    Cost analysis and technical efficiency of dairy cattle farms: a case study of Artvin, Turkey
    (Univ Fed Rural Pernambuco, Dept Administracao, 2020) Aydemir, Aslihan; Gozener, Bilge; Parlakay, Oguz
    In this study, cost analysis and technical efficiency was performed for dairy cattle farms in Artvin province of Turkey, milk production costs were calculated and the factors influencing milk production were identified. Technical efficiency scores of dairy farms were also calculated with Data Envelopment Analysis (DEA). Research data were gathered through the questionnaires with 118 dairy cattle farms selected through random sampling method. Total production costs per farm was calculated as 17 557.64 USD and 57.76% of such a sum was constituted by variable costs and 42.24% by fixed costs. The average cost of 1-liter milk was calculated as 0.32 USD. Of average active capital of the dairy cattle farms, 61.27% was composed of operational capital and 38.73% was composed of land capital. Economic rentability was 39.44%, financial rentability was 39.50% and rentability factor was 67.94%. Of milk production costs, 57.76% was composed of variable costs. According the DEA, average efficiency scores of dairy farms was identified as 65.00%. The Tobit analysis performed to put forth the relationships between DEA efficiency scores and socio-economic variables of the dairy farms revealed that inefficiency scores increased with increasing herd sizes.

    Production cost and technical efficiency in the enterprises producing sunflower in dry conditions: a case study of Edirne, Turkey
    (Univ Fed Rural Pernambuco, Dept Administracao, 2016) Parlakay, Oguz; Gozener, Bilge; Sayili, Murat
    The aim of this study is to determine the production cost of sunflower produced for oil in dry conditions and to estimate the technical efficiency of the enterprises. In this context, main material of the study consists of the data gathered by the surveying of the 112 enterprises determined randomly that produce sunflower in Edirne which are chosen deliberately since sunflower production is excessively. In the study, production cost is determined by calculating the production expenses and the revenue gained by this production. Also, technical efficiency scores of the enterprises are estimated by using Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA) methods. As a result of the calculations, sunflower production cost is determined as 585,36 USD tonnes-1, and the revenue from the production (except for the supports) is determined as 560,00 USD tonnes-1. Also, technical efficiency scores are estimated with SFA as 0,87 and with DEA-VRS as 0,83. From the findings, it is understood that without supports given for the sunflower production, producers would make a loss and the supports should be continued.
