Abstract
Using data from the AfroBarometer survey, this chapter derives measures of overall well-being for six Eastern African countries (Burundi, Madagascar, Kenya, Tanzania, Malawi, and Mozambique) for which enough data were available to take a broad enough view of well-being. Correspondence analysis is implemented to aggregate variables in each domain of well-being while overall well-being is derived through efficiency analysis. The chapter compares the findings concerning overall well-being with those based on its narrow view, one whose focus is only on material well-being. It appears that the two main determinants of material well-being are the educational level of the individual and his/her area of residence. For the measure of overall well-being the findings were less clear-cut.

Notes
- 1.
The choice of countries and of variables was in part dictated by the availability of data.
- 2.
See Appendix 2 for more details on this technique.
- 3.
Note that our dependent variable varies between zero and one and could not be conveniently transformed into logs. However, the distribution of the dependent variable fits a normal shape and the prerequisites for OLS estimations. This also simplifies the interpretation of the coefficients.
- 4.
The present paper is on the measurement of well-being and does not deal with identities and their relation to cultural and political pretensions or histories of conflict.
- 5.
It should be stressed that in some countries like Madagascar the name of some ethnic groups is related to the ecological conditions of the territory that they occupy. The present paper does not intend to delve into the political economy of ethnicity and ethnic control over resources.
- 6.
For an illustration of the use of PCA, see, for example, Berrebi and Silber (1981).
- 7.
Very similar results can be derived for the other factorial axes.
- 8.
This is also the case of other indices that are usually used to approximate the Malmquist index such as the Paasche index, the Laspeyres index or the Fisher index.

Appendix 2: On Correspondence Analysis
Correspondence analysis (CA) was originally introduced by Benzécri and Benzécri (1980). It is strongly related to the principal components analysis (PCA) but while PCA assumes that the variables are quantitative, CA has been designed to deal with categorical variables. More precisely, CA offers a multidimensional representation of the association between the row and column categories of a two-way contingency table. In short CA’s goal is to find scores for both the row and column categories on a small number of dimensions (axes) that will account for the greatest proportion of the chi2 measuring the association between the row and column categories. There is thus a clear parallelism between CA and PCA, the main difference being that PCAFootnote 6 accounts for the maximum variance. A clear presentation of CA is given in Asselin and Vu Tuan Anh (2008: Chap. 5) and in Kakwani and Silber (2008).
Let us first recall the main features of PCA. It is a data reduction technique that consists of building a sequence of orthogonal and normalized linear combinations of the K primary indicators that will exhaust the variability of the set primary indicators. These orthogonal linear combinations are evidently latent variables and are usually called as ‘components’. In PCA the first component has the greatest variance and all subsequent components have decreasing variances.
Let N be the size of the population, K the number of indicators \( I_{k} \). The first component \( F^{1} \) may be expressed for observation i as:
Where \( I^{*k} \) refers to the standardized primary indicator \( I^{k} \). Note that \( \omega_{k}^{1} \) is the (first) factor score coefficient for indicator k. It turns out that the scores \( \omega_{k}^{1} \) are in fact the multiple regression coefficients between the component \( F^{1} \) and the standardized primary indicators \( I^{*k} \). It is important to understand that PCA has some limitations, of which the most important is probably the fact it has been developed for quantitative variables.
It is therefore better not to use PCA when some of the variables are of a qualitative nature. (Multiple) Correspondence Analysis (MCA) is in fact a data reduction technique that should be used in the presence of categorical variables.
Let us therefore assume now that the K primary indicators are categorical ordinal and that the indicator \( I^{k} \) has \( J^{k} \) categories. Note that if some of the variables of interest are quantitative, it is always possible to transform them into a finite number of categories. To each primary indicator \( I^{k} \) we therefore associate the set of \( J^{k} \) binary variables that can only take the value 0 or 1.
Let us now call \( X(N,J) \) the matrix corresponding to N observations on the K indicators which are now decomposed into \( J^{k} \) variables. Note that \( J = \sum\nolimits_{k = 1}^{K} {J^{k} } \) represents now the total number of categories. Call \( N_{j} \) the absolute frequency of category j. Clearly \( N_{j} \) is equal to the sum of column j of the matrix X. Let \( N_{..} \) refer to the sum of all the \( (N\,by\,K) \) elements of the matrix X. Let also \( f_{j} \) be the relative frequency \( (N_{j} /N_{..} ) \), \( f^{i} \) be the sum of the ith line of matrix X, \( f_{ij} \) be the value of cell (i, j), and \( f_{j}^{i} \) be equal to the ratio \( (f_{ij} /f^{i} ) \). Finally, call \( \{ f_{j}^{i} \} \) the set of all \( f_{j}^{i} \)’s for a given observation i (j = 1 to J). This set will be called the profile of observation i.
As stressed previously CA is a PCA process applied to the matrix X, but with the \( \chi^{2} \)-metric on row/column profiles, instead of the usual Euclidean metric. This \( \chi^{2} \)-metric is in fact a special case of the Mahalanobis distance developed in the 1930s. This metric defines the distance \( d^{2} \left( {f_{j}^{i} ,f_{j}^{{i^{\prime}}} } \right) \) between two profiles i and i′ as:
Note that the only difference with the Euclidean metric lies in the term \( (1/f_{j} ) \). This term indicates that categories which have a low frequency will receive a higher weight in the computation of distance. As a consequence CA will be overweighting the smaller categories within each primary indicator. It can be shown that:
where \( \omega_{j}^{1,k} \) is the score of category \( j_{k} \) on the first (non-normalized) factorial axis, \( I_{j}^{k} \) is a binary variable taking the value 1 when the population unit belongs to the category \( j_{k} \), \( F^{1*} \) is the normalized score on the first axis, and \( N_{j}^{k} \) is the frequency of the category \( j_{k} \) of indicator k.
It is also interesting to note that CA offers a unique duality property since it can be shown that:
where K is the number of categorical indicators, \( J_{k} \) is the number of categories for indicator k, \( w_{j}^{1,k} \) is the score of category \( j_{k} \) on the first (non-normalized) factorial axis, \( I_{i,j}^{k} \) is a binary variable taking the value 1 when unit i belongs to category \( j_{k} \), and \( F_{1}^{i} \) is the (non-normalized) score of observation i on the first factorial axis.Footnote 7
Reciprocally it can be shown that:
This duality relationship implies that the score of a population unit on the first factor is equal to the average of the standardized factorial weights of the K categories to which it belongs. Conversely the weight of a given category is equal to the average of the standardized scores of the population units belonging to the corresponding category.

Duality and the Concept of Input Distance Function in Production Theory:
Let \( x_{i} = (x_{1i} , \ldots ,x_{ji} , \ldots ,x_{ki} ) \) denote the vector of levels of social exclusion in the various k domains of social exclusion for individual i and let \( y_{i} \) denote the overall level of social exclusion for individual i. An individual’s performance, as far as social exclusion is concerned, may hence be represented by the pair \( (x_{i} ,y_{i} ) \), i = 1, …, I.
A theoretical social exclusion index SE can then be estimated using a Malmquist input quantity index:
where x s and x t are two different ‘social exclusion inputs’ vectors and \( D_{\text{input}} \) is an input distance function. The idea behind the Malmquist index is to provide a reference set against which to judge the relative magnitudes of the two vectors of ‘social exclusion inputs’. That reference set is the isoquant \( L(y) \) and the radially farther \( x_{i} \) is from \( L(y) \), the higher the overall level of social exclusion of individual i is, for \( x_{i} \) must be shrunk more to move back onto the reference set \( L(y). \)
There is, however, a difficulty because the Malmquist index depends generally on y. One could use an approximation of this index such as the Tornquist index, but such an index requires price vectors as well as behavioral assumptions.Footnote 8 Since we do not have prices for ‘social exclusion inputs,’ we have to adopt an alternative strategy. The idea is to get rid of y by treating all individuals equally and assume that each individual has the same overall level of social exclusion: one unit for each ‘social exclusion input’. Let e represent such a vector of ‘social exclusion inputs’—a k-dimensional vector of ones. Thus, the reference set becomes L(e) and bounds the vectors of ‘social exclusion inputs’ from below. Individuals with ‘social exclusion vectors’ on to L(e) share in fact the lowest level of ‘overall social exclusion’, with an index value of unity, whereas individuals with large vectors of ‘social exclusion inputs’ will then have higher overall levels of social exclusions, with index values above unity.
To estimate the distance function, let \( \lambda = (1/x_{k} ) \) define a \( (k - 1) \) dimensional vector \( z \) as \( z = \{ z_{j} \} = (x_{j} /x_{k} ) \) with \( j = 1, \ldots ,k - 1 \). Then \( D_{\text{input}} (z,e) = (1/x_{k} )D_{\text{input}} (x,e) \) and, since \( D_{\text{input}} (x,e) \ge 1, \), we have:
This implies that we may also write it as:
By assuming that \( D_{\text{input}} (z,e) \) has a translog functional form, we have:
Estimates of the coefficients \( \alpha_{j} \) and \( \alpha_{jh} \) may be obtained using corrected ordinary least squares (COLS) or maximum likelihood methods (see later) while the input distance function \( D_{\text{input}} (z_{i} ,e) \) for each individual i is provided by the transformation
This distance will, by definition, be greater than or equal to one (since its logarithm will be positive) and will hence indicate by how much an individual’s ‘social exclusion input vector’ must be scaled back in order to reach the ‘social exclusion inputs’ frontier. This procedure guarantees therefore that all ‘social exclusion input vectors’ lie on or above the resource frontier \( L(e). \) The overall level of social exclusion for individual i will then be obtained by dividing \( D_{\text{input}} (z_{i} ,e) \) by the minimum observed distance value—which by definition equals 1.

Estimation Procedures: The Stochastic Production Frontier Approach
Let us take as a simple illustration, the case of a Cobb–Douglas production function. Let \( \ln y_{i} \) be the logarithm of the output of a firm i \( (i = 1\,{\text{to}}\,N) \) and \( x_{i} \) a \( (k + 1) \) row vector, whose first element is equal to one and the others are the logarithms of the k inputs used by the firm. We may then write that:
where \( \beta \) is a \( (k + 1) \) column vector of parameters to be estimated and \( u_{i} \) a nonnegative random variable, representing technical inefficiency in production of firm \( i \).
The ratio of the observed output of firm i to its potential output will then give a measure of its technical efficiency \( {\text{TE}}_{i} \) so that:
One of the methods that allows the estimation of this output-oriented Farrell measure of technical efficiency TE i (see, Farrell 1957) is to use an algorithm proposed by Richmond (1974) which has become known as corrected ordinary least squares (COLS). This method starts by using ordinary least squares to derive the (unbiased) estimators of the slope parameters. Then in a second stage the (negatively biased) OLS estimator of the intercept parameter \( \beta_{0} \) is adjusted up by the value of the greatest negative residual so that the new residuals all become nonnegative. Naturally the mean of the observations does not lie any more on the estimated function; the latter has become in fact an upward bound to the observations.
One of the main criticisms of the COLS method is that it ignores the possible influence of measurement errors and other sources of noise. All the deviations from the frontier have been assumed to be a consequence of technical inefficiencies. Aigner et al. (1977) and Meeusen and van den Broeck (1977) have independently suggested an alternative approach called the stochastic production frontier method in which an additional random error \( v_{i} \) is added to the nonnegative random variable \( u_{i} \). We can therefore write:
The random error \( v_{i} \) is supposed to take into account factors such as the weather and luck and it is assumed that the \( v_{i} \)’s are i.i.d. normal random variables with mean zero and constant variance \( \sigma_{v}^{2} \). These \( v_{i} \)’s are also assumed to be independent of the \( u_{i} \)’s, the latter being taken generally to be i.i.d. exponential or half-normal random variables. For more details on this maximum likelihood estimation procedure, see Battese and Corra (1977) and Coelli et al. (1998), as well as programs such as FRONTIER (Coelli 1992) or LIMDEP (Green 1992). The same methods (COLS and maximum likelihood) may naturally also be applied when estimating distance functions.
