SEM217: Daniele Ballinari, University of Basel: From Chatter to Action: An Index of Sustainability Sentiment
Tuesday, November 2nd @ 11:00 - 12:30 PM (ONLINE)
ABSTRACT: Investments in sustainable assets have grown at a rapid pace over the last decade, amounting to a third of assets under management in the US today. Theoretical models partially attribute this increase to changes in investor taste for sustainability.

ABSTRACT: Many investors have shifted their asset allocations to account for Environmental, Social, and Governance (ESG) issues. While we welcome this shift from an ethical perspective, the financial and non-financial benefits of ESG investing as well as best practices for portfolio construction are subjects of heated debate. We look at aspects of the debate through a series of practical examples.

ABSTRACT: Statistical arbitrage identifies and exploits temporal price differences between similar assets. We propose a unifying conceptual framework for statistical arbitrage and develop a novel deep learning solution, which finds commonality and time-series patterns from large panels in a data-driven and flexible way.

ABSTRACT: General Equilibrium (GE) models are the most natural economic models for studying policies to mitigate human-induced climate change. In particular, they provide a setting in which we can analyze the effects on income distribution of climate mitigation policies such as carbon taxes or cap-and-trade, and develop policies to offset the income distribution effects. Most economic models of climate change are partial equilibrium, and thus have a limited ability to address the effects of climate mitigation policies on income distribution.

ABSTRACT: We examine hurricane exposure as a systematic risk factor in the US stock market. Using a consumption-based asset pricing model with heterogeneous agents subject to uninsurable shocks, we derive a necessary and a sufficient condition for a hurricane risk premium.

ABSTRACT: We study the problem of decision-making in the setting of a scarcity of shared resources when the preferences of agents are unknown a priori and must be learned from data. Taking the two-sided matching market as a running example, we focus on the decentralized setting, where agents do not share their learned preferences with a central authority.

ABSTRACT: When large idiosyncratic shocks hit a cryptocurrency, some of its peers experience un- usually large returns of the opposite sign. The co-movement is concentrated among peers that are co-mentioned with shocked cryptos in the news, and that are listed in the same exchanges as shocked cryptos. It is a form of mis-pricing that vanishes after several weeks, giving rise to predictable returns. We propose a profitable trading strategy that exploits this predictability, and explain our results with a slow information processing mechanism.
SEM217: Vikramaditya (Vic) Khanna, University of Michigan: Insuring against wrongdoing? Socially responsible investing by mutual funds
Tuesday, October 12th @ 11:00 - 12:30 PM (ONLINE)
ABSTRACT: We examine whether mutual funds increase the level of their socially-responsible investing (SRI) to reduce the negative consequences stemming from alleged wrongful behavior by fund insiders. Relying on a novel hand-collected dataset covering 17 years of funds’ fidelity bond claims (for theft and embezzlement by insiders) and errors and omissions claims (for mistakes) we find that funds significantly increase their SRI in the year of a claim, but not in the year before or after the claim.

Tuesday, October 19th @ 11:00 - 12:30 PM (ONLINE)
ABSTRACT: Increasingly, algorithms are supplanting human decision-makers in pricing goods and services. To analyze the possible consequences, we study experimentally the behavior of algorithms powered by Artificial Intelligence (Q-learning) in a workhorse oligopoly model of repeated price competition.
SEM217: Jeff Bohn, One Concern & CDAR: Evaluating commercial property resilience with hybrid physics-based/ machine learning (ML) models
Tuesday, October 26th @ 11:00 - 12:30 PM (ONLINE)
ABSTRACT: As more property-related data are becoming available, unprecedented granular analyses have become facilitated with hybrid methodologies that incorporate machine learning (ML) into physics-based models.
