Slide2ObjectiveThis project aims at studying the role of subjective expectations about employment and earnings
in
influencing
occupational and migration choices
of university students in Mozambique
.
By
collecting detailed survey data from students at UEM we aim at shedding
light
on the underlying causes of important socio-economic issues such as
high university drop out, youth unemployment and skilled
migration
(brain drain)
in Mozambique
.
Slide3Background -1People take forward-looking decisions
depending on
expectations on their own returns (
Kimbal
, 1990)
Subjective expectations
are heterogeneous (we are agnostic on how they
are formed)
and people react to them making up their own mind over intertemporal choices
In
contexts
of
incomplete markets and high
risk, uncertainty
on
ex-ante
economic returns (as opposed to
ex-post
ones) may play a significant role in shifting
key lifetime decisions - such as education, occupation, migration
(
e.g.
Manski
, 2004; Jensen 2010;
Attanasio
2009;
Delavande
et al. 2011).
Human capital investment decisions have been shown to have a long-lasting impact on
wage inequality, economic growth, and employment
, leading to interest in the subject from policy makers as well as researchers
Slide4Background -2Not only expectations are important for people’s sorting in specific economic outcomes (e.g. occupation), but
perceived
expected returns can easily become
self-fulfilling
(Reuben,
Wiswall
and Zafar, 2015)- For
example
Youngsters
with low-expectations will have a smaller incentive to perform well academically, or subsequently they will be willing to accept a low-paying job offer and less likely to negotiate for higher salary because it is in line with their
beliefs
Students with
high expected
probability of working in the agricultural sector may believe such occupation is low-skilled and low-paid, therefore they will drop out from school and end up having a low wage.
Slide5Policy relevance..In developing contexts, getting hard evidence on individual expected returns on key human capital investments may have important implications in terms of both education and
labour
market
policy.
Using choice data, while assuming
homogenous
earnings
’
expectations,
is problematic since observed choices might be consistent with several combinations of expectations and preferences- especially in contests of high heterogeneity and
uncertainty.
Getting
to know people’s expectations and how they act upon them may provide,
ceteris paribus,
direct evidence on the relevance and severity of imperfections (e.g. in the information or insurance market) in determining actual investment behavior.
Slide6..and questions:Are Mozambican youngsters informed about the actual labor market opportunities?Do young people have correct expectations (information) about returns to schooling (and dropping-out)?To what extent expected income uncertainty affect youngsters’ education and occupational choices?
To what extent over- or under-estimated expectations play a role in the skill-mismatch in the labor market?
And on migration choices?
Slide7MozambiqueMozambique has been growing steadily over the last decade (7%), mainly due to an extractive resource boom.
Yet, job creation has been slow and unemployment rates hardly declined over the same period, especially among youth.
On the supply side, more than 300,000 people enter the labor mkt every year and this is poised to increase at about 500,000 by 2025 (WB 2015)
Rates of return to higher education has been increasing from 6% in 2002 to 18% in 2008.
A higher education degree increases wages by 148% compared to those with secondary
education
(WB 2015)
Slide8Employment rates by gender and educational attainment (INCAF 2012)
Slide9Employment rates by occupation / income source (INCAF 2012)
Slide10Slide11MozambiqueExpanding the share of skilled workforce is a crucial
condition for
long term and sustainable
growth.
The country has already
prioritized the development of higher education with a focus on science and
technology (PARP, CPS-WB 2014, WB-HEST, Let’s Work etc.).
The
number of higher education institutions have increased from 3 to 48
btw 1992 and 2014, also thanks to strong links with private sector.
This
is intended to address a problem of skills mismatch, to respond to a fast demand of highly specialized skills and to improve productivity
both in the formal and
informal
sector
(WB 2014
).
Slide12MozambiqueYet,
so far the
demand for tertiary educated workers has
been still
growing more rapidly than supply in Mozambique.
Completion
rates at higher education institutions are still low
:
only about one out of three of those who enroll into university do actually
graduate (UEM 2012).
Moreover,
among those who graduate many decide to emigrate
abroad (45%).
This translate in companies
often
importing
skilled
labour
from abroad (e.g. from
neighboring
countries
and even overseas).
Slide13Data collectionWe plan to collected information on a random sample of (about 800) students from different years and majors (Arts&Social
Sciences, Science, Engineering, Medicine, Architecture, Law, Economics, Mathematics, Informatics)
in UEM through a unique survey
We collect information on students’ current or intended major (if junior)
For each major, we
elicit from the students their
expectations about their likelihood of choosing future careers (including migration) and how much they
expect
to earn in them
, where the period of reference may be
10
years after they graduate (to recover the present value of lifetime earnings
).
Slide14More specifically, we ask students what are their expectations with respect to possible future outcomes
in each occupation under
different scenarios (i.e. university degree, drop-out)
the focus will be
both on
expected
average
income and
on income
variance.
To measure the variance of income, the survey will elicit
the
probability density function of
students’
expected earnings. It does this using five “bins” of different income levels and asks the students to allocate 100 “points” across the bins to reflect what they believe is the probability they would receive that level of income, conditional on successfully pursuing that occupation.
We also ask students what is the probability they will end up in certain
occupations
(and in the migration status).
We shall use broad
groups
to characterize possible careers: e.g. Science/Technology, Health, Business, Government/Non-Profit, Education and Law (Arcidiacono et al.
2014)
Alternatively, we may characterize occupations as wage work,
entrepreneurship and
inactivity (Osman 2014).
Slide15Importantly, for all students in the sample, those probabilities and expected earnings are elicited for all possible occupation-major combinations, i.e. both for the chosen (or intended) majors and the counterfactual majors
.
This will allow us to examine the possible complementarities btw majors and expectations, both in terms of earnings and preferences (i.e. how attractive working in a particular occupation is with different majors). For example, expected returns for business carriers are highest for economics major, which in turn leads people to report higher
prob
of pursuing a business occupation in the (sometimes)
hypothetical
case that they were an economics major
We further collect
a
wide range of background characteristics (including financial aid/constraints) of students as well as measures of risk aversion.
Slide16Analysis -1By using subjective expectations data on occupations for all counterfactual majors, we are able to
isolate
the separate influence of monetary returns from non-pecuniary factors
quantify
the importance of sorting across occupation on ex-ante
monetary returns,
keeping all the rest constant.
Identification: using
stated choice is advantageous because we rely on expectations elicited at the time of the choice in a hypothetical scenario that we seek to explain; this is equivalent to a situation in which
respondents’
preferences are elicited
before
they make their educational or career decision. S
uch ‘timing’
mitigates the
endogeneity issue.
Slide17Analysis -2Hence, this kind of data allows us to do
3 things:
identify
the
ex-ante
impact (treatment effect) of particular occupations (relative to a reference
one)
on earnings, for any given college
major (and for both graduating and dropping-out)
identify
the
ex-ante
impact of migration on earnings, for any given college
major
identify
the
ex-ante
impact of particular majors on the probability of working in any given occupation and on migration
the
differential
effect of a treatment on a 'treatment group' versus a 'control group' in a natural experimen
Slide18Intended Q&A- 1Do youngsters have well-informed or ‘correct
’ expectations about future earnings?
We shall compare
elicited expectations (in particular
wrt
earnings) with actual data from IOF
2014-15
(most recent data containing some labor market information)
From this set of information we see where UEM students believe they rank relative the population (if
possible, by
comparing earnings by major-occupation combinations or at least by educational attainment)
Slide19Intended Q&A- 2To what extent expected economic returns (pecuniary and non-pecuniary) affect people behavior with respect to human capital investment decisions?
We do so by looking at the difference between the
ex-ante
treatment effect of occupation
k
on the treated (i.e. by weighting the difference in the reported earnings by the probability
p
i
the individual reports she will work in occupation
k
) and the
ex-ante
treatment effect on the untreated (i.e. by using the weighting
(
1
-
p
i
))
The latter
gives a measure of the importance of
selection
on the expected returns to each occupation (a positive difference is consistent with positive
sorting
on expected earnings in different occupations- the magnitude of the difference is also important though)
Intended Q&A- 3What is the role played by expected earnings in the choice of students’ occupation?What is the role played by expected earnings in the choice of students’ migration?
We can look at this by estimating the probabilities of choosing particular occupations as a function of the (log) expected earnings controlling for individual-occupation preferences (dummies) and major-occupation fixed effects.
This may be derived by as simple model of occupation choice, which provides a link between subjective expectations and preferences, making it possible to tell apart the role of expected earnings and non-pecuniary factors in this context.
Slide21Alternative follow-up interventionsStudents are re-interviewed after they graduate, allowing for the measurement of how their actions in the
labor market line up with their
reports in the first round of the survey
Students are followed over time in order to collect their actual occupational choices and realizations
(Part of the) students are provided with information about the distribution of incomes in the different occupations (either domestically or abroad). Students are asked again
to provide their expectations of outcomes in the different occupations and
the corresponding
updates
to their
occupational/migration
intentions. This allows for the measurement of how the
expectations and
intentions
are
impacted
by an information
intervention.
