Working Papers

esg returns
Unconstrained investors have outperformed in their ESG investments over the last 15 years. Figure shows cumulative excess returns within the top quantile of unconstrained ownership of stocks with different ESG levels.

We document a positive Environmental Social Governance (ESG) premium amongst stocks with high socially unconstrained ownership. Unconstrained investors are mutual funds, hedge funds and other investment advisors. This premium does not appear for stocks with high socially constrained ownership. In fact, we find that constrained investors unsuccessfully chase high ESG stocks with high abnormal returns. The returns do not seem to be driven by consumption risk as they are especially high during the financial crisis. Instead, they are explained by the new fact that unconstrained investors are skilled investors who research firms and are able to predict their future ESG scores. This earns them an abnormal return due to a ESG premium. We further show that they are able to exploit this especially during periods of high climate sentiment and in times of crisis. In the process, we construct a new text-based sustainability sentiment measure and create both an ESG and climate factor, that are useful for asset pricers to explain ESG firms' rise in value, their generally high valuations as well as risk exposures.

Fire Sales
When countries increase their macroprudential buffer it increases the price of risk (Sharpe Ratio) in their respective economies.

Presented at: Wharton School at the University of Pennsylvania, PhD Nordic Finance Workshop, Poster Session at American Finance Association Annual Meeting (AFA), Copenhagen Business School.

I document that equity prices fall as macroprudential buffers are announced. This is consistent with macroprudential buffers leading to an increase in risk premia, from a heightened price of risk. Theoretically, I develop a model that predicts that as buffers are announced 1) The price of risk increases, 2) Systemic risk falls, and 3) Intermediaries' risky asset allocation decreases, as other agents with higher risk aversion increase their portfolio weights in the risky asset. Empirically, I find evidence consistent with the first and third prediction. The second remains a testable implication of my model. In summary, this paper sheds light on the equilibrium effects of implementing new financial regulation on asset prices and systemic risk.

Fire Sales

Identification and Assessment of Systemic Risks in Financial Networks: Modelling Fire Sales from Regulatory Cliff Effects, Danmarks Nationalbank Working Paper, Number 117.

This paper investigates fire sales triggered by regulatory cliff effects induced by the loss of Capital Requirements Regulation (CRR) compliance on covered bonds. The loss of CRR compliant status leads to banks holding these covered bonds to lose several regulatory advantages, one consequence being a lower solvency. In our analysis, following the loss of CRR compliance, banks sell off their covered bonds in a fire sale, in an attempt to return to their initial solvency, resulting in losses of equity for the system as a whole. Further, we find that, for price impacts larger than a critical threshold, even small shocks lead to explosive fire sales and large losses of equity. While these losses can be averted if the banks allow their solvency levels to fall temporarily, other regulations, such as those relating to large exposures to other banks, could still trigger similar fire sales.
