Technical Efficiency of Grain Production in Ukraine AgEcon
Kurkalova, Lyubov A.; Jensen, Helen H..
A stochastic production frontier model with technical inefficiency effects is estimated on a representative sample of Ukrainian state and collective grain-producing farms. Technical efficiency declined from 1989 to 1992. More experienced managers were found to be more productive, with the effect of experience diminishing with age. We found that on-farm provision of production infrastructure was associated with higher efficiency, a result supporting the hypothesis that disorganization causes output to decline in transition economies.
Tipo: Working or Discussion Paper Palavras-chave: Technical efficiency; Stochastic production frontier; Economies in transition; Grain production; Disorganization hypothesis; Crop Production/Industries.

Production Efficiency in Ukrainian Agriculture and the Process of Economic Reform AgEcon
Kurkalova, Lyubov A.; Jensen, Helen H..
A representative sample of 49 state and collective farms in Ukraine provides data in physical units on livestock and crop production and input use for 1989-92. The changes in production efficiency for beef, pork, dairy, winter wheat, grain, and potato production, investigated using stochastic frontier methods, show declining technical efficiency in livestock production and especially low marginal contribution of labor inputs. The number of workers, size of farm, and distance from nearest city are related to efficiency in agricultural production.
Tipo: Working or Discussion Paper Palavras-chave: Technical efficiency; Panel data; Economies in transition; Frontier production function; Productivity Analysis.

Relative Growth of Subsidiary Farming in Post-Soviet Economies: A Labor Supply Story AgEcon
Kurkalova, Lyubov A.; Jensen, Helen H..
An agricultural household model (AHM) is applied to analyze the changes in labor supply of post-Soviet households. Extensions of the model are presented in which wage and pension arrears are modeled as income uncertainty. Considering two models, one for wage earning households and another for pensioners, we find that wage and pension uncertainties increase subsidiary farming hours and so does a mean-preserving spread in the distribution of pensions. A decline in the probability of receiving wages not only increases subsidiary farming hours but also reduces wage work hours.
Tipo: Working or Discussion Paper Palavras-chave: Income uncertainty; Wage arrears; Agricultural household model; Labor supply; Economies in transition; Subsidiary farming; Farm Management; Labor and Human Capital.
