in contrast to foreign demand, a huge domestic demand impede an increase of the export related by ADB (2005), which reported a negative association between exports ahd growth rate of domestic demand in the southeast Asian countries. thus a variation in domestic demand pressure will affect the supply-side or availability for export. ball et.al (1966) also argued that at relatively high level of domestic demand the surplus production leads to increased export volume.He further said that higher level of domestic demand the surplus prduction leads to increased exportvolume. He further said that higher level of domestic demand,ceterus paribus, the quantity of resources devoted to export is lower. so, at lower domestic demand the surplus production leads to increased export volume. He further said that higher level of production is the main cause of rxpoet expansion since surplus output can be exhausted in internsational markrts.Ngeno(1990) carried out a study on determinants of export and one of his findings was that export is positively related to output level since higher production leads to increased volume of export,and finds that export is associated with high volume exportedand and not high price for the product.
