Última Romanian Maize - Distorted Prices and Producer Efficiency AgEcon Sauer, Johannes; Balint, Borbala. This research aims at shedding empirical light on the relative efficiency of small-scale maize producers in Romania. Farmers in transition countries still face heavily distorted price systems resulting from imperfect market conditions and socioeconomic and institutional constraints. To capture such distortions we formulate a stochastic shadow-cost frontier model to investigate the systematic input-specific allocative inefficiency. We further adjust the underlying cost frontier by incorporating shadow price corrections and subsequently reveal evidence on farm specific technical inefficiency. Different models are estimated due to the imposition of curvature correctness and the effects on the individual efficiency estimates are shown. The empirical results...

Ano: 2006 URL: http://purl.umn.edu/25597 Defining and Characterizing Approaches to Farm Management AgEcon McBride, William D.; Johnson, James D.. Exploratory factor analysis was used to identify approaches to farm management based on a list of management questions posed to a sample of U.S. cash-grain farmers. Three approaches were identified by the factor analysis: price negotiation, long-term cost control, and input adjustment. Estimated factor scores regressed against farm and operator characteristics indicate a profile of producers using each approach that is closely related to stage-of-life of the farm operator and farm business. In addition to operator age and planning horizon, operator risk preference and farm organization and location were other important determinants of the approach to management.

Ano: 2006 URL: http://purl.umn.edu/43755 Romanian Maize - Distorted Prices and Producer Efficiency AgEcon Sauer, Johannes; Balint, Borbala. This study tackles the decomposition of efficiency with respect to agricultural production in transition economies by using a case study on small scale maize farmers in Romania. The underlying modelling assumption is that farmers in transition countries still face heavily distorted price systems. To capture such distortions a stochastic shadow cost frontier model is formulated to investigate the systematic input specific allocative inefficiency. We further adjust the underlying cost frontier by incorporating shadow price corrections and subsequently reveal evidence on farm specific technical inefficiency. Different models are estimated due to the imposition of curvature correctness. The empirical results confirm the underlying hypothesis of enduring...

Ano: 2006 URL: http://purl.umn.edu/14958 The information theoretic foundations of a probabilistic and predictive micro and macro economics AgEcon Judge, George G.. Despite the productive efforts of economists, the disequilibrium nature of the economic system and imprecise predictions persist. One reason for this outcome is that traditional econometric models and estimation and inference methods cannot provide the necessary quantitative information for the causal influence-dynamic micro and macro questions we need to ask given the noisy indirect effects data we use. To move economics in the direction of a probabilistic and causal based predictive science, in this paper information theoretic estimation and inference methods are suggested as a basis for understanding and making predictions about dynamic micro and macro economic processes and systems.
