What drive financial inclusion gender gap in Cameroon? A Fairlie decomposition approach METHODOLOGICAL APPROACH AND DATA 3.1 Methodology: To analyze the drivers of gender gaps in financial inclusion in Cameroon, we use a nonlinear Fairlie decomposition. The Fairlie decomposition is an extension of the Blinder–Oaxaca decomposition that overcomes the problems encountered in the Blinder (1973) and Oaxaca (1973) approaches, particularly the limitations posed when the dependent variable is a dichotomous, polytomous, censored, or truncated variable (Jann, 2008). The main advantage of applying this methodological approach is that the coefficient estimates from a logit or probit model can be used directly in the decomposition specification. The technique is thus useful for applications in which it is inappropriate to model the dependent variable as a linear function of the explanatory variables (Fairlie, 2006; Fairlie & Meyer, 1999). We can assess the contribution of each variable to the gap by observing the change in the average probability predicted by replacing one distribution (male) with the other (female), while holding the distribution of other variables constant. The contribution of each variable to the gap is equal to the change in the average predicted probability of replacing the female distribution with the male distribution of that variable while holding the distributions of the other variable constant. The main property of this technique is that the sum of the contributions of individual variables will be equal to the total contribution of all the variables evaluated in the sample. It should be noted that a potential endogeneity bias between income and financial inclusion may arise in this work. In fact, income, for example from farmers can be an outcome of financial inclusion that permits individuals to borrow for agricultural activities. To deal with that endogeneity issue, we follow Naghi et al. (2022) and Freedman and Sekhon (2010) who proposed a two-step procedure to overcome the endogeneity issue in probit model regression. In the first step, the study employs the ordinary least squares estimator, whereas, in the second step, the Probit Maximum Likelihood Estimator was fitted. In this step, the residuals are used as an additional regressor. The Probit estimates obtained are thus free from endogeneity biases Consanguineous Marriages and the Perception of Wife-Beating Justification in Pakistan: An Application of Fairlie Decomposition Empirical Methodology: To begin, descriptive statistics pertaining to various socioeconomic factors in consanguineous and nonconsanguineous marriages, as well as the prevalence of women’s perspectives concerning the justifying of IPV have been presented. The test of association is utilized to ascertain the variables that exhibit a statistically significant correlation with a woman’s rationale for her husband’s physical abuse of her. A logistic regression model was subsequently utilized to compute the odds ratios pertaining to each variable. For our main analytical part, we utilized the nonlinear decomposition method, as suggested by (Fairlie, 1999, 2005), to ascertain the extent to which various socioeconomic variables contribute to the disparity in the justification for IPV between the aforementioned types marriages. The endowment effect explains the disparity in the justification of IPV, which is attributed to the varying distribution of explanatory variables between consanguineous and non-consanguineous marriages. This implies that the justification gap can be eliminated if women in consanguineous marriages possess the same characteristics as those in non-consanguineous marriages. The second component pertains to the acceptance gap of IPV, which is influenced by unobservable factors that are not accounted for in the model. The process of nonlinear decomposition entails the estimation of the probability associated with justifying wife-beating for each individual woman within both the consanguineous and nonconsanguineous groups. This is accomplished by taking into account the model’s explanatory variables and by utilizing a sample that comes from one of the groups or a combined sample from the two groups. The predicted probabilities are then used to compare women from the two groups and evaluate the differences between them. This process is repeated multiple times (replications), and the results are averaged to obtain the final predicted gap. Given that there are different numbers of women in both groups (4,274 vs. 7,320), this study used the parameter estimates from the pooled sample to find the probabilities, as recommended by Fairlie (2005). To address the issue of path dependence (the sensitivity of the decomposition results to the order of introducing explanatory variables), we randomly ordered the variables across replications, following Fairlie’s recommendation (1999). We conducted 1,000 replications of this procedure. During the process of estimating the model, we utilized sample weights in order to take into consideration the intricate sampling strategy that was utilized in PDHS.
