Abstract

This article examines how government policies affect ethnic relations by comparing outcomes across two nearby districts, one in Kenya and one in Tanzania, using colonial-era boundary placement as a “natural experiment.” Despite similar geography and historical legacies, governments in Kenya and Tanzania have followed radically different language, education, and local institutional policies, with Tanzania consistently pursuing more serious nation building. The evidence suggests that nation building has allowed diverse communities in rural Tanzania to achieve considerably better local public goods outcomes than diverse communities in Kenya. To illustrate, while Kenyan communities at mean levels of diversity have 25 percent less local school funding than homogeneous communities on average, the comparable figure in the Tanzanian district is near zero. The Kenya-Tanzania comparison provides empirical evidence that serious reforms can ameliorate social divisions and suggests that nation-building should take a place on policy agendas, especially in Africa.

43 Quantitative evidence from current schoolbooks also suggests that the Kenyan curriculum is considerably less Pan-Afncanist in orientation than the Tanzanian curriculum. As a rough measure of curricular emphasis, we counted the number of times the word “Africa” (or “African”) appears in nine current Kenyan and Tanzanian GHC textbooks for grades 3—6 and found more than twice as many instances in the Tanzanian textbooks (66.5 times per book) as in the Kenyan books (28.6).

56 Ethnic diversity (ELF) in the villages with missing data is nearly identical on average to diversity in villages that are included in the sample, and the small difference in ELF (0.16 to 0.13) is not statistically significantly different than zero at traditional confidence levels. Hence, even if the five villages with some missing data happened to be poor performers in terms of local collective action, the inclusion of these villages would be unlikely to substantially change the main empirical results.

68 An alternative explanation for the existence of a stronger national identity in Tanzania could be the successful 1979 war repelling a Ugandan invasion. Although victorious wars have long been credited with promoting national unity, this hypothesis appears unlikely here for at least two reasons: first, the Uganda war lasted only three months, and second, the war led to an exhausting six-year occupation of Uganda that nearly bankrupted the country and contributed to the financial crisis of 1982; see Gordon, D. F., “International Economic Relations, Regional Cooperation, and Foreign Policy,” in Barkan, Joel D., ed., Beyond Capitalism versus Socialism in Kenya and Tanzania (Boulder, Colo.: Lynne Rienner, 1994)Google Scholar.

69 Only six of eighty-four sample schools report having received over U.S.$100 in outside funding in the 1996 survey, and U.S.S100 is a low level for schools with three hundred to four hundred students on average. Similarly, a minority of projects in the Tanzanian district received any external central government or NGO assistance, and in many cases the amounts received were modest.

70 Unfortunately, there are no data on income (or consumption expenditures) for the Kenyan villages, so income cannot be included as a control variable in the main regressions.

73 These differences are somewhat misleading: the Kenyan data are for pupils' fathers, while, even though two-thirds of Tanzanian respondents were male and young adults—and thus comparable to the Kenyan respondents—some Tanzanian respondents were women or elderly. Women and the elderly have less education and formal employment than young men on average, and thus actual socioeconomic gaps between the two districts are likely to be somewhat smaller than those reported in Table 1.

74 Religious diversity is not included as an explanatory variable in the analysis since local religious affiliation is not plausibly exogenous due to extensive missionary activity in both districts. Correlations between religious fragmentation and local outcomes would be misleading if evangelical activity is most successful in the poorest areas or in areas with low levels of social capital. The numerical strength of “traditional” religions in Meatu—over 60 percent of the sample—also complicates the interpretation of the religious fragmentation index, since it is difficult to disentangle different traditional belief systems from ethnicity. Finally, since the most politically salient religious cleavage in East Africa is that between Christians and Muslims, the absence of large Muslim populations in these districts blunts the most likely source of religious divisions.

75 Miguel and Gugerty (fn. 6).

76 Ethnic diversity is unlikely to be proxying for higher local income inequality in Tanzanian villages, since the correlation between diversity and inequality is small, negative, and not statistically significant (regression not shown).

77 We attempted to examine analogous issues in the Kenyan district, but data on registered community group membership were only available for part of the study area. Restricting attention to registered community groups is also not ideal, since many groups are not registered in Kenya. The relationship between local diversity and registered group membership in this limited sample is typically negative (not shown), but due to the data limitations mentioned above, we do not highlight the Kenyan results.

79 The correlation between social capital and ethnic diversity is similar in a nationally representative sample of eighty-seven rural Tanzanian clusters, using data from the World Bank's 1995 Social Capital and Poverty Survey (SCPS) and 1993 Human Resource Development Survey (HRDS) (not shown).
