According to a recent update from the World Health Organization (WHO) the Ebola Virus outbreak, believed to have originated in Guinea in December of last year, has infected more than 5,800 people and claimed 2,793 lives so far. With a death rate of 70%, WHO researchers issued a dire new forecast this week, one that anticipates 20,000 deaths by November (10,000 in Liberia alone). The urgency of the issue has been clear for months now, but it has only recently begun to pick up traction and illicit international response in which aid commitments have been stepped up. Why has it taken this long? How is there still no effective and widely accessible vaccine for Ebola? Well, it probably has something to do with market failure.

Despite a widespread tone of moral indignation towards “Big Pharma” companies, which have essentially monopolized the commercial vaccine supply, the fact remains that there is a lack of profitability from a big market and thus a lack of incentive to produce for those who need it most. This clearly constitutes a market failure whereby the market underprovides a good, which has the potential for vast public benefits. The economic incentives (profits) for the production of these vaccines fall short of public health needs. Yet, if there were to be intervention in the market, which would encourage producers to supply closer to the socially optimal level, demand would be met and the epidemic could be contained. The figure below illustrates the forecast of three different scenarios as predicted by a research team at Columbia University further elucidating the urgency of the matter even in a best-case scenario:
The private benefit of getting the vaccine would be less than the marginal social or public benefit and thus carries with it positive spillover, which goes beyond the obvious health benefits. Said public benefit would not only consist of the lives saved throughout the region by the containment of the virus, but also the prevention of complete economic downturn and further hardship. Strict trade and travel restrictions have already dampened West African economies, but if Ebola is not controlled soon, the World Bank estimates that the long-term effects will be crippling. At its current rate, the virus would cause Liberia’s economy to contract by 4.9% and reduce economic growth in Sierra Leone from 11% to approximately 2%.
It is disillusioning to see that the moral imperative to help those suffering is far weaker than that of the profit incentive. It has been almost 40 years since Ebola was discovered in 1976, yet there is still no cure, despite its medical feasibility. The alignment of incentives is crucial in order to correct for the shortage of a widely accessible and effective drug in the market.
Bottom Line: The Ebola virus has spun out of control and now, the necessity of multi-lateral action is more pressing than ever.
