Violence between individuals 'kills nine times more people' than wars

CONFLICT AND VIOLENCE
There is an ongoing debate on what has brought about the reduction in violence over the past three decades in high income countries, but the phenomenon cannot be reduced to the application of a few societal programs. Attitudes to violence typically change slowly over time; examples are wife beating and corporate punishment of children. Programs aimed at reducing violence are thus unlikely to produce results quickly. In addition, many programs have not been set up in a manner allowing rigorous evaluation. For many of these interventions we neither know their impact nor do we know their costs, thus making it impossible to provide BCRs.
Despite the uncertainty of what feasible targets for violence reduction are and how they can be achieved, we advocate the inclusion of such targets in the post-2015 agenda. Our estimates suggest that the costs of violence are high; the welfare cost of collective, interpersonal violence, harsh child discipline, intimate partner violence and sexual abuse are equivalent to around 11 per cent of global GDP. The cost of homicides are much larger than the cost of civil conflict. However, violence perpetrated in the home appears to be the most prevalent form of violence. Domestic abuse of women and children should no longer be regarded as a private matter but a public health concern.
Summary of the most high-yielding targets from the paper
|Conflict and Violence Targets||Benefit for Every Dollar Spent|
|Eliminate severe physical violence as a method of child discipline.||$11|
|By 2030, reduce the number of countries experiencing large scale wars (1000+ deaths) to 3 or fewer and the
number of countries experiencing small scale wars (>1000 deaths) to 14.
|Improve Policing.||Likely To Be High|
|Eliminate all forms of violence against women and girls.||Likely To Be High|
Summary of the cost estimates

Anke Hoeffler, Research Officer at Oxford, and James Fearon, Professor of Political Science at Stanford University, break new ground in estimating the global costs of violence and conflict in an Assessment Paper for the Post-2015 Consensus. The paper shows that the costs of collective, interpersonal violence, harsh child discipline, intimate partner violence and sexual abuse represent 11% of worldwide GDP. Interestingly, the types of violence that are most costly to society are ones that tend to attract less attention, in both development spending and public imagination. Violence in the home is 6.5 times more costly than homicide, and 50 times more costly than civil war. The paper does not offer definitive benefit-cost ratios for targets, pointing to scant evidence with which to base assessments. Nevertheless, the authors strongly recommend that targets to address violence should be included in the final post-2015 list.
We argue for moving beyond a near-exclusive focus on civil war violence … to recognizing that the costs of interpersonal violence are probably much larger but are almost wholly neglected in current development programming."

S. Brock Blomberg, Professor of Economics and Finance at Claremont McKenna College, commends the effort of the assessment paper authors in cataloguing various forms of violence, their costs and the benefits of existing programs. However, he argues that the inability to derive benefit-cost assessments is a notable weakness of their analysis and attempts to fill this gap. He suggests targets to curb violence on a global basis are likely to have small benefits for every dollar spent.
I find that most of the policies being evaluated in [the assessment paper] are most likely to have modest impact with little evidence that these policies implemented in a manner that would be exceptional.”
- S. Brock Blomberg
Rodrigo R. Soares, Professor of Economics at the Sao Paulo School of Economics, sympathizes with the challenges the assessment paper authors have in providing benefit-cost ratios for targets. Extrapolating studies outside of the original context is risky. Instead, the discussion would benefit from a slightly different perspective, taking a further step back to define specific issues of paramount importance together with promising interventions. Under these criteria, the focus should be on common crime, rather than civil conflict or violence against women and children.
While common crime and violence seem to be closely connected to socioeconomic conditions and state policies in the area of public security, violence against women and children usually have more of a cultural nature, and therefore would require other types of policies.”
- Rodrigo R. Soares
The viewpoint of Abigail E. Ruane, Peace Women Program Manager at Women’s International League for Peace and Freedom, finds that the assessment paper provides a revealing evaluation of the costs of violence and the need for a violence prevention approach to development. However, Ruane states that the arguments in the paper are based on very conservative economic benefit-cost assessment of general trends. Instead, in Ruane’s view, a more promising means of reducing violence would be to take a holistic approach to strengthening the participation, protection, and rights of women and other at-risk groups across the conflict spectrum to prevent the root causes of violence and conflict.
As the next development agenda is designed, policymakers should take to heart Fearon and Hoeffler’s call for a violence-prevention approach to development that addresses all forms of violence, not just violence in conflict."
- Abigail E. Ruane
The authors paint a robust picture of the scale for both interpersonal violence and collective violence. They make a strong case for why the international community should widen their focus beyond civil war to include targets for reduced homicide, domestic violence, and other forms of societal violence in the post-2015 development agenda."- Ciara Aucoin and Olivia Russell
Overall, the viewpoint of Charles Ransford, Director of Science and Policy at Cure Violence, agrees with the authors - that violence reduction is crucial to economic and social development. However, Ransford’s view is that the analysis provided in the paper is imperfect and likely underestimates the problem, but even this underestimate shows that violence is a huge cost to society and warrants prioritization. According to Ransford, violence greatly impedes the world’s ability to address almost all the issues that have traditionally been identified as underlying causes of violence. If we focus more resources on interrupting and stopping the spread of violence, not only will we have less violence, but we will significantly increase the potential of success for interventions that address the underlying causes of violence.
"We see a great opportunity to take on violence and make a big impact that will not only affect violence but will have a ripple effect in many other areas."
- Charles Ransford
The Post-2015 Consensus project brings together 60 teams of economists with NGOs, international agencies and businesses to identify the targets with the greatest benefit-to-cost ratio for the UN's post-2015 development goals.
