Infrastructure can drive development, but history shows it can also be used for political control. Paraguay’s roads under Stroessner's dictatorship highlight this dual nature, providing valuable lessons for today’s policymakers.

We study best linear predictions in a context where the outcome of interest and some of the covariates are observed in two different datasets that can-not be matched. Traditional approaches obtain point identification by relying, often implicitly, on exclusion restrictions. We show that without...

We provide experimental evidence of teacher-to-student transmission of gender attitudes in Pakistan. We randomly show teachers a pro-women’s rights visual narrative. Treated teachers increase their and students’ support for women’s rights, unbiasedness in gender IATs, and willingness to petition...

We examine various forms of helping behaviour among Tsimane Amerindians of Bolivia, focusing on the provision of shelter, childcare, food, sickcare, cultural influence and traditional story knowledge. Kin selection theory traditionally explains nepotistic nurturing of youth by closely related kin....

Motivated by finding a way to deal with Compositional Data (CoDa) with or without zeroes in a unified way, we build upon the previous projective geometry viewpoint of Faugeras (2023) and use the tools provided by the exterior product and Grassmann’s algebra. These allow to represent higher...

We use data from a platform that centralizes day care matching and estimate parents’ preferences and nursery priorities from rank-ordered lists and acceptance decisions. Our novel estimation approach, inspired by dynamic discrete choice models, accounts for strategic behavior. We then evaluate...

We study the sustainability of sovereign debt under the assumption of involuntary and costly default: governments do their utmost to avoid default, which reduces the resources available for debt service. We show that costly default tightens Blanchard’s g > r condition. We derive a formula for a...

This paper revisits the link between strategic trade policies and the mode of competition in the product market, emphasizing the emergence of a different mode of competition if only one of the two governments implements such a policy. We show that with an endogenous mode of competition and an...

Understanding the dynamics of inter-group cooperation in human adaptation has been the subject of recent empirical and theoretical studies in evolutionary anthropology, beginning to fill gaps in our knowledge of how interactions across political, economic and social domains can – and often do –...
