Title: Climate Change and Innovation: Beyond Policy?

Abstract:
Technologies are an essential part of the global fight against climate change. Because of market failures leading to under-investment in research and development, much of the literature on the drivers of innovation in climate technologies focuses on the role of regulation. However, climate change disrupts global supply chains, affects access to raw materials, changes consumer preferences, and impacts stock performance, thereby altering incentives to innovate and adopt technologies even in the absence of regulation. This paper asks whether we can empirically detect a systematic effect of climate change on innovation and technology adoption for climate-related technologies, beyond the effect of policies and across countries of different income levels. To answer this question, I construct a dataset of climate change exposure and vulnerability, as well as patent filings, trade flows, and policies in climate mitigation and adaptation for 59 countries from 1995-2017. I find significant heterogeneity across income groups in terms of whether patent filings are principally driven by policies or by climate vulnerability, whether vulnerability has a positive or negative effect on filings, and whether filings represent new innovation or adoption of foreign technologies..
