Corruption involves dishonest conduct by people in positions of authority to gain personal benefits. It can occur on different scales from petty to grand. Common forms of corruption include bribery, embezzlement, theft, and fraud. Corruption negatively impacts social and economic development by diverting investment and weakening public institutions like education and healthcare. It undermines democracy and exacerbates inequality. Personal greed, low salaries, lack of transparency and accountability in regulations and processes all contribute to corruption.
