Attitudes and Preferences of Urban and Rural Households Towards Chicken Meat Consumption: Case Study of Hakkari, Turkey
(WFL Publisher Ltd., 2013) Şahin, A.; Yildirim, I.; Deniz, A.
The consumers are more concious regarding the chicken consumption due mainly to risks stemming from the diseases and health concerns. Thus, in recent years important consumption pattern variations are observed. This study examines chicken consumption structure of 95 urban and 95 rural households comparatively in Hakkari, Turkey, which has special socio-cultural structure being bordered by Iran and Iraq. Double logarithmic regression model was used to determine the price and income elasticities of chicken meat demands. Monthly chicken meat consumption per households and per capita were 5.3 kg and 0.9 kg for urban and 4.2 kg and 0.59 kg for rural households, respectively. Cheapness was the most important determining factor in preference of meat types of urban households with 43.6% followed by habit with 34.0%. On the other hand, habit and convenience were the main determinant factors effective on the preference of chicken meat with 40.0% each. Price elasticity of per capita chicken meat demand was - 0.653 and income elasticity of per capita chicken demand was 0.114.
A Comparison of Profitability Between Culture and Native-Breed Dairy Farms (Case Study of Eastern Part of Turkey)
(2006) Yildirim, I.; Şahin, A.
The comparison of the profitability of culture and native-breed dairy fanns was aimed in this study. The hypothesis that culture-breed dairy farms are more profitable as well as more cost-efficient in producing one unit of milk and that the profitability increases in proportion to farm size was tested. The material was collected from 40 culture and 16 native-breed dairy farms in Center town of Van province, Turkey. The data belong to 1999 production period. The number of cow per farm, dady milk per cow, lactation period, milk production per cow per lactation and total milk production per farm was 8.3, 7.63 kg, 225.5 days, 1720.6 and 14289.7 kg, respectively for culture-breed dairy farms. The same figures were relatively lower for native-breed dairy farms with 4.4, 3.24 kg, 208.13 days, 674.3 and 2.967 kg, respectively. Economical profitability was positive with 3.27% for culture-breed farms while this figure was negative for native-breed farms with -1.14%. Both economical and financial profitability increased in parallel to farm size. The cost of 1 kg of milk was calculated as $0.47, which is 60% higher than that of culture-breed dairy farms. This figure decreased in proportion to farm size. The total production elasticity of inputs found by coob-douglas production function for culture-breed dairy farms was 2.97, winch means there is an increasing return to the scale. We can suggest that the scale is effective on the profitability and expanding the culture-breed dairy enterprise could increase the profitability due to economies of scale. © 2006 Academic Journals Inc.
The Impact of Climate Policy Uncertainty on Agricultural Investments
(Turkish Journal of Agricultural Economics, 2025) Karagöl, V.; Şahin, A.
Purpose: The agricultural sector is strategically important for sustainable development and food security. However, climate change and the increasing physical and political uncertainties that come with it put investments in this sector at risk. This study examines the relationship between climate policy uncertainty and agricultural investments in the USA from 1995-2022. Design/Methodology/Approach: The nonlinear ARDL method and asymmetric causality test are used to analyze the relationships between climate policy uncertainty and agricultural investments. Nonlinear methods allow us to measure asymmetric effects on the dependent variable by evaluating the positive and negative changes of the explanatory variables separately. Findings: According to the NARDL model results, increases in climate policy uncertainty reduce agricultural investments in the long run. The asymmetric causality test provides additional evidence for the asymmetric relationships identified by the NARDL model. There is a statistically significant asymmetric causality from the positive shock of climate policy uncertainty to the negative shock of agricultural investments. Originality/Value: This study fills the gap in the literature by examining the impact of climate policy uncertainty on investments in the agricultural sector. This provides a new perspective to understand the long-term consequences of this relationship in a highly climate-sensitive area such as the agricultural sector. © 2025, Turkish Journal of Agricultural Economics.

Technical, Allocative and Economic Efficiencies of Turkish Dairy Farms: an Application of Data Envelopment Analysis
(2010) Günden, C.; Şahin, A.; Miran, B.; Yildirim, I.
Efficiencies of farms were measured using data envolepment analysis (DEA) on 87 dairy farms in İzmir, Turkey. Technical, allocative and economic efficiencies were 0.615, 0.673 and 0.488, respectively. Only three farms were efficient. 62% of farms had decreasing return to scale. It is concluded that the current gross production value could be preserved while decreasing the number of cows, labor (man-days) and maize silage (kg) by 50.29, 45.17 and 42.42%, respectively. © GSP, India.
