For Thai farmers natural rubber is a significant product and an economic crop. It has also some social benefits of rubber cultivation in this country. Yet, rubber producers of Thailand have not been receiving intended revenues in spite of expanding planted areas and increasing production. Current paper focuses on Thailand's natural rubber market equilibrium which is influenced by global and local impacts. The paper uses two-stage least squares methodology in order to estimate demand and supply response of Thailand. Input costs, planted area, agricultural credit amount dedicated to agriculture, palm oil prices are explanatory variables of supply. Indonesia production, per capita income of the world, car production of the world, exchange rate and rubber production of Indonesia are explanatory variables of demand. Rubber price is endogenous variable while resuming variables are exogenous. The econometric analysis will present opportunities to understand how to increase the producer surplus by simulating abovementioned variables. Producer's surplus is calculated 10,719,174,750 USD/Year in the equilibrium conditions. When financial supports are increased, it caused about 9.5 percent decreases in producer's surplus. The impacts of bilateral agreements was simulated with 10% and the 5% decreases of production amount. There was almost no difference on producer's surplus in case of a production decrease of 5% or 10%.

(Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2019-01-01) Gürbüz, İsmail Bulent; GÜRBÜZ, İSMAİL BÜLENT; Madiyoh, Abdulhakim; Macabangin, Modassir; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarım Ekonomisi Bölümü.; 0000-0001-5340-3725; GWV-0927-2022; M-4349-2019
Khao yam or Nasi Kerabu is a type of a traditional food, holding an important place in food consumption in Southern Thailand and Northern Malaysia. It is commonly consumed for breakfast and a good source of high nutritional value due to the availability of different varieties of vegetables and herbs in the actual dish. The main material of this study is comprised data obtained from online questionnaire surveys performed during December 2018 with 130 participants from three province borders of Southern Thailand (Pattani, Yala, Narathiwas). One of the preeminent highlights of the study is the availability of Khao yam sellers nearby all of the respondents' homes. This indicates that Khao yam food business in southern part of Thailand is continuously expanding. More researchers and policy makers should take Khao yam business sector as positive source in developing new policies and strategies.
Economic evaluation of a prospective farm animal welfare program in Turkey
(Emerald Group Publishing Ltd, 2019-10-24) Turan, Özlem; GÜRLÜK, SERKAN; TURAN, ÖZLEM; Gürlük, Serkan; Madiyoh, Abdulhakim; Bursa Uludağ Üniversitesi/Ziraat Fakültesi; 0000-0003-4673-7086; 0000-0002-3159-1769; AAG-7236-2021; GWV-0927-2022; AAG-8099-2021
Purpose The purpose of this paper is to examine producer preferences for changing Farm Animal Welfare (FAW) levels in regards to sheep and goat husbandry in Bursa-Turkey. Design/methodology/approach The paper tests "panel estimators" in a stated preference data by using the payment card question format. Probit panels are employed to measure individual effects on FAW levels by considering producers' willingness to accept. Three different FAW levels were identified for valuation as "base" level, "better" level, and the "best" level. The current study suggests a protocol with WTA(P) nomenclature to resolve complexity issues in FAW studies by investigating producers rather than consumers because the scenarios regarding FAW levels include quite technical and difficult topics which are vague to consumers. Findings If half of the total number of the sheep and goats in Turkey are assumed to be in bad animal welfare conditions, which are worse than base level, the non-use benefits of bringing them to at least the base level would be about US$130.3m. Figures would be 166.2m US$/year and 175m US$/year for "better" and "best" FAW conditions, respectively. Originality/value This paper provides a contribution to the existing literature by examining the producers' responses to new FAW schemes. Also it helps policy makers to understand producers' environmental behavior as well as their sensitivity to FAW schemes.
Güneydoğu Asya Ülkeler Birliği’ne üye ülkelerin (asean) tarım sektörlerinin çok kriterli karar verme yöntemleri ile incelenmesi
(Bursa Uludağ Üniversitesi, 2020) Madiyoh, Abdulhakim; Gürlük, Serkan; Bursa Uludağ Üniversitesi/Fen Bilimleri Enstitüsü/Tarım Ekonomisi Anabilim Dalı.; 0000-0001-7517-8821
Bu çalışmanın amacı seçilmiş kriterleri kullanarak Güneydoğu Asya Ülkeleri Birliği’ne (ASEAN) üye ülkelerin tarım sektörleri performanslarını ortaya koymak, tarım politikalarındaki eksik yönleri belirlemek, rekabet avantajlarını araştırmak ve gıda ve beslenme politikalarına yön vermektir. Bu çalışmada Güney ve Doğu Asya Ülkeler Birliği’ne Üye Ülkelerin Tarım Sektörlerinin Çok Kriterli Karar Verme Yöntemleri ile İncelenmesi konusunda kullanılan veriler 1967-2016 yılları arasında Filipinler, Malezya, Tayland, Endonezya, Singapur, Bruney Darussalam, Vietnam, Laos, Myanmar ve Kamboçya olmak üzere 10 ülkenin zaman serisi verileri olan ikincil verilerdir. Adı geçen ülkelere ait kullanılan veriler 6 kriteri içermektedir; (1) havza toplam tarımsal üretim değeri (2) hayvansal ürünler için kendine yeterlilik miktarı kriteri (3) bitkisel ürünler için kendine yeterlilik miktarı kriteri (4) göç oranı (5) tarımdan kaynaklanan sera gazı emisyonları, ve (6) tarım ürünleri dış ticareti değeri bu kriterler olarak çok kriterlerli karar verme yöntemleri ile değerlendirilmektedir. TOPSIS ve ELECTRE yöntemi sonuçları karşılaştırıldığında, ideal çözümler oldukça benzerdir. Bu iki yöntemin analiz edilmesiyle, 1967 yılında ASEAN ülkelerinin kurulmasının başlangıcında tarım sektörleri performansında ise en başarılı ülkenin Tayland olduğu ortaya çıkmıştır. 1990 yılında ise Tayland ikinci sıraya geçmiş ve yerine Malezya birinci sırada yer almıştır. 2000 yılından 2016 yılına kadar olan dönemde Tayland ikinci sırada, Malezya ise en başarılı olan ülke tarım sektörleri performansı alanında birinci sırada yer almıştır.
