Artificial Intelligence and the Rents of Finance Workers

This paper studies how artificial intelligence (AI) affects the finance labor market when
humans and AI perform different tasks in investment projects, and workers earn agency
rents that grow with project size. We identify two key effects of AI improvement: A freeriding
effect raises worker rents by increasing the probability of successful investment
when the worker shirks; A capital reallocation effect shifts investment toward workers
with higher or lower rents,...

Financial Restructuring and Resolution of Banks

How do resolution frameworks affect the private restructuring of distressed banks? We model a bank’s shareholders and creditors negotiating a restructuring, under two frictions: asymmetric information about asset quality, and externalities on the government. High-quality banks signal themselves by delaying the negotiation, which is socially inefficient. Public policies can improve welfare if they reduce the signaling motive or increase the negotiation surplus. Stricter bail-in rules make...

Algorithmic Pricing and Liquidity in Securities Markets

We let “Algorithmic Market-Makers” (AMMs), using Q-learning algorithms, choose prices for a risky asset when their clients are privately informed about the asset payoff. We find that AMMs learn to cope with adverse selection and to update their prices after observing trades, as predicted by economic theory. However, in contrast to theory, AMMs charge a mark-up over the competitive price, which declines with the number...

Inventory Management, Dealers' Connections, and Prices in OTC Markets

We propose a new model of trading in OTC markets. Dealers accumulate inventories by trading with end-investors and trade among each other to reduce their inventory holding costs. Core dealers use a more efficient trading technology than peripheral dealers, who are heterogeneously connected to core dealers and trade with each other bilaterally. Connectedness affects prices and allocations if and only if the peripheral dealers' aggregate...

Asset Dissemination through Dealer Markets

In over-the-counter markets for assets such as bonds or securitizations, large volumes can be split into smaller pieces and gradually sold to several nal investors with
the intermediation of multiple dealers. This paper proposes a model to study this process, called \asset dissemination". A dealer buys several units of an asset from a customer, then sells some units to his customers and to a...
