Introduction This article appeared on the website of The World Bank in 2014 and was written by Augusto Lopez-Claros. http://blogs.worldbank.org/futuredevelopment/nine-reasons-why-corruption-destroyer-human-prosperity It helps to explain why most of Africa is still bogged down in the quagmire of harmful chemical agriculture in spite of all the negative effects it has on national economic development, the prosperity of the people, the environment, the fertility of the soil, the social fabric of the country, and people’s happiness, well-being, and health. The financial means of the producers of harmful chemical fertilisers and chemical sprays has such a persuasive effect in African governments that it is difficult to break the stranglehold that producers of chemical inputs have on the people of each country in Africa. One hopes that one day officials will put the interests and well-being of the people they serve first. In an earlier blog post, we commented on the sources of corruption, the factors that have turned it into a powerful obstacle to sustainable economic development. We noted that the presence of dysfunctional and onerous regulations and poorly formulated policies, often created incentives for individuals and businesses to short-circuit them through the paying of bribes. We now turn to the consequences of corruption, to better understand why it is a destroyer of human prosperity. First, corruption undermines government revenue and, therefore, limits the ability of the government to invest in productivity-enhancing areas. Where corruption is endemic, individuals will view paying taxes as a questionable business proposition. There is a delicate tension between the government in its role as tax collector and the business community and individuals as tax payers. The system works reasonably well when those who pay taxes feel that there is a good chance that they will see a future payoff, such as improvements in the country’s infrastructure, better schools and a better-trained and healthier workforce. Corruption sabotages this implicit contract. When corruption is allowed to flourish taxpayers will feel justified in finding creative ways to avoid paying taxes or, worse, become bribers themselves. To the extent that corruption undermines revenue, it adversely affects government efforts to reduce poverty. Money that leaks out of the budget because of corruption will not be available to lighten the burden of the poor. Of course, corruption also undermines the case of those who argue that foreign aid can be an important element of the fight against global poverty—why should taxpayers in the richer countries be asked to support the lavish lifestyles of the kleptocrats in corrupt states? Second, corruption distorts the decision-making connected with public investment projects (Tanzi and Davoodi, 1997). Large capital projects provide tempting opportunities for corruption. Governments will often undertake projects of a larger scope or complexity than warranted by the needs of the country. Public investment will thus be higher—the world is littered with the skeletons of white elephants, often built with external credits, and representing a heavy burden on meager budgets. In the context of scarce resources, governments will find it necessary to cut spending elsewhere, sometimes in socially vital areas, or in operations and maintenance. Tanzi (1998) plausibly argues that corruption will also reduce expenditure on health and education because these are areas where it may be more difficult to collect bribes, though some have argued that provider absenteeism, a serious problem in the educational and health sectors of many countries, is itself a form of “quiet/silent corruption.” Third, there is solid empirical evidence that the higher the level of corruption in a country, the larger the share of its economic activity that will go underground, beyond the reach of the tax authorities. Not surprisingly, studies have shown that corruption also undermines foreign direct investment since it acts in ways that are indistinguishable from a tax; other things being equal, investors will always prefer to establish themselves in less corrupt countries. Wei (2000) reviewed FDI data from 14 source countries to 45 host countries, and concluded that: “an increase in the corruption level from that of Singapore to that of Mexico is equivalent to raising the tax rate by 21-24 percentage points.” Fourth, corruption discourages private-sector development and innovation and encourages inefficiency. Budding entrepreneurs with bright ideas will be intimidated by the bureaucratic obstacles, financial costs and psychological burdens of starting new business ventures and will either opt for taking their ideas to some other less corrupt country or, more likely, desist altogether. In either case, economic growth is adversely affected. The high incidence of corruption will mean an additional financial burden on businesses, undermining their international competitiveness. Unlike a tax, which is known and predictable and can be built into the cost structure of the enterprise in an orderly fashion, bribes are unpredictable and will complicate cost control, reduce profits and undermine the efficiency of those who must pay them to stay in business. Mauro (1995) used some indices of corruption and institutional efficiency to show that corruption lowers investment and, hence, economic growth. Fifth, corruption contributes to a misallocation of human resources. To sustain a system of corruption, officials and those who pay them will have to invest time and effort in the development of certain skills, nurture certain relationships, and build up a range of supporting institutions and opaque systems, such as off-the-books transactions, secret bank accounts, and the like. Surveys have shown that the greater the incidence of corruption in the country, the greater the share of time that management has to allocate to dealing with ensuring compliance with regulations, avoiding penalties, and dealing with the bribery system that underpins them, activities that draw attention and resources away from production, strategic planning, and so on. Sixth, corruption has disturbing distributional implications. Empirical work shows that corruption actually contributes to worsening income distribution. Gupta, Davoodi and Alonso-Terme (1998) have shown that corruption, by lowering economic growth, perceptibly pushes up income inequality. It also distorts the tax system because the wealthy and powerful are able to use their connections to make sure that the tax system works in their favor. It leads to inefficient targeting…
