Abstract: Liwanag, Ma. Cristina Hondo. "Supply Analysis of Mangosteen in the Philippines", B. S. Thesis, Bachelor of Science in Business Management major in Marketing, Cavite State University, Indang, Cavite, April 1998, Adviser: Dr. Alice T. Valerio. This study was conducted primarily to analyze the supply of mangosteen in the Philippines. Specifically, it aimed to describe the mangosteen industry in the Philippines; identify the factors affecting the supply of mangosteen; and ascertain the regional contribution of mangosteen in terms of production and area planted. Secondary data from 1980 to 1995 were used in this study. Data were obtained from the Bureau of Agricultural Statistics (BAS), Fertilizer and Pesticide Authority (FPA), Department of Agriculture (DA), National Statistics office (NSO) and PCARRD. Data were analyzed using trend analysis, multiple regression and F-test with the aid of micro stat software. In addition, the basic formula for the coefficient of price elasticity of supply in linear form was also used to explain the responsiveness of the supply of mangosteen with regards to its price and price of its competing crop. Results of the trend analysis showed that throughout the whole period, the area planted to mangosteen has increased at an average growth rate of 12.54 percent. Western Mindanao had the highest production and area planted to mangosteen followed by Southern Mindanao, Northern Mindanao, and Central Mindanao while the lowest production and area planted to mangosteen was in Western Visayas. The government policy which was assumed to have an effect on the mangosteen industry was the Comprehensive Agrarian Reform Law (RA 665). This law restricted the expansion of different industries and required agricultural corporations to distribute three percent of their income to the farm workers. Using the multiple regression analysis, it was found that the supply of mangosteen was not affected by the price of rambutan, price of fertilizer, dummy policy, and tropical cyclones. Supply of mangosteen was significantly affected by its own price, farm wage rate and area planted. The coefficient of determination (R2) of 0.93 implies that 93 percent of the total variation in the supply of mangosteen was explained by the independent variables in the model. Results of the analysis of the area response function showed that area planted to mangosteen was significantly affected by farm wage rate and quantity supply of mangosteen. However, it was not influenced by the price of fertilizer, price of rambutan, price of mangosteen, government policy and tropical cyclones. With regards to the coefficient of price elasticity of supply in linear form, it was found that supply of mangosteen is inelastic with its own price which has a value of 0.42. The identified independent variables that are significantly related to the supply of mangosteen were price of mangosteen, farm wage rate and area planted to mangosteen. Supply of mangosteen was not affected by the price of rambutan, price of fertilizer, dummy policy, and tropical cyclones. For the area response function, results showed that area planted to mangosteen was significantly affected by the farm wage rate and quantity supplied of mangosteen and it is not related to the price of fertilizer, price of rambutan, price of mangosteen, dummy policy, a
