Securing women's land rights is crucial for strengthening their bargaining power and improving opportunities for children. In our empirical study using panel data from three rounds of the Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA) in Ethiopia, we focus on assessing how joint land certification influences resource distribution among women and children within households. Our examination centers on evaluating bargaining power through intrahousehold resource-sharing rules. The results indicate that female-headed households allocate more resources to clothing, education, and hygiene consumption. Key factors affecting the bargaining process include the wife's education ratio positively impacting women's bargaining power, while the wife's age ratio has a negative influence. To ensure robust causal estimation, we employed coarsened exact matching (CEM) techniques for suitable matches between treated and control groups, applying a weighted fixed-effects model to the pruned dataset. Our findings emphasize the substantial positive impact of joint land certification on resource sharing for women and children combined, as well as child resources separately. Additionally, we created an empowerment index based on women's active involvement in critical agricultural decision-making domains. Using weighted fixed effects on the matched data, the results highlight the significant effect of joint land certification on enhancing women's empowerment.
