Outline • Motivation • Elements of the aspirations framework • Aspirations project • Field experiment – design and findings
Motivation – why aspirations • Conceptual – ‘opportunities’ • Empirical – Why do the poor not ‘invest’? • Ethiopians and fatalism? • Focus 1 - ‘external circumstances’ and ‘opportunities’. • Low returns to investments; • Unexploited opportunities due to lack of information or knowledge; • Social constraints; • Focus 2 - constraints associated with the manifested attributesof decision makers • Identity issues: sense of self; • Psychological issues: impatience, commitment, and psychological barriers • Aspirations failure perspective
Aspirations: A desire or an ambition to achieve something An aim and implied effort to reach it A set of future-regarding preferences Related concepts Economics : Satisficing Psychology : Self-efficacy, locus of control Anthropology : Aspiration failures Common elements Goals and aspirations are important determinants of success; Evolution through time in response to circumstances; Role of social comparisons and learning from relevant others, An individual-level yet culturally (collectively) determined attribute towards exploration of individual-group symbiosis Elements of the Aspirations Perspective
What are Aspirations? Aspirations have two distinctive aspects: Future-oriented - are goals that can only be satisfied at some future time (differ from immediate gratifications); Motivators - are goals individuals are willing, in principle, to invest time, effort or money in to attain (different from idle daydreams and wishes) Note: the ‘willingness to invest’ is ‘potential’, or ‘conditional’ Aspirations and expectations – preference vs. beliefs; Elements of the Aspirations Perspective
Elements of the Aspirations Perspective Why are aspirations important/useful? Aspirations (or the capacity to aspire): • Reflect bounded rationality; • Are socially determined (social interaction); • Are distributed unevenly within communities. • Condition individual behaviour and well-being • Useful device in analysing and/or addressing poverty
Elements of the Aspirations Perspective How do aspirations condition individual behaviour? • Aspiration window: • an individual’s cognitive world, his/her zone of ‘similar’, ‘attainable’ individuals; • Reflects the information and economic opportunities of the local environment; • Multi-dimensional (‘similarity’); • Aspiration gap: • difference between the aspired ‘state’ and current ‘state’ • Conditions future-oriented behaviour - inverted U relationship between gap and effort A possible outcome is anaspiration failure - lack of pro-active behaviour (or ‘under-investment’) towards filling the aspiration gap
Elements of the Aspirations Perspective Measurement Issues • Aspirations are not directly observable • Revealed by observed behaviour: interpretation issues (linking aspirations and behaviour) • Elicited using subjective questions: measurement issues • Limits to subjective assessment: • Subjects: subjects’ willingness to report private knowledge, evaluation apprehension, and subject role playing • Instruments (attributes of): order of questions (anchoring), the number of categories on the rating scale (odd-even), the adjectives that are used as the endpoints of the rating scale, and the adverbs that describe scale categories. (e.g. Delavande et al. (2009), Bertrand and Mullainathan (2001) for reviews)
Elements of the Aspirations Perspective Identification issues • individual characteristicsaffect aspirations, aspiration windows and behaviour (e.g. schooling levels, wealth, and family background), Particularly the endogeneity of the aspiration window a key hurdle • aspirations ‘cause’ success – a person with higher aspirations may be more successful. • Success ‘causes’ aspirations – a successful person may revise his/her aspiration to a higher level, or experiment, panel data
The “Aspirations” project Step 1 – correlates of aspiration-related concepts Step 2 – test and validate a measurement strategy Step 3 – assess validity of the “aspiration window” hypothesis • An experiment • Exogenous shock to aspirations: Mini-documentaries of local success stories screened to randomly selected individuals. Placebo: local TV show. • 3 rounds of data • Baseline pre-treatment (Sept-Dec 2010) • Aspirations retest immediately after treatment • Follow-up (Mar-May 2011)
Field Experiment - Aspirations Measures 200,000 ETB ~ value of one harvest of chat from one hectare 100,000 ETB ~ value of one harvest of chat from half a hectare 0 ETB
Field Experiment – Design • 16 Screening sites, 4 villages/screening site (2 Treatment, 2 Control), • 36 households/village (18 households surveyed, 18 households not surveyed) Treatment village Placebo village Surveyed : Treatment, 6 households (12 individuals)/village Placebo, 6 households (12 individuals)/village Control, 6 households (12 individuals)/village Non-Surveyed : Treatment, 18 households (36 individuals)/ treatment village Placebo, 18 households (36 individuals)/ placebo village

Observations • "Weak" treatment, but: • Documentaries affected aspirations, expectations, savings behaviour, and perceptions more than the placebo even 6 months after treatment; • Direct and, even more visible, indirect (group) effects are detected – more of an aspiration window story rather than a role model one; • Further analysis; • Expanding coverage – Malawi, Pakistan via IFPRI;
