An Econometric Analysis Of Apricot Supply And Export Demand In Turkey, İlkay Dellal, A. Ali̇ Koç
An Econometric Analysis Of Apricot Supply And Export Demand In Turkey, İlkay Dellal, A. Ali̇ Koç
Turkish Journal of Agriculture and Forestry
This study estimates a supply model for apricots and an export demand model for dried apricots for Turkey to provide unit-free measure coefficients for better supply and marketing management. Using parameter estimates from the models and sample average data, elasticities of long-run supply, price-yield and export of dried apricots were computed as 0.72, 0.54 and -0.87 respectively. From the price dependent export demand model, the price flexibility of dried apricots was calculated as -0.71. In this study, the import demand elasticities of dried apricots for major destination countries were estimated and found to be inelastic. An evaluation of aggregated household …
Population Densities Of Liriomyza Huidobrensis (Blanchard, 1926) (Diptera: Agromyzidae) In Insecticide-Treated And Non-Treated Cucumber Producing Greenhouses In The İzmir Region, Hasan Sungur Ci̇velek, Zeynep Yoldaş
Population Densities Of Liriomyza Huidobrensis (Blanchard, 1926) (Diptera: Agromyzidae) In Insecticide-Treated And Non-Treated Cucumber Producing Greenhouses In The İzmir Region, Hasan Sungur Ci̇velek, Zeynep Yoldaş
Turkish Journal of Agriculture and Forestry
Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) is an important pest in cucumber greenhouses in Çamönü (Menderes, İzmir), Turkey. This study was carried out during the spring and autumn production seasons in 1999 and 2000 in two greenhouses belonging to a local farmer, each of them 1000 m^2 in size. The infested leaves from insecticide-treated and non-treated greenhouses were sampled weekly. The leaves were sampled weekly from both greenhouses and kept in our laboratory under observation to compare the number of emerging leafminer adults. Despite the applications, during three of the four seasons examined, pest density in the insecticide-treated greenhouse was not …

Measuring The Market Power Of The Banana Import Market In Turkey, Seli̇m Adem Hatirli, Eugene Jones, Ali̇ Riza Aktaş
Turkish Journal of Agriculture and Forestry
Banana production in Turkey represents a small fraction of that required to meet domestic consumption. Domestic consumption totaled 188,000 t in 2000, whereas production amounted to just 64,000 t, or 34% of consumption. The gap between consumption and production is made up by imports and 5 multinational firms control the flow of more than 80% of the global banana trade. Given this firm dominance in the world trade of bananas, oligopoly theory would suggest the presence of underlying structural forces that could facilitate price-enhancing market power. As such, this study develops an integrated trade and new empirical industrial organization (NEIO) …
