1. Abstract
Improved rural roads are increasingly showing potential for creating opportunities for
economic growth and poverty reduction in developing countries. Reduced transport costs
can lead to increased productivity and demand of labor for men and women in farm and
non-farm activities as well as larger investments in health and education for rural
households in most remote areas. In that sense, this intervention has the potential to
effectively reach a sector of the population that has been persistently marginalized from the
benefits of aggregate economic growth in Peru. Still, methodological constraints and data
limitations have made it difficult to measure the size of these benefits with precision. This
proposal attempts to contribute by evaluating a rural roads program in Peru using a quasi-
experimental approach that allows controlling for time-invariant unobserved characteristics
of villages and households. We propose to use a unique longitudinal dataset that enable us
to measure impacts on a wide variety of socio-economic, institutional and environmental
characteristics. We also plan to explore heterogeneity in the impacts by individual,
household and village characteristics, as well as conditioning factors for the realization of
benefits. Thirdly, knowing the time at which road maintenance started enables us to explore
about the time lags required for the benefits to show up. Thus, this study will not only be
able to tell the program whether they are having positive impacts but also help find ways to
improve their contribution to poverty alleviation by informing about the conditions that are
required for those positive effects to materialize for the neediest.

2. Main Research Questions and Objectives
The Rural Roads Rehabilitation and Maintenance Program is run by the Ministry of
Transport and Communications (MTC) aims at improving transport conditions in rural
villages by supporting local governments and small and medium local enterprises to
manage and carry out, on a sustainable basis, the maintenance and upgrading of rural roads
in the poorest areas of Peru. Such sustainable interventions will integrate poorly accessible
zones to regional economic centers, reducing transport costs and raising the reliability of
vehicular access to expand markets for agricultural and non-farm products and enhancing a
more diversified set of employment opportunities for rural households. Improved
transportation will also reduce time to reach basic social services such as health, education
and justice1.
Additionally, economic review supports that there is a positive effect of the program
on rural households’ income (Ahmed y Hossain; 1990). However, the way in which this
income increase is assigned at households relates to higher value of real estates (Jacoby,
2000) and new opportunities in non farm activities2, more than an increase in the
productivity of the agricultural sector.
The effect on the productivity and agricultural income depends on the specific
circumstance and also on the possibility of complementarily interventions: like technical
support, credit access, among others (Biswanger, Khandker y Rosenzweig, 1993).
1 For example Levy (2004) provides evidence that girls’ school attendance is highly increased with an improved in transport conditions. For a review of several impact studies on access to health services see Porter (2002), Hettige (2006), Windle and Cramb (1996).

The program includes the rehabilitation and maintenance of rural roads, connecting
primary and secondary roads; and non-motorized rural transport tracks. In the process; the
program also tries to promote institutional development by providing technical assistance to
local governments and small and medium local enterprises for improved planning and
management of rural roads and for the development of micro-enterprises formed by groups
of beneficiaries for road maintenance.
This proposal attempts to address at least the following research questions:
1) Does the Rural Roads Program (RRP) have a positive effect on rural households´
income, health, education, etc? Another important expected effect is the diversification
of income opportunities in terms of the reduction of the dependence on agriculture and
the increase of wage employment and non-farm independent economic activities.
2) Do some special groups benefit more from the rural roads program? In particular, to
what extent do poorest households, smaller communities, rural women, and other
especially marginalized groups, benefit from the enhanced economic environment
resulting from the RRP?
3) How long does it take for the impacts of the RRP to show up? Does the answer vary by
indicator?
4) Does the presence of other public programs or access to other infrastructure and
services make it more likely for the effects of the RRP to be positive and significant?
2 See for instance Hine y Riverson (2001), Jacoby (2000) and Escobal y Ponce (2002).

5) Does the RRP have unintended negative effects such as accentuated land degradation,
child labor, crime and violence?
3. Scientific Contribution
The economic literature has been increasingly reporting mechanisms through which
improved roads can create opportunities for economic growth and poverty reduction
(Khandker, 2006). By reducing transportation costs, improved roads can increase
productivity and demand for labor in farm and non-farm activities thus leading to increase
income and consumption as well as household investments in health and education.
However, methodological constraints and data limitations have made it difficult to
measure the size of these benefits. Most of the previous studies have lacked panel
observations and appropriate control groups to correct for unobserved heterogeneity. Only
recent studies have started to use double-difference techniques (Khandker et. al., 2006; van
de Walle and Cratty, 2005). However, they have not been able to fully address the
heterogeneity of impacts across individuals, households and villages.
Another feature of this literature is that it seems to concentrate on experiences in
Asian countries. A noted exception is Escobal and Ponce (2002) who evaluated the
Peruvian Rural Roads Program by using a propensity score matching methodology with a
cross-section survey. Their results suggest that improved rural roads enhance income
opportunities for rural households, especially non-farm wage employment. However, these
income gains seem to be perceived as only temporary since household decide not to
increase consumption but rather increase savings through increments in livestock.

This paper attempts to contribute to the related literature by evaluating a rural roads
program in Peru, using a quasi-experimental approach that allows controlling for time-
invariant unobserved characteristics. Access to three rounds of a specialized survey allows
constructing a unique dataset that enable us to measure impacts on a wide variety of socio-
economic, institutional and environmental characteristics. We are also able to explore
heterogeneity in the impacts by individual, household and village characteristics, as well as
conditioning factors for the realization of benefits. Finally, knowing the time at which road
maintenance started enables us to explore about the time lags required for the benefits to
show up.
4. Policy Relevance
The Rural Roads Program is a large program that has been operating in Peru since 1995.
The first phase of the RRP was carried out during 1995-2000 in 12 departments that ranked
highest in rural poverty. During that first phase, the project improved rural accessibility in
314 districts by rehabilitating about 11,200 kilometers of rural roads and key secondary
roads and about 3,000 km of paths for non-motorized transport3. A key important feature of
this program is that it has included a valuable impact evaluation component that, for
example, has funded the three rounds of data collection that are going to be used in this
study. In that sense, it is very important that such effort is rewarded with an impact
evaluation study that not only tells them if the program is having positive impacts but also

helps them find ways to improve their contribution to poverty alleviation by informing
about the conditions that are required for those positive effects to materialize.
With still very few public programs having adequate evaluation components in
developing countries, it is important to publicize their usefulness not only for the continuity
of the program but also for the identification of the need to adjust some of its components
to increase the magnitude of the positive effect, or to make this effects reach the poorest,
excluded and most vulnerable. This is particularly useful in Peru as a new government has
just assumed and they are in need of knowing which programs to expand and which ones
they may explore to close.
5. Methodology
The study will use the double difference estimate to determine the impact of the rural roads
program on a wide variety of indicators at the level of the household and the localities
involved. The project will make use of three rounds of a specialized household and
community-level survey that includes a wide variety of socio-economic, institutional and
environmental indicators. For each round, a set of rural roads and non-motorized tracks to
be treated were randomly selected to be included in the evaluation study. For this randomly
selected treatment group, a control group was selected ex-ante. The control group was
selected so that they are similar to the treatment group in terms of observable variables such
as the longitude and type of road (rural road or non-motorized track), characteristics of the
8
villages involved such as population size, access to basic public services and
infrastructure4.
A basic regression-based DD estimate can be obtained from the following regression:
ijtTCj
ADt
TCj
ADtijt DDDDY εβββ +⋅⋅+⋅+⋅= 321 (1)
where ijtY denotes the value of an indicator of interest for household i that resides in village
j at period t (t=0 is the baseline; t=1 is the follow-up survey). TCD is a categorical variable
that takes value one if the household resides in a treated village and zero if it resides in a
control village. ADD is a categorical variable that takes value one if the observation is from
the follow-up survey and zero if it comes from the baseline. In that setting, 3β is the DD
estimator of the impact of the program on variable Y 5. It is often referred as an average
effect because it refers to all beneficiaries without distinction.
If we identify systematic differences between the treatment and control groups in
observable variables, we would need to include some controls in expression (1) to check
the robustness of our DD estimate. Furthermore, we cannot assure that there are non-
observables that can establish systematic differences between treatment and control groups,
but the double-difference (DD) estimate can help control for any time-invariant systematic
non-observable difference by including village fixed effects. Thus, a full version of the
average DD estimate can be obtained from the following expression:
4 In addition, control roads were also required not to have any intersection with a treated road or track. 5 In case of dichotomic variables, the estimation of the marginal effects is somewhat more complicated. See Karlan and Valdivia (2006).

ADtjijt DDDDXY ευβββα ++⋅⋅+⋅+⋅+⋅= 321 (2)
where X is another dichotomic variable that takes value 1 if the village has the
characteristic of interest or concern. jυ denotes the vector of community fixed effects.
Finally, ijε denotes the error term which is assumed to be independent across villages but
not necessarily within them6.
We expect heterogeneous effects depending on the characteristics of the roads and the
beneficiary villages. The associated econometric analysis will use the following
formulation:

In that case, 3β comes to be the DD estimator of the program´s impact for those
households that reside in a village that does not have the characteristic of interest X, and
33 γβ + is the one for those that do have it.
6. Data Requirements and Sources
This proposal pretends to use three rounds (2000, 2004 and 2006) of a specialized
household and community-level survey that includes a wide variety of socio-economic,
6 Thus, we use the Huber-White covariance matrix estimator to obtain the standard error of our coefficients of interest.
10
institutional and environmental indicators7. The survey questionnaires were the same for
the three rounds, and they all were applied in the fourth quarter of the corresponding years,
so that consistent comparisons are allowed. The household survey includes information
about the characteristics of the dwelling, health and education of all household members,
farm and non-farm entrepreneurial activities, commercialization channels, etc8. The
community-level survey is applied to key local informants and includes information about
the characteristics of the villages in terms of access to public infrastructure and basic
services, distance to nearest markets, and other key public facilities. It also includes
characteristics of the roads such as the time required to travel from the initial to the final
point of the road by the different means, number of public transportation units that use the
roads, the number of months the road remain closed over the past year, number of car
accidents, maintenance and operation costs for public transportation units offering services
in the road. Also, number of students in primary and secondary schools, number of health
services offered by public health facilities, judiciary and police crime records, use of
associated roads, among many other variables.
For each round, a sample of rural roads and non-motorized tracks to be treated were
randomly selected to be included in the evaluation study9. For this randomly selected
treatment group, a control group was selected ex-ante. The control group was selected so
that they are similar to the treatment group in terms of observable variables such as the
7 The first two rounds of the survey were applied by the firm Cuánto that won the corresponding call made by the Rural Roads Program for the evaluation of the program. The third round is currently being applied by GRADE as they won the last call. 8 See Table 1 and Table 2 below for a list of the main indicators available in all survey rounds.

longitude and type of road (rural road or non-motorized track), characteristics of the
villages involved such as population size, access to basic public services and infrastructure,
altitude. In addition, control roads were also required not to have any intersection with a
treated road or track to minimize the probability that benefits on treated villages spill over
the control villages. Table 3 shows the pre-treatment means for treatment and control
groups for many observable variables, showing there are almost not statistically significant
differences between these two groups.
Treated and control roads are associated to villages by defining the origin and the end
of the road. In the case of small roads or tracks (less than 20 kms.), 6 households were
randomly selected within the initial and end villages. In the case of large roads, an extra
intermediate village is included in the sample. In the 2000 round, a baseline was established
with 2,000 households residing in villages associated to a sample of the roads that were
going to be treated during the 2001-02 period. In the 2004 round, the survey was applied to
the panel of households from the first round, plus 2,457 households associated to the
villages associated to the villages that were going to intervene during the period 2004-05.
Finally, in the 2006 round, we are following the households from the two previous rounds
plus 1,743 new households associated to the program´s intervention plan for 2007.
7. Dissemination Strategy
The hope of those involved with this study is that its results will help identify and
implement some adjustments to the program that can help their benefits to reach the

poorest. To achieve this goal, the results of the study must be made available and
distributed to a wide and diverse audience of local academics, policy-makers, and
development practitioners. To target as many audiences as possible, the research team will
produce a technical working paper as well as a less technical presentation of findings upon
completion of the data analysis stage.
Upon completion of the study, a technical paper detailing the double-difference
estimates of the impact of the RRP on the various variables considered as key indicators for
the program, including socio-economic conditions as well as institutional and
environmental variables. This paper will be first published as a working paper in GRADE.
Availability on the web will allow researchers over the world to reach the information. This
version will be developed into a paper that would be submitted for publication in a peer-
reviewed journal, and the policy recommendations would be extended beyond the local
environment to the worldwide development community.
Moreover, GRADE’s institutional visibility will greatly increase the circulation of the
results within Peru. As one of the most widely-respected development think-tank in the
country, GRADE has links to numerous government ministries and a number of local
NGOs. Therefore, a dissemination paper focusing on policy recommendations will be
drafted and then published in GRADE’s bulletin Análisis y Propuestas, which is widely
distributed among local politicians, policy makers and development practitioners.
Finally, we expect to take advantage of the accumulation of impact evaluation
projects PEP has funded with GRADE researchers. In case we get the funding for this
proposal, we will have three projects that evaluate the impact of anti-poverty programs
13
using different methodological approaches. The first project was directed by Martín
Valdivia on “Business Development Services for Female Microfinance Clients in Peru: A
Randomized Impact Evaluation”. The second project is being directed by Miguel Jaramillo
on “Do the Poorest among the Poor Benefit Less from Active Labor Market Programs?
Evidence from PROJOVEN”. In that sense, we propose to use that accumulation of
knowledge on impact evaluation studies within GRADE to raise awareness among local
policy makers and the local research community about the need of rigorous evaluations of
anti-poverty programs to learn systematically about what really works for the poor. Thus,
besides the regular dissemination article in Análisis y Propuestas for each project, we
propose to generate one that focuses on the lessons learnt from the three projects from a
methodological and conceptual standpoint, trying to make a case for the local public and
private sector to raise the standards on the evaluation of anti-poverty programs. That article
will be followed by a special conference in which we will try to make the case, maybe with
the help of other experienced researchers with international recognition in the area,
including those from PEP.
8. Ethical, Social, Gender, or Environmental Issues or Risks
The design of the project used the opinions of potential beneficiaries expressed through
focus groups organized in several rural communities (see Ford and Menendez, 2005). The
World Bank and IADB made sure to organize separate focus groups for men and women so
that women were able to express their opinions independently. This explicit inclusion of
women generated a key adjustment in the design of the program, to include funding for the
rehabilitations and maintenance of non-motorized transport tracks, which are the ones
14
women used most often ignored by road upgrading programs. Focus groups after the
intervention have also received special attention and they suggest that a large proportion of
women see the program benefit them in terms of enabling them to travel farther and more
safely, and has also enable them to increase their income. The impact evaluation proposed
here will pay special attention to the effect of the program on women´s employment,
education and health, to see whether the program benefits them more or less than it does to
men.
Improving the connection of rural communities to markets has some environmental
risks as households may respond to the increase in profitability by increasing the intensity
in the utilization of scarce natural resources such as land, eroding the soils and affecting
their future productivity. The study will also monitor the intensity in the use of land in
agricultural activities.

11. Research Capacity Development & Division of Labor
This project will be developed by three young female researchers under the advice of a
male senior researcher, Martín Valdivia. Paola Vargas will serve as the coordinator of the
project. Martín Valdivia will serve in an advisory role throughout all phases of the project.
However, his direct input will be counted on more heavily in the latter stages.
The three young female researchers have recently graduated as economists and have
been working as research assistants in GRADE. So, this experience will be the first one in
which they will be in charge of a research project. Paola Vargas has already had some
exposure in impact evaluation studies, but for Vanessa Cheng and Valerie Koechlin this
project will significantly enhance their knowledge of the different methodological
approaches associated to impact evaluation of poverty alleviation programs.
The division of labor between all project members will be as follows:
1. Identification of Control groups (Vanessa Cheng - VCh)
2. Monitoring and Administration of the second follow-up survey (VCh & Valerie
Koechlin - VK)
3. Processing of three rounds of survey database (VCh, VK & Paola Vargas – PV)
4. Analysis of all Databases (VCh, VK, PV)
5. Analysis and Discussion of Results. (PV & & Martín Valdivia - MV)
22
6. Evaluation of Policy Recommendations. (VCh, VK, PV & MV)
7. Preparation of Final Document. (VCh, VK, PV & MV)
