With climate change set to increase the frequency and intensity of flooding in the UK, it is important to deepen our understanding of the potential microeconomic impacts that may propagate into the macroeconomy. We integrate firm-level corporate records, with Ordnance Survey business-premise address information and publicly available flood maps to investigate two questions. First, what characteristics of firms are associated to the historical exposure and current risk of flooding; and second, what is the impact of flood events on corporate outcomes. We find significant sectoral, spatial and structural heterogeneity among firms in their risk and exposure to flooding. Larger firms are more likely to locate in flood zones, while small and medium-sized enterprises (SMEs) and natural-resource-related industries have historically been impacted most heavily.

Recently, Pflueger, Siriwardane and Sunderam (2020) proposed a new measure of investor risk perceptions based on the cross-section of stock prices. Using that measure, they found that when risk perceptions are high, the cost of capital of risky firms is high and subsequently real investment and employment decline in the United States. In this post, we show that similar relationships exist in the United Kingdom. In 2023 Q1, the UK measure fell to its lowest level since the outbreak of the Covid pandemic, indicating higher risk perceptions and potentially foreshadowing weaker economic activity. This indicator may be helpful for policymakers, as it could serve as a useful measure of risk perceptions relevant for future economic developments and monetary policy.
