*Extreme weather events have significant implications for the production decisions of smallholder farmers. While previous research highlighted investments in sustainable land management (SLM) and changes in farm and off-farm labor supply as adaptation strategies, little is still known about how cultural practices affect these decisions. Our study setting is Malawi, a country with distinct matrilineal and patrilineal kinship customs that govern land ownership. We study the extent to which plot owners delegate farm decisions to their spouses in response to adverse rainfall shocks in Malawi and the implications for farm labor supply and investment in adaptation technologies. Using plot-level cross-sectional data from 2116 farm households combined with meteorological stations' rainfall data, we estimate the effect of weather shocks during the 2012/2013 agricultural season on the delegation of production decisions in patrilineal and matrilineal farm households. In the face of adverse rainfall shocks, the management of patrilineal plots, where men held the majority of land rights, is more likely to be delegated to the spouse. In matrilineal households, the opposite pattern emerges. We also present some suggestive evidence that kinships adopt distinct coping strategies, as evidenced by the higher investments in SLM and the increase in farm labor supply among matrilineal households as compared to patrilineal households.

**Protective behaviors play a central role in controlling the spread of infectious diseases. Regarding COVID-19, there exists a large variety of prophylactic measures recommended by health authorities. Until now, most of the literature on the determinants of COVID-19 protective behaviors at the individual level focused on either one of those behaviors or studied several behaviors but independently from each other’s. However, protective behaviors might not be independent of each other’s and the question of the relationship between these various behaviors deserves to be further investigated. The aim of this study is to investigate the relationships between three types of COVID-19 protective behaviors among a representative sample of the French population (the RESPIRE survey, N=1017): 1) respect of sanitary rules issued by the government, 2) use of Non-Pharmaceutical Interventions (NPIs) and 3) COVID-19 testing. Using a Latent Class Analysis, we identify four groups with diverging patterns of compliance with protective behaviors, differing both in terms of intensity and types of prophylactic measures followed: 1) individuals who apply all protective behaviors, 2) those who reject them all, 3) those who frequently break sanitary rules but stick to NPIs and, 4) those who follow sanitary rules but lightly apply NPIs. When looking at the factors associated with class membership, we find that the adoption of different patterns of protective behaviors is highly correlated with individuals’ time and risk preferences as well as their prosociality and interpersonal trust. Our results suggest that the relationship between various COVID-19 protective behaviors differs depending on individuals, those behaviors being substitutable for some and complementary for others, with important public health implications in terms of pandemic control.
