Growth and dynamics of world trade on consumers in the East Africa Community market.
By the founding of the German Zollvere in 1834 several customs unions were successfully launched followed by the European union in 1958, no customs is levied on goods transported within the union, they impose common external tariff on all goods exported to the union, this has increased the economic growth and development though the redistribution of revenue which can not be discussed but no partner state has so far excluded itself from the union rather emerging issues have been noted and challenges have been addressed. East Africa community implemented customs union in 2005 with determination to be progressive, they have reached stages of development and comparative advantage in some commodities and determined to reduce imbalances to foster and encourage accelerated and sustained development of the community. Trade policy of partner states in the East Africa customs union contributes to shocks and increase of competition, derogation in the customs union does not favor other partner states to grow and increase investment for the intra-regional trade, common external tariff has increased investment of the world access into the East Africa community market, the customs union has created growth, it has created trade and it has diverted trade, this has reliantly showed positive and negative effect on consumers preference and on consumers price.
It is investigated that Growth in investment of the world trade to the East Africa Community markets has changed trade value and quantity on top ten ranked primary products traded into the East Africa Community if you compare trade before the customs union and after the customs union, two partner states of the East Africa community among the five have noted growth, and the three have not for the past three years. Those who were trading at bilateral trade and preferential rate of less than the applied common external tariff increased investment by trading products of less quality to maintain the market, and others have diverted the East Africa Community market because they did not compromise to produce products of less quality, product differentiation either homogeneous or exogenous has caused competition, business environment has not changed to the fact that it did not affect the market. So to join the customs union countries need review their trade policy to be beneficial in the customs union and favor local manufacturers/ industry from competition and let there be no effect on consumer demand, price and quality.
