Exacerbation of extreme weather events by climate change provoked a recent surge in scientific papers examining their consequences. The present article contributes to the literature by investigating the potential effects of meteorological disasters on public debt in middle- income countries. Rising debt may limit the ability of emerging countries to cope with unanticipated crisis and prevent their ability to develop, therefore it is crucial to understand the effects of disasters on public debt and its components. Our empirical analysis includes disaster data from the CRED and gross public debt extracted from the WEO. We employ a local projection estimator on a sample of 18 middle-income countries in Asia that have experienced frequent exposure to severe weather events between 2002 and 2019. Although results do not exhibit significant effects of meteorological disasters on debt variation when we consider all the events, we find negative, significant, and robust effects of extreme meteorological events on debt variation when focusing on the 15% deadliest events. Our findings suggest that countries frequently exposed to disasters have been able to limit sovereign debt growth because of external funding.

This study is part of the in-depth research on poverty in Côte d'Ivoire. It aims to assess the pro-poor nature of growth by distinguishing three periods: 2002 - 2008, 2008 - 2015 and 2015 - 2018. The specific aim was to analyze the pro-poor growth indicators defined by Ravallion and Chen, Kakwani & Perni for these three periods, and to identify the determining factors using decomposition methods. The results obtained indicate that, at national level, growth was pro-poor only over the 2008 -2015 and 2015 - 2018 periods, with the main factor being the effect of growth in the incomes of the poor for the first period and the redistribution effect for the second period. For the period 2002 - 2008, growth was not poor. The analysis of contrasts according to area of residence revealed that the rural poor benefited from the effects of growth over the three study periods, while the urban poor were only pro-poor over the 2008 -2015 and 2015 - 2018 periods.

The exchange of private data associated with the growing use of algorithms and artificial intelligence has significantly grown since the beginning of the 21st century. Households are marginally involved in this sharing process and are, most often, unaware of the existence of these exchanges and their purpose. Due to the transversality of this digital transformation, they are subjected daily, either with minimal consent or voluntarily, to algorithms in order to perform various economic activities such as the delegation of their savings or retirement. Given recent developments in the wealth management industry with the introduction of Robo-advisors, this paper focuses on the determinants of individuals’ sensitivity to the management of private data used to feed algorithms or artificial intelligence in the context of investment delegation decisions. We attempt to propose an experimental protocol that measures this said sensitivity by exposing individuals to data leaks in varying investment tasks. The presentation will consist of a live demonstration of the experiment.
