Abstract
The question of why some immunization programmes in sub-Saharan Africa are more successful than others is an intriguing one, but not one that is frequently raised or investigated. Borrowing techniques from both performance benchmarking and positive deviance inquiry, we explored this question in six countries. We first set out to define for a systematic sample of countries the key constructs commonly associated with improving immunization coverage, using an inductive, insider point of view. We then explored their utility in generating hypotheses about coverage differences across countries through a preliminary application of the measures of these constructs to the countries in this sample. Our findings suggest that there are different paths to success, and that not only what countries do, but how they execute their programmes, seem to make a difference in coverage outcomes. In some cases, extramural, contextual factors may also help to explain these differences. We discuss several hypotheses generated by our study, identify methodological limitations, and recommend improvements to the methods we used. Similar formative studies are needed to validate our preliminary hypotheses, to generate new ones, and to raise our level of confidence in the early policy implications that we see emerging from our preliminary work in this area. Eventually, testing of the hypotheses generated by this and other formative studies could generate a robust theory of why some programmes are more successful than others, a phenomenon likely to be relevant to other child and maternal health programmes in sub-Saharan Africa.

Publication Why Do Some Countries Default More Often Than Others? The Role of Institutions(2012-03-01)This paper examines how a country's weak institutions and polarized government can affect the likelihood of its default on sovereign debt. Using a data set of 90 countries, it shows that strong institutions are associated with fewer sovereign default crises. In addition, when institutions are weak, a more polarized government tends to default more often. To explain these findings, the author develops a model showing the dynamics between the quality of institutions, the level of government polarization and sovereign default risk. Countries default more often when they lack rules and strong institutions to curb the influence of powerful groups on government policies. That is because in a polarized government, each powerful group makes decisions without considering the impact on other groups. Simulations of the model show that more than half the cross-country variation in sovereign default frequencies can be explained by institutional quality and the degree of government polarization observed in the data.Publication Why Do Some Oil-Rich Countries Perform Better Than Others?(World Bank, Washington, DC, 2017-05)Progress in child mortality reduction and education attainment varies widely among oil-rich countries. This paper investigates the causes of this variation using an empirical model that departs from the available literature in allowing for explicit measurement of the impact of initial levels of child mortality and education attainment. The results show that the following four variables are statistically significant and robust across various specifications: public spending on health and education, economic growth rates, caloric sufficiency, and initial levels of child mortality and education attainment. Further analysis was conducted to determine the economic significance of these factors by examining the contribution of each to the fitted growth rates (as a deviation from the sample mean) of child mortality and secondary school enrollment for 14 oil-rich developing countries. The analysis reveals some interesting patterns. First, initial conditions dominate the results for education attainment: the initial level of secondary school enrollment in 1980 is the dominant factor in explaining subsequent improvements in 10 of the 14 oil-rich developing countries for which calculations could be performed. Second, policy factors worked in different ways in different countries. A high degree of caloric sufficiency enabled countries in the Middle East and North Africa to reduce child mortality faster, while low levels of caloric sufficiency prevented African oil-rich countries, such as Angola and the Republic of Congo, from making progress. Third, levels of public spending were not economically critical for gains in school enrollment, although they were important in a few country cases for improvements in child mortality rates.Publication Labor Market "Rigidity" and the Success of Economic Reforms across More than 100 Countries(World Bank, Washington, DC, 2001-01)The authors show that labor market policies and institutions affect the effectiveness of economic reform programs. They compare annual growth rates across 119 countries, using data from 449 World Bank adjustment credits and loans between 1980 and 1996. The results indicate that countries with relatively rigid labor markets experienced deeper recessions before adjustment and slower recoveries afterward. The results also disentangle the mechanisms through which labor market rigidity operates. They find that minimum wages and mandatory benefits do not hurt growth. But the relative size of organized labor (in government and elsewhere) appears to matter. Labor market rigidity seems to be relevant more for political reasons than for economic reasons. The authors' findings suggest that not enough attention has been paid to vocal groups (urban, middle-class groups) that stand to lose from economic reform. The implications of the findings for policymakers: There should be less focus on deregulating the labor market and more on defusing the opposition of (vocal) losers. The results are robust to changes in measurement, controls, and sample, and do not suffer from self-selection bias.Publication Job Growth and Finance : Are Some Financial Institutions Better Suited to the Early Stages of Development than Others?(Oxford University Press on behalf of the World Bank, 2013-09)Evidence based on firm-level data from 89 countries with updated country-level data on financial structure suggests that in low-income countries; labor growth is more rapid in countries with a higher level of private credit/GDP. This positive relationship with private credit is especially pronounced in industries that depend heavily on external finance. The results, which are robust to multiple estimation approaches, are consistent with the predictions of new structural economics. In high-income countries, labor growth rates increase with the level of stock market capitalization, consistent with predictions from new structural economics. However, the association disappears when stock market development is treated as an endogenous explanatory variable using instrumental variable regressions. There is no evidence that small-scale firms in low-income countries benefit the most from the development of the private credit market. Rather, the labor growth rates of larger firms increase to a greater extent than others with the level of private credit market development, a finding consistent with the perspective from historical political economy that banking systems in low-income countries serve the interests of the elite rather than providing broad-based access to financial services.Publication Job Growth and Finance : Are Some Financial Institutions Better Suited to Early Stages of Development Than Others?(2011-11-01)This paper combines firm-level data from 89 countries with updated country-level data on financial structure, and uses two estimation approaches. It finds that in low-income countries, labor growth is swifter in countries with a higher level of private credit/gross domestic product; the positive effect of bank credit is especially pronounced in industries that depend heavily on external finance; and banking development is positively associated with more physical and human capital investment. These findings are consistent with predictions from new structural economics. In high-income countries, labor growth rates are increasing in the level of stock market capitalization, which is also consistent with predictions from new structural economics, although the analysis is unable to provide evidence that the association is causal. It finds no evidence that small-scale firms in low-income countries benefit most from private credit market development. Rather, the labor growth rates of larger, capital-intensive firms increase more with the level of private credit market development, a finding consistent with the history-based political economy view that banking systems in low-income countries serve the interests of the elite, rather than providing broad-based access to financial services.
