However, little empirical attention has been paid to the processes through which such learning occurs. Focusing on the South African...

Mount Manengouba culminates at 2,411 m and is characterized by important geomorphological features (geomorphosites), namely, two nested sub-circular calderas (Elengoum and Eboga), broken cones, crater lakes (Female, Male and Beme), and domes and basin (Djeu-Seh). These geomorphosites constitute an asset for geotourism and other anthropogenic...

This paper studies the effect of women's higher education on fertility outcomes in Ethiopia. We exploit an abrupt increase in the supply of tertiary education induced by a liberalisation policy. Using an age discontinuity in the exposure to higher education reform, we find that education lowers fertility by 8% and increases the likelihood of never giving birth by 25%. We explore the role of potential underlying mechanisms and find that this negative effect on fertility is channelled through...

This paper studies the effect of women’s higher education on fertility outcomes in Ethiopia. We exploit an abrupt increase in the supply of tertiary education induced by a deregulation policy. Using an age discontinuity in the exposure to higher education reform, we find that education lowers fertility by 8% and increases the likelihood of never giving birth by 25%. We explore the role of potential underlying mechanisms and find that this negative effect on fertility is channeled through...
