War costs and public support for domestic counterinsurgency: Evidence from Thailand Bethany Lacina Assistant Professor, Department of Political Science, University of Rochester PO Box 270146 Rochester, NY 14627-0146 585-273-5842 (phone) 585-271-1616 (fax) [email protected] Spring 2016 Abstract When does public opinion support domestic counterinsurgency? Do the costs of conflict breed war weariness, increasing support for compromise? Or does violence harden support for war? I examine country-wide opinion polling from Thailand concerning government policy toward insurgency in the south. The perceived severity of insurgency predicts greater support for southern autonomy. That relationship is driven by respondents outside of the conflict theater, however. The number of military fatalities associated with a respondent’s regional army is also positively correlated with support for southern autonomy. As placebo tests, I demonstrate that neither perceived conflict severity nor military fatalities predict greater support for reconciliation in the simultaneous conflict at the capital. Together, the results suggest Thai public opinion on domestic counterinsurgency is subject to a casualty fatigue process similar to overseas wars but rarely applied to civil conflict. Word count: 9805 When does the public support domestic counterinsurgency? As the costs of a civil war mount, do citizens demand the government compromise? Both scholars and policymakers believe that the costs of overseas wars can create a popular backlash against continued military operations. This “casualty fatigue” or “war weariness” pattern has been extensively studied in the United States and Europe. Does a comparable process influence public opinion during a domestic conflict? Much of the literature on civil war and counterinsurgency implies that the answer is no. Public opinion radicalizes during civil violence, partly but not solely due to personal exposure to violence. Deepening hatreds and intolerance are one reason civil wars tend to be much longer and more likely to recur than international wars (Collier et al., 2003). This article investigates public support for domestic counterinsurgency using polling from Thailand in 2010. I find that the perceived severity of conflict in southern Thailand is positively correlated with support for greater southern autonomy. This pattern is consistent with war-weariness. However, the correlation is only apparent among respondents living outside the conflict theater. War weariness may be most relevant as a model of public opinion when conflict is spatially isolated and the policies at issue have limited national ramifications. I conduct two investigations to demonstrate the credibility of the war-weariness finding. First, I create a placebo test, showing that perceived costs of the southern conflict do not increase support for compromise in the contemporaneous conflict at the capital. Second, I take advantage of the regional structure of the four commands of the Royal Thai Army. I show that the number of military fatalities associated with a respondent’s regional army is positively correlated with support for compromise in the south. In this article I make two contributions. The first is to contrast two research programs on public opinion and war costs, one from overseas wars and one from domestic wars. By presenting and investigating both programs, I make the first step toward determining the conditions under which each model of public opinion is most likely to apply. Second, the case of Thailand brings the research on public opinion during internal war to a previously-neglected type of conflict. Studies of opinion polling in civil war disproportionately concern small countries where war fighting has 1 directly affected a large share of citizens. Here, I examine the more common scenario of an internal conflict that is geographically peripheral and personal experience of violence is relatively rare. I find a difference in reactions to war costs between in- and out-of-theater respondents, with only the latter group conforming to a conflict fatigue model. I gauge the plausibility of this conflict fatigue finding with placebo tests and by examining the relationship between military fatalities and public opinion in a subsample of my data. I conclude by arguing that the casualty fatigue hypothesis may be the best model for understanding out-of-theater populations’ support for domestic counterinsurgency. Conflict cost and public support for war Two literatures study popular reaction to war: the first on overseas military campaigns, the second on counterinsurgency and civil war. Data from overseas war show a remarkably consistent relationship between the costs of conflict and decreased support for military action. Total casualties, adverse trends in casualties, and individuals’ social and spatial proximity to casualties all depress support for overseas military operations. By contrast, much of the commentary and scholarship on civil war implies that the public becomes more belligerent as war continues. Overseas conflict: Costs create war-weariness In the study of public support for foreign war, the implicit model is one of citizens weighing the costs and benefits of continued conflict (Gartner, 2008a; Gartner and Segura, 1998; Mueller, 1973): Actual or “objective” information regarding the costs and benefits of war is carefully weighed by an individual before he or she forms attitudes regarding the legitimacy of the war, the long-term prospects for success, the worthiness of the goals of the intervention (Boettcher and Cobb, 2006, 838).1 1 This updating process is subject to individual biases and framing effects (Althaus et al., 2012; Boettcher and 2 As the costs of war, especially casualties, accumulate, individuals revise their estimates of the total costs of war upward and update their beliefs about the likely ultimate success of war (Eichenberg, 2005; Gelpi et al., 2005, 2009). Some people place such a low or high value on the outcome of the conflict that new information about costs or the probability of success cannot shift their views. On average, however, the accumulation of casualties and an increasing rate of casualties depress public support for war (Gartner and Segura, 2008).2 US political elites also respond to war time casualties, especially casualties in their constituency, by decreasing support for war (Gartner, 1997; Murray, 2001; Myers and Hayes, 2010). US respondents respond most to costs befalling their families and acquaintances (Davenport, 2015; Gartner, 2008b). Spatial proximity to families of the deceased also matters. For example, individuals living closer to the families of deceased soldiers were less likely to support the Vietnam War (Gartner et al., 1997; Gartner and Segura, 2000) and the second Iraq war (Althaus et al., 2012; Hayes and Myers, 2009). In US elections, voters’ punishment of incumbent politicians is conditioned by local war casualties rather than national casualties (Gartner and Segura, 2008; Gartner et al., 2004; Grose and Oppenheimer, 2007; Karol and Miguel, 2007; Kriner and Shen, 2007). War weariness in civil war? In civil war, does violence impress individuals with the costs of conflict and thereby reduce their support for war? Some theoretical and empirical literature implies it does. During the Vietnam War, Leites and Wolf (1970) portrayed civilians making cost/benefit calculations in determining support for rebels and governments.3 There is also some empirical evidence that internal war Cobb, 2006; Gaines et al., 2007; Johnson and Tierney, 2006), as well as equity concerns (Johns and Davies, 2014; Kriner and Shen, 2014; Kull et al., 1997). A critique of war weariness arguments holds that public support for war follows cues from elected officials and the media (Baum, 2002; Baum and Groeling, 2010; Berinsky, 2007; Jakobsen and Ringsmose, 2015; Pevehouse and Howell, 2007). 2 On casualties and voter turnout, see Koch and Nicholson (2015). 3 See also Mason (1989). 3 produces civilian war weariness. During the US Civil War, Congressional incumbents lost more votes in districts with more local casualties (Carson et al., 2001). Blair et al. (2013) fielded an endorsement experiment to measure support for insurgents in Pakistan. They found disaffinity for insurgents among poor, urban Pakistanis but only in districts that suffered insurgent violence in the last year. They interpret this pattern as evidence “that exposure to terrorist attacks reduces support for militants” (30). Nonetheless, treatments of internal war (Kilcullen, 2009; Mason, 2004) and counterinsurgency doctrine (US Armed Forces, 2006) more often presume that civilians become more belligerent in response to the costs of civil war, especially government repression. Both insurgents and their supporters frequently report government violence as a reason for their own conversion to the militant cause (Askew and Helbardt, 2012; Mahmood, 1996; Popkin, 1979; Wood, 2003). Violence by non-state actors receives less attention but may also be radicalizing. Some of this radicalization reflects personal exposure to violence.4 However, the connections between personal experience of violence and policy views are not straightforward, thanks to the role of other predispositions and policy beliefs (Longo et al., 2014; Lyall et al., 2013). Personal experience of violence is, in any event, only one component of public opinion during civil war. Most civil wars only directly involve a small portion of a country’s population and territory (Dittrich Hallberg, 2012). Yet, the polarizing effect of civil war on public opinion is thought to be much broader. For example, the World Bank’s famous report on “conflict traps” hypothesized that one reason civil war is more common in countries that have already had a prior war is that conflict “intensifies hatreds” (Collier et al., 2003, 87): . . . hatreds build up during periods of violence, leaving the society polarized. People on both sides want vengeance for atrocities committed during the conflict and these may supplant any prior grievances (88). 4 Bakke et al. (2009); Bellows and Miguel (2009); Blattman (2009); Canetti-Nisim et al. (2008, 2009); De Juan and Pierskalla (2016); Voors et al. (2012). Some research suggests community-building effects of trauma (Bellows and Miguel, 2006, 2009; Blattman, 2009; Voors et al., 2012). 4 Sambanis and Shayo (2013) formalize this intuition, arguing that violence can reinforce conflictual identities and undermine shared identity. Supporting that thesis, Tir and Singh (2015) use the World Values Survey to show that social intolerance is higher in countries that have experienced secessionist wars.5 The targets of this intolerance were all out-groups, not only the ethnic group(s) on the opposite side of the recent civil war. Hutchison (2014) finds that civil conflict reduces public support for civil liberties of non-conformist organizations. Multiple studies of public opinion in Israel imply that Jewish Israelis have become more opposed to compromise with Palestinians in response to violence or perceived threat (Berrebi and Klor, 2008; Canetti-Nisim et al., 2008, 2009; Maoz and McCauley, 2009; Shayo and Zussman, 2011). War costs and support for domestic counterinsurgency In sum, the hypothesized effect of conflict costs on public support for war is very different in the literatures on overseas and on civil conflicts. A few studies on civil conflict find evidence that war costs push the public toward peace but, in the main, scholars have argued the opposite. Studies of public opinion during civil war have been disproportionately drawn from Israel. Afghanistan, Burundi, Pakistan, the Caucasus region in Russia, Nepal, Sierra Leone, and Uganda are also represented. Based on that list, conflicts over control of the central government have been studied more often than conflicts over territorial autonomy or separation. Existing studies also come disproportionately from wars with extensive involvement by foreign militaries, from geographically small countries, and from wars that had a relatively large conflict theater. The next section turns to the context for this study, the war over ethnoterritorial autonomy in southern Thailand. Compared to other civil conflicts where public opinion has been studied, this war is not very internationalized and directly affects a limited portion of the country’s territory and citizens. 5 They found no changes in social tolerance after non-secessionist wars. 5 Pattani Malay insurgency in Thailand Thailand’s southern provinces of Yala, Narathiwas, and Pattani (see Figure 1) are ethnically and religiously distinct from the rest of the country.6 About 80% of the population in these three provinces speaks Pattani-Malay (also called Yawa) as a first language, while Thai is the dominant language elsewhere. Almost all Pattani-Malays are Muslims, while Thailand as a whole is 90% Buddhist. The neighboring district of Songkhla has a small population of Pattani-Malay Muslims concentrated along the border with Pattani and Yala. Yala, Narathiwas, Pattani, and Songkhla’s border districts were once the sultanate of Patani (Haemindra, 1976).7 The current insurgency emphasizes this regional Pattani-Malay identity over Muslim identity. Although there are Thai- and Chinese-ethnicity Muslims in southern Thailand, the insurgency is exclusively oriented toward Pattani-Malay Muslims. A separatist insurgency in the 1960s and 1970s presaged a new phase of southern violence beginning in the early 2000s (Funston, 2008). A new phase of southern violence began in the early 2000s. In 2004, militants made a successful surprise attack on an army base, gaining national and international attention. The insurgents were highly fractionalized and, through 2010, had no identifiable organization or leadership with credible control over rebel violence (Funston, 2008; Liow and Pathan, 2010). Power Vacuum McCargo (2008) and Mahakanjana (2006) argue that the proximate cause of conflict was a power vacuum created by Thaksin Shinawatra, Thailand’s elected prime minister between 2001 and 2006. Thaksin is notable for being a member of the country’s Sino-Thai nouveau riche, as opposed to the traditional political elite mostly descended in some way from the royal family. 6 Figure 1 based on GADM (2012) and census region definitions from National Statistical Office (2010). district, to the west of Songkhla, is 70% Malay-speaking Muslims but was not a part of the Patani sultanate (Funston, 2008, xiii). 7 Satun 6 Figure 1: Thailand’s four census regions—north, northeastern, central and southern—and its southernmost provinces N NE C Bangkok S Songkhla Pattani Yala Narathiwat Thaksin attempted to build a political following in the far south by dislodging bureaucrats and military personnel affiliated closely with the monarchy. In 2002 Thaksin dissolved the Southern Border Administration Center (SBPAC) and Civil-Military-Police Task Force 43 (CMP-43), unelected bodies that coordinated military and civil service activity in the south (Funston, 2008, 25). Responsibility for southern security was transferred from the military to the national police. Neither the SBPAC nor CMP-43 had provided regional political autonomy, but they did serve as a means for central officials to consult with and coopt Pattani Malay elites (Mahakanjana, 2006). The military also maintained a network of informants inside separatist outfits in the south. When the police took control of southern security, approximately 20 of these informants were killed, allowing the insurgency space to grow (McCargo, 2008, 115). The second piece of Thaksin’s plan to build a following in the south was to forge a relationship with the largest Pattani Malay political party, called Wadah, headed by Wan Nor (Wan Muhammad Nor Matha). In 2002, Wadah joined Thaksin’s party and Wan Nor became interior minister. However, alignment with the government undermined Wadah’s popularity by implicating it in state repression, especially a 2004 raid on the Kru-Ze mosque in Pattani and dozens of protestor deaths in military custody after a 2004 demonstration in Tak Bai, Narathiwat. Thus, both pieces of Thaksin’s strategy to gain a political following in southern Thailand—police-led security and the Wadah alliance—faltered. Counterinsurgency policy Between 2004 and 2010, successive Thai governments had a consistently hardline response to insurgency. Thaksin increased force deployments in the south and rejected any talk of political compromise (Albritton, 2006). After a 2006 coup, the military government reestablished the SBPAC and a joint civil-military-police command for the south, but with greater military dominance of each (Funston, 2008, 25). Emergency laws gave the military impunity from prosecution for deaths in custody and torture. The military’s leading role was not countered by the next two civilian 8 governments: a Thaksin-aligned government elected in 2007 or the anti-Thaksin Democrat Party government that took power in 2008 (Abuza, 2011; Dalpino, 2011). Instead, both governments were preoccupied by the “colored shirt” protests in Bangkok, described below. Throughout the 2000–2010 period, the Thai central elite steadfastly opposed autonomy for southern Thailand, even in limited forms such as an elected governor. (Thailand is a unitary state with unelected provincial level governments).8 Bangkok’s resistance to autonomy was embodied in a National Reconciliation Council (NRC) appointed in 2005: Reporting in June 2006, [the NRC] made a series of modest proposals for improving the quality of justice, security, and governance in the deep South . . . The NRC’s proposals were considered too progressive by most government officials but did not go nearly far enough for most Malay Muslims. The NRC refused to engage seriously with ideas of substantive decentralization . . . let alone any proposals for different forms of autonomy (McCargo, 2008, 10).9 Gunaratna and Acharya (2013), rightwing analysts who oppose southern autonomy (174), also admit that there was no political will in the capital to implement the NRC’s recommendations and that powerful conservatives in the government immediately moved to quash the NRC’s tangible recommendations, such as the recognition of Malay as a “working language” in the south (156– 157). While central elites have taken a hardline against southern autonomy, the public has been disengaged from the southern conflict, according to most analysts. Albritton (2006) wrote that in 2005 “A majority of the population . . . is largely oblivious to the ongoing conflict” (172). As turmoil in the capital increased, Prasirtsuk (2009) observed that “The conflict in Thailand’s south continues but has been eclipsed by the political crisis [in Bangkok]. The southern insurgency rarely made headlines in 2008.” (183). The same indifference was reported in 2010: “Although violence in the 8 The 9 See exceptions are Bangkok and Pattaya City, both in central Thailand. also McCargo (2012, chp. 4). 9 Muslim South, targeting teachers and other community leaders, did not diminish in 2010, the lack of progress had little impact on the government’s standing in other regions of Thailand” (Dalpino, 2011, 160). Quotes like these underline that civil conflicts can be spatially isolated and of limited nationwide salience. These circumstances suggest an analogy to overseas war and the possibility that casualty fatigue is a useful means of understanding public support for ongoing COIN. On the other hand, the salience of Thailand’s southern conflict was apparently so low that its costs may not register in public opinion. Survey of Thailand, 2010 The Asia Foundation (TAF) fielded a national survey with 1,800 respondents from September 17 to October 23, 2010 (Asia Foundation, 2011). The study included 300 respondents from Narathiwas, Pattani, and Yala, 100% of whom were self-reported Pattani Malays.10 Narathiwas, Pattani, Yala, and Bangkok provinces were designated for inclusion in the survey prior to further sampling. Investigators drew a random sample of the remaining provinces in the country, stratifying based on the four regions used in the census of Thailand (Figure 1): north, northeast, central, and south.11 Within provinces, an equal number of rural and urban respondents were sampled, except in Bangkok, which is entirely urban. Thus, respondents’ sampling probabilities depended on their census region, province, and rural versus urban location.12 My dependent variable taps public support or opposition to the government’s counterinsurgency policies with a question about autonomy as a conflict-resolution measure. TAF asked respondents: “Some have suggested that political decentralization or limited autonomy (but not territorial 10 Some villages in the three southern provinces were omitted from the sampling frame due to insecurity. A.1 in the Supplemental Materials shows the surveyed provinces. 12 Sampling weights provided by TAF also reflect sex and respondents’ age cohort, presumably to adjust for nonresponse. Throughout the analysis in the main text, I use these survey weights and cluster observations by sampling strata when calculating standard errors. I report results based on unweighted and unclustered data in the Supplementary Materials (Tables A.8 and A.11). Pattani Malays are over represented and rural respondents are under represented in the unweighted sample. See the summary statistics for weighted and unweighted data in Tables A.1–A.7. 11 Figure 10 separation) might help resolve the long-term conflict in southern Thailand. Do you agree or disagree?”13 Given the entrenched government resistance to autonomy, respondents who agreed that autonomy might resolve conflict were deviating sharply from Bangkok’s counterinsurgency strategy. Outside of the three deep south provinces, 63% of respondents endorsed southern autonomy in response to this question, indicating substantial dissent from the central elites’ military-driven COIN strategy.14 75% of Pattani respondents endorsed autonomy as a means to end conflict. I measure the key independent variable, respondents’ beliefs about the costs of the conflict in the south, based on replies to an open-ended question regarding Thailand’s biggest problems. Respondents were asked, “In your view, what is the biggest problem facing Thailand?” I code High perceived conflict costs as a 0/1 variable, with a value of 1 for respondents who described conflict in southern Thailand as the country’s biggest problem. Not surprisingly, given central government turmoil at the time, only a small number of respondents—4%—listed conflict in the south as the country’s gravest problem. The most common answer was political conflict in the capital (43%), followed by economic problems (33%). A plurality of Pattani Malay respondents put the conflict at the center (35%) at the top of their list of problems but conflict in the south was the second most frequent answer (24%). The wording of this question is unfortunate because it does not capture the full range of variation in the perceived costs of southern conflict. Instead, the question only identifies respondents who thought those costs were high enough to eclipse other problems in Thailand. In the appendix, I use an alternative measure of perceived conflict severity (Tables A.10 and A.12); the results support the findings in the main text. Survey respondents were asked whether the country was headed 13 The full text of all survey questions is provided in the Supplementary Materials. This question taps both respondents’ willingness to see autonomy in the south and beliefs about its efficacy as a conflict-resolution measure. Studies of casualty fatigue using observational data have difficulty distinguishing beliefs about the desirability of outcomes from beliefs about what is likely to happen if the government tries one policy versus another. Only experimental studies have thus far been able to parse that distinction (e.g., Gelpi et al., 2005, 2009). 14 A 2009 TAF survey of the same population found 48% support for autonomy (Meisburger, 2009, 50). Gunaratna and Acharya (2013) report two national surveys from 2005 in which a majority of respondents opposed martial law in the south and the punitive security zone system the government was implementing at the time (153). 11 in a positive or negative direction and then asked to explain why they thought so. The latter question was open-ended and the enumerators recorded up to six responses. I used respondents’ lists of problems to code a second measure of perceived conflict costs: whether the respondent listed the southern conflict as one reason for pessimism about Thailand. This variable is available only for respondents who thought Thailand was headed in the wrong direction, although this is the majority of respondents (61%). In that subset, about 10% cited the conflict in the south as a reason Thailand was headed in the wrong direction, including 8% of non-Malays and 33% of Malays. Perceived costs and support for southern autonomy Table 1 examines the relationship of perceived conflict costs with support for government compromise in a domestic COIN context. Model 1 reports a bivariate logistic regression of Thai respondents’ perceptions of the costs of conflict in the south as a predictor of support for southern autonomy.15 The correlation is positive and statistically significant. The estimated coefficient (1.0) translates to an odds ratio of 2.7. To interpret that figure, consider that the average rate of support for southern autonomy in the data is about 60%. If the corresponding odds are multiplied by 2.7, the probability of support goes up to about 80%. Table 1 continues with multivariate models of the relationship between perceptions of the severity of southern conflict and endorsement of southern autonomy. Model 2 includes a dummy variable for Pattani Malay ethnicity and measures of respondents’ age, sex, education, income, and whether they live in an urban or rural area.16 After adding these controls, the magnitude of the 15 In order to estimate these models and the models in Table 2 on the same sample, I excluded respondents who answered the southern autonomy question but not the questions on protestor pardons described below. In the Supplementary Materials, I include these respondents in an analysis of support for southern autonomy and find results similar to those in the main text (Tables A.9 and A.15). 16 Age is a continuous scale ranging from 2 (18-19 years old) to 11 (Above 80 years old). Education is captured as dummy variables for secondary/vocational education and for post-secondary education. TAF used different income scales for urban and rural areas and for Bangkok, in each case ranking a respondent from one to nine. I use these rankings as a continuous measure, reflecting respondents’ incomes relative to their communities. 12 Table 1: Logistic regressions of respondent support for southern autonomy as a conflict resolution measure and perceived costs of the southern conflict Model 1 Model 2 Model 3 Model 4 Model 5 1.0∗ (0.37) 1.0∗ (0.37) 1.1∗ (0.39) 1.5∗ (0.39) 1.6∗ (0.42) 0.37 (0.33) 0.23 (0.36) 0.63 (0.35) 0.50 (0.40) -1.6 (0.86) -1.6 (0.90) High perceived conflict costs Pattani Malay Costs*Pattani Malay Favors decentralization 0.91∗ (0.15) 0.92∗ (0.15) Military role too large -0.084 (0.16) -0.092 (0.16) Satisfaction w national government 0.13 (0.11) 0.12 (0.11) Age 0.0070 (0.031) 0.0019 (0.033) 0.0074 (0.032) 0.0026 (0.034) Female 0.087 (0.14) 0.11 (0.15) 0.097 (0.14) 0.12 (0.15) Secondary education 0.35∗ (0.17) 0.37∗ (0.19) 0.36∗ (0.17) 0.37∗ (0.19) Post-secondary education -0.32 (0.23) -0.29 (0.24) -0.32 (0.23) -0.29 (0.25) Income 0.025 (0.043) 0.028 (0.046) 0.024 (0.043) 0.027 (0.046) Rural 0.25 (0.13) 0.13 (0.14) 0.26 (0.13) 0.14 (0.14) 10 1419 10 1334 Sampling strata 10 10 10 Sample size 1419 1419 1334 Ln likelihood Hypothesis tests (F-statistics from Wald tests with weighted data): Perceived costs + Costs*Pattani = 0 Standard errors in parentheses. ∗ p < 0.05 0.019 0.0049 coefficient on perceived costs is unchanged and significant at the 95% confidence level.17 Model 3 includes three controls that capture respondent views of conflict in Bangkok. In 2010 nationwide decentralization was one of the political reforms being considered to resolve the crisis at the center. Respondents’ views on southern autonomy may have been informed by their support for national decentralization. I control for whether a respondent told the TAF that they favored decentralization throughout Thailand (Favors decentralization).18 Second, respondent attitudes toward policy in the south may primarily reflect their view of the military’s role in politics—recall that there was a coup in 2006. Military role too large indicates that a respondent told TAF that the military was too prominent in Thai politics. Finally, Satisfaction w national government is a ranking from one to four of how satisfied the respondent was with the Bangkok regime. The relationship between conflict costs and support for southern autonomy is more stark after controlling for Thailand-wide decentralization, the military’s role in politics, and satisfaction with the national government (Model 3). The coefficient on perceived costs increases by 10% and remains significant. Pattani Malays and conflict costs Was the relationship between perceived conflict costs and support for southern autonomy the same for Pattani Malays and other Thai citizens? In the TAF survey, all of the respondents in Yala, Narathiwat and Pattani were Pattani-speakers. The sole Pattani-speaker in the survey who was not in the three southernmost provinces lived in adjacent Songkhla, which has seen some insurgent activity. By virtue of both their ethnicity and their location, the Pattani Malay respondents had more stake in southern autonomy and a greater likelihood of personal exposure to conflict 17 This is the only result reported here and in subsequent tables that is overturned if survey weights are not used (see Table A.8). If Model 2 is reestimated without weighted data, the coefficient on perceived costs is 0.55 and has a p-value of 0.070 in a two-tailed test of the null hypothesis. 18 After an explanation of decentralization, respondents were asked “Which statement is closer to your point of view? (1) Better to decentralize to local government. Or (2) The central government having the authority for decision making, as at present, would be more effective and efficient.” 14 violence. As noted above, Pattani Malays were much more likely to rate the conflict as Thailand’s most important problem. The policy solution to conflict at issue here, southern autonomy, would directly change the relationship between in-theater respondents and the government but would have only secondary effects on respondents elsewhere. Given the profound implications, in-theater respondents’ opinions on autonomy should be relatively stable compared to respondents in other provinces. Small changes in the perceived costs of the southern conflict could shift the views of Thais elsewhere, who do not attach much intrinsic importance to southern autonomy. By contrast, Pattani Malays are likely to hold strong views on the merits of autonomy. Therefore, only dramatic changess in the perceived severity of southern conflict would outweigh preferences regarding southern autonomy. Models 4 and 5 add an interaction between the Pattani Malay dummy variable and the perceived costs variable. Model 4 includes demographic control variables, Model 5 contains the full set of controls. The implications of these models are best captured in Figure 2. The figure plots the predicted difference in the probability that a respondent supported southern autonomy in case s/he believed conflict there was Thailand’s greatest problem. The predicted differences are plotted with 95% confidence intervals and displayed separately for non-Pattani and Pattani respondents.19 For non-Pattani respondents, predicted support for southern autonomy is 10–20% higher among those who perceived the costs of conflict as high. By contrast, among Pattanis, there is essentially no difference in support for autonomy between those who rated the conflict as Thailand’s major problem and others. The predicted change is small in magnitude and switches signs between Models 4 and 5, consistent with a null relationship. At the bottom of Table 1, I report Wald tests of the hypothesis that among Pattani Malays the combined coefficient on perceived costs equals zero. The tiny numbers reported there are actually F-statistics and not p-values. It is impossible to reject the hypothesis of a null effect in either Model 4 (p =0.89) or Model 5 (p =0.94). On the other hand, the wide confidence intervals on the Pattani/costs interaction term also means that the 19 Control variables are set to the mean value for continuous measures and modal value for indicator variables. 15 Difference in support for autonomy if perceived costs of southern conflict high Figure 2: Predicted difference in the probability of support for southern autonomy if respondent perceived high costs to the southern conflict, plotted for non-Pattani and Pattani respondents, with 95% confidence intervals .3 .2 .1 0 −.1 −.2 Model 4 Model 5 Respondent was: Non−Pattani Pattani Predicted changes in probability plotted with 95% confidence intervals predicted effect of perceived conflict severity among Pattani Malays overlaps the predicted effect on other respondents. Even with this uncertainty, the results in Models 4 and 5 reveal that the relationship between perceived costs and support for autonomy in earlier models is being produced by out-of-theater, non-Pattani respondents. Summary of main results Thai-speaking respondents, all of whom lived out-of-theater, display a war-weariness pattern familiar from studies of overseas wars. Those who thought the southern insurgency was a major problem wanted the government to compromise on autonomy. People who rated the costs of conflict lower were more content for the government to stay the course. Among Pattani Malays in- 16 theater, ratings of the conflict’s severity do not predict support for autonomy as a peacebuilding measure. With a large personal stake in the ultimate outcome of the conflict, Pattani Malay support for autonomy is similar regardless of how respondents rated the costs of conflict. This result does not rule out major effects of war costs on Pattani Malays in other respects such as interethnic trust. Also, an important limitation of the study here is that ethnic identity and geographic proximity to conflict are perfectly correlated in the survey sample. These factors need to be disentwined in future work. Nonetheless, the results suggest that in civil conflicts that are spatially isolated and involve issues of limited scope, there is an important distinction in how to understand public opinion among in- versus out-of-theater populations. That insight has not emerged from previous studies that have tended to focus on wars for control of the central government and wars in which the theater of violence encompassed most of the country. Yet, the majority of domestic counterinsurgency takes place in conflicts that, like the war in Thailand, are comparatively isolated both in terms of geography and the issues at stake. The remainder of this essay tests the robustness of the war-weariness model as an explanation for support for southern autonomy. The next section compares respondents’ perceptions of the cost of southern conflict to their support for compromise between competing factions in Bangkok. The aim is to conduct a placebo test. If the costs-of-southern-war variable predicts support for conciliatory policies in a different conflict, the costs variable may be measuring a general propensity for compromise. The final section of the paper looks for evidence that objective measures of military costs in the south are correlated with greater support for southern autonomy among out-of-theater respondents. 17 A placebo test: Political reconciliation in Bangkok One means to judge the credibility of the results in Table 1 is to compare perceptions of the costs of the southern conflict to survey questions about policies not directly related to those costs. In this section, I compare perceptions of the costs of southern conflict to respondent support for conciliatory policies toward clashing factions at the capital. It is possible that some people see all conflict as very high cost and have a strong preference for conciliation or compromise. In that case, there might be a strong positive relationship between perceived costs of conflict in the south and support for compromise in the national arena.20 On the other hand, the absence of a positive correlation would imply that the connection between the perceived costs of southern conflict and support for autonomy reflects opinions specific to events in the south. For this placebo test, I use questions about the competing “colored shirt” protest movements in Bangkok, which dealt with control of the central government. To review, in 2001 and 2005, Thaksin Shinawatra’s party won large victories in national elections. In 2006, Thaksin was overthrown in a military coup and went into exile. His allies won new elections in 2007 but their government was destabilized by opposition “yellow shirt” demonstrations in Bangkok. When the anti-Thaksin Democrat Party took power in 2008, the pro-Thaksin response was a corresponding campaign of “red shirt” demonstrations. Red shirts characterized Thaksin opponents as antidemocratic for supporting military and judicial coups. Yellow shirts argued Thaksin was the real threat to democracy, pointing to his weakening of oversight agencies and the free press and crediting his electoral success to corruption and vote buying. In its 2010 survey, TAF asked respondents whether charges of terrorism against red shirt protest leaders “should be dropped to promote political reconciliation” and posed the same question regarding yellow shirt protest leaders. I coded a dummy called Support central political reconciliation that takes a value of one if the respondent supported dropping the charges against both yellow 20 Or resolving conflict at the capital might be seen as a necessary step to resolving conflict in the south. 18 and red shirt leaders. Respondents who supported maintaining the charges against either or both sets of leaders are scored as a zero. About 60% of respondents supported dropping charges against both red and yellow shirt protest leaders; Pattani Malays and non-Pattani Malays were equally likely to support this form of political reconciliation. Table 2 reports logistic regressions of the perceived costs of the southern conflict and support for central political reconciliation. The bivariate regression (Model 6) shows a negative and statistically insignificant correlation between these measures. Adding control variables (Models 7 and 8), the coefficient on southern conflict severity remains negative but becomes statistically significant. The negative correlations here suggest that the results above—i.e., the positive correlation between perceived severity of southern conflict and support for autonomy (Table 1)—are not driven by a general taste for conciliatory policies. However, the presence of a statistically significant rather than a null relationship in Models 7 and 8 is unexpected.21 The results in this section refute the hypothesis that the relationship between perceived costs of southern conflict and support for southern autonomy reflects a general preference for compromise in the face of violence. The next section investigates the plausibility of a war-weariness effect in Thailand by asking a different question. Is there evidence that differential exposure to the “objective” costs of the southern conflict translates into support for southern autonomy? To gauge the answer, I take advantage of the geography of the Royal Thai Army (RTA). 21 A possible interpretation of this result is that it is an artifact of the wording of my question for gauging perceived costs of the southern conflict. Recall that the question asked for the biggest problem facing Thailand. Respondents whose response was the southern conflict implicitly revealed that they considered central conflict secondary. These respondents might also have seen little need for reconciliation in Bangkok. A test of this interpretation is to check whether my alternative measure of perceived costs (described above) relates to support for central reconciliation; this measure is based on a survey item asking respondents to list Thailand’s problems rather than asking them to rank those problems. In Table A.12, the alternative measure of perceived costs does not have a large or statistically significant correlation with support for central political reconciliation. The sign on the correlation is also unstable. These null results suggest the negative correlations in Table 2 are due to the limitations of my main measure of perceived costs. 19 Table 2: Logistic regressions of perceived costs of the southern conflict and respondent support for dropping charges against leaders of Bangkok protests Model 6 Model 7 Model 8 -0.63 (0.33) -0.84∗ (0.33) -0.82∗ (0.33) 0.50 (0.31) 0.53 (0.33) High perceived conflict costs Pattani Malay Favors decentralization -0.096 (0.15) Military role too large 0.55∗ (0.16) Satisfaction w national government -0.31∗ (0.10) Age -0.029 (0.031) -0.045 (0.032) Female -0.0047 (0.13) 0.037 (0.14) Secondary education -0.26 (0.17) -0.28 (0.18) Post-secondary education -0.57∗ (0.23) -0.62∗ (0.25) Income -0.088 (0.045) -0.11∗ (0.047) Rural 0.27∗ (0.13) 0.28∗ (0.14) 10 1419 10 1334 Sampling strata Sample size Standard errors in parentheses. 10 1419 ∗ p < 0.05 Military fatalities and support for southern autonomy Studies of casualty fatigue frequently compare the number of deaths from a respondent’s geographic jurisdiction to support for war. US public opinion has been compared to state and countrylevel fatalities, for example. The theory is that “in assessing these [war] costs, a respondent cannot help but weight proximate experiences more heavily, if for no other reason than this information is both salient and readily accessible” via both media channels and informal information networks within communities (Gartner et al., 1997, 674). Unfortunately, I do not have access to information on the home provinces of soldiers killed in southern Thailand. However, I can take advantage of the geographies of recruitment by Thailand’s four regional armies. Each of the four armies draws its membership primarily from a particular census region of Thailand. Also, in October, 2007, each army was assigned to a different southern district. Thus, for each respondent, I know which army’s region they live in. I can also observe military casualties in the southern district where that army was posted between October 2007 and the TAF survey. By 2010, about 30,000 soldiers had been deployed to the south, including the regular army and about 10,000 paramilitary rangers (ICG, 2010, 3).22 Units are rotated out of the south on an annual basis, so the share of soldiers with past, current, or future exposure to the southern conflict is even higher than these figures imply. The RTA deployments include both volunteers and conscripts. In Thailand, males ages 21 to 30 are required to participate in the annual draft lottery for two year terms in the army. Gonwong et al. (2014) explain the scope: The RTA uses a lottery system to select ≈ 60, 000 young Thai men at the district level of their family residence for enlistment annually. The men enlisted comprise approximately 10% of young men at the district level in Thailand (1531). 22 McCargo (2008, 102) estimates that 60% of soldiers in the south were RTA conscripts circa 2008. Rangers are often ex-conscripts who have finished their tour of duty. Other branches of the military played minimal roles in the south. 21 Volunteering for the army can result in a shorter stint. Students may delay the draft for up to five years. Relatively affluent Thais are frequently able to avoid the draft through education or corruption. Based in part on the census region where they lived (see Figure 1), recruits and conscripts are enrolled in one of the four commands of the RTA. The first army draws from the central region, the second from the northeast, the third from the north, and the fourth from the south, including the Pattani-majority provinces (Pimonpan, 2009). The correlation between recruits’ area of origin and the regional army they join is not perfect but available data indicates it is very high, especially for conscripts.23 Also, there is minimal migration between census regions in Thailand (ICG, 2010), reinforcing the regional character of each army.24 The geography of deployment, 2007–2010 A 2007 redeployment of the four armies in the south makes it possible to match military fatalities in the southern conflict to a regional army (see Table 3).25 Initially, the 4th army took the lead in southern counterinsurgency. In 2007, General Anupong took over command of southern military operations and reassigned the four RTA commands. The first army was put in charge of Narathiwat, the second in Pattani, and the third in Yala. The fourth army was given responsibility for five districts in Songkhla province, marginalizing that command in future counterinsurgency, “a mark 23 McQueen et al. (1996) reported that 100% of the conscripts at the 3rd Army base in Phitsanuloke at the time of their study were from the northern region. However, in a study of the 1st Army’s conscripts, Hatairat (2010) reported that the central region was overrepresented but so was the northeastern region (22–23). 24 A 2008 government survey found less than 3% of Thais live outside the census region where they were born (National Statistical Office, 2009, Table 1). 25 Military fatalities data are from the Global Terrorism Database (GTD), which is based on internationally-available news sources (National Consortium for the Study of Terrorism and Responses to Terrorism, 2013). The GTD categorizes government fatalities in terms of military, police, and civilian government officials. Reports from Deep South Watch, an NGO in southern Thailand, imply GTD understates the scope of the conflict. For example, the Deep South Watch data record 3,471 total deaths between January 2004 and May 2009 (Srisompob, 2009). In the same period, GTD records 844 deaths. Given the GTD’s sources, it is probably undercounting fatalities. However, missed fatalities are unlikely to be military personnel. 22 Table 3: Military fatalities and deployment of the Royal Thai Army by southern province Province Narathiwat Pattani Songkhla Yala Military fatalities, 1/04–9/07 RTA deployment after 10/07 Military Fatalities, 10/07–9/10† 16 9 0 4 1st (Central) 2nd (Northeast) 4th (South) 3rd (North) 26 8 0 1 †TAF survey fielded in September, 2010. of Anupong’s displeasure at its ineffectiveness in tackling the violence” (ICG, 2008, 6).26 As Table 3 shows, the number of military fatalities is southern Thailand between 2007 and 2010 was, by some standards, modest. The objective risk to a non-southern respondent or the repondent’s family was minimal. However, studies of overseas war suggest that small numbers of casualties can have dramatic impacts on public opinion. For example, Thai military fatalities per capita in the south from 2007–2010 were an order of magnitude larger than US deaths per capita during the 1993 Battle of Mogadishu (a.k.a., “Black Hawk Down”), which inspired a debate on public casualty aversion. With these pieces of information, I can ask whether the number of military fatalities associated with a respondent’s regional army is correlated with support for southern autonomy. However, a difficulty in comparing respondents across regional army areas is that there are also profound regional divides in Thai politics. To address this problem, I focus on six provinces located near the intersection of the 1st, 2nd, and 3rd army regions (Figure 3).27 The six provinces lie in three different army regions but are otherwise similarly situated. Importantly, the census/army regions have no additional administrative role.28 Other national ministries use alternative regional defini26 At the same time, Anupong announced a plan to recruit a new infantry division that would be drawn heavily from the three southernmost provinces. However, progress on recruiting and deploying that division was slow. At the end of 2010, soldiers in the south were overwhelmingly from elsewhere in Thailand (ICG, 2010, fn. 12). 27 None of the TAF survey provinces were close to the border between the central and southern regions (Figure A.1). 28 Lop Buri and Nakhon Ratchasima are potential outliers because they have important RTA bases; these provinces can be dropped without overturning the results below (Table A.16). 23 tions. Local government bodies are at the provincial level or below. The army regions are also not equivalent to political jurisdictions. In the 2007 elections (the last before the TAF survey), parliament was selected through (1) single member districts (SMD) nested within provinces and (2) seats rewarded proportionally based on election zones comprised of several provinces.29 The six provinces in Figure 3 spanned three different election zones in 2007 elections. Provinces that shared an army region did not necessarily share an election zone and vice versa. The table accompanying Figure 3 also shows that in all six provinces the 2007 single-member races were mostly won by the pro-Thaksin party—the PPP—or by one of the parties that joined the PPP government after the elections. In other words, the core party of opposition to Thaksin, the Democrat Party, was weak in all of these provinces. A further objection to using fatalities from a respondent’s regional army command to predict views on southern autonomy is that RTA assignments in 2007 may have been based on public opinion. Perhaps armies from parts of the country relatively sympathetic to southern grievances were sent to more dangerous districts in an effort to win hearts and minds. If so, there might be a spurious positive relationship between more military fatalities and more support for southern autonomy. However, the 2007 assignment strategy seems to have accomplished the opposite. The 1st army, from central Thailand, was assigned to Narathiwat, the province that incurred the most military casualties both before and after the 2007 redeployment (Table 3). Central Thailand, compared to north and northeast Thailand, was more friendly to the military and the Democrat Party. A reasonable expectation would be that the public in this region was less inclined to contradict the sitting Democrat central government’s policy, ceterus paribus. Also, according to the TAF survey data, decentralization for any part of Thailand was less popular in the central zone (roughly 60% of respondents supporting) than in the north (72%) and northeast (70%). 29 Election data from Carr (2016). 24 Figure 3: Survey districts on northern, northeastern, and central army region borders N Khon Kaen NE Petchabun Nakhon Ratchasima Lop Buri Sing Buri C Prachin Buri Province Petchabun Khon Kaen Nakhon Ratchasima Lop Buri Prachin Buri Sing Buri Army region Election zone, 2007 Province SMD seats won by PPP, 2007 Province SMD seats in PPP coalition, 2007 3rd (N) 2nd (NE) 2nd (NE) 1st (C) 1st (C) 1st (C) 2 2 5 2 5 7 4 of 6 (66%) 11 of 11 (100%) 6 of 16 (38%) 3 of 5 (60%) 2 of 3 (66%) 0 of 1 (0%) 5 of 6 (83%) 11 of 11 (100%) 16 of 16 (75%) 4 of 5 (80%) 3 of 3 (100%) 1 of 1 (100%) Regional army fatalities and support for southern autonomy Table 4 reports logistic regressions comparing military fatalities in a respondent’s army region to support for southern autonomy.30 Model 9 is the bivariate regression of logged military fatalities and endorsement of southern autonomy. Military fatalities are positively signed and statistically significant. The substantive interpretation of this result appears in Figure 4. Predicted support for southern autonomy is plotted against unlogged military fatalities ranging from one to 26, the span of the data. The predicted level of support quadruples over this range: from 20% in case of one military fatality to 80% at the maximum. The coefficient on logged fatalities remains statistically significant and similar in magnitude as basic demographic control variables are added (Model 10). Note that there were no Pattani Malay respondents in these six provinces; that control variable is omitted. The positive relationship between army region fatalities and support for southern autonomy also persists after controlling for attitudes about countrywide decentralization, the military, and the sitting government (Model 11). Finally, I repeat the placebo test performed above, comparing the fatalities from a respondent’s army area to support for dropping charges against Bangkok protest leaders. The correlations reported in Models 12–14 (Table 4) are not statistically distiguishable from null effects and change signs between models. Again, this non-result implies that southern conflict costs are specifically relevant to understanding attitudes about southern autonomy. In sum, respondents living at the border of three recruitment regions for the RTA were more likely to support southern autonomy if their region’s army was posted in a deadlier part of the south. These results need to be interpreted conservatively because the military casualty data is very aggregated and may proxy for differences in regional politics, despite the steps taken to address that problem. On the other hand, these results can be combined with the earlier analysis in which 30 Unweighted results are reported in Table A.13. Table A.14 reestimates the models in Table 4 without survey weights but with standard errors clustered by province. 26 Table 4: Logistic regressions of respondent support for southern autonomy and for dropping charges against central protestors compared to military fatalities in southern conflict associated with the respondent’s army region Southern autonomy Central political reconciliation Model 9 Model 10 Model 11 Model 12 Model 13 Model 14 0.84∗ (0.17) 0.85∗ (0.18) 0.82∗ (0.20) -0.064 (0.14) -0.031 (0.14) 0.039 (0.16) Ln regional army fatalities Favors decentralization 1.6∗ (0.32) -0.62∗ (0.31) Military role too large -0.47 (0.35) 0.45 (0.31) Satisfaction w national government -0.26 (0.28) -0.14 (0.23) Age -0.032 (0.074) -0.038 (0.075) 0.087 (0.066) 0.054 (0.066) Female 0.14 (0.30) 0.030 (0.33) -0.41 (0.27) -0.34 (0.28) Secondary education -0.13 (0.40) -0.38 (0.42) -0.21 (0.34) -0.18 (0.36) Post-secondary education -1.2∗ (0.57) -1.5∗ (0.64) -0.080 (0.52) 0.048 (0.54) Income 0.13 (0.092) 0.12 (0.092) -0.098 (0.092) -0.13 (0.093) Rural -0.15 (0.26) -0.11 (0.29) 0.30 (0.26) 0.28 (0.27) 6 317 6 299 6 317 6 299 Sampling strata Sample size Standard errors in parentheses. 6 317 ∗ p < 0.05 6 317 Predicted probability of support for southern autonomy Figure 4: Predicted probability of support for southern autonomy and military fatalities from a respondent’s army region.

Taken together, the evidence is consistent with conflict costs eroding public support for a purely coercive response to southern insurgency. Conclusion In 2010, the Thai public was asked about the desirability of using regional autonomy to end conflict in the south of that country. My analysis of this polling data concerns how war costs influenced the respondents’ view of southern autonomy. Perceived severity of the southern conflict predicts greater support for southern autonomy but not for reconciliatory policies in central conflict. Respondents living in regions associated with more military casualties in the south were also more likely to endorse southern autonomy. These findings suggest a casualty fatigue model of public opinion similar to that reported in studies of overseas war rather than the hardening of antagonisms stressed in much of the civil war literature. A relationship between perceived war costs and willingness to support policy compromises does not rule out other forms of polarization, such as increasing social intolerance. However, in this case, any such animosities did not translate directly into increased public appetite for war or unwillingness to compromise in order to end war. It is also notable that the casualty fatigue finding is limited to survey respondents who lived out-of-theater. The in- and out-of-theater distinction in the data is likely to be important in most civil conflicts, which involve geographically isolated fighting and policy demands that have limited direct implications for many citizens. Earlier studies of public opinion and civil war have considered cases that are not representative in these respects. This study takes a first step toward broadening our base of knowledge about public opinion and domestic war. The next step for future research will be to further specify contexts in which war costs increase public support for compromising with insurgents’ aims. If a casualty fatigue model is borne out in other data, that finding would raise a number of questions about how public 29 opinion shapes domestic counterinsurgency, for example whether anticipation of an adverse public reaction to war costs influences central military tactics or prompts political compromise. 30 References Abuza, Zachary. 2011.

Do you agree or disagree?” • Support central political reconciliation (0/1): Respondents answered two items related to charges against the main political factions in protests at the capital: “And for the leader of red shirts [who] has been accused for terrorism, do you think the lawsuit and charges should be dropped to promote the political reconciliation?” and “And for the leader of yellow shirts [who] has been accused for terrorism, do you think the lawsuit and charges should be dropped to promote the political reconciliation?” Respondents who supported dropping charges against both yellow and red shirt leaders were coded as supporting central reconciliation. Respondents who said the charges should stand against the yellow shirt leaders, the red shirt leaders, or both sets of leaders were coded as a zero. • High perceived conflict costs (0/1): Respondents were asked “In your view, what is the biggest problem facing Thailand?” I code high perceived costs for respondents who described conflict in southern Thailand as the country’s biggest problem. • High perceived conflict costs II (0/1): Respondents were also asked “Generally speaking, do you think things in Thailand today are going in the right direction, or do you think they are going in the wrong direction?” and an open-ended follow-up question “Why do you say that?” Enumerators listed up to six answers to the open-ended follow-up question. I coded High perceived conflict costs II as a 1 if a respondent who thought Thailand was going in the wrong direction listed conflict in the south as one of the reasons for that opinion. This variable is coded as a zero if the respondent did not include the southern conflict in their list of reasons for pessimism. This variable is coded only for the 866 (61%) of respondents who thought Thailand was going in the wrong direction. • Pattani Malay (0/1): “Normally, what language do you speak at home?” Respondents who reported that they spoke Pattani Malay or Yawa are coded as Pattani Malay. • Favors decentralization (0/1): “Sometimes people in Bangkok and upcountries have different interests and different points of view; therefore, some people say that the government could work more effectively and efficiently if the power of decision making were decentralized to local governments. In addition, the governor should be directly elected (like in Bangkok). However, some people believe that the government will be more fair, more effective and more efficient if centrally controlled. Which statement is closer to your point of view? (1) Better to decentralize to local government. Or (2) The central government having the authority for decision making, as at present, would be more effective and efficient.” If the respondent was uncertain of the meaning of decentralization, the following text was also read: “Decentralization means to decentralize power to local areas under democratic 3 governance. It’s aimed to reduce central government’s role so that they can focus on key missions as necessary as possible [sic] and to enhance the role of local government to take over duties. The law is required to allow local government to have authority in managing works, money, and labor to solve its problems and to develop its own areas; it means some local laws can follow local interests, custom and tradition. This is based on the fundamental in which local people best know their own local problems and interests. The familiar forms of local government are Sub-District Administration Office (SAO), municipal, Provincial Administration Office (PAO), and such special districts as Bangkok and Pattaya.” Respondents who said it was “better to decentralize to local government” (choice 1) were coded as favoring decentralization. • Military role too large (0/1): “Many people think the army plays too big a role in politics in Thailand, while others see the army as an important independent institution that has helped safeguard and stabilize the country. Which is closer to your view?” • Satisfaction with national government (1–4): “How do you feel regarding the job the national government is doing?” Very dissatisfied (1); Somewhat dissatisfied (2); Somewhat satisfied (3); Very satisfied (4). • Age (2–11): “May I know your age please?” Less than 18 (survey terminated); 18–19 years old (2); 20–24 years old (3); 25–29 years old (4); 30–34 years old (5); 35–39 years old (6); 40–44 years old (7); 45–49 years old (8); 50–59 years old (9); 60–80 years old (10); Above 80 years old (11). • Female (0/1): Coded by enumerator. • Secondary education (0/1): Based on responses to the item “Could you please tell me your highest education?” Respondents who chose “Secondary school” or “Diploma/Vocational” school were coded as a 1. Respondents who chose “Primary school or below,” “Bachelors degree,” “Masters degree,” or “Doctoral degree” were coded as a zero. • Post-secondary education (0/1): Based on responses to the item “Could you please tell me your highest education?” Respondents who chose “Bachelors degree,” “Masters degree,” or “Doctoral degree” were coded as a 1. Respondents who chose “Primary school or below,” “Secondary school,” or “Diploma/Vocational” school were coded as a zero. • Income (1–9): Respondents were asked “Could you please tell me your monthly household income which mean[s] the income of all household members (including all sources of income)?” TAF recorded household income in three separate income scales: one for Bangkok, another for other urban respondents, and a third for rural respondents. My variable notes each respondents’ score on their local scale; thus, this is an income measure relative to the respondent’s locality, which may help to capture differences in purchasing power. 4 Income in 1000s of Baht† Coding Bangkok Other urban Rural 1 2 3 4 5 6 7 8 9 <15 15–24.9 25–49.9 50–59.9 60–69.9 70–79.9 80–89.9 90–99.9 ≥100 <8 8–14.9 15–34.9 35–44.9 45–49.9 5–59.9 60–69.9 70–79.9 ≥80 <5 5–7.9 8–19.9 20–22.49 22.5–29.9 30–39.9 40–49.9 50–59.9 ≥60 †In mid-2010, 1000 Baht was worth about $31 US • Rural (0/1): Respondents lived in either a rural or an urban district of a province.
