Aid for trade in action.
Aid for trade aims to help overcome the constraints that inhibit the ability to benefit from market access, development, creation of jobs, poverty eradication, growth, empowerment of communities and gender participation.

The G.I BILL is well known to be the cause of prosperity, the 1920’s was a period of economic prosperity innovations and products were developed quite in number, consumers received these products on time, no government was willing to  put too much regulation  on investors for the reason of fear to upset the economic boom.
Today industrial practices are regulated by governments and consumer purchase is no longer masked by the use of installment.
The analysis on competitiveness, effort on the increase of security in the sub-Saharan Africa, effort of increase of population education and the effort for the increase of foreign investment has increased at very least; they are the measures of growth and economic prosperity in the sub-Saharan Africa.

The gross domestic products measures and conclude the result on economic progress whether it is rising and the nation is moving forward, more countries in the sub-Saharan Africa are identified by the fall of their economies caused by insecurity, low education among its people and lack of strategies to attract  investors; life condition measured by GDP is not part of our measures in this study, but the genuine progress indicator created in 1995 is an alternative to the traditional GDP measure of sub-Saharan Africa economic prosperity.
The genuine progress indicator reveals that, the consumer confidence is part of what causes economic prosperity in the Sub-Saharan Africa, in many places businesses continue to grow but appearances seems to indicate slowdown in site, governments in the Sub-Saharan Africa seem to be willing to introduce too much regulation as compliment to revenue collection but they don’t fear to upset the economic boom that may occur, so the Sub-Saharan Africa has a chance to make this era to be the era of growth and economic prosperity by restoring consumers’ confidence and regulate regulation for the favor of investors  and regulate  industrial practices to a great extent.
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.
