Research Agenda

My research examines how climate change reshapes firm productivity, market structure, and technological change, focusing on the micro-to-macro channels through which firms adapt, reallocate, and innovate. I combine firm-level data, production-function estimations, and endogenous-markup models to quantify climate damages when technology and market power respond endogenously.

Extreme Heat and Directed Innovation

Extreme heat acts as a labor-biased productivity shock, triggering capital deepening and labor-saving directed innovation. Induced innovation offsets ~26% of heat-related productivity losses in EU manufacturing (2000–2020).

Climate Change and Market Power

Extreme heat increases concentration and aggregate markups by shifting share from heat-vulnerable small firms to large firms. In a variable-elasticity model, endogenous markups amplify welfare losses relative to CES benchmarks.

Misallocation of Climate Innovation — Adaptation vs Mitigation

Are we over-investing in mitigation and under-investing in adaptation? Measures the global imbalance in climate innovation and maps observed patent portfolios to socially optimal "wedges" using a dynamic planner framework and global patent data.

Future Directions

My future research agenda extends along several directions:

• Climate-driven creative destruction
• Demand side climate adaptation
• Emission account along the supply chain
• Market power and optimal climate policy design
