Land access, land rental markets and rural poverty dynamics in northern Ethiopian highlands: Panel data evidence using survival models por Ghebru, Hosaena, Holden, Stein

“…Applying both non-parametric (Kaplan-Meier estimator) and semi-parametric survival models that control for duration dependence of poverty transition, results show participation and degree of participation on the supply side of the tenancy market (landlords) have highly significant and positive effect on the chances of escaping poverty while the same cannot be said about the demand side of the tenancy market (tenants). The empirical evidence also confirms that households headed by older and literate people have relatively larger exit rates from poverty as compared to households headed by younger and illiterate ones. …”
