    Factors affecting fertility choice among married couples in Oton, Iloilo
    Autentico, Sheila M.; Cagalagawan, Aiza Maris G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2008-03)
    The study identified the different factors affecting fertility choice of married couples in Oton, Iloilo. There were 100 participants from the three barangays in Oton. Iloilo namely: Trapiche, Poblacion South, and Buray. The dependent variable is measured by the actual number of living children the married couples have. The independent variables were classified into four categories: economic factors, biological factors, psychological factors, and geographical factors. The multivariate analysis revealed that the significant variables found to significantly affect the decision on the number of children by married couples (at 5% level of significance) are gross monthly income of the household, years of formal education of the wife, age of wife at first marriage, ideal number of children by the couple and perception of children to be of help in old age. However, the R-squared value of 30.78 indicates that there are still some factors that were not included in the model. Nevertheless, the significant variables had the expected signs.

    Willingness-to-pay for the conservation of mangrove site in Dumangas, Iloilo
    Agapito, Arianne I.; Guadalupe, Ronell D. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    This study was designed to determine the willingness-to-pay of the residents of Dumangas, Iloilo for the conservation of the existing mangrove sites in their area. Data were gathered through personal interviews using an interview schedule among 240 household representatives equally distributed in six barangays: three coastal, three noncoastal. Results of the study showed that most of the study participants were aware and knowledgeable about the existence of mangroves, its uses and benefits. The popular barangays identified to have mangrove sites included Sapao (31.33%) and Ermita (32.92%). Using dichotomous choice willingness-to-pay method with randomly assigned bid prices, results showed that most of the study participants both from coastal (89.17%) and non-coastal barangays (91.67%) were willing to pay for the conservation of mangroves. The main reason cited was that they want to participate in programs by the local government that aims to conserve the environment. When adjusted to level of certainty, there was slight difference in the number of study participants who were willing-to-pay; mean willingness-to-pay amounted to Php 86.47 without adjustment to level of certainty and Php 76.17 when adjusted to level of certainty. Knowledge index rating, civil status and bid price were the significant factors that affect the willingness-to- pay without adjustment to level of certainty at 5% level of significance. When adjusted to level of certainty, knowledge index rating (5%) and bid price (1%) were the significant factors. Annual surcharge in Community Tax is the preferred payment vehicle of the study participants for the conservation.

    Value chain analysis of sergestid shrimp (Acetes Spp.) in Oton and Tigbauan, Iloilo
    Andres, Junaelle Kyla B.; Iguban, Myra Marie B. (Division of Social Sciences, College of Arts and Science, University of the Philippines Visayas, 2014-04)
    The sergestid shrimp industry in the municipalities of Oton and Tigbauan has contributed to income and employment of the local shrimp catchers, traders, and processors. This study described and analyzed the value chain of sergestid shrimp in these municipalities. Specifically, the study described the market actors, their marketing practices, and the value chain; determined the revenues received, costs incurred, and gross margins received by the market actors; identified roles performed by the men and women in the sergestid shrimp value chain; and identified the problems facing the market actors. Data were collected from personal interviews of 14 shrimp catchers, 9 raw shrimp traders, 11 shrimp processors, and one shrimp product trader. The shrimp catchers caught an estimated 132,758 kilograms of shrimp in a year. Most were sold (129,182 kilograms, 97.31%), with only the three commission houses handling an estimated 128,702 kilograms (96.94%). The major outlets of the commission houses included raw shrimp retailers and different types of shrimp processors. The highest average selling price (P372.73/kg), gross margin (P168.65/kg), and net returns (P161.39/kg) was received by one shrimp product retailer. Generally, the shrimp catchers were price takers, with the commission people as quantity leaders and seemingly price leaders. The net added value of shrimp increases as it is transformed into new forms such as the shrimp paste, dried shrimp, and shrimp mill. The men performed more strenuous roles (such as catching, hauling, and loading shrimp) while the women performed more time-consuming roles (buying inputs in catching or processing and selling). Adding value to the raw shrimp through processing can increase returns. Creative ways to create demand for raw and processed shrimp should be introduced. New processing technology, new market outlets for processed shrimps, and better packaging can increase demand for processed shrimp. With more players in the market, price can be set by more players.
