ABSTRACT
We show that armed conflict affects social capital as measured by trust and associational membership.
Using the case of Uganda and two rounds of nationally representative individual-level data bracketing
a large number of battle events, we find that self-reported generalized trust and associational
membership decreased during the conflict in districts in which battle events took place. Exploiting the
different timing of two distinct waves of violence, we provide suggestive evidence for a rapid
recovery of social capital. Evidence from a variety of identification strategies, including difference-in-
difference and instrumental variable estimates, suggests that these relationships are causal.

INTRODUCTION
This paper aims to increase the understanding of the legacy of civil war by analyzing the impact of the
Ugandan armed conflict on social capital. What is the impact of civil war on social networks? How does
violence affect trust? Providing an answer to these questions is important for conflict researchers for a
number of reasons.
First, it is argued that differences among societies in culture² the prevailing values, attitudes, and beliefs²
contribute to differences in economic outcomes. Social capital, which is a broad characterization of culture,
is one of the aspects considered. In the seminal work by Putnam (1993), social capital is defined as the
features of social life, networks, norms and trust that enable participants to act together more effectively to
pursue shared objectives. Social capital arises when people interact in a number of settings, ranging from
membership in an organization to attendance at religious services and to dinner with a group of friends. Since
a person is less likely to cheat someone who is a member of his social network, social capital makes people
more trustworthy (Coleman 1988). And, vice versa, trust is a prerequisite for building social networks. For
these reasons, trust is often associated with the value of social networks (Fukuyama 2000).
Following Putnam (1993), several scholars have focused on the role of social capital in shaping economic
performance (Colletta and Cullen 2000, Sobel 2002, Woolcock and Narayan 2000). For instance, Colletta
and Cullen (2000) argue that high levels of trust in a society reduce transaction costs and private protection
costs, thereby providing stronger incentives for investment and innovation. Early cross-country studies
confirmed the positive association between social capital, trust and indicators of economic performance
(Knack and Keefer 1995, 1997, Zak and Knack 2001, Guiso et al. 2004). And, in the new growth literature,
these aspects of culture are considered to be fundamental drivers of economic growth, having the potential to
lift the economy to a higher level growth path (Weil 2009).
Second, social capital may be particularly relevant for the economic development of countries with weak
formal institutions, which host most of the present-day civil wars (Blattman and Miguel 2010). In these
countries, the vacuum left by the absence of formal institutions may be filled in part by informal institutions
that overcome coordination failure. For example, a well-networked society may provide a solid base for
mutual aid and informal insurance and facilitate the flow of information and collective action (because
people who already have a relationship with each other can trust one another to do their part in a joint
enterprise). Furthermore, social capital may stimulate the accountability of ill-functioning governments.
People who care about their fellow community members may be more likely to vote. Thus, politicians in an
2
environment where social capital is high may be less inclined to abuse their constituents for personal gain.
This functioning of social capital may be welfare enhancing, as is suggested by the findings of several
empirical studies in developing countries that report a positive impact of social capital on household
expenditure, access to credit, public-service provision, and the adoption of new technologies in agriculture
(Grootaert et al. 2002, Isham 2002, Narayan and Pritchett 1999).
Third, although culture is generally perceived as sticky and able to change only slowly, there is a strong prior
that exposure to violence can affect certain aspects of social capital. A recent study by Nunn and
Wantchekon (2011) provides some support for this prior as it establishes a link between 400 years of slave
trade and the development of a culture of mistrust in Africa that persists to this day. Scholars have also
highlighted the role of interstate wars, e.g. World War II, in shaping national identity and state-building by
reinforcing social cohesiveness and collective action both within and across states (Hanson 2003). However,
civil wars, which are fought between opposing factions in a society, are often thought to be disruptive of the

Wantchekon. All errors and opinions expressed remain our own.

However, if social capital is formed at the subgroup level, for example, according to ethnic or regional origin, then it
may serve as an instrument of exclusion and polarization rather than an instrument of social gain and cohesion
(Fafchamps, 2006).

society's social fabric thus endangering its political stability and economic recovery (Colletta and Cullen
2000, Collier et al. 2003).
This rather pessimistic view has been challenged by recent micro-level studies. Studying the aftermath of the
1991-2002 civil war in Sierra Leone, Bellows and Miguel (2006, 2009) have shown that victimization during
the conflict increased political participation. In particular, households directly experiencing displacement or
more intense violence were more likely to attend community meetings, join political and community groups,
and vote. Similar findings have been presented by Blattman (2009) who investigated the impact of rebel
conscription by abduction on post-war social and political participation in Uganda. His analysis suggests that
the level of violence witnessed during the war as an abductee leads to more participation in political life but
does not affect membership in non-political organizations. In a related paper, investigating the impact of
conflict on civic and political participation in Uganda, we show that political discussion and meeting
attendance increase in districts in which battle events took place, although we do not detect any sizable effect
of the war on formal electoral participation (De Luca and Verpoorten 2011).
In another recent study, Voors et al. (2010) reported that individuals who experienced violence during the
1993-2003 civil war in Burundi displayed more altruistic behavior in the post-war period. Similarly, in a
series of behavioral experiments, Gilligan et al. (2011) find that, three years after the end of Nepal's civil
war, members of communities with greater exposure to violence exhibit significantly higher levels of social
capital, measured by subjects' trust-based transactions and collective good contributions.
On the other hand, another set of recent contributions adds to the more pessimistic viewpoint. First, Cassar et
al. (2011) show how conflict exposure in post-war Tajikistan undermines trust and fairness within local
communities; decreases the willingness to engage in impersonal exchange, and reinforces kinship-based
norms of morality. Second, Rohner et al. (2011), studying the aftermath of the conflict in northern Uganda,
3
reported lower levels of trust and reinforced ethnic identity in the affected districts.
Finally, Bozzoli et al. (2010) studied the impact of conflict on expectations relying on a 2007 survey
conducted in northern Uganda. They found that timing matters: whereas pessimistic expectations prevailed
shortly after the experience of conflict, optimistic expectations were positively related to conflict intensity in
the distant past.
In sum, although most scholars would agree on the importance of understanding the impact of civil war on
different aspects of culture, the scarce evidence available is mixed. Moreover, little is known about the
underlying mechanisms, the persistence of the impact, and the possible heterogeneity of the impact related to
the nature of civil war. This is also stressed by Blattman and Miguel (2010), who, in their recent discussion
on civil war, argue that ³the social and institutional legacies of conflict are arguably the most important but
the least understood of all war impacts.
The distinctive features of the present article are threefold. First, it is the first study on the impact of civil war
on social capital that can rely on two rounds of data compilation, one of which took place before the bulk of
the violence occurred. This unique data set, bracketing a peak in violence of more than 250 battle days in a
year in the affected area, allows us to adopt a difference-in-difference estimation by studying the change in
trust and associational membership upon a continuous treatment equal to the number of district-level battle
days.

Rohner et al. (2011) use the same data sources as we do. However, the two papers are substantially different in focus
and empirical strategy. While we address the effects of conflict on associational membership and generalized trust
during and after the conflict adopting a difference-in-difference estimation, they investigate the effects of the conflict on
ethnic cleavages, trust, and the economic situation in the post-war period.

Second, exploiting the geographic variation as well as the variation in timing of two distinct waves of
violence, we can assess the impact of violence on social capital during the conflict and provide suggestive
evidence as regards the duration of the impact.
Third, it is also worth stressing that the treatment effect we study is different from the treatment considered
in most of the previous studies. Instead of studying the impact of individual-level exposure to violence, we
compare the average change in social capital in areas more or less affected by conflict. In this case, the
treatment is to be interpreted as living in a high-risk, insecure environment; with possible direct exposure to
violence as a witness, victim or perpetrator. Although this community-level perspective may not be helpful in
uncovering the underlying mechanisms, it is important in order to determine whether the heterogeneous
individual-level effects sum up to a general change in social capital. In this sense, our study is
complementary to previous work on Uganda by Blattman (2009).
Although we cannot identify the exact mechanisms underlying our results, it is worthwhile mentioning that
the literature proposes at least three possible mechanisms that link war or trauma to inter-personal relations.
First, in war environments, information acquisition may be costly or imperfect. To save the individual from
the costs of acquiring information, the use of heuristic decis-ofi-on thummakb, ingca stn rategies, or rules
be optimal (Boyd and Richerson 2005). Very concretely, in a highly insecure environment, a general rule of
mistrust may yield the highest payoff. As such rules become entrenched in culture, they may survive the
situation in which they came into existence. For example, Nunn and Wantchekon (2011) rely on this
mechanism to explain the persistent impact of historic slave trade on mistrust in SSA. Second, traumatic
experiences can result in real psychological change impacting in its turn on self-protective behavior and a
change in perception of other individuals (Weinstein, 1989), whereby positive change is not excluded. For
example Collins et al. (1990) show that the ³recognition of one¶s vulnerability´ may enhance the value of
social networks. Finally, if² as argued above² trust is partly the result of social interactions, then a
breakdown of social networks, e.g. community groups, due to displacement or inter- and intra-community
violence, may lead to decreased trust levels (de Jong, 2002).
Our findings indicate that both self-reported trust and associational membership decrease substantially
during the conflict in the affected districts. However, we also find suggestive evidence of a strong recovery
process once the violence has ended. Hence, these findings mediate between the optimistic and pessimistic
viewpoints.
The difference-in-differences estimation method, along with the inclusion of several district- and individual-
level controls, provides a solid base for our empirical analysis. Nevertheless, the potential issue of
endogeneity of conflict intensity remains in establishing a causal effect of violence on social capital.
Violence may be the consequence rather than the cause of decreased levels of trust and participation in
associations, because, for instance, rebel recruitment may be easier in regions plagued by antagonistic
feelings. Although, as argued by Blattman (2009), this is far-fetched in the northern Ugandan context, where
a large share of the Lord's Resistance Army was composed of abducted youths, we adopt distance measures
4
to instrument for conflict intensity following the recent empirical literature on civil war. The IV estimations
broadly confirm the OLS findings.
In the next section, we present the data and provide relevant background information on the armed conflict in
Uganda. In section three, we present our empirical strategy. The results are presented in section four. The last
section concludes.

DATA AND BACKGROUND
Social capital
The data on social capital is taken from the Afrobarometer (AB), an independent, non-partisan research
5
project that measures the social, political, and economic atmosphere in Africa. We use two rounds of AB
survey data compiled in Uganda in 2000 and 2005. We do not use the 2002 and 2008 AB surveys. The 2002
survey does not cover the districts most affected by the civil war, while the questions on social capital
included in the 2008 survey are not comparable to those in the 2000 and 2005 surveys and therefore cannot
6
be analyzed in a difference-in-difference model.
Each survey includes information on approximately 2,400 individuals of voting age. The samples are
nationally representative and geographically stratified across 33 districts in 4 regions, including both urban
and rural areas. Figure 1 gives an administrative map of Uganda in 2000, and Table A1 lists the districts by
region. In Table 1, we give the number of observations per region and per survey year, which show that all
7
four administrative regions of Uganda are well represented in both survey years.

The data and survey instruments are available from www.afrobarometer.org.

Compared to the 2000 and 2005 survey, in 2008 an entirely different set of questions on trust was adopted, and only
two of the associational membership questions were retained.

The four administrative regions are denominated: Central, Eastern, Northern, and Western.

The AB surveys include questions on two interrelated dimensions of social capital: trust and associational
membership. We restrict our analysis to those questions that are comparable across the survey rounds in
terms of question formulation and response categories, which leaves us with five questions - one on trust and
four on membership. The question on trust concerns the respondent's level of trust of others in general and is
formulated as folGleownersal:l y ³speaking, would you say that most people can be trusted or that you must
be very careful in dealing w ith people?
The answer categories are ³You ry mcaustr efbe ul (ve coded asMo 0)st, and people can be trusted (coded
as 1). The questions on membership are introdNowuce Id amas goi fng olto lowread s: ou³t a list of

includes (i) a religious organization like a church or a mosque, (ii) a trade union or farmer's organization, (iii)
a professional or business organization, and (iv) a development association. We code the answer categories
as follows: (0) Not a member, (1) Inactive member, (2) Active member, and (3) Official leader. In the
empirical analysis, we check the robustness of our results against different ways of coding the answers.
A summary of the social capital variables and the different coding is provided in Table 2. We find rather low
levels of trust with less than 20% of the respondents answering that most people can be trusted. Membership
is highest in religious organizations, with more than 80% of the respondents reporting that they were a
member of a religious organization (inactive, active or leading). The other types of organizations only
involve the membership of 20% to 30% of the population. Over time, the reported levels of social capital are
rather stable. On average, generalized trust increases by two percentage points, and membership of a
religious organization increases slightly from 80% to 83%, but these changes are not significant. Larger and
significant changes take place in membership in a trade union/farmer organization (a decrease of 13
percentage points), a professional/business organization (a decrease of 8 percentage points), and a
community development organization (an increase of 6 percentage points). It is noteworthy that there are
large differences across regions despite the relatively small changes in the averages. For example, self-
reported trust increased by 10 percentage points in the western region, while it decreased by 12 percentage
points in the northern region.

The Conflict
The conflict intensity data are taken from the Armed Conflict Locations Events Data (ACLED), which is
based on the screening of news reports and provides geo-referenced information on approximately 3,921
8
violent events in Uganda between 1960 and 2010 (Raleigh et al. 2010).
The violent events include battles between armed groups (2,659) or attacks on civilians (1,262). These events
took place on 1,983 different days within the 50-year period. Hence, on average, a year counts almost 40
event days, and an event day counts 1.98 violent events. The bulk of these event days - more than 90% - took
place after 1995. We situate them on a timeline in Figure 2.
8
The ACLED event data is compiled by screening news articles with language recognition software, which on average
yields good results. However, in some cases press accounts may be biased, because very insecure areas may be difficult
to access or because computer news screening may be sensitive to the language in which events are reported (Restrepo
et al. 2006, Verpoorten in press). Two separate ACLED datasets for Uganda were released, one recording events
between 1960 and 2006, and one recording events between 1997 and 2010. We merged the two datasets and removed
the duplicate observations in the overlapping period 1997-2006.

Figure 2: Event days with LRA and ADF involvement
Figure 2 indicates that, after a period of relative peace following the power seizure by Museveni in 1986, the
number of event days started to rise in 1995. This increase occurred on two fronts. First, in northern Uganda,
the Lord's Resistance Army (LRA), an armed opposition group founded in 1987 by Joseph Kony was able to
9
intensify its activities in 1995 mainly because of support by the Sudanese government (Dolan 2009).
Second, in western Uganda, another armed group² the Allied Democratic Forces (ADF)² commenced its
activities in the mid-nineties. The ADF was a fundamentalist Islamic guerrilla group formed by various
remnant rebels from Uganda, Congo, and Rwanda (Boas 2004). They operated mainly from the Ruwenzori
Mountains bordering with Congo and received support from both the Congolese and Sudanese governments
(Behrend 2007).
In Figure 2, we distinguish between the number of event days with LRA and ADF involvement. Whereas
both groups started to increase their activities in the mid-nineties, the peaks and ends of their activities
occurred at different times. The activities of the ADF were influenced by conflict trends in the neighboring
DRC and were mostly concentrated in the period from 1997 to 2001. By 2002, relative degree of peace had
been established in western Uganda. The bulk of LRA violence, instead, fully unraveled in the period 2002-
2005 following a military operation in southern Sudan by the Ugandan army² the Iron Fis² itn´tended to
destroy the LRA supply bases (Dolan 2009). LRA bases were, indeed, destroyed and many rebels killed.
However, the mission was considered a failure (Allen 2006, Dolan 2009). In fact, LRA forces managed to
outflank the Ugandan army and attacked further south in Ugandan districts until then relatively untouched by
the conflict (e.g., Apac and Lira). Starting from 2006, however, the area of LRA activities first moved out of
Uganda into southern Sudan and into the Democratic Republic of Congo (2006-2008) and then further west
reaching the Central African Republic after 2008 (Accord 2010). This released the pressure on civilians and
opened the way to peace in northern Uganda.

Kony¶s movement gathered armed groups reluctant to settle with Kampala's new government and was initially called
the Lord's Salvation Army, then the United Democratic Christian Forces, and eventually, from 1994 onward, the Lord's
Resistance Army (Allen 2006, Doom and Vlassenroot 1999). The LRA received assistance from Sudan in retaliation for
Ugandan support of a rebel group operating in southern Sudan.

Linking social capital to the conflict
To construct our dataset, we merged the AB data with the ACLED data at the district level, which is the
smallest administrative unit they have in common (the ACLED data is geo-coded but the AB data is not until
2008). Doing so yields a dataset of approximately 4,500 individual level observations across 33 districts. In
what follows, we will use the ACLED conflict data as a treatment to study the change in social capital upon
conflict. Before doing so, three issues have to be discussed.
First, it is evident from Figure 2 that ADF violence peaked before the 2000 AB baseline survey, was still
fairly high in 2001, and then ceased such that by the time the 2005 survey was carried out, ADF operations
had come to an end. Therefore, when we single out the effect of ADF violence we can interpret our results as
the effect of conflict cessation on social capital with respect to the baseline survey collected amidst the
10
violence. In other words, the ADF treatment captures post-war recovery.
Second, although LRA violence escalated after our baseline year, a non-negligible number of battle days
took place before 2000. This pre-2000 LRA activity was largely confined to one particular geographic
region, Acholiland (Kitulgu umdi stand ricts), Gwhile LRA violence outside Acholiland only took off after
2000. Hence, while the estimated LRA treatment should be interpreted as the impact of continued and
escalating violence on social capital, a somewhat cleaner treatment effect can be discerned when focusing on
LRA activities outside Acholiland. This point is illustrated in Figure 3, which gives the number of event days
11
with LRA involvement inside and outside Acholiland for the period 1986-2010.
Figure 3: LRA event days inside and outside Acholiland
Third, that the AB survey was conducted in times of violence as well as amidst a huge refugee crisis
following violence raises the issue of sample selection bias. For instance, because of insecurity, the surveys
may have excluded the most affected individuals in certain districts. In order to verify this, we consulted the
10
In the regression analysis, we evaluate the impact of the ADF battles occurring in the period 2000-2005 on social
capital. In an alternative specification (not reported) we study the impact of the 1995-2000 ADF battles, which gives
similar results (because the spatial variation of ADF battles is very similar across the two periods).
11
Notice that the average intensity of LRA violence experienced outside Acholi districts before 2000 is fairly low, as
the violence reported in Figure 3 was spread across 7 districts (see Appendix A1 for a detailed distribution of violence
by district).

local AB team that conducted the survey. We learned that, when an enumeration area within a district was
highly insecure, the enumeration area was replaced by a more secure area within the same region. The
substitution always followed the composition of the original sample in terms of language and ethnicity as
well as the direction of displacement of the individuals in the original sample, often ending up with a sample
of within-district internally displaced people (IDP) (correspondence with Francis Kibirige 2011). This
approach was facilitated by the maintenance of local administrative structures in the IDP camps and also by
the moving of the IDP within their own district. Given this approach and given the fact that more than 90%
of the population was living in these local IDP camps, we can be fairly confident that the AB survey is
12
representative at the district level for each survey year.
Moreover, since substitution was confined to highly insecure areas, it basically would only cause potential
bias for the impact of LRA violence in Acholiland. Results for other violent events, e.g. the LRA battles
outside Acholiland, would not be affected.
Finally, to cross-check the ACLED data and verify whether it indeed is in line with individual-level
perceptions of violence of the respondents, we examine the following question that was included in the 2005
AB survey: Please tell me if the following things are worse orw byeaetrs tagero, nowor than they were a fe
are they about the same: Safety from crime and violence?. We code the answer to this question as follows:
(1) Much better, (2) Better, (3) Same, (4) Worse, (5) Much worse. Given the trends in the LRA and ADF
events described above, we expect respondents in LRA-affected districts to report worsening safety
conditions, while we expect the reverse for respondents in the ADF-affected districts. This is exactly what
we find. We find a positive and significant correlation between the LRA treatment (LRA event days in 2000-
5) and the respondents perception of the trend in violence and crime, indicating that, in line with the rising
trend in ACLED events in LRA districts, the respondents perceived an increase in violence. In contrast, we
find a negative and significant correlation between the ADF treatment (ADF events in 2000-2005) and the
respondents¶ perception of the safety situation, indicating that the ADF treatment corresponds with a decline
in violent events over time.
EMPIRICAL STRATEGY
To identify the impact of violence on social capital, we use a difference-in-difference estimation that exploits
variation in the event days across districts and over time. The treatment is a continuous variable equal to the
event days occurring between the implementation of the 2000 and 2005 AB surveys. The treated group is the
households located in the districts where the battles and attacks took place. In other words, the empirical
identification strategy relies on the comparison of the change in social capital in 2000-2005 across areas with
low violence intensity and areas with high violence intensity.
Formally, the empirical model can be written as follows:

indicator variable taking one for respondents in the 2005 survey. Thus, the coefficient of interest is Ù7, which
is the coefficient of the interaction term between $× and UAç. =NTo reduce heterogeneity across the

Both variables may affect the level of trust in the baseline year. All explanatory variables are summarized in
Table 3. In a series of robustness checks reported at the end of this paper, we show that these district-level
controls are not critical for our results.

Finally, ßå denotes regional fixed effects, which are included to capture region-specific unobserved factors
that may affect social capital and ÝÜáçá× is the standardized error term. In order to account for a potential
correlation of these errors within districts and within years, we adjust the standard errors for two-way
clustering as suggested by Cameron et al. (2006).
Since the answer categories for the social capital questions in the AB surveys are categorical, we have the
option between two different estimation strategies. First, we can maintain the categorical nature of the
answers and estimate an ordered probit model. Second, we can estimate our empirical model by OLS,
treating the categorical answer as if they were part of a continuous scale. We use the latter approach in the
14
baseline result and report the former as a robustness check.
To account for the different timing of the violent events, we estimate an expanded model in which we
distinguish three different types of violence: LRA violence in Acholi districts (LA), LRA violence in non-
Ý
Acholi districts (LN), and ADF violence (AD). Formally, we replace $× in the previous equation by $×, with
j=(LA,LN,AD) denoting the type of violence, obtaining:

where Ù9, Ù:and Ù; are the coefficients of interest. In this specification, the vector :çá× also includes the
interaction term of ethnic fractionalization in 1991 and the 2005 year dummy. By doing so, we can rule out
that the differential impacts we may find across the three types of violence are due to different degrees of
ethnic heterogeneity across the affected districts. Again, this district-level control is not critical for our
results.
As noted above, LRA activities exploded in 2002 but affected northern districts already before 2000, albeit to
ź
a lesser degree. Hence, we interpret the coefficient Ù9 on the interaction term $×ÛUAç =Nas the effect of
additional and escalating violence on social capital. The LRA activities reached further south only after 2002,
ÅÇ
which allows us to interpret Ù: on the interaction term $×ÛUAç =Nas the impact of violence on social
capital relative to a situation without a direct confrontation with violence. Finally, the coefficient Ù on the
:
º½
interaction term $ÛUAç =Ncaptures the change in social capital when moving from a situation amidst
×
violence into a post-war phase.
With respect to these coefficients of interest, we formulate two intuitively appealing hypotheses:
Hypothesis 1: Both the start and the escalation of LRA violence reduce social capital. Ù9
O and Ù:
O .
Hypothesis 2: The ending of ADF violence is associated with an increase in social capital. Ù:
P .
Thus, we hypothesize that violence reduces social capital and that, once the violence ends, social capital
recovers. It is much less intuitive to conjecture about the relative magnitude of the coefficients. For instance,
if the start of violence reduces social capital more than the escalation of violence, then Ù9
OÙ:. On the
other hand, if the escalating violence reaches a very high intensity, the reverse may be true: Ù9
PÙ:.
As already mentioned, the AB survey was conducted when violence was on going as well as amidst a huge
refugee crisis. In the districts most heavily affected by the violence were districts the vast majority of the
population was living in local IDP camps. When interpreting our results we are unable to disentangle the
effect of facing violence from the effect of living in an IDP camp. However, since both experiences are often
14
One advantage of using OLS is that it allows us to estimate the standard IV model. This is also the approach taken by
Nunn and Wantchekon (2011) in their analysis of the AB trust data.

emerging together in civil wars, we believe that identifying their joint effect is valuable and enhances our
knowledge on the impact of civil wars.
EMPIRICAL RESULTS
Baseline results
Table 4 shows the results of estimating our first equation, i.e., when all types of violence (LRA and ADF
event days) are pooled together. There are no sizable effects of violence on the level of generalized trust and
on the associational membership, except for a significantly negative impact on membership in religious
organizations. However, as argued above, it is more appropriate to separate ADF- and LRA- related violence
as well as LRA violence inside and outside Acholiland.
Table 5 shows the estimation results of our second equation when the three types of violence are
distinguished. Consider first the treatment effect associated with LRA violence in Acholiland. The estimated
coefficient Ù9 indicates a decrease in associational membership (Columns 2-5), but no significant impact on
generalized trust (Column 1). The estimated treatment effect of LRA violence outside Acholiland, Ù:,
indicates a significant decrease in generalized trust as well as associational membership of religious groups
and community/development organizations but is insignificant in explaining the change in membership in
economic associations (trade/farmer & professional/business). The magnitude of the impact is substantial: for
instance, according to our estimate in column (1) a 1% increase of LRA battle days outside Acholiland leads
to a decrease in generalized trust of 0.025, which is a sizable effect considering the average generalized trust
of 0.15 for the whole sample in 2000 (see Table 3). Similarly, a 1% increase of LRA violence outside

Acholiland reduces participation in community/development organizations by 0.047, relative to the average
15
of 0.56 for the whole sample in 2000.
Finally, for ADF violence, we find a positive and significant impact for all social capital variables considered
(Ù;
P ), indicating that individuals living in the ADF-targeted districts reported higher levels of trust and
greater involvement in all types of association in peaceful 2005 than in war-torn 2000.
Overall, these results are in line with Hypotheses 1 and 2 formulated above. Hypothesis 1 is, however, only
partially confirmed since Ù9, although negative, is not estimated significantly different from zero in

trust Ù9
OÙ:, indicating that the start of LRA violence was more detrimental to trust than its escalation.
The pattern is reversed for associational membership, where we find that Ù9
PÙ:. As pointed out above,
one explanation may be that the escalating LRA violence inside Acholiland reached epic proportions. In fact,
in the period 2000-2005, the number of event days in an Acholiland district was more than five times as high
than the number of event days in an LRA affected district outside Acholiland (see Table 1). The
concentration of intense fighting in Acholiland triggered a large refugee crisis, which may have disrupted the
associational life of its residents. In contrast, associational life outside the Acholi districts may have been less
affected given the lower exposure to intense violence and the lower degree of population displacement.
Robustness checks
We perform three types of robustness checks. First, we test if our results hold in subsamples of the AB data.
Second, we check whether our results are robust with respect to the use of alternative estimation models and
alternative definitions of the main variables of interest. All these results are condensed in Table 6, in which
we report only the coefficients for the interaction terms of interest. Third, to tackle potential endogeneity
issues (for instance, conflict events may be measured with error), we repeat our estimates instrumenting for
the different types of violence.
16
Beside the different timing of the violence, the three types of violence were also characterized by differences along
ethnic lines. In particular, the LRA was composed by Acholi individuals, and perpetrated violence against people
belonging to the same ethnic group when operating in Acholi districts, and against other groups when operating
elsewhere. The ADF was more heterogeneous in terms of ethnic composition as were their targeted victims. Rohner et
al. (2011) dig further into these issues.

Subsample analysis
Our empirical strategy relies on the comparison of the change in social capital between individuals living in
heavily war-affected districts and individuals living in less affected districts. Thus, these latter districts are
used to proxy the counterfactual: what would have happened if violence would not have taken place? This is
a valid approach if both groups of districts are broadly comparable in terms of other potential determinants of
the change in social capital. To put this approach to a test, we estimate our empirical model for two
subsamples of broadly comparable districts: (1) a sample including only the northern area to test the impact
of the LRA violence and (2) a sample only including the southern area for testing the impact of the ADF
violence. The former is a rather radical test since it leaves us only with one third of the sample observations.
This north-south division of the sample follows the division of Uganda along ethnolinguistic lines: the
southern part is exclusively Bantu, whereas the northern part is almost exclusively of Nilotic origin. In Table
A1, we indicate the districts with Bantu origin based on Lewis (2009). The results, reported in the first two
panels of Table 6, are qualitatively the same as our baseline results with one exception. For non-Acholi
districts, the impact on generalized trust loses significance, which may be due to the drastic reduction in the
sample size.
Alternative estimation models and variable definitions
We first estimate a more parsimonious model that excludes the district level controls (historical battles,
ethnic fractionalization and the interaction term between the latter and the 2005 survey dummy). The results,
reported in the third panel of Table 6, are qualitatively the same as the baseline results except for the impact
of LRA violence in Acholiland on general trust, which is now estimated to be significantly negative (instead
of insignificant).
Second, since the responses to the AB questions on trust and membership are categorical in nature, a sensible
robustness check consists in replicating the estimations using the original categorical nature provided by the
AB. Using an (ordered) probit model produces estimates that are qualitatively identical to our baseline OLS
estimates.
We also estimate our empirical model using probit with an alternative binary coding for our dependent
variables (see Table 2 for details on the codes). The results are given in the fifth panel of Table 6: 13 out of
the 15 coefficients of interest remain qualitatively identical, and the remaining two coefficients lose
significance but do not change sign.
Finally, we repeat our main specification measuring conflict intensity in two different ways (instead of the
logged number of event days): (1) by the number of event days, and (2) by the logged number of events. The
results ± displayed in the last two panels of Table 6 ± do not change qualitatively except for the impact of
LRA violence in Acholiland on the generalized trust level, which is now weakly significant (instead of
insignificant).

As excluded instruments, <, we use the 1991 district-level population share of Acholi, the distance to
×
Sudan, and the logged distance to the Ruwenzori Mountains. The first of these instruments captures LRA
17
violence, which was directed mainly against the Acholi.
The second instrument is relevant because, as part of the Sudanese support for the LRA rebels, the LRA was
provided with logistics and bases on Sudanese territory from where they organized raids. Finally, since ADF
bases were located in the Ruwenzori Mountains, where rebels could easily hide and be supplied from the
DRC, we expect the distance to these mountains to be highly correlated with the location of ADF operations.
17
The LRA was constituted by people of Acholi origin. Nevertheless, LRA received little support among the Acholi
population as it resorted to looting and youth abduction to sustain itself. The situation worsened further when the
government started to organize self-defense militias in Acholi districts. The LRA leadership tagged this decision as
betrayal and launched a campaign of killing and mutilation of Acholi civilians to dissuade further collaboration with the
government army (Behrend 1999, Branch 2005).

from zero when instrumenting for the interaction terms (columns 7-9). The relevance of our instruments is
confirmed by the Kleibergen-Paap test for underidentification. The second stage results are qualitatively very
similar to the OLS results for most of the social capital variables, suggesting that endogeneity is absent and
our results can be interpreted as causal. The only noteworthy change concerns the impact of LRA violence in
Acholiland on trust, which is now estimated significantly negative (instead of insignificantly negative).

The F-statistics of all first stage regressions are larger than 100. In interpreting first stage results, notice that each
instrument is meant to predict one particular type of violence. This explains why, for instance, the share of Acholi
population displays a negative sign when predicting violence outside Acholiland, and a positive sign when predicting
violence inside Acholiland.

CONCLUSIONS
We analyzed the impact of armed conflict in Uganda, making use of two nationwide surveys that not only
bracket the peak in LRA violence taking place in the north of the country, but also capture the transition from
violence to peace in the west in the aftermath of ADF violence. In sum, our findings indicate that social
capital decreases amidst violence. However, in line with several previous findings, we also document that
social capital strongly increases in the post-conflict phase.
More specifically, we find that both the level of trust and participation in religious and community
associations decreases when transiting from relative peace to violence. Regarding participation in economic
associations (farm, trade, business and professional voluntary organizations), the negative impact of violence

is confined to Acholiland, where the conflict was most disruptive as the majority of the population was living
in IDP camps to protect themselves from LRA attacks.
On a more positive note, our results suggest a strong post-violence recovery process. A few years after the
end of the ADF-related violence, the level of trust dramatically increases in the affected areas, and
participation flourishes in all the types of voluntary organizations considered. It is difficult to assess to what
extent this result can be generalized. For instance, a rapid post-conflict recovery of social trust may not occur
in areas targeted by LRA operations because, contrary to the ADF-affected region, the LRA-affected areas
remained largely excluded from power in the aftermath of the conflict, a factor that may play against the easy
restoration of trust.
How do these findings fit with the literature? At this stage, the evidence from existing studies balances
between a positive and a negative civil war impact on social capital. So does our study, which suggests that
much may depend on the time span between the measurement of social capital and the end of violence. In
addition, the overall community-level effect may depend heavily on what proportion of the community was
directly exposed to violence as a witness, perpetrator or victim, and what part of the community was only
indirectly affected, e.g. by displacement and fear.
Although we control for a large set of individual- and district-level covariates, and although our results are
stable throughout a number of robustness checks, and after controlling for possible endogeneity and
attenuation bias, these results remain tentative. First, this is obviously not an experimental setting and the
econometric techniques used cannot fully substitute for the unobserved counterfactual: what would have
happened in the absence of violence? Second, many questions remain unanswered. What are the precise
mechanisms underlying our results? Does social capital bounce back to its pre-war level, fall behind or even
exceed it? How can these results be generalized to other settings with violence of different forms and
duration? To answer these questions, more data points are needed from more countries on more forms of
violence.
