Resilience to Avoid and Escape Chronic Poverty:
Theoretical Foundations and Measurement Principles Christopher B. Barrett and Mark A. Constas
Cornell University December 11, 2012 presentation at CARE USA’s Washington, DC, Roundtable on Resilience
Prologue
Activity – past few years
Three main reasons for increased activity around the concept of development resilience 1. Pronounced Risks
Increasing exposure to risk related to natural disasters, climate, food markets, macroeconomic shocks, political violence, etc.
2. Bridging the Divide
Recurring crises have highlighted the importance of aligning humanitarian and development objectives
3. Ecological/biophysical Factors
Growing consensus that development work must be connected to pressing environmental concerns
Prologue
Activity – past few years
• • •
Work concerned with the poverty dynamics is not new, but the recent activity in development has used resilience as a common platform on which: A range of initiatives, strategic plans, and funded program for humanitarian response and development assistance have been based Broad participation from government agencies, INGOs, multilateral organizations and foundations has been structured and promoted Many white papers, reports, workshops, conferences, newly established centers, working groups, high profile events, articles, blogs, and tweet… have been based

I. Framing the Problem
What do we have and what is needed?
• • •
What we have:
Much activity/enthusiasm around the resilience concept Some activity is rhetorical, some is strategic/policy oriented, some is conceptual, and some is programmatic An opportunity to bridge between humanitarian response and development assistance strategies • • •
What we need:
Theory to integrate programmatic efforts and analytical approaches connected to mitigation, buffering, coping, and adaptation Theory-driven measurement to evaluate progress Body of empirical results based on theory-driven measures
I. Framing the Problem
Call for Theory of Resilience
• •
Theory is important because it:
Serves as a conceptual tool to help build coherence for wide range of variables and across a selection of programmatic approaches Directs attention to the importance of explanations that identify not just if something worked but also why something worked –thereby pushing us to identify causal mechanisms
Highlighting the need for explanatory knowledge of resilience , a recent ODI Humanitarian Policy Brief offered the following:
“…the frameworks [of resilience cannot assist in answering critical questions, such as what is it that makes people more or less sensitive to crisis, because these dimensions are left as unexplained ‘black boxes’ ”(Levine et al., 2012, p. 2).

II. Toward a Theory
Resilience foregrounds risk in well-being dynamics:
Shocks that disrupt lives and livelihoods: the single greatest cause of descents into chronic poverty (Krishna, etc.) Uninsured risk of catastrophic loss (stressors): a key structural reason for poverty traps/chronic poverty We seek to bridge the ecological/engineering literatures on resilience with the social science literatures on risk and poverty traps in order to: - advance a theory of resilience against chronic poverty - tease out measurement principles appropriate to that theory
Resilience of whom to what?
II. Toward a Theory
Subject of interest – quality of life, roughly Sen’s ‘capabilities’. This implies a focus on individuals’ (and groups’) well-being within a system, not the state of a system itself. System has instrumental rather than intrinsic importance.
Focus further on minimizing the human experience of chronic poverty. We therefore focus on places with high rates of chronic poverty and risk exposure.
Do not focus on a specific source of risk b/c problem is uninsured exposure to a wide array of stressors (ex ante risk) and shocks (ex post, adverse realizations) to which resilience implies adaptability while staying non-poor.
II. Toward a Theory
We need to adapt ecological/engineering theory to the development/humanitarian response context. As used in ecology or engineering – e.g., “the ability of the system to maintain its identity in the face of internal change and external shocks and disturbances” (Cumming et al. 2005 Ecosystems, p. 976) – resilience is not necessarily desirable for populations trapped in chronic poverty. Their objective may be escape from – not persistence in -- their present state of existence.
To be useful for development policy, we need resilience to be a normative property, to be orderable – and preferably decomposable (in FGT sense) – in order to offer a useful metric to gauge performance and guide policy/programming.
II. Toward a Theory
Concept of Resilience for Development
Development resilience represents the likelihood over time of a person, household or other unit not being poor in the face of various stressors and in the wake of myriad shocks. If and only if that likelihood is high, then the unit is resilient.
Key Elements:
Standards of living: Focus on avoiding/escaping poverty Effects of stressors: Uninsured risk influences dynamic incentives Response to shocks: Temporary setbacks vs. permanent descents Dynamical system vs. static representations of standards of living
II. Toward a Theory
Well-Being Dynamics
Figure 1: Nonlinear expected well-being dynamics with multiple stable states E[future] capabilities Chronic poverty zone Non-poor zone Current Death capabilities Death T1 T2
Noncontroversially: NPZ >> CPZ >> HEZ Those in CPZ or HEZ are chronically poor in expectation The CEF reflects indiv/collective behaviors (agency/power) w/n system
II. Toward a Theory
Well-Being Dynamics
Figure 1: Nonlinear expected well-being dynamics with multiple stable states E[future] capabilities
The development ambition is to move people into the non-poor zone and keep them there. The humanitarian ambition is to keep people from falling into HEZ … offers foundation of a rights based approach to resilience.
Death Death Chronic poverty zone Non-poor zone Current capabilities
For the current non-poor, seek ‘resilience’ against shocks in the ecological sense: no shift to either of the lower, less desirable zones.
But for the current poor, those in HEZ/CPZ, the objective is productive disruption, to shift states.
Asymmetry is therefore a fundamental property of resilience against chronic poverty. Thus stability ≠ resilience.
II. Toward a Theory
Well-Being Dynamics
A Utopian, asymmetric vision of well-being dynamics: Figure 2: Desired expected well-being dynamics with multiple stable states E[future] capabilities Egalitarian option Chronic poverty zone Non-poor zone Death Death Current capabilities
‘Egalitarian option’: engineering concept applies - return to initial state. ‘Random walk w/safety net option’: implies perfect downward resilience at NPZ/CPZ boundary … but zero resilience upward or w/n NPZ.
II. Toward a Theory
Well-Being Dynamics
Explicitly incorporate risk, move from CEF to CTD: Figure 3: Nonlinear well-being dynamics with conditional transition distributions Future capabilities Chronic poverty zone Non-poor zone Death Current Death capabilities
Note: The shape of the CTD affects the shape of the CEF Transitory shocks (- or +) can have persistent effects Risk may be partly endogenous to system state
II. Toward a Theory
Well-Being Dynamics
Feedback between sub-systems can be crucial
If we represent the preceding conditional transitions as: W t+1 =g(W t |R t ,ε t ) where W is welfare, R is the state of the natural resource, and ε is an exogenous stochastic driver Then simply introducing feedback between R and W (e.g., range conditions depend on herd size/stocking rate) R t+1 =h(R t |W t ,ε t ) or allowing for drift in ε (e.g., due to climate change) means the underlying CTD changes over time.
Then the resilience of the underlying resource base becomes instrumentally important to resilience against chronic poverty.
II. Toward a Theory
Well-Being Dynamics
Coupled human and natural systems dynamics E[future] capabilities ?
E[future] natural resource state Current capabilities
Note:
Current natural resource state
- Ecological resilience links to human resilience through reciprocal causality in coupled human/natural dynamics - Many candidate relationships make prediction difficult at best
II. Toward a Theory
Programming implications
Objective: min likelihood people fall into HEZ/CPZ Three options:
1) Shift people’s current state – i.e., move initial state rightward. Ex: asset transfers: cash, education, land.
2) Alter CTDs directly (and thereby ∆ system too). Ex: social protection - EGS, insurance, improved police protection, drought-resistant animal/plant genetics. 3) Change the underlying system structure – institutions/ technologies – induces ∆ in behaviors and CTDs. Prob: multi-scalar reinforcement – ‘fractal poverty traps’ Systems thinking becomes important to reveal the structure – and possible intervention points – behind univariate dynamics.

Programming implications
The importance of social institutional arrangements “A tale of two widows”
And would the widower’s dynamic = the widow’s?
Mid-point summary
• We make no claim that this is THE definitive theory of resilience against chronic poverty. We merely claim that such theory(ies) is sorely needed to help shape the accelerating programming around resilience. This is one candidate.
• Such theory needs to explicitly link risk, poverty and supporting natural resources in an explicitly dynamic context.
• Theory becomes especially important as a bedrock for measurement for M&E and prioritization.
III. Measurement
General Measurement Principles – not specific to resilience but important across all measurement situations • • •
1. Gender-based analysis/gender equity and focus on women and mothers 2. Distinction between chronically poor and transiently poor 3. Measurement of non-market goods both subjective and objective elements 4. Measurement of observables and latent variables, leading to constructs/factors 5. Technical properties of measures –reliability and validity – and rigorous analysis of the origins and effects of measurement error

IV. Summary
Resilience is a popular buzzword now. But little precision in its use, either theoretically, methodologically or empirically. Aim to help facilitate rigorous, precise use of the concept to help identify how best to avoid and escape chronic poverty.
This will require advances in theory, measurement and empirical work in many different contexts and over time. We start by advancing a conceptual theory of resilience and measurement principles that derive from that theory. Much to do in all areas … a massive research agenda, especially as agencies begin using resilience as a programming principle.
