Corruption also undermines economic development by generating considerable distortions and inefficiency. In the private sector, corruption increases the cost of business through the price of illicit payments themselves, the management cost of negotiating with officials, and the risk of breached agreements or detection. Although some claim corruption reduces costs by cutting red tape, the availability of bribes can also induce officials to contrive new rules and delays. Openly removing costly and lengthy regulations are better than covertly allowing them to be bypassed by using bribes. Where corruption inflates the cost of business, it also distorts the playing field, shielding firms with connections from competition and thereby sustaining inefficient firms.
Corruption also generates economic distortions in the public sector by diverting public investment into capital projects where bribes and kickbacks are more plentiful. Officials may increase the technical complexity of public sector projects to conceal or pave way for such dealings, thus further distorting investment. Corruption also lowers compliance with construction, environmental, or other regulations, reduces the quality of government services and infrastructure, and increases budgetary pressures on government.
Economists argue that one of the factors behind the differing economic development in Africa and Asia is that in the former, corruption has primarily taken the form of rent extraction with the resulting financial capital moved overseas rather invested at home (hence the stereotypical, but sadly often accurate, image of African dictators having Swiss bank accounts). University of Massachusetts researchers estimated that from 1970 to 1996, capital flight from 30 sub-Saharan countries totaled $187bn, exceeding those nations’ external debts. (The results, expressed in retarded or suppressed development, have been modeled in theory by economist Mancur Olson.) In the case of Africa, one of the factors for this behavior was political instability, and the fact that new governments often confiscated previous government’s corruptly-obtained assets. This encouraged officials to stash their wealth abroad, out of reach of any future expropriation. In contrast, corrupt administrations in Asia like Suharto’s have often taken a cut on everything (requiring bribes), but otherwise provided more of the conditions for development, through infrastructure investment, law and order, etc.
