Wiwatchai Kruatreepradit
Lagged farm price elasticity of domestic supply of pig was 0.13 and the elasticity of domestic supply caused by number of sow and average cost of production was 0.72 and 0.32 respectively that meant the lagged farm price, number of sow and average cost of production changed one percent, the domestic supply of pig would be changed 0.13, 0.72 and 0.32 percent respectively. The elasticity of wholesale price of pig at the Bangkok market generated by the change of slaughtered price of pig at the Bangkok market was 0.51 and the elasticity of pig price received by farmer due to the change in wholesale price of pig at the Bangkok market was 0.68. The increasing number of sow 20 percent caused the domestic supply increased by 14.10 percent slaughtered price at the Bangkok, wholesale price at the Bangkok market and farm price of pig increased by 4.54, 2.30 and 0.06 percent respectively, the domestic demand of pig decreased 3.38 percent by average. The study on effects by increasing per capita income 20 percent caused the domestic supply, domestic demand, slaughtered price at the Bangkok market and farm price of pig increased by 14.10, 7.46, 4.76 and 0.06 percent respectively, wholesale price of pig at the Bangkok market decreased 0.05 percent by average. Domestic demand and supply of pig would be at the average of 10,580,150 and 7,492,560 heads/annual and the price of pig in the Bangkok market and farm gate would be at the average of 26.63, 23.30 and 22.44 baht per kilogram per year respectively.
