Till Bruckner worked for NGOs in Georgia and Afghanistan before managing Transparency International's Georgia’s aid monitoring programme in 2008-2009. He writes in Aid Watch: Just Asking That Aid Benefit The Poor about Secret NGO Budgets.
Are you ashamed of your organization’s budgets? Do you think your supporters would be shocked if they could see exactly how you are spending their money? Do you feel the need to keep your finances hidden from your local partners and clients? If you answered all three questions with “yes,” you might be working for an international NGO.
Bruckner also writes at NGO Watch, "How Corrupt Is The World Food Program?"
Private donors in wealthy countries simply lack the information needed to hold aid and development NGOs to account for how their donations are used thousands of miles away. The only information available is that which is voluntarily provided by the NGOs, which are extremely reluctant to open their operations to scrutiny....
Institutional donors like USAID usually do have a presence on the ground in developing countries, but they rarely directly monitor NGO activities in the field. Instead, they usually, though not always, rely on information provided by their grantees. Interviews with dozens of donor and NGO representatives in Georgia, Afghanistan, and Tajikistan suggest that neither NGOs nor donor country offices have an incentive to document instances in which aid money is stolen, wasted, or unwisely spent. Projects are almost invariably portrayed as successful, irrespective of realities on the ground....
Aid organizations have responded to concerns about their lack of accountability through a variety of initiatives and mechanisms intended to create transparency within the aid community. Senior staff members at NGOs’ global headquarters readily sign up to noble-sounding initiatives and commit their organizations to meeting certain standards. But these measures lack teeth and often require organizations to act as a whistleblower against a partner agency. As a result, they are almost universally ignored in practice.
A respondent to Bruckner's top piece says he's afraid to alarm the natives:
Although open accounting can seem like a good practice, it is very tricky in poor countries. I have been running international projects for twenty years. The rent on my house is higher than the salary of many of my staff. My salary is nearly triple the highest local salary. Additionally, my top staff is paid well–many times more than what our beneficiaries receive. I think that telling our beneficiaries how much we earn would reinforce the gap between them and us. It would also complicate relations with our government partners (who earn less). I am always happy to share general information about costs (our program in the Haitian-Dominican borderlands is around $650,000/year), but see little upside to sharing details.
I bet he votes Democrat.
