Dance for the Rain of Pay for Insurance? An Empirical Analysis of the Italian Crop-Insurance market
w/ Luca Citino and Matteo ParadisiAbstract: Despite the increased frequency of extreme weather events, the use of climate-related crop insurance contracts in European countries remains low. We investigate the economic factors behind these low coverage rates by linking Italian administrative data on insurance purchases and damage claims to high-frequency georeferenced data on weather events. We focus on two potential explanations: inefficient pricing of insurance contracts due to adverse selection and choice frictions that create a wedge between the value of insurance and actual demand. To identify adverse selection, we leverage a 2014 reform that lowered the cap for premium subsidies in EU countries. This policy caused a reduction in demand and an increase in average costs for insurers, indicating adverse selection. Regarding frictions, we document through a staggered difference-in-differences design that firms are more likely to buy insurance when faced with “salient” extreme events, suggesting that farmers are imperfectly informed about the value they assign to insurance. We conclude by discussing how current price subsidies may be less effective than insurance mandates in light of these uncovered market failures.
Some (don’t) Like it Hot. Persistent High Temperatures Increase Depression and Anxiety
w/ Giulia MartinelliAbstract: We study the impact of high temperatures on milder mental health outcomes using clinical data from a large-scale program in England that provides treatment for depression and anxiety in a setting with limited opportunities for heat avoidance. Exploiting monthly temperature variations at the Clinical Commissioning Group level, we find that extreme heat, i.e. temperatures above 34°C, increase the demand for mental health support, assess- ments, and treatments by approximately 10%, 15%, and 12%, respectively. The effects are particularly pronounced during prolonged heat shocks, especially heat waves lasting more than ten days. The results are not affected by prior exposure to similar heat stress and are more pronounced in areas with higher socio-economic status, as proxied by housing prices. We find similar effects within the same temperature range when examining medi- cal prescriptions for anxiolytics and antidepressants. Our back-of-the-envelope calculation suggests that the monetary health costs associated with heat stress are substantial.
