CORRUPTION IN NIGERIA: A THREAT TO SUSTAINABLE ECONOMIC DEVELOPMENT
 INTRODUCTION 
  Amuwo  (2005) and Obayelu (2007) consider corruption as the exploitation of public  position, resources and power for private gain. Fjeldstad&Isaksen (2008, p.  3) and Ogundiya (2009, p. 5) define corruption as “the betrayal of public trust  for individual or sectional gain.” Obayelu went further to identify corruption  as “efforts to secure wealth or power through illegal means for private gain at  public expense; or a misuse of power for private benefit.” Corruption covers a  broad spectrum of activities ranging from fraud (theft through  misrepresentation), embezzlement (misappropriation of corporate or public  funds) to bribery (payments made in order to gain an advantage or to avoid a  disadvantage). From a political point of view, Aiyede (2006, p. 5) views corruption  as “the abuse or misuse of public or governmental power for illegitimate  private advantages.” His view corroborates the position of Lipset and Lenz  (2000) that corruption is an effort to secure wealth or power through illegal  means for private benefit at public expense. Tanzi (1998) adds that such abuse  of public power may not necessarily be for one’s private benefit but for the  benefit of one’s party, class, tribe, or family. Although corruption is global  in scope, it is more pronounced in developing societies because of their weak  institutions. It is minimal in developed nations because of existing  institutional control mechanisms which are more developed and effective.
