OxTalks is Changing
OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected in early Hilary to allow all events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed as soon as possible.

Climate Change, Firms, and the Aggregate Productivity
This paper presents a general equilibrium structural framework that separates the effects of temperature on firm-level demand, productivity, and input misallocation to examine the aggre- gate productivity losses caused by climate change. By analyzing data from Italian firms, that cover approximately 75% of aggregate gross output, and incorporating detailed climate data, the paper reveals an inverted U-shaped relationship between temperature and firm-level outcomes such as productivity and capital misallocation. Leveraging these micro elasticities, the paper projects the aggregate productivity losses resulting from climate change scenarios. The findings indicate a significant and nonlinear relationship between climate change and aggregate productivity, with a projected 2-degree Celsius increase leading to a 1.8% decline. Doubling the expected increase to 4 degrees exacerbates the decline nearly fourfold to approximately 6.4%. Finally, the analysis highlights widening regional disparities as a consequence of climate change.
