, and compute the individual technical efficiency for each firm, compare the results and explain the relationship between technical efficiency and other relevant quantitative variables.

TL;DR: In this article, the authors investigated the effects of research and extension (R&E) activities on the extent and the direction of the bias of technological change in Japanese agriculture for the period 1960-1990 based on the translog cost function framework.
