讲座概述

We study the impact of ESG ratings on firms’ voluntary disclosures of sustainability data. Our analysis exploits Refinitiv’s 2020 methodology recalibration, which penalizes non-disclosure of ESG data points and generates widespread revisions in firms’ ESG scores, absent changes in their fundamentals. Using the comprehensive sustainability data points underlying Refinitiv’s ESG scoring, we find that firms with a more negative recalibration-driven score revision exhibit a greater subsequent increase in the disclosure intensity of these data points. The effect is stronger among firms with larger ownership by sustainability-sensitive institutional investors and covered by alternative leading ESG raters. Additional analyses find that firms with more negative score revisions improve their subsequent ESG scores and are more likely to receive E&S certifications, particularly those with increased disclosures. Overall, these findings are consistent with ESG ratings incentivizing firms to provide transparent and relevant sustainability data disclosures to meet investor demand.

讲座概述

I develop a dynamic model of internal capital allocation within conglomerates facing liquidity shocks, in which affiliate firms differ in their innovation potential. I define cutoff rules for when to liquidate low-productivity firms, coerce intermediate types into short-term strategies, or preserve high-potential firms for long-term R&D. Embedding these margins into an endogenous growth model, I show that the optimal strategy evolves over time: coercion preserves liquidity in early stages of conglomerate development but becomes suboptimal as gains from short-term innovation diminish once the conglomerate approaches the technological frontier. I illustrate the changing tradeoff across conglomerate development level through comparing the optimal strategy with two inefficient ones: a coercion trap, where short-termism persists too long, and a liquidation fallacy, where viable firms are discarded prematurely. My framework offers microfoundations for internal capital reallocation and policy insights for restructuring within business groups.

讲座概述

We establish a necessary and sufficient condition for the quantile process based on iid sampling to converge in distribution in L1(0,1). The condition is that the quantile function is locally absolutely continuous on the open unit interval and satisfies a slight strengthening of square integrability. We further establish a necessary and sufficient condition for the P-P process based on iid sampling from two populations to converge in distribution in L1(0,1). The condition is that the P-P curve is locally absolutely continuous on the open unit interval. If either process converges in distribution then it may be approximated using the bootstrap.

讲座概述

We use rich social media data and large language models to classify retail investors’ trading strategies and link them to sentiment and market outcomes. Investors’ strategy adoption is highly dynamic, shifting with news arrivals, past performance, and social feedback. Sentiment from Fundamental Analysis predicts positive future returns, while sentiment from Technical Analysis and other speculative strategies predicts negative returns. Technical sentiment is especially correlated with retail buying, most prominently among Robinhood investors. These findings provide new evidence on how retail investors form and adapt strategies, and on the conditions under which retail trading informs or distorts markets.
