From Text to Image to Video: Exploring Generative AI for Public Interest Communication
Generative AI is often viewed as a threat to truth and trust, yet it can also be harnessed for the public good. This talk examines how text-, image-, and video-based AI tools shape public interest communication across three studies. The first study tests AI-generated vaccine correction messages tailored to personality and belief profiles, showing both the promise of scalable targeting and the risks ...

How Does Active Involvement Benefit Investors? Evidence from 85 Billion Cell Phone Signals
I investigate the reputation effects of active involvement, specifically examining how venture capitalists’ (VCs’) on-site meetings with portfolio companies affect VCs' reputations and future deal flow. By analyzing cell phone signals collected around VC and startup office buildings from 2018 to 2023, I measure VCs’ involvement intensity and deal flow quality. Using exogenous variation in travel ...

Does Financial Integration Eliminate the Diabolic Loop?
This paper studies the impact of cross-border banking integration on the sovereign-bank loop in a multi-country setting. Sovereign debt serves as collateral in the interbank market and its value underpins the investment of banks with access to productive projects. Bad news about the likelihood of debt repayment in the future reduces the collateral value of government debt leading to lower investment ...

When Historical Prices Becomes Transparent, Must Consumers Be Better Off?
Recent years have witnessed a growing number of online platforms disclosing the historical prices of products to consumers. While such transparency is typically viewed as consumer-friendly, this paper shows that it can raise prices and reduce consumer welfare. We develop a dynamic model in which a seller faces sequential consumers who are uncertain about product quality and rely on past consumer reviews....

How Costly are Trading Biases?
We analyze a broad set of buy-side trading biases identified in leading finance journals over the past 75 years. Using 14.5 years of trade-level data for retail and institutional investors, we find that roughly 20 percent of documented biases are no more prevalent among retail investors than would be expected from random trading, while retail investors display about three times as many biases as institutions....

Quantity-Biased Technological Change
Skill-biased technological change has long been linked to rising wage inequality. New technologies also allow firms to expand their scope of their operation. We formalize such quantity-biased technological change in a model where heterogeneous firms with decreasing returns to scale choose the size and quality of their white and blue-collar worker pools. We characterize the equilibrium assignment and ...

Optimal Auction Design for Dynamic Stochastic Environments: Myerson Meets Naor
Allocation of goods and services often involves both stochastic supply and stochastic demand. Motivated by applications such as cloud computing, gig platforms, and blockchain auctions, we study the design of optimal selling mechanisms in an environment where buyers with private valuations arrive stochastically and are assigned goods that also arrive stochastically, and either buyers or goods can be ...

Robust Benchmark Satisficing
We propose a robust benchmark satisficing framework for data-driven decision-making under uncertainty, designed to identify decisions whose expected revenue exceeds that of a comparator by a user-specified surplus—even when the true distribution is unknown. This framework generalizes the robust satisficing model of Long et al. (2023), by accommodating a broader range of benchmark-driven decision criteria ...

Price-Cut Commitment under Strategic Inventory and Retailer Dominance
Problem definition: Dominant retailers often pressure manufacturers to commit to future wholesale price reductions, yet the implications of such price-cut commitments---particularly when retailers can also hold strategic inventory---are not fully understood. The decision is further complicated when multiple retailers compete for supply, as both commitments and inventory strategies influence upstream ...
