Title: International Migration
1International Migration
2International migration the basic numbers
- Between 1965 and 2000, the fraction of people
living outside their countries of birth increased
from 2.2 to 2.9 of world population - 175 million people in 2000
- Remittances have been huge and growing
Sources UN International Migration Report 2002,
US Census Bureau.
3Remittances vs. ODA, FDI(1991-2005)
- Source World Development Indicators 2007. Data
are in current US.
4Key questions
- How does emigration to the rich world affect the
economic outcomes of migrants themselves? - How does emigration to the rich world affect
families left behind, and origin-country
economies more broadly? - What policies might help raise the development
impact of remittances?
5Clemens and Pritchett (2008)
- A new statistic, income per natural the mean
annual income of persons born in a given country,
regardless of where that person now resides - Almost 43 million people live in a group of
countries whose income per natural collectively
is 50 higher than GDP per resident - For 1.1 billion people the difference exceeds 10
- Poverty estimates are very different for national
residents and naturals - 26 percent of Haitian naturals who are not poor
by the two-dollar-a-day standard live in the
United States - If economic development is defined as rising
human well being, then a residence-neutral
measure of well-being emphasizes that crossing
international borders is not an alternative to
economic development, it is economic
development.

8Causal effect of migration
- But what is the causal effect of migration?
- Observed income differences could reflect
- Labor-supply effect
- Selection effect
- Causal effect of migration
- Clemens and Pritchett (2008) review a variety of
studies finding that at least 75 of the income
difference is the causal effect of migration - Next examine one important study providing
estimated causal impact of migration on income - Gibson, McKenzie, and Stillman (2006)
9Gibson, McKenzie, and Stillman (2006)
- What is the impact of migration on the migrants?
- One of the most difficult problems in migration
studies, due to selectivity of migration - Very difficult to find an appropriate or
convincing control group - This paper use a lottery to obtain exogenous
variation in migration - Lottery for Tongans to migrate to New Zealand
- Estimate income gains from migration, using
lottery as exogenous variation - Compare estimates from lottery to OLS,
single-difference, double-difference, IV,
propensity score matching - Results IV with a good instrument performs
best - D-in-D and propensity score matching do OK as
well

15Yang (2008)
- What are impacts on families left behind?
- Specifically, what do remittances help pay for at
home? - Another natural experiment
- June 1997 6 of households in the Philippines
had one or more members working overseas, in
dozens of countries - July 1997 Asian financial crisis occurs
- Large, sudden, heterogeneous changes in exchange
rates in many locations of Filipino workers (see
figure) - Philippine peso also depreciates
- Examine impact of migrant exchange rate shocks on
Philippine households

Percent change in exchange rate
NOTESExchange rates are in Philippine pesos per
unit of foreign currency. Percent change in
exchange rate is mean exchange rate from Oct 1997
to Sep 1998 minus mean exchange rate from July
1996 to June 1997, divided by the latter. Mean
remittances are calculated among all households
with a single migrant in given overseas location.
Percent change in mean remittances is between Jan
- Jun 1997 and Apr-Sep 1998 reporting periods.
Datapoints are the top 20 locations of Philippine
overseas workers (as listed in Table 1).

Remittances and The Problem of Control A Field
Experiment Among Migrants from El Salvador
Nava Ashraf, Harvard Business School Diego
Aycinena, Francisco Marroquin University Claudia
Martinez, University of Chile Dean Yang,
University of Michigan
23DC-area Salvadorans on the problem of control
-
- I have many uncles and they get drunk, so I
just send money when needed, or I send to someone
like my sister who I trust. - Male, 34 years old, 8 months in the U.S., works
as roofer - The brother of my boss sent around 50,000 to
his mother over the years. When he thought he had
enough money to build a house, he asked his mom
for the money. She said she didn't have it. She
had lent it to an uncle. When he asked for the
money back, the uncle threatened to kill him if
he came back to El Salvador for the money. - Male, 30 years old, 1 year in the U.S., works as
a carpenter -
24Some open questions about remittances
- Do migrants and recipients typically agree on the
uses to which remittances should be put? - If not, how do such disagreements affect
- the choice of remittance recipients?
- amounts remitted?
- remittance uses?
- If migrants were to be given more control over
remittance uses - would they remit more?
- how would they direct them to be used?
- what would be the impact on household-level
development outcomes?
25Remittances and savings
- This research focuses on the control that
migrants have over how much of remittances are
saved - Migrants frequently report wanting household to
save some fraction of remittances - Savings potentially intended for use of either
recipient or migrant - Migrants report stronger preferences that
remittances be saved, compared to recipients - Migrants have little or no ability to control or
monitor household savings in El Salvador - Can only request that household save a portion of
cash received
26Why would migrants save in home country?
- If savings intended for regular use of family
back home, U.S.-based accounts are inconvenient - If savings intended for U.S.-based migrant, many
migrants consider U.S. savings insecure - Undocumented migrants fear they would lose
savings in the U.S. if they were deported - Currently an open question whether savings
accounts are primarily for recipients or
migrants use
27The experiment
- We offered Salvadoran migrants in Washington,
D.C. the ability to directly channel remittances
into savings accounts in El Salvador - Facilities developed for project in partnership
with Salvadoran bank, previously not widely
available - We randomly varied the degree of migrant control
over accounts offered - Outcomes of interest
- Demand for accounts (take-up)
- Savings accumulation
- Remittances (identity of recipients, amounts)
- Later household outcomes
- E.g., consumption, schooling, entrepreneurial
investment, housing
28Theoretical impacts
- How should remittances change if migrants had
more control over savings in the home country? - Case 1 funds saved out of remittances intended
for use of recipient household - If migrant and recipient have similar savings
preferences, increasing migrant control should
have little or no effect - If migrants prefer recipient to save more, then
increasing migrant control should lead to higher
remittances and savings - Case 2 funds saved out of remittances intended
for use of remitter (migrant) - Funds entrusted to remittance recipient, but
monitoring is imperfect a principal-agent
problem - Increasing migrant control over savings could
lead to higher savings (by migrant), but lower
remittance flows to family
29Treatments
- 0. Control group
- Migrants encouraged to remit into a household
members bank account, but no account-opening
assistance provided - 1. Account for remittance recipient in El
Salvador - Migrants encouraged to remit into an individuals
bank account - If no such account exists, offer to help
household set up account - Migrant cannot check balance or withdraw
- 2. Joint account (for migrant and household)
- Migrants encouraged to remit into shared account
- New product Cuenta Unidos
- Migrant and hh each have ATM cards migrant can
check balance - 3. Individual migrant account
- Migrants encouraged to remit into own account
- New product Ahorro Directo
- Only migrant has ATM card
- Not shared with household
30Marketing brochures
- Ahorro Directo Cuenta Unidos
31Rationales for treatment conditions
- 0. Control group Provides counterfactual for
assessing impact of offered savings facilities on
later household outcomes (savings, remittances,
consumption, investment, etc.) - Account for remittance recipient Provides
counterfactual of demand for accounts where
migrants have no control - If no differences vs. 2 and 3, indicates migrants
dont value control - 2. Joint account (for migrant and household)
Impact of having shared control over account - Monitoring of account balance
- Shared ownership
- But El Salvador joint owner has full ability to
withdraw - 3. Individual migrant account Impact of
exclusive control over account
32Hypotheses to be tested
- Hypothesis 1 Take-up of new savings products
will be - Highest for Treatment 3 (individual migrant
account) - Next-highest for Treatment 2 (joint account)
- Lowest for Treatment 1 (account for remittance
recipient) - Difference should reflect value migrants place on
control over savings - Hypothesis 2 Growth in migrant savings will be
- Highest for Treatment 3
- Next-highest for Treatment 2
- Next-highest for Treatment 1
- Smallest for Treatment 0
- In later rounds, will examine effects on other
household investment activities, such as
schooling, health spending, entrepreneurship
33Overview of treatment protocols
- Migrants recruited at Salvadoran consulates and
Banagricola remittance agencies - Must have remitted to someone in El Salvador in
last 12 months, and have been in U.S. for lt15
years - Subsample of migrants and recipient households
administered comprehensive baseline survey - Migrants randomly assigned to one of 4
experimental conditions - After stratification by gender, US account
status, years in US (3 categories), and
relationship to recipient (4 categories) - Marketing team member visits each migrant in
person to administer treatment - Visits take place in location of migrants choice
- Typically home, workplace, restaurant, nearest
Banagricola agency - Some visits arranged in advance, others occur on
the spot
34ESSMF marketing team
35Marketing visit (1)
36Marketing visit (2)
37Equalizing transaction costs
- Account-opening costs
- For all account types, account opening requires
visit by remittance recipient to a Banco Agricola
branch in El Salvador - Remittance transfer cost
- All accounts have equal cost of inbound
remittance - Inbound remittance costs also equalized with cash
remittance
38Remittance price randomization
- Remittance prices randomized between 4 and 9
- For a remittance up to 1500
- VIP card used to track remittances
- Will examine price elasticity of remittances
39Baseline survey contents
- Demographics, household composition
- Employment and income
- Detailed consumption in US and El Salvador
- Use of financial services
- Savings
- Remittances
- Credit
- Financial literacy, planning
- Communication and conflict with family
- Migration history
40Migrant survey Washington DC
41Household survey El Salvador
42Basic summary statistics
- Demographics
- 29 female
- Mean age 30.8
- Mean years in US 5.47
- Employment and income
- Top employment categories are construction (32),
food services (15), cleaning services (10) - For migrant, median annual earnings is 17,945
for surveyed individual and 25,458 for household - For recipient household, median annual income
2,864 - Remittances
- Most common remittance amount sent 200 (25)
- Median annual remittances 3,900
- Median remittances as share of migrant hh income
14.4
43Sources of income in recipient households
44Communication with family
- 86 of migrants have a cellphone
- 94 of migrants have not visited in the past 3
years (proxy for legal status) - 81 of migrants communicate at least once a week
45Methods of communicating with family
46Savings migrant
- 69 have a savings account
- 51 have one in US only
- 9 have one in El Salvador only
- 9 have one in both countries
- But savings are quite low for most migrants
- Median savings 700
- Median savings as of annual hh income 2.8
- Migrants express desire for more savings
- 37 very unsatisfied or unsatisfied with
current level of savings - 85 would open account in El Salvador if given
opportunity to do so
47Savings recipient household
- Only 21 have a savings account
- Savings are low
- Median savings 0 (mean savings 301)
48Revealing preferences for remittance uses
- Goal Reveal via survey answers whether migrants
and households differ in their preferences over
how remittances are used - Problem simply asking migrants and households
about their expenditure preferences may not yield
useful answers - Answers may be automatic, conditioned by what
respondents think is the right answer - Respondents may not think carefully (in way they
would if actual money were at stake) - Our approach enter respondents into a
remittance raffle - Winning family in El Salvador will receive
remittance of 100 - Migrants specify how they would like the money to
be used by recipients - Household respondent specifies how they would
like the money to be used when received - 13 categories of expenditures
- Cash is not an option
49Raffle use categories
- Daily consumption
- Clothing
- Housing (includes rent, construction, mortgage)
- Medical expenditures
- Educational expenses
- Utilities bills
- Phone bills
- Agricultural inputs
- Small business expenses
- Savings
- Durable goods
- Automobile payments
- Other (specify)
- Question Do migrants allocate more money to
certain expenditures than the corresponding
remittance-receiving households?

63Evidence for migrant control?
- Higher take-up in Treatment 2 and 3 vs. 1 may
indicate - Migrant desire for control, or
- Migrant desire for convenience (easy access to
funds from U.S.) - Take-up is not statistically significantly higher
in Treatment 3 vs. 2 - But 95 of migrants opening accounts in treatment
3 open Ahorro Directo (individual migrant
account) - Highly suggestive of migrant desire for control
- Data still to come will shed further light
assess whether total savings balances are
significantly higher in Treatment 3 vs. 2

67Summary of findings so far
- Migrant demand for savings accounts in El
Salvador rises when they are offered more
possibility of control over them - Demand is 60 higher when migrants have option of
joint or individual (migrant) ownership over
accounts, compared to accounts in the name of
someone else in El Salvador - Increase in take-up when migrants are
additionally offered option of individual
ownership (vs. joint ownership) is relatively
small - But when individual ownership is offered, 95 of
migrants opening accounts avail of individual
ownership - Highly suggestive of demand for migrant control
- Additional tests of importance of migrant control
await availability of savings data

70Principal-agent problem outline
- Remittances have two functions 1) funds for
investment by migrant (principal), and 2)
incentive payments for hh (agent) - Migrant sends funds for investment k, and hh
chooses fraction f that is spent in investment
(consuming remainder) - Household must conceal consumption of uninvested
funds at cost c(f) - Investment returns have random component, and
migrant cannot observe f, only total investment
returns x - Problem for migrant is how to reduce diversion of
funds by hh - Migrant implements incentive scheme for hh based
on returns x payments to hh are s(x) - Prediction ability to directly control
investments (e.g., savings, housing, education)
raises remittances-as-investment (k) but reduces
payments to hhs (s) - Total resources transferred by migrant should
rise, even as hh receives less
