| Risk in the agricultural sector has multiple dimensions or factors and prioritization of these can support decision making. On the other hand, knowing the importance of these risk factors for distinct agricultural activities and how they vary according to geographic zone constitutes relevant information for agricultural development. The objective of this study was to prioritize risk factors that are highly relevant for farmers in Central South Chile. The multi-criteria Analytical Hierarchical Process (AHP) methodology was used to define a decision structure with four risk factors or criteria: climate, price and direct cost variability, human factor, and commercialization. In general, results obtained showed that there are no important imbalances in the... |

| This study aims to weigh the influence of observable traits on live cattle prices, i.e., the percent impact on the final price of various physical characteristics. These characteristics are those that commonly are published in auction catalogues, as is the case of: average lot weight, lot size, age, breed and corporal condition. In addition, the influence of seasonality and business cycles were also explored. Using the data collected from the records of El Tattersall S.A., a hedonic price function was fitted. The results showed that the most influential variables with respect to the price of beef cattle, in decreasing order, are as follows: 'condition', 'breed', 'quarter of sale' and 'year', which are followed far behind by 'lot size' and 'average weight'.... |

| Integration of the Chilean domestic economy into international markets has created the need to incorporate more technology, information, and management tools and to generate better entrepreneurial skills at the farm level. These changes require the development of strategic capabilities and farmer changes in attitude. The goal for farmers is to be more prepared for the decision-making process and to have adequate evaluation and control systems to face the complexity of the farm business. The literature suggests that using management tools positively correlates with profits and concludes that management skills are positively related to farmers' well-being. Survey information on 211 farmers from central and southern Chile was used to estímate a probit model... |

| Cereal grain yields have increased worldwide during the 20th century as a consequence of plant breeding, improved cultural practices and intensive use of inputs. However, there is evidence that there are differences in yield pattern evolution across countries and cereals. The purpose of this study was to compare trends in the yields of the most commonly produced cereals in Chile, namely wheat, oat, barley, maize and rice, to identify similarities in trends across crops and to estimate long-term growth rates in the yields and their changes over time. Data for wheat, barley, oat, rice and maize yields between 1929 and 2009 were obtained from the Chilean Oficina de Estudios y Políticas Agrarias (ODEPA). A first-order autoregressive (AR1) model with trend was... |
