Climate change, firms, and aggregate productivity

This paper uses a general equilibrium framework to examine the effects of temperature on firm-level demand, productivity, and input allocation efficiency, deriving an aggregate damage function for climate change. Using data from Italian firms and detailed climate data, it uncovers a sizable negative effect of extreme temperatures on firm-level productivity and revenue-based marginal product of capital.

Back to school when times are bad? The role of housing wealth

College enrolment typically rises during recessions. This paper demonstrates that housing wealth destruction dampened this countercyclical effect in areas most affected by the U.S. housing bust of 2008-2011. By combining household data with a mortgage credit register and housing price data, we reveal that negative shocks to housing wealth significantly reduced college enrolment among homeowners relative to renters during this period. Up to 2% of the local college-age population did not pursue college enrolment at the height of the bust due to housing wealth destruction.

From words to deeds – incorporating climate risks into sovereign credit ratings

We investigate the impact of climate risks on sovereign credit ratings worldwide. Our analysis shows that higher temperature anomalies and more frequent natural disasters – measures of physical risk – correlate with lower credit ratings. We find that long-term shifts in climate patterns (“chronic risk”) primarily affect advanced economies, while the increased frequency and severity of extreme weather events (“acute risk”) matters more for emerging economies. However, the estimated impact of both types of risk on credit ratings is low and the economic effects are negligible.

Tariffs across the supply chain

What are the macroeconomic impacts of tariffs on final goods versus intermediate inputs? We set up a two-region, multi-sector model with production networks, sticky prices and wages, and trade in consumption, investment, and intermediate goods. We show that import tariffs on final goods have a smaller negative impact on GDP compared to tariffs on intermediate inputs, as final goods can be more readily substituted with domestic alternatives.
