on
the

Using
the
weekly
price
data
from
2007
to
2013,
this
paper
examines
whether
rice
markets
in
Madagascar
are
well
integrated
spatially.
It
finds
that
the
price
adjustment
of
Ambatorazaka
and
Anjozorobe
with
Antananarivo,
the
capital
city
of
the
country,
is
not
quick
even
though
they
are
located
near
to
Antananarivo.
Remoteness
does
not
explain
this
phenomenon
and
further
analysis
is
clearly
needed.

This
paper
reports
facts
about
arbitrage
of
rice
traders
in
Antananarivo,
Madagascar.
First,
even
in
the
same
period,
for
the
same
variety,
some
traders
are
purchasing
from
districts
with
higher
prices
when
some
others
are
purchasing
with
lower
price
in
different
district,
indicating
scope
for
better
arbitrage.
Second,
although
the
cheapest
district
changes
over
time,
most
of
the
traders
specialize
in
trading
in
few,
limited,
popular
districts,
which
are
not
always
the
cheapest
district.
Third,
consequently,
traders
often
fail
to
purchase
from
the
cheapest
district
and
therefore
are
paying
substantially
higher
prices
than
the
cheapest
price.
Fourth,
traders
do
not
search
price
in
other
districts
extensively,
and
their
knowledge
on
price
is
concentrated
in
very
few
districts.
Fifth,
our
randomized
controlled
trial
intervention
to
provide
regional
price
information
via
SMS
had
no
effect
on
purchasing
behavior,
arbitrage
efficiency,
or
quantity,
price,
and
margin
of
purchase.

How
Does
Contract
Design
Affect
the
Uptake
of
Microcredit
among
the
Ultrapoor?
Experimental
Evidence
from
River
Islands
of
Northern
Bangladesh
(400KB)

Despite
the
professed
claims
of
microcredit
for
poverty
alleviation,
little
is
known
about
what
kind
of
credit
contract
is
suitable
for
extremely
poor
households
or
the
ultrapoor.
To
fulfil
this
knowledge
gap,
we
initiated
a
field
experiment
in
river
islands
of
northern
Bangladesh,
where
a
substantial
portion
of
dwellers
belong
to
the
ultrapoor
due
to
cyclic
floods.
We
randomly
offered
four
types
of
loans
to
such
dwellers:
regular
small
loans
in
cash
with
one-year
maturity,
large
cash
loans
with
three-year
maturity
with
and
without
a
one
year
grace
period,
and
in-kind
livestock
loans
with
three-year
maturity
with
a
one
year
grace
period.
We
compared
their
uptake
rates
as
well
as
the
determinants
of
uptake
and
found
that
the
uptake
rate
is
lowest
in
the
regular
contract,
followed
by
the
in-kind
contract.
Contrary
to
prior
belief,
we
also
found
that
the
microcredit
demand
of
the
ultrapoor
is
not
necessarily
small
and
in
particular
the
ultrapoor
are
significantly
more
likely
to
join
the
program
if
a
grace
period
with
longer
maturity
is
attached
with
a
relatively
large
amount
of
credit,
irrespective
of
whether
the
credit
is
provided
in
cash
or
kind.
This
paper
provides
evidence
that
a
typical
microcredit
with
one-year
maturity
without
a
grace
period
is
not
attractive
for
the
ultrapoor.
Microfinance
institutions
may
need
to
think
of
longer
maturity
loans
with
convenient
grace
periods,
without
compromising
the
loan
repayment
schedules,
to
fulfill
the
need
of
the
ultrapoor.
