I study investors’ trade-off between ETFs and open-ended mutual funds in the presence of idiosyncratic liquidity risk and aggregate uncertainty. Based on a portfolio choice model, I show that ETFs and mutual funds provide liquidity at different maturities.…Read More
This project adapts online learning techniques to unstructured data, focusing on neural networks. We posit a non-parametric multi-armed bandit algorithm with context that uses a neural network for its underlying function approximation. We theoretically analyze and prove guarantees on the regret under this algorithm…Read More
This paper develops a theoretical model to study the economic incentives for a social media platform to moderate user-generated content. We show that a self-interested platform can use content moderation as an effective marketing tool to expand its installed user base, to increase the utility of its users, and to achieve its positioning as a moderate or extreme content platform.…Read More
Uber. Upwork. TaskRabbit. The world of work is transforming and my research agenda attempts to identify and explain 1) how work is changing and 2) how these changes affect workers, especially those who are marginalized or vulnerable.…Read More
We investigate whether the effect of network position on innovation is causal or spurious. Although empirical evidence demonstrates that certain structural positions in alliance networks (e.g. structural holes) affect firm innovation, it is hard to disentangle the factors allowing a firm to put itself in a certain position from the innovation outcomes that stem from being in that position.…Read More
Globally, 1.5 billion people live off the grid, their only access to electricity often limited to operationally-expensive fossil fuel generators. Solar power has risen as a sustainable and less expensive option, but its generation is variable during the day and non-existent at night.…Read More
I quantify the impact of trade secret protection on labor outsourcing, and consequently, on aggregate productivity.…Read More
We show that financial reporting spurs consumer behavior. Using granular GPS data, we show that foot-traffic to firms’ commerce locations significantly increases in the days following their earnings announcements.…Read More
Tolga Dizdarer, PhD Candidate, The Wharton School, Gerry Tsoukalas, Operations, Information & Decisions, The Wharton School, and Gérard Cachon, Operations, Information & Decisions, The Wharton School Abstract: Service platforms like Uber and AirBnb create markets that connect customers with service providers. Platforms provide the medium of interaction and receive commissions from…Read More
We establish the relevance of human capital to startup financing. Using administrative databases from the Central Bank of Brazil, we obtain information on private firms, their founders and their access to bank credit.…Read More
How can rooftop solar owners capture economic value from investing in battery technologies? Storage adds at least three strategic options for homeowners that previously could only directly consume solar generation and sell any excess instantaneously, thus they traditionally relied on feed-in tariffs or other subsidies.…Read More
We investigate the impact social movements have on firm-level innovation through private politics. We distinguish between contentious private politics, or contentious targeting of firms by activists, and cooperative private politics, when activists engage firms in formal collaborations.…Read More
Most digital communication platforms store content and allow users to see it multiple times. Despite the benefits that recording content holds for both users and companies, many applications delete it after it was seen by the receiver (i.e., ephemeral communication channels). …Read More
We empirically show people tend to associate a higher valuation of Bitcoin with a higher Bitcoin exchange rate, and such exchange rate has significant impacts on both the supply and demand of the mining rigs.…Read More
This study aims to measure the impact of General Data Protection Regulations on firms and consumers. Specifically, we plan to document GDPR’s impact on consumers search and discovery of products, and firm’s ability to reach out and sell to a broad set of consumers.…Read More
Advances in intelligent technologies change the way consumers search and shop for products. Emerging is the trend of home-shopping devices such as Amazon’s Alexa and Google Home, which allow consumers to search or order products using voice commands.…Read More
Transition services agreements (TSAs) are an important tool that companies use to manage the process of separating business units from their former corporate parents in spinoff transactions. …Read More
The goal of our paper is to study whether machine learning can be used to infer tips that can help workers learn to make better decisions. …Read More
Few studies have examined the impact of divestitures on the innovation performance of firms. In particular, little attention has been paid into how the divestiture of firms’ non-core businesses could influence the innovation outcomes of their core businesses. …Read More
Group formation tends to involve peer effects. I provide a new sufficient condition for the non-emptiness of the core of network formation games that involve pairwise complementarities between peers.…Read More
