Short Take

Shining a Light on the Development Supply Chain

Chris Tang and fellow field researchers constructed a model to subsidize essential goods for low-income communities in crisis, and profit in recovery

If you're in the business of providing financial aid to help poor communities obtain basic living needs, a core consideration is how to score the biggest social bang for your buck.

A real-world case study played out in Haiti, in the aftermath of its devastating 2010 earthquake. With the power grid decimated, distribution of subsidized solar-powered lanterns was pursued as a way to aid recovery and development. In field research conducted between 2014 and 2016, James Knuckles and ManMohan Sodhi of City University, London, UCLA Anderson's Christopher Tang and Jiayi Yu of Tsinghua University, Beijing, found no consensus among the aid organizations (e.g., World Bank and USAID), impact funds (e.g., Kiva), manufacturers (e.g., d.light) and retailers involved in the Haiti solar lantern initiative as to the best way to target the subsidy.

That led the researchers to construct a model to ferret out the best use of donor dollars along the "development supply chain." Unlike a traditional commercial supply chain that is solely focused on profit, a development supply chain is a bridge between humanitarian aid that flows in the immediate aftermath of a crisis, and a post-recovery market economy in which basic needs are met without aid.

While effective deployment of funds during this interim period is the main focus of aid, an ancillary consideration is the extent to which the program might help (or hinder) an eventual segue to a purely commercial supply chain model once the economy recovers.

Subsidizing manufacturers is suboptimal. There's no guarantee a subsidy would be poured into more R&D in the hopes of leading to a permanent reduction in production costs that could be passed along.

Instead of subsidizing manufacturers, the researchers determined that donors such as the World Bank and USAID should focus more on how to direct development and recovery subsidies into the distribution channel.

It turns out that some basic tenets of capitalism work best for selling subsidized essential goods in low income communities. Rather than simply flood the retail market with a single subsidized product, the authors determined that "choice is good." Giving the consumer the ability to make a conscious choice of subsidized Lantern A over subsidized Lantern B increases demand - as does giving the consumer the ability to choose among different retailers offering more than one product.

The fact that no single distributor — or product — dominates in this structure is an important feature. "The donor can rest assured that acting optimally would still leave positive profits for retailer micro-entrepreneurs," wrote the authors. "And, in the long term, doing so sets the stage for subsidy-free development with commercial supply chains."

Edward W. Carter Chair in Business Administration

Chris Tang’s early research focused on mainstream operations management problems, such as production planning and control, inventory models with yield uncertainties, design and control of flexible manufacturing lines, and capacity configuration problems. It now spans areas that include global supply chain management, retail operations and social business operations. His current interest focuses on social innovation for developing countries, looking at ways that companies can operate in the environment, doing good and doing well at the same time.
