We study optimal monetary policy during temporary supply contractions when aggregate demand has inertia and expansionary policy is constrained. In this environment, it is optimal to run the economy hot until supply recovers. Positive output gaps in the low-supply phase lessen the negative output...

This study examines the stock market reactions to the Russian invasion on Feb. 24 in 2022. Using an event study methodology, we document that the war has a different impact on stock markets across countries and sectors, depending on how deeply the countries or industries are involved in the war....

We construct various measures of firm-level climate risk exposure by utilizing two natural language processing techniques (LDA and word2vec) on firms‘ quarterly earnings conference call transcripts. The unsupervised learning method automatically generates five topics, all aligned with popular...

The last 60 years of research striving to explain the post-earnings announcement drift (PEAD) have resulted in numerous potential explanations. This ”zoo” of explanations, limited academic consensus, and a literature relying on thousands of earnings announcement make researchers able to...

Since the explosion of the Russia-Ukraine war, the global stock markets have experienced considerable oscillation. Using data for 86 countries, this paper provides a comprehensive analysis to identify the roles of geopolitical, economic, institutional, humanitarian, industrial, and firm-related...

We propose a model where monetary policy is the key determinant of aggregate asset prices (financial conditions). Spending decisions are made by a group of agents ("households") that respond to aggregate asset prices, but with noise, delays, and inertia. Asset pricing is determined by a...

We propose a new non-linear single-factor asset pricing model. Despite its parsimony, this model represents exactly any non-linear model with an arbitrary number of factors and loadings - a consequence of the Kolmogorov-Arnold representation theorem. It features only one pricing component...

We develop a segmented markets model which rationalizes the effects of monetary policy on the term structure of interest rates. When arbitrageurs' portfolio features positive duration, an unexpected rise in the short rate lowers their wealth and raises term premia. A calibration to the U.S....

We study the impact of green investors on stock prices in a dynamic equilibrium model where investors are green, passive or active. Green investors track an index that progressively excludes the stocks of the brownest firms; passive investors hold a value-weighted index of all stocks; and active...
