Relation of Transparency and Economic growth is a long global debate in the society. Theoretically, policy makers, scholars and researchers argue that there is a close relation among these two variables. However, the quantitative relation and any global model is yet unrevealed. So, the main aim of this paper is to ascertain the nature, dimension and extent of the relationship between economy and Transparency as well as to invent a global model. This paper is useful for researchers, planners, policy makers and scholars who are directly or indirectly involved or willing to involve in the thrust for quantitative relation of these two variables. Literature review is the main source of information of this study. In introductory section, this paper briefly describes theoretical relationship of economy and Transparency as well as it also describes the proxy variables.GDP (2012) of different countries are used as proxy of Economy and Corruption Perception Index (CPI) scores (2012) of different countries are used as proxy of level of Transparency. In methodology section this paper describes the detail methodology, sampling procedure and level of analysis. This study randomly selects 30 countries (10 from higher CPI scores+10 from moderate CPI scores+ 10 from lower CPI scores) around the globe as sample. In the third section, this research presents the correlation value which divulge that there is a positive correlation (p=.047) with 95% confidence level. That reveals, if the level of transparency of any country increase, the GDP also increase accordingly. Then in this section two quantitative models are developed using linear regression analysis. First invented model is: Economy (GDP in billion US$) = [(8.983*Level of transparency) -108.11]. This paper termed the first invented model as “Mahmud EcoT Model-1”. This model calibrates that one unit improvement of transparency leads 8.98 billion US$ improvement in the GDP of a country. Then taking this unit change proportion, this research concoct second model for prediction purpose. The second invented model is: Predicted GDP in billion US$ of a country=Present GDP of the country +8.98*Targeted level of transparency improvement .The second invented model is termed in this research as “Mahmud EcoT Model-2”. This model is applicable for any country around the globe for prediction of economic growth according to the targeted Transparency level. In the last section, this paper briefly describes the application of the “Mahmud EcoT Model-2” taking Bangladesh and Romania as two case countries.
