This paper studies the identification and estimation of a semiparametric binary network model in which the unobserved social characteristic is endogenous, that is, the unobserved individual characteristic influences both the binary outcome of interest and how links are formed within the network. The exact functional form of the latent social characteristic is not known. The proposed estimators are obtained based on matching pairs of agents whose network formation distributions are the same. The consistency and the asymptotic distribution of the estimators are proposed. The finite sample properties of the proposed estimators in a Monte-Carlo simulation are assessed. I conclude this study with an empirical application.

This paper establishes the identification and provides an estimation algorithm of a nonparametric dyadic regression model where the unknown structural function is nonseparable, and the distribution of the unobservable random terms is assumed to be unknown. The identification and the estimation of the distribution of the unobservable random term are also proposed. I assume that our structural function is left-continuous and weakly increasing in the unobservable random terms. Moreover, I propose suitable normalization for the identification by allowing the structural function to have some desirable properties such as homogeneity of degree one in the unobservable random term and some of its observables. I conclude this study by assessing the finite sample properties of the proposed estimators in a Monte-Carlo simulation.

Trust is increasingly perceived as having a significant effect on trade, public goods provision, conflict resolution and even democratic consolidation. Using individual data from Afrobarometer survey rounds 6 and 7 in Africa, I find that citizens originated from the anglophone countries are more likely to trust local leaders than those originated from the francophone countries. Systematic tests of this finding are complicated by unobserved heterogeneity among nations due to variable pre- and post-colonial histories. In order to address endogeneity issues, I focus on Cameroon which includes regions colonized by both Britain and France, and I exploit the natural experiment provided by the anglophone-francophone border to identify the long term effects, if any, of both English and French colonization on trust using regression discontinuity on observations near the border. I show that regions on the British side of discontinuity have higher levels of trust toward local leaders. Although the ability to identify causal mechanisms is limited, the evidence suggests that communities on the British side have benefited from a policy of indirect rule and the lack of forced labor, which has produced stronger local institutions.

To what extent can Africa’s present-day ethnic-based discrimination be traced back to its colonial policies? This paper investigates the enduring impact of British colonial policies on ethnic discrimination in West Africa. Using individual data from Afrobarometer surveys rounds 7 and 8, covering 31 African countries, we examine whether the British Indirect Rule system has contributed to current levels of ethnicity-based discrimination. Our findings reveal that individuals in former British colonies are significantly more likely to experience ethnic discrimination.
