Determinants of Cocoa Export and its Effects on Local Prices in Cameroon
Louis Atamja,KyungRyang Kim 한국국제농업개발학회 2018 韓國國際農業開發學會誌 Vol.30 No.3
ECM 분석을 통해 카메룬 코코아 수출시 GDP와 비교우위가 주요 결정요인임이 밝혀졌다. 수출시장에서의 환율변동에 따른 코코아 수출가격의 변동은 국내 코코아 가격을 결정하는 주요인이다. 가격변동에 따라 수출되지 못하는 코코아의 국내 시장 공급은 과잉공급으로 연결되고 이는 국내시장가격의 현저한 하락을 초래한다. Co-integration and Error Correction Model (ECM) was used to provide the evidence that the GDP, Export price and the Competitive Advantage could be the main determinants of Cameroon Cocoa export. The fluctuation in cocoa export price (exchange rate) plays a key role in deciding domestic price in that the cocoa product not exported has been supplied to domestic market and the excessive supply has made the domestic price drop significantly.

농업은 고용, 식량 및 생계를 목적으로 하는 카메룬 경제의 중심이다. 그러나 카메룬 농업은 낮은 생산성, 비효율성 및 수입에 의존하여 전염병에 시달리고 있다. 이러한 이유로 본 연구는 카메룬 북서부 지역의 쌀 농가의 기술적 효율성을 조사했다. 구조화된 설문지와 인터뷰를 사용하여 144명의 농부로부터 데이터를 수집했다. 기술 통계 및 확률적 프런티어 분석을 사용하여 데이터를 분석하였다. 확률적 프런티어 분석의 결과는 분산 매개 변수 (시그마 제곱 및 감마)가 통계적으로 유의하다는 것을 보여준다. 농장 규모, 비료, 노동 및 제초제의 계수는 긍정적이고 중요했다. 평균 기술 효율성 수준이 84%로 나타낸 것은 가용 자원을 효율적으로 활용한다면 쌀 농민의 기술 효율성을 16%로 증가할 수 있다. 비효율성 모델은 신용 액세스가 기술적 비효율 성과 부정적인 관련이 있는 중요한 요소임을 보여준다. 이 결과는 농민에게 생산성을 향상시키기 위해 신용을 제공하려는 정부의 노력 (SEMRY, UNVDA, ARFIC및 2세대 농업)과 일치한다. Agriculture is the mainstay of Cameroon economy as it serves the purpose of employment, food, and livelihood. However, Cameroon agriculture is plague by low productivity, inefficiency in production and dependent on imports. For this reason, this study examined the technical efficiency of rice farmers in Cameroon North-West region. Data were collected from 144 farmers using structured questionnaires and interview schedule. The Data was analyzed using descriptive statistics and a stochastic frontier analysis. The result from the stochastic frontier analysis shows that the variance parameters (sigma square and gamma) were statistically significant. The coefficient of farm size, fertilizers, labor and herbicides were positive and significant. The mean technical efficiency level was 84 percent implying that rice farmers’ technical efficiency could be increased by 16 percent if the available resources are efficiently utilized. The inefficiency model shows that credit access is the significant factor that is negatively related to technical inefficiency. This finding is in line with government efforts (SEMRY, UNVDA, CARFIC, and The Second Generation Agriculture) of providing credits to farmers to improve their productivity.

Purpose – An increase in the number of smartphone users and the availability of many phone brands has induced consumers to consider device features, the technology acceptance model (TAM), and switching barriers before making a purchase. As such, this paper seeks to investigate the factors (device features and switching barrier) and TAM determinants that influence the consumer satisfaction and purchase intention of smartphones. Additionally, we study the moderating effects that perceived ease of use may have on consumer purchase intention. Design/Methodology/Approach – To this end, the analysis of data (325) through structural equation modeling in AMOS seeks to examine the effect of device features, TAM determinants, and switching barriers on purchase intention. Findings – The findings demonstrate TAM (perceived usefulness) and device features (function and price) influence consumer satisfaction to varying degrees. With regards to switching barrier, switching cost has a positive influence on consumer satisfaction. Perceived ease of use moderates the relationship between device function and search intention. Finally, the study confirms the relationship between consumer satisfaction and purchase intention. Research Implications – Due to the importance of consumer satisfaction in forming purchase intention, companies should try to maximize the satisfaction of customers during interactions by providing device features that meet the need of the customer. Therefore, companies should try to identify the needs of customers. Going by TAM determinants, manufacturers have to ensure that the system technology of the smartphone is most useful for consumer day to day activities.
